Land degradation and desertification

The deterioration of land has a negative impact on the extreme weather conditions, especially on the production and provision of drought, pollution, human activities, food production, livelihoods and other ecosystem products and services that reduce soil quality and land use, It is caused by various factors.

By the increase and integration of pressure by extreme weather phenomena such as agricultural land and livestock production (excessive cultivation, overgrazing, forest conversion), urbanization, deforestation, and drought and coastal marginal landmines, land deterioration It accelerated. Desertification is a form of land degradation, fertile land becomes a desert.

These social and environmental processes highlight the world's cultivated land and meadows. And it is essential to supply food and water and good quality air. Land degradation and desertification can affect human health through complicated routes. Along with the deterioration of the land, deserts are expanding in some areas, food production has decreased, the supply of water has been exhausted, and the area where the population is more friendly is being pressured. The impact on desertification on health is as follows.

The GEO-4 evaluation is a comprehensive and authoritative UN report on the environment, development and human welfare, providing insightful analysis and information for decision making.

Tackle the land issues identified by UNEP regional groups and emphasize that human pressure on land resource demand is the cause of land degradation

Another effect is to change the scenery. It can be divided into two different problems: land degradation and desertification. Land degradation simply means that the soil quality is getting worse. This phenomenon is the result of excessive cultivation and poor land use. On the other hand, desertification means the growth of deserts and sandy lands. According to the regulations of the United Nations Environment Program, approximately 31,000 square miles of land will be dessert per year. Another major impact is the increased danger of drought, fire, food and species extinction. Climate change causes water circulation above and below the surface of the earth, droughts and floods occur more frequently, become more severe and widely spread. According to Pakistan government data, flooding in 2010 directly affected about 20 million people, most of them by population.

Activities that have already deteriorated due to unsustainable human activities in areas already vulnerable and natural dislikes such as drought and floods will cause land degradation and desertification. Kenya's 2002 National Action Plan on Prevention of Desertification is reported as follows. "The current ecological conditions in arid regions are harsh and fragile.These conditions are exacerbated by the influx of people from frequent drought and potential areas to dry areas.Size of the plot worsens them I will let you.
