In his talk, Julian will outline the concept of just sustainabilities as a response to the ‘equity deficit’ of much sustainability thinking and practice. He will explore his contention that who can belong in our cities will ultimately determine what our cities can become. He will illustrate his ideas with examples from urban planning and design, urban agriculture and food justice, and the concept of sharing cities. Julian Agyeman Ph.D. FRSA FRGS is a Professor of Urban and Environmental Policy and Planning at Tufts University. He is the originator of the increasingly influential concept of just sustainabilities, the intentional integration of social justice and environmental sustainability. He centers his research on critical explorations of the complex and embedded relations between humans and the urban environment, whether mediated by governments or social movement organizations, and their effects on public policy and planning processes and outcomes, particularly in relation to notions of justice and equity. He believes that what our cities can become (sustainable, smart, sharing and resilient) and who is allowed to belong in them (recognition of difference, diversity, and a right to the city) are fundamentally and inextricably interlinked. We must therefore act on both belonging and becoming, together, using just sustainabilities as the anchor, or face deepening spatial and social inequities and inequalities.
