RESUMO:

Rivers are important structural elements of the urban fabric, but they also suffer greatly in this process. Urbanization poses serious threats to their own sources, generating a conflictive relationship where, while the city basically need water to survive, it pollutes, channels and waterproofs its rivers and floodplains, deforestation of riparian zones and destroys the possibilities to reinfiltrating water in the soil. The water sources recharging process cannot keep up with the continuous increase in the demand for water in the cities, causing systematic lowering in the reservoirs and, consequently, scarcity. The city of Natal, in turn, has an ambiguous relationship with its rivers, placing them as important sources of supply and development while, on the other hand, let them suffer with an incompatible occupation process with the existing urban infrastructure support and with the environmental characteristics of the territory, receiving waste from industrial and agricultural activities and numerous clandestine sewage connections throughout their courses. The Pitimbu River shows itself to the city already in the middle of century XX, when its growth in the south direction reaches then this new natural barrier. What happens, then, when the city meets this River? With rural characteristics and slow growth, the advance of urbanization in the region took a breath from the 1970s. The Pitimbu River cuts along its course parcels of territory of the municipalities of Natal, Parnamirim and Macaíba, members of the Natal Metropolitan Region (NMR); And its microbasin, which is part of the Pirangi River basin, constitutes an important recharge area for one of the main sources of drinking water for NMR - however, the phenomenon of urban occupation compromises the development of river's environmental functions, with deforestation, erosion, pollution and silting evident at various points along its course, as well as the pressure of the real estate market and informal occupation in the area. At this point, we must ask: how do the characteristics of urban occupation and urban development interfere with the capacity of recharge of its water sources? Is it possible to reconcile the spatial planning process with the preservation of the water cycle? Considering, on the one hand, the hydrographic basin as a basic territorial planning unit (given its capacity for integration between the natural, socioeconomic and cultural aspects of the territory); and on the other hand the set of public policies and urban planning instruments currently in existence, this study aims to analyze the urban development process from the perspective of the water cycle, based on the observation of the relationship between the configuration of the occupation of the territory and the biophysical characteristics of the environment. Thus, it is sought to contemplate the urban site as a whole, including the natural aspects and its articulation with human action, and for this the combination of the techniques of cartography and geoprocessing provides an integrated analysis of the territory, possible thanks to the ease of representation of the cartographic spatiality of the analyzed phenomenon and the integration of the data by the thematic mapping. The aim of this study is to provide subsidies for the regional planning of the region, serving as the basis and orientation for the formulation of public policies adequate to the capacity of supporting the environment and the installed or planned infrastructure conditions; bearing in mind an occupation based on urban-environmental criteria that seek to reconcile the growth and development needs of cities with the preservation of their water supplies and the maintenance of ecological balance.
