Community-based geospatial multi-hazard analysis of the built heritage in Guaranda, Ecuador

[EN] Disaster risk reduction in heritage and culturally significant assets within the urban and rural parishes of Guaranda is a strategic priority for preserving cultural identity and strengthening community resilience. This study assesses the vulnerability of heritage buildings through a multidisciplinary approach that integrates local knowledge and promotes the active participation of key stakeholders. The applied methodology was structured into four phases: (i) preliminary analysis, (ii) inventory update, (iii) vulnerability assessment, and (iv) evaluation of the process and its social and impact in the community. Main results include the inventory update of 526 heritage buildings, achieving 99% coverage with updated data. Additionally, various traditional construction typologies were identified, and thematic maps were developed to represent vulnerability to seismic, flood, landslide, and volcanic hazards. Lastly, citizen participation was strengthened through the implementation of a satisfaction survey and the creation of the collective “Somos Memoria”.
