摘要

Coastal communities in Bangladesh are experiencing substantial livelihood impacts from climate change and natural hazards, largely owing to their dependence on climate-sensitive natural resources. However, there is a paucity of research regarding the effects of climate change on the livelihood capitals of coastal communities in southeastern Bangladesh. In this study, we examined perceptions of local communities (elderly people) on climate change and associated impacts on livelihood capital in the past 30 years in seven villages in southeastern coastal Bangladesh. Following the stratified simple random sampling technique, we collected data by interviewing 170 households near the coast (within 1 km) and 150 households away from the coast (1–3 km), using a pretested questionnaire and conducting two focus group discussions. We also employed the sustainable livelihood framework (SLF) to analyze villager livelihoods, integrating both qualitative and quantitative data to comprehensively understand local livelihoods. The results indicated that respondents, regardless of their coastal proximity, possess substantial knowledge of climate change due to their extensive experiences. Over 80% of respondents across the locations perceived that temperature, summer duration, erratic rainfall, storms, and lightning have intensified over the past 30 years. A significantly higher number of respondents residing near the coast (p ≤ 0.05) perceived an increase in the frequency of tidal surges over the past 30 years, while a significantly higher number of respondents living away from the coast (p ≤ 0.05) reported a decrease in the availability of surface water. About 60–96% of respondents residing near the coast, significantly differing from those living away from the coast, reported that climate change had a medium to high impact on human, physical, natural, and social capital, and these adverse effects have significantly influenced the financial capital of respondents. These impacts on different capitals made respondents living near the coast more vulnerable. In response to adapting to these adverse effects on livelihood capitals, they have implemented various livelihood strategies, with opportunities for further diversification.
