Manguezal do estuÃrio Barra Grande em IcapuÃ-CE: da degradaÃÃo ao processo de recuperaÃÃo e mudanÃa de atitude / Great mangrove estuary bar Icapui -CE : degradation to the recovery process and attitude change

Josà de Arimatea da Silva 12 July 2012 (has links)
CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / The research conducted in Barra Grande, Icapuà â CE analyzed in a systematic way the geo environmental aspects of Barra Grande estuary with emphasis on mangrove and other coastal systems associated with it. The methodological foundations were related to the definition of the dynamic processes by identifying flows of matter and energy of the geo environmental diagnosis to highlight the importance of the mangrove estuary and in the maintenance of other coastal ecosystems and biodiversity. In this process, a space-time analysis was made through the preparation of thematic maps and charts showing the occupation of mangrove by economic activities generating impacts (salt, fish and shrimp) that led to environmental degradation and impairment of the ecosystem and its biodiversity. We also analyzed the social mobilization initiatives and environmental education process that arose from the joints of youth groups and NGOs that triggered political and environmental movements in Icapuà generators of change of attitude toward the use and conservation of mangroves. Also noteworthy is the implementation of projects for the rehabilitation of degraded areas and conservation of the wetland, identified and analyzed to provide data for interpreting the potential for social mobilization for the conservation of lowland environmental systems under study. Finally, the research allowed the development of a proposed environmental zoning of the estuary and mangrove swamp, with reference to the demarcation proposed by the Municipal Law No. 298/2000 which established the Environmental Protection Area (EPA) of Barra Grande / A pesquisa realizada na Barra Grande no municÃpio de IcapuÃ-CE, analisou deforma sistÃmica os aspectos geoambientais do estuÃrio Barra Grande com Ãnfase no manguezal e os demais sistemas costeiros associados. Os fundamentos metodolÃgicos foram relacionados com a definiÃÃo dos processos dinÃmicos atravÃs da identificaÃÃo dos fluxos de matÃria e energia do diagnÃstico geoambiental para evidenciar a importÃncia do estuÃrio e do manguezal na manutenÃÃo dos demais ecossistemas costeiros e da biodiversidade. Neste processo, fez-se a anÃlise espaÃo-temporal atravÃs da elaboraÃÃo de mapas e cartas temÃticas evidenciando a ocupaÃÃo do manguezal por atividades econÃmicas geradores de impactos (salinas, pesca e carcinicultura) que levaram à degradaÃÃo ambiental e ao comprometimento do ecossistema e sua biodiversidade. TambÃm foram analisadas as iniciativas de mobilizaÃÃo social e do processo de educaÃÃo ambiental que surgiram de articulaÃÃes de grupos de jovens e ONG que desencadearam movimentos ambientalistas e polÃticos em Icapuà geradores da mudanÃa de atitude diante dos usos e preservaÃÃo do manguezal. Destaca-se tambÃm a implantaÃÃo de projetos voltados para a recuperaÃÃo das Ãreas degradadas e conservaÃÃo do manguezal, identificados e analisados de modo a fornecerem dados para interpretar o potencial social de mobilizaÃÃo para a conservaÃÃo dos sistemas ambientais da planÃcie em estudo. Por fim, a pesquisa possibilitou a elaboraÃÃo de uma proposta de zoneamento ambiental do estuÃrio e manguezal, tendo como referÃncia a demarcaÃÃo proposta pela Lei Municipal N 298/2000 que criou a Ãrea de ProteÃÃo Ambiental (APA) da Barra Grande.
