Purpose: This 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/approach: The 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.Findings: There 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/implications: This paper provides detailed profiles of the livelihood change considered as passive adaptation of smallholders in the Mekong Delta.Originality/value: It contributes to the knowledge of rural households in multiple aspects with regard to how they cope with climate change via reflection on their livelihoods.

This study explores the perceived walkability of one-way commercial streets by utilizing immersive 360-degree virtual reality (VR) videos. While one-way roads are often introduced to facilitate smooth traffic flow on narrow roads, providing safe and walkable environments for pedestrians on the one-way roads is crucial, especially in commercial areas with heavy pedestrian traffic. We recruited 40 students to assess the perceived walkability of one-way roads based on ten VR scenarios. For each scenario, variables such as road width, one-way traffic status, vehicle approach direction, and the presence of sidewalks were configured differently. This study found that while there is awareness of one-way road types, the presence of sidewalks is considered critical factor contributing to enhanced perceived walkability on narrow commercial street. In the condition of narrow road width, one-way roads are the only applicable road layout to have a sidewalk, implying the potential of one-way roads for better walkability. Besides, the study also revealed the high correlation between five dimensions of perceived walkability, emphasizing their role to enhance perceived walkability in a setting of one-way roads. This study’s findings could be utilized for more systematic walkability assessments and urban design improvements, especially in constrained road spaces.

As climate change increasingly interacts with socioeconomic development factors to contribute to migration, understanding how climate and migration can coalesce to exacerbate health risks is urgent. Our study examines how migration influences the health of Mekong Delta migrants in Ho Chi Minh City and explores the role of weather and climate variability in the migration experience and health status of migrants before and after migration. Using a qualitative approach, we conducted 43 in-depth semi-structured interviews. We found migration is a strategy to cope with livelihood insecurity in the Mekong Delta. Livelihood trade-offs in Ho Chi Minh City produce precarious living and working conditions contributing to changes in the self-reported health status of migrants after migration, while climate variability is a threat multiplier for migrants’ health and livelihoods in both the Mekong Delta region and Ho Chi Minh City. Our findings illustrate the intersections of climate, migration and health where migrants make strategic health trade-offs to pursue better livelihoods, whilst weather and climate variability exacerbate the health risks and livelihood insecurity of migrants. This study supports the need to implement policies that reduce trade-offs, strengthen migrants’ adaptive capacity, and address underlying socioeconomic and political factors shaping vulnerability across the rural-urban continuum.

Although many researchers and policy makers have argued that social mixing could contribute to sustainable communities, most people still prefer to live in a homogeneous rather than a diverse community. Considering the large gap between the political need for social mixing and people’s preference, it is essential to understand residents’ perceptions and preferences regarding socially-mixed neighborhoods in order to promote sustainable community development. This study explorers residents’ willingness to accept living in mixed-income communities in Korea, with attention to various levels of income mix. This study conducted an online survey of 2,000 respondents living in seven metropolitan cities in Korea, including Seoul. The study aimed to investigate residents’ comfortability and willingness to move into different mixed-income communities. The results showed that residents with higher openness to diversity are more likely to accept mixed-income communities, but frequent interaction with low-income people reduces higher-income people’s willingness to accept mixed-income communities. As both personal attitudes and experience are important determinants of individuals’ social mix preference, a more systematic community development strategy is required to achieve successful social mixing.
