A variety of crops can thrive in these irrigated oases. Sugar cane is a very water-intensive crop mostly harvested in tropical regions. However, sugar cane is also harvested in the deserts of Pakistan and Australia. Water for irrigation is transported from hundreds of kilometers away, or drilled from hundreds of meters underground. New technologies are also being developed to combat desertification. “ Nanoclay” is a substance sprayed on desertsands that acts as a binding agent. Nanoclay keeps the sand moist, clumping it together and preventing it from blowing away.

Silvopasture (integrating trees, forage and grazing) can help to stop deforestation in the region. [132]Is the World Full or Empty?". Story Maps. Archived from the original on 15 January 2022 .

England should not possess a desert, or anything remotely resembling one; the hint of such a thing felt dangerous and subversive. Deserts surely belong in places that are remote and far away from this green and pleasant land, or from this over-civilised time. There should be no place for them here. And yet here one (almost) is. Between Covid-19 and climate change, the practicalities – and ethics – of travel are more fraught than ever before. South Saharan steppe and woodlands". Terrestrial Ecoregions. World Wildlife Fund .

The green leaf area of plants and trees in the rainforest varies by about 25% as a result of seasonal changes. Leaves expand during the dry season when sunlight is at a maximum, then undergo abscission in the cloudy wet season. These changes provide a balance of carbon between photosynthesis and respiration.

The Great Green Wall, participating countries and Sahel. In September 2020, it was reported that the GGW had only covered 4% of the planned area. [38]The deathstalker scorpion can be 10cm (3.9in) long. Its venom contains large amounts of agitoxin and scyllatoxin and is very dangerous; however, a sting from this scorpion rarely kills a healthy adult. The Saharan silver ant is unique in that due to the extreme high temperatures of their habitat, and the threat of predators, the ants are active outside their nest for only about ten minutes per day.

Death Valley, the lowest and driest place in North America, is in the rain shadow of the Sierra Nevada mountains. The South Saharan steppe and woodlands ecoregion is a narrow band running east and west between the hyper-arid Sahara and the Sahel savannas to the south. Movements of the equatorial Intertropical Convergence Zone (ITCZ) bring summer rains during July and August which average 100 to 200mm (4 to 8in) but vary greatly from year to year. These rains sustain summer pastures of grasses and herbs, with dry woodlands and shrublands along seasonal watercourses. This ecoregion covers 1,101,700 square kilometres (425,400sqmi) in Algeria, Chad, Mali, Mauritania, and Sudan. [46]

With their variations in temperature, rainfall, elevation, and soil, these regions harbor distinct communities of plants and animals.

When groundwater doesn’t seep to the surface, people often drill into the ground to get to it. Many desert cities, from the American Southwest to the Middle East, rely heavily on such aquifers to fill their water needs. Rural Israeli communities called kibbutzim rely on aquifers to furnish water for crops and even fish farming in the dry Negev Desert. Egypt became independent of Britain in 1936, although the Anglo-Egyptian treaty of 1936 allowed Britain to keep troops in Egypt and to maintain the British-Egyptian condominium in the Sudan. British military forces were withdrawn in 1954. Wynne, R.H.; Joseph, K.A.; Browder, J.O.; Summers, P.M. (2007).
