Risk of Human induced desertification

 

  • 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.

LONDON, Feb 13 (Reuters) - Global warming will get worse as agricultural methods accelerate the rate of soil erosion, which depletes the amount of carbon the soil is able to store, a United Nations' Environment Programme report said on Monday.

Soil contains huge quantities of carbon in the form of organic matter. which provides nutrients for plant growth and improves soil fertility and water movement.

The top metre of soil alone stores around 2,200 billion tonnes of carbon, which is three times the level currently held in the atmosphere, said the UNEP Year Book 2012.
