−|The project’s goal is to preserve the ecological functions and connectivity of the TRIDOM area, ensuring the long-term conservation of its protected areas system through an integrated, sustainable, and participatory management approach in the interzone between protected areas.
−Through this specific objective, the project promotes a land-use matrix that, once fully implemented across the region, will help conserve globally significant biodiversity through sustainable exploitation, while preserving it by designating land within the production forest as protected.
−The project supports the three governments in designing and implementing a coherent land-use plan that designates protected areas, permanent forest zones, and rural development areas. It also aims to strengthen resource exploitation control capacities, monitor trends in biodiversity and ecosystems through an effective law enforcement system, foster collaborative management frameworks with the private sector and local communities, especially indigenous populations, and establish an efficient and cost-effective monitoring system.
