The document discusses the need for collaboration across sectors and regions to address the energy-water-land nexus in Central Asia. It notes that by 2050, there is estimated to be a 37% gap in water supply and demand under current practices. Climate change will increase uncertainty around water availability both between and within seasons. Regional energy trading and renewables will also impact water availability. The Asian Development Bank's technical assistance aims to develop the CAREC Water Pillar to build capacity and facilitate dialogue and joint initiatives around integrated water-energy planning, shared water infrastructure, and applied research. The vision is for a sustainable, climate-resilient and water-secure region with shared benefits.
