This chapter discusses the relationship between community gardens and wellbeing, viewing wellbeing as a cultural field. It explores how gardeners experience wellbeing through their gardening and what these experiences reveal about their lifestances. The analysis shows that gardening can contribute to collective wellbeing through transformative engagement with ethics and ontologies, and that community gardens can serve as "everyday utopias" for expressing critique and desire for change. It identifies both the possibilities and limits of community gardens in fostering holistic, relational, transformative approaches to wellbeing.

This study investigated differences in the predation rate of lepidopteran larvae across El Niño phases within an urban-agricultural landscape in Southcentral Mindanao, the Philippines. Predation rates were considerably higher in the pre-El Niño phase (mean 18.24%) than during the peak of the El Niño phase (mean 6.41%) and showed a slight, yet statistically insignificant, rise in the post-El Niño phase (mean 9.48%). Although predation by arthropods on herbivorous preys remained predominant during all periods, vertebrate predation was related to the warmer and drier conditions of El Niño associated with the 2023 ENSO.

Francis Mwaijande · African Journal of Empirical Research · Tanzania

This study, using a mixed-methods approach with 600 respondents from urban and peri-urban farmers and agri-food supply chain producers in Tanzania, confirmed urban agriculture's contribution to food availability, accessibility, stability, and utilization. However, it found that urban agriculture is not well-integrated into urban food and poverty reduction policies in Tanzania and is practiced without legitimate policy and legal frameworks. This policy gap indicates an inadequate policy enabling environment for urban agriculture to enhance food security.

Inger‐Lise Saglie · · Norway

This chapter investigates the motivations for urban agriculture policies in three Norwegian cities: Oslo, Bergen, and Trondheim. Five categories of motivations were identified: urban "green" development (environmental friendliness, biodiversity), food production and alternative food systems (linking to peri-urban agriculture), provision of social meeting places and community building, municipal welfare services (work training, integration, health promotion), and active citizenship and co-creation of city development. While motivations were similar across cities, their emphasis varied.
