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.
