slash and burn
Simple agricultural method whereby natural vegetation is cut and burned, and the clearing then farmed for a few years until the soil loses its fertility, whereupon farmers move on and leave the area to regrow. Although this is possible with a small, widely dispersed population, as in the Amazon rainforest for example, it becomes unsustainable with more people and is now a cause of deforestation.
