| Abstract: | A number of very serious droughts occurred in many regions of Africa dufing the past 30 Years.It is commonly considered that they are among the most serious disasters after the Second World War in the world.The basic situations of the droughts are introduced briefly, and the main causes are analysed in detail in the paper,The lack of rainfall is one of the fators producing the droughts in Africa, but it is not the real cause of them.From the environmental viewpoints,the droughts in Africa are resulted from unsuitable land uses and managements by man,and in essence they are the results of the human environmental disturbance.Finally,the strategy for preventing droughts in Africa is suggested. |
