Topic: Land degradation

  UNDP/GEF
Often, land degradation weakens the ability of communities to depend on their environment for their livelihoods.
Activities that contribute to land degradation include: soil erosion, denudation, pollution, loss of organic matter, fertility and vegetation cover, invasive species, habitat conversion (whether urban or agricultural) and aquifer degradation.
The Multifocal OP has a land degradation component, and the Sustainable Land Management OP is the newest one arising out of the GEF Assembly's approval of this focal area.

 Land Degradation: An overview | NRCS Soils
Land degradation can be considered in terms of the loss of actual or potential productivity or utility as a result of natural or anthropic factors; it is the decline in land quality or reduction in its productivity.
Land degradation and economic growth or lack of it (poverty) are intractably linked; (people living in the lower part of the poverty spiral are in a weak position to provide the stewardship necessary to sustain the resource base.
Land use must match land quality; appropriate national policies should be implemented to ensure this occurs to reduce land degradation; (a framework for evaluation of sustainable land management [Dumanski et al., 1992] is a powerful tool to assess such discrepancies and assure sustainability).

 LEAD digital library: Livestock’s long shadow - Environmental issues and options
Land degradation can be limited and reversed through soil conservation methods, silvopastoralism, better management of grazing systems, limits to uncontrolled burning by pastoralists and controlled exclusion from sensitive areas.
Global figures are not available but in the United States, with the world’s fourth largest land area, livestock are responsible for an estimated 55 percent of erosion and sediment, 37 percent of pesticide use, 50 percent of antibiotic use, and a third of the loads of nitrogen and phosphorus into freshwater resources.
Indeed, the livestock sector may well be the leading player in the reduction of biodiversity, since it is the major driver of deforestation, as well as one of the leading drivers of land degradation, pollution, climate change, overfishing, sedimentation of coastal areas and facilitation of invasions by alien species.

 Focal Areas - GEF
GEF projects to reverse the degradation of international waters are informed by-and help to realize the objectives of-a mosaic of regional and international water agreements.
Destroyed forests and degraded water resources imperil biodiversity, induce climate change, and disturb hydrologic cycles.
In October 2002, the GEF Assembly approved land degradation as a new focal area, which means that a project may tackle land degradation as its primary objective.

 IGU
The main theme of the symposium is land degradation and land use change in a dynamic environment.
Land degradation in response to land cover and land use change are critical issues through out the world.
The symposium will be held in Taiwan and Japan, a particularly appropriate venue since these countries lie in a region that is regularly subject to the threat of earthquakes and typhoons and characterised by high population density, so that the problems of landuse and land degradation are especially prevalent and dynamic.
