    The significance of Science Framework (SF) to date is receiving more acceptances all over the world to address agricultural sustainability. The professional views, however, advocate that the SF known as Mega Science Framework (MSF) in the transitional economies is not converging effectively in many ways for the agricultural sustainability. Specially, MSF in transitional economies is mostly incapable to identify barriers in agricultural research, inadequate to frame policy gaps with the goal of strategizing the desired sustainability in agricultural technology and innovation, inconsistent in finding to identify the inequities, and incompleteness to rebuild decisions. Therefore, this study critically evaluates the components of MSF in transitional economies and appraises the significance, dispute and illegitimate issue to achieve successful sustainable development. A sound and an effective MSF can be developed when there is an inter-linkage within principal components such as of (a) national priorities, (b) specific research on agricultural sustainability, (c) adequate agricultural research and innovation, and (d) alternative policy alteration. This maiden piece of research which is first its kind has been conducted in order to outline the policy direction to have an effective science framework for agricultural sustainability.

  10. Testing the effect of a science-enhanced curriculum on the science achievement and agricultural competency of secondary agricultural education students

    NASA Astrophysics Data System (ADS)

    Haynes, James Christopher

    Scope and Method of Study. The purpose of this study was to determine if a science-enhanced curriculum produced by the Center for Agricultural and Environmental Research and Training (CAERT) taught in a secondary level animal science or horticulture course would improve students' understanding of selected scientific principles significantly, when compared to students who were instructed using a traditional curriculum. A secondary purpose was to determine the effect that the science-enhanced CAERT curriculum would have on students' agricultural knowledge when compared to students who were instructed using a traditional curriculum. The design of the study was ex post facto, causal comparative because no random assignment of the treatment group occurred. Findings and Conclusions. No statistically significant difference was found between the treatment and comparison groups regarding science achievement. However, the mean score of the treatment group was slightly larger than the comparison group indicating a slightly higher achievement level; a "Small" effect size (d = .16) for this difference was calculated. It was determined that a statistically significant difference (p < .05) existed in agriculture competency scores in animal science (p = .001) and horticulture (p = .000) as a result of the treatment. Moreover, this was considered to be a "very large" effect (d = 1.18) in animal science and a "large" effect (d = .92) in horticulture. When considering student achievement in science, this study found that the use of the science-enhanced CAERT curriculum did not result in a statistically significant increase (p < .05) in student performance as determined by the TerraNova3 science proficiency examination. However, students who were instructed using the CAERT curriculum scored better overall than those who were instructed using a "traditional" curriculum.

  14. The Impact of Agricultural Science Education on Performance in a Biology Course

    NASA Astrophysics Data System (ADS)

    Ernest, Byron L.

    The lack of student achievement in science is often cited in U.S. educational reports. At the study site, low student achievement in science has been an ongoing concern for administrators. The purpose of this mixed methods study was to investigate the impact of agricultural science education on student performance in a Biology course. Vygotsky's constructivist theory and Gardner's multiple intelligences theory provided the framework for the study. The quantitative research question examined the relationship between the completion of Fundamentals of Agriculture Science and Business course and student performance in Biology I. Teacher perceptions and experiences regarding the integration of science and agricultural curriculum and traditional science curriculum were examined qualitatively. A sequential explanatory design was employed using 3 years of data collected from 486 high school students and interviews with 10 teachers. Point-biserial correlation and chi square tests revealed statistically significant relationships between whether or not students completed Fundamentals of Agriculture Science and Business and Biology I course performance, as measured by the end of course assessment and the course grade. In the qualitative sequence, typological and inductive data analyses were applied to the interview data, and themes of student impact and teacher experience emerged. Social change implications may be possible through improved science education for students in this program. Agriculture science courses may be used to facilitate learning of complex science concepts, designing teacher collaboration and professional development for teaching science in a relevant context, and resultant improved student performance in science.

    Aneja, Viney P.; Blunden, Jessica; Roelle, Paul A.; Schlesinger, William H.; Knighton, Raymond; Niyogi, Dev; Gilliam, Wendell; Jennings, Greg; Duke, Clifford S.

    The first Workshop on Agricultural Air Quality: State of the Science was held at the Bolger Center in Potomac, Maryland from 4 to 8 June 2006. This international conference assembled approximately 350 people representing 25 nations from 5 continents, with disciplines ranging from atmospheric chemistry to soil science. The workshop was designed as an open forum in which participants could openly exchange the most current knowledge and learn about numerous international perspectives regarding agricultural air quality. Participants represented many stakeholder groups concerned with the growing need to assess agricultural impacts on the atmosphere and to develop beneficial policies to improve air quality. The workshop focused on identifying methods to improve emissions inventories and best management practices for agriculture. Workshop participants also made recommendations for technological and methodological improvements in current emissions measurement and modeling practices. The workshop commenced with a session on agricultural emissions and was followed by international perspectives from the United States, Europe, Australia, India, and South America. This paper summarizes the findings and issues of the workshop and articulates future research needs. These needs were identified in three general areas: (1) improvement of emissions measurement; (2) development of appropriate emission factors; and (3) implementation of best management practices (BMPs) to minimize negative environmental impacts. Improvements in the appropriate measurements will inform decisions regarding US farming practices. A need was demonstrated for a national/international network to monitor atmospheric emissions from agriculture and their subsequent depositions to surrounding areas. Information collected through such a program may be used to assess model performance and could be critical for evaluating any future regulatory policies or BMPs. The workshop concluded that efforts to maximize

    We review the current state of agricultural systems science, focusing in particular on the capabilities and limitations of agricultural systems models. We discuss the state of models relative to five different Use Cases spanning field, farm, landscape, regional, and global spatial scales and engaging questions in past, current, and future time periods. Contributions from multiple disciplines have made major advances relevant to a wide range of agricultural system model applications at various spatial and temporal scales. Although current agricultural systems models have features that are needed for the Use Cases, we found that all of them have limitations and need to be improved. We identified common limitations across all Use Cases, namely 1) a scarcity of data for developing, evaluating, and applying agricultural system models and 2) inadequate knowledge systems that effectively communicate model results to society. We argue that these limitations are greater obstacles to progress than gaps in conceptual theory or available methods for using system models. New initiatives on open data show promise for addressing the data problem, but there also needs to be a cultural change among agricultural researchers to ensure that data for addressing the range of Use Cases are available for future model improvements and applications. We conclude that multiple platforms and multiple models are needed for model applications for different purposes. The Use Cases provide a useful framework for considering capabilities and limitations of existing models and data.

    2008-09-01

    During recent months, another sign of the global fragility to sustain the increasing human demand for resources has appeared with merciless cruelty. Increasing food prices, paradoxically driven to a large extent by the rapid economic growth of vast regions of the emerging world, are affecting hundreds of millions of the poorest people in Africa, Asia, and Latin America. As described in Science for Agriculture and Rural Development in Low-Income Countries, most of the poorest people in these low-income countries live in rural areas and are engaged in agriculture or related activities. Because many people in these areas are engaged in subsistence agriculture, they do not share in the added income derived from higher market prices for food.

    Agricultural systems science generates knowledge that allows researchers to consider complex problems or take informed agricultural decisions. The rich history of this science exemplifies the diversity of systems and scales over which they operate and have been studied. Modeling, an essential tool in agricultural systems science, has been accomplished by scientists from a wide range of disciplines, who have contributed concepts and tools over more than six decades. As agricultural scientists now consider the next generation models, data, and knowledge products needed to meet the increasingly complex systems problems faced by society, it is important to take stock of this history and its lessons to ensure that we avoid re-invention and strive to consider all dimensions of associated challenges. To this end, we summarize here the history of agricultural systems modeling and identify lessons learned that can help guide the design and development of next generation of agricultural system tools and methods. A number of past events combined with overall technological progress in other fields have strongly contributed to the evolution of agricultural system modeling, including development of process-based bio-physical models of crops and livestock, statistical models based on historical observations, and economic optimization and simulation models at household and regional to global scales. Characteristics of agricultural systems models have varied widely depending on the systems involved, their scales, and the wide range of purposes that motivated their development and use by researchers in different disciplines. Recent trends in broader collaboration across institutions, across disciplines, and between the public and private sectors suggest that the stage is set for the major advances in agricultural systems science that are needed for the next generation of models, databases, knowledge products and decision support systems.

  12. In pursuit of a science of agriculture: the role of statistics in field experiments.

    PubMed

    Parolini, Giuditta

    2015-09-01

    Since the beginning of the twentieth century statistics has reshaped the experimental cultures of agricultural research taking part in the subtle dialectic between the epistemic and the material that is proper to experimental systems. This transformation has become especially relevant in field trials and the paper will examine the British agricultural institution, Rothamsted Experimental Station, where statistical methods nowadays popular in the planning and analysis of field experiments were developed in the 1920s. At Rothamsted statistics promoted randomisation over systematic arrangements, factorisation over one-question trials, and emphasised the importance of the experimental error in assessing field trials. These changes in methodology transformed also the material culture of agricultural science, and a new body, the Field Plots Committee, was created to manage the field research of the agricultural institution. Although successful, the vision of field experimentation proposed by the Rothamsted statisticians was not unproblematic. Experimental scientists closely linked to the farming community questioned it in favour of a field research that could be more easily understood by farmers. The clash between the two agendas reveals how the role attributed to statistics in field experimentation defined different pursuits of agricultural research, alternately conceived of as a scientists' science or as a farmers' science.

  13. Science at Hampton Normal and Agricultural Institute, 1868-1893

    NASA Astrophysics Data System (ADS)

    Tucker, Linda Bart

    Science had a variety of uses at Hampton Normal and Agricultural Institute, a private, missionary school supported by northern whites and Virginia's black land grant school from 1872 to 1920. Samuel Chapman Armstrong, principal for the first twenty-five years (1868-1893), advocated not classical but scientific studies, primarily as applied science to improve lives and "civilize" blacks and Indians. Agriculture and mechanics were practiced in Hampton's industries, where students worked their way through school. They were organized for production rather than instruction, though Armstrong claimed that labor had a moral value and that practical experience was valuable learning. In contrast to works by James D. Anderson and Donald Spivey, this study stresses the pragmatic, business purposes of Hampton's industries rather than any ideological agenda. Problems with providing specialized facilities, apparatus, and teachers made it difficult for Hampton to provide rigorous, graded science instruction. Students learned of practical applications of science in agricultural lectures and in such classes as physiology. However, the curriculum was designed for teacher training, using broad, elementary science for general knowledge, to train minds, and to make adult remedial language lessons more effective. Not surprisingly, very few graduates pursued careers which required more than general science studies. Besides the utilitarian and disciplinary purposes, Hampton used science to discourage superstitious ideas in religion. Armstrong also argued for racially distinctive education for blacks and Indians on the basis of scientific ideas about cultural evolution and inheritance of the experience of past generations. In practice, however, Hampton teachers adapted mainstream tools and methods of instruction. Not all teachers shared Armstrong's racial views, and several demonstrated concern for students, confidence in their ability, and professional interest in advancing them as

    Agricultural productivity is expected to be sensitive to global climate change. Models from atmospheric science, plant science, and agricultural economics are linked to explore this sensitivity. Although the results depend on the severity of climate change and the compensating effects of carbon dioxide on crop yields, the simulation suggests that irrigated acreage will expand and regional patterns of U.S. agriculture will shift. The impact of the U.S. economy strongly depends on which climate model is used.

    PubMed

    Hersey, Mark D

    2011-01-01

    Though they are often seen as foils for each other, ecology and agricultural science co-evolved. With shared roots in late nineteenth-century botany, ecologists and agronomists fostered important connections during the Progressive era that have been largely overlooked despite a number of finely nuanced studies of ecology's origins. But if 'applied ecology' once effectively meant agriculture, over the course of the first decades of the twentieth century the relationship between ecology and scientific agriculture grew strained. Agriculturists narrowed their focus to increasing yields, and ecologists sought to establish their discipline as a distant theoretical science and so distanced themselves from its agricultural applications. By the end of World War I, the process of disciplinary specialization was well underway. In time, the two disciplines diverged so completely that the once vital connections between them were obscured and forgotten.

    2013-12-01

    This essay explores the participation of Latin America and the Caribbean in the construction and circulation of tropical agricultural science during the nineteenth century and the first half of the twentieth century. It uses the term "islands of knowledge" to underscore the idea that each producing region across the global tropics, including Latin America and the Caribbean, was instrumental in the creation, adoption, and application of scientific procedures. At the same time, it emphasizes the value of interchange and interconnection between these regions, as well as the many and heterogeneous local areas, for analyzing what it calls "global archipelago agricultural scientific knowledge." This focus challenges the traditional center/periphery hierarchy and opens it to a wider vision of science and practice in agriculture. This essay shows how writing in related areas of research--specifically, commodity histories, biological exchange studies, and knowledge exchange studies--introduces approaches and case studies that are useful for the history of tropical agricultural science. In particular, this work provides analytical frameworks for developing studies of exchanges across the Global South.

  13. Starting a learning progression for agricultural literacy: A qualitative study of urban elementary student understandings of agricultural and science education benchmarks

    NASA Astrophysics Data System (ADS)

    Hess, Alexander Jay

    Science and agriculture professional organizations have argued for agricultural literacy as a goal for K-12 public education. Due to the complexity of our modern agri-food system, with social, economic, and environmental concerns embedded, an agriculturally literate society is needed for informed decision making, democratic participation, and system reform. While grade-span specific benchmarks for gauging agri-food system literacy have been developed, little attention has been paid to existing ideas individuals hold about the agri-food system, how these existing ideas relate to benchmarks, how experience shapes such ideas, or how ideas change overtime. Developing a body of knowledge on students' agri-food system understandings as they develop across K-12 grades can ground efforts seeking to promote a learning progression toward agricultural literacy. This study compares existing perceptions held by 18 upper elementary students from a large urban center in California to agri-food system literacy benchmarks and examines the perceptions against student background and experiences. Data were collected via semi-structured interviews and analyzed using the constant comparative method. Constructivist theoretical perspectives framed the study. No student had ever grown their own food, raised a plant, or cared for an animal. Participation in school fieldtrips to farms or visits to a relative's garden were agricultural experiences most frequently mentioned. Students were able to identify common food items, but could not elaborate on their origins, especially those that were highly processed. Students' understanding of post-production activities (i.e. food processing, manufacturing, or food marketing) was not apparent. Students' understanding of farms reflected a 1900's subsistence farming operation commonly found in a literature written for the primary grades. Students were unaware that plants and animals were selected for production based on desired genetic traits. Obtaining

    We present an overview of USDA Agricultural Research Service (ARS) computer models and databases related to pest-management science, emphasizing current developments in environmental risk assessment and management simulation models. The ARS has a unique national interdisciplinary team of researchers in surface and sub-surface hydrology, soil and plant science, systems analysis and pesticide science, who have networked to develop empirical and mechanistic computer models describing the behavior of pests, pest responses to controls and the environmental impact of pest-control methods. Historically, much of this work has been in support of production agriculture and in support of the conservation programs of our 'action agency' sister, the Natural Resources Conservation Service (formerly the Soil Conservation Service). Because we are a public agency, our software/database products are generally offered without cost, unless they are developed in cooperation with a private-sector cooperator. Because ARS is a basic and applied research organization, with development of new science as our highest priority, these products tend to be offered on an 'as-is' basis with limited user support except for cooperating R&D relationship with other scientists. However, rapid changes in the technology for information analysis and communication continually challenge our way of doing business.

