The system involves clearing land, by fire or clear-felling, for economically important crops such as upland rice, vegetables or fruits.

Cultivators cut the treetops to allow sunlight to ...
However, on US farmland, soil erosion is much less on land used for livestock grazing than on land used for crop production. According to the US Natural Resources Conservation Service , on 95.1% of US pastureland, sheet and rill erosion are within the estimated soil loss tolerance , and on 99.4% of US pastureland, wind erosion is within the ...
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 ...

Shifting cultivation is an agricultural system in which plots of land are cultivated temporarily, then abandoned while post-disturbance fallow vegetation is allowed to freely grow while the cultivator moves on to another plot. The period of cultivation is usually terminated when the soil shows signs of exhaustion or, more commonly, when the ...
Wood pasture, one of the oldest land-use practices in human history, [6] is a historical European land management system in which open woodland provided shelter and forage for grazing animals, particularly sheep and cattle, as well as woodland products such as timber for construction and fuel, coppiced stems for wattle and charcoal making and ...
