Impactos ambientais decorrentes das atividades da carcinicultura ao longo do litoral cearense, nordeste do Brasil

Abstract

The activities of shrimp production in ponds in the State of Ceará, northeast of Brazil, were analyzed from the point of the view of the integration of energy flows. We emphasized the environmental relationships with the tides dynamics, the contribution of sediments to the coastal zone and the evolution of the geoenvironmental units. We analyzed the importance of the mangroves ecosystem in the production, consumption and distribution of nutrients to the coastal zone and the environmental impacts caused by shrimp farming. We noticed that this kind of industrial activity took into account only the market costs without considering the environmental, ecological, social, and cultural and biodiversity harms. At the end, we proposed an integrated action model for the appropriate use and management of the natural resources of the estuarine system.
