总的来看 ,自开展绿色革命以来 ,南亚地区的粮食增长快于人口增长 ,但是 ,随着今后人口的迅速增长和粮食增产速度的降低 ,这种粮食增长快于人口增长的趋势却不可能一直保持下去。本文从可持续发展的观点出发 ,首先分析了南亚地区人口增长对粮食生产和耕地的压力 ,然后阐述了该地区粮食产量进一提高的局限性。在南亚地区 ,今后要想继续运用绿色革命技术来提高粮食产量 ,虽然有可能 ,但是却会比过去更加困难 ,而且还需要付出使生态环境受到不可弥补的破坏的代价。要使该地区人口增长同粮食生产相协调 ,关键是要控制人口增长 ,减少人口对粮食的需求量 ,同时走农业可持续发展的道路 ,节地、节水、保护环境 ,使单位土地上的粮食产量获得最大的提高。
In general, food production in South Asia has been growing faster than population growth since the Green Revolution was carried out. However, with the rapid population growth and lower rate of grain production in the future, it is impossible for such food to grow faster than the population growth trend Keep it up. From the viewpoint of sustainable development, this paper first analyzes the pressure of population growth and grain production in South Asia on the one hand, and then elaborates on the limitations of the further improvement of grain output in this region. In South Asia, continuing to use green revolutionary technologies to increase food production in the future will, though it is possible, be more difficult than in the past and will require the cost of irreparable damage to the ecological environment. The key to coordinating population growth with food production in the region is to control population growth and reduce the population’s demand for food while taking the path of sustainable agricultural development, saving land and water and protecting the environment so that land on unit land The largest increase in food production.
