Abstract

Small-scale fisheries are vital for global livelihoods and food security yet remain highly vulnerable to environmental changes due to marginalization and reliance on natural resources. In contexts where formal governance is weak, small-scale fishers often develop self-governance arrangements (e.g. fishing cooperatives or patron-client relationships) that significantly influence their fishing behavior and resilience to environmental stressors, including climate change. However, evidence on how these social structures impact fishers’ adaptive capacity and responses to climate change impacts remains limited. Using data from 445 surveys across six communities in Nayarit, we examine the role of three self-governance arrangements (fishing cooperatives, patron-client relationships, and independent fishers) in shaping fishers’ responses and adaptive capacity to climate change. Our findings reveal widespread reliance on coping strategies, such as borrowing money and increasing fishing effort, with patrons playing a key role in providing access to economic and material assets. However, patron-client relationships exhibit low social organizational capacity, potentially undermining community cohesion. A multinomial logistic mixed model shows that both patron-client relationships and fishing cooperatives are associated with unsustainable fishing practices as adaptation strategies, suggesting risks of maladaptation. These results highlight the importance of self-governance structures in shaping fishers’ adaptive capacity, showing how different arrangements provide access to distinct economic, social, and institutional assets that influence responses to climate change. As climate impacts intensify, understanding these social structures is crucial to fostering sustainable, climate-resilient practices and safeguarding the livelihoods of coastal communities.
