Incorporating stakeholder engagement into environmental management may help in the pursuit of novel approaches for addressing complex water resource problems. However, evidence about how and under what circumstances stakeholder engagement enables desirable changes remains elusive. In this paper, we develop a conceptual framework for studying social and environmental changes possible through stakeholder engagement in water resource management, from inception to outcomes. We synthesize concepts from multiple literatures to provide a framework for tracing linkages from contextual conditions, through engagement process design features, to social learning, community capacity building, and behavioral change at individual, group, and group network levels, and ultimately to environmental change. We discuss opportunities to enhance the framework including through empirical applications to delineate scalar and temporal dimensions of social, behavioral, and environmental changes resulting from stakeholder engagement, and the potential for negative outcomes thus far glossed over in research on change through engagement.

Comanagement of natural resources is a well-established approach to the management of common-pool resources such as small-scale fisheries, operating in multiple contexts and settings for over two decades. These programs are expected to be adaptable and promote social and ecological benefits, such as sustainable livelihoods and biodiversity goals. As programs mature, it is important to consider how some core principles of comanagement have manifested in practice, as well as whether they deliver on these promised benefits. Drawing from the conservation, small-scale fisheries, and fisheries management literature, this paper examines three fundamental principles of fisheries comanagement: participation, equity, and power. The conceptualization, definitions, and measures of each theme are presented, with discussion of the current gaps in the literature. We also demonstrate the deep interrelationships between these key dimensions of comanagement, and the need for greater attention to their combined influence on comanagement outcomes and processes. While the literature offers foundational ideas for incorporating these themes into fisheries comanagement practice, tethering these concepts to clear, but context-specific goals and practices is essential for improving social outcomes. We find that key goals of fisheries comanagement could be impeded by the lack of depth in addressing these themes in practice, and suggest the need for greater critical attention to their expressions in comanagement processes.

Participatory modeling (PM) is an engaged research methodology for creating analog or computer-based models of complex systems, such as socio–environmental systems. Used across a range of fields, PM centers stakeholder knowledge and participation to create more internally valid models that can inform policy and increase engagement and trust between communities and research teams. The PM process also presents opportunities for knowledge co-production and eliciting cross-sectional and longitudinal data on stakeholders’ worldviews and knowledge, risk assessment, decision-making, and social learning. We present an overview of the stages for PM and how it can be used for community-based, stakeholder-engaged social science research.

“Blue” (aquatic) food systems have a vital role in providing nutrition, livelihoods, and food security for coastal communities, but addressing and evaluating issues of equity and social resilience continue to challenge small-scale fisheries management. We examine how marine aquaculture and co-management approaches that integrate traditional institutions can support food sovereignty for more equitable blue food systems. Interviews with stakeholders in 11 fishing communities in Samoa indicate that several benefits associated with food sovereignty are derived from co-managed village fish reserves. Reserves support biodiversity health and are a source of culturally valued seafoods that build food security, social capital, and sustainable livelihood opportunities for women. Local values, food systems, providers, and consumers are centered, though traditional hierarchies present challenges for equitable decision-making. Our findings demonstrate how incorporating food sovereignty into the operation and evaluation of fisheries co-management can aid in addressing equity and resilience.
