This document provides an evaluation report of the GEF's support to Sierra Leone from 1998 to 2013. It begins with an overview of the GEF portfolio in Sierra Leone, which included 27 national projects, participation in regional and global projects, and support from the Small Grants Programme. The main conclusions are that GEF funding helped build national capacity for environmental management, but impacts were mixed and financial sustainability remains a challenge. Key lessons identified include the need for more coordination across projects and stronger government ownership.
