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."
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.
Desertification's detrimental effects on ecosystems and biodiversity can have far-reaching consequences for industries like tourism and ecotourism, which rely on healthy ecosystems to attract tourists. Desertification has enormous economic ramifications in Africa, necessitating persistent efforts to minimize the effects of desertification ...
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
Climate change is a significant contributor to desertification in Ghana. [19] The country is especially susceptible since it relies heavily on rain-fed agriculture and has inadequate capacity for mitigation and adaptation. Climate change has had a negative influence on the environment, the economy, and society as a whole.
Examples of effects on some biome types are provided in the following. [clarification needed] [where?] Research into desertification is complex, and there is no single metric which can define all aspects. However, more intense climate change is still expected to increase the current extent of drylands on the Earth's continents.
The environmental impact of fishing can be divided into issues that involve the availability of fish to be caught, such as overfishing, sustainable fisheries, and fisheries management; and issues that involve the impact of fishing on other elements of the environment, such as by-catch and destruction of habitat such as coral reefs.

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.
