Climate Change Issues for Etosha Pan, Namibia

18.7S 16.4E

April 20th, 2013 Category: Climate Change, Salt Flats

Namibia – April 20th, 2013

The Etosha pan is a large 20-kilometre-long (75-mile-long) endorheic salt pan forming part of the Kalahari Basin in the north of Namibia. The pan is protected due to its designated as a Ramsar wetland of international importance; however, temperatures in Namibia have been rising at three times the global average rate for the twentieth century, and scientists expect the climate to continue to become hotter and drier—which could reduce the range and number of wildlife supported by Etosha. If nothing is done to reduce heat-trapping emissions, the pan faces a net loss of around eight species of mammals by 2050.

Climate Change Affecting Wildlife in Etosha Pan, Namibia

Namibia – April 3rd, 2013

Visible at the top center of this image is the Etosha Pan, in Namibia. Although it is one of the harshest and most barren areas on Earth, the Pan and the surrounding sweetveld savannah plains are home to more than 114 mammal and some 340 bird species.

This animal life is sustained only because of underground springs that form waterholes on the outskirts of the pan. These waterholes allow animals to fight off the dry and the heat as they migrate across Etosha, seeking refuge from temperatures that can reach as high as 120 degrees Fahrenheit.

Without a subterranean water table and the numerous places where it reaches the surface, little game would have been attracted to the region in the first place. There are indications, however, that the climate may be changing. 1995 was the 18th year of below average rainfall in Etosha. Large herbivores, as a result, have become more widely dispersed in search of grazing, and the predators alsoseem to be ignoring their previous range limits to widen their search for prey. Lion pride structure has become loose, with individuals traveling huge distances.

Namibia – January 25th, 2013

One of the harshest and most barren areas on Earth, the Etosha Pan, the white area of salt flats visible in the upper right quadrant of this image of Namibia, seems to forbid life. However, the Pan and the surrounding sweetveld savannah plains are home to more than 114 mammal and some 340 bird species.

This animal life is sustained only because of underground springs that form waterholes on the outskirts of the pan. These waterholes allow animals to fight off the dry and the heat as they migrate across Etosha, seeking refuge from temperatures that can reach as high as 120 degrees Fahrenheit.

Climate Change Creating Harsher Conditions in Namib Desert, Namibia

Namibia – January 27th, 2013

Living in the Namib desert was never easy due to extreme temperatures and sparse vegetation, but signs that climate change may be worsening the already harsh conditions in this area of desert have led to concern over how local farmers will water crops.

Namibia is the driest country in sub-Saharan Africa, with annual rainfall varying between 30 millimetres (1.2 inches) in the desert to as much as 500 millimetres in the extreme northeastern Caprivi Region. Climate change may already be making the situation worse, with increases in temperature of around 1.2 degrees Celsius observed.

According to scientists, in recent years, hot temperatures are getting hotter, hot days of above 35 degrees Celsius are becoming more frequent and the number of cold nights decreasing. Rainfall seasons are already starting later and ending earlier, affecting subsistence farmers who grow staple foods (click here to read more).

Etosha Pan and Phytoplankton Near Namibia Coast

Namibia – December 3rd, 2012

Visible by the right edge of this image is the Etosha Pan, a large endorheic salt pan, forming part of the Kalahari Basin in the north of Namibia. The 120-kilometre-long (75-mile-long) lakebed is mostly dry mud coated with salt, as can be observed from its white color here, but after a heavy rain it will acquire a thin layer of water.

Moving westward, a faint phytoplankton bloom can be seen off the coast of Namibia, in the waters of the Pacific Ocean. The bloom appears more blue in color in the left left corner, and more green to the northeast, closer to the shore.
