    Soil erosion is one of the most serious environmental problems in Ethiopia. Coupled with growing populations, falling per capita food production and worsening poverty, loss of productive land due to land degradation undermines rural livelihoods and national food security. Despite their awareness of the erosion problem, peasants' investments in land have been limited. We use an applied nonseparable model to simulate conservation decisions. Pervasive market imperfections, poverty and high rates of time preference seem to undermine erosion-control investments.

    Global 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.
