Thick Smoke Across Central Africa

DRC, Tanzania, Zambia – June 26th, 2013

Red and yellow markers indicate the locations of hundreds of fires burning in the Democratic Republic of the Congo, Tanzania and Zambia, in central Africa in late June. Smoke from the fires, which were probably set to manage land, creates a hazy veil across the image. While fire helps enhance crops and grasses for pasture, this air quality-degrading smoke can be dangerous to human and animal health.

Correlation Between Climate Change and Tectonic Activity by Lake Rukwa, Tanzania

Tanzania – June 26th, 2013

Scientists have found a correlation between climatically induced lake level change in Lake Rukwa, seismo-tectonic activation of the regional fault network (underneath Lake Rukwa and the Kanda fault between Lakes Rukwa and Tanganyika) and the timing of the recent strong volcanic eruptions in the Rungwe Volcanic Province.

This relation is explained taking into account that Lake Rukwa is very sensitive to climate change as it occupies a flat depression and its overflow outlet is 180 m above its present-day level. Its lake level rises rapidly when the climate becomes more humid. Increases in lake level mean an increase in the load in the basin and perturbation of the ambient tectonic stresses (click here for more information).

Fires West of Lake Tanganyika, DRC and Tanzania – June 26th, 2013

DRC, Tanzania, Zambia – June 26th, 2013

Dozens of fires are burning in the Democratic Republic of the Congo, Tanzania and Zambia, in central Africa in late June. The fires, most of which are burning in grass or cropland, are indicated by red markers. Separating the Democratic Republic of the Congo and Tanzania is the large Lake Tanganyika. More smoke is visible west of the lake than to its east.

Fires Blazing Across Tanzania and DRC

DRC and Tanzania – June 19th, 2013

Hundreds of fires can be seen burning in the Democratic Republic of the Congo (left) and Tanzania (right), west and east of Lake Tanganyika. Such blazes are set every year during the dry season in Central Africa. Residents burn away scrub and brush annually in the woody savanna to clear land for farming and grazing.

Lake Malawi and the Impact of Climate Change on Water Levels

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).
