In most agricultural systems the same piece of land is cropped continuously, with occasional fallows. Frequently the fields are bounded by hedges, fences or ditches, and the agricultrual landscape is orderd and permanent. In shifting agriculture this is not so. The farmer chooses a patch of forest, secondary or primary, cuts down some of the trees with an axe, leaving only the larger and economically useful, clears the undergrowth with a knife or cutlass, and burns the debris. Crops are sown on the clearing-or swidden-with a minimum or preparation, and receive only cursory attention during growth. After the first harvest crops are sown again for a further year or two, and then the land is left uncropped and colonisation by the natural vegetation is allowed whilst another patch of land is cleared for cultivatrion. Ideally the first clearing will not be used for crops again until it has been under a natural fallow for some years and soil fertility restored. Thus, the essential features of shifting cultivation are, first, the rotation of fields rather than crops, with short periods of cropping alternating with long periods of natural fallow; second, the use of slash-and-burn methods to clear the vegetation, and third, thr maintenance of fertility by allowing the vegetation to regenerate.
