1972 2005
There are some amazing new photographs here of the changes which have happened in recent years in Africa. The atlas was compiled by the United Nations Environment Programme (UNEP) Here you can see the effects of dam building on the river Nile. The erosion at the coast is quite dramatic. Other great changes included tree loss and land degradation caused by refugees in the Sudan and the loss of Cameroon's rainforest to rubber and palm plantations. The biggest factor contributing to the changes is the rise in Africa's population to 965 million. You can see these photos here in the Guardian and also read about it here in the Times.
