How fishers are responding to climate change

Climate change is increasingly affecting fisheries resources in the African Great Lakes. For example a recent study concluded that decline of fish yield in Lake Tanganyika in due to climate change not over fishing. Another study, which was an extensive review of the influence of climate change on inland fisheries in Africa, by myself and colleagues at the National fisheries Resources Research Institute, Uganda, found impacts of climate change on all aspects of the fisheries.  Fishers have to adapt to increase the resilience of their livelihoods.

In this picture, a former fisher on Lake Wamala, Uganda, an environmental change hot spot stands near a tree at his home on which he hanged fishing gear after turning to high value crops and livestock.

Fishers are undertaking several ways to respond to climate change impacts on fisheries. You can find more insights on how fishers are adapting in a blog I wrote some time back for the Global Landscapes Forum.

The documentary below, which is a production of the National Fisheries Resources Research Institute that was  developed by a team I was part of presents in detail using a case study, how climate change is influencing aquatic systems, fish yield, and livelihoods of fishing and riparian communities and how they can adapt.
