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.
The small desert nation reuses 86% of its wastewater as of 2011, and 40% of the total water used by agriculture was reclaimed wastewater. [10] Desalination, brackish, or effluent water also accounts for 44% of Israel's water supply, [11] and the world's largest seawater desalination plant is the Sorek Desalination Plant located in Tel Aviv.

Greening the Desert II site, Dead Sea Valley Jordan (photographed 2018) is an oasification project In hydrology , oasification is the antonym to desertification by soil erosion . This technique has limited application and is normally considered for much smaller areas than those threatened by desertification.
The Sahel region (brown), proposed Great Green Wall (green), and participating countries (white) Satellite photo of the Sahara The Great Green Wall or Great Green Wall for the Sahara and the Sahel (French: Grande Muraille Verte pour le Sahara et le Sahel; Arabic: السور الأخضر العظيم, romanized: as-Sūr al-ʾAkhḍar al-ʿAẓīm) is a project adopted by the African Union in ...
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."
It has been shown that while some native desert plant species have seeds with self-burial mechanisms that can establish readily in crusted areas, many exotic invasive plants do not. Therefore, the presence of biological soil crusts may slow the establishment of invasive plant species such as cheatgrass (Bromus tectorum). [21]
Sand dunes in the Sahara Desert. 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.
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.
