Inventário ambiental de paleodunas fluviais em Sento Sé, Bahia

Abstract

This dissertation focused on the processes of origin and current conditions of the paleodune fields located along the banks of the São Francisco River in the municipality of Sento Sé, Bahia. These sandy features provide significant evidence for understanding the effects of paleoclimatic elements and factors on these areas, which are essential for comprehending the genesis and evolution of these environments over the course of historical time. In this sense, the objective of the research was to analyze the fluvial paleodune fields, their processes of origin, and the natural and anthropogenic impacts on the environmental system. This is applied research with a qualitative-quantitative approach, involving exploratory, bibliographic, documentary, and field studies. The theoretical framework of the research was developed based on a systematic literature review (SLR), grounded in a dialectical and systemic approach and informed by theories of landscape ecodynamics, geosystem-territory-landscape, fieldwork, and rapid survey. The research findings identified the processes that gave rise to the paleodunes, their evolution, the phytophysiognomy of the landscape, the categorization of the landscape into ecodynamic units, current conditions regarding natural and anthropogenic impacts, and the need for the implementation of management and environmental conservation plans for these paleoenvironments.
