The main aim of this process is to clear areas of forest, woodland or scrub in order to use the soil for another purpose, such as pasture land, arable farming, human settlement or the construction of roads or railways. Many of the world's most prominent forests have suffered significant levels of clearing in recent years, including the Amazon.
The system involves clearing land, by fire or clear-felling, for economically important crops such as upland rice, vegetables or fruits. After a few cycles, the land's fertility declines and a new area is chosen. Jhum cultivation is most often practiced on the slopes of thickly-forested hills. Cultivators cut the treetops to allow sunlight to ...
Time-lapse of Tigercat mulcher clearing brush. Forestry mulching is a land clearing method that uses a single machine to cut, grind, and clear vegetation.. A forestry mulching machine, also referred to as a forestry mulcher, forest masticator, or brushcutter, uses a rotary drum equipped with steel chipper tools ("teeth") or blades to shred vegetation.

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]
Lowland semi-natural grassland is grassland that has not had significant fertilizer or herbicide applied to it, and exists at an altitude of less than 350 metres. [1] Such grasslands are sometimes managed as grazing or as winter food for livestock-cutting for hay or silage.
Deforestation in the Amazon has occurred as a result of farmers clearing land for mechanized cropland. A study based on NASA satellite data in 2006 revealed that the clearing of land for mechanized cropland had become a significant factor in deforestation in the Brazilian Amazon. This change in land use has had an impact on the region's climate.
Deforestation in Central America is one of the environmental problems that is linked to the settlement of agrarian frontier areas by land-seeking farmers and commercial agrarians, who facilitated the conversion of forest land to pasture, more expansion of cash crop like coffee, banana, logging activities, pasture and fuelwoods among other urbanization activities.

An estimated 50,000 acres (200 km 2) of land was also lost due to human-caused forest fires within only a few days. Settlers were often granted land, such as the Homesteads, with a condition that they forfeited it if they didn't clear enough bush. [8] The rising rate of deforestation can be correlated with a sudden rise in sawmill usage.
