Climate change vulnerability and poverty nexus: evidence from coastal communities in central Vietnam

The vulnerability assessment of small-scale households on the central coast of Vietnam has been inadequate despite the apparent impacts of climate change. This knowledge gap presents challenges for identifying at-risk individuals and communities and could impede effective public policy and resource allocation for adaptation efforts. To address this issue, this study employed the Livelihood Vulnerability Index referencing IPCC definitions (LVI-IPCC) framework to examine livelihood vulnerability and its determinants among 455 small-scale households in the coastal areas of Phu Vang district, Thua Thien Hue province, Vietnam. The LVI-IPCC calculation utilized a database of 11 major and 33 sub-indicators collected through a household survey conducted in 2021. The findings revealed that these households exhibit moderate vulnerability to natural disasters and climate shocks, as reflected by their high sensitivity index scores. Additionally, the study identified a persistent cycle of poverty and livelihood vulnerability among coastal communities, wherein poverty and reliance on nature-based income serve as the root cause of the exposure and a gateway to this loop. This study strongly advocates for a pro-poor approach that places poverty alleviation at the forefront of community development planning and climate change agendas. Under this approach, developing value chain models in agriculture and aquaculture and diversifying livelihoods through activities such as community-based tourism is highly recommended.
