This session will focus on sharing insights, lessons learned, and challenges for achieving water security in the context of climate change. The session will draw recommendations from recent work in Nepal, a country with complex socio-economic and institutional settings and facing significant climate impacts, with consequences on communities, livelihoods, and economic development. Nepal’s social diversity is reflected in its population of 30 million people, which is composed of126 distinct caste and ethnic groups who speak 123 languages. The landscape is equally variedecologically; within a short north-south transect of 200 km, the country encompasses all the ecological zones from sub-tropical to arctic.
