This article argues that while vertical farms (VFs) are often presented as indispensable for sustainable cities, their purported sustainability is difficult to achieve without structural changes to reduce social inequalities. Critiques of urban agriculture, including VFs, point to their contribution to gentrification, racialization of space, and vulnerability to real estate capital, indicating a critical finding regarding equity. The article advocates for VFs to be appropriated by social movements to foster critical stances against conventional agriculture and catalyze urban utopias.

This chapter presents the development of public policies and the main actors in urban agriculture in three Norwegian cities: Oslo, Bergen, and Trondheim. While showing common traits in institutionalization, differences exist in the role of voluntary groups, bottom-up versus top-down processes, networking, relationship to peri-urban agriculture, and implementation in plans. Oslo's approach is politically driven with traditional participatory methods, developing urban agriculture as a social activity and professional food production. In Bergen, the voluntary sector actively co-creates policy and runs a competence center. Trondheim's policy is co-produced annually with growers based on their experiences, with a strong connection to professional agriculture, and has consciously chosen not to develop specific strategies for urban agriculture.

This essay explores the conjuncture of interspecies reciprocity, hospitality, gift-giving practices, and the co-creation of urban spaces, focusing on the potential for and complexity of neighborly relationships between humans and plants. Borrowing the concept of the ‘good neighbor’ from Robin Wall Kimmerer’s Braiding Sweetgrass, it considers the conditions under which relationships based on care and responsibility can thrive through ‘circular reciprocity’. Sites for close interspecies encounters, like urban foraging practices and community gardens, show the potential of a caring and attentive striving toward neighborliness but also reveal the multiplicity and ambiguity of what can be considered different, sometimes irreconcilable, interests and needs of various urban dwellers. Nevertheless, this essay argues that the practice of becoming ‘good neighbors’ ultimately benefits both humans and plants.
