The Tinguá Biological Reserve (TBR), a full protection conservation protected area in the municipalities of Nova Iguaçu, Duque de Caxias, Miguel Pereira, and Petrópolis (Rio de Janeiro, Brazil), was historically established to protect water sources that have supplied part of the Rio de Janeiro metropolitan region since the imperial period. However, the rivers protected by this unit face degradation challenges in urban areas, where pollution and inequalities in water access highlight socio-environmental conflicts. This study proposes environmental education practices combined with popular communication, anchored in the concept of the hydrosocial cycle, which integrates the natural, political, and cultural dimensions of water. Using these tools, it becomes possible to convey more effectively to the community the importance of the water’s journey—from its natural cycle to the social sphere, where it undergoes anthropogenic changes. This approach emphasizes the social dynamics of water and underscores the role of TRB in preserving these rivers. The hydrosocial cycle concept stresses the need for a critical understanding of water, which cannot be reduced to its physical availability or distribution techniques but must be analyzed within the broader context of social relations and power structures. The methodology combines exploratory, documentary, and theoretical analysis with participatory action research, including participant observation through the author’s perspective, who is directly involved in the reserve’s socio-environmental initiatives. In addition to the analysis, pedagogical workshops were conducted in three local schools. These activities demonstrated that environmental education, by linking biodiversity conservation and social rights, also strengthens citizenship, revealing water as a vital element connecting nature and society. Popular communication emerged as an empowerment tool, fostering dialogue with the community.
