No. of bitstreams: 1 PatricaPM_DISSERT.pdf: 3860742 bytes, checksum: e010848d8e0374d083ea04d872a52dc2 (MD5) Previous issue date: 2011-08-12 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / The mangrove ecosystem has a great importance to maintaining marine biodiversity, and to the livelihoods of communities living around it. Despite its importance, many mangrove areas have been extensively cleared and converted to other uses. There are few places where communities can retain their traditional uses of mangrove. A good example of conservation of traditional costumes are the fishing communities of the Sustainable Development Reserve (Reserva de Desenvolvimento Sustent?vel RDS) Ponta do Tubar?o. The creation of the reserve came from the own population, and the devastation of a mangrove area, which would be destined for activity shrimp, was one of the reasons that led the population to ask authorities the establishment of a legally protected area. Thus, this study aimed to investigate the environmental perception of the fishing communities of RDS Ponta do Tubar?o with respect to the mangroves in a biological, ecological and social perspective as well as evaluate the influence of the reserve in the mangrove conservation and quality of life. To meet objectives of this study was required the appropriation of some method and approaches of ethnosciences and environmental perception. Data were collected through direct observation, and semi-structured interviews. Through content analysis found that the population has a strong dependence on the mangrove ecosystem, as well as provides a good ecological knowledge of ecosystem functions. It was also found that the reservation has a good performance in the conservation of the mangroves; however, need to outline strategies to conciliate both the biological and cultural conservation. / O manguezal ? um ecossistema de grande import?ncia, tanto para manuten??o da biodiversidade marinha, quanto para a subsist?ncia das comunidades que moram no seu entorno. Apesar de sua import?ncia, in?meras ?reas de mangues t?m sido intensamente devastadas e convertidas para outros usos. S?o poucos os lugares em que as comunidades conseguem preservar os usos tradicionais dos manguezais. Um bom exemplo da preserva??o dos costumes tradicionais s?o as comunidades pesqueiras da Reserva de Desenvolvimento Sustent?vel Estadual Ponta do Tubar?o, localizado no litoral setentrional do Estado do Rio Grande do Norte. A cria??o da reserva partiu da pr?pria popula??o e a devasta??o de uma ?rea de manguezal, ao qual seria destinada ? atividade de carcinicultura, foi um dos motivos que levou a popula??o solicitar ?s autoridades o estabelecimento de uma ?rea legalmente protegida. Desse modo, este trabalho objetivou registrar o valor biol?gico, ecol?gico e social dos manguezais na percep??o dos pescadores, marisqueiras e catadores de caranguejo, bem como avaliar a influ?ncia da reserva na conserva??o do manguezal e qualidade de vida da popula??o. Para atender os objetivos do trabalho fez-se necess?ria a apropria??o de alguns m?todos e abordagens das etnoci?ncias e percep??o ambiental. Os dados foram obtidos por meio de observa??o direta e entrevistas semiestruturadas. Atrav?s da an?lise de conte?do constatou-se que a popula??o apresenta uma forte depend?ncia do ecossistema manguezal, bem como apresenta um bom conhecimento ecol?gico das fun??es do ecossistema. Constatou-se tamb?m que a reserva apresenta uma boa atua??o na conserva??o do manguezal, entretanto, precisa tra?ar estrat?gias, que consiga conciliar a conserva??o biol?gica e cultural.
