Mapa de risco: uma elaboração a partir da percepção comunitária das áreas suscetíveis a inundações e alagamentos na microbacia do Rio Cereja, Bragança/PA

Abstract

The increase in socially unequal urbanization is producing a movement of mobility among the poorest populations towards risk areas and conservation units, due to the elevated level of real estate speculation in city centers. This work will study environmental risk in the Cereja River watershed in Bragança, Pará, Brazil. The Cereja River is an important watershed, which flows into the Caeté River drainage basin, still within the municipality. However, this water resource has become increasingly precarious and depreciated, since the settlements on its banks have neglected maintenance and lack basic sanitation. As a result, there has been increasing investment in the development of hydrological models with the aim of predicting impacts that could cause inconvenience to the population. This study aims to characterize areas of flooding and inundation, as well as areas of critical slope to mass movements, identifying and classifying the risks related to these through a questionnaire applied to the population living in the area, evaluating the areas in terms of socio-environmental risks along the Cereja River.
