Water Availability and Agricultural Adaptation Options of the Koshi Basin under Global Environmental Change
Global environmental changes are likely to affect the components of the hydrological cycle which in turn will affect the spatial and temporal distribution of water availability in the region, although uncertainties about the rate and magnitude of climate change and potential impacts prevail. It is generally agreed that climate change is gradually and powerfully changing the ecological and socioeconomic landscape in the Himalayan region, particularly in relation to water, with significant implications for mountain communities and livelihoods as well as downstream user groups and communities. The basins of the ten rivers originating in the region are inhabited by 1.3 billion people that depend on water resources for their livelihoods, dominated by agriculture. Therefore, it is important to understand how the global environmental change is likely to affect the temporal and spatial distribution of water availability and especially the impact on the agruculral sector. This project is being carried out in the transboundary Koshi basin, which is shared between China, Nepal and India.
