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 ...
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 world's largest non-polar deserts. Deserts occupy about one third of Earth's land surface. [6] Bottomlands may be salt -covered flats. Eolian processes are major factors in shaping desert landscapes. Polar deserts (also seen as "cold deserts") have similar features, except the main form of precipitation is snow rather than rain.
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 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.

The Sahara (/ s ə ˈ h ɑːr ə /, / s ə ˈ h ær ə /) is a desert spanning across North Africa.With an area of 9,200,000 square kilometres (3,600,000 sq mi), it is the largest hot desert in the world and the third-largest desert overall, smaller only than the deserts of Antarctica and the northern Arctic.
Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades. This may sound like a small uptick, but the implications are profound. Rising temperatures will destroy plant and animal habitats ...
Deserts and xeric shrublands are a biome defined by the World Wide Fund for Nature. [1] 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 ...
