Resumen
Given the incessant and clandestine proliferation of housing on the Undevelopable Land of Extremadura, Spain, and that administrative attention to this problem has been scarce, it is inevitable that urban geographers will turn away from the main focus of their study: cities. Thus, a methodology has been designed to discover housing irregularities in the countryside, and to quantify, locate, and date them. To do this, we have digitalized all urban planning in the region and performed sweeps on orthophotos at a maximum scale of 1:1500. Every single dwelling in the region has been detected using this method. The rurbanization in this region means that there has been a change in the urban model that has not been gradual. The fragile and weakened urban network of Extremadura has agglutinated a large part of the population, which has resulted in territorial emptying, but not in a stagnation of artificialization. In fact, the urban network has become increasingly dispersed and isolated because of residential growth outside the limits of Urban and Developable Land. In addition, this growth is eminently clandestine. The worrying results show us that there is an urgent need for the Administration to create and apply a Regional Plan for the Management and Control of Rurban Development.
