Impactos ambientais no médio curso do Rio Curu

Abstract

From a historical perspective, human beings have a tendency to occupy regions near rivers, because in these fluvial channels they find sufficient water supply for survival. Civilizations all over the world have developed along the margins of important rivers throughout history, as for example the Mesopotamians, inhabiting the regions near the Tigris and Euphrates rivers. Other cities in various parts of the world have also developed in this way, until we get to the local context, in which some cities in the State of Ceará emerged along the margins of important rivers, among them the Curu River. The spatial cut out is situated in the middle course of the mentioned river, located in the Mesoregion of the North of Ceará, having important population densities such as the urban perimeters of Apuiarés, General Sampaio, Pentecoste and São Luís do Curu, which are located near the riverbed and have direct influence on the hydric body. The theme related to "obtain and analyze the indicators of environmental impacts, as well as understand the repercussions in population densification near the banks of the middle course of the Curu River", was chosen through the understanding of the importance of preserving the main river course of the region, since basic sanitation policies are lacking and some anthropic actions cause serious consequences, affecting the entire population and local productive chain. Mentioning the recently sanctioned Sanitation Regulatory Framework, this paper exposes some of its commitments, as well as the importance of fulfilling these actions to mitigate the effects caused by the neglect of public power over the years, such as the lack of total coverage of sewage, garbage collection, water supply and the lack of social awareness of the inhabitants of the region in relation to environmental preservation. Through bibliographic reviews in works already done on the subject and in the study area, by means of statistical data from public agencies of the State, a series of impacts caused by the absence of the above-mentioned policies on the health of the population was verified, causing silting, intensifying the water deficit in an intermittent river and causing diseases to the local population. At the end of this work, proposals will be presented for certain policies that can be adopted by the competent authorities, in order to reduce the damage caused long ago to the important Curu River.
