HIV/AIDS has severely affected many of the countries in sub-Saharan Africa, particularly in Southern and Eastern Africa where the epidemic is now concentrated. The United Nations and WHO are pursuing ambitious programmes of both HIV prevention and AIDS treatment To date there has been little examination of the impact of these programmes in the middle or longer tern (five to 25 years). This study has projected national populations under different scenarios of HIV prevalence, prevention and treatment for 2005-2030 for Botswana, Malawi and Tanzania. The population data is used to examine medical staff requirements, treatment costs and associated changes in food requirements. The projections demonstrate the need for effective prevention programmes in conceit with treatment Serious shortages of medical staff and inadequate financial resources are identified as bottlenecks to effective implementation of treatment in two of the three countries.

This publication discusses the general food requirements of honey bees, Apis mellifera L., and presents formulas for supplementary diets and methods for feeding such foods to bee colonies. In early spring, before pollen and nectar are available or at other times of the year when these materials are not available for bees in the field or in the hive, supplementary feeding may help the colony survive or sustain brood rearing and colony development. None of the protein supplemental foods fed to honey bees is a complete replacement for natural pollen; however, several brewer's yeast products, Wheast, and soybean flour, fed singly or in combination, can be used to improve the nutrition of colonies when natural pollen is scarce. Cane or beet sugar and isomerized corn sirup can be used to supplement the bees' diet of nectar or honey.

Industrialization and urbanization In South Korea have led to higher wages, thus Increasing the quantity and quality of food demanded. Population growth and rising per capita food demand have resulted in declining self-sufficiency in agricultural commodities. Imports, especially rice, will rise substantially to meet the domestic need. Further demand for all food is estimated to rise from $1.4 billion in 1964 to $2.2 billion in 1971, with an average growth rate of 6.5 percent per year., This report summarizes the major findings of the comprehensive study, of An Analysis of Food Consumption in the Republic of Korea, prepared under contract for the U.S. Department of Agriculture by a team of economists at the Yonsei University, Seoul, Korea, in 1969, under the direction of Doctors Ki Hyuk Pak and Kee Chun Han. The main objectives of the study were to obtain an accurate assessment of food consumption by select food groups as well as by individual food Items, and to develop reliable indications of future needs. Findings in this study are those of the contractor and do not necessarily coincide with views of the Department.

Agricultural production in El Salvador has been increasing, but at a rate slower than population. The principal export crops--coffee, cotton, and sugar--have benefited most from improved technology and from attention to marketing by cooperative organizations. Increased corn production has resulted from many years of research and extension work with local farmers. Wheat is the country's chief agricultural import. El Salvador is an important source of coffee beans and sugar for the United States, which in turn is El Salvador's prime source for wheat. Western Europe, Japan, and the Central American Common Market are important trading partners of El Salvador.
