The 2017 CGIAR annual report features some success stories from WLE, including the establishment of a new Sri Lankan sanitation policy that turns septic waste into a resource, and the work of the Groundwater Solutions Initiative for Policy and Practice (GRIPP) in promoting sustainable groundwater use. The WLE publication, Global Sequestration Potential of Increased Organic Carbon in Cropland Soils, was also featured.
