Migrações heterogêneas, superpovoamento e busca de oportunidades imediatas se contrapõem à conservação do patrimônio arquitetônico de Brasília e reorientam o planejamento urbano no Distrito Federal

The occupation of Federal District territory, after fifty years of inauguration of Brasilia, represents an accelerated growth of urbanization process. At the beginning, the projected Plano Piloto received a group of inhabitants, civil servants and their relatives, to be in charge of bureaucracy and to keep the machine functioning. Other waves of people, without professional qualifications, moved by their own interests and immediate necessities, established themselves in the surroundings, denominated satellites towns. These immigrants represent more than half of total inhabitants of Brasília. Their role in the protection and conservation process of the architectural patrimony of Brasilia is undefined and does not seem to belong to their personal preoccupations. Due to the lack of control by official institutions, rural area has being divided into small properties and informal condominiums provoking environmental devastation, destruction of native vegetation of the Cerrado biome, reducing drastically the recharging of aquifers. Until now, the urban planning seems to refer only to monuments, to project new buildings and particularly to increase and improve the traffic system by duplicating lines and viaducts, multiplying and enlarging car parking to privilege the use of private transport instead of public one. In the case of Federal District, at the present, rural and urban area should constitute an indissoluble unit of planning, necessary to determinate and define the limits and the density of territorial occupation because of its restrained capacity to support the population pressure and the intense demand of natural resources.
