Desert greening. 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. The term "desert greening" is intended to apply to both cold and hot arid and ...
Desertification is a type of gradual land degradation of fertile land into arid desert due to a combination of natural processes and human activities. The immediate cause of desertification is the loss of most vegetation. This is driven by a number of factors, alone or in combination, such as drought, climatic shifts, tillage for agriculture ...
Land restoration, which may include renaturalisation or rewilding, is the process of restoring land to a different or previous state with an intended purpose. That purpose can be a variety of things such as what follows: being safe for humans, plants, and animals; stabilizing ecological communities; cleaning up pollution; creating novel ecosystems; or restoring the land to a historical ...
Disturbing the delicate desert crust, a thin layer of bacteria-rich soil that retains water and nutrients and slows erosion, can contribute to powerful dust storms that release particles into the air.
Soil conservation. Contour plowing in Pennsylvania in 1938. The rows formed slow surface water run-off during rainstorms to prevent soil erosion and allow the water time to infiltrate into the soil. 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 ...
Environmental issues in Yemen. Environmental issues in Yemen are abundant and are divided into the categories of land and water. In the aspect of water, Yemen has limited natural fresh water resources and inadequate supplies of potable water. As for the land, two main issues of Yemen are overgrazing and desertification.
Reforestation was conducted as a part of afforestation due to inabilities of self-recovering by the natural land itself due to serious soil pollution and loss of woods consequence in loss of soils for plants to grow, thus needing artificial efforts involving introducing of healthy soils from outside. Starting from around 1897, about 50% of once ...
Valdivian temperate rainforest in the Oncol Park. Environmental issues in Chile include deforestation, water scarcity, pollution, soil erosion, climate change, and biodiversity loss, especially in its industry-heavy "sacrifice zones". [ 1][ 2] The country of Chile is a virtual continental island that spans over (2,600 miles) 4,200 kilometers.
