Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. [1] Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present. [2]
Deforestation is a primary contributor to climate change, [1][2] and climate change affects the health of forests. [3] Land use change, especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels. [4][5] Greenhouse gases are emitted from deforestation ...
Clearcutting, clearfelling or clearcut logging is a forestry/logging practice in which most or all trees in an area are uniformly cut down. Along with shelterwood and seed tree harvests , it is used by foresters to create certain types of forest ecosystems and to promote select species [ 1 ] that require an abundance of sunlight or grow in ...
The effects of climate change are intensifying: longer droughts, a greater loss of biodiversity and more extreme storms and hurricanes. It’s not too late to turn things around.
t. e. Slash-and-burn agriculture is a farming method that involves the cutting and burning of plants in a forest or woodland to create a field called a swidden. The method begins by cutting down the trees and woody plants in an area. The downed vegetation, or "slash", is then left to dry, usually right before the rainiest part of the year.
Tree felling: The selected trees are cut down using chainsaws, harvesters, or other mechanized equipment. The felled trees are then prepared for further processing. Timber extraction: Once the trees are felled, loggers extract the timber from the forest by removing branches and cutting the tree trunks into logs of appropriate sizes for transport.
Reforestation. A forest, six years after reforestation efforts in Panama. Reforestation in progress: Direct-sowing of seed in a burned area (after a wildfire) in the Idaho Panhandle National Forest, United States. Reforestation is the practice of restoring previously existing forests and woodlands that have been destroyed or damaged.
Effects of deforestation on soil erosion. Deforestation has numerous impacts on soil erosion, including: Loss of vegetal cover due to deforestation. Loss of vegetation cover: When trees are cut down, the vegetation cover that protects the soil from flooding wind, and other erosive forces is lost. [7] This exposes the soil to the atmospheric ...
