A CLEWS Nexus Modeling Approach to Assess Water Security Trajectories and Infrastructure Needs in Latin America and the Caribbean

This working paper presents an up-to-date and prospective assessment of water security throughout the LAC region with a focus on infrastructure needs, to aid in strategic thinking towards planning and management in key water-using sectors such as agriculture, energy and water supply. This assessment is grounded on a physically-based analysis of water supply and demand, highlights the climate-land-energy-water-socioeconomics (CLEWS) nexus contributions to water security in the region, and addresses uncertainty in projections and their implications through a variety of potential future scenarios of climate change and socioeconomic development in the region.
