A
new atlas documenting Africa’s rapidly changing landscape has published by the UN, featuring over 300 satellite images taken in every country in Africa. The before and after images, some of which span a 35-year period, show how development choices, population growth, climate change and, in some cases, conflicts are shaping and impacting the natural and nature-based assets of the region
Before: Lake Alemaya, Ethiopia 1986
After: The 2005 image underlines the loss of the Lake Alemaya due to siltation, irrigation demands and possibly by rising temperatures since the mid-1980s
