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."

2025年1月3日 · Desertification, the process by which natural or human causes reduce the biological productivity of drylands. Such declines may be the result of climate change, deforestation, overgrazing, poverty, political instability, unsustainable irrigation practices, or combinations of these factors.

2024年12月3日 · Desertification has a few varying definitions, but mostly centres around semi-arid, sub-humid lands; in simple terms, it can be described as areas with low or variable rainfall. In addition, there is also the added element of human-induced land degradation owing to an expanding population and rampant deforestation.

2019年5月31日 · Humans are driving the transformation of drylands into desert on an unprecedented scale around the world, with serious consequences. But there are solutions. As global temperatures rise and the...

Desertification is the process by which land turns into a desert. In other words, desertification is when land degrades over time and becomes more arid. Through desertification, previously fertile land becomes infertile and loses biological and economic productivity.

As human activities like agriculture and mining cause land degradation, deserts are getting dryer while lusher, greener areas are transforming into deserts through a process called desertification. In this article, we’ll define what desertification is, its different types, its causes and its effects.

Hot deserts are an important ecosystem with distinct characteristics and adaptations. They provide opportunities for development but also cause challenges such as desertification. is the...

Desertification is a type of land degradation in which a relatively dry land region becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife. It is caused by a variety of factors, such as climate change and human activities.

2020年7月27日 · Desertification, also called ‘desertization’ occurs through a combination of human and natural processes which causes a reduction in productivity of the dryland (a dry region). In simplest of terms; desertification is defined as the loss of …

The process of (forest) desertification is a specific type of combining deforestation and degradation. The UNCCD defines desertification as land degradation in the arid, semiarid, and dry subhumid areas resulting from various factors, including climatic variations and human activities.