    The ecological agriculture of traditional Chinese medicine (TCM) is generally acknowledged as the most advanced agricultural mode. However, it's still a doubt whether ecological agriculture could be widely applied in TCM agriculture. In this study, we first analyze both the differences and relationships between ecological and organic agriculture, which suggesting that ecological agriculture does not need all the inputs as traditional agriculture. After introducing the situation of ecological agriculture from all across the world, we analyze the differences and characteristics between ecological and chemical agricultures. Considered with the big challenge caused by chemical agriculture, we pointed out that ecological agriculture could definitely replace chemical agriculture. Last but not the least, combined with the situation and problems of Chinese agriculture, we analyze the distinctive advantages of TCM ecological agriculture from 3 aspects as its unique quality characteristics, its unique habitat requirements in production and its unique application and market characteristics, respectively. In conclusion, ecological agriculture is the straight way of TCM agriculture. Copyright© by the Chinese Pharmaceutical Association.

  1. Virus-Bacteria Interactions: Implications and Potential for the Applied and Agricultural Sciences.

    PubMed

    Moore, Matthew D; Jaykus, Lee-Ann

    2018-02-02

    Eukaryotic virus-bacteria interactions have recently become an emerging topic of study due to multiple significant examples related to human pathogens of clinical interest. However, such omnipresent and likely important interactions for viruses and bacteria relevant to the applied and agricultural sciences have not been reviewed or compiled. The fundamental basis of this review is that these interactions have importance and deserve more investigation, as numerous potential consequences and applications arising from their discovery are relevant to the applied sciences. The purpose of this review is to highlight and summarize eukaryotic virus-bacteria findings in the food/water, horticultural, and animal sciences. In many cases in the agricultural sciences, mechanistic understandings of the effects of virus-bacteria interactions remain unstudied, and many studies solely focus on co-infections of bacterial and viral pathogens. Given recent findings relative to human viral pathogens, further research related to virus-bacteria interactions would likely result in numerous discoveries and beneficial applications.

    As Earth's climate warms, agricultural producers will need to adapt. Changes, especially increases in extreme events, are already having an impact on food production, according to speakers at a 1 May session on agriculture and food security at the AGU Science Policy Conference. Christopher Field, director of the Department of Global Ecology at the Carnegie Institution for Science of Washington, D. C., pointed out the complex factors that come into play in understanding food security, including spatially varying controls and stresses, incomplete models, and the potential for threshold responses. Factors that are likely to cause problems include increasing population; increasing preference for meat, which needs more land and energy inputs to produce; climate change; and increasing use of agricultural lands for biomass energy.

  4. Reflections on the reproductive sciences in agriculture in the UK and US, ca. 1900-2000+.

    PubMed

    Clarke, Adele E

    2007-06-01

    This paper provides a brief comparative overview of the development of the reproductive sciences especially in agriculture in the UK and the US. It begins with the establishment by F. H. A. Marshall in 1910 of the boundaries that framed the reproductive sciences as distinct from genetics and embryology. It then examines how and where the reproductive sciences were taken up in agricultural research settings, focusing on the differential development of US and UK institutions. The reproductive sciences were also pursued in medical and biological settings, and I discuss how the intersections among all three allowed the circulation of both ideas and scientists' careers. Across the twentieth century, scientific leadership in the reproductive sciences alternated between the UK and US, and these patterns are elucidated. I conclude with thoughts on future research that might emphasize the elaboration of industrialization processes in agriculture and new capacities to transform both reproductive processes and their products--life itself--as biopower comes to be more ambitiously understood as extending across all species.

    Joyce, Alexander Augusto

    The purpose of this study was to assess the inclusion of a Natuculture systems learning experience into selected high school STEM courses to determine high school students' interests in majoring in STEM and for pursuing careers in agricultural sciences. Natuculture is defined as "any human-made system that mimics nature in human-disturbed landscapes". The research occurred at an urban area high school located in the Piedmont region of North Carolina. Fifty-three students in grades 9-12 participated during an academic semester learning experience which included planting, maintenance, & harvesting for an oasissofa. Data was collected using a questionnaire and reflective journals to gather students' attitudes towards agriculture and science and knowledge towards agriculture. Results showed that while the experiences did not improve students' interest in pursuing careers in agricultural sciences, overall, they did increase their knowledge of concepts related to agriculture. It was concluded that students benefit from experiential learning experiences. Based on the study, it is recommended that future research follow up with students to learn of their educational and career choices in agriculture and future learning experiences include curricula that integrates agricultural topics with STEM courses.

    Monitoring global agricultural crop conditions during the growing season and estimating potential seasonal production are critically important for market development of U.S. agricultural products and for global food security. Two major operational users of satellite remote sensing for global crop monitoring are the USDA Foreign Agricultural Service (FAS) and the U.N. World Food Programme (WFP). The primary goal of FAS is to improve foreign market access for U.S. agricultural products. The WFP uses food to meet emergency needs and to support economic and social development. Both use global agricultural decision support systems that can integrate and synthesize a variety of data sources to provide accurate and timely information on global crop conditions. The Goddard Space Flight Center Earth Sciences Distributed Active Archive Center (GES DAAC) has begun a project to provide operational solutions to FAS and WFP, by fully leveraging results from previous work, as well as from existing capabilities of the users. The GES DAAC has effectively used its recently developed prototype TRMM Online Visualization and Analysis System (TOVAS) to provide ESE data and information to the WFP for its agricultural drought monitoring efforts. This prototype system will be evolved into an Agricultural Information System (AIS), which will operationally provide ESE and other data products (e.g., rainfall, land productivity) and services, to be integrated into and thus enhance the existing GIS-based, decision support systems of FAS and WFP. Agriculture-oriented, ESE data products (e.g., MODIS-based, crop condition assessment product; TRMM derived, drought index product) will be input to a crop growth model in collaboration with the USDA Agricultural Research Service, to generate crop condition and yield prediction maps. The AIS will have the capability for remotely accessing distributed data, by being compliant with community-based interoperability standards, enabling easy access to

  1. Changes in agricultural carbon emissions and factors that influence agricultural carbon emissions based on different stages in Xinjiang, China.

    PubMed

    Xiong, Chuanhe; Yang, Degang; Xia, Fuqiang; Huo, Jinwei

    2016-11-10

    Xinjiang's agricultural carbon emissions showed three stages of change, i.e., continued to rise, declined and continued to rise, during 1991-2014. The agriculture belonged to the "low emissions and high efficiency" agriculture category, with a lower agricultural carbon emission intensity. By using the logarithmic mean divisia index decomposition method, agricultural carbon emissions were decomposed into an efficiency factor, a structure factor, an economy factor, and a labour factor. We divided the study period into five stages based on the changes in efficiency factor and economy factor. Xinjiang showed different agricultural carbon emission characteristics at different stages. The degree of impact on agricultural carbon emissions at these stages depended on the combined effect of planting-animal husbandry carbon intensity and agricultural labour productivity. The economy factor was the critical factor to promote the increase in agricultural carbon emissions, while the main inhibiting factor for agricultural carbon emissions was the efficiency factor. The labour factor became more and more obvious in increasing agricultural carbon emissions. Finally, we discuss policy recommendations in terms of the main factors, including the development of agricultural science and technology (S&T), the establishment of three major mechanisms and transfer of rural labour in ethnic areas.

    The National Institute of Food and Agriculture within the U.S. Department of Agriculture provides leadership, capacity, and funds to support the continuing development of a safe and competitive agricultural system. Many of the agency's educational programs are led by the Division of Community and Education (DOCE). These programs span agricultural education, enhancing agricultural literacy through both formal and nonformal education. Here, we have highlighted funding opportunities within DOCE that enhance agricultural education and literacy by supporting the improvement of students' critical communication, leadership skills, and experiential learning opportunities. Some of these programs include opportunities for which students can apply, while others focus on faculty applications. Opportunities faculty can apply for may support student-recruitment and student-retention techniques, curriculum development, innovative teaching methods, and institutional capacity-building programs. Overall, these programs foster a diverse workforce in agricultural science that matches the increasing diversity of the country. © 2016 J. E. Parker and D. J. Wagner.

  20. Science, technique, technology: passages between matter and knowledge in imperial Chinese agriculture.

    PubMed

    Bray, Francesca

    2008-09-01

    Many historians today prefer to speak of knowledge and practice rather than science and technology. Here I argue for the value of reinstating the terms science, techniques and technology as tools for a more precise analysis of governmentality and the workings of power. My tactic is to use these three categories and their articulations to highlight flows between matter and ideas in the production and reproduction of knowledge. In any society, agriculture offers a wonderfully rich case of how ideas, material goods and social relations interweave. In China agronomy was a science of state, the basis of legitimate rule. I compare different genres of agronomic treatise to highlight what officials, landowners and peasants respectively contributed to, and expected from, this charged natural knowledge. I ask how new forms of textual and graphic inscription for encoding agronomic knowledge facilitated its dissemination and ask how successful this knowledge proved when rematerialized and tested as concrete artefacts or techniques. I highlight forms of innovation in response to crisis, and outline the overlapping interpretative frameworks within which the material applications of Chinese agricultural science confirmed and extended its truth across space and time.

  1. [Effects of agricultural activities and transgenic crops on agricultural biodiversity].

    2014-09-01

    Agricultural biodiversity is a key part of the ecosystem biodiversity, but it receives little concern. The monoculture, environmental pollution and habitat fragmentation caused by agricultural activities have threatened agricultural biodiversity over the past 50 years. To optimize agricultural management measures for crop production and environmental protection, we reviewed the effects of agricultural activities, including cultivation patterns, plastic mulching, chemical additions and the cultivation of transgenic crops, on agricultural biodiversity. The results showed that chemical pesticides and fertilizers had the most serious influence and the effects of transgenic crops varied with other factors like the specific transgene inserted in crops. The environmental risk of transgenic crops should be assessed widely through case-by-case methods, particularly its potential impacts on agricultural biodiversity. It is important to consider the protection of agricultural biodiversity before taking certain agricultural practices, which could improve agricultural production and simultaneously reduce the environmental impacts.

    The National Institute of Food and Agriculture within the U.S. Department of Agriculture provides leadership, capacity, and funds to support the continuing development of a safe and competitive agricultural system. Many of the agency’s educational programs are led by the Division of Community and Education (DOCE). These programs span agricultural education, enhancing agricultural literacy through both formal and nonformal education. Here, we have highlighted funding opportunities within DOCE that enhance agricultural education and literacy by supporting the improvement of students’ critical communication, leadership skills, and experiential learning opportunities. Some of these programs include opportunities for which students can apply, while others focus on faculty applications. Opportunities faculty can apply for may support student-recruitment and student-retention techniques, curriculum development, innovative teaching methods, and institutional capacity-building programs. Overall, these programs foster a diverse workforce in agricultural science that matches the increasing diversity of the country. PMID:27587851

    2018-02-01

    In agricultural and natural systems researchers have demonstrated large effects of plant-soil feedback (PSF) on plant growth. However, the concepts and approaches used in these two types of systems have developed, for the most part, independently. Here, we present a conceptual framework that integrates knowledge and approaches from these two contrasting systems. We use this integrated framework to demonstrate (i) how knowledge from complex natural systems can be used to increase agricultural resource-use efficiency and productivity and (ii) how research in agricultural systems can be used to test hypotheses and approaches developed in natural systems. Using this framework, we discuss avenues for new research toward an ecologically sustainable and climate-smart future. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Since the beginning of the 2000s, it has been conducted many projects such as Agricultural Sector Integrated Management Information System, Agriculture Information System, Agricultural Production Registry System and Farmer Registry System by the Turkish Ministry of Food, Agriculture and Livestock and the Turkish Statistical Institute in order to establish and manage better agricultural policy and produce better agricultural statistics in Turkey. Yet, it has not been carried out any study for the structuring of a system which can meet the requirements of different institutions and organizations that need similar agricultural data. It has been tried to meet required data only within the frame of the legal regulations from present systems. Whereas the developments in GIS (Geographical Information Systems) and standardization, and Turkey National GIS enterprise in this context necessitate to meet the demands of organizations that use the similar data commonly and to act in terms of a data model logic. In this study, 38 institutions or organization which produce and use agricultural data were detected, that and thanks to survey and interviews undertaken, their needs were tried to be determined. In this study which is financially supported by TUBITAK, it was worked out relationship between farmer, agricultural land and agricultural production data and all of the institutions and organizations in Turkey and in this context, it was worked upon the best detailed and effective possible data model. In the model design, UML which provides object-oriented design was used. In the data model, for the management of spatial data, sub-parcel data model was used. Thanks to this data model, declared and undeclared areas can be detected spatially, and thus declarations can be associated to sub-parcels. Within this framework, it will be able to developed agricultural policies as a result of acquiring more extensive, accurate, spatially manageable and easily updatable farmer and

    As global populations continue to increase, agricultural productivity will be challenged to keep pace without overtaxing important environmental resources. A dynamic and integrated approach will be required to solve global food insecurity and position agriculture on a trajectory toward sustainability. Genetically modified (GM) crops enhanced through modern biotechnology represent an important set of tools that can promote sustainable agriculture and improve food security. Several emerging biotechnology approaches were discussed in a recent symposium organized at the 13th IUPAC International Congress of Pesticide Chemistry meeting in San Francisco, CA, USA. This paper summarizes the innovative research and several of the new and emerging technologies within the field of agricultural biotechnology that were presented during the symposium. This discussion highlights how agricultural biotechnology fits within the context of sustainable agriculture and improved food security and can be used in support of further development and adoption of beneficial GM crops.

