Today is "World Day for Combating Desertification and Drought". In 1994, the UN dedicated 17 June to this important global issue in Resolution A/RES/49/115. The motto this time is "Don't let our future dry up". It aims to raise awareness of the need to do something about water stress and desertification. Parts of Europe are also already affected by water stress.Spain in particular has been affected for several years. The irresponsible use of water in agriculture and in tourist regions is taking its toll. Much worse is the situation in large parts of Africa. In many areas the deserts are expanding because the earth is dry and the groundwater level is too low. Dry and salty soils offer no habitat for most plants. Prof. Willem lists drought-resistant plants in his blog and many other interesting articles on the subject of desertification.
