Resultantes ambientais da drenagem de superfícies brejais e lacustres na baixada Campista, Norte do Estado do Rio de Janeiro, Brasil

Abstract

Interventions in river environments are measures taken by men since they have become sedentary. In the Campista lowland, the main objective of these interventions was to create the ideal conditions for the establishment of the sugar agro-industry and the expansion of sugarcane cultivation areas. To achieve this, a wide drainage of the wetland and lacustrine surfaces of the region was carried out through the deployment of a network of artificial channels. Currently, it is clear that these structures acted so that they intensified the consequences of environmental disasters deflagrated by floods and droughts. Given this context, this work presents a historic review of this drainage process, as well as assessment of the environmental consequences of such interventions, especially those regarding the hydrology of river environments that characterize the low courses of rivers, and the worsening of extreme hydrological events which eventually cause environmental disasters.
