Abstract

Considered the first capital of Ceará, the City of Aquiraz, with unique feature, saves a framework in their environment and cultural history, has beautiful beaches, morphologies and important ecosystems, which are integrated and result in environmental complexity, which is part east coast of Ceará State, located 24.7 kilometers from the capital in and presents with a 10.5 kilometers coastline represented by the beaches of Prainha, Presidio, Iguape and Barro Preto. Attracted by the beauty of this area, caused a sudden growth of the population of Fortaleza corrupt occupying the coastal areas without any infrastructure and environmental support starts at the end of the 1960s. The houses of summer were the starting point in building on the dunes, beach and range of margins of water bodies, followed by public and private investments related to tourism in the implementation o structures of large internationally. Lack of commitment to the environment and disrespect the traditional communities, supported by the public, reflected in a number of environmental damage with changes in coastal sediment dynamics. Accordingly, the research was to understand the local morphodynamic processes to enable trends of erosion and / or advanced line of coast. Tracking promoted the characterization of the variables inherent in the processes of sediment supply and removal of the strip of beach. Involving human activities, a survey was performed of the occupation on the coast and the socioeconomic aspects as well as the application of questionnaires communities and tourists. Problems such as water pollution, deforestation of riparian forest and mangrove, removal of sand dunes, the compaction of beach sand, sediment deficit and advance of the sea, diversion of water courses, the invasion of sand on the homes and social conflicts were negative impacts found in the area by the lack of environmental laws and irrational use of natural resources. It is urgent the adoption of preventive and corrective measures that address the planning and development of coastal management plan for the east coast of Aquiraz creating areas of protection of the environment and vulnerable ecological importance to the occupation to the quality of life and survival of local communities and they will come.
