Science-policy bridges over troubled waters: making science deliver greater impacts in shared water systems

The GEF IW:Science synthesis report, brings together the findings and efforts of the IW System Type Working Groups (Groundwater, Lakes, Rivers, Land-based Pollution Sources and, Large Marine Ecosystems and the Open Ocean). This report provides a global perspective on the state of challenges and pressures facing transboundary water systems, both freshwater and marine. The context of the synthesis is the need and effective use of science to address these challenges and the translation of such science use to policy for multi-country management of shared water resources.
