Trees are cut down for use as building material, timber or sold as fuel (sometimes in the form of charcoal or timber), while cleared land is used as pasture for livestock and agricultural crops. The vast majority of agricultural activity resulting in deforestation is subsidized by government tax revenue . [ 89 ]
The planting of trees on marginal crop and pasture lands helps to incorporate carbon from atmospheric CO 2 into biomass. [53] [54] For this carbon sequestration process to succeed the carbon must not return to the atmosphere from biomass burning or rotting when the trees die. [55] To this end, land allotted to the trees must not be converted to ...
The U.S. Forest Service ignores the climate change impacts of timber targets in our national forests, writes an Asheville biologist.
Logging is the process of cutting down trees for timber or other purposes. [18] [19] [20] It is a major industry in many parts of the world, and it is essential for providing wood for construction, furniture, and other products. There are two main types of logging: Clear-cutting: This is the practice of cutting down all of the trees in an area.
Deforestation in the United States was affected by many factors. One such factor was the effect, whether positive or negative, that the logging industry has on forests in the country. Logging in the United States is a hotly debated topic as groups who either support or oppose logging argue over its benefits and negative effects.
Deforestation in Nigeria can be said to be the process of cutting down trees or clearing forests for either agricultural, commercial, residential, or industrial purposes. [1] In Nigeria, it has become an increasingly important environmental concern as it has adverse effects on the ecosystem, including soil erosion. [2] [3]
Afforestation can also improve the local climate through increased rainfall and by being a barrier against high winds. The additional trees can also prevent or reduce topsoil erosion (from water and wind), floods and landslides. Finally, additional trees can be a habitat for wildlife, and provide employment and wood products. [2]
Cutting trees with the highest value and leaving those with lower value, often diseased or malformed trees, is referred to as high grading. It is sometimes called selective logging, and confused with selection cutting, the practice of managing stands by harvesting a proportion of trees. [9] Logging usually refers to above-ground forestry logging.
