  2. Desert farming - Wikipedia

    en.wikipedia.org/wiki/Desert_farming

    Desert farming is the practice of developing agriculture in deserts. As agriculture depends upon irrigation and water supply, farming in arid regions where water is scarce is a challenge. However, desert farming has been practiced by humans for thousands of years. In the Negev, there is evidence to suggest agriculture as far back as 5000 BC. [1]

  3. Desert greening - Wikipedia

    en.wikipedia.org/wiki/Desert_greening

    A satellite image of the Sahara, the world's largest hot desert and third largest desert after Antarctica and the Arctic. Desert greening is the process of afforestation or revegetation of deserts for ecological restoration (biodiversity), sustainable farming and forestry, but also for reclamation of natural water systems and other ecological systems that support life.

  4. Aridisol - Wikipedia

    en.wikipedia.org/wiki/Aridisol

    Aridisols (or desert soils) are a soil order in USDA soil taxonomy. [1] Aridisols (from the Latin aridus , for "dry", and solum ) form in an arid or semi-arid climate. Aridisols dominate the deserts and xeric shrublands , which occupy about one-third of the Earth's land surface.

  5. Desertification - Wikipedia

    en.wikipedia.org/wiki/Desertification

    Desertification is a gradual process of increased soil aridity.Desertification has been defined in the text of the United Nations Convention to Combat Desertification (UNCCD) as "land degradation in arid, semi-arid and dry sub-humid regions resulting from various factors, including climatic variations and human activities."

  6. Desert ecology - Wikipedia

    en.wikipedia.org/wiki/Desert_ecology

    Desert ecology is the study of interactions between both biotic and abiotic components of desert environments. A desert ecosystem is defined by interactions between organisms, the climate in which they live, and any other non-living influences on the habitat. Deserts are arid regions that are generally associated with warm temperatures; however ...

    The land they cultivated reduced the area available to nomadic herders, causing disputes over land. The semi-arid fringes of the desert have fragile soils which are at risk of erosion when exposed, as happened in the American Dust Bowl in the 1930s. The grasses that held the soil in place were ploughed under, and a series of dry years caused ...

  8. Deserts and xeric shrublands - Wikipedia

    en.wikipedia.org/wiki/Deserts_and_xeric_shrublands

    Deserts and xeric (Ancient Greek ξηρός xērós 'dry') shrublands form the largest terrestrial biome, covering 19% of Earth's land surface area. [2] Ecoregions in this habitat type vary greatly in the amount of annual rainfall they receive, usually less than 250 millimetres (10 in) annually except in the margins.

  9. Desert riparian - Wikipedia

    en.wikipedia.org/wiki/Desert_riparian

    Desert riparian is a North American desert vegetation type (or biome) occurring in the bottoms of valleys, canyons, and other watercourses that have water at or near the surface most of the year. [1] The visual character is of large, lush, perennial green trees surrounded by dry desert vegetation and soil coloration. [ 1 ]
