 In the thick forests of northern Democratic Republic of the Congo, Sitzyang Gambi, a place of high historical value that was once home to the largest tropical agriculture research center in the world. Now a biosphere reserve, it includes 250,000 hectares of tropical forest, a valuable island of conservation in a fast-changing landscape. But rapid population growth is putting ever greater pressure on this once impenetrable wilderness. This is why C4 and its partners, supported by the European Union, launched the FOREI project, aimed at protecting the biodiversity of Yang Gambi, while at the same time improving the living conditions of the local populations, ensuring that forests continue to thrive for generations to come.
