One of Africa's Great Lakes, Tanganyika is the second largest in the continent, behind Lake Victoria. Bordering the DRC, Tanzania, Zambia and Burundi, the lives of millions living on its shores are under threat as the lake's ecosystem changes.

Burundian refugees gather in the fishing village of Kagunga on the shores of Lake Tanganyika in 2015. Fishing yield has declined in recent years, partially because of unsustainable practices and an influx of displaced people settling in the region.

Rapid deforestation of surrounding hillsides have loosened the earth, causing an increase in sand and mud being washed into the lake.

This sand and mud smothers the lake floor in the shallows, where most of Lake Tanganyika's flora and fauna live.

The main reason for human resettlement is conflicts in the 1990s in Rwanda, Burundi and the DRC.