  11. Anthropology in Agricultural Health and Safety Research and Intervention.

    PubMed

    Arcury, Thomas

    2017-01-01

    Agriculture remains a dangerous industry, even as agricultural science and technology continue to advance. Research that goes beyond technological changes to address safety culture and policy are needed to improve health and safety in agriculture. In this commentary, I consider the potential for anthropology to contribute to agricultural health and safety research by addressing three aims: (1) I briefly consider what the articles in this issue of the Journal of Agromedicine say about anthropologists in agricultural health and safety; (2) I discuss what anthropologists can add to agricultural health and safety research; and (3) I examine ways in which anthropologists can participate in agricultural health and safety research. In using their traditions of rigorous field research to understand how those working in agriculture perceive and interpret factors affecting occupational health and safety (their "emic" perspective), and translating this perspective to improve the understanding of occupational health professionals and policy makers (an "etic" perspective), anthropologists can expose myths that limit improvements in agricultural health and safety. Addressing significant questions, working with the most vulnerable agricultural communities, and being outside establishment agriculture provide anthropologists with the opportunity to improve health and safety policy and regulation in agriculture.

  16. "Othering" agricultural biotechnology: Slovenian media representation of agricultural biotechnology.

    PubMed

    Zajc, Jožica; Erjavec, Karmen

    2014-08-01

    While studies on media representations of agricultural biotechnology mostly analyse media texts, this work is intended to fill a research gap with an analysis of journalistic interpretations of media representations. The purpose of this project was to determine how news media represent agricultural biotechnology and how journalists interpret their own representations. A content and critical discourse analysis of news texts published in the Slovenian media over two years and in-depth interviews with their authors were conducted. News texts results suggest that most of the news posts were "othering" biotechnology and biotechnologists: biotechnology as a science and individual scientists are represented as "they," who are socially irresponsible, ignorant, arrogant, and "our" enemies who produce unnatural processes and work for biotechnology companies, whose greed is destroying people, animals, and the environment. Most journalists consider these representations to be objective because they have published the biotechnologists' opinions, despite their own negative attitudes towards biotechnology.

    The global and regional potentials of Earth Observation (EO) to contribute to food security and sustainable agriculture in the 2050-timeframe were analysed in the ESA study EO4Food, whose outcome will be presented (www.EO4Food.org). Emphasis was put on the global societal, economic, environmental and technological megatrends that will create demand for food and shape the future societies. They will also constitute the background for developments in EO for food security and sustainable agriculture. The capabilities of EO in this respect were critically reviewed with three perspectives 1) the role of EO science for society, 2) observables from space and 3) development of future science missions.It was concluded that EO can be pivotal for the further development of food security and sustainable agriculture. EO allows to support the whole economic and societal value chain from farmers through food industry to insurance and financial industry in satisfying demands and at the same time to support society in governing sustainable agriculture through verifyable rules and regulations. It has the potential to become the global source of environmental information that is assimilated into sophisticated environmental management models and is used to make agriculture sustainable.

  19. [Towards a renewable and sustainable agriculture. Biological agriculture: from marginal vanguard to spearhead of the agriculture of the future].

    PubMed

    Diek Van Mansvelt, J

    1992-01-01

    This work seeks to demonstrate how different types of organic agriculture can meet the need for renewable and sustainable agriculture, rural development, and management of the land and water resources. An obstacle to the spread of organic agriculture is the widespread perception that without intensive factors of production, demographic growth will necessarily outstrip the available food resources. Calculation of economic costs and benefits at present carries greater weight in planning than do soil erosion, deforestation, extinction of species, disappearance of habitats, and similar environmental damage. The different types of organic agriculture do not follow rigid rules and are not defined solely by the nonuse of nitrogenous fertilizers and pesticides. One of the main principles or organic agriculture is to respect local soil and climatic conditions. Self-sufficiency regarding external factors of production and an emphasis on recycling and optimal use of natural resources were concept ahead of their time when they initially were introduced in the 1920s. The specialization which restructured agriculture over the past century has seriously damaged the system of mixed agriculture and the chain of food production. The solution will be to seek for each region an appropriate balance linking animals and agricultural production in an organic process. The objective of organic agriculture, also known as autonomous ecosystem management, is to preserve as far as possible the balance between needs for food and fiber on the 1 hand and the potential of local ecosystems on the other. General principles of organic agriculture include mixed exploitation in which both plants and animals have specific functions in the context of their local soil and climatic characteristics. Different types of crop rotation are practiced to optimize mutual interactions between crops, and the varied organic cycles are also optimized within the framework of anorganic management in accord with nature

    characterise the surface morphology. For each of derived Digital Elevation Model, seven morphometric indexes, such as slope, curvature, flow direction, contributing area, roughness, and connectivity was calculated. We showed then the variations of the morphology in the areas converted to the conservation agriculture, and, consequently, a possible modification of processes such as erosion and runoff. The results suggested that the agricultural surfaces interested by no-tillage practices are different from those tilled with conventional systems. The topography is rougher, with chaotic flow directions, and more concave areas, thus resulting in potential water storages, mitigating the intensity of soil erosion and runoff processes. On the other hand, the topography of traditional tillage area is more regular and smooth, with flow directions that tend to follow the same direction on the surface. These results are a novelty in the Earth Science and Agronomy: we demonstrated and quantified, from the geomorphological point of view, the potential role of conservative agriculture in mitigating, not only land degradation phenomena, but also the distribution of pollutants, and rainfall-runoff processes.

And on this basis, we analyzed the background and current situation of eco-agriculture of Chinese materia medica, and proposed its development ideas and key tasks, including: (1) Analysis and planning of the production pattern of Chinese material medica national wide. (2) Typical features extraction of regional agriculture of Chinese materia medica. (3) Investigation of the interaction and its mechanism between typical Chinese materia medica in each region and the micro-ecology of rhizosphere soil. (4) Study on technology of eco-agriculture of Chinese materia medica. (5) Extraction and solidification of eco-agriculture modes of Chinese materia medica. (6) Study on the theory of eco-agriculture of Chinese materia medica. Also we pointed out that GAP and eco-agriculture of Chinese material medica are both different and relative, but they are not contradictory with their own features. It is an irresistible trend to promote eco-agriculture in the GAP of Chinese material medica and coordinate ecological and economic development.

    Reed, Deborah B; Kidd, Pamela S

    2004-01-01

    Nearly 2 million children live or work on America's farms and ranches. Despite the increasing mechanization of production agriculture in the United States, children still constitute a considerable portion of the work force on farms and ranches. When adjusted for actual work exposure time, adolescent injury rates on agricultural establishments surpass those of adults (Castillo, D. N., Landen, D. D., & Layne, L. A. (1994). American Journal of Public Health, 84, 646-649). This project, headed by two public health nurses, developed and tested an agricultural safety curriculum [Agricultural Disability Awareness and Risk Education (AgDARE)] for use in high school agriculture classes. Students who participated in AgDARE scored significantly higher in farm safety attitude and intent to change work behavior than the control group. School and public health nurses, working together with agriculture teachers, may make an effective team in reducing injuries among teen agricultural workers.

  16. Beyond knowledge transfer: The social construction of autonomous academic science in university-industry agricultural biotechnology research collaborations

    NASA Astrophysics Data System (ADS)

    Biscotti, Dina Louise

    Autonomy is a social product. Although some might view autonomy as the absence of social interference in individual action, it is in fact produced through social institutions. It enables social actors to act; it is the justification for the allocation of enormous public resources into institutions classified as "public" or "nonprofit;" it can lead to innovation; and, significantly, it is key to the public acceptance of new technologies. In this dissertation, I analyze the social construction of autonomy for academic science in U.S. university-industry agricultural biotechnology research collaborations. University-industry relationships (UIRs) are a site of concern about the influence of commercial interests on academic science. Agricultural biotechnology is a contentious technology that has prompted questions about the ecological and public health implications of genetically-modified plants and animals. It has also spurred awareness of the industrialization of agriculture and accelerating corporate control of the global food system. Through analysis of in-depth interviews with over 200 scientists and administrators from nine U.S. research universities and thirty agricultural biotechnology companies, I find that both the academy and industry have a vested interest in the social construction of the academy as an autonomous space from which claims to objective, disinterested scientific knowledge can be made. These claims influence government regulation, as well as grower and public acceptance of agricultural biotechnology products. I argue that the social production of autonomy for academic science can be observed in narratives and practices related to: (1) the framing of when, how and why academic scientists collaborate with industry, (2) the meanings ascribed to and the uses deemed appropriate for industry monies in academic research, and (3) the dissemination of research results into the public domain through publications and patents. These narratives and practices

    Using pesticides has double effects. On one hand, it contributes to pests control and regulates the growth of crops; On the other hand, it does harm to the environment. To develop ecological agriculture should not only emphasize the output level of agriculture to pursuit of economic efficiency, but also need to keep the ecological environment protected and focus on the social benefits during the development of the industry. As a large agricultural country in the world, China is vigorously promoting the development of ecological agriculture, which is bound to put forward to developing the pesticide industry and green ecological development requirements to promote the transformation and upgrading of agricultural pharmaceutical industry. This paper discusses the mechanism of pesticide pollution on the ecological environment and analyzes China's agricultural problems in the pharmaceutical industry. Then study on the development of Chinese green pesticides and try to find the proper paths of agricultural pharmaceutical to achieve industrial upgrading.

  8. Environmental challenges threatening the growth of urban agriculture in the United States.

    PubMed

    Wortman, Sam E; Lovell, Sarah Taylor

    2013-09-01

    Urban agriculture, though often difficult to define, is an emerging sector of local food economies in the United States. Although urban and agricultural landscapes are often integrated in countries around the world, the establishment of mid- to large-scale food production in the U.S. urban ecosystem is a relatively new development. Many of the urban agricultural projects in the United States have emerged from social movements and nonprofit organizations focused on urban renewal, education, job training, community development, and sustainability initiatives. Although these social initiatives have traction, critical knowledge gaps exist regarding the science of food production in urban ecosystems. Developing a science-based approach to urban agriculture is essential to the economic and environmental sustainability of the movement. This paper reviews abiotic environmental factors influencing urban cropping systems, including soil contamination and remediation; atmospheric pollutants and altered climatic conditions; and water management, sources, and safety. This review paper seeks to characterize the limited state of the science on urban agricultural systems and identify future research questions most relevant to urban farmers, land-use planners, and environmental consultants.

    Kadiyala, Suneetha; Harris, Jody; Headey, Derek; Yosef, Sivan; Gillespie, Stuart

    2014-12-01

    In India, progress against undernutrition has been slow. Given its importance for income generation, improving diets, care practices, and maternal health, the agriculture sector is widely regarded as playing an important role in accelerating the reduction in undernutrition. This paper comprehensively maps existing evidence along agriculture-nutrition pathways in India and assesses both the quality and coverage of the existing literature. We present a conceptual framework delineating six key pathways between agriculture and nutrition. Three pathways pertain to the nutritional impacts of farm production, farm incomes, and food prices. The other three pertain to agriculture-gender linkages. After an extensive search, we found 78 research papers that provided evidence to populate these pathways. The literature suggests that Indian agriculture has a range of important influences on nutrition. Agriculture seems to influence diets even when controlling for income, and relative food prices could partly explain observed dietary changes in recent decades. The evidence on agriculture-gender linkages to nutrition is relatively weak. Sizeable knowledge gaps remain. The root causes of these gaps include an interdisciplinary disconnect between nutrition and economics/agriculture, a related problem of inadequate survey data, and limited policy-driven experimentation. Closing these gaps is essential to strengthening the agriculture sector's contribution to reducing undernutrition. © 2014 New York Academy of Sciences.

  20. Paths of convergence for agriculture, health, and wealth.

    PubMed

    Dubé, Laurette; Pingali, Prabhu; Webb, Patrick

    2012-07-31

    This special feature calls for forward thinking around paths of convergence for agriculture, health, and wealth. Such convergence aims for a richer integration of smallholder farmers into national and global agricultural and food systems, health systems, value chains, and markets. The articles identify analytical innovation, where disciplines intersect, and cross-sectoral action where single, linear, and siloed approaches have traditionally dominated. The issues addressed are framed by three main themes: (i) lessons related to agricultural and food market growth since the 1960s; (ii) experiences related to the integration of smallholder agriculture into national and global business agendas; and (iii) insights into convergence-building institutional design and policy, including a review of complexity science methods that can inform such processes. In this introductory article, we first discuss the perspectives generated for more impactful policy and action when these three themes converge. We then push thematic boundaries to elaborate a roadmap for a broader, solution-oriented, and transdisciplinary approach to science, policies, and actions. As the global urban population crosses the 50% mark, both smallholder and nonsmallholder agriculture are keys in forging rural-urban links, where both farm and nonfarm activities contribute to sustainable nutrition security. The roadmaps would harness the power of business to reduce hunger and poverty for millions of families, contribute to a better alignment between human biology and modern lifestyles, and stem the spread of noncommunicable chronic diseases.

    Pearson, Camilla E.

    Little is known about the concerns and needs of early career agricultural teachers associated with the various routes to certification and how these routes address those concerns. The purpose of this study is to determine how selected early career agriculture teachers perceive their teacher preparation program and how effective their programs were at addressing these concerns during their first year of teaching. The sample consisted of secondary agricultural teachers in Texas FFA Areas V and VI, who self-identified themselves as an early career agricultural teacher in their first 3 years of teaching. The first phase included a web-based survey administered to assess the concerns of early career agricultural teachers. Two Likert-type scales were used, and these were used to assess the perceived importance of problems faced by early career agricultural teachers and the frequency in which they encounter those problems. The second phase included a qualitative interview to better understand the perceived relationship between participants' undergraduate preparation, experiences in agriculture and related organizations, and other related activities in preparing them as agriculture science teachers. The teachers interviewed in this study indicated that overall, they were pleased with their preparation. Teacher educators from both programs should address the concerns presented from all teachers to further prepare them for issues faced by early career teachers because it is evident that these issues are not going away.

