shifting agriculture(redirected from Slash and burn)
Also found in: Dictionary, Idioms, Wikipedia.
slash and burna type of nonintensive agriculture, practised in tropical forests where soil fertilities are low. It involves the clearing and burning of existing vegetation in order to cultivate crops. When the soil becomes depleted, or earlier, the society moves on to repeat the process elsewhere, often leaving the forest to regrow. Although perhaps ecologically sound, such forms of agriculture are threatened by economic development. Compare HUNTER-GATHERER.
