Eastern and Southern Africa (ESA) is the region with the lowest percentage of households with coverage to at least basic water of all regions and also lags behind basic sanitation coverage. The analysis looks at access to services, institutional structures, funding sources (including from governments, donors and households), funding channels, and the quality and equity of funding to the sector. It builds on four deep-dive country assessments carried out in Burundi, Eswatini, Uganda and Zimbabwe, which, taken together, aim to influence planning, budgeting and advocacy toward greater and more effective allocation of resources for WASH.