    Precision animal agriculture is poised to rise to prominence in the livestock enterprise in the domains of management, production, welfare, sustainability, health surveillance, and environmental footprint. Considerable progress has been made in the use of tools to routinely monitor and collect information from animals and farms in a less laborious manner than before. These efforts have enabled the animal sciences to embark on information technology-driven discoveries to improve animal agriculture. However, the growing amount and complexity of data generated by fully automated, high-throughput data recording or phenotyping platforms, including digital images, sensor and sound data, unmanned systems, and information obtained from real-time noninvasive computer vision, pose challenges to the successful implementation of precision animal agriculture. The emerging fields of machine learning and data mining are expected to be instrumental in helping meet the daunting challenges facing global agriculture. Yet, their impact and potential in "big data" analysis have not been adequately appreciated in the animal science community, where this recognition has remained only fragmentary. To address such knowledge gaps, this article outlines a framework for machine learning and data mining and offers a glimpse into how they can be applied to solve pressing problems in animal sciences.

    Science and innovation are important components underpinning the agricultural and agri-food system in Canada. Canada's vast geographical area presents diverse, regionally specific requirements in addition to the 21st century agricultural challenges facing the overall sector. As the broader needs of the agricultural landscape have evolved and will continue to do so in the next few decades, there is a trend in place to transition towards a sustainable bioeconomy, contributing to reducing greenhouse gas emission and our dependency on non-renewable resources. We highlight some of the key policy drivers on an overarching national scale and those specific to agricultural research and innovation that are critical to fostering a supportive environment for innovation and a sustainable bioeconomy. As well, we delineate some major challenges and opportunities facing agriculture in Canada, including climate change, sustainable agriculture, clean technologies, and agricultural productivity, and some scientific initiatives currently underway to tackle these challenges. The use of various technologies and scientific efforts, such as Next Generation Sequencing, metagenomics analysis, satellite image analysis and mapping of soil moisture, and value-added bioproduct development will accelerate scientific development and innovation and its contribution to a sustainable and prosperous bioeconomy.

  19. Preparing students for higher education and careers in agriculture and related fields: An ethnography of an urban charter school

    NASA Astrophysics Data System (ADS)

    Henry, Kesha Atasha

    This study explored the preparation of students for higher education and careers in agriculturally-related fields at an urban charter high school. The data were collected through interviews, observations, and field notes. The data were analyzed by qualitative methodology with phenomenology as the theoretical framework. Findings indicated that administrators thought it was important to incorporate agricultural science courses into urban school curricula. They stated that agricultural science courses gave urban students a different way of looking at science and helped to enhance the science and technology focus of the school. Further, agricultural science courses helped to break urban students' stereotypes about agriculture and helped to bring in more state funding for educational programs. However they thought that it was more challenging to teach agricultural science in urban versus rural schools and they focused more on Science, Technology, Engineering, and Mathematics (STEM) related careers. The students had mixed views about higher education and careers in agriculture. This was based on their limited knowledge and stereotypes about agricultural majors and career options. The students highlighted several key reasons why they chose to enroll in agricultural science courses. This included the benefits of dual science credits and the ability to earn an associate degree upon successful completion of their program. Students also loved science and appreciated the science intensive nature of the agricultural courses. Additionally, they thought that the agricultural science courses were better than the other optional courses. The results also showed that electronic media such as radio and TV had a negative impact on students' perceptions about higher education and careers in agriculturally-related fields. Conclusions and recommendations are presented.

  8. The cult of the amateur in agriculture threatens food security.

    PubMed

    Trewavas, Anthony

    2008-09-01

    The incorporation of science and technology into agriculture has led to enormous growth in crop yields, providing food security in many countries. From the 1950s onwards there has been increasing interference in agricultural policy by a few scientists who are marginal to agriculture and from a variety of unqualified groups. These groups and individuals have used fear and anxiety and have greatly exaggerated minor problems to persuade an unqualified public of supposed dangers in food and to try and change agricultural policy. Fear and emotion do not lead to good policy, and the cult of the amateur that has developed could have serious repercussions on vital food security and future agriculture in developing countries; it must be soundly rejected.

  9. Building Interdisciplinary Research and Communication Skills in the Agricultural and Climate Sciences

    Preparing scientists and educators to create and promote practical science-based agricultural approaches to climate change adaptation and mitigation is a main focus of the Regional Approaches to Climate Change (REACCH) project. Social, political and environmental complexities and interactions require that future scientists work across disciplines rather than having isolated knowledge of one specific subject area. Additionally, it is important for graduate students earning M.S. or Ph.D. degrees in agriculture and climate sciences to be able to communicate scientific findings effectively to non-scientific audiences. Unfortunately, university graduate curricula rarely adequately prepare students with these important skills. REACCH recognizes the need for graduate students to have thorough exposure to other disciplines and to be able to communicate information for outreach and education purposes. These priorities have been incorporated into graduate training within the REACCH project. The interdisciplinary nature of the project and its sophisticated digital infrastructure provide graduate students multiple opportunities to gain these experiences. The project includes over 30 graduate students from 20 different disciplines and research foci including agronomy, biogeochemistry, soil quality, conservation tillage, hydrology, pest and beneficial organisms, economics, modeling, remote sensing, science education and climate science. Professional develop workshops were developed and held during annual project meetings to enhance student training. The "Toolbox" survey (http://www.cals.uidaho.edu/toolbox/) was used to achieve effective interdisciplinary communication. Interdisciplinary extension and education projects were required to allow students to gain experience with collaboration and working with stakeholder groups. Results of student surveys and rubrics developed to gauge success in interdisciplinary research and communication may provide a helpful starting point for

  12. Paths of convergence for agriculture, health, and wealth

    PubMed Central

    Dubé, Laurette; Pingali, Prabhu; Webb, Patrick

    2012-01-01

    This special feature calls for forward thinking around paths of convergence for agriculture, health, and wealth. Such convergence aims for a richer integration of smallholder farmers into national and global agricultural and food systems, health systems, value chains, and markets. The articles identify analytical innovation, where disciplines intersect, and cross-sectoral action where single, linear, and siloed approaches have traditionally dominated. The issues addressed are framed by three main themes: (i) lessons related to agricultural and food market growth since the 1960s; (ii) experiences related to the integration of smallholder agriculture into national and global business agendas; and (iii) insights into convergence-building institutional design and policy, including a review of complexity science methods that can inform such processes. In this introductory article, we first discuss the perspectives generated for more impactful policy and action when these three themes converge. We then push thematic boundaries to elaborate a roadmap for a broader, solution-oriented, and transdisciplinary approach to science, policies, and actions. As the global urban population crosses the 50% mark, both smallholder and nonsmallholder agriculture are keys in forging rural–urban links, where both farm and nonfarm activities contribute to sustainable nutrition security. The roadmaps would harness the power of business to reduce hunger and poverty for millions of families, contribute to a better alignment between human biology and modern lifestyles, and stem the spread of noncommunicable chronic diseases.

  9. Economic Drought Impact on Agriculture: analysis of all agricultural sectors affected

    NASA Astrophysics Data System (ADS)

    Gil, M.; Garrido, A.; Hernández-Mora, N.

    2012-04-01

    The analysis of drought impacts is essential to define efficient and sustainable management and mitigation. In this paper we present a detailed analysis of the impacts of the 2004-2008 drought in the agricultural sector in the Ebro river basin (Spain). An econometric model is applied in order to determine the magnitude of the economic loss attributable to water scarcity. Both the direct impacts of drought on agricultural productivity and the indirect impacts of drought on agricultural employment and agroindustry in the Ebro basin are evaluated. The econometric model measures losses in the economic value of irrigated and rainfed agricultural production, of agricultural employment and of Gross Value Added both from the agricultural sector and the agro-industrial sector. The explanatory variables include an index of water availability (reservoir storage levels for irrigated agriculture and accumulated rainfall for rainfed agriculture), a price index representative of the mix of crops grown in each region, and a time variable. The model allows for differentiating the impacts due to water scarcity from other sources of economic losses. Results show how the impacts diminish as we approach the macro-economic indicators from those directly dependent on water abstractions and precipitation. Sectors directly dependent on water are the most affected with identifiable economic losses resulting from the lack of water. From the management perspective implications of these findings are key to develop mitigation measures to reduce drought risk exposure. These results suggest that more open agricultural markets, and wider and more flexible procurement strategies of the agro-industry reduces the socio-economic exposure to drought cycles. This paper presents the results of research conducted under PREEMPT project (Policy relevant assessment of the socioeconomic effects of droughts and floods, ECHO - grant agreement # 070401/2010/579119/SUB/C4), which constitutes an effort to provide

    2014-01-01

    Responding to demands for transformed farming practices requires new forms of knowledge. Given their scale and complexity, agricultural problems can no longer be solved by linear transfers in which technology developed by specialists passes to farmers by way of extension intermediaries. Recent research on alternative approaches has focused on the innovation systems formed by interactions between heterogeneous actors. Rather than linear transfer, systems theory highlights network facilitation as a specialized function. This paper contributes to our understanding of such facilitation by investigating the networks in which farmers discuss science. We report findings based on the study of a pastoral farming experiment collaboratively undertaken by a group of 17 farmers and five scientists. Analysis of prior contact and alter sharing between the group's members indicates strongly tied and decentralized networks. Farmer knowledge exchanges about the experiment have been investigated using a mix of quantitative and qualitative methods. Network surveys identified who the farmers contacted for knowledge before the study began and who they had talked to about the experiment by 18 months later. Open-ended interviews collected farmer statements about their most valuable contacts and these statements have been thematically analysed. The network analysis shows that farmers talked about the experiment with 192 people, most of whom were fellow farmers. Farmers with densely tied and occupationally homogeneous contacts grew their networks more than did farmers with contacts that are loosely tied and diverse. Thematic analysis reveals three general principles: farmers value knowledge delivered by persons rather than roles, privilege farming experience, and develop knowledge with empiricist rather than rationalist techniques. Taken together, these findings suggest that farmers deliberate about science in intensive and durable networks that have significant implications for theorizing

  14. Sustainable Uses of FGD Gypsum in Agricultural Systems: Introduction.

    PubMed

    Watts, Dexter B; Dick, Warren A

    2014-01-01

    Interest in using gypsum as a management tool to improve crop yields and soil and water quality has recently increased. Abundant supply and availability of flue gas desulfurization (FGD) gypsum, a by-product of scrubbing sulfur from combustion gases at coal-fired power plants, in major agricultural producing regions within the last two decades has attributed to this interest. Currently, published data on the long-term sustainability of FGD gypsum use in agricultural systems is limited. This has led to organization of the American Society of Agronomy's Community "By-product Gypsum Uses in Agriculture" and a special collection of nine technical research articles on various issues related to FGD gypsum uses in agricultural systems. A brief review of FGD gypsum, rationale for the special collection, overviews of articles, knowledge gaps, and future research directions are presented in this introductory paper. The nine articles are focused in three general areas: (i) mercury and other trace element impacts, (ii) water quality impacts, and (iii) agronomic responses and soil physical changes. While this is not an exhaustive review of the topic, results indicate that FGD gypsum use in sustainable agricultural production systems is promising. The environmental impacts of FGD gypsum are mostly positive, with only a few negative results observed, even when applied at rates representing cumulative 80-year applications. Thus, FGD gypsum, if properly managed, seems to represent an important potential input into agricultural systems.

  11. Bioethics Symposium: The ethical food movement: What does it mean for the role of science and scientists in current debates about animal agriculture?

    PubMed

    Croney, C C; Apley, M; Capper, J L; Mench, J A; Priest, S

    2012-05-01

    Contemporary animal agriculture is increasingly criticized on ethical grounds. Consequently, current policy and legislative discussions have become highly controversial as decision makers attempt to reconcile concerns about the impacts of animal production on animal welfare, the environment, and on the efficacy of antibiotics required to ensure human health with demands for abundant, affordable, safe food. Clearly, the broad implications for US animal agriculture of what appears to be a burgeoning movement relative to ethical food production must be understood by animal agriculture stakeholders. The potential effects of such developments on animal agricultural practices, corporate marketing strategies, and public perceptions of the ethics of animal production must also be clarified. To that end, it is essential to acknowledge that people's beliefs about which food production practices are appropriate are tied to diverse, latent value systems. Thus, relying solely on scientific information as a means to resolve current debates about animal agriculture is unlikely to be effective. The problem is compounded when scientific information is used inappropriately or strategically to advance a political agenda. Examples of the interface between science and ethics in regards to addressing currently contentious aspects of food animal production (animal welfare, antimicrobial use, and impacts of animal production practices on the environment) are reviewed. The roles of scientists and science in public debates about animal agricultural practices are also examined. It is suggested that scientists have a duty to contribute to the development of sound policy by providing clear and objectively presented information, by clarifying misinterpretations of science, and by recognizing the differences between presenting data vs. promoting their own value judgments in regard to how and which data should be used to establish policy. Finally, the role of the media in shaping public opinions

    Wilson, Alphus D.

    2013-01-01

    Electronic-nose (e-nose) instruments, derived from numerous types of aroma-sensor technologies, have been developed for a diversity of applications in the broad fields of agriculture and forestry. Recent advances in e-nose technologies within the plant sciences, including improvements in gas-sensor designs, innovations in data analysis and pattern-recognition algorithms, and progress in material science and systems integration methods, have led to significant benefits to both industries. Electronic noses have been used in a variety of commercial agricultural-related industries, including the agricultural sectors of agronomy, biochemical processing, botany, cell culture, plant cultivar selections, environmental monitoring, horticulture, pesticide detection, plant physiology and pathology. Applications in forestry include uses in chemotaxonomy, log tracking, wood and paper processing, forest management, forest health protection, and waste management. These aroma-detection applications have improved plant-based product attributes, quality, uniformity, and consistency in ways that have increased the efficiency and effectiveness of production and manufacturing processes. This paper provides a comprehensive review and summary of a broad range of electronic-nose technologies and applications, developed specifically for the agriculture and forestry industries over the past thirty years, which have offered solutions that have greatly improved worldwide agricultural and agroforestry production systems.

