Lake Tanganyika
Why in news?
- Countries surrounding Lake Tanganyika—Burundi, DR Congo, Tanzania, and Zambia—launched a joint initiative to protect biodiversity, combat land degradation, and ensure sustainable management of Africa’s second-largest freshwater lake basin.
About Lake Tanganyika:

-
- Location and Geography:
- Lake Tanganyika is one of Africa’s Great Lakes, located within the Albertine Rift, the western branch of the East African Rift Valley.
- It is bordered by Tanzania (46%), the Democratic Republic of the Congo (40%), Burundi, and Zambia.
- The lake stretches 676 km in length and has an average width of 50 km.
- It covers an area of 32,000 sq. km and has a shoreline of 1,900 km.
- Formation:
- Lake Tanganyika began forming 9–12 million years ago, making it one of the oldest lakes in the world.
- It was shaped by tectonic activity due to the movements of the African Plate and the Somali Plate, which created deep basins.
- The rifting process caused by the East African Rift System led to the gradual formation of the lake.
- The central basin formed first, followed by the northern and southern basins, as the rift valley continued to expand.
- Ecological Significance:
- Lake Tanganyika holds 16% of the world’s available freshwater and is Africa’s deepest lake, with a maximum depth of 1,471 meters.
- It is home to over 350 fish species, including endemic cichlids, supporting local fisheries.
- The lake’s biodiversity includes crocodiles, hippos, and water birds, making it an important ecosystem for both aquatic and terrestrial wildlife.
- The water is alkaline, with seasonal mixing occurring primarily in the southern part, allowing nutrient circulation essential for fish populations.
- Causes of Land Degradation:
- Deforestation: Unregulated tree cutting for agriculture and firewood has led to soil erosion, increasing sedimentation in the lake.
- Overfishing: Intensive fishing, including the use of illegal nets, has depleted fish stocks, affecting the lake’s ecosystem.
- Pollution: Industrial waste, untreated sewage, and agricultural runoff have led to water contamination.
- Climate Change: Rising temperatures have reduced oxygen levels in deeper waters, disrupting aquatic life.
- Mining Activities: Unregulated mining around the basin contributes to water pollution and habitat destruction.
