“…As pointed out by Tundisi et al (2014) the Amazon watersheds and rivers harbours a mega diversity of terrestrial and aquatic plants and animals. Mechanisms that maintain this biodiversity are the fluvial dynamics and the intense gene flux due to water level fluctuations and the interaction of climatological, hydrological, geomorphological and biological components of the system.…”

“…Land cover, land use studies and its changes will provide insights into the new patterns of occupation of the landscape, and its future perspectives. To summarize, the installation of a "observatory" before and during the construction of the reservoir will be an important conceptual development in the work of a EIA (Tundisi et al, 2008(Tundisi et al, , 2014.…”

The Environmental Impact Assessment of reservoir construction can be viewed as a new strategic perspective for the economic development of a region. Based on the principles of a watershed approach a interdisciplinary and multidisciplinary systemic view including biogeophysiographical, economic and socio environmental studies the new vision of a EIA provides a basic substratum for the restoration economy and an advanced model for the true development much well ahead of the modernization aspects of the project of a reservoir construction.Keywords: watersheds, reservoirs, development, restoration economy. Avaliação de Impacto Ambiental da construção de reservatórios: novas perspectivas para a economia da restauração e desenvolvimento, regional: o estudo de caso Belo Monte (UHE) ResumoA Avaliação de Impacto Ambiental (AIA) de reservatórios em construção deve ser considerada como uma nova perspectiva estratégica para o desenvolvimento regional muito mais avançada do que a modernização produzida pela infraestrutura. Baseada no princípio de abordagem sistêmica, interdisciplinar e multidisciplinar incluindo a base biogeofisiográfica, e estudo sócio ambientais, a nova visão da AIA promove um substrato básico para a economia da restauração e para um nível avançado de desenvolvimento muito além do mero processo de modernização produzido pela construção do reservatório. Estas mudanças de paradigma conceitual em governança, economia e sustentabilidade são fundamentais para o desenvolvimento avançado do país.Palavras-chave: bacia hidrográfica, reservatórios, desenvolvimento, economia da restauração.

“…Therefore, they jeopardize the biodiversity and the functioning of these ecosystems, which make the aquatic life susceptible to irreversible losses (Janse et al, 2015;Zimmermann et al, 2008;Zhang, 2007). Hence, it is crucial to protect those regions to maintain their ecological services and functions (Tundisi et al, 2014).…”

Bacanga River Basin faces environmental problems related to urbanization and discharge of untreated domestic sewage, which compromise its ecosystem health. Due to the small number of studies that assessed its water quality, the present study aimed to assess the current status of this ecosystem based on the aquatic life protection index. Samples were carried out every two months, in a total of six events, in six sites along the basin, where the water samples were collected to assess physicochemical parameters and calculate the trophic state index and the index of minimum parameters for the protection of aquatic communities. The data were also compared with values determined by the resolution National Environment Council -CONAMA 357/05. Our results reveal significant changes in the water quality of Bacanga River Basin. An increase in nutrients and chlorophyll-a concentration led it to eutrophication. The surfactant values were high and put in danger the aquatic biota. Dissolved oxygen rates were below the values allowed by the resolution in most sites sampled. The current water quality is terrible for the protection of aquatic life in 61.92% of the sites sampled.Keywords: water quality, contamination, domestic sewage. Índice de proteção da vida aquática em uma bacia urbana do rio Bacanga no norte do Brasil, São Luís -MA ResumoA Bacia Hidrográfica do rio Bacanga (BHRB) apresenta problemas ambientais relacionados a urbanização e lançamentos de esgoto in natura que comprometem a qualidade desse ecossistema. Devido ao reduzido número de estudos associados à avaliação da qualidade da água no local, este estudo teve como objetivo avaliar a situação atual desse ecossistema por meio do Índice de Proteção da Vida Aquática. Seis amostragens bimestrais foram realizadas em seis pontos ao longo da bacia, coletando parâmetros físico-químicos para a aplicação do Índice de Estado Trófico e Índice de Parâmetros Mínimos para a Proteção da Vida Aquática, relacionando-os com a resolução Conselho Nacional do Meio Ambiente -CONAMA/357. Os resultados revelaram alterações significativas na qualidade da água da BHRB, o aumento de nutrientes e das concentrações de clorofila-a conduziram ao um estado geral de eutrofização. Os valores de surfactantes foram altos colocando em risco a biota aquática e as taxas de oxigênio dissolvido estiveram abaixo do permitido pela resolução na maioria dos pontos amostrados. A situação atual da qualidade da água para proteção da vida aquática é péssima em 61,92% dos pontos amostrados.Palavras-chave: qualidade da água, contaminação, efluentes domésticos.
