The TWB-MRB project was a collaborative effort between Florida International University (FIU), WWF Eastern and Southern Africa Regional Programme Office (WWF-ESARPO), World Vision International, CARE Tanzania, and the Mara River Water Resource Users Association (MRWUA) to support numerous governmental and local partners in the development and implementation of a basin-scale integrated water resources management plan in the trans-boundary Mara River Basin of Kenya and Tanzania. The project began in October of 2005 and extended through September of 2012.
