In a country where four out of every five people live off the land, community-based conservation is an absolute necessity. And in Tanzania, it is yielding big wins for wildlife and biodiversity. Wildlife Management Areas, governed by multiple villages, are a proven tool for increasing biodiversity on the land, and improving the chances that nature will recover.

Tanzania's Ecology

In Tanzania, the movement of wild animals is just as important as the animals themselves. Here, ancient migrations define the wildlands and shape the ecological trajectory of this majestic landscape. Tanzania’s efforts to incorporate local people in conservation have created sustainable processes in the human world too. While the landscape has suffered due to extractive industry, there is reason to hope for Tanzania’s future.
