Tbe causes of the food crisis in Africa are three-fold. First, Africa is experienciDg a higher rate of population growth than any other conlinent' Food produclion must increase by at least 3 per cene annually sinply to naintain Ehe quanEity of food avail-able per person, and that. does not take into consideration the need to irnprove nutrilional standards. However, an increase ir food producEion by nore tban 3 per cent annually over an extended period of time has only been possibte in a few coungries, and generally reouires najor increases in the use of fertilizer, capital eouipment. irrigation and the introduction of appropriate nert seeds and technologies. 329. Second, Africa nay be underqoing clinatic changes and soi!- erosion on a scale lhat is perhaps not yet fully apPreciated. Forests are being cut for fuel and lunber at a devastating rate. For exanple' 80 per cent of the Ganbia was covered by forest in 1920r this was dol.'n to 40 per cent in 1965, and f0 per cent today' Deforestation has resulted in widespread soil erosion and changes in general clirnatic and rain patterns. Specifically, as forests are cut down, water runoff increases, which reduces noisture in the air and the fornation of cfouds, leading to less rain and resulting in topsoil tbat is dry and easily blown away.
