Social capital is increasingly recognized as a key determinant of adaptive capacity to climate change. Beyond formal adaptation infrastructure like insurance and public disaster support programmes, it can be difficult to identify the role that informal social capital—such as relationships, trust, and mutual support between community members—plays in climate adaptation. Drawing on a multi-site qualitative study in the Canadian Prairie region, this paper examines how three forms of social capital (bonding, bridging, and linking) shape rural communities’ adaptation to climate extremes. Based on in-depth interviews with 163 community members, the findings demonstrate how social capital contributes to adaptive capacity, particularly in rural areas where more formal supports may be absent or lacking. We examine how social capital is affected by existing socio-economic sensitivities, such as rural depopulation, which can reduce informal social capital while simultaneously increasing people’s dependence on it. The findings indicate the strengths and limitations of bonding and bridging social capital, particularly in the face of future climate extremes that may exceed local adaptive capacity. Further, we find that informal social capital may also reinforce gender inequality, exclusion, and inter-group differences, indicating its limitations for socially inclusive adaptation. Addressing these structural factors can help communities move past coping and toward long-term adaptation. In the face of increasing climate risks, our findings suggest the importance of public supports that are attentive to local strengths, gaps, and social relations.
