A Framework for Fire Risk Assessment in Heritage Cities through Multi-Stakeholder Data Integration

Urban fire risk in heritage cities threatens lives, livelihoods, and irreplaceable historical monuments. Nepal's heritage cities, rich in cultural landmarks, face acute vulnerability due to dense settlement patterns driven by uncontrolled urbanization. Fragmented data availability prevents stakeholders from implementing effective fire risk mitigation measures at the community level, which intensifies the existing vulnerabilities. In this study, we address this challenge by developing comprehensive data through collaborative public-private partnerships involving multiple stakeholder experts. We propose scalable interventions designed to reduce fire risk while strengthening community resilience in ways that align with heritage preservation objectives. This integrated approach ensures that safety measures protect both people and the cultural assets that define these historic urban centers.

Our study area is Bhaktapur Municipality, a UNESCO World Heritage site rich with traditional wooden architecture. Our approach combines municipal planning data, private building inventories, community knowledge, and emergency response databases for fire hazards. We integrate Analytical Hierarchy Process (AHP) with GIS technology across three domains: hazard factors, vulnerability indicators, and response capacity. We establish public-private partnerships to gain access to previously prepared fire incident datasets while we protect commercial interests. We establish multi-stakeholder data protocols and develop community-centered collection mechanisms that respect local knowledge systems. We leverage real field knowledge from community-level surveys to assess the present scenario and propose upgrades to current practices. We perform dynamic vulnerability assessments that support both emergency planning and heritage conservation. Through weighted overlay analysis, we determine optimized fire hydrant placement for narrow streets that existing firefighting services cannot access. This spatial analysis ensures that infrastructure improvements respect the historic urban fabric while they enhance emergency response capabilities.

We expect collaborative data partnerships to enhance decision-making through three key contributions: (i) bridge critical information gaps that have long hindered effective fire risk management, (ii) support sustainable development, cultural preservation, and community resilience as interconnected goals and (iii) offer scalable lessons for complex urban management challenges in resource-constrained environments. This integrated framework demonstrates how heritage cities can balance safety imperatives with conservation priorities through evidence-based interventions.
