Sustainable agrifood systems are critical to averting climate-driven social and ecological disasters, overcoming the growth paradigm and redefining the interactions of humanity and nature in the twenty-first century. This Perspective describes an agenda and examples for comprehensive agrifood system redesign according to principles of sufficiency, regeneration, distribution, commons and care. This redesign should be supported by coordinated education and research efforts that do not simply replicate dominant discourses on food system sustainability but point towards a post-growth world in which agroecological life processes support healthy communities rather than serving as inputs for the relentless pursuit of economic growth.

The sustainability concept in its current form suffers from reductionism. The common interpretation of “meeting the needs of the present without compromising the ability of future generations to meet their own needs” fails to explicitly recognize their interdependence with needs of current and future non-human generations. Here we argue that the focus of sustainability on human well-being – a purely utilitarian view of nature as a resource for humanity – limits its conceptual and analytical power, as well as real-world sustainability transformation efforts. We propose a broadened concept of ‘multispecies sustainability’ by acknowledging interdependent needs of multiple species’ current and future generations. We develop the concept in three steps: 1) discussing normative aspects, fundamental principles underlying the concept, and potential visual models, 2) showcasing radically diverging futures emerging from a scenario thought experiment based on the axes sustainable-unsustainable and multispecies-anthropocentric, and 3) exploring how multispecies sustainability can be applied to research and policy-making through two case studies (a multispecies stakeholder framework and the Healthy Urban Microbiome Initiative).

Non-technical summary The sustainability concept seeks to balance how present and future generations of humans meet their needs. But because nature is viewed only as a resource, sustainability fails to recognize that humans and other living beings depend on each other for their well-being. We therefore argue that true sustainability can only be achieved if the interdependent needs of all species of current and future generations are met, and propose calling this ‘multispecies sustainability’. We explore the concept through visualizations and scenarios, then consider how it might be applied through case studies involving bees and healthy green spaces.
