The Kikuyu Escarpment Forest Reserve covers an area of 37,000 hectares. The forests provide important ecosystems service among them a critical watershed. However, the catchment faces serious threat of environmental degradation occasioned by encroachment into water catchments leading to water stress. To ensure sustainable financing for the protection of the forest catchment, the Kijabe Environment Volunteers (KENVO) in partnership with stakeholders from businesses, government, learning institutions and community institutions initiated payment for water ecosystem (PES) scheme. The water PES sought to address catchment degradation, poor land management, cultivation on riverbanks, increased water pollution and receding water levels on dams. The solution presents payment of water ecosystems services scheme at the catchment spanning over 3 years at Kikuyu Escarpment financed by Critical Ecosystem Partnership (CEPF).
