Coastal communities are more susceptible to the negative impacts of climate change than those in inland areas. Although, researchers have examined the adaptation measures of costal population to climate change impacts, but little is known about the effect of community-based adaptation strategies on the impacts of climate change, specifically among residents of coastal communities in Lagos, Nigeria. Therefore, this paper bridges this gap in knowledge by investigating the effect of adaptation measures on climate change impacts among residents of coastal communities in Lagos State, Nigeria. The study adopted a mixed methods approach (both quantitative and qualitative) to collect and analyse data. Results revealed that some of the community-based adaptation measures such as tree planting, waste management initiatives, and climate change awareness programmes were critical adaptation measures adopted by the participants. It was recommended that stakeholders and climate adaptation-related practitioners need to scale-up these climate adaptation initiatives because of their effectiveness in strengthening the resilience of the people to climate change impacts.
