Although the disaster restoration in the agricultural land and rural villages has progressed since the 2004 Chuetsu Earthquake, potential small-scale damages of the agricultural infrastructure have been continuously coming to surface. The notable difference between the earthquake disaster and other disasters is that the former induces extensive ground damages which, in turn, lead to a long-term continuation of small-scale damage emergence. However, there exists no measure devised to deal with those small-scale damages due to the difficulty in technically proving the relationship between the damages and the earthquake even though the damages are actually caused by the earthquake. Although it has been pointed out that longer-term restoration measures are necessary to cope with the peculiar characteristic of a earthquake disaster, these are not realized in practice owing mainly to the unavailability of the secular change data of damages. In this research, the damage characteristics in the Chuetsu area were clarified through the analysis of tracking records of the Small-scale Disaster Restoration Project (SDRP: In Japanese "Tezukuri-tanaoshi-tou-shien" Project), and the results of questionnaires for the farmers. In conclusion, a proposition was made on long-term measures for the disaster restoration after the occurrence of a large-scale earthquake.
