Geomorphology of Brazil: Complexity, Interscale and Landscape: XIII SINAGEO (National Symposium of Geomorphology)

Description

This book presents the most relevant articles selected from the annals of the symposium. In the last few years, Brazilian Geomorphology has experienced a series of epistemological and methodological innovations expressed by the incorporation of the complexity paradigm, by the progressive break with the climate paradigm, by the emergency role of new theories, and by the advances in methodological fields favored by the adherence to geochronological techniques and in function of the increasingly widespread use of geotechnologies. Furthermore, the Anthropocene/Technogene emerge claims to be more than only a temporal cuts, but as conceptions of a science engaged with social and environmental issues. The National Symposium of Geomorphology, in the maturity of its 13th edition, constitutes a portrait and an important sample of Brazilian geomorphological production, aggregating works carried out in the most diverse types of landscapes of Brazil. The book provides an overview of the current scientific production of Brazilian Geomorphology, highlighting the diversity of landscapes and geoheritage in Brazil, the complexity of the morphogenetic and morphodynamic processes responsible for shaping its surface, and the various abundant methodologies used in geomorphological studies in tropical areas.
