Le lac Victoria : le plus grand lac tropical du monde

Lake Victoria: The World’s Largest Tropical Lake

One of the most interesting and perfectly situated lakes in the heart of East Africa is Lake Victoria. Lac Victoria is the largest tropical lake in the world, spanning the borders of three countries – Kenya, Tanzania, and Uganda. It is one of the best areas to be in, with several attractions and activities, and some of these activities include sailing on the water, fishing and other activities on the lake.

The largest part of this freshwater body is found in Tanzania, and altogether it spans approximately 68,800 km2. Lake Victoria is an integral part of East Africa’s rich cultural heritage and natural biodiversity and is famously known as the source of the Nile. Lake Victoria is the source of the River Nile, the river that is believed to be the longest in Uganda and Africa at large.

On a découvert que le lac Victoria s'était formé il y a environ 400 000 ans par le processus appelé déformation vers le bas des terres situées entre les deux bras du fleuve. Vallée du Grand Rift, whereby westward-flowing rivers were dammed by an upthrown crustal block, reversing their flow backwards into the down-warped land.

In 1858, the search by Europeans for the source of the Nile led to the sighting of the lake by the British explorer John Hanning Speke, who named the lake in honour of Queen Victoria of England. A detailed survey of the lake was made by Sir William Garstin in 1901; however, the lake was formerly known to the Arabs as Ukerewe and to the Baganda as Nalubaale.

Lake Victoria is one of the African Great Lakes, and it is the continent’s largest lake, the largest tropical lac in the World, and the second-largest freshwater lake in the world in terms of surface area. Numerous important rivers flow into Lake Victoria, such as the River Mara, Kagera, Yala, Nyando, Bukora and Katonga, while the White Nile is the only river flowing out of Lake Victoria.

Today, Lake Victoria, with its resources, supports the economies of Kenya, Tanzania and Uganda, while the Nile River support numerous countries where it passes, such as Egypt. The lake provides a greater percentage of hydropower for Uganda, Burundi and Rwanda, and also water supply for major urban centres like Kampala, Kigali, Mwanza, and Kisumu.

Faune sur le lac Victoria

Le lac Victoria abrite plus de 500 species of fish, and it is famed for its diverse fishery. The most common fish species are the Nile perch and the tilapia, that have attracted fishing industries and numerous communities while depending on the lake for survival. Lake Victoria’s rich biodiversity is a testament to the delicate balance of its ecosystem, supporting an array of wildlife including the Shoebill stork, African helmeted turtle, Freshwater crab, Giant Otter Shrew, Marsh Mongoose, and hippos.

And various reptiles like the Nile crocodile, whereas its vast shoreline harbours dense forests and wetlands, providing habitat and breeding grounds for various birds and animal species.
