In the midst of increasing global uncertainties, understanding household vulnerability to disaster risks and identifying the most susceptible individuals and communities has become an urgent concern. This study assesses and compares the flood vulnerability of two communities, Quang Tho and Quang Phuoc, in Thua Thien Hue Province, Vietnam. The study utilizes primary data collected in 2022 from 280 rural households whose livelihood sources are agriculture and fishery. Flood vulnerability is determined by applying the Livelihood Vulnerability Index based on the Intergovernmental Panel on Climate Change's definition (LVI-IPCC) approach. Our analysis reveals that both communities exhibit moderate vulnerability to flood hazards across various dimensions. Notably, fishing-only communities are found to be more vulnerable to flooding compared to mixed agri-fishery farmers. Additionally, we have identified several factors that exacerbate vulnerability, including poverty, low education levels, single parenthood, limited resources, narrow livelihood strategies, and inadequate social connections. Therefore, development policies and disaster risk reduction programs should prioritize disadvantaged groups, focusing on promoting social inclusion and gender equality in accessing services and public resources. It is concluded that tailored disaster risk management and rural livelihood development initiatives are crucial to addressing each community's specific vulnerabilities and challenges, fostering resilience, and thus reducing future risks. Achieving greater sustainability and equilibrium for vulnerable groups necessitates continuous action and investment.
