Poverty,population and environmental degradation in China   总被引:7,自引:0,他引:7  
Rozelle S  Huang J  Zhang L 《Food Policy》1997,22(3):229-251
This article examines the relationship between poverty, population, and environmental degradation in China. Environmental conditions include water pollution, deforestation, destruction of grasslands, soil erosion, and salinization. The authors review China's success in controlling environmental degradation through leadership, environmental policies, and institutional capacity. Findings suggest that environmental progress is best achieved indirectly by poverty alleviation, market integration, and population control. Government policies were not very effective. Degradation occurs due to limited financial resources, poorly trained personnel, and political factors. Control of water pollution was instituted since the 1980s. The levels of pollutants have been reduced, but the type of pollutant determines the seriousness of impact. Water pollution is due to industrial wastes, agricultural run-off, and soil erosion. Since the 1970s, reforestation targets have not been met. Technical extension and monitoring of planting is not available in most areas, and private, profit seeking interests control acreage. Grassland destruction is due to deforestation, agricultural expansion, and overgrazing. Independent regional authorities have successfully managed pasture programs. Erosion is the most serious in Loess Plateau, the Red Soils area, the Northeast China Plain, and the Northwest Grasslands, which comprise 70% of total land area. In 1990, erosion control was practiced in 39% of eroded land area. Salinization has remained fairly constant. Environmental controls (direct regulation, planned recovery, and state-mandated technological improvements) are uneven. The main tool for environmental management is the State Environmental Protection Commission and its executive unit, SEPA. Problems stem from vague laws, lack of means of enforcement, lack of coordination of laws, and lack of standards, schedules, and other provisions in ordinances.  相似文献

The limited successes achieved with development in the Third World and the national states in Southern Africa have necessitated a considerable change in development thinking and practice. The conventional developmental approach, which is based on growth models, is inappropriate for the conditions in the LDCs. A new development approach, coupled with an appropriate development strategy, has culminated in the development literature.

In this article the poverty problem in Southern Africa is outlined as a general background, whereafter the new development approach and a few guidelines for an appropriate development strategy is discussed. The application of the new strategy in the circumstances of Southern Africa is highlighted.  相似文献

I have argued that for the period from 1661 to 1850, patent data in England were consistent in that no official changes in methods and standards of issuance occurred. Book data on titles published on farming production methods were similarly consistent from 1523 to the mid-19th century because the market for books developed gradually and the technology of printing was not substantially changed until the mid-19th century.My main point is that data on output of titles of books on farming productive techniques in England are useful measures of technological change. Books did have information on good production methods and could express productive ideas where a patent may not be issued. Further, the literacy rate of farmers was high so that books were likely an important source of ideas on farming production methods. Finally, the fluctuations in the book data were highly related to the fluctuations in the patent data, suggesting that a common set of factors caused those fluctuations. The high correlations between the detrended book and patent data indicate that if we accept patenting as a useful measure of technology we may also accept book title output of a technical nature as a good measure of technical change.I used the data for a simple analysis of the trend growth rate of agricultural technology in England from 1551 to 1850. While there is limited evidence to show that the subperiod 1651–1750 saw a slowing in the trend of development of farming technology, I argue that a division of the entire period into subperiods is too simplistic. A more fruitful approach would be an analysis of the underlying forces that determined the trend of development of the technology of English agriculture.The next step is an analysis of the forces that influenced technological development of English farming. From an economic point of view, market forces play an important role in influencing technology. Because such an analysis deserves careful consideration, I leave that to another paper (see Sullivan and Simon, 1983).  相似文献
