Net farm income for most representative farms in 2008 will be higher than in 1999. However, low profit farms, which consist of 25% of the farms in the study, may have a negative net farm income throughout the forecasting period and may not have financial resiliency to survive. This is true under both optimistic and pessimistic scenarios. All farms except low profit farms may do well under the optimistic scenario, while only high profit farms may be able to survive under the pessimistic scenario. Cropland prices are projected to remain constant.

There is considerable interest in the determination of farmland values. Although alternative models exist, present value models have played a central role in recent studies of agricultural land markets. Alston (1986) uses a present value model to examine the effects of inflation and real growth in net rental income on farmland prices (see also Melichar, 1979).

In rural areas of Bangladesh, poverty is pervasive and associated with high rates of malnutrition especially among preschool children and women. Apart from low levels of energy intakes, it is increasingly recognized that rice-dominated diets such as those consumed by most poor in the countryside may not supply all micronutrients required for a healthy life and productive activities. Children and women are particularly vulnerable to these micronutrient deficiencies as they face relatively higher requirements for growth and reproduction.

The patchwork of government influences that shape the protection and management of construction mineral resources--sand, gravel, and crushed stone--includes statutes, regulations, guidance documents, and court decisions at the federal, state, and local level. Across the Washington-Baltimore metropolitan area, both these influences and the experiences that the counties have had in managing construction mineral resources range widely.

una amenaza para la seguridad alimentaria de los países en desarrollo en el año 2020?
Documents de politique et mémoiresdécembre, 1999Asie, Asie central, AfghanistanGlobal population in the year 2020 will be a third higher than in 1995, but demand for food and fiber will rise by an even higher proportion, as incomes grow, diets diversify, and urbanization accelerates. However this demand is met, population and farming pressure on land resources will intensify greatly. There is growing concern in some quarters that a decline in long-term soil productivity is already seriously limiting food production in the developing world, and that the problem is getting worse. Sarah Sherr first focuses on the magnitude and effects of soil degradation.
