  2. 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.

  3. Special Report on Climate Change and Land - Wikipedia

    The United Nations' Intergovernmental Panel on Climate Change's (IPCC) Special Report on Climate Change and Land (SRCCL), also known as the "Special Report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems", [1] [2] is a landmark study from 2019 by 107 experts from 52 countries.

  4. Economics of Land Degradation Initiative - Wikipedia

    en.wikipedia.org/wiki/Economics_of_Land...

    Soil on degraded land is less resilient and crops grown on degraded soil produce lower yields. Land degradation also negatively influences global food security: in the next 25 years, global food production might drop by up to 12%. [8] This will lead to an increase in average food prices of up to 30%. [9]

  5. Soil retrogression and degradation - Wikipedia

    en.wikipedia.org/wiki/Soil_retrogression_and...

    Globally, the annual loss of 76 billion tons of soil costs the world about US$400 billion per year. In Canada, on-farm effects of land degradation were estimated to range from US$700 to US$915 million in 1984. The economic impact of land degradation is extremely severe in densely populated South Asia, and sub-Saharan Africa. [8]

  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. Land surface effects on climate - Wikipedia

    en.wikipedia.org/wiki/Land_surface_effects_on...

    Land surface effects on climate are wide-ranging and vary by region. Deforestation and exploitation of natural landscapes play a significant role. Some of these environmental changes are similar to those caused by the effects of global warming .

  8. UN Decade on Ecosystem Restoration - Wikipedia

    en.wikipedia.org/wiki/UN_Decade_on_Ecosystem...

    Degradation of land and marine ecosystems adds to the threat of mass species extinction, and has a negative impact on the well-being of some 3.2 billion people, costing around 10% of the annual global gross domestic product (c. $6.3 trillion) in loss of species and ecosystem services. [20]

  9. Land use - Wikipedia

    en.wikipedia.org/wiki/Land_use

    [3] [4] Effects of land use choices and changes by humans include for example urban sprawl, soil erosion, soil degradation, land degradation and desertification. [5] Land use and land management practices have a major impact on natural resources including water, soil, nutrients, plants and animals. [6] [7]
