I can really only speak to conservation to Congo. One thing I've noticed is that conservation organizations in DRC take on a lot more responsibilities than just wildlife conservation. In Virunga National Park, for example, the park has built and operates a power utility to provide an alternative to charcoal. This is made up of four run-of-the-river hydroelectric plants, hundreds of kilometers of distribution lines (high and medium tension), and smart meters to connect customers.
