Popis: | Given the challenges presented by climate change, water shortages, and land degradation, sustainable agriculture approaches that increase farming systems’ yield and resilience are required more than eve, particularly in rainfed areas.The findings reported here derive from a regional collaborative project (http://www.sri-lmb.ait.asia/). More than 15,000 farmers participated in the field trials located in 33 districts of 11 provinces in the Lower-Mekong-Basin (LMB). The number of experiments conducted was more than 1,500. Relative to the pre-project baseline survey, project data show that System of Rice Intensification practices helped to improve conditions across the LMB region. Average rice yield increased by 52%, net economic returns were raised by 70%. Labour productivity increased by 64%; water productivity by 61%; and the efficiency of mineral fertilizer-use rose by 163%. The total energy input required for farming operations was decreased by 34%, while emissions of greenhouse gas were significantly reduced, by 14% with irrigated rice production, and by 17% per-hectare in rainfed cropping.The results of this farmer-participatory research characterize climate-smart agricultural practices that can promote household-food-security and support market-oriented development at low cost, especially in rainfed areas that have not figured prominently in development plans. |
