Increased AIDS mortality and other preexisting conditions have contributed to agricultural productivity declines in the districts of Masaka and Rakai in Uganda. These two districts were the most fertile in Uganda and also had the highest HIV seroprevalence rates in Africa. 66% of study households experienced land use decline to some extent over the past 5 years. The 11% decline in poultry production and 32% decline in cattle production was reportedly due to poor management and loss of grazing land from overpopulation and larger scale farms. The most frequently reported reasons for crop reductions were death and sickness; these was estimated as affecting 8% of families with children under 5 years in the study area. Morbidity and mortality as a reason for the decline was reported two times as much as poverty and decline in international coffee prices. Other reasons for loss of productivity were food shortages and insecurity, loss of income, and reduced ability to respond to educational and medical needs. Cassava is replacing the culturally preferred matooke banana as a crop that is more disease-, pest-, and drought resistant. The banana weevil has been a recent problem. Marginal farming systems have been the most affected by declines in land use and livestock production, but fertile areas have not been spared the impact from AIDS and adult mortality. Poverty has decreased the use of pesticides, herbicides, and fertilizers in the districts. Policy has had an impact on agricultural practices: population growth and inheritance have added to loss of individual land holdings and contributed to fallow periods and infertility. Appropriate land management practices have not been adequately promoted in the agricultural extension service. Civil wars and the drop in coffee prices have reduced the number of farm laborers. Common grazing land has been turned over to large commercial ranches. Government should maintain research and monitoring of declines in food and cash crop production and manpower needs. Policy must be designed to respond to the complicated factors affecting productivity. High AIDS prevalence areas and marginal areas where reduced production effects would be the most severe must be given priority status. Development of cash crop alternatives must be examined and perhaps supported on an experimental basis by donor agencies. Maximum productivity should be encouraged by rural extension and education agencies. A number of other specific recommendations were made for individual survival strategies to maintain high agricultural productivity.  相似文献

This paper considers input pricing rules for a producer cooperative which supplies its members with two inputs: a publicly provided private input (water), and a local public input (road services). An Israeli Moshav which allocates land equally among producers is a good example. The cooperative uses a two-part pricing rule: a product-dependent uniform fee (head tax) and a user charge per unit of the private input. Discrimination of head tax among the producer groups is shown to dominate that of user charge in the short run. However, land reallocation among producers can result in a Pareto-superior pricing rule and the Henry George theorem emerges in the long run. Thus, allowing land leasing while maintaining equal rights to land increases producer welfare.  相似文献

The relationship between migration and fertility is examined. The author proposes an alternative model to those used previously and applies it to data from the 1973 National Demographic Survey of the Philippines. The model assumes that although the fertility of migrants declines initially because of economic and psychological hardships, it rises subsequently as migrants become settled in their new environment.  相似文献

Present classifications of the developing countries are of limited usefulness as a basis for determining development policy priorities in the industrialised countries, argue our authors. They define a group of “key countries” which are of strategical importance for the world economy and outline the development risks facing these countries.1 They suggest that the OECD countries would be better advised to follow a policy of cooperation with these key countries rather than the “man mind thyself” policies which are presently gaining in popularity.  相似文献

This paper makes use of a dynamic model of an open economy with flexible exchange rates to examine the dynamic characteristics of the system for different specifications of monetary authority behavior. The model contains dynamic adjustment equations for both output and prices. Two policy rules are examined: (a) maintaining a constant nominal money supply growth, and (b) maintaining a constant nominal interest rate. With the former the system is found to be self-equilibrating. The latter, however, could easily give rise to self-perpetuating disequilibrium situations. In both cases expectations play a crucial role in the adjustment process.  相似文献

This study was undertaken to examine the influence of wife's employment on major family expenditures. Tobit analysis of data from the 1972–73 Consumer Expenditure Surveys found no relationship between wife's employment and outlays on twelve categories of expenditures. Family income had the greatest overall influence on the expenditure categories examined. Therefore, it appears that the absolute amount of income was more important than its sources in determining expenditures.  相似文献
