【摘要】 尼泊尔山区农业用水以雨水和山泉水(地下水)为主,灌溉设施普遍匮乏。在全球气候变化影响下,极端天气过程不断呈现,长期干旱和短时暴雨对农业生产的影响日益严重,直接影响农户生计安全,特别是纯农型的农户,面临更多的生计适应性挑战。柯西河(Koshi River)发源于中国西藏,流经尼泊尔进入印度,其流域的中上游至中下游是尼泊尔重要的农区,农业水资源的可利用性非常重要。通过统计分析法和生计适应链框架相结合,分析科西河流域水资源可用性,阐明科西河流域水资源变化特征,解决农户生产和生活用水问题,针对农户生计潜在水危机风险,提出农户生计适应性链框架及适应对策。更多还原

【Abstract】 Agricultural water in mountainous areas of Nepal is mainly rainwater and mountain spring water( groundwater),and irrigation facilities are generally deficient. Under the influence of global climate change,extreme weather processes continue to emerge. Long-term drought and short-term rainstorm have increasingly serious impacts on agricultural production,directly affecting the livelihood security of rural households,especially those who are pure rural households,and facing more challenges of livelihood adaptability. The Koshi river originates from the Tibet of China and flows through Nepal to India. The upstream to downstream of the central Koshi River Basin is an important agricultural region in Nepal,and the availability of agricultural water resources is very important. Through the comprehensive analysis of the availability of water resources,in this research the change characteristics of water resources were clarified in the Koshi river basin,and the problems of production and domestic water utilization of households were solved,and the framework of the livelihood adaptability chain and countermeasures were put forward according to the potential water crisis risks of rural households’ livelihood.更多还原
