Ao longo da planÃcie costeira de Icapuà foi definido um complexo conjunto de unidades geoambientais originado pela interdependÃncia evolutiva dos variados componentes morfolÃgicos e regida pelos fluxos de matÃria e energia orientados pelas flutuaÃÃes do nÃvel relativo do mar e mudanÃas climÃticas durante o QuaternÃrio. Para definir a integraÃÃo destes componentes elaborou-se uma proposta de zoneamento geoambiental dessa planÃcie localizada no extremo leste do Estado do CearÃ, nordeste do Brasil. O principal objetivo foi o de, atravÃs dos mapas temÃticos em escala de detalhe (geolÃgico, geomorfolÃgico, unidades de paisagens), definir as bases geoambientais para gestÃo planejada dos sistemas naturais. Esses resultados foram alcanÃados atravÃs da realizaÃÃo de um amplo levantamento bibliogrÃfico, atividades em campo para o mapeamento e a utilizaÃÃo de imagens de satÃlite de alta resoluÃÃo. Aliado à elaboraÃÃo dos mapas temÃticos e zoneamento ambiental foi possÃvel realizar estudos quanto à dinÃmica dos elementos socioeconÃmicos e ambientais, os quais possibilitaram a elaboraÃÃo de um diagnÃstico socioambiental com Ãnfase em Ãreas que foram consideradas de risco potencial. Com a definiÃÃo das vulnerabilidades e potencialidades dos componentes morfolÃgicos da planÃcie costeira, foram agrupadas Ãreas relativamente homogÃneas e sugeridas medidas de gestÃo para melhoria da qualidade ambiental e vida das comunidades litorÃneas. Esses resultados alcanÃados fazem parte do projeto âDe Olho na Ãguaâ desenvolvido pela FundaÃÃo Brasil CidadÃo em parceria com o Programa de PÃs-graduaÃÃo em Geografia da UFC com o apoio do Programa Petrobras Ambiental e da FundaÃÃo Cearense de Apoio ao desenvolvimento cientÃfico e TecnolÃgico (Funcap). / This dissertation analyzes the sustainability of the carcinoculture in the city of Fortim-CearÃ, taking into consideration environmental, social and technological aspects. The research aimed at identifying the main handlin
g practices and the technology that has been adopted in the shrimp culture farms, and its contribution to a sustainable development of the activity. The study presents some forms of technology and handling practices that can be adopted by the farms, which are considered less environmentally impacting, and it also identifies the main impacts generated by the activity. Primary and secondary data were
used. The primary data were obtained by means of an empirical research carried out in the city of Fortim, during the months of April and August, 2005. During these visits, questionnaires were applied, with semi-structu
red and open questions. It was also possible to carry out interviews with representatives of governmental agencies and the business community. Secondary data were obtained by means of bibliographical research comprising theses, books and articles on the issue, as well as documents such as reports, Codes of Conduct, Federal and State govern
ment directives, and assessments made by governmental agencies in charge of regulating and supervising the activity. In this study, tabular and descriptive analysis techniques and a modified version of the âForest Service of
United States Agricultural Department (1986) methodology were applied. These methods made it possible to transform the qualitative variables into quantitative ones, through
numerical values and weights so as to obtain a Significance Index of the technological, environmental and social variables. Upon the results obtained by these Indexes, it was possible to assess that the carcinoculture in the region is not developing on a sustainable basis, rejecting, therefore, the proposed hypothesis, according to which the handling practices and the technology that has been used in these farms are contributing for the development of the activity in a way that is in harmony with the environment. In spite of the existence of some initiatives that suggest
that the sector is starting to take into consideration environmental matters, it is possible to affirm that the actions carried out by the sectorâs main entities have
not been able to effectively promote the necessary changes
in the behavior and conduct of the business, neither has it been able to call the attention to the importance of preserving the environment.
