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 impact of climate change and human activities on desertification are exemplified in the Sahel region of Africa. The region is characterized by a dry hot climate, high temperatures and low rainfall (100–600 mm per year). [44] So, droughts are the rule in the Sahel region. [45]
Landscape of United Arab Emirates Environmental issues in the United Arab Emirates (UAE) are caused by the exploitation of natural resources, rapid population growth, and high energy demand. The continuing temperature rise caused by global warming contributes to UAE's water scarcity, drought, rising sea level, and aridity. The UAE has a hot desert climate, which is very vulnerable to the ...
For instance, it might be difficult to tell if desertification or desert expansion is the result of climate change or human activity. [19] Desertification in Africa is exacerbated by human factors such as deforestation, overgrazing, and unsustainable farming methods such as monoculture and excessive use of chemical fertilizers.
Iran's regional climates vary from the hot, arid deserts in the south and east to cooler, milder conditions along the Caspian Sea in the north, and temperate climates in the western-south Zagros Basin and southern coastal areas. This diversity contributes to a range of natural hazards, including floods, landslides, and droughts.
The average annual precipitation in low latitude deserts is less than 250 mm. Relative humidity is very low – only 10% to 30% in interior locations, and even the dewpoints are typically very low, often being well below the freezing mark. Some deserts do not have rainfall all year round, they are located far from the ocean.
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.
Desertification is one of the issues of environmental concern in Nigeria, particularly the northern part of the country. According to UNEP [4] in 1993, Northern Nigeria has one of the highest rates of deforestation in the world at about 3.5%, caused by land degradation, increase in agricultural intensity, over-grazing of livestock, and demand for fuel by cutting down trees.
