The CGIAR Research Program on Water, Land and Ecosystems (WLE), a global research-for-development program connecting partners to deliver sustainable agriculture solutions, came to an end in 2021. Over the course of its ten-year journey, the program operated in over 60 countries, with more than 300 partners and completed over 200 projects. These activities made significant contributions to enhancing our natural resources and directly benefitted millions of lives across the Global South.

The program was led by the International Water Management Institute (IWMI) and partners as part of CGIAR, a global research partnership for a food-secure future.

The practical and science-driven innovations that WLE developed offer countries and farming communities the tools to address critical development challenges and transition to more productive, sustainable and resilient food systems. They include:

Crucially, WLE's emphasis on the importance of ecosystem health as a foundation of agricultural production also contributed to a global paradigm shift in agricultural research for development – reflected during discussions at COP 26 and the UN Food Systems Summit in 2021.

The Program's research also informed the transition to One CGIAR – a new partnership that integrates CGIAR's knowledge, assets and global presence, ensuring that CGIAR innovations are deployed faster and applied over a larger scale at a reduced cost. Food, land and water systems are integral to the One CGIAR mission and WLE research influencedthe development of several One CGIAR initiatives, including Nexus Gains, Agroecology, MITIGATE+ and Nature Positive Solutions.

Although the program may have closed, its research will continue to influence future research planning and investments – and help strengthen our collective response to the climate crisis and the needs of climate-vulnerable communities across the Global South.

WLE's impacts and achievements were shared during a Legacy Symposium organized before the program's closure in December 2021.
