In West Africa, yam is a staple. But it saps the earth of nutrients, leaving the land too depleted to secure the region’s food supply. Scientists Beatrice Aighew and Chinwe Ifejika Speranza are leading on research to keep soils fertile and grow yam sustainably.

The footage was collected by scientists working side by side with communities around the globe, supported by the Swiss Programme for Research on Issues for Development (r4d programme), an initiative by the Swiss Agency for Development and Cooperation and the Swiss National Science Foundation. The r4d programme mobilizes the scientific community to support global development with their knowledge, creativity and innovative solutions.
