Prioritization of Risk Factors in Sea-Island Tourism: A Study in Quang Ngai Province, Vietnam

The prioritization of risks associated with sea-island tourism activities in Quang Ngai Province, Vietnam, was conducted through a structured multi-criteria decision-making (MCDM) framework.An integrated methodology combining the Analytic Hierarchy Process (AHP) and Pareto analysis was employed to systematically identify and rank critical risk factors.Risk criteria were initially identified through expert consultations involving professionals with extensive experience in sea-island tourism and destination management.These criteria were then evaluated using the AHP method to determine their respective overall weights.Subsequently, Pareto analysis was applied to classify the most impactful risk categories requiring immediate attention.The findings indicate that the top four priority risks include accidents, damages caused by natural disasters and extreme weather events, outbreaks of infectious diseases, and broader implications of climate change.These risks exhibited overall weight values ranging from 0.1061 to 0.3315, underscoring their dominant influence on tourism sustainability and safety.This prioritization offers essential insights for policymakers, destination managers, and tourism planners in the formulation of effective risk mitigation strategies.The integrated AHP-Pareto approach demonstrated in this study contributes a replicable model for the proactive management of tourism risks in coastal and island contexts, where ecological sensitivity and visitor safety are of heightened concern.
