Unsustainable development in the Caribbean has reduced the effectiveness of coastal ecosystems as ecological buffers against climate variability, climate change, extreme weather events, and sea level rise. Using Barbados as a case study, the research conducted first examined ecosystem degradation. Second, an analysis of adaptation options for climate change and rising sea levels was undertaken. Based on the study conducted, conclusions were drawn on the implementation challenges of adaptation measures and approaches, and areas for future research. The research found that hard engineering is highly prioritised because of the vulnerability of settlements, infrastructure, and beaches to erosion. Beach protection in particular receives significant attention because beach tourism is economically significant. Additionally, beach nourishment is popular in alleviating erosion. A major finding is that reactive and standalone protective efforts are less effective, so that hard and soft engineering measures, though economically costly, are combined responses. On the other hand, retreat and relocation are controversial given limited space, and are economically and politically costly.
