Riparian vegetation or riparian forest maintains a direct relationship with water resources because it has several functions, among them, the maintenance of water quality. The objective of this research was to analyze the gaps between the permanent protection area, the riparian vegetation or riparian forest and water quality, contained in publications between 2012 and 2021, for the municipality of Paragominas, Paraense Amazon. The methodology used was inductive of quantitative and qualitative scope, and observational nature. The secondary data were obtained in electronic links, of free access, involved with the themes of this research. The literature selection occurred with the application of three selective descriptors: permanent protection area, riparian forest, and water resources, associated with water quality. The data obtained and analyzed indicated that, of the four literatures selected, the gaps found were related to: lack of analysis of water quality (n = 2; 50%); lack of suggestions for the problem encountered (n = 1; 25%). Therefore, research on vegetation/riparian forests is still analyzed without the context of environmental integration in terms of the ecosystem and environmental services provided both by these vegetations and for water bodies.