  15. Plant biotechnology patents: applications in agriculture and medicine.

    PubMed

    Hefferon, Kathleen

    2010-06-01

    Recent advances in agricultural biotechnology have enabled the field of plant biology to move forward in great leaps and bounds. In particular, recent breakthroughs in molecular biology, plant genomics and crop science have brought about a paradigm shift of thought regarding the manner by which plants can be utilized both in agriculture and in medicine. Besides the more well known improvements in agronomic traits of crops such as disease resistance and drought tolerance, plants can now be associated with topics as diverse as biofuel production, phytoremediation, the improvement of nutritional qualities in edible plants, the identification of compounds for medicinal purposes in plants and the use of plants as therapeutic protein production platforms. This diversification of plant science has been accompanied by the great abundance of new patents issued in these fields and, as many of these inventions approach commercial realization, the subsequent increase in agriculturally-based industries. While this review chapter is written primarily for plant scientists who have great interest in the new directions being taken with respect to applications in agricultural biotechnology, those in other disciplines, such as medical researchers, environmental scientists and engineers, may find significant value in reading this article as well. The review attempts to provide an overview of the most recent patents issued for plant biotechnology with respect to both agriculture and medicine. The chapter concludes with the proposal that the combined driving forces of climate change, as well as the ever increasing needs for clean energy and food security will play a pivotal role in leading the direction for applied plant biotechnology research in the future.

    More than 4 years has passed since the accident at the Fukushima Nuclear Power Plant. Immediately after the accident, 40 to 50 academic staff of the Graduate School of Agricultural and Life Sciences at the University of Tokyo created an independent team to monitor the behavior of the radioactive materials in the field and their effects on agricultural farm lands, forests, rivers, animals, etc. When the radioactive nuclides from the nuclear power plant fell, they were instantly adsorbed at the site where they first touched; consequently, the fallout was found as scattered spots on the surface of anything that was exposed to the air at the time of the accident. The adsorption has become stronger over time, so the radioactive nuclides are now difficult to remove. The findings of our study regarding the wide range of effects on agricultural fields are summarized in this report. PMID:27538845

    Bobeck, E A; Combs, D K; Cook, M E

    2014-02-01

    The demographics of incoming university animal science majors have shifted from students with a farm background to urban students with no history of direct livestock contact. Research completed before the Internet was a central source of information indicated that incoming urban students tend to express no opinion or a neutral opinion regarding livestock agriculture issues. Due to the changing background of incoming students enrolled in introductory university-level animal science classes, we sought to determine 1) if livestock background (self-identified as raised in a farm or urban setting), sex, or animal science career interest influenced the opinions of incoming students regarding critical issues involving livestock farming practices and 2) if 15 wk of introductory animal science instruction changed student opinions. A total of 224 students were given 2 identical anonymous surveys (start and end of 15 wk) with 5 demographic questions and 9 animal issue statements. For each statement, students marked their opinion by placing a vertical line on a continuous 130 mm horizontal line, where a vertical line placed at 0 mm = strongly agree and 130 mm = strongly disagree. Data were analyzed by ANOVA to determine any significant effects of instruction, background, sex, and future career preference on survey responses. Before instruction, urban students were less agreeable than farm students that animal farming was moral and humane and that farmers are concerned about animal welfare and livestock are of value to society (P ≤ 0.05). Urban students were more likely than farm students to purchase organic foods or food based on environmental/welfare standards (P ≤ 0.05). Introductory animal science instruction resulted in students becoming more agreeable that animal farming was humane, farmers are concerned about animal welfare, and animal agriculture is a value to society (P ≤ 0.05). Postinstruction, students were more likely to buy food products based on price (P

    Global support for Conservation Agriculture (CA) as a pathway to Sustainable Intensification is strong. CA revolves around three principles: no-till (or minimal soil disturbance), soil cover, and crop rotation. The benefits arising from the ease of crop management, energy/cost/time savings, and soil and water conservation led to widespread adoption of CA, particularly on large farms in the Americas and Australia, where farmers harness the tools of modern science: highly-sophisticated machines, potent agrochemicals, and biotechnology. Over the past 10 years CA has been promoted among smallholder farmers in the (sub-) tropics, often with disappointing results. Growing evidence challenges the claims that CA increases crop yields and builds-up soil carbon although increased stability of crop yields in dry climates is evident. Our analyses suggest pragmatic adoption on larger mechanized farms, and limited uptake of CA by smallholder farmers in developing countries. We propose a rigorous, context-sensitive approach based on Systems Agronomy to analyze and explore sustainable intensification options, including the potential of CA. There is an urgent need to move beyond dogma and prescriptive approaches to provide soil and crop management options for farmers to enable the Sustainable Intensification of agriculture.

Combined with the connotation of fusion agriculture and tourism, respectively from the time and space utilization efficiency, cash cost, elements of input and output form, etc, gives high-efficiency agriculture a new connotation. Under the perspective of a combined agriculture with tourism, efficient use of time and space, low realized cost, less costs and output form of agriculture, this is highly effective agriculture.

    The public sector is an important source of agricultural research as the agricultural sector in many countries consists of a number of individual farmers who have difficulty in bearing the cost of research and development. Public institutes for testing and research called Kosetsushi help agriculture and manufacturing improve labor productivity through technology transfer activities, whereby constituting an important component of regional innovation systems in Japan. This study establishes panel data of agricultural Kosetsushi and examines whether their research activities are responsive to local needs and which type of research effort is conducive to the promotion of agricultural product innovations. Estimation results reveal variations across plants in the impacts of agricultural clusters on research on the plant conducted by Kosetsushi located in the cluster. A positive impact is observed only for vegetable while negative or statistically insignificant relationships are found for rice, fruit, and flower. The impact of research on plant breeding on agricultural product innovations also varies across plants. Policy implications of the major findings are discussed.

    Despite the high and relatively stable overall growth of the economy, India's agriculture sector is underperforming and a vast section of the population remains undernourished. To explore the possible interplay between agricultural performance and malnutrition indicators to see whether states that perform better in agriculture record better nutritional outcomes. Correlation analysis and a simple linear regression model were used to study the relationship between agricultural performance and malnutrition among children under 5 years of age and adults from 15 to 49 years of age at 20 major states using data from the National Family Health Survey-3 for the year 2005/06 and the national accounts. Indicators of the level of agricultural performance or income have a strong and significant negative relationship with indices of undernutrition among adults and children, a result suggesting that improvement of agricultural productivity can be a powerful tool to reduce undernutrition across the vast majority of the population. In addition to agriculture, access to sanitation facilities and women's literacy were also found to be strong factors affecting malnutrition. Access to healthcare for women and child-care practices, in particular breastfeeding within 1 hour after birth, are other important determinants of malnutrition among adults and children. Malnutrition is a multidimensional problem that requires multisectoral interventions. The findings show that improving agricultural performance can have a positive impact on nutritional outcomes. However, improvements in agriculture alone cannot be effective in combating malnutrition if several other mediating factors are not in place. Interventions to improve education, health, sanitation and household infrastructure, and care and feeding practices are critical. Innovative strategies that integrate agriculture and nutrition programs stand a better chance of combating the malnutrition problem.

  4. The use of GMOs (genetically modified organisms): agricultural biotechnology or agricultural biopolitics?

    PubMed

    Nuti, Marco; Felici, Cristiana; Agnolucci, Monica

    2007-01-01

    Agricultural biotechnologies embrace a large array of conventional and modern technologies, spanning from composting organic by-products of agriculture to innovative improvement of quality traits of about twenty out of the mostly cultivated plants. In EU a rather restrictive legislative framework has been installed for GMOs, requiring a risk assessment disproportionate with respect to conventional agriculture and organic farming products. The latter are far from being proved safe for human and animal health, and for the environment. Biotechnology of GMOs has been overtaken by biopolitics. On one side there are biotechnological challenges to be tackled, on another side there is plenty of ground for biopolitical decisions about GMOs. Perhaps the era of harsh confrontation could be fruitfully replaced by sensible cooperation, in order to get a sustainable agricultural development.

    This study discusses major issues concerning fuels derived from agricultural products. Agricultural products, particularly sugarcane and corn, are currently meeting major energy needs in Florida. Recent figures indicate that about 10% of the gasoline sold in Florida is ethanol enriched. This gasohol contains a 10% mix of ethanol, which is generally produced from corn or sugarcane molasses. Sugarcane residues (bagasse) also supply most of the fuel to power Florida's large sugar processing industry. These products have the potential to play an expanded role in Florida's energy future. Principle areas of interest are: Growing crops such as napier grass or harvestingmore » water hyacinths to produce methane that can be substituted for natural gas; expanded use of sugar, starch, and industrial and agricultural wastes as raw materials for ethanol production; improved efficiency in conversion processes such as anaerobic digestion and fermentation. The Institute of Food and Agricultural Sciences at the University of Florida plays a leading national role in energy crops research, while Walt Disney World is using a demonstration project to convert water hyacinths into methane. Increased use of fuels produced from agricultural products depends largely on their costs compared to other fuels. Ethanol is currently attractive because of federal and state tax incentives. The growth potential of ethanol and methane is enhanced by the ease with which they can be blended with fossil fuels and thereby utilize the current energy distribution system. Neither ethanol nor methane appear able to compete in the free market for mass distribution at present, although studies indicate that genetic engineering and more efficient conversion processes may lower prices to cost effective levels. These fuels will be most cost effective in cases where waste products are utilized and the fuel is used close to the site of production.« less

    Arbuscular mycorrhizal (AM) fungi are rich in diversity in agricultural ecosystem, playing a vital role based on their unique community structure. Host plants and environmental factors have important effects on AM fungal community structure, so do the agricultural practices which deserve to pay attention to. This paper summarized the research advances in the effects of agricultural practices such as irrigation, fertilization, crop rotation, intercropping, tillage, and pesticide application on AM fungal community structure, analyzed the related possible mechanisms, discussed the possible ways in improving AM fungal community structure in agricultural ecosystem, and put forward a set of countermeasures, i.e., improving fertilization system and related integrated techniques, increasing plant diversity in agricultural ecosystem, and inoculating AM fungi, to enhance the AM fungal diversity in agricultural ecosystem. The existing problems in current agricultural practices and further research directions were also proposed.

    Although many mosquito species develop within agricultural landscapes where they are potentially exposed to agricultural chemicals (fertilizers and pesticides), the effects of these chemicals on mosquito biology remain poorly understood. This study investigated the effects of sublethal concentrations of four agricultural chemicals on the life history traits of Anopheles arabiensis and Culex quinquefasciatus mosquitoes. Field and laboratory experiments were conducted to examine how sublethal concentrations of four agricultural chemicals: an insecticide (cypermethrin), a herbicide (glyphosate), and two nitrogenous fertilizers (ammonium sulfate and diammonium phosphate) alter oviposition site selection, emergence rates, development time, adult body size, and longevity of An. arabiensis and Cx. quinquefasciatus. Both mosquito species had preference to oviposit in fertilizer treatments relative to pesticide treatments. Emergence rates for An. arabiensis were significantly higher in the control and ammonium sulfate treatments compared to cypermethrin treatment, while emergence rates for Cx. quinquefasciatus were significantly higher in the diammonium phosphate treatment compared to glyphosate and cypermethrin treatments. For both mosquito species, individuals from the ammonium sulfate and diammonium phosphate treatments took significantly longer time to develop compared to those from cypermethrin and glyphosate treatments. Although not always significant, males and females of both mosquito species tended to be smaller in the ammonium sulfate and diammonium phosphate treatments compared to cypermethrin and glyphosate treatments. There was no significant effect of the agrochemical treatments on the longevity of either mosquito species. These results demonstrate that the widespread use of agricultural chemicals to enhance crop production can have unexpected effects on the spatial distribution and abundance of mosquito vectors of malaria and lymphatic filariasis.

  13. Cultural Patterns of Soil Understanding in Organic Agriculture

    2017-04-01

    Different branches of modern agriculture rely on different cultural patterns of soil understanding; and they are supported by different schools of thought in soil science with their specific values and perspectives. For example, the European branch of organic agriculture, as it developed mainly in the 20th Century, is rooted in specific cultural concepts and was supported by associated minorities, or rather marginalised tendencies, within the soil science community. Some cases: It is about the transformations of living or organic matter, linked with debates on "microbes" and "life particles", "tissues" and macromolecules in the humus-sphere. It is about the "industrialised economical-technical paradigm" versus an "organic" or "ecological paradigm" - whatever both may be. It is about the relevance respectively of the "duties" of control by power, or by relatedness and "intercourse" in agricultural human-nature interaction. It is about the male and female qualities of effective God-images - both in their "religious" as well as their "secular" representations in individuals' and society's relation with nature and when dealing with soil. In today's conceptual and strategic debates and power struggles over how to sustainably feed from the land, we see patterns similar to those from the 19th and 20th Centuries in action. But the threats they pose are not yet sufficiently realised; the opportunities they offer are not yet sufficiently fulfilled. In this presentation, using the example of cultural patterns inside organic agriculture in Europe, some cultural problems and tasks will be highlighted, to which geosciences are of course confronted, being part of human society.

    Water and land resources play vital roles in agricultural growth. They not only remarkably support overall economic growth, but may also restrict agricultural development. To document the influence of water and land on agriculture, we examined the "drag effects" of these two resources in limiting agricultural production. In this study, data from eight counties collected during 2000-2012 from the Heihe Agricultural Production Area in Gansu Province were used to analyze the drag effects of water and land resources on agricultural growth. These effects varied largely among the eight counties, which was consistent with the availability of these resources. This study will give scientific support to coordinating development with the availability of water and land resources in agricultural areas of China

    The interesting characteristics of electrospun nanofibres, such as high surface-to-volume ratio, nanoporosity, and high safety, make them suitable candidates for use in a variety of applications. In the recent decade, electrospun nanofibres have been applied to different potential fields such as filtration, wound dressing, drug delivery, etc. and a significant number of review papers have been published in these fields. However, the use of electrospun nanofibres in agriculture is comparatively novel and is still in its infancy. In this paper, the specific applications of electrospun nanofibres in agriculture and food science, including plant protection using pheromone-loaded nanofibres, plant protection using encapsulation of biocontrol agents, preparation of protective clothes for farm workers, encapsulation of agrochemical materials, deoxyribonucleic acid extraction in agricultural research studies, pre-concentration and measurement of pesticides in crops and environmental samples, preparation of nanobiosensors for pesticide detection, encapsulation of food materials, fabrication of food packaging materials, and filtration of beverage products are reviewed and discussed. This paper may help researchers develop the use of electrospun nanofibres in agriculture and food science to address some serious problems such as the intensive use of pesticides. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    2015-12-01

    Innovative training in 'Sustainable Agriculture' for an increasingly STEM-dependent agricultural sector will require a combination of approaches and technologies for global agricultural production to increase while offsetting climate change. Climate change impacts the water resources of nations as normal global weather patterns are altered during El Nino events. Agricultural curricula must incorporate awareness of 'climate change' in order to find novel ways to (1) assure global food security; (2) improve soil productivity and conservation; (3) improve crop yields and irrigation; (4) inexpensively develop site specific principles of crop management based on variable soil and associated hydrological properties; and (5) improve precision farming. In February 2015, Central State University (CSU), Ohio became an 1890 Land-Grant institution vital to the sustainability of Ohio's agricultural sector. Besides agricultural extension, the agriculture curriculum at CSU integrates multidisciplinary courses in science, technology engineering, agriculture, and mathematics (STEAM). The agriculture program could benefit from a technology-driven, interdisciplinary soil science course that promotes climate change education and climate literacy while being offered in both a blended and collaborative learning environment. The course will focus on the dynamics of microscale to mesoscale processes occurring in farming systems, those of which impact climate change or could be impacted by climate change. Elements of this course will include: climate change webinars; soil-climate interactions; carbon cycling; the balance of carbon fluxes between soil storage and atmosphere; microorganisms and soil carbon storage; paleoclimate and soil forming processes; geophysical techniques used in the characterization of soil horizons; impact of climate change on soil fertility; experiments; and demonstrations.

