People in the four countries bordering Lake Tanganyika rely heavily on fishing for both food and income. Some 1 million people earn their livelihood by fishing,3,4 and lake fish account for 25 to 40 percent of the animal protein supply for people living nearby.2 As a result of warming temperatures over the last century, biological activity in the lake has declined, threatening the sustainability of Lake Tanganyika's fishing industry.
- Since 1913, the surface waters of Lake Tanganyika have warmed by 1.6 to 2.3° F (0.9 to 1.3° C).5,6
- Rising temperatures are associated with a decrease in primary productivity—life activity at the base of the food chain—of 20 percent or more.5,9,10,11
- Given a mid–level scenario for future emissions of heat–trapping gases—primarily from the burning of coal, oil, gas, and trees—East Africa could warm by 5.4 to 6.3° F (3.0 to 3.5° C) by the end of this century, causing further declines in Lake Tanganyika's ecosystems.15,16
