Popis: Anthropic transformations, partly driven by human activity, have been causing disruptions in ecological patterns and processes within watersheds over the years, leading to landscape instability. Within this context, Hemeroby evaluates the intensity of alterations in landscape structure and function, classifying them based on their level of naturalness. Thus, the objective of this study is to analyze the landscape of the Turvo River Watershed in Barra do Turvo/SP according to Hemeroby levels. Vector files of vegetation cover and land uses from 1990, 2000, 2010, and 2020 were integrated using the ArcGIS Intersect tool with vector files of pedology, geology, geomorphology, relief amplitude, slope, climate, and erodibility. After combining the files, Hemeroby levels were classified to produce maps. The results of Hemeroby levels in the studied watershed ranged from Minimum (encompassing forest classes and water), with low technological and energy dependence for maintaining ecological functions, to Very High (covering the urban area of Barra do Turvo/SP), with high technological and energy dependence and low self-regulation capacity. The landscape of the investigated watershed exhibits a high level of human intervention due to agricultural practices, resulting in secondary vegetation and urban influence. Thus, the study of Hemeroby is important for evaluating negative impacts on the local ecosystem, thereby aiding in landscape planning and decision-making at municipal, state, and national levels.
