A program in Manado, Indonesia, aimed to enhance food security and self-reliance by promoting chili cultivation in home gardens through socialization, counseling, and seed distribution. While it provided positive economic impacts, the program faced challenges including limited access to agricultural inputs and post-program plant maintenance. Further research and continued mentoring were recommended to evaluate its effectiveness and maximize impact.

Lena Schmeiduch, Émile Thévenot · International Review of Education · Global

This study explored the potential for lifelong learning within sustainability-led initiatives, such as ecovillages and community-supported agriculture, through the theoretical lens of Noah Sobe's four pillars of lifelong education. While these initiatives offer opportunities to address sustainability-related challenges, their insular nature and limited accessibility have drawn criticism in the literature on sustainability transitions. The analysis suggests that these initiatives and lifelong learning agendas frequently converge in their framing of sustainability issues.

This qualitative study reviewed data from 32 counties in Iowa over five years to assess stakeholder participation in Master Gardener community garden donation programs. The analysis found that while these programs engage many stakeholders, the involvement of food pantry patrons in the planning process was low. This low patron involvement limits the programs' ability to effectively serve the community and achieve sustainability and efficacy in providing fresh produce.

At a hybrid food and resource center with an attached community garden in California, USA, a longitudinal, sequential explanatory mixed-methods study of 30 patrons (mean age 45.9, 73.3% women) combined quantitative measures (survey and skin carotenoids) with qualitative semi-structured interviews to examine barriers to and facilitators of fruit and vegetable intake. Skin carotenoid levels, a biomarker of fruit and vegetable intake, were largely unchanged before and after (P = .51); among the 26 participants interviewed, facilitators cited included perceptions of quality and alignment with health goals, while barriers included mental health and competing priorities, leading to the conclusion that programs aiming to improve fruit and vegetable intake should prioritize non-diet determinants.

Chmielewski J., Wszelaczyńska E., Pobereżny J., Florek-Łuszczki M., Gworek B. · Sustainability · Poland

The study sampled 112 items — 72 vegetable and 40 fruit — from 16 allotment gardens in Warsaw and measured Fe, Mn, Zn, Cu, Pb and Cd. Vegetables accumulated markedly more heavy metals than fruits, and leafy vegetables grown near high-traffic roads carried the highest Pb, Cd and Zn. Lead exceeded permissible limits by six to twelve times and cadmium by one to thirteen, leading the authors to advise against growing tomatoes in urban settings. Only trace amounts appeared in fruits, and the Hazard Index rated the fruits alone as safe. The paper calls for continuous monitoring of urban garden soils, remediation of contaminated ground and safer growing practices.

Interviews and a survey examined how residents of Bandung perceive the ecosystem services of homegarden-based urban agriculture. Residents themselves judged the gardens' contribution to overall food security to be only supplementary, even though they supply fresh produce. Their value was widely recognised elsewhere: biodiversity conservation, microclimate regulation, disaster risk reduction, social cohesion and mental well-being. Limited space, lack of knowledge and competing land uses emerged as the barriers, and the authors conclude that education and policy support are the levers for wider uptake.

This review identifies challenges for strawberry cultivation in urban production systems, noting that new urban farmers often lack the specialist knowledge of commercial growers. Common bottlenecks include plant physiology, pathogen management, choice of propagation material, fertigation, pollination, and environmental requirements. This knowledge gap appears to result in the abandonment of strawberries as a crop of choice in urban systems.

This mixed methods study investigated the impact of a middle school garden project on 6th-graders’ school connectedness. Surveys of 46 middle school students indicated that most had home gardening experience and enjoyed the school garden activities. However, pre-post results did not show increased school connectedness following the garden unit, as ratings were moderately high both before and after. Interviews with 25 participants revealed that the garden project facilitated home-school, student-student, and student-teacher connections, serving as a context for engagement and enjoyment for students.
