The Tarumã-Açu River Basin is a strategic area for public policies related to water resource management in Amazonas. The study aimed to survey the eco-environmental vulnerability (natural and environmental) and propose environmental zones for the basin. The physical (soils, geology, relief vulnerability, rainfall-erosion) and anthropic aspects (land use and cover) were characterized and systematically analyzed using the methodology for land vulnerability to soil loss. The mapping data were submitted to the Analytic Hierarchy Process (AHP) and integrated using Map Algebra. Environmental vulnerability was associated with the limits of legally protected areas and planning purposes in the basin, such as Environmental Protection Areas (APA), Forest Reserves, and Settlement Projects, resulting in the following environmental zones: Priority Preservation; Development; Sustainable Use; Preservation/Recovery; and Recovery. The mapping of natural and environmental vulnerability indicates the predominance of medium-vulnerability environments, concentrated in the lower and upper sectors of the basin. Environmental zones can provide conservation and recovery strategies based on the impacts of natural and anthropogenic disturbances, aiming to protect water resources, which are essential for planning actions and sustainable use in the basin.
