Sustainable adaptation for resolving climate displacement issues of south eastern islands in Bangladesh

Abstract

Purpose

Climate change is affecting people displacement in Bangladesh by both sudden environmental events and gradual environmental change. This paper aims to assess the sustainable adaptation measures for resolving the displacement problem induced by climate change considering the socioeconomic differences between the past and the present location of living places for island dwellers of the south-eastern coast of Bangladesh.

Design/methodology/approach

Both qualitative and quantitative approaches were adopted for conducting the study. The main tool of the household survey was a questionnaire survey. In addition to the estimate of displacement, the authors have used hazard impact analysis, weightage analysis and sustainable adaptation analysis with various ranking. Meaningful data were analyzed through SPSS software and presented through statistical techniques.

Findings

Climate change-induced different natural disasters, such as cyclone, tidal surge, tidal flood and coastal erosion, were frequent in the study areas and responsible for mass displacement. After displacement, people lost not only their identity but also social and cultural harmony and faced different economic and environmental crises. However, nearly 20 types of adaptation options were identified for protection from the displacement of coastal people.

Practical implications

The study prescribed 11 specific criteria and 4 principles of sustainable adaptation options for resolving the climate displacement problem. Moreover, seven adaptation practices showed high sustainability, ten showed medium sustainability and five showed low sustainability in terms of effectiveness, efficiency and implementation ability.

Originality/value

The study would help to establish sustainable adaptation measures through the combination of environment, economic and social harmony with regard to the Sustainable Development Goals.
