Four major points emerge from this brief survey of the evidence: 1) The food crisis in 1974 seems to have been largely a result of distributional factors. The per capita availability of food grains from all sources, including imports, although below 1971 and 1972 levels, was probably above the average for 1963 to 1973. Comparison of available food supplies with estimated caloric and protein requirements of the population indicates that, on average, enough food was available to meet minimal requirements, with a small margin to spare. Supplies obtained through the government procurement and distribution program were especially short since the program depends primarily on the winter harvest, which failed badly in 1974. Thus, urban areas and some pockets of rural areas were badly hit. The poorest third of the population, who receive 20 to 30 percent less food than the national average even in normal times, were severely affected by higher prices, and there is little doubt that a sizable fraction of the population received inadequate diets. 2) The food supply for 1975 depends heavily on the winter harvest. If this is good, as it promises to be, widespread starvation, but not hunger, should be averted. Since the main shortfall was in the summer crop, the nature of the distribution problem will be different and shortages may be spread more evenly over the population. Nevertheless, the situation seems to forebode considerable hardship for the poorer segments of the population. 3) Food requirements will continue to grow over the foreseeable future as a result of rising population and incomes. India's agricultural resources are still relatively poorly exploited. In the short run, output can probably be increased substantially by increased fertilizer use on traditional as well as new varieties. In the longer run, increased production can be obtained from more intensive cropping, expansion of surface and groundwater irrigation, improved water management, and improved cultural practices brought about by more active agricultural research and appropriate land and pricing policies. These measures will need buttressing by an expanded food storage program if extreme hardships due to periodic drought are to be avoided. 4) India's farmers have shown considerable willingness to innovate under favorable conditions. The rate of adoption of HYV's in the first few years after their introduction was impressive. The same was true for tubewells and fertilizers. Nevertheless, many of the easy gains may already have been made. Fragmentary information on the quality of irrigation indicates that the acreage sown to wheat and rice HYV's may be approaching an upper limit in many areas because of the requirements of these varieties for a high degree of water control. Further gains will require more aggressive and coordinated policies for agricultural development. A major change in development strategy may be required if scarcities and hardships such as those currently being experienced are to be avoided in the future, and some hard political decisions on land reform and consolidation may have to be made. It is to be hoped that bold and imaginative agricultural policies will be followed, and that they will be accompanied by greater efforts to reduce population growth to manageable levels.
1)1974年的粮食危机似乎主要是分配因素造成的。包括进口在内的所有来源的人均粮食供应量,虽然低于1971年和1972年的水平,但可能高于1963年至1973年的平均水平。将现有的粮食供应与估计的人口热量和蛋白质需求进行比较表明,平均而言,有足够的粮食来满足最低需求,并有少量盈余。通过政府采购和分配计划获得的供应尤其短缺,因为该计划主要依赖冬季收成,而1974年冬季收成严重歉收。因此,城市地区和一些农村地区受到了严重冲击。最贫困的三分之一人口,即使在正常时期获得的食物也比全国平均水平少20%至30%,受到价格上涨的严重影响,毫无疑问,相当一部分人口的饮食不足。2)1975年的粮食供应在很大程度上取决于冬季收成。如果冬季收成如预期的那样好,大范围的饥饿,但不是饥荒,应该可以避免。由于主要短缺在于夏季作物,分配问题的性质将有所不同短缺可能会更均匀地分布在人口中。然而,这种情况似乎预示着较贫困人群将面临相当大的困难。3)由于人口和收入的增加,在可预见的未来粮食需求将继续增长。印度的农业资源仍未得到充分利用。短期内,通过增加对传统品种和新品种的化肥使用,产量可能会大幅提高。从长远来看,通过更集约的种植、扩大地表水和地下水灌溉、改善水资源管理以及通过更积极的农业研究和适当的土地及定价政策带来的更好的种植方式,可以实现产量的增加。如果要避免因周期性干旱而导致的极端困难,这些措施将需要通过扩大粮食储存计划来加强。4)印度农民在有利条件下表现出了相当大的创新意愿。高产品种在引入后的头几年的采用率令人印象深刻。管井和化肥的情况也是如此。然而,许多容易获得的成果可能已经取得。关于灌溉质量的零散信息表明,由于这些品种对高度水控制的要求,许多地区小麦和水稻高产品种的播种面积可能接近上限。进一步的增产将需要更积极和协调的农业发展政策。如果要避免未来出现目前正在经历的短缺和困难,可能需要对发展战略进行重大改变,并且可能不得不就土地改革和合并做出一些艰难的政治决策。希望能够采取大胆而富有想象力的农业政策,并辅之以更大的努力将人口增长降低到可控制的水平。
