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."
Like arid deserts, temperatures can vary greatly in semi deserts. They share some characteristics of a true desert and are usually located at the edge of deserts and continental dry areas. They usually receive precipitation from 250 to 500 mm (9.8 to 19.7 in) but this can vary due to evapotranspiration and soil nutrition.
Desertification is the process by which a piece of land becomes a desert, as the word desert implies. [3] The loss or destruction of the biological potential of the land is referred to as desertification. [4] It reduces or eliminates the potential for plant and animal production on the land and is a component of the widespread ecosystem ...
This is a list of deserts sorted by the region of the world in which the desert is located. Africa. Namib Desert.
The Gobi Desert, Ömnögovi Province. Desertification is a key issue in Mongolia. There are many pressing environmental issues in Mongolia that are detrimental to both human and environmental wellness. These problems have arisen in part due to natural factors, but increasingly because of human actions.
The desert climate or arid climate (in the Köppen climate classification BWh and BWk) is a dry climate sub-type in which there is a severe excess of evaporation over precipitation. The typically bald, rocky, or sandy surfaces in desert climates are dry and hold little moisture, quickly evaporating the already little rainfall they receive.
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 ]
Certain desert endotherms have evolved very specific and unique characteristics to combat dehydration. Male sandgrouse have specialized belly feathers that are able to trap and carry water. This allows the sandgrouse to provide a source of hydration for their chicks, who do not yet have the ability to fly to water sources themselves. [14]
