This paper emphasizes the benefits of an agricultural strategy of development in developing countries. It begins by analyzing the close links between food and employment in the development process. In an underdeveloped country, food production is minimal, but demand is as well because of the small population growth. After development begins, income rises and food demand outstrips production. Only at later stages of development can food production meet demand. The middle stage of development describes most developing countries, which have averaged annual growth rates of 3% per capita in 1966-80. The growth in food demand must be met through technological advance in agriculture: high-yield seeds, fertilizers, and irrigation, which, for example, helped India increase cereal yields 29% between 1954-55 and 1964-65. The rate of growth in cropped areas has declined between 1961-1980, making increased yields more necessary. Growth in employment and income leads to higher food demand, which leads to higher prices and labor costs and a tendency towards capital-intensive agriculture. As the rural sector becomes wealthier, there is also more opportunity for non-agricultural rural workers, creating still more demand. In the final development stage, agricultural products can generate foreign exchange. In Asia, the priority is to ensure efficient outcomes of capital allocations, while in Africa, technology must be instituted. Public investment has been shown to be essential to rapid development in Japan, Taiwan, and the Punjab of India. The absence of this investment in Africa, partly because of an overemphasis on urban sector investment, is largely responsible for the backward state of African agriculture. Often rural areas are overtaxed, agricultural experts are lacking, and there is a growing presence of urban bureaucrats. Both experts in the donor community and farmers themselves must become more vocal in demanding investment in the agricultural sector. 相似文献

An important human welfare implication of climate involves effects of interannual variation in temperature and precipitation on agriculture. Year-to-year variations in U.S. climate result from El Niño-Southern Oscillation (ENSO), a quasi-periodic redistribution of heat and momentum in the tropical Pacific Ocean. The study described here represents a preliminary assessment of the value to the entire U.S. agricultural sector of improved ENSO forecasts in the southeastern United States. This interdisciplinary assessment combines data and models from meteorology, plant sciences, and economics under a value of information framework based on Bayesian decision theory. An economic model of the U.S. agricultural sector uses changes in yields for various ENSO phases to translate physical (yield) effects of ENSO changes into economic effects on producers and on domestic and foreign consumers. The value of perfect information to agriculture is approximately $145 million. The economic value of an imperfect forecast is $96 million. These results suggest that increases in forecast accuracy have substantial economic value to agriculture. 相似文献

This study evaluates the changes which have occurred in rural Egypt since 1952 in terms of a growth-conscious, poverty-oriented definition of development. According to the study, development requires improvements in three criteria over time: poverty, inequality and productivity (land and labor). Using a variety of empirical data, the study demonstrates that each of these criteria has either stabilized or improved in rural Egypt since 1952. The study therefore concludes that ’development’ has indeed taken place in the Egyptian countryside. However, the low rate of qualitative structural change in the basic factors of production (land and labor) raises questions about the prospects for such development in the future. 相似文献
