Improving Management of Natural Resources for Sustainable Rainfed Agriculture in Northeastern ThailandNSenanarongauthorPCheuwchoomauthorCLusanandanaauthorSTangpoonpoauthorSAtichartauthorAPongkanjanaauthorPSrihabanauthorTSinghapongauthorAPatanothaiauthorBToomsanauthorSRuaysoongnernauthorT JRegoauthorLands of northeastern Thailand are sloping and fragile. A large proportion of these soils are degraded due to soil erosion. Degraded soils are one of the major constraints for agricultural production in this region. ICRISAT in collaboration with the Department of Agriculture, Land Development Department, and Khon Kaen University, Thailand started a project in 1999 with the financial support from the Asian Development Bank to improve the management of natural resources for sustainable rainfed agriculture through integrated watershed approach. This paper summarizes all the research work carried out for three years during the project period. This includes selection of benchmark site in the ecoregion, baseline surveys, establishment of monitoring devices and various interventions in cropping systems, land and water management and fertility management areas, and human resource development. The initial results of research indicate a reduction in soil erosion and improvement of crop yields due to various interventions. There is sufficient scope to scale up this work in the ecoregion.
