desertization的意思|示意

【英语单词desertization的用法讲解】

Desertification, also referred to as desertization, is a type of land degradation by which a region becomes increasingly arid and dry, reducing the ability of vegetation to grow and affecting the ability of the land to support agriculture and other human activities. Desertification is a global problem, with many countries and regions facing serious environmental, economic and social consequences due to the effects of desertification.

Desertification has many causes, including over-farming, overgrazing, deforestation, climate change and human activities. Over-farming and overgrazing can lead to soil erosion and the destruction of vegetation, which reduces the moisture in the air and decreases the availability of nutrients in the soil. Deforestation can reduce the amount of rainfall in an area, as the trees are no longer there to absorb water from the land and reduce the rate of evaporation. Climate change can also alter weather patterns, leading to either increased temperatures or less precipitation. Human activities, such as irrigation and the use of fertilizers, can also lead to soil erosion and degradation.

In order to combat desertification, governments and organizations need to take action to protect the land. This can be done through the use of sustainable farming practices, such as crop rotation and avoiding over-farming and overgrazing. It is also important to protect and promote the growth of vegetation, as this can reduce evaporation and increase the amount of moisture in the air. Governments can also work to increase access to clean water and create policies that reduce human activities, such as over-grazing, that can contribute to desertification.

In summary, desertification is the process by which land becomes increasingly arid and dry due to a variety of factors, including over-farming, overgrazing, deforestation, climate change and human activities. To combat desertification, governments and organizations need to take action to protect the land through sustainable farming practices, protecting and promoting the growth of vegetation and reducing human activities that can contribute to desertification.
