No. of bitstreams: 1 Alisson Lima Disserta??o.pdf: 5677317 bytes, checksum: 0115ba11e6fb05ac3437a37fa5d1c426 (MD5) Previous issue date: 2018-02-27 Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES For the first time in Chapada Diamantina, a group of prospectors have organized to facilitate the continuity of the prospecting and mining of diamonds, established in 2001 the Prospectors' Cooperative of Andara? (COOGAN). COOGAN, who obtained authorization for the realization of mineral inquiry in the area between 2006 - 2013, is responsible for the environmental recovery of the degraded area of current mines, presenting a new formalized perspective of the exploitation of the alluvia diamantiferous, in the areas known as Santa Rita and Pau D'?leo. The most recent cycle of the mines of this region uses semi-mechanized techniques for sterile removal of sediments and for dredging of the layer of diamantiferous gravel. As any human action, this type of mining causes impacts to the environment, being able to contribute directly to environmental degradation, with emphasis to the destruction and / or alteration of vegetation, physio-chemical characteristics of the solo and water bodies in the adjacent mines, interfering with river courses and drainage standards. In this context, the minimization of the impacts of the exploited manual extration on the environment and the necessity of recovery of the degraded areas are key points for conflict resolution due to the mining prospects of diamonds that at present takes place in the vicinity of the Paragua?u river, in the municipality of Andara?. This research characterizes the alluvial deposits goal of mining prospects, characterized by the current forms of mining of the prospectors identifying its environmental impacts and contributing with proposals for formalizing and environmental adaptation of the small and middle miners through cooperatives and ratifying the importance of public policies that help the mine to support itself in accordance with environmental legislation. For this reason, this study will carry out an evaluation of the progressive rehabilitation of areas that were already recovered by the cooperative, noticing if the recuperation reached the standards recommended by the Brazilian mineral and environmental legislation and proposing a model of sustainable plowing. Este trabalho avaliou o processo de recupera??o ambiental de uma ?rea impactada por a??o garimpeira em um dep?sito aluvionar de diamante no munic?pio de Andara? na Chapada Diamantina, Bahia. Pela primeira vez na regi?o, um grupo de garimpeiros se organizou para viabilizar a continuidade da pesquisa e lavra de diamantes, fundando em 2001 a Cooperativa de Garimpeiros de Andara? (COOGAN). A COOGAN, que obteve autoriza??o para realiza??o de pesquisa mineral na ?rea entre 2006 ? 2013, ? respons?vel pela recupera??o ambiental da ?rea degrada dos atuais garimpos e tenta apresentar uma nova perspectiva formalizada e sustent?vel da explora??o de recursos minerais. O ciclo mais recente dos garimpos na Chapada utiliza t?cnicas semimecanizadas para remo??o dos sedimentos est?ril e para dragagem da camada de cascalho diamant?fero. Como toda a??o humana, este tipo de minera??o causa impactos ao meio ambiente, podendo contribuir de forma direta para a degrada??o ambiental, com ?nfase para a destrui??o e/ou altera??o da vegeta??o, das caracter?sticas f?sico-qu?micas dos solos e corpos d??gua nas adjac?ncias do garimpo, interferindo nos cursos d??gua e padr?es de drenagem. Nesse contexto, a minimiza??o dos impactos da explora??o garimpeira sobre o meio ambiente s?o pontos fundamentais para a continuidade da lavra garimpeira de diamantes na regi?o. Este trabalho contribui com propostas para a formaliza??o e adequa??o ambiental do pequeno e m?dio minerador atrav?s de cooperativas e ratifica a import?ncia de pol?ticas p?blicas que ajudam o garimpo a se manter em conformidade com a legisla??o ambiental. Adicionalmente, este estudo realizou uma avalia??o da reabilita??o progressiva de ?reas testes que j? foram recuperadas pela cooperativa, observando se a recupera??o atingiu os padr?es recomendados pela legisla??o mineral e ambiental brasileira e prop?s um modelo de lavra sustent?vel. |
