A system of agriculture in which plots of land are clearly (generally through slash and burn" methods) and cultivated temporarily before they are abandoned for another plot, and allowed to regenerate nutrients in the soil. Swidden: land cleared through slash and burn and ready for cultivation. Commercial farming: large scale production, growing food for sale on the market. Green revolution: associated with genetically modified organisms (gmos) that produce higher yielding crops, large increase in crop production, mostly in developing countries, 1960s india and 1r8, 1982 1r36.
