Abstract
The hydrographic basin of the Guaribas River in the municipalities of São Gonçalo do Amarante and Caucaia, in the northeastern Brazilian state of Ceará, presents a complex landscape, composed of mobile and fixed dune fields, hydrological resources (lakes, floodplains, and coastal plains), and coastal plateaus. Alterations in the use of the soil within this landscape were evaluated between 1958 and 2012, considering the conservation of vegetation cover, urban development, and the expansion of industrial installations. This assessment was based on the integration of remote sensing data with spatial data, which represent the principal transformations of the landscape. The results of the analysis indicate that (i) there was a reduction in the vegetation cover on the fixed dunes, reflecting the expansion of urban and industrial development, (ii) the mobile dune field was affected by the expansion of urban development, (iii) there was an increase in the occupation of the margins of hydrological resources by both urban development and industrial installations, and (iv) the vegetation of the coastal plateaus was also reduced by the ongoing expansion of urban and industrial development.
