Enclosed areas. The role of rural land in sub-regional polycentric areas - "Polycentric systems" identifiable on a sub-regional scale in Italy offer ideas for the study of a particular aspect of these systems. Historically these areas are found in networks of medium sized towns, where the polycentrism is a condition rooted in time and space, a ‘basic premise’ rather than a strategic model for development. An examination of the features of the spaces found in these forms of organisation reveals aspects that may become a starting point for the construction of a framework of co-operation which would solve the problems of the individualist approach that persists at local level. Consideration given to areas of land ‘enclosed’ between urban areas, mainly rural land, may offer an opportunity to draw the attention of groups of local authorities to joint projects to conserve or develop the land.
