摘要：When society appropriates territory and natural resources, it promotes significant modifications on landscapes culminating in a series of socioenvironmental issues. However, such consequences are more evident in urban areas due to disordered occupation in the most vulnerable environments generating impacts and emergent risks. This work aims to present geoenvironmental analysis as instrument of investigation of vulnerability and environmental risks in systems marked by urbanization. For that, Cocó river watershed, in metropolitan region of Fortaleza, was used as study case. Results showed the efficiency of this type of investigation, making possible to comprehend the spatial distribution of risks and identification of territories more susceptible to these problems. Key words: geoenvironmental analysis, environmental vulnerability, urban environment, environmental risks.
