ABSTRACT

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.

摘要

鉴于气候变化，水资源短缺和土地退化带来的挑战，尤其是在雨育地区，迫切需要采用可持续农业方法来提高农业系统的产量和抵御能力。本文报道的研究结果来自一项区域合作项目（http： //www.sri-lmb.ait.asia/）。超过15,000名农民参加了位于湄公河下游地区11个省的33个地区的田间试验。进行的实验数量超过1,500。相对于项目前的基线调查，项目数据显示，稻米集约化生产实践有助于改善整个LMB地区的状况。大米平均单产提高了52％，净经济收益提高了70％。劳动生产率提高了64％；水分生产率提高61％；矿物肥料的使用效率提高了163％。农业运营所需的总能源输入减少了34％，温室气体排放量显着减少，灌溉水稻生产减少了14％，雨养作物每公顷减少了17％。这项农民参与研究的结果具有气候智能的农业实践的特征，可以以低成本促进家庭粮食安全并支持以市场为导向的发展，特别是在雨水养育地区，在发展计划中没有特别重视。
