This chapter discusses and operationalizes the concept of eudaimonic well-being in cities, based on Aristotle's view of human flourishing and Martha Nussbaum's capability approach, within the context of public space. It proposes using Nussbaum's ten human capabilities and the consideration of virtues to evaluate how urban agriculture projects can sustain well-being dimensions through spatial/functional and social affordances. The research argues for a clearer distinction between eudaimonic and hedonic well-being in urban studies.
