The overall objective of this study is to analyze the environmental vulnerability of the Jaurucu sub-basin and to understand how land cover and land use changes between 1990 and 2020 affect the loss of its landscape potential and its geoecological and socioeconomic features, including the pattern of encroachment of environmental systems. . , possibilities and limits of use and the impact on spatial changes. To achieve the desired goals, the theoretical and methodological foundations of the earth system approach, the theory of ecological dynamics, the concepts of landscape, land system and stability of the environmental system were chosen; The concepts of risk and vulnerability were introduced to avoid confusion when understanding these concepts. The research used techniques and methodological procedures as theoretical and methodological support for mapping environmental systems, assumptions by Bertrand (2004), Sotchava (1977), Tricart (1977), Monteiro (2000), Souza (2000) and others. The cartographic products were created with the support of geographic information systems (GIS). The environmental vulnerability analysis was adapted by applying the methodology of Crepani et al. proposed method. Persons. (2001), Grigio (2003), Tagliani (2003), Costa et al. (2006), Oliveira and Mattos (2014), based on Tricart (1977). Field work has been performed to verify the generation of land cover and land cover maps using MapaBiomas, vulnerability determinations are calculated using the grid calculation tool from algebraic equations crossing data in the GIS environment. Therefore, creating a sustainable development plan requires planning and analysis of the environment. Understanding vulnerable environments and the systems used within them helps with territory planning.
