PurposeThis paper aims to provide a deep understanding of rural household livelihoods in the Mekong Delta and to explore how they can cope with climate stressors at the ground level.Design/methodology/approachThe paper employs the sustainable livelihood framework at a household and also an individual scale. The general data obtained from a survey of 2,100 households provide an overview of their livelihoods. Qualitative and quantitative methods were adopted, as case studies, to comprehensively assess 100 households in one commune affected by annual floods and an additional 100 households in another commune affected by sea level rises. Livelihood profile analysis is beneficial to identify specific livelihood change patterns that have taken place in these specific cases.FindingsThere are four types of livelihood adaptation to climate stressors: (1) change of structure of agricultural systems, (2) change of employment locations, (3) resettlement with strong impact on livelihoods and (4) out-migration. The household livelihood resources and the local economic structures have significant roles in driving adaptive solutions.Research limitations/implicationsThis paper provides detailed profiles of the livelihood change considered as passive adaptation of smallholders in the Mekong Delta.Originality/valueIt contributes to the knowledge of rural households in multiple aspects with regard to how they cope with climate change via reflection on their livelihoods.
