Dust Over Bab-el-Mandeb Strait

Red Sea – June 9th, 2013

Dust hangs over the Bab-el-Mandeb Strait, which connects the Red Sea (upper left) to the Gulf of Aden (right). The dust is most concentrated over the nation of Djibouti and southern Eritrea, by the entrance to the strait itself, although it also veils parts of Yemen, Ethiopia and Somalia.

Climate Change in the Lake Tana Basin, Ethiopia

Ethiopia – April 27th, 2013

Climate change has the potential to reduce water resource availability in the Nile Basin countries in the forthcoming decades. Scientists investigating the sensitivity of water resources to climate change in the Lake Tana Basin, Ethiopia, using outputs from global climate models, have predicted statistically significant declines in annual streamflow for the 2080-2100 period. This means that anthropogenic climate changes may indeed alter the water balance in the Lake Tana Basin during the next century (click here for more information).

Smoke Over Ethiopia and South Sudan – February 27th, 2013

Ethiopia – February 26th, 2013

Fires in Ethiopia and South Sudan release a cloud of smoke over the area. Several individual plumes of smoke can be individuated in the full image. The smoke does not blow northeast to Lake Tana, visible in the upper right quadrant, and also does not completely obscure some of the wetlands around the White Nile in South Sudan (lower left quadrant).

Lake Tana Environmental Issues, Ethiopia, and Dust Over Red Sea

12.1N 37.4E

January 30th, 2013 Category: Dust Storms, Lakes

Ethiopia – January 28th, 2013

Some dust can be seen blowing off the coast of Eritrea and over the Red Sea, towards the Dahlak Archipelago. Further south, in Ethiopia, the bright green waters of Lake Tana can be observed. The lake, which is the largest in Ethiopia and the main source of the Blue Nile, is under severe environmental threat from deforestation, soil and water erosion, sedimentation, increasing demand for water, pollution, and climate change.

Threats to Lake Tana and its catchment area have serious implications for environmental and human security in Ethiopia and raise other ecological and cultural questions as well. Lake Tana is the largest fresh water body in Ethiopia, accounting for 50 percent of the total inland waters in the country. The lake provides livelihood to over 3 million people living around it, as well as food security, and is a significant source of hydropower.

Changes in the lake and its watershed also have important international implications. A decrease in the quantity or quality of the outflow from Lake Tana may impact, the downstream riparian countries along the Nile, who rely heavily on these water resources for much of their agricultural production.

Ecologically, the lake area includes substantial wetlands, which provide a wide variety of ecosystem services, including habitat for fish and bird species, regulation of water flow, and mitigation of climate variability. All of these would be threatened by environmental degradation (click here for more information).

Plume of Dust Across Ethiopia and Sudan

December 27th, 2012 Category: Dust Storms

Ethiopia and Sudan – December 25th, 2012

Visible in the lower right hand corner of this image is Lake Tana, located in Amhara Region in the north-western Ethiopian Highlands. The lake is approximately 84 kilometers long and 66 kilometers wide, with a maximum depth of 15 meters, and an elevation of 1,840 meters. Near the lake is a plume of dust blowing towards the northwest, almost reaching the Nile River, which flows northward across Sudan on the left side of the image.
