Abstract

In order to evaluate the urban evolution that occurred in the vicinity of the estuary of the Rio Coco/Fortaleza/ CE and its negative impacts in the period between 1985, 1996 and 2007, we performed an analysis from multitemporal images of TM/Landsat-5 respective years in a GIS environment. 9 units were defined use and land cover (Urban Area; River; Natural Vegetation; Plain hypersaline; Ponds and wetlands, dunes, beach range; Intermittent inter dune ponds; Banks of Sand), which were quantified and compared. These results suggest the need for systematic monitoring of urban sprawl, for identification and control of pollution loads sources identical and commercial to promote environmental education to expand the effective oversight of the police and the Ecological Park its suitability for the National System of Conservation Units - SNUC.
