Land use, land-use change, and forestry (LULUCF), also referred to as Forestry and other land use (FOLU) or Agriculture, Forestry and Other Land Use (AFOLU), [3] [4]: 65 is defined as a "greenhouse gas inventory sector that covers emissions and removals of greenhouse gases resulting from direct human-induced land use such as settlements and ...
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]
Forest ecology shares characteristics and methodological approaches with other areas of terrestrial plant ecology, however, the presence of trees makes forest ecosystems and their study unique in numerous ways due to the potential for a wide variety of forest structures created by the uniquely large size and height of trees compared with other ...
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 during the burning of forest biomass and decomposition of remaining plant material and soil carbon.
Forest cover in the Eastern United States reached its lowest point in roughly 1872 with about 48 percent compared to the amount of forest cover in 1620. The majority of deforestation took place prior to 1910 with the Forest Service reporting the minimum forestation as 721,000,000 acres (2,920,000 km 2) around 1920. [2]
Demand for forest products, especially wood, resulting from earlier deforestation, also creates market incentives to plant trees and more effectively manage forest resources. [12] Due to forestry intensification, higher forest productivity saves remaining forests from exploitation pressures. [ 13 ]
Stand density management diagrams are used in forest management and designed to use a current stand's density to project its future yield. [2] One major reason for the effectiveness of density management diagrams is the relatively low effect of site variance on the diagram's shape.
Forestry is practiced in plantations and natural stands. [2] The science of forestry has elements that belong to the biological, physical, social, political and managerial sciences. [3] Forest management plays an essential role in the creation and modification of habitats and affects ecosystem services provisioning. [4]
