The CGIAR Research Program on Water, Land and Ecosystems (WLE)
The CGIAR research program on water, land, and ecosystems (WLE) addresses global food production challenges through ecosystem service-based approaches that enhance agricultural output and livelihoods. It emphasizes the need for coordinated efforts to achieve land degradation neutrality in regions suffering from severe soil degradation. The program also explores gender equity in agriculture and aims to promote sustainable agriculture that supports community prosperity and environmental health.
