Lake Tanganyika is an African Great Lake. It is the second oldest freshwater lake, second largest by volume, and second deepest in the world. It is also the longest freshwater lake in the world and accounts for 16% of the world’s available fresh water. Tanzania possesses 46% of the lake that is shared with the Democratic Republic of Congo, Burundi, and Zambia. Lake Tanganyika is home to about 250 species of Cichlid fish, Zambian hinged terrapins, and Nile crocodiles, including the giant Gustave and approximately 800 indigenous communities. It is estimated that 25-40% of the protein in the diet of the approximately one million people living around the lake comes from lake fish. However, the lake and its aquatic and human life are suffering from agricultural pollution, deforestation, destruction of wetlands, sand excavation, domestic sewage, and waste from livestock and palm oil factories. Tanzania Lake Tanganyika Waterkeeper, the first in the country, provides education to promote and implement environmental policies that reduce water and environment pollution.
