Central America is undergoing an important transition. Urban populations are increasing at accelerated speeds, bringing pressing challenges for development, as well as opportunities to boost sustained, inclusive and resilient growth.

Water insecurity—ranging from chronic water scarcity to lack of access to safe drinking water and sanitation services, to hydrological uncertainty and extremes (floods and droughts)—can cause severe disruptions and compound fragilities in social, economic, and environmental systems.

This research focuses on incorporating a representation of water supply and infrastructure costs into an energy systems model (SATIM-W) to better reflect the interdependent nature of the energy-water nexus in South Africa and the water supply challenges facing the energy system.
