The sea cliffs are important morphologies in the coastal landscape of Ceará, setting in steep and unstable slopes in coastal areas affected by wind, rain and especially marine flow, and its associated training mainly to the deposition of the Barreiras Group sediments. On the coast of Fortim, the sea cliffs are distributed in the coastal plain and along the left bank of the river Jaguaribe, where you can see the highest population density and concentration of infrastructure associated with the tourism. The research is inserted in the municipality of Fortim, the main spatial extent its sea cliffs coastline, compartmentalized into three sectors of study, occupying in total an area of 7.089.3 hectares (70, 89 km²), for which was held analysis of landscape dynamics in an integrated way, linking the environmental aspects of the socioeconomic conditions in order to contribute to environmental planning and management that are consistent with the reality in question. The research is headed in the analysis of the dynamics and typology of the landscape, following thus systemic assumptions from the theoretical and methodological foundations of Geoecology landscape. The research stages permeated the field research for application checklist and collection of environmental data, granulometric analysis of sediments, water analysis and cartographic products, which used RapidEye 2013 satellite images on the scales of 1: 40,000 and 1: 80,000. They were, in the stages mentioned, the sea cliffs of Fortim are formed by rocks of the Barreiras Group and in some sectors are associated with Formation Tibau rocks; generally they consist of medium sands and strongly cemented sandstones. Regarding the forms of use and occupation of coastal, activities were identified developed in Permanent Preservation Areas, such as shrimp farming in fluviomarinha plain of the river Pirangi, allotments and second homes, mainly on the tops of sea cliffs, contributing mainly to the mischaracterization of the landscape and the privatization of space. In some sectors, there is no occupation of the sea cliffs, however the small stretch of beach strip makes the vulnerable side to wave action. It was also noted, through physical, chemical and microbiological analyzes, the quality of water from community wells is committed to consumption, especially in areas of high population density. In this sense, one should promote the management of the area, being necessary to know the coastal carrying capacity with cliffs with a view to preventing and minimizing possible negative influence on natural systems and human populations that live in the surrounding areas of these environments.
