ABSTRACT
Many planning officials, ethnologists, sociologists and other students of Man in his environment, as well as many geographers, regard regions as facts of the earth's surface. For them a division into regions is not a means to the end of describing that surface: the end is to define and describe the regions which actually exist. Within the cultivated area, certain criteria can be chosen and regions defined accordingly. One method is to map the area where a certain crop-combination is predominant, say the wheat, barley, roots and clover rotation of East Anglia or the wheat, vines and olives of the Mediterranean area. Study of large-scale land-use maps will show how valid farming regions are. Each field may be marked as having a different use from its neighbours, but the wider view will show some areas where crops or orchards are much more common than permanent grass for dairy cattle.
