Where does it Occur?
As you can see from the image (left), "Water Stress by Country", that the most extreme (> 80%) places being affected by water stress are Mongolia, the top of Africa, Saudia Arabia and parts surrounding it. Countries like Australia, Africa and lower Northern America has high water stress (40-80%) as well. However, majority of South America, part of Indonesia and the middle of Africa has low water stress (< 10%) ratio of withdrawals to supply. In this map, the middle of Africa, Peru, Chile and around India, economic water scarcity occurs. The top of Africa, a section of Australia and near Russia has physical water scarcity. Places with little or no water scarcity like Brazil, Argentina, parts of Russia and Australia, Canada and the United States although they have little water scarcity are still at very high risk to become vulnerable in the future. |
