Title: Africa Regional Centres of Excellence - ArcX: Water Component.
Main Objective: Strengthen water governance and resilience in Sub-Saharan Africa through research, capacity building, and inclusive solutions for sustainable water resource management and equitable access to WASH services.
Specific Objectives:
Conduct research on climate, hydrology, and the Water–Energy–Food–Ecosystem (WEFE) nexus;
Provide science-based recommendations for water management and environmental risk reduction;
Develop human capacity through training and mobility programmes for young professionals.
Hydrology and Climate: Studies on surface and groundwater under changing climatic conditions;
Water Management: Policy and decision-support for transboundary basin management;
WEFE Nexus: Cross-sectoral linkages among water, energy, food, and ecosystems;
WASH: Equitable access to water, sanitation, and hygiene services with gender-sensitive delivery mechanisms.
Target Groups: AUDA-NEPAD Networks of Water Centres of Excellence, regional organisations, river basin authorities, policy stakeholders, service providers, young professionals, and end-users.

This dataset provides a continent-wide, raster-based spatial representation of groundwater resources across Africa for the year 2011, modeled under a historical baseline climate scenario. It is design...
Surface water affects many aspects of our world: the exchange of heat, gas and water vapour between the planet's surface and atmosphere. Water is the engine behind the distribution, movement and migra...
Mangroves are trees or shrubs adapted to saline and brackish environments. They are found in the intertidal zone of tropical and sub-tropical coastlines. Mangrove forests are among the most productive...
The hydropower installed capacity indicates the amount of energy a hydropower plant can produce in its turbines. In 2016, hydropower accounted for 54% of the installed capacity in Eastern Africa, 58% ...
Water is a critical natural resource for both natural ecosystems and human subsistence. Some of the most immediate pressures on land that lead to degradation include diversion of surface waters and th...
Increasing water scarcity and water quality issues are serious constraints, especially for Northern Africa. A comprehensive assessment of spatial and temporal precipitation frequency is the initial st...
Chlorophyll-a concentrations (Chla) are an indicator of phytoplankton abundance and biomass in open waters. They can be an effective measure of trophic status and are commonly used to measure water qu...
Monitoring of sea surface temperature (SST) provides fundamental information on the global climate system and for the study of marine ecosystems. This layer compares the SST value of the last full mon...
