West and Central Africa

West and Central Africa is heavily dependent on subsistence agriculture, with low productivity and food insecurity affecting nearly 50% of the population. Rapid urban growth has led to inadequate infrastructure and sanitation, causing land degradation and water pollution.

The region is highly vulnerable to climate change. Increasing temperatures, accompanied by erratic rainfall and prolonged dry spells and floods, are likely to reduce crop yields with serious implications for food security at a time of significant population growth: West Africa’s population of over 400 million is set to more than double by 2050.

IWMI in West and Central Africa

IWMI works closely with countries in the Economic Community of West African States and regional initiatives to respond to water challenges and priorities. Our partners include national and local governments, research institutes, universities, private sector enterprises, civil society and nongovernmental organizations, farmer associations and development organizations.

IWMI’s work in West and Central Africa focuses on improving water management, agricultural resilience, and climate adaptation. Through initiatives like AICCRA, IWMI helps farmers adapt to climate impacts and improve productivity.

IWMI also enhances irrigation and mechanization through innovation labs for small-scale irrigation, boosting agricultural productivity in water-scarce regions. Digital tools like DIWASA optimize water use, while policy advocacy and social research promote sustainable practices and equitable access to resources. These efforts contribute to building resilience and food security in the region.
