Drylands cover 41.3% of the Earth's land surface, including 15% of Latin America, 66% of Africa, 40% of Asia, and 24% of Europe. There is a significantly greater proportion of drylands in developing countries (72%), and the proportion increases with aridity : almost 100% of all hyper-arid lands are in the developing world.
The biggest dry land area below sea level that has been known to exist during the geological past, as measured by continuous volume of atmospheric air below sea level, was the dry bed of the Mediterranean Sea of the late Miocene period during the Messinian salinity crisis.
Generally speaking, only a few regions of the dry-land part of the Earth are so remote or have such a harsh climate that no one uses those areas for even part of the year. These places are tiny islands, the driest part of large deserts, very high mountains, and ice caps.
Dryland farming and dry farming encompass specific agricultural techniques for the non-irrigated cultivation of crops. Dryland farming is associated with drylands , areas characterized by a cool wet season (which charges the soil with virtually all the moisture that the crops will receive prior to harvest) followed by a warm dry season.
Dry lake – Area that contained a standing surface water body; Chott – Dry lake in the Saharan area of Africa; Endorheic basin – Closed drainage basin that has no outflow; Lacustrine plain – Lakes filled by sediment; Lacustrine terraces – A step-like landform; Lake – Large inland body of relatively still water
Land is often defined as the solid, dry surface of Earth. [1] The word land may also collectively refer the collective natural resources of Earth, [2] including its land cover, rivers, shallow lakes, its biosphere, the lowest layer of the atmosphere (troposphere), groundwater reserves, and the physical results of human activity on land, such as architecture and agriculture.

South America is another area vulnerable by desertification, as 25% of the land is classified as drylands [73] and over 68% of the land area has undergone soil erosion as a result of deforestation and overgrazing. [74] 27 to 43% of the land areas in Bolivia, Chile, Ecuador and Peru are at risk due to desertification. In Argentina, Mexico and ...
