Can people be sentinels of sustainability? Identifying the linkages among ecosystem health and human well-being

Human well-being depends on the health of ecosystems, but can human well-being also be an indicator of ecosystem health, and perhaps even sustainability? Research shows that ecosystem health and human well-being are often mutually reinforcing, whether in the direction of wellness and sustainability or poverty and degradation. However, while well-being is increasingly recognized as an important consideration when managing ecosystems, human needs and activities are often still thought of only in terms of their negative impacts on ecosystems. In this essay, we explore the proposition that there can be a mutually constitutive relationship between people’s well-being and the health of ecosystems, and discuss what such a relationship would mean for expanding the use of human well-being indicators in ecosystem-based management. Specifically, we discuss two areas of theory: ecosocial theory from social epidemiology and the marginalization–degradation thesis in political ecology; collectively, these provide a justification, in certain circumstances at least, for thinking of well-being as not just an add-on in natural resource management but as an indicator of ecosystem health and a prerequisite of social-ecological sustainability. We conclude with a discussion of future research needs to further explore how human well-being and ecosystem health interact.
