Data on perception of the implementation and effectiveness of local dry-gas degassing measures in the Goma area (East DRC) Blaise Mafuko-Nyandwi https://doi.org/10.5281/zenodo.17628103

Editorial statement
This study offers integrated socio-spatial assessments of the mitigation of diffuse carbon dioxide degassing risk associated with Mazuku. The paper reveals how locally developed practices shape household perceptions of safety in Goma’s volcanic environment. The analysis advances community-centred, co-created risk governance for diffuse volcanic gas hazards. These findings provide a novel Global South perspective that bridges social perception with hazard monitoring, informing more inclusive and context-responsive strategies for managing persistent volcanic CO₂ risks.
Short summary
This paper studies how households in Goma (Eastern Democratic Republic of the Congo) respond to mazuku – invisible, odourless carbon dioxide gas that accumulates in depressions. Surveys and interviews show that resource-intensive measures are adopted only by those who can afford them, while awareness measures are valued by all. The findings highlight that involving communities in designing risk mitigation that match their economic realities is essential.