    In the real world market, agricultural commodity are imposed with fluctuating prices. This means that the price of agricultural products are relatively volatile, which means that agricultural business is a quite risky business for farmers. This paper presents some mathematical models to model such risks in the form of its volatility, based on certain assumptions. The proposed models are time varying volatility model, as well as time varying volatility with mean reversion and with seasonal mean equation models. Implementation on empirical data show that agricultural products are indeed risky.

    2000-06-01

    Any thorough examination of the present and future of agricultural education must certainly begin with a look into its past. Since the creation of the United States, many leading American philosophers have viewed a strong agrarian culture as the bedrock of American vigor. These same philosophers repeatedly noted the significance of comprehensive agricultural education to a nation rich in agricultural wealth. The signing of the Agricultural Colleges Act legitimized the concept of formal education in the agricultural sciences and provided funding for such education. The Act, which came to be known as the Morrill Act, after one of its primary authors, stressed the importance of comprehensive education. In fact, the inclusion of liberal studies was specifically mentioned in the Morrill Act and was defended repeatedly by Morrill himself. Comprehensive education prevented graduating technically trained students who were lacking in the basic outcomes of education--critical, comprehensive problem solving, cohesive thought, and effective communication. However, throughout history, the demands of a growing population coupled with rapid advancements in scientific knowledge led to a gradual move away from comprehensive education in agricultural sciences toward increasing specialization, resulting in more narrowly trained students. Today's agricultural students are technically well versed but often lack the skill and knowledge required for cohesive thought and critical problem solving. Addressing the multitude of challenges facing leaders in the future of agriculture requires much more than technical skill. These challenges require quick, yet careful thinkers and communicators who can respond to changing market structure and consumer demand in a dynamic way. Students who are a product of a conscious move toward amalgamation of burgeoning scientific knowledge and technical prowess with an integrative education emphasizing relationships between disciplines would better serve

    2010-01-01

    A doctoral program in Systems Agriculture was initiated at West Texas A&M University, Canyon, TX, in September, 2003. The stated objective of the program was "..to prepare leaders for the agricultural industry that are trained in a multidisciplinary, research-based curriculum that emphasizes a systems approach to problem solving". The program offers a single doctoral degree in Agriculture and accepts qualified students with a master's or professional degree in agricultural or related disciplines. Courses related to systems methodologies, leadership, agricultural economics, plant and soil science, and animal science are required. Additional program requirements include a systems research project and dissertation, leadership training, and written and oral exams. The program has exceeded enrollment and graduation targets, suggesting interest in this approach to a doctoral degree. Students have entered the program with M.S. backgrounds in education, traditional agricultural disciplines, veterinary medicine, business, and physics. Graduates have gained employment in industry, university teaching and research, government research/administration, and extension. Doctoral student projects in systems agriculture contributed to curriculum changes and to the conceptual framework adopted by a multi-state research group. Designing and teaching courses for students with diverse backgrounds has been challenging. Development of a common understanding of systems agriculture was identified by a third-party program review as an issue for faculty. Development and maintenance of program standards and administrative procedures posed additional challenges. Leadership, administrative support, and timely and continuing program assessment are suggested as necessary components for a nontraditional doctoral program.

  15. Comparative analysis of environmental impacts of agricultural production systems, agricultural input efficiency, and food choice

    2017-06-01

    Global agricultural feeds over 7 billion people, but is also a leading cause of environmental degradation. Understanding how alternative agricultural production systems, agricultural input efficiency, and food choice drive environmental degradation is necessary for reducing agriculture’s environmental impacts. A meta-analysis of life cycle assessments that includes 742 agricultural systems and over 90 unique foods produced primarily in high-input systems shows that, per unit of food, organic systems require more land, cause more eutrophication, use less energy, but emit similar greenhouse gas emissions (GHGs) as conventional systems; that grass-fed beef requires more land and emits similar GHG emissions as grain-feed beef; and that low-input aquaculture and non-trawling fisheries have much lower GHG emissions than trawling fisheries. In addition, our analyses show that increasing agricultural input efficiency (the amount of food produced per input of fertilizer or feed) would have environmental benefits for both crop and livestock systems. Further, for all environmental indicators and nutritional units examined, plant-based foods have the lowest environmental impacts; eggs, dairy, pork, poultry, non-trawling fisheries, and non-recirculating aquaculture have intermediate impacts; and ruminant meat has impacts ∼100 times those of plant-based foods. Our analyses show that dietary shifts towards low-impact foods and increases in agricultural input use efficiency would offer larger environmental benefits than would switches from conventional agricultural systems to alternatives such as organic agriculture or grass-fed beef.

    1998-02-01

    The recently released National Research Council report, Colleges of Agriculture at the Land Grant Universities: Public Service and Public Policy (NRC 1996), may be of particular interest to poultry scientists. The dramatic changes in U.S. agriculture, which were among the factors that spawned the NRC's interest in a study of the land grant colleges, are probably nowhere more evident than in the poultry industry. Furthermore, there is considerable discussion in the report about the value of multi-state and multi-disciplinary efforts in teaching, research, and extension. The need to attract nontraditional students to poultry science curricula and to produce graduates well-suited for modern, vertically integrated agricultural enterprises, such as poultry, are a high priority.

    2014-12-01

    Climate-smart agriculture (CSA) is an approach for transforming and reorienting agricultural systems to support food security under the new realities of climate change. Widespread changes in rainfall and temperature patterns threaten agricultural production and increase the vulnerability of people dependent on agriculture for their livelihoods, which includes most of the world's poor. Climate change disrupts food markets, posing population-wide risks to food supply. Threats can be reduced by increasing the adaptive capacity of farmers as well as increasing resilience and resource use efficiency in agricultural production systems. CSA promotes coordinated actions by farmers, researchers, private sector, civil society and policymakers towards climate-resilient pathways through four main action areas: (1) building evidence; (2) increasing local institutional effectiveness; (3) fostering coherence between climate and agricultural policies; and (4) linking climate and agricultural financing. CSA differs from 'business-as-usual' approaches by emphasizing the capacity to implement flexible, context-specific solutions, supported by innovative policy and financing actions.

    2015-11-01

    During the 40th Annual Meeting of The Toxicology Forum, the current and potential future science, regulations, and politics of agricultural biotechnology were presented and discussed. The meeting session described herein focused on the technology of RNA interference (RNAi) in agriculture. The general process by which RNAi works, currently registered RNAi-based plant traits, example RNAi-based traits in development, potential use of double stranded RNA (dsRNA) as topically applied pesticide active ingredients, research related to the safety of RNAi, biological barriers to ingested dsRNA, recent regulatory RNAi science reviews, and regulatory considerations related to the use of RNAi in agriculture were discussed. Participants generally agreed that the current regulatory framework is robust and appropriate for evaluating the safety of RNAi employed in agricultural biotechnology and were also supportive of the use of RNAi to develop improved crop traits. However, as with any emerging technology, the potential range of future products, potential future regulatory frameworks, and public acceptance of the technology will continue to evolve. As such, continuing dialogue was encouraged to promote education of consumers and science-based regulations. Copyright © 2015 Elsevier Inc. All rights reserved.

    China is a large agricultural country, and the healthy development of agriculture is related to the stability of the whole society. The agricultural production and management of agricultural products are confronted with many risks, especially the market risks. Option contract is the object of option market transaction, so it is very important to study the option contract of agricultural products. Option trading separates the risk and profit, so that the trader can avoid the risk while retaining the opportunity to obtain income. The option has the characteristics of low transaction cost, simple and efficient, so it is suitable for small and medium investors.

    2010-01-01

    The Department of Food Science and Technology- Bogor Agricultural University (DFST-IPB), Indonesia is one of the oldest Departments of its kind in Indonesia. The Department has been founded since 1964 under the Faculty of Agricultural Engineering and Technology. The Department has a core competence in the area of food science and technology, particularly in the development of food chemistry, food microbiology, food process engineering, food analysis, food quality and safety. The Department offers educational programs: Undergraduate Program in Food Technology and Master as well as Doctorate Program in Food Science. The Master and Doctorate Program are enrolled by 35 students annually. Globalisation as a global phenomenon has been influencing DFST doctoral program as internationalization in response to globalization is a common feature in majority universities. Facing this challenge, DFST Doctorate Program's has made some efforts to provide students with international atmosphere, including having international guest lecturers, inviting prospective international students, and initiating join program with international universities. In addition, research focusing in tropical food and collaboration with international universities may need to be improved to widen the network, increase publication and place DFST doctorate program visible in the international forum. This paper is intended to reveal the perceived challenges of globalization for food science doctoral program (DFST-IPB) and to what extent and in what form internationalization has been achieved. However, it should be noted that this article is selective rather than comprehensive in reflecting on the internationalization process of food science doctoral program (DFST-IPB).

  7. Global hunger: a challenge to agricultural, food, and nutritional sciences.

    PubMed

    Wu, Shiuan-Huei; Ho, Chi-Tang; Nah, Sui-Lin; Chau, Chi-Fai

    2014-01-01

    Hunger has been a concern for generations and has continued to plague hundreds of millions of people around the world. Although many efforts have been devoted to reduce hunger, challenges such as growing competitions for natural resources, emerging climate changes and natural disasters, poverty, illiteracy, and diseases are posing threats to food security and intensifying the hunger crisis. Concerted efforts of scientists to improve agricultural and food productivity, technology, nutrition, and education are imperative to facilitate appropriate strategies for defeating hunger and malnutrition. This paper provides some aspects of world hunger issues and summarizes the efforts and measures aimed to alleviate food problems from the food and nutritional sciences perspectives. The prospects and constraints of some implemented strategies for alleviating hunger and achieving sustainable food security are also discussed. This comprehensive information source could provide insights into the development of a complementary framework for dealing with the global hunger issue.

  9. Is rangeland agriculture sustainable?

    PubMed

    Heitschmidt, R K; Vermeire, L T; Grings, E E

    2004-01-01

    The objective of this paper is to examine the sustainability of rangeland agriculture (i.e., managed grazing) on a world-wide basis, with a focus on North America. Sustainability is addressed on three fronts: 1) ecological, 2) economic, and 3) social acceptance. Based on previous and on-going research, we suggest that employment of science-based rangeland grazing management strategies and tactics can ensure ecological sustainability. The formidable challenge in employing such technology centers around the need to balance efficiency of solar energy capture and subsequent harvest efficiencies across an array of highly spatially and temporally variable vegetation growing conditions using animals that graze selectively. Failure to meet this fundamental challenge often accelerates rangeland desertification processes, and in some instances, enhances rate and extent of the invasion of noxious weeds. We also suggest that the fundamental reason that ecologically sound grazing management technologies are often not employed in the management of grazed ecological systems is because social values drive management decisions more so than ecological science issues. This is true in both well-developed societies with substantial economic resources and in less-developed societies with few economic resources. However, the social issues driving management are often entirely different, ranging from multiple-use issues in developed countries to human day-to-day survival issues in poorly developed countries. We conclude that the long-term sustainability of rangeland agriculture in 1) developed societies depends on the ability of rangeland agriculturalists to continually respond in a dynamic, positive, proactive manner to ever-changing social values and 2) less-developed societies on their ability to address the ecological and social consequences arising from unsustainable human populations before the adoption of science-based sustainable rangeland management technologies.

    2008-01-01

    Recent developments in agricultural science and technology have the potential to transform the agricultural sector in the developing world. These technological advances constitute key drivers of economic growth and hold great promise for poverty reduction in sub-Saharan Africa (SSA). Agricultural research and development in Africa is undergoing a major paradigm shift. Until recently, public-sector institutions in Africa worked in isolation to create and disseminate agricultural technologies to smallholder farmers. However, they need access to improved proprietary technologies developed for the most part by the private sector in developed countries. These technologies are currently concentrated in the hands of a few large corporations and are protected by intellectual property rights. The African Agricultural Technology Foundation (AATF) is a new initiative addressing the challenges associated with the access, development, and deployment of agricultural technologies to smallholder farmers in SSA. This article describes the AATF model of facilitating the creation of partnership alliances dedicated to promote and support collaboration among a wide variety of public- and private-sector organizations around shared agricultural research and development goals for the public good. It explains AATF's public-private partnership framework for technology delivery in the light of market failures, institutional constraints, and systemic weaknesses, which impede public-sector organizations from accessing and delivering pro-poor knowledge and technology to farmers. The article provides policy makers, research managers, and business decision makers with an understanding of how access to, and delivery of, proprietary technologies could contribute to food security and the improvement of farmers' livelihoods in Africa.

  18. Perceived agricultural runoff impact on drinking water.

    PubMed

    Crampton, Andrea; Ragusa, Angela T

    2014-09-01

    Agricultural runoff into surface water is a problem in Australia, as it is in arguably all agriculturally active countries. While farm practices and resource management measures are employed to reduce downstream effects, they are often either technically insufficient or practically unsustainable. Therefore, consumers may still be exposed to agrichemicals whenever they turn on the tap. For rural residents surrounded by agriculture, the link between agriculture and water quality is easy to make and thus informed decisions about water consumption are possible. Urban residents, however, are removed from agricultural activity and indeed drinking water sources. Urban and rural residents were interviewed to identify perceptions of agriculture's impact on drinking water. Rural residents thought agriculture could impact their water quality and, in many cases, actively avoided it, often preferring tank to surface water sources. Urban residents generally did not perceive agriculture to pose health risks to their drinking water. Although there are more agricultural contaminants recognised in the latest Australian Drinking Water Guidelines than previously, we argue this is insufficient to enhance consumer protection. Health authorities may better serve the public by improving their proactivity and providing communities and water utilities with the capacity to effectively monitor and address agricultural runoff.

