Abstract
Climate change could have a critical impact on agriculture in Nepal due to dry-season water shortages, and changes in the variability of water availability and associated uncertainty. This makes water storage systems (most notably ponds and tanks) increasingly important. This report explores the potential role of small-scale water storage infrastructure in two subbasins within the larger Koshi River Basin in central and eastern Nepal, yet shows that upscaling such infrastructure requires an appreciation of the other drivers of change in agriculture aside from climate (e.g., rising cost of living and poor terms of trade for agriculture). It also identifies the social relations and dynamics (distribution of land, water and labor) which could mediate the success of future interventions. It is clear from the research that, while small-scale water storage has the potential to significantly strengthen livelihoods in the Nepali hills, it is necessary to tailor projects to the existing political-economic context.

Population pressure and increasing water competition in a changing climate require us to take stock of the availability and use of water across scales. Water availability not only influences farmers’ commercial prospects but also irrigation-related enterprises and agri-businesses. Greater water scarcity could jeopardize irrigation and agricultural markets while excessive water use can lead to declining ecosystems, water quality and soil health. IWMI advises development partners and the public and private sectors on all aspects of water resource availability and use through a variety of advanced modeling and remote-sensing products and tools, including
The ability of farmers to engage in or expand irrigation depends on the prevailing socioeconomic, ecological and political contexts, which are often complex, non-linear and changeable. Overcoming systemic barriers to farmer-led irrigation development while taking advantage of existing opportunities
A lack of affordable credit, particularly for women and resource-poor farmers, is one of the main barriers to expanding farmer-led irrigation in low- and middle-income countries. But
Scaling farmer-led irrigation requires strengthening human capacity and knowledge exchange among all actors and stakeholders involved. IWMI takes an action research approach, working with national and international research institutions, governments, extension agents and public and private organizations to co-develop the scaling ecosystem and strengthen capacity to drive scaling networks and collective action.
