New REAL-Water activity: Water Sustainability in Southern Madagascar

REAL-Water to coordinate data and actions for the sustainable development of water resources in arid Southern Madagascar.

In Madagascar, there are significant disparities in access to essential water and sanitation services. Currently, only about half of the population (54.4%) has access to vital water services, and just over 10% have access to necessary sanitation services. The situation is particularly challenging in Southern Madagascar, where various development issues, such as population growth, changes in land use, and worsening dry-season water shortages, are present. These difficulties are exacerbated by poverty, which hinders water resource development, leads to poor infrastructure, and contributes to food insecurity. 

To guide regional programming that considers the development and humanitarian requirements, USAID Madagascar has commissioned REAL-Water to assess water resources and infrastructure needs. The program will entail specific activities, including a literature review of water development activities, data collection on existing and planned water infrastructure, analyses of remaining water resources and infrastructure needs, and planning for future investments.

The six districts of interest covered in the assessment are shown on an I-digital elevation model (from the Shuttle Radar Topography Mission). Small gray and green polygons indicate areas of human settlement (“Settlement Extents”) from the GRID3 DATA HUB. Each settlement extent type (built-up area, small settlement area, and hamlet) is included, with built-up areas depicted in green).
