Figure 8: East Africa drought crisis Dr Chris Funk has no doubt that climate change is making things worse in the East African drought crisis – and believes Somalia is a warning to the rest of the world The climate in Somalia is difficult to assess because of the political and social situation, but they’ve had almost no rainfall in many areas. There are two rainy seasons in East Africa, one in October to December and another one in March to May. The March to May one has seen a really big decline – one of the most concerning rainfall trends in the world. In terms of farming, the March to May season tends to be the more important time of year. But when you have two seasons in a row that are bad, a) Define the common geographic meaning of the term ‘drought’. (1) that can be a real nightmare. Three bad seasons in a row have placed millions in peril. The temperatures have also been going up, significantly since the beginning of the 20th century. b) Explain why “There are two rainy seasons in East Africa, one in October to December and another one in March to May.” (2) It’s well known that if you’re growing corn and the temperatures go up over 30C, that’s bad for production. c) We alsoaknow, Create that to flow chart as explore temperatures go up, that the economic, lowers the birthweight environmental and social of children and increases the rates of severe malnutrition. impacts of drought in Africa. And when there is a rainfall shortage, (6) you get more evaporation from the land, so you’ll run out of water sooner. Satellite[9] vegetation data shows us the conditions on the ground really well, and going back 14 years 2.3 we can say this is the Johannesburg worst drought that we’ve seen in a lot of these places.

Explain what is meant by the terms ‘inclined’ and ‘strata’? (2) c) Draw a diagram to show this mountain range as it would appear on a topographical map. Label Pretoria to show its relative location (4) [10] 2.4 Refer to Figure 10: a landscape in Namibia, on page two of the colour insert. 2.4.1 Identify this type of landscape.
