Shifting Cultivation
(slash-and-burn agriculture) The traditional agricultural system of semi-nomadic people, in which a small area of forest is cleared by burning, cultivated for 1-5 years, and then aban¬doned as soil fertility and crop yields fall and weeds encroach. Ideally vegetation *succession subsequently returns the plot to *climax woodland, and soil fertility is gradually restored. Shifting cultivation of this type was once practised worldwide but in modern times it has been primarily associated with tropical rain-forest areas.
