About this project


The aim of this project is to develop a long-term source of funding for the Mbe watershed based on payments for the ecosystem services provided by this important watershed to the capital city Libreville and surrounding areas. The project will undertake the quantification and valuation of those services for the development of a system of reasonable charges that guarantee the continuity of those services. Based on hydrological and economic studies, the parties will design a payments system for adoption by contract which ensures that the quantity and quality of water provided by the watershed are not threatened. In exchange, Monts de Cristal NP, management bodies, local communities and other stakeholders will receive financial resources to invest in management activities that lead to protection of this valuable resource.


Design a sustainable financing mechanism for long-term protection of the Mbé River forested watershed, while strengthening the legal, policy and institutional framework necessary to ensure its adoption and successful implementation.
