Acompanhamento da implantaÃÃo das medidas mitigadoras propostas para a recuperaÃÃo das Ãreas degradadas na execuÃÃo dos aÃudes pÃblicos Aracoiaba e SÃtios Novos, no Estado do Cearà / MONITORING THE IMPLEMENTATION OF MEASURES FOR PROPOSALS MITIGATING RECOVERY OF DEGRADED AREAS IN IMPLEMENTATION OF PUBLIC AND NEW SITES ARACOIABA DAMS, IN CEARÃ

Fernanda Oliveira Cavalcante Demes 18 December 2013 (has links)
A exploraÃÃo de Ãreas de emprÃstimo para obtenÃÃo de materiais para obras civis tem resultado na degradaÃÃo ambiental, muitas vezes, com sÃrios impactos nos meio fÃsico e biÃtico. Assim, os impactos ambientais de Ãreas de emprÃstimo devem ser identificados, para que sejam propostas e executadas medidas visando à sua recuperaÃÃo. Neste trabalho, procurou-se avaliar a eficÃcia das medidas mitigadoras propostas nos estudos de impacto ambiental dos aÃudes pÃblicos Aracoiaba e SÃtios Novos, no estado do CearÃ, para a recuperaÃÃo das Ãreas degradadas durante a obtenÃÃo de matÃria prima para suas obras civis. A pesquisa teve inÃcio com o levantamento dos EIA/RIMA dos AÃudes PÃblicos Aracoiaba e SÃtios Novos, com Ãnfase na anÃlise dos impactos identificados como possÃveis de ocorrerem nas Ãreas de emprÃstimo dos dois empreendimentos. Foram tambÃm levantadas as medidas mitigadoras propostas para recuperaÃÃo das Ãreas de emprÃstimos dos dois reservatÃrios. A partir de pesquisas de campo foi realizado levantamento das medidas mitigadoras efetivamente implantadas para recuperaÃÃo das Ãreas de emprÃstimo. A pesquisa permitiu a realizaÃÃo de estudo comparativo entre as medidas propostas e as efetivamente implantadas nas Ãreas de emprÃstimo dos dois aÃudes. Constatou-se que vÃrias medidas propostas nÃo foram implantadas, principalmente nas Ãreas de emprÃstimo do AÃude SÃtios Novos, resultando na existÃncia de Ãreas ainda degradadas, necessitando de recuperaÃÃo. Ao final, propÃe-se a adoÃÃo de aÃÃes visando mitigar a degradaÃÃo ambiental resultante dos dois aÃudes, nas suas Ãreas de emprÃstimo. / Exploitation of borrow areas to obtain materials for civil works has resulted in environmental degradation , often with serious impacts on physical and biotic environment . Thus , the environmental impacts of borrow areas should be identified , to be proposed and implemented measures aimed at their recovery . In this study, we sought to assess the effectiveness of mitigation measures proposed in the environmental impact studies and public dams Aracoiaba Novos , in the state of Cearà , for the recovery of degraded areas for obtaining feedstock for its civil works . The research began with a survey of the EIS / EIR for Public and Sites New Dams Aracoiaba , with emphasis on the analysis of the impacts identified as possible to occur in the areas of loan of two developments . Were also raised proposals for the rehabilitation of the two reservoirs loans mitigation measures . From field research was conducted survey of mitigation measures effectively implemented for the rehabilitation of loan. The survey allowed for a comparative study between the proposed measures and effectively implemented in the areas of borrowing of the two dams . It was observed that several proposed measures were not implemented , mainly in the areas of loan Novos Dam, resulting in the existence of yet degraded areas needing recovery . At the end, we propose the adoption of actions to mitigate environmental degradation resulting from the two dams in their lending areas.
