Climate change poses a significant threat to the livelihoods of smallholder farmers in South Africa, particularly in rural areas where dependence on rain-fed agriculture and limited institutional support heighten vulnerability. This study investigates how different forms of social capital (bonding, bridging, and linking) influence climate change adaptation strategies among smallholder farmers in Bergville, KwaZulu-Natal. A mixed-methods design was employed, combining a household survey (n = 150), focus group discussions, and key informant interviews. Households engaged in smallholder farming were purposively identified and randomly selected within the study ward. To accommodate varying literacy levels, structured questionnaires were administered through interviewer-led surveys. Quantitative data were analysed using descriptive statistics, chi-square tests, and a probit regression model, while qualitative data were thematically analysed to contextualise adaptation decisions and social dynamics. The findings show that trust in peer information, farmer group membership, collective action, and access to extension services significantly increase the likelihood of adopting climate adaptation practices (p < 0.05). While bonding social capital supports short-term coping, limited bridging and linking social capital constrain access to institutional resources and climate information. By explicitly operationalising and empirically distinguishing these dimensions of social capital, the study provides context-specific evidence on how uneven social networks shape adaptation outcomes. Strengthening inclusive institutional linkages and extension services is essential for promoting long-term climate resilience among smallholder farmers in rural South Africa. This study contributes to the international literature by providing empirical evidence on the differentiated roles of social capital dimensions in shaping adaptation outcomes in resource-constrained rural contexts. The findings highlight the need for policy interventions that strengthen institutional linkages, improve extension service delivery, and promote inclusive access to adaptation resources to enhance long-term climate resilience.
