    Agriculture is vital to the economies of Sub-Saharan Africa: two-thirds of the region’s people depend on it for their livelihoods. Nevertheless, agricultural productivity in most of the region is stagnant or declining, in large part because of land degradation. Soil erosion and soil nutrient depletion degraded almost 70 percent of the region’s land between 1945 and 1990; 20 percent of total agricultural land has been severely degraded. If left unchecked, land degradation could seriously threaten the progress of economic growth and poverty reduction in Africa.

    a threat to developing-country food security by 2020?

    Publicación revisada por pares

    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.

    The costs of doing nothing about land degradation are several times higher than the costs of taking action to reverse it. Despite the crucial role land plays in human welfare and development, investments in sustainable land management are low, especially in developing countries. These findings come from the book, Economics of Land Degradation and Improvement—A Global Assessment for Sustainable Development, which examines the costs of land degradation and what needs to be done to reverse it.

    Many opportunities exist for mitigating greenhouse gas (GHG) emissions through better management of trees and soils. There is potential for both direct mitigation through better management of carbon in agricultural landscapes and indirect mitigation through reduced pressure on carbon stored in forests, peatlands, and wetlands. Effectively harnessing these opportunities will take bold action in climate change negotiations.

    In recent years, prices of agricultural land have increased quickly, actually doubling and tripling in many parts of the world. This land value reassessment has been prompted by rising crop prices and perceived land scarcity. But even as the value of land rises, land degradation continues and investments to prevent it are lagging. Awareness of environmental risks has moved to the forefront of global consciousness during the past 25 years.

    By the year 2020 land degradation may pose a serious threat to food production and rural livelihoods, particularly in poor and densely populated areas of the developing world. Appropriate policies are required to encourage land-improving investments and better land management if developing countries are to sustainably meet the food needs of their populations.
