Given the reality of unprecedented climate change, which has negatively impacted and continues to impact societies and economies, exploring the collective efficacy (CE)-)–adaptation nexus is urgent. Against this backdrop, the current contribution systematically reviews the literature on CE and adaptation by utilising the reporting standards for systematic evidence syntheses (RoSES). The aim is to establish the state of knowledge on the association between CE and adaptation to climate change and its variability globally. The appraisal of eight articles that satisfied the inclusion criteria demonstrates the limited and geographically skewed distribution of publications on the CE–adaptation nexus. CE has not been extensively operationalized in parts of the highly vulnerable African continent. CE and adaptation research in African countries is imperative considering their collectivistic culture, high vulnerability, and low adaptive capacity. Evidence on the positive association between CE and adaptation to climate change and climate-related hazards has been accrued. This is the context within which this paper advances the need for increased research across socio-cultural contexts to advance knowledge on the CE–adaptation nexus and facilitate effective and sustainable adaptation.
