Climate Change and Botswana’s Rainfall and Temperatures – May 10th, 2013

20.6S 25.3E

Botswana – May 10th, 2013

This image shows two important areas of Botswana: the Okavango Delta (upper left) and the Makgadikgadi Pans (right). It is predicted that Botswana will become hotter over the next few decades, with an expected increase of 2°C by 2050—a rate of warming of 0.27°C per decade. It is also predicted that the spatial and temporal distribution of rainfall will be disrupted by climate change.

By 2050 there will be an annual decrease in rainfall of 5 percent in the northern and western regions of the country, while southeastern regions are expected to experience a 5 percent increase in annual rainfall. During the rainfall seasons, it is expected that there will be a 10–20 percent increase during the peak rainfall months (December to February), while other months will yield reduced rainfall. The rainy season will be shorter and less reliable due to climate change, and it is expected that most rain will fall as short, sharp events. It is expected that an increase in temperature would equal an increase in the rates of evaporation and transpiration (click here for more information).

Okavango Delta and Makgadikgadi Pans, Botswana

Botswana - April 15th, 2011

The green, broom-shaped Okavango Delta, the terminus of the Okavango River and one of the world’s largest inland water systems, can be observed on the left side of this image.

Millions of years ago the Okavango river use to flow into a large inland lake called Lake Makgadikgadi. This lake has now dried up and become the Makgadikgadi Pans, a large series of salt flats. The pans appear whitish grey and can be seen at the lower right.

 

Lakes, Floodplains and Salt Pans in Southern Africa

Botswana - February 18th, 2011

This image reaches from Angola (upper left) to Zambia (upper right), and to Botswana (lower left) and Zimbabwe (lower right). Several bodies of water and other interesting geographical features can be observed across the image.

Situated in the lower left quadrant is the Okavango Delta, the inland delta formed at the end of the Okavango River. East of the delta are several greenish white areas, the salty Makgadikgadi Pans. North of the delta lies the Barotse Floodplain. East of the floodplain is Lake Kariba, appearing silvery green in color due to sun glint.

Vegetation Index of Land Around Barotse Floodplain and Okavango Delta, Central Southern Africa

Angola, Zambia, Botswana, Zimbabwe - February 18th, 2011

The full version of this FAPAR image stretches across parts of Angola (upper left), Zambia (upper right), Botswana (lower left) and Zimbabwe (lower right). The land shows a generally good vegetation index, indicated by the mostly green false-color of the image.

However, several areas of high activity (rusty red) and low photosynthetic activity (yellow) can be seen across the image as well. The less active areas can be noted southeast of the Okavango Delta (bottom center of thumbnail) as one moves towards the Makgadikgadi Pans, and to the west of the Barotse Floodplain (above center).
