Mainstreaming of ecosystem service approaches has been proposed as one path toward sustainable development. Meanwhile, critics of ecosystem services question if the approach can account for the multiple values of ecosystems to diverse groups of people, or for aspects of inter- and intra-generational justice. In particular, an ecosystem service approach often overlooks power dimensions and capabilities that are core to environmental justice. This article addresses the need for greater guidance on incorporating justice into ecosystem services research and practice. We point to the importance of deep engagement with stakeholders and rights holders to disentangle contextual factors that moderate justice outcomes on ecosystem service attribution and appropriation in socio-political interventions. Such a holistic perspective enables the integration of values and knowledge plurality for enhancing justice in ecosystem services research. This broadened perspective paves a way for transformative ecosystem service assessments, management, and research, which can help inform and design governance structures that nourish human agency to sustainably identify, manage, and enjoy ecosystem services for human wellbeing., (© 2022.

Watersheds are settings for health and well-being that have a great deal to offer the public health community due to the correspondence between the spatial form of the watershed unit and the importance to health and well-being of water. However, managing watersheds for human health and well-being requires the ability to move beyond typical reductionist approaches toward more holistic methods. Health and well-being are emergent properties of inter-related social and biophysical processes. This paper characterizes points of connection and integration between watershed management and public health and tests a new conceptual model, the Watershed Governance Prism, to determine the prevalence in peer-reviewed literature of different perspectives relating to watersheds and public health. We conducted an initial search of academic databases for papers that addressed the interface between watershed management (or governance) and public health themes. We then generated a sample of these papers and undertook a collaborative analysis informed by the Watershed Governance Prism. Our analysis found that although these manuscripts dealt with a range of biophysical and social determinants of health, there was a tendency for social factors and health outcomes to be framed as context only for these studies, rather than form the core of the relationships being investigated. At least one cluster of papers emerged from this analysis that represented a cohesive perspective on watershed governance and health; "Perspective B" on the Watershed Governance Prism, "water governance for ecosystems and well-being," was dominant. Overall, the integration of watershed management/governance and public health is in its infancy.

Human well-being is intricately connected to ecosystem services. A keystone contribution to the ecosystem service literature has been the Millennium Ecosystem Assessment, MA, (Ecosystems and human well-being: a framework for assessment, Island Press, Washington, DC; 2003, 2005). Much of the work on ecosystem services to date has focused on the assessment and classification of environmental functions. The need for inclusion of community perspectives in ecosystem assessments has been widely recognized in order to better understand the distribution of impacts and benefits resulting from natural resource use. Communities can offer a direct route to understanding the complex relationships between ecosystems and human well-being and how environmental management affects their livelihoods. Photovoice has been made popular as a tool for participatory needs assessment but it has had limited use in ecosystem assessments to date. The purpose of this paper is twofold: (1) to present the results of a community-level assessment of environmental services in a watershed dominated by pineapple monoculture in Costa Rica; and (2) to evaluate the strengths and the limitations of photovoice as a tool for mapping the relationship between ecosystems and people. I argue that photovoice is an underutilized methodology that has the potential to complement biophysical ecosystem service assessments in the context of impoverished and resource-dependent communities, particularly, since assessing ecosystem services and acting upon that information requires integrating the knowledges of diverse stakeholders, recognizing power imbalances, and grappling with the complexity of social-ecological systems. Processes such as photovoice have the potential to catalyze community self-organization, which is a critical component for empowerment.
