Review of Short Phrases and Links

    This Review contains major "Land Degradation"- related terms, short phrases and links grouped together in the form of Encyclopedia article.

Definitions

  1. Land degradation is a composite term that describes how one or more of the complex aspects of land resources has changed for the worse over time.
  2. Land degradation is a huge problem in South Africa.
  3. Land degradation is a human induced or natural process which impairs the capacity of land to function. (Web site)
  4. Land Degradation is a universal problem and not necessarily one for the developing countries. (Web site)
  5. Land degradation is a problem of global dimensions, and it is particularly acute in dry regions.

Population

  1. High population density is not necessarily related to land degradation; it is what a population does to the land that determines the extent of degradation. (Web site)
  2. Land degradation cancels out gains advanced by improved crop yields and reduced population growth.
  3. Accelerated land degradation takes place with increasing population density and particularly under low-input systems. (Web site)
  4. Gradual shift of power together with population northwards, has been linked to the declining productivity resulting from land degradation. (Web site)
  5. As shown in Table 9, a high population density in an area that is highly vulnerable to desertification poses a very high risk for further land degradation. (Web site)

Land Degradation

  1. Table 2. Estimates of the global extent (in million km 2) of land degradation (Oldeman, 1994). (Web site)
  2. Nutrient depletion as a form of land degradation has a severe economic impact at the global scale, especially in sub-Saharan Africa. (Web site)
  3. Soils are the critical component in land degradation when it involves acidification, contamination, desertification, erosion, or salination.

Lands

  1. See also Land degradation Microorganism Slash-and-burn Soils retrogression and degradation Soil structure Surface runoff Keyline design Soil contamination .
  2. Erosion risk does not automatically imply productivity losses or land degradation, something that is often assumed. (Web site)
  3. Desertification is land degradation occurring in arid, semiarid and dry subhumid areas of the world.
  4. ESWARAN, H. and DUMANSKI, J. 1994. Land degradation and sustainable agriculture: A global perspective. (Web site)
  5. The low-input agricultural systems in the desert margins promote land degradation and desertification.

Food Security

  1. Thus, land degradation is a biophysical process driven by socioeconomic and political causes.
  2. Land degradation in drylands: current science and future prospects. (Web site)
  3. Land degradation often destroys or reduces natural beauty of landscapes. (Web site)
  4. This practical guidebook presents simple, non-technical indicators for assessing land degradation in the field.
  5. The challenge to adopt internationally acceptable procedures for the quantification of land degradation is an important one. (Web site)

Erosion

  1. Lal, R. 1990. Soil erosion and land degradation: the global risks. (Web site)

  4. There are several environmental issues in Zimbabwe including deforestation, soil erosion, land degradation, air and water pollution.

Desertification

  1. In comparison, in Table 2, Oldeman (1994), shows that the global extent of land degradation (by all processes and all ecoregions) is about 1.9 billion ha. (Web site)

  3. Eswaran and Reich (1998) attempted to evaluate vulnerability to land degradation and desertification. (Web site)

Land Quality

  1. Productivity impacts of land degradation are due to a decline in land quality on site where degradation occurs (e.g. (Web site)
  2. In the context of productivity, land degradation results from a mismatch between land quality and land use (Beinroth et al., 1994). (Web site)

Scientists

  1. Land degradation science is the domain of soil scientists. (Web site)
  2. The purpose of this ISSS Newsletter is to keep earth scientists abreast of developments in the science of land degradation. (Web site)

Task

  1. In fact, assessing the productivity effects of land degradation is a challenging task (Lal, 1998). (Web site)
  2. This is the inaugural letter of the International Task Force on Land Degradation under the auspices of the International Society of Soil Science. (Web site)

Impact
