What is the afforestation?

The processing is planting trees to create a forest on the ground that is not a forest. It is different from the afforestation that planted trees where the forest has been exhausted. The main purposes for implementation are commercial forestry and restoration or environmental protection. The areas where it is done are known as plantation forests . Harvesting trees from plantation forests helps reduce deforestation in natural forests. On the other hand, there may be environmental consequences if this tree farming is carried out incorrectly. Fast growing trees, which often choose for plantation forests, consume large amounts of water and can exhaust the water sources of the area. Some types of trees also change the physical or chemical properties of soil that can damage indigenous species. Thus, sustainable commercial rates did not damage the local ecosystem.

Sustainable afforestation is also essential if it isimplemented for environmental purposes. Suitable types and quantities of trees to be planted differ depending on the environment, climate and purpose of creating forested areas. The main environmental purposes include soil protection and improving water quality. For example, the trees can be used to prevent soil erosion and reduce polluted runoff into nearby water bodies. Trees can also be planted to form windbreakers. For example, during a bowl in a dust bowl in the Large Plain of the United States, planting long rows of original trees was supported to protect crops from wind and reduce the loss of topsoil.

afforestation is sometimes considered to be a method for stopping or slowing down desertification. Desertificazhozhozhozhozhozhozhoje soil in arid climate is due to the loss of vegetation and soil moisture. If it is done correctly, the creation of forests in areas that are endangered by desertification, slow erosion and reduce its spread. In the Gobi desert in China and the Sahara in Africa areIn the Gobi desert, efforts to use afforestation to prevent the desert to prevent more land.

In China, at least 3,600 square kilometers of land from the Gobi desert are taken over each year. The green wall is a massive, approximately 2,800 kilometers long efforts to plant trees to prevent it. A similar large green wall stretching from Senegal to Djibouts is designed to help stop the spread of the Sahara. However, critics of both claim that central planning would not be as effective as supporting local sustainable methods of agriculture, as such projects require very changing local conditions.
