自70年代全球出现粮食大欠收以来,80年代中期情况稍许转好,但世界粮食形势依然是十分严峻的。事实之一:饥民多达数亿。据有关方面估计,截至80年代中期,全世界处于营养不良和饥饿状态的人口约为8亿。也就是说世界人口每五人中就有一人在挨饿。曾经属于粮食净输出地区的拉丁美洲如今每七人中就有一人营养不良。被联合国列为最不发达国家的一些非洲国家,处于饥懂状态的人口占到总人口的25-30％。亚洲的一些最不发达国家也是如此。事实之二:一些国家粮食产量增长赶不上人口增长。50年代以来,许多国家逐渐重视农业特别是粮食的生产,使粮食增长超过人口增长的速度。例如,
Since the serious food default in the world in the 1970s, the situation in the mid-1980s has been slightly better, but the world food situation remains very serious. One of the facts: hundreds of millions of hungry people. According to estimates, by the mid-1980s, the number of undernourished and hungry people in the world was about 800 million. This means that one out of every five people in the world’s population is starving. Latin America, once a net food exporter, is now malnourished by one out of seven people. Some African countries, which are listed as the least developed countries by the United Nations, account for 25-30% of the total population. The same is true for some of the least developed countries in Asia. Fact number two: In some countries, the increase in grain output can not keep up with population growth. Since the 1950s, many countries have gradually begun to attach importance to the production of agriculture, especially grain, so that the grain growth will exceed the population growth rate. E.g,
