Lake Malawi and the Impact of Climate Change on Water Levels

12.2S 34.2E

April 23rd, 2013 Category: Climate Change, Lakes

Malawi – April 22nd, 2013

Lake Malawi (Lake Nyasa, or Lago Niassa in Mozambique), is an African Great Lake and the southernmost lake in the East African Rift system, located between Malawi, Mozambique and Tanzania. The third largest and second deepest lake in Africa, it is also the ninth largest in the world. It is reportedly the habitat of more species of fish than any other body of freshwater, including more than 1000 species of cichlids, and was officially declared a reserve by the Government of Mozambique in 2011.

Sustainable water resources development of Malawi needs a thorough assessment of the impact of climate change on the future water levels of Lake Malawi because Lake Malawi together with its outflowing Shire river water system is Malawi’s most important water resource for hydropower generation, water supply for industrial and domestic use in the city of Blantyre and its surrounding urban areas together with irrigation water in the Lower Shire Valley (LSV). Any changes in the hydrological or ecological behaviour of the lake will have far reaching consequences on the economy of Malawi.

The results of sensitivity analysis of the WBM of Lake Malawi to climate change have shown that water level will continue to drop following a decrease in the rainfall season and an increase in evaporation rates from the lake. It further shows that it is very unlikely for the water level to increase to a maximum height of 477 m amsl as was in 1980 (click here for more information).

Malawi – November 13th, 2012

Lake Malawi is an African Great Lake and the southernmost lake in the East African Rift system. This lake, the third largest in Africa and the eighth largest lake in the world, is located between Malawi, Mozambique, and Tanzania. It is the second deepest lake in Africa, although its placid northern shore gives no hint of its depth. This great lake’s tropical waters are reportedly the habitat of more species of fish than those of any other body of freshwater on Earth.

Fires in Southern Africa Near Lake Malawi

Malawi, Mozambique, Zimbabwe – October 10th, 2012

Dozens of fires burning in southern Africa contribute to a haze hanging over the region. Here, fires can be seen in Mozambique (above) and Zimbabwe (below), east and south of Lake Malawi. Popcorn clouds also dot the skies near the lake and the Mozambican coast.

Malawi and Zambia – September 3rd, 2012

Smoke from fires in central-southern Africa hovers over the land in Zambia and Malawi between Lake Malawi (upper right, on the Malawi-Mozambique border), Lake Kariba (lower left, on the Zambia-Zimbabwe border) and Lake Bangweulu (upper left). Surrounded by patchy clouds at the lower center is Lake Cahora Bassa, in Mozambique.

Lakes Malawi and Rukwa in East Africa

Malawi, Mozambique, Tanzania - November 22nd, 2011

Two large African lakes can be observed here: the brownish grey Lake Rukwa (upper left corner) and the elongated, dark blue Lake Malawi (also known as Lake Nyasa).

Lake Malawi is an African Great Lake and the southernmost lake in the Great Rift Valley system of East Africa. This lake, the third largest in Africa and the eighth largest lake in the world, is located between Malawi, Mozambique, and Tanzania. It is the second deepest lake in Africa.

Lake Rukwa is an alkaline lake in southwestern Tanzania, lying midway between Lake Tanganyika and Lake Nyasa at an elevation of about 800 metres, in a parallel branch of the rift system. The lake has seen large fluctuations in its size over the years, due to varying inflow of streams. Currently it is about 180 km long and averages about 32 km wide, making it about 5760 square kilometres in size.
