Abstract

The aim of this work is to analyze landscape-shaping processes in the Pampean plain, eastern sector of the Buenos Aires province, reconstructing the geomorphic evolution from the Late Pleistocene to the Anthropocene. For this purpose, a geomorphological analysis was carried out through the use of satellite images, topographic maps and field work. In this study, natural and anthropogenic processes are addressed in an integrative manner, considering both temporal and spatial scales. The geomorphic characteristics show the preponderance of coastal and aeolian processes over other exogenous processes. The emergence of two littoral barriers, the Samborombón Barrier (SB) and the Easter Sandy Barrier (ESB), has significantly influenced regional geomorphology, showing evidence of Quaternary sea-level fluctuations. Over time, human settlements were strategically located on elevated landforms of the Pampean plain, rich in resources. Since the late 19th century, human activity has rapidly transformed the landscape, especially altering the hydric system, marshes, beaches, dunes and littoral ridges. These processes also generated human-created landforms, such as channels, quarries, alluvial fans, among others. This study provides a regional context for future research, fostering the formulation of hypotheses to better comprehend the evolving dynamics of these environments.

期刊介绍： Anthropocene is an interdisciplinary journal that publishes peer-reviewed works addressing the nature, scale, and extent of interactions that people have with Earth processes and systems. The scope of the journal includes the significance of human activities in altering Earth’s landscapes, oceans, the atmosphere, cryosphere, and ecosystems over a range of time and space scales - from global phenomena over geologic eras to single isolated events - including the linkages, couplings, and feedbacks among physical, chemical, and biological components of Earth systems. The journal also addresses how such alterations can have profound effects on, and implications for, human society. As the scale and pace of human interactions with Earth systems have intensified in recent decades, understanding human-induced alterations in the past and present is critical to our ability to anticipate, mitigate, and adapt to changes in the future. The journal aims to provide a venue to focus research findings, discussions, and debates toward advancing predictive understanding of human interactions with Earth systems - one of the grand challenges of our time.
