Resumo: The present work was carried out in order to study the agro ecosystems sustainability in the São Francisco River estuary, through a system analysis from the characterization of the structure, function and properties (sustainability, productivity, stability, equitability and autonomy) of the local agro ecosystems. From the recent changes to the environmental dynamics and its implications on the socioeconomic and cultural organization represented by fishers, crab catchers. Also the meaning of the environmental ethics on the agro ecosystems organization on the behavior of the social actors facing the exploitation of the fish resources (fish and crab) being an obstacle to the sustainable development. Field survey was carried out on the second semester of the year 2005 by the application of techniques such as direct observation by 52 semi-structured interviews with fishers, crab catchers and urban population from the village of Brejo Grande. The identification and characterization of the agro ecosystems from the estuary occurred by the application of the properties defined by Conway (1987) and Marten (1988). The regularization of the São Francisco river discharge from the construction of the electric power dams and also the recent introduction of shrimp projects have led to serious changes on the environment dynamic and consequently a reduction on the availability of fish and crab. This has brought dramatically impacts on the production and social organization, marginalizing traditional ways of natural resources use, socio-cultural diversity and the historical knowledge built by the local population. These facts create problems to the development of sustainable policies on the estuary. The behavior on the use of the natural resources can be identified in two different ways. The first one based on the traditional cartesian paradigm also mecanicist. On the other hand there is this ethical resistant behavior, based on the respect for nature, and the comprehension of interactions to the natural elements.

As campanhas de campo ocorreram no segundo semestre de 2005, ocasião em que foram desenvolvidas técnicas como a observação direta e a aplicação de 52 entrevistas semi-estruturadas envolvendo pescadores, catadores de caranguejo e a população urbana do município de Brejo Grande. A identificação e caracterização de agroecossistemas no estuário ocorreram com a aplicação das propriedades definidas por Conway (1987) e Marten (1988). A regularização da vazão do rio São Francisco diante da construção de barragens e a introdução recente de empreendimentos de carcinicultura têm promovido mudanças à dinâmica ambiental e ao estoque de pesca e de caranguejo-uçá que, por sua vez, tem contribuído com impactos à organização produtiva e social dos atores sociais do estuário, marginalizando as formas tradicionais de exploração dos recursos pesqueiros, a diversidade sócio-cultural e os conhecimentos construídos historicamente pela população local. Esses fatores estabelecem barreiras às políticas de desenvolvimento sustentável no estuário do rio São Francisco. A conduta em relação ao uso dos recursos naturais pode ser percebida em duas correntes distintas de pensamento, uma baseada no paradigma tradicional cartesiano e mecanicista e outra de cunho ético, que ainda resiste, fundamentada na hermenêutica, no respeito à natureza, na compreensão da interação dos elementos naturais e na importância às gerações atuais e futuras.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de SergipePós-Graduação em AgroecossistemasUFSBRAgroecossistemasSustentabilidadeEstuárioRio São FranciscoAgroecosystemsSustainabilityEstuarySão Francisco RiverCNPQ::CIENCIAS AGRARIAS::AGRONOMIASustentabilidade de agroecossistemas: um estudo de caso no estuário do rio São Franciscoinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFSinstname:Universidade Federal de Sergipe (UFS)instacron:UFSORIGINALCLEIDINILSON_JESUS_CUNHA.pdfapplication/pdf2965160https://ri.ufs.br/jspui/bitstream/riufs/6629/1/CLEIDINILSON_JESUS_CUNHA.pdf76cfa8b9370e9b88d21c86ba6b117e68MD51TEXTCLEIDINILSON_JESUS_CUNHA.pdf.txtCLEIDINILSON_JESUS_CUNHA.pdf.txtExtracted texttext/plain276855https://ri.ufs.br/jspui/bitstream/riufs/6629/2/CLEIDINILSON_JESUS_CUNHA.pdf.txt6f94cabea3fd3a6371bf3dc4b08a55e5MD52THUMBNAILCLEIDINILSON_JESUS_CUNHA.pdf.jpgCLEIDINILSON_JESUS_CUNHA.pdf.jpgGenerated Thumbnailimage/jpeg1325https://ri.ufs.br/jspui/bitstream/riufs/6629/3/CLEIDINILSON_JESUS_CUNHA.pdf.jpg188b42000f78924568b784a9d03d7062MD53riufs/66292017-11-24 21:05:39.824oai:ufs.br:riufs/6629Repositório InstitucionalPUBhttps://ri.ufs.br/oai/requestrepositorio@academico.ufs.bropendoar:2017-11-25T00:05:39Repositório Institucional da UFS - Universidade Federal de Sergipe (UFS)false
