Paula Mota Santos · Social Inclusion · Portugal (Porto)

Grassroots urban horticultural plots (hortas) in the Porto Metropolitan Area, Northern Portugal, are informal communities that have existed for decades, often involving over 20-30 people. However, these low-income urbanite horticultural communities are not cherished by city governance, which does not prevent their destruction. This incompatibility between urban governance and grassroots communities hinders the right to the city for the low-income urbanites who created them.

A study collected data from 352 households in two major Bangladeshi cities to predict organic food production intention and behavior in urban rooftop gardens using the value-belief-norm (VBN) theory and theory of planned behavior (TPB). Findings showed that biospheric and egoistic values improved ecological worldview, which, along with awareness of consequences and social norms, predicted personal norms. Personal and social norms forecasted the intention to produce organic food in rooftop gardens.

Elin Montelius · Journal of Risk Research · Sweden

This paper analyzes the utopia of self-sufficiency as a response to risk and uncertainty, particularly focusing on the growing interest in gardening and cultivating vegetables in Sweden. Using intersectional risk theory, it examines how narratives of self-sufficiency function to address ecological risk and uncertainty, and how utopian narratives can contribute to undoing risk.

Pak choy and sawi exhibited the highest vitamin A and C content respectively, while spinach showed the largest number of highest mineral types including boron, potassium, magnesium, and phosphorus.

Emmanuel Frimpong Boamah · Urban agriculture · Global

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.

Noga Pitowsky‐Nave, Michal Almog‐Bar, Hillel Schmid · Social Work in Mental Health · Global

This paper presents a case study of a community garden in Israel that emerged from a collaboration between a Social Service Nonprofit Organization (SSNO) providing mental health rehabilitation services and a real-estate business firm. Based on interviews with key figures, onsite observations, and document analysis, it examined the inter-organizational dynamics of this collaboration and its benefits and challenges for the SSNO and its service users. The results show that collaborating with a business can offer SSNOs benefits in financial resources and volunteers, but also involves difficulties, which were intensified in the context of a mental-health-focused SSNO.

A 2024 study examines the impact of the "Garden TOOLS" garden-based technology integration program on science teaching self-efficacy among 39 elementary pre-service teachers (PSTs) enrolled in a 300-level science methods course in the rural Midwest, US. Using the STEBI-B instrument to measure change in personal science teaching efficacy (PSTE) and science teaching outcome expectancy (STOE) before and after the intervention, it found that participants in the Garden TOOLS professional development workshops showed a statistically significant increase in PSTE from pre- to post-workshop, and that participants who also implemented the Garden TOOLS lesson in practicum showed increases in both PSTE and STOE.

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.
