Análise multitemporal da dinâmica da paisagem para os municípios de Barroquinha e Chaval, Noroeste do estado do Ceará - Brasil, pelo uso e cobertura da terra

Abstract

The change in the landscape is caused by the natural processes resulting from the interaction of surface agents with the environment, where these dynamics can take up to thousands of years to occur, but when anthropic actions interact with the environment, landscape dynamics can occur in a way accelerated, modifying the landscape in short time span and covering large areas. The interventions that the man submits to the terrestrial surface can cause in negative effects against himself, generating impacts and risks of both financial damages and the own loss of lives. Sustainability actions are important for the balance between environment and man, but for this the organization of geographical space is important. For this, the present work has the objective of multitemporal analysis of the land use and land cover of the municipalities of Barroquinha and Chaval, in the State of Ceará, in a short time scale to identify the main processes and impacts of the man action in the landscape. This analysis was carried out by developing thematic maps in a scale of 1: 25,000 created through the processing of high resolution (RapidEye) images of 2012 and medium resolution (Landsat 8) of 2015 in a GIS environment. The data obtained allowed to identify and quantify the forms of use, especially the growth of urban areas that are invading areas of marine flooding, the growth of aquaculture activities in the fluvial plains besides the reduction of forest areas.
