    en.wikipedia.org/wiki/Soil_contamination

    Soil contamination, soil pollution, or land pollution as a part of land degradation is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste .

  3. Land degradation - Wikipedia

    en.wikipedia.org/wiki/Land_degradation

    Overgrazing by livestock can lead to land degradation. Land degradation is a process where land becomes less healthy and productive due to a combination of human activities or natural conditions. The causes for land degradation are numerous and complex. [1] Human activities are often the main cause, such as unsustainable land management practices.

    In total, one-third of the world's population lives in drylands where land degradation is reducing food supplies, biodiversity, water quality and soil fertility. [ 2 ] The bioreclamation of degraded lands (BDL) system was developed by the International Crops Research Institute for the Semi-Arid Tropics ( ICRISAT ), with the aim of helping ...

    This reduces the food security, which many countries facing soil degradation already do not have. [8] Slight degradation refers to land where yield potential has been reduced by 10%, moderate degradation refers to a yield decrease of 10–50%. Severely degraded soils have lost more than 50% of their potential.

  6. Environmental degradation - Wikipedia

    en.wikipedia.org/wiki/Environmental_degradation

    According to Global Assessment of Land Degradation and Improvement (GLADA) a quarter of land area around the globe can now be marked as degraded. Land degradation is supposed to influence lives of 1.5 billion people and 15 billion tons of fertile soil is lost every year due to anthropogenic activities and climate change. [29]

  7. Soil erosion - Wikipedia

    en.wikipedia.org/wiki/Soil_erosion

    Wind erosion is a major geomorphological force, especially in arid and semi-arid regions. It is also a major source of land degradation, evaporation, desertification, harmful airborne dust, and crop damage—especially after being increased far above natural rates by human activities such as deforestation, urbanization, and agriculture. [22] [23]

  8. Soil conservation - Wikipedia

    en.wikipedia.org/wiki/Soil_conservation

    Soil conservation is the prevention of loss of the topmost layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination. Slash-and-burn and other unsustainable methods of subsistence farming are practiced in some lesser developed areas.

  9. Grassland degradation - Wikipedia

    en.wikipedia.org/wiki/Grassland_Degradation

    Grassland in Europe. Grassland degradation, also called vegetation or steppe degradation, is a biotic disturbance in which grass struggles to grow or can no longer exist on a piece of land due to causes such as overgrazing, burrowing of small mammals, and climate change. [1]
