'''Slash-and-burn agriculture''' is a rotating cultivation [[technique]] in which trees are cut down and burned in order to clear land for temporary [[agriculture]]; the [[land]] is used until its productivity declines at which point a new plot is selected and the process repeats; this [[practice]] is sustainable while population levels are low and time is permitted for [[regrowth]] of natural vegetation; conversely, where these conditions do not [[exist]], the [[practice]] can have disastrous consequences for the environment. | '''Slash-and-burn agriculture''' is a rotating cultivation [[technique]] in which trees are cut down and burned in order to clear land for temporary [[agriculture]]; the [[land]] is used until its productivity declines at which point a new plot is selected and the process repeats; this [[practice]] is sustainable while population levels are low and time is permitted for [[regrowth]] of natural vegetation; conversely, where these conditions do not [[exist]], the [[practice]] can have disastrous consequences for the environment. |
