Deserts And Desertification Brief introduction to desertification, including causes and effects. http://www.didyouknow.cd/deserts.htm
Extractions: Did you know? More than 70% of earth's dryland is affected by desertification About 3,6 billion of the world's 5.2 billion hectares of useful dryland for agriculture has suffered erosion and soil degradation. In more than 100 countries, 1 billion of the 6 billion world population is affected by desertification, forcing people to leave their farms for jobs in the cities. Desertification takes place in dryland areas where the earth is especially fragile, where rainfall is nil and the climate harsh. The result is the destruction of topsoil followed by loss of the land's ability to sustain crops, livestock or human activity. The economic impact is horrendous, with a loss of more than $40 billion per year in agricultural goods and an increase in agricultural prices. Climatic changes can trigger the desertification process, but human activities frequently are the proximate cause. Overcultivation exhausts the soil. Deforestation removes trees that hold the soil to the land. Overgrazing of livestock strips the land of grasses. According to a UN study, about 30% of earth's land - including the 70% of dryland - is affected by drought. Every day, about 33,000 people starve to death.

Desertification This degradation of formerly productive land desertificationis a complex process. desertification does not occur in linear, easily mappable patterns. http://pubs.usgs.gov/gip/deserts/desertification/
Extractions: The Sahelian drought that began in 1968 was responsible for the deaths of between 100,000 and 250,000 people, the disruption of millions of lives, and the collapse of the agricultural bases of five countries (photograph by Daniel Stiles, UNEP). The world's great deserts were formed by natural processes interacting over long intervals of time. During most of these times, deserts have grown and shrunk independent of human activities. Paleodeserts, large sand seas now inactive because they are stabilized by vegetation, extend well beyond the present margins of core deserts, such as the Sahara. In some regions, deserts are separated sharply from surrounding, less arid areas by mountains and other contrasting landforms that reflect basic structural differences in the regional geology. In other areas, desert fringes form a gradual transition from a dry to a more humid environment, making it more difficult to define the desert border. These transition zones have very fragile, delicately balanced ecosystems. Desert fringes often are a mosaic of microclimates. Small hollows support vegetation that picks up heat from the hot winds and protects the land from the prevailing winds. After rainfall the vegetated areas are distinctly cooler than the surroundings. In these marginal areas, human activity may stress the ecosystem beyond its tolerance limit, resulting in degradation of the land. By pounding the soil with their hooves, livestock compact the substrate, increase the proportion of fine material, and reduce the percolation rate of the soil, thus encouraging erosion by wind and water. Grazing and the collection of firewood reduces or eliminates plants that help to bind the soil.
Desertification Information Network Of China About studies of the phenomenon and efforts to combat it, including uses of traditional knowledge. Includes research publications, photos, and links. http://www.din.net.cn/
Extractions: Desertification is one of the major environmental issues in the world today. At present, two third of the countries and districts in the world, one fourth of the global land territory and nearly 100 million world population are threatened by desertification. China is one of the countries with serious disasters of desertification in the world. According to the monitoring results of China's State Forestry Administration in 1999, the desert areas are still expanding in China with an average increase of about 10,400 square kilometers per year, and China has 2.67 million square kilometers of desert land, accounting for 27.9 percent of China's total territory, The UN Convention to Combat Desertification (CCD) was opened for signing in Oct. 1994 in Paris and Chinese Delegation has signed the CCD on behalf of the Government of China. On December 30th 1996, the Outstanding Committee of the People's Congress has ratified the CCD and China has become officially the member state of the parties of CCD.
IMPACTS - Desertification Climate Change and the Mediterranean Region. Executive Summary. Water shortages and poor harvests during the droughts of the early 1990s exposed the acute vulnerability of the Mediterranean region to http://www.greenpeace.org/~climate/science/reports/desertification.html
Extractions: climate science Climate Change and the Mediterranean Region Executive Summary Water shortages and poor harvests during the droughts of the early 1990s exposed the acute vulnerability of the Mediterranean region to climatic extremes. Against this backdrop, the prospect of a major climate change brought about by human activities is a source of growing concern, raising serious questions over the sustainability of the region. This report examines the potential implications of global climate change for the Mediterranean region. Drawing on the results of recent studies, it reviews possible changes in climate together with recent trends, the potential impacts of climate change and the implications for sustainable development. One key finding is that future climate change could critically undermine efforts for sustainable development in the Mediterranean region. In particular, climate change may add to existing problems of desertification, water scarcity and food production, while also introducing new threats to human health, ecosystems and national economies of countries. The most serious impacts are likely to be felt in North African and eastern Mediterranean countries. The report concludes that while there is some scope for adaptation, ensuring the long-term sustainability of the region requires urgent action to cut global emissions of greenhouse gases.

Land Use -- Land Degradation And Desertification CIESIN Thematic Guides *DRAFT* Land Degradation and desertification. Land degradation has been defined as a reduction in the soil's capacity to produce in terms of quantity, quality, goods, and services. desertification is generally viewed as an advanced stage of land degradation the United Nations Conference on desertification (UNCOD), desertification was defined as a "diminution http://www.ciesin.org/TG/LU/degrad.html
Extractions: CIESIN Thematic Guides *DRAFT* Land degradation has been defined as a reduction in the soil's capacity to produce in terms of quantity, quality, goods, and services. Several other concepts are important to this definition: Landscapes throughout the world undergo transformation processes that include some form of natural degradation, but these processes are usually compensated for and counterbalanced by nature's inherent recovery ability. Net degradation occurs whenever the degradation processes significantly exceed nature's restorative capacity. Blaikie and Brookfield (1987) present a comprehensive introduction to and definition of the nature of land degradation in Land Degradation and Society . They describe degradation as a natural process that can be enhanced or dampened by human intervention. Chisholm and Dumsday (1987) also discuss society's role in degrading land in Land Degradation Desertification is generally viewed as an advanced stage of land degradation.
