Áreas ecologicamente estáveis como instrumento de planejamento ambiental

Abstract

The population growth phenomenon, coupled with recent urbanization, is seen in all continents and generates huge pressures on the physical and biotic environment, resulting in floods in several areas, desertification in others, and also various forms of pollution that cause serious problems to human health. It is appropriate to ask, what actions can be implemented in consolidated urban areas to improve the quality of life in this environment? What growth alternatives present themselves to today's society in order to keep an acceptable level of environmental quality in urban centers? A possibility is presented herein, stemming from the application of the Biotope Area Factor (BAF; www.stadtentwicklung.berlin.de) to an area of a Brazilian municipality. Current growing waterproofing requirements fur lots of the area were assesed, comparing them with those that would be desirable by the implementation of the BAF. The associated costs of this deployment are also discussed.
