The value of diverse perspectives in social-ecological systems research and transdisciplinarity is well recognized. Human well-being and how it is derived from dynamic ecosystems is one area where local knowledge and perspectives are critical for designing interventions for sustainable pathways out of poverty. However, to realize the potential to enrich the understanding of complex dynamics for sustainability, there is a need for methods that engage holistic ways of perceiving human-nature interactions from multiple worldviews that also acknowledge inequalities between scientific and other forms of knowledge. To date, photovoice has been used to elicit local knowledge and perspectives about ecosystem changes and ecosystem services. We expand this to explore the utility of the method for facilitating the mobilization of plural insights on human well-being, which is subject to complex social-ecological dynamics, and its role in processes for coproduction of knowledge that acknowledges the need for equity and usefulness for all actors. Drawing on two cases, one in community-based marine protected areas in Kenya and one dealing with agricultural decline and rural-urban migration in South Africa, we demonstrate two modes of application of photovoice: as a scoping exercise and as a deep learning tool. The studies descriptively illustrate how photovoice can depict the hidden and often neglected intangible connections to ecosystems, plural and disaggregated perceptions of complex social-ecological dynamics, and issues of access and distribution of ecosystem benefits. The studies also show how photovoice can encourage equitable participation of nonacademic actors in research processes and in particular contribute to mobilization of knowledge and translation of knowledge across knowledge systems. We discuss how local perspectives may be further recognized and incorporated in transdisciplinary research and reflect on the practical and ethical challenges posed by using photographs in participatory research on social-ecological systems.

Marine protected areas (MPAs) have historically been implemented and managed in a top-down way, excluding resource-dependent users from planning and management. In response to conflict and non-compliance, the governance of marine resources is increasingly embracing community-based approaches, assuming that by putting communities at the forefront of planning and management, participation will increase, causing positive social and ecological impacts. Given the relative newness of community-based MPAs, this study explores how resource users perceive their impacts on ecosystem services (ES) and human well-being (HWB). This study, explores two community-based MPAs called tengefus in Kenya using mixed qualitative methods, including a participatory photography method called photovoice. Participation in and donor support for tengefus influences how resource users perceived tengefus and their impacts on ES and HWB. Individuals who were engaged in the tengefu from the inception or held official positions perceived more positive impacts on ES and HWB compared to those not as involved. Tengefus were often viewed by communities as attractors for external support and funding, positively influencing attitudes and feelings towards conservation. One site, the first tengefu in Kenya, had more external support and was surrounded by positive perceptions, while the other site had little external support and was surrounded by more conflict and mixed perceptions. This study exemplifies the complex social political dynamics that MPAs create and are embedded within. Community-based MPA initiatives could benefit from ensuring widespread engagement throughout the inception, implementation and management, recognizing and managing expectations around donor support, and not assuming that benefits spillover throughout the community.
