A review of 22 studies (2001-2024) across six countries, primarily the US and Canada, examined how high school garden programs support adolescent food security and resilience. Findings indicated contributions across multiple socio-ecological levels, but uneven implementation significantly constrained their overall impact. Specifically, opportunities for shared decision-making were limited, and short-term, inconsistent support for policy, funding, and governance structures restricted long-term effectiveness.

This study introduced a social impact accounting framework, "accounting for the loops," for sustainability education for climate action (SECA), applying it to a university-led community garden case study. It found that a sense of belonging and personal recognition activate positive reinforcing loops. However, project size and community autonomy counterintuitively triggered balancing loops, leading to increased bureaucratic obstacles and institutional support needs, which negatively impacted participant motivation.

This thesis explores improving Dominica's urban agricultural sector, examining challenges like hurricanes, landslides, temperature shifts, limited adoption of advanced farming techniques, an aging farmer population, and soil erosion. The proposed Agricultural Learning Facility aims to address these issues by leveraging smart farming methods and enhancing traditional practices. However, the proposed greenhouse and hydroponic systems cannot completely replace traditional farming practices, but rather help increase food production.

A book chapter on biodiversity education centered on seeds and plant life cycles. It states that industrial agriculture has reduced genetic diversity through monocultures and patented hybrid varieties, making small farmers dependent on large seed companies. F1 hybrids, while high-yielding, are not seed-proof — saved seed from them does not reproduce the parent traits — and this contributes to genetic erosion, limiting plants' ability to adapt to climate change and disease. The chapter notes that many people lack an in-depth understanding of plant cycles, and that studies show deficits among students specifically in classifying and explaining seeds and their role in a plant's life cycle. Hands-on experiences such as those in school gardens are said to foster better understanding and a sustainable connection to nature. Knowledge of biodiversity and plant cycles is described as crucial for topics such as healthy diets, regionality, and climate adaptation, and integrating this content into education is presented as contributing to Education for Sustainable Development (ESD) and Convention on Biological Diversity (CBD) goals.

A study measuring soil lead by X-ray fluorescence at 31 Brooklyn public schools with active garden programmes, sampling both garden beds and adjacent school grounds. Proximity to 306 known environmental hazard sites was mapped geostatistically and combined with demographic data and soil-management surveys. Of the samples, 42% exceeded the US EPA's minimum screening level for child-accessible soils near known lead sources (100 ppm); garden soils showed lower average lead concentrations than adjacent school-ground soils. The authors argue that soil lead in schools, and the disparities in it, have received far less attention than lead in paint and water.

Limachi Pérez, Vicente · Macedonian Journal of Medical Sciences (University of Skopje) · Bolivia (Cochabamba)

This study examined the influences of family, school, and sociodigital networks on environmental awareness among secondary school students in urban and rural Cochabamba, Bolivia. Data from three schools showed students' environmental concerns varied by region, and the internet was their primary information source. Despite isolated initiatives like school gardens, schools did not effectively integrate environmental education into the curriculum, limiting its formative impact.

This study analyzed the impact of generative AI on the intelligent transformation of urban agriculture from theoretical and technical perspectives. Generative AI was shown to be applicable in production optimization, marketing innovation, and farmer education, enhancing resource utilization efficiency and industrial sustainability. However, its widespread application faces challenges such as agricultural data silos, model adaptability, cost, and talent shortages, requiring collaborative support from policies, technologies, and talent.

Odeimy Sarría-Crespo, Mayelin López-Roque, Wilfredo Sis-Sánchez · Revista Metropolitana de Ciencias Aplicadas · Cuba (Cienfuegos)

A ten-month non-experimental study at the "Pueblo Griffo Viejo" organic farm in Cienfuegos, Cuba, identified limiting factors in vegetable production through surveys, field observations, and documentary review. The research found low yields due to poor substrate quality, inadequate water management, limited organic matter, and insufficient training participation. Additionally, the workforce's low educational level hindered efficient agricultural practices.

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 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.

This action research study explored transdisciplinary teaching and learning in an urban agriculture master's program using qualitative methods. Students demonstrated high inter- and intrapersonal competencies and cross-disciplinary idea development. However, a critical finding was that the potential for collaboration with external partners (case owners) was not fully exploited and requires further development.

Margaretha Häggström, Mårten Häggström · The Trumpeter · Sweden

This four-year exploratory study in a clearcut in western Sweden investigated the feasibility of cultivating crops in a nutrient-poor, shadowless environment to support biodiversity. The study found that while it was possible to grow potatoes, peas, and some summer flowers without special efforts, it was difficult to grow other vegetables and root vegetables. The project suggests that planting activities in clearcuts may impact people's sense of human-nature identity and respect for the natural environment.

A cluster randomized controlled trial in rural Nepal (n=680 school children aged 9-13 across 30 schools) investigated whether an integrated school and home garden intervention improved hemoglobin levels and reduced anemia. The intervention did not lead to a direct significant reduction in anemia, as nutritional improvements were not strong enough to impact hemoglobin levels. However, the program indirectly improved hemoglobin levels for children under 12 by increasing good food and hygiene practices at home, particularly for girls, young children, and those with literate caregivers.
