GTZ has commissioned the German Consulting firm GFA to implement the project component "Sustainable Development" within the "Protection of nature" project in Bayanga (Dzanga Sangha). The aim of the project is ecological and economic stability within the region, benefiting both the people and the fauna. Under this framework plans for village development have been put in place and specific measures (projects) have been achieved in collaboration with the population and the local administration (the construction of schools, health centres, water pumps, wells, agricultural training). Together with WWF, GFA are developing eco-tourism to generate funds for conservation and to create income for the (local) population. The construction of Doli Lodge hotel was financed by GTZ and represents a masterpiece of the eco-tourism approach.
