This report presents a comprehensive, citizen-generated assessment of disaster and pollution risks in the municipality of Kakanj, one of the most environmentally burdened areas in Bosnia and Herzegovina. Based on participatory mapping conducted between June 2025 and January 2026, 127 citizen scientists documented 197 disaster risk and pollution sites, covering geological, hydrological, meteorological, climatological, biological, chemical, transport-related, and structural risks, as well as deforestation. The findings show that while Kakanj faces multiple, interconnected hazards, chemical risks emerge as the most severe, persistent, and system-wide threat, acting as a multiplier that exacerbates nearly all other risk categories.
