African Great Lakes contain 25% of Earth’s freshwater, endemic species face extinction

The Story in Brief

The African Great Lakes lie along the East African Rift and include Victoria, Tanganyika, Malawi, Turkana, Albert, Kivu and Edward. Together they hold over 25% of the world’s surface freshwater and support more than 50 million people across ten countries through food and jobs. Lake Victoria is the world’s second-largest freshwater lake by surface area; Tanganyika ranks second globally for both depth and volume. The lakes feed the Nile, the Congo and the Zambezi and host more than 10% of the world’s freshwater fish species. A global assessment published in Nature, based on over 20 years of work by more than a thousand experts, found the single highest concentration of threatened freshwater species around Lake Victoria. Crabs, crayfish and shrimp face the steepest extinction risk, with close to a third threatened, followed by freshwater fish, dragonflies and damselflies. Major pressures include rapid population growth, unsustainable fishing, pollution from towns and industry, sediment from deforestation and farming, habitat loss from land conversion, water extraction and dams. Climate change could worsen these risks, and experts say freshwater conservation must use tailored approaches.

The Indian Opinion

The article highlights an important scientific finding but at times uses attention‑grabbing comparisons, such as likening lake biodiversity to coral reefs, which may overstate ecological similarity. Calling the region “among the most threatened” reflects the Nature study’s results, yet it compresses varied conditions across ten countries into a single phrase. The assessment’s long timeframe and many contributors strengthen its credibility, but gaps in local monitoring and different governance capacities mean impacts and solutions will differ by lake and community. Readers should note the clearly identified human causes-pollution, overfishing, land use change and dams-while recognising that detailed, region‑specific action will be required.