    This study aimed at observing the development of agricultural land use in Bungo Regency, Jambi Province, for other purposes, such as plantation, mining, and other commercial buildings. According to the sustainable agriculture supposed by the government, a change in land use has become an important issue to be taken into account as such that the change does not tend to damage the environment. The research findings from Bungo Regency demonstrated the change in agricultural land into copra and rubber plantation areas. Local people had changed their mindset towards reluctance to become farmers, which caused the loss of farmer regeneration and weakened the farmer exchange rate towards the agricultural commodities.

  4. Pulmonary health effects of agriculture.

    PubMed

    Nordgren, Tara M; Bailey, Kristina L

    2016-03-01

    Occupational exposures in the agricultural industry are associated with numerous lung diseases, including chronic obstructive pulmonary disease, asthma, hypersensitivity pneumonitis, lung cancer, and interstitial lung diseases. Efforts are ongoing to ascertain contributing factors to these negative respiratory outcomes and improve monitoring of environmental factors leading to disease. In this review, recently published studies investigating the deleterious effects of occupational exposures in the agricultural industry are discussed. Occupational exposures to numerous agricultural environment aerosols, including pesticides, fungi, and bacteria are associated with impaired respiratory function and disease. Increases in certain farming practices, including mushroom and greenhouse farming, present new occupational exposure concerns. Improved detection methods may provide opportunities to better monitor safe exposure levels to known lung irritants. In the agricultural industry, occupational exposures to organic and inorganic aerosols lead to increased risk for lung disease among workers. Increased awareness of respiratory risks and improved monitoring of agricultural environments are necessary to limit pulmonary health risks to exposed populations.

    Remote Sensing Laboratory, Field Science Center, Graduate School of Agriculture Science, Tohoku University starts at April 2004. For studies and education at the laboratory we are now developing the system of remote sensing and GIS. Earth Remote Sensing Data Analysis Center (ERSDAC) made the Home Pages of Terra/ASTER Image Web Library 3 "The Major Airport of the World." http://www.Ersdac.or.jp/ASTERimage3/library_E.html. First, we check the Airport Data to use agricultural understanding for the world. Almost major airport is located in rural area and surrounded with agriculture field. To survey the agriculture field adjacent to the major airport has almost the same condition of human activities. The images are same size and display about 18km X 14km. We can easily understand field size and surrounding conditions. We study seven airports as follows, 1. Tokyo Narita Airport (NRT), Japan, 2. Taipei Chiang kai Shek International Airport (TPE), Taiwan, 3. Bangkok International Airport (BKK), Thailand, 4. Riyadh King Khalid International Airport (RUH), Saudi Arabia, 5. Charles de Gaulle Airport (CDG), Paris, France, 6. Vienna International Airport (VIE), Austria, 7. Denver International Airport (DEN), CO, USA. At the area of Tokyo Narita Airport, there are many golf courses, big urban area and small size of agricultural fields. At Taipei Airport area are almost same as Tokyo Narita Airport area and there are many ponds for irrigations. Bangkok Airport area also has golf courses and many ponds for irrigation water. Riyadh Airport area is quite different from others, and there are large bare soils and small agriculture fields with irrigation and circle shape. Paris Airport area and Vienna Airport area are almost agricultural fields and there are vegetated field and bare soil fields because of crop rotation. Denver Airport area consists of almost agriculture fields and each field size is very large. The advantages of ASTER data are as follows, 1. High-resolution and large

    As part of a larger study of mercury (Hg) biogeochemistry and bioaccumulation in agricultural (rice growing) and non-agricultural wetlands in California's Central Valley, USA, seasonal and spatial controls on methylmercury (MeHg) production were examined in surface sediment. Three types of shallowly-flooded agricultural wetlands (white rice, wild rice, and fallow fields) and two types of managed (non-agricultural) wetlands (permanently and seasonally flooded) were sampled monthly-to-seasonally. Dynamic seasonal changes in readily reducible ‘reactive’ mercury (Hg(II)R), Hg(II)-methylation rate constants (kmeth), and concentrations of electron acceptors (sulfate and ferric iron) and donors (acetate), were all observed in response to field management hydrology, whereas seasonal changes in these parameters were more muted in non-agricultural managed wetlands. Agricultural wetlands exhibited higher sediment MeHg concentrations than did non-agricultural wetlands, particularly during the fall through late-winter (post-harvest) period. Both sulfate- and iron-reducing bacteria have been implicated in MeHg production, and both were demonstrably active in all wetlands studied. Stoichiometric calculations suggest that iron-reducing bacteria dominated carbon flow in agricultural wetlands during the growing season. Sulfate-reducing bacteria were not stimulated by the addition of sulfate-based fertilizer to agricultural wetlands during the growing season, suggesting that labile organic matter, rather than sulfate, limited their activity in these wetlands. Along the continuum of sediment geochemical conditions observed, values of kmeth increased approximately 10,000-fold, whereas Hg(II)R decreased 100-fold. This suggests that, with respect to the often opposing trends of Hg(II)-methylating microbial activity and Hg(II) availability for methylation, microbial activity dominated the Hg(II)-methylation process, and that along this biogeochemical continuum, conditions that favored

  14. A process-based agricultural model for the irrigated agriculture sector in Alberta, Canada

    NASA Astrophysics Data System (ADS)

    Ammar, M. E.; Davies, E. G.

    2015-12-01

    Connections between land and water, irrigation, agricultural productivity and profitability, policy alternatives, and climate change and variability are complex, poorly understood, and unpredictable. Policy assessment for agriculture presents a large potential for development of broad-based simulation models that can aid assessment and quantification of policy alternatives over longer temporal scales. The Canadian irrigated agriculture sector is concentrated in Alberta, where it represents two thirds of the irrigated land-base in Canada and is the largest consumer of surface water. Despite interest in irrigation expansion, its potential in Alberta is uncertain given a constrained water supply, significant social and economic development and increasing demands for both land and water, and climate change. This paper therefore introduces a system dynamics model as a decision support tool to provide insights into irrigation expansion in Alberta, and into trade-offs and risks associated with that expansion. It is intended to be used by a wide variety of users including researchers, policy analysts and planners, and irrigation managers. A process-based cropping system approach is at the core of the model and uses a water-driven crop growth mechanism described by AquaCrop. The tool goes beyond a representation of crop phenology and cropping systems by permitting assessment and quantification of the broader, long-term consequences of agricultural policies for Alberta's irrigation sector. It also encourages collaboration and provides a degree of transparency that gives confidence in simulation results. The paper focuses on the agricultural component of the systems model, describing the process involved; soil water and nutrients balance, crop growth, and water, temperature, salinity, and nutrients stresses, and how other disciplines can be integrated to account for the effects of interactions and feedbacks in the whole system. In later stages, other components such as

    Scientific assessments of agricultural air quality, including estimates of emissions and potential sequestration of greenhouse gases, are an important emerging area of environmental science that offers significant challenges to policy and regulatory authorities. Improvements are needed in measurements, modeling, emission controls, and farm operation management. Controlling emissions of gases and particulate matter from agriculture is notoriously difficult as this sector affects the most basic need of humans, i.e., food. Current policies combine an inadequate science covering a very disparate range of activities in a complex industry with social and political overlays. Moreover, agricultural emissions derive from both area and point sources. In the United States, agricultural emissions play an important role in several atmospherically mediated processes of environmental and public health concerns. These atmospheric processes affect local and regional environmental quality, including odor, particulate matter (PM) exposure, eutrophication, acidification, exposure to toxics, climate, and pathogens. Agricultural emissions also contribute to the global problems caused by greenhouse gas emissions. Agricultural emissions are variable in space and time and in how they interact within the various processes and media affected. Most important in the U.S. are ammonia (where agriculture accounts for approximately 90% of total emissions), reduced sulfur (unquantified), PM25 (approximately 16%), PM110 (approximately 18%), methane (approximately 29%), nitrous oxide (approximately 72%), and odor and emissions of pathogens (both unquantified). Agriculture also consumes fossil fuels for fertilizer production and farm operations, thus emitting carbon dioxide (CO2), oxides of nitrogen (NO(x)), sulfur oxides (SO(x)), and particulates. Current research priorities include the quantification of point and nonpoint sources, the biosphere-atmosphere exchange of ammonia, reduced sulfur

    Agriculture is considered one of the most hazardous occupations. Organic dusts and toxic gases constitute some of the most common and potentially disabling occupational and environmental hazards. The changing patterns of agriculture have paradoxically contributed to both improved working conditions and increased exposure to respiratory hazards. Animal confinement operations with increasing animal density, particularly swine confinement, have contributed significantly to increased intensity and duration of exposure to indoor air toxins. Ongoing research has implicated bacterial endotoxins, fungal spores, and the inherent toxicity of grain dusts as causes of upper and lower airway inflammation and as immunologic agents in both grain and animal production. Animal confinement gases, particularly ammonia and hydrogen sulfide, have been implicated as additional sources of respiratory irritants. It has become evident that a significant percentage of agricultural workers have clinical symptoms associated with long-term exposure to organic dusts and animal confinement gases. Respiratory diseases and syndromes, including hypersensitivity pneumonitis, organic dust toxic syndrome, chronic bronchitis, mucous membrane inflammation syndrome, and asthmalike syndrome, result from ongoing acute and chronic exposures. In this review we focus upon the emerging respiratory health issues in a changing agricultural economic and technologic environment. Environmental and occupational hazards and exposures will be emphasized rather than clinical diagnosis and treatment. Methods of prevention, from both engineering controls and personal respiratory perspectives, are also addressed. PMID:10931789

  3. Agricultural Residues and Other Carbon-Based Resources as Feedstocks for Supercapacitor Electrodes

    NASA Astrophysics Data System (ADS)

    Wang, Yong

    Agricultural residues are generally considered as renewable, economical and environmental-friendly sources to produce carbon-based nanomaterials with many advanced applications. Agricultural residues and by-products generated from the agricultural industry, such as distiller's dried grains with solubles (DDGS), are produced every year on a large scale but lack of proper utilization. As a result, seeking high-value applications based on agricultural residues is essential for the promotion of the economy in agricultural producing states like North Dakota, USA. With the fast development of nanotechnology in recent years, carbon-based nanomaterials have attracted intense research interests in the fields of chemistry, materials science and condensed matter physics due to many unique properties (e.g., chemical and thermal stability, electrical conductivity, mechanical strength, etc.). The development of low-cost nanomaterials using agricultural residues as feedstocks can be a promising route for the sustainable development of the agricultural industry. In this dissertation, the preparation of carbon-based materials from agricultural residues is explored. Many advanced applications are investigated, especially in the field of energy storage devices. The development of porous activate carbons were investigated in detail, and their application as electrode materials of supercapacitors was demonstrated. Hydrothermal carbonization of biomass to produce carbonaceous materials was also covered in this dissertation. In addition to traditional raw materials such as cellulose produced from wood industry, novel material sources such as bacterial cellulose were used to prepare nanocomposites that can be used for the electrodes of supercapacitors. This dissertation contributes to the sustainable development of the agricultural industry in North Dakota.

  18. An investigation of the practice of scientific inquiry in secondary science and agriculture courses

    NASA Astrophysics Data System (ADS)

    Grady, Julie R.

    The purpose of this exploratory qualitative study was to investigate the practice of scientific inquiry in two secondary biology classes and one agriculture class from different schools in different communities. The focus was on teachers' interests and intentions for the students' participation in inquiry, the voices contributing to the inquiry, and students' opportunities to confront their conceptions of the nature of science (NOS). The Partnership for Research and Education in Plants (PREP) served as the context by providing students with opportunities to design and conduct original experiments to help elucidate the function(s) of a disabled gene in Arabidopsis thaliana . Transcripts of teacher and student semi-structured interviews, field notes of classroom observations and classroom conversations, and documents (e.g., student work, teacher handouts, school websites, PREP materials) were analyzed for evidence of the practice of scientific inquiry. Teachers were interested in implementing inquiry because of potential student learning about scientific research and because PREP supports course content and is connected to a larger scientific project outside of the school. Teachers' intentions regarding the implementation of inquiry reflected the complexity of their courses and the students' previous experiences. All inquiries were student-directed. The biology students' participation more closely mirrored the practice of scientists, while the agriculture students were more involved with the procedural display of scientific inquiry. All experiences could have been enhanced from additional knowledge-centered activities regarding scientific reasoning. No activities brought explicit attention to NOS. Biology activities tended to implicitly support NOS while the agriculture class activities tended to implicitly contradict NOS. Scientists' interactions contributed to implied support of the NOS. There were missed opportunities for explicit attention to NOS in all classes

    It is evident that changes in climate will adversely impact various sectors including agriculture and natural resources worldwide. Increased temperatures, longer than normal growing seasons, more frequent extreme weather events, decreased winter snowpack, earlier snowmelt, and vulnerability to pest are some of the examples of changes and impacts documented in the literature. According to the IPCC 2007, mainstreaming` climate change issues into decision-making is an important aspect for sustainability. Due to the lack of locally and regionally focused educational programs, it becomes difficult for people to translate the science into meaningful actions. One of the strengths of the Cooperative Extension system is that it is one of the most trusted sources of science-based information that is locally relevant. In order to utilize strong network of Cooperative Extension system, we implemented a project to provide regionally tailored climate change and sustainable agriculture professional development for Cooperative Extension and Natural Resources Conservation Services (NRCS) educators in 12 states in north central US. We conducted these activities: 1) creation and dissemination of a Climate Change and Sustainable Agriculture Resource Handbook and a curriculum and 2) two climate change and sustainable agriculture workshops. In general, this project resulted in improved ability of Cooperative Extension academics to respond to climate change questions with science-based information. Several workshop attendees also integrated information provided to them through resource handbook and curriculum into their existing programming. In the long-term, we hope these programs will result in educators and farmers making informed choices and recommendations that lead to sustainable agriculture in the face of climate change.

  1. Assessing health in agriculture--towards a common research framework for soils, plants, animals, humans and ecosystems.

