Orange and red show the areas where the risk of human induced desertification is higher. As it can be immediately seen, the most affected areas are along the equator line in Africa. Developing countries such as India and the Middle East and Eastern Europe are also thought to be affected.
This also goes together with natural deforestation and desertification.
Desertification and droughts are major causes of ecosystem losses and species mass migration or extinction.
The world's biodiversity is down 30 percent since the 1970s, according to a new report, with tropical species taking the biggest hit. And if humanity continues as it has been, the picture could get bleaker.
