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 ...
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.

Through the turn of the 20th century, settlers continued to use fire to clear the land of brush and trees in order to make new farm land for crops and new pastures for grazing animals—the North American variation of slash and burn technology—while others deliberately burned to reduce the threat of major fires—the so‑called "light ...
[1] [29] [30] Targeted grazing is often used in combination with other techniques such as burning, herbicide applications or land clearing. Targeted grazing can rival traditional herbicide and mechanical control methods for invasive plants from invasive forb to juniper trees, and has been used to reduce fine fuels in fire prone areas. [31] [32 ...
Deforestation is clearing the Earth's forests on a large scale worldwide and resulting in many land damages. One of the causes of deforestation is clearing land for pasture or crops. According to British environmentalist Norman Myers , 5% of deforestation is due to cattle ranching , 19% due to over-heavy logging , 22% due to the growing sector ...
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.
In shifting agriculture, after two or three years of producing vegetable and grain crops on cleared land, the migrants abandon it for another plot. Land is often cleared by slash-and-burn methods—trees, bushes and forests are cleared by slashing, and the remaining vegetation is burnt. The ashes add potash to the soil.
