Evolução da paisagem como ferramenta para a consolidação de políticas públicas sustentáveis no setor de promontório do distrito de Jacaúna-Planície Costeira do município de Aquiraz/CE.

Abstract

The coastal area reveals a complex and vulnerable environment controlled by natural processes that act in maintaining the dynamic equilibrium. These factors express a landscape with large production potential, being privileged to the development of social, cultural and economic activities space. This reflects the population density, diversity of uses and socioeconomic interests in environmental systems and forms of occupation, largely contributing to the impairment of the structure and functioning of the landscape. This research is directed to the study of the coastal plain of Jacaúna district, municipality of Aquiraz / Ce. The area represents a geomorphological cut on the east coast of Ceará State to 44 km from the capital, inserted between latitudes 3 ° 58 '4'' S and 3 º 56' 6 '' S and longitude 38 º 15 ' 4 '' W and 38 º 18 ' 2 '' W , totaling an area of 29.50 km ². Because it is a sector of the promontory, where the mechanism occurs bypass acts as an important regulator of sand belonging to the coastal plain of the county environmental systems. The misuse of this area may incur potential risks to sediment availability and affect environmental systems linked to the very quality of life of coastal communities. In this perspective, the main objective was to analyze the evolution of the landscape and its environmental implications in the current configuration, aiming to contribute to the consolidation of sustainable public policies. Adopted the integrated approach based on the systemic method, with emphasis on the evolutionary - dynamic analysis landscape. To do so: bibliographic and cartographic surveys; analysis and integration of geo-environmental components; systems and cartographic mapping of interpretation (1958, 1970 and 2009) were performed. The results revealed the occurrence of sharp erosion linked to the natural action of coastal processes, which resulted in significant reduction of the areas of the beach / backshore. In 2009, human interventions helped to accentuate this framework through irregular constructions and improper management of natural resources. The stretch of beach and dunes fields stand out as the units most affected landscape. This scenario shows the need for effective and participatory actions related to monitoring of the activities and development as well as the appreciation of natural environments.
