Efectividad del Huerto Urbano: Un Enfoque para el Bienestar de los Adultos Mayores Urban Garden Effectiveness: An Approach to the Well-being of Older Adults
2025Marisol Silva-Vera, María de Jesús Jiménez González, Laura Varela Almanza · JÓVENES EN LA CIENCIA · Mexico
A quasi-experimental study in Mexico with 21 adults over 65 evaluated a community urban garden intervention for nutritional status. Participants showed increased nutrition knowledge, a 47.7% rise in vegetable intake, and a 23.8% increase in physical activity. However, anthropometric variables did not show significant differences, indicating limited impact on physical measurements despite positive changes in knowledge and habits.

2024Wendy Demark-Wahnefried, Robert A. Oster, Kerry P. Smith, Harleen Kaur, Andrew D. Frugé, W. Walker Cole, Julie L. Locher, Gabrielle B. Rocque, Maria Pisu, Jennifer R. Bail, Harvey Jay Cohen, Douglas R. Moellering, Cindy K. Blair · JAMA Network Open · United States (Alabama)
A randomized trial in Alabama, USA, assigned 381 older cancer survivors (mean age 69.8 years, 69.0% female) with suboptimal vegetable and fruit intake, physical activity or physical function to a one-year home vegetable gardening intervention (supplies plus mentoring by certified master gardeners) or to a waitlist. The primary outcome — a composite index of improvement in vegetable and fruit intake, moderate-to-vigorous physical activity and physical function — did not differ significantly (4.5% intervention vs 3.1% waitlist, P=.53), nor did vegetable and fruit intake between arms (mean difference 0.3 servings/day, P=.10). The intervention arm did show significant gains in physical performance (2-minute step test +6.0 steps; 30-second chair stand +0.8 repetitions), perceived health (+8.4 points on a 100-point scale) and gut microbiome alpha diversity. The COVID-19 pandemic significantly moderated effects, so the trial does not establish that gardening halts functional decline in older adults.

This review examines the potential of urban agriculture by the elderly to support food security. While urban agriculture could produce 180 million tons of food globally per year, representing 10% of total global food production, it is currently insufficient to meet urban food needs, with urban food supply still heavily reliant on rural areas and imports. With an increasing urban elderly population, empowering seniors through urban agriculture technologies like vertical farming is proposed as an opportunity for food security.

2020Tomoko Imoto, Nobutaka ISHITSUKA, Cheligeer, Kiyohide Morita · JOURNAL OF RURAL SOCIETY AND ECONOMICS · Japan
This study investigated allotment garden use among child-rearing generations in Japan, identifying preferences for "free space (play area)," "staff to answer questions," and "events." A questionnaire survey of first-grade parents revealed a high potential demand for allotment gardens, with preferences for lower fees, play areas, cultivation guidance, and events. However, an analysis using a cross-effect model found a disconnect between preferences for garden use and food preferences, as those who buy domestic products generally did not value events, indicating a "food-agriculture gap."
