Análise dos impactos ambientais no médio e baixo Jaguaribe a partir da memória histórica da ocupação humana e registros geológicos

Abstract

The Jaguaribe river is located in the East region of the Ceará State and represents the greater and more relevant hydric reserve of the State. Together with its more important tributaries, the Banabuiú and Salgado rivers, form the basins of the High, Medium and Low Jaguaribe. The enclosed area for its hydrographic basin comprehends approximately 80,000 km2, practically the half of the area of the State. Although the hydric irregularity of the rivers in Ceará, the Jaguaribe river had an important role in the occupation and economic development of the State. From a historical approach, since the beginning of its colonization in the seventeenth century to the present day, together with the natural elements, linked to the various uses and the various economic activities in the area, sought to present and analyze the various impacts of this occupation in the Middle and Lower basin Jaguaribe, also in face of the Project of the New Forestry Code approved by the Senate in December of 2011, this research presents the importance of the evaluation of the environmental impacts in a integrated and systematic way, taking in consideration the eventual residual and/or cumulative environmental impacts generated separately or for the addition of all the activities developed in the region, in order to prevail the rational and sustainable use of the environment for the future generations. This research has exclusively qualitative characteristics, with the technical procedures, literature and documentary research, and the data collection, the simple observation, interviews, and photographic survey. As theoretical framework, among the numerous works used are: Girão, R. (1985, 1986 and 2000), Studart B.D. (1896, 1898) and Theberge (1895, 1973). Regarding the conclusion of this process of scientific research, one can consider that, historically, the occupation of the Jaguaribe river was taking into account the interests solely anthropogenic.
