Multidimensional assessment of sustainability extractivism of mangrove oyster Crassostrea spp. in the estuary of Cananéia, São Paulo, Brazil

Abstract

This study was carried out with groups of extractivists of mangrove oysters in the estuary of Cananéia, São Paulo State, Brazil, between the years 1999 and 2007 with the objective to evaluate and compare trends in the sustainability of this activity, in a multidimensional and integrated way, in social, economic, ecological, technological and ethical dimensions, using the method RAPFISH. The different groups had distinct trends related to sustainability and the social, technological and ethical dimensions had more influence on trends in sustainability than the ecological and economic dimensions. The group with the best performance in the sustainability assessment was Mandira, due to advances promoted by local social organization. On the other hand, the Porto Cubatão group showed the worst performance, once this is very recent group in the extractivism of oysters. The RAPFISH proved to be a useful tool for data assessment.Keywords: sustainability, Crassostrea spp., mangrove oyster, extractivism, fishery. Avaliação Multidimensional de sustentabilidade do extrativismo da ostra de mangue Crassostrea spp. no estuário de Cananéia, São Paulo, BrasilResumo O presente trabalho foi desenvolvido junto aos grupos de extrativistas de ostra em Cananéia, SP, entre os anos de 1999 e 2007 e teve o objetivo de avaliar e comparar as tendências relativas à sustentabilidade dessa atividade, de forma multidimensional e integrada, nas dimensões social, econômica, ecológica, tecnológica e ética, utilizando o método RAPFISH. Os diferentes grupos estudados apresentaram dististas tendências relativas à sustentabilidade e as dimensões social, tecnológica e ética exerceram maior influência sobre as tendências da sustentabilidade, do que as dimensões ecológica e econômica. O grupo com melhor desempenho na avaliação de sustentabilidade foi o do Mandira, em razão dos avanços promovidos pela organização social local, no extremo oposto posicionou-se o grupo do Porto Cubatão, em razão do grupo ser muito recente no extrativismo de ostras. O Rapfish se mostrou uma ferramenta útil no equacionamento dos dados.Palavras-chave: sustentabilidade, Crassostrea spp., ostra de mangue, extrativismo, pesca.

Adaptive Capacity Level Shapes Social Vulnerability to Climate Change of Fishing Communities in the South Brazil Bight

“…Therefore, the community with the highest adaptive capacity was Mandira. The high adaptive capacity of the community was driven by well-established community organization, proper management of the oyster resulting from a partnership between government, university and local knowledge (Machado et al, 2015), control of commercialization through a community cooperative (Kefalás, 2016), and the search for local income alternatives such as handcrafts and community-based tourism. On the other hand, Pontal de Leste had the lowest adaptive capacity, mainly due to its high dependence on fishing, inability to negotiate fish price due to its distance to the market and lack of electricity to freeze and store the fish, and absence of livelihood alternatives not related to fishing.…”

Sustainability indicators for evaluation of municipal urban water management system: the case of Volta Redonda – RJ/Brazil

“…The options of sustainability dimensions were presented according to literature: Environmental/ Ecological, Economic, Social/Cultural, Technological, Ethical and Political/Institutional. The degrees of importance were divided into: Very Important, Important, Less Important, Irrelevant and Not Sure (UN, 2007;Nascimento, 2012;Cruz & Ferrer, 2015;Machado et al, 2015;Hake et al, 2016;Silvestre, 2016;Spiller, 2016;Rantala et al, 2018).…”

Penilaian Keberlanjutan Sistem Usaha Kentang dengan Kriteria Multidimensi: Studi Kasus di Dataran Tinggi Dieng, Wonosobo

“…Metode Rapfish telah digunakan oleh banyak penelitian untuk menilai keberlanjutan antara lain oleh Ali (2015) yang menggunakan Rapfish untuk menganalisis status keberlanjutan multidimensi perikanan tangkap di Teluk Bone dan Nurmalina (2008) yang menggunakan Rapfish untuk menganalisis indeks dan status keberlanjutan sistem ketersediaan beras di beberapa wilayah di Indonesia. Rapfish juga digunakan dalam penelitian yang dilakukan oleh Machado et al (2015), penelitian tersebut berhasil membuktikan bahwa Rapfish merupakan alat yang tepat untuk menyajikan data keberlanjutan pada berbagai kelompok obyek penelitian. Rapfish juga dinilai sebagai metode analisis yang mampu mendukung suatu penelitian untuk menghasilkan bahan dan informasi secara cepat, akurat, dan aplikatif sehingga rekomendasi kebijakan yang dihasilkan dapat menjadi salah satu faktor penentu keberhasilan tercapainya pembangunan (Hartono et al 2005).…”
