This chapter examines alternative governance visions for urban agriculture, or urban food commons (UFCs), through the lens of polycentric governance. It argues that UFCs require a mix of institutional arrangements, including centralized, decentralized, market, cooperative, and command-and-control models, rather than a single approach. Four institutional design parameters are outlined to guide this polycentric vision: multiple decision centers, cross-scale and cross-sector interactions, an overarching rule system, and rule adaptability, exemplified by Chicago's NeighborSpace.

A community-service report on introducing solar-powered hydroponic urban farming in Rejowinangun Selatan village, Magelang City, Indonesia (population density 7,361 people/km²), in response to declining green open space linked to rising population density and land concretisation, which affects food security and self-sufficiency. The programme delivered various approaches to educate and directly involve residents in building hydroponic systems integrated with solar panels, using renewable-energy technology to enable food production in limited spaces such as house terraces. It reports that this increases food independence and security, and that the vegetables produced are described as healthier owing to minimal pesticide use.

A qualitative study of a Conservation Unit in the Brazilian Amazon (the Lago do Cuniã Extractive Reserve) analyzing the role of forests within the water-energy-food nexus, focusing on how traditional populations use non-wood natural resources for their survival. Data were collected through questionnaire-based interviews and non-participant observation. The results show that maintaining forest resources improves water quality, controls erosion and resilience against droughts and floods, contributes to energy supply, and contributes to food safety for residents of the conservation unit. The authors note policy implications for management practices to conserve forests and to protect the quantity and quality of rivers, lakes, and aquatic and agricultural ecosystems in the reserve.

Wendy Davies · · Europe

A historical chapter exploring why monasteries were interested in acquiring gardens in the tenth century. It concludes the likely reasons included increasing the regular supply of garden fruit, legumes and medicinal herbs for expanding monastic communities, along with a regular supply of textile fibres. Some rural monasteries bought gardens in towns and operated shops there, supported by an available road network and plentiful draught animals as necessary elements of a distribution system. Textiles and plant dyes appear to have been supplied to urban communities, and the chapter suggests garden plots may have been acquired specifically to focus on textile and dye plants for cloth production and distribution, marking a new direction in monastic enterprise with a corresponding shift in garden output.

A 2024 paper reports on an educational practice with elementary school students at a community garden at IFG-Anápolis, Brazil, framed around "omnilateral formation" and critical environmental education. Through periodic visits, workshops, and discussion sessions, the practice addressed problems arising from the use and consumption of pesticides in food. It reports that the critical environmental education approach was significant in revealing the latent meanings behind an agribusiness food market based on unrestrained pesticide use.

Matthijs T. Wessels, Shaaban M. Mgana · Urban Forum · Tanzania

Based on ethnographic research in Dar es Salaam, Tanzania — one of the fastest-urbanizing cities in sub-Saharan Africa — this study examines how farmers configure their day-to-day agricultural practices amid urban change. Contrary to narratives that present agriculture as passive in the face of urban growth, it describes farmers building networks of provision through informal access to land and water, supplying food and employment while actively co-shaping the city. Farmers adapt their strategies in response to land pressure and water resource degradation. The paper argues that better representation of urban farmers and irrigated agriculture in urban planning and governance would reduce uncertainty and risk for both farmers and the wider city.

This article examines the Seeding East Buffalo Fellowship (SEBF) program, co-founded by community and academic organizations in Buffalo, NY in 2022, which supported residents of Buffalo's Black neighborhoods in growing their own food, emerging as urban agriculture leaders, and engaging in urban agriculture policy advocacy. The authors, who are co-founders or team members of SEBF, draw on field notes and qualitative interviews with SEBF growers to reflect on lessons from this pilot program. Key lessons for policy change identified are that programs must be rooted in community history, pedagogical strategies must be tailored to local context, and long-term relationships must be fostered.
