“desertisation”. The fact is that the United Nations General Assembly had picked up on a French usage, as is so often required by the complexities of the modern world. It was the great drought in the Sahel (1967-72) spreading devastation through Francophone Africa that had brought...
Sahel, semiarid region of western and north-central Africa extending from Senegal eastward to Sudan. It forms a transitional zone between the arid Sahara (desert) to the north and the belt of humid savannas to the south. Learn more about the Sahel here.
Water availability in the Middle East and North Africa had declined more than 75 per cent since the 1950s, the report said. It also highlighted that the aridity crisis was linked to Middle East’s more frequent and larger sand and dust storms. The research said that failure to attaincarbon...
Soil salinization limits the agricultural potential of soils in many environments and has been considered to be a significant component of desertification processes in the world's drylands. Taking the case of Africa in particular the nature of salinization processes and previous estimates of extent are...
It is a tropical grassland ( ) with equatorial and climate. Rainfall is (annual rainfall lies between mm and mm and rain mainly concentrates in summer. Savanna wetdry scanty / low Based on the map of Africa, where can we find desertification ?
it begins with an initial climate event, goes through drought, desiccation, and desertification and eventually results in the establishment of a desert; the people most susceptible to desertification inhabit regions of South and East Asia, Sub-Saharan Africa, North Africa, and the Middle East, incl...

The approach was derived from a wide range of Australian rangelands and has been tested in South Africa and USA for broad application. Recent use to assess minesite rehabilitation shows that the approach can accommodate a very wide range of function/dysfunction scenarios....
