The IW:LEARN4 project has 5 components aimed at strengthening knowledge management for transboundary waters management. It will support harvesting and disseminating project results, facilitate knowledge sharing between projects, expand communities of practice, promote results to non-GEF actors, and launch tools to improve portfolio performance. Key activities include improving the IW:LEARN website, project twinning, training workshops, economic valuation guidance, and online courses. The $4.9 million project will be implemented from 2014-2018 by CI, GWP, IUCN, TNC, UNEP, UNESCO, UNIDO, and WWF.