    PubMed

    Vieweger, Anja; Döring, Thomas F

    2015-02-01

    In agriculture and food systems, health-related research includes a vast diversity of topics. Nutritional, toxicological, pharmacological, epidemiological, behavioural, sociological, economic and political methods are used to study health in the five domains of soils, plants, livestock, humans and ecosystems. An idea developed in the early founding days of organic agriculture stated that the health of all domains is one and indivisible. Here we show that recent research reveals the existence and complex nature of such health links among domains. However, studies of health aspects in agriculture are often separated by disciplinary boundaries. This restrains the understanding of health in agricultural systems. Therefore we explore the opportunities and limitations of bringing perspectives together from the different domains. We review current approaches to define and assess health in agricultural contexts, comparing the state of the art of commonly used approaches and bringing together the presently disconnected debates in soil science, plant science, veterinary science and human medicine. Based on a qualitative literature analysis, we suggest that many health criteria fall into two paradigms: (1) the Growth Paradigm, where terms are primarily oriented towards continued growth; (2) the Boundary Paradigm, where terms focus on maintaining or coming back to a status quo, recognising system boundaries. Scientific health assessments in agricultural and food systems need to be explicit in terms of their position on the continuum between Growth Paradigm and Boundary Paradigm. Finally, we identify areas and concepts for a future direction of health assessment and research in agricultural and food systems. © 2014 Society of Chemical Industry.

    The supposition that agricultural intensification results in land sparing for conservation has become central to policy formulations across the tropics. However, underlying assumptions remain uncertain and have been little explored in the context of conservation incentive schemes such as policies for Reducing Emissions from Deforestation and forest Degradation, conservation, sustainable management, and enhancement of carbon stocks (REDD+). Incipient REDD+ forest carbon policies in a number of countries propose agricultural intensification measures to replace extensive "slash-and-burn" farming systems. These may result in conservation in some contexts, but will also increase future agricultural land rents as productivity increases, creating new incentives for agricultural expansion and deforestation. While robust governance can help to ensure land sparing, we propose that conservation incentives will also have to increase over time, tracking future agricultural land rents, which might lead to runaway conservation costs. We present a conceptual framework that depicts these relationships, supported by an illustrative model of the intensification of key crops in the Democratic Republic of Congo, a leading REDD+ country. A von Thünen land rent model is combined with geographic information systems mapping to demonstrate how agricultural intensification could influence future conservation costs. Once postintensification agricultural land rents are considered, the cost of reducing forest sector emissions could significantly exceed current and projected carbon credit prices. Our analysis highlights the importance of considering escalating conservation costs from agricultural intensification when designing conservation initiatives.

The Goddard Space Flight Center Earth Sciences Data and Information Services Center Distributed Active Archive Center (GES DISC DAAC) is developing an Agricultural Information System (AIS), evolved from an existing TRMM Online Visualization and Analysis System (TOVAS), which will operationally provide satellite remote sensing data products (e.g., rainfall) and services. The data products will include crop condition and yield prediction maps, generated from a crop growth model with satellite data inputs, in collaboration with the USDA Agricultural Research Service. The AIS will enable the remote, interoperable access to distributed data, by using the GrADS-DODS Server (GDS) and by being compliant with Open GIS Consortium standards. Users will be able to download individual files, perform interactive online analysis, as well as receive operational data flows. AIS outputs will be integrated into existing operational decision support systems for global crop monitoring, such as those of the USDA Foreign Agricultural Service and the U.N. World Food Program.

    Despite much research and investment into understanding and managing nutrients across agricultural landscapes, nutrient runoff to freshwater ecosystems is still a major concern. We argue there is currently a disconnect between the management of watershed surfaces (agricultural landscape) and river networks (riverine landscape). These landscapes are commonly managed separately, but there is limited cohesiveness between agricultural landscape-focused research and river science, despite similar end goals. Interdisciplinary research into stream networks that drain agricultural landscapes is expanding but is fraught with problems. Conceptual frameworks are useful tools to order phenomena, reveal patterns and processes, and in interdisciplinary river science, enable the joining of multiple areas of understanding into a single conceptual–empirical structure. We present a framework for the interdisciplinary study and management of agricultural and riverine landscapes. The framework includes components of an ecosystems approach to the study of catchment–stream networks, resilience thinking, and strategic adaptive management. Application of the framework is illustrated through a study of the Fox Basin in Wisconsin, USA. To fully realize the goal of nutrient reduction in the basin, we suggest that greater emphasis is needed on where best management practices (BMPs) are used within the spatial context of the combined watershed–stream network system, including BMPs within the river channel. Targeted placement of BMPs throughout the riverine landscape would increase the overall buffering capacity of the system to nutrient runoff and thus its resilience to current and future disturbances.

    The main agricultural areas in South Florida are located within the fertile land surrounding Lake Okeechobee. The Atlantic Watershed monthly rainfall anomalies showed a weak but statistically significant correlation to the Oceanic Nino Index (ONI). No other watershed s anomalies showed significant correlations with ONI or the Southern Oscillation Index (SOI). During La Nina months, less sea breeze days and more disturbed days were found to occur compared to El Nino and neutral months. The increase in disturbed days can likely by attributed to the synoptic pattern during La Nina, which is known to be favorable for tropical systems to follow paths that affect South Florida. Overall, neither sea breeze rainfall patterns nor total rainfall patterns in South Florida s main agricultural areas were found to be strongly influenced by the El Nino Southern Oscillation during our study time.

  11. Integrating NASA Satellite Data Into USDA World Agricultural Outlook Board Decision Making Environment To Improve Agricultural Estimates

    2012-01-01

    The USDA World Agricultural Outlook Board (WAOB) is responsible for monitoring weather and climate impacts on domestic and foreign crop development. One of WAOB's primary goals is to determine the net cumulative effect of weather and climate anomalies on final crop yields. To this end, a broad array of information is consulted. The resulting agricultural weather assessments are published in the Weekly Weather and Crop Bulletin, to keep farmers, policy makers, and commercial agricultural interests informed of weather and climate impacts on agriculture. The goal of the current project is to improve WAOB estimates by integrating NASA satellite precipitation and soil moisture observations into WAOB's decision making environment. Precipitation (Level 3 gridded) is from the TRMM Multi-satellite Precipitation Analysis (TMPA). Soil moisture (Level 2 swath and Level 3 gridded) is generated by the Land Parameter Retrieval Model (LPRM) and operationally produced by the NASA Goddard Earth Sciences Data and Information Services Center (GBS DISC). A root zone soil moisture (RZSM) product is also generated, via assimilation of the Level 3 LPRM data by a land surface model (part of a related project). Data services to be available for these products include GeoTIFF, GDS (GrADS Data Server), WMS (Web Map Service), WCS (Web Coverage Service), and NASA Giovanni. Project benchmarking is based on retrospective analyses of WAOB analog year comparisons. The latter are between a given year and historical years with similar weather patterns and estimated crop yields. An analog index (AI) was developed to introduce a more rigorous, statistical approach for identifying analog years. Results thus far show that crop yield estimates derived from TMPA precipitation data are closer to measured yields than are estimates derived from surface-based precipitation measurements. Work is continuing to include LPRM surface soil moisture data and model-assimilated RZSM.

  12. Merging remote sensing data and national agricultural statistics to model change in irrigated agriculture

    Over 22 million hectares (ha) of U.S. croplands are irrigated. Irrigation is an intensified agricultural land use that increases crop yields and the practice affects water and energy cycles at, above, and below the land surface. Until recently, there has been a scarcity of geospatially detailed information about irrigation that is comprehensive, consistent, and timely to support studies tying agricultural land use change to aquifer water use and other factors. This study shows evidence for a recent overall net expansion of 522 thousand ha across the U.S. (2.33%) and 519 thousand ha (8.7%) in irrigated cropped area across the High Plains Aquifer (HPA) from 2002 to 2007. In fact, over 97% of the net national expansion in irrigated agriculture overlays the HPA. We employed a modeling approach implemented at two time intervals (2002 and 2007) for mapping irrigated agriculture across the conterminous U.S. (CONUS). We utilized U.S. Department of Agriculture (USDA) county statistics, satellite imagery, and a national land cover map in the model. The model output, called the Moderate Resolution Imaging Spectroradiometer (MODIS) Irrigated Agriculture Dataset for the U.S. (MIrAD-US), was then used to reveal relatively detailed spatial patterns of irrigation change across the nation and the HPA. Causes for the irrigation increase in the HPA are complex, but factors include crop commodity price increases, the corn ethanol industry, and government policies related to water use. Impacts of more irrigation may include shifts in local and regional climate, further groundwater depletion, and increasing crop yields and farm income.

    The strong trends in climate change already evident, the likelihood of further changes occurring, and the increasing scale of potential climate impacts give urgency to addressing agricultural adaptation more coherently. There are many potential adaptation options available for marginal change of existing agricultural systems, often variations of existing climate risk management. We show that implementation of these options is likely to have substantial benefits under moderate climate change for some cropping systems. However, there are limits to their effectiveness under more severe climate changes. Hence, more systemic changes in resource allocation need to be considered, such as targeted diversification of production systems and livelihoods. We argue that achieving increased adaptation action will necessitate integration of climate change-related issues with other risk factors, such as climate variability and market risk, and with other policy domains, such as sustainable development. Dealing with the many barriers to effective adaptation will require a comprehensive and dynamic policy approach covering a range of scales and issues, for example, from the understanding by farmers of change in risk profiles to the establishment of efficient markets that facilitate response strategies. Science, too, has to adapt. Multidisciplinary problems require multidisciplinary solutions, i.e., a focus on integrated rather than disciplinary science and a strengthening of the interface with decision makers. A crucial component of this approach is the implementation of adaptation assessment frameworks that are relevant, robust, and easily operated by all stakeholders, practitioners, policymakers, and scientists.

  17. Sustainable agricultural water management across climates

    NASA Astrophysics Data System (ADS)

    DeVincentis, A.

    2016-12-01

    Fresh water scarcity is a global problem with local solutions. Agriculture is one of many human systems threatened by water deficits, and faces unique supply, demand, quality, and management challenges as the global climate changes and population grows. Sustainable agricultural water management is paramount to protecting global economies and ecosystems, but requires different approaches based on environmental conditions, social structures, and resource availability. This research compares water used by conservation agriculture in temperate and tropical agroecosystems through data collected from operations growing strawberries, grapes, tomatoes, and pistachios in California and corn and soybeans in Colombia. The highly manipulated hydrologic regime in California has depleted water resources and incited various adaptive management strategies, varying based on crop type and location throughout the state. Operations have to use less water more efficiently, and sometimes that means fallowing land in select groundwater basins. At the opposite end of the spectrum, the largely untouched landscape in the eastern plains of Colombia are rapidly being converted into commercial agricultural operations, with a unique opportunity to manage and plan for agricultural development with sustainability in mind. Although influenced by entirely different climates and economies, there are some similarities in agricultural water management strategies that could be applicable worldwide. Cover crops are a successful management strategy for both agricultural regimes, and moving forward it appears that farmers who work in coordination with their neighbors to plan for optimal production will be most successful in both locations. This research points to the required coordination of agricultural extension services as a critical component to sustainable water use, successful economies, and protected environments.

  18. A Systems Approach to Agricultural Biosecurity.

    PubMed

    Anand, Manish

    This article highlights the importance of systems approaches in addressing agricultural biosecurity threats. On the basis of documentary analysis and stakeholder interaction, a brief survey of agricultural biosecurity threats and vulnerabilities from global and Indian perspectives is provided, followed by an exploration of technological and institutional capabilities. Finally, a perspective on the agricultural disease diagnostic networks is provided, drawing instances from global developments. Technical barriers to agroterrorism are lower than those to human-targeted bioterrorism, and the sector is unique as even a very small disease outbreak could prompt international export restrictions. Key vulnerabilities in the agriculture sector stem from, among others, the structure of agricultural production; insufficient monitoring, surveillance, and controls systems at the borders and in the food chain; inefficient systems for reporting unusual occurrences and outbreaks of disease; and lack of sufficiently trained human resources capable of recognizing or treating transboundary pathogens and diseases. An assessment of technology and institutions pertaining to crop and animal protection management suggests certain gaps. Investment in developing new technologies for civilian application in agriculture, as well as for legitimate actions pertaining to defense, detection, protection, and prophylaxis, and in upgrading laboratory facilities can increase the agricultural sector's level of preparedness for outbreaks. To address potential threats and vulnerabilities of agroterrorism effectively requires the development of a comprehensive strategy and a combined, interagency approach, ideally on an international level. It is proposed that a systems-oriented approach for developing knowledge and innovation networks and strengthening skills and capacities would enable a more resilient agricultural biosecurity system.

    2008-01-01

    This paper is an introduction to the following series of papers that report on in-depth investigations that have been conducted at five agricultural study areas across the United States in order to gain insights into how environmental processes and agricultural practices interact to determine the transport and fate of agricultural chemicals in the environment. These are the first study areas in an ongoing national study. The study areas were selected, based on the combination of cropping patterns and hydrologic setting, as representative of nationally important agricultural settings to form a basis for extrapolation to unstudied areas. The holistic, watershed-scale study design that involves multiple environmental compartments and that employs both field observations and simulation modeling is presented. This paper introduces the overall study design and presents an overview of the hydrology of the five study areas.

  20. Lead in Urban Soils: A Real or Perceived Concern for Urban Agriculture?

    PubMed

    Brown, Sally L; Chaney, Rufus L; Hettiarachchi, Ganga M

    2016-01-01

    Urban agriculture is growing in cities across the United States. It has the potential to provide multiple benefits, including increased food security. Concerns about soil contamination in urban areas can be an impediment to urban agriculture. Lead is the most common contaminant in urban areas. In this paper, direct (soil ingestion via outdoor and indoor exposure) and indirect (consumption of food grown in Pb-contaminated soils) exposure pathways are reviewed. It is highly unlikely that urban agriculture will increase incidences of elevated blood Pb for children in urban areas. This is due to the high likelihood that agriculture will improve soils in urban areas, resulting in reduced bioavailability of soil Pb and reduced fugitive dust. Plant uptake of Pb is also typically very low. The exceptions are low-growing leafy crops where soil-splash particle contamination is more likely and expanded hypocotyl root vegetables (e.g., carrot). However, even with higher bioaccumulation factors, it is not clear that the Pb in root vegetables or any other crops will be absorbed after eating. Studies have shown limited absorption of Pb when ingested with food. Best management practices to assure minimal potential for exposure are also common practices in urban gardens. These include the use of residuals-based composts and soil amendments and attention to keeping soil out of homes. This review suggests that benefits associated with urban agriculture far outweigh any risks posed by elevated soil Pb.
