A farming technique for crop cultivation without irrigation in areas of low and variable rainfall. Most common is fallowing in which two seasons\' rainfall is reserved for one crop, with mulching and frequent weeding. Low-rainfall areas are vulnerable to erosion, and thus soil conservation methods are essential. Dry farming areas can have only a narrow range of crops and low yields. Dry farming is a long established practice in the Near East, North Africa, and north-west India. These methods were instrumental in the extension of crop cultivation into the semi-arid areas of North (and South) America and Australia by European settlers in the nineteenth century. (SW)
