The University of Tennessee Extension and research faculty developed the Home Garden Variety Trial (HGVT) program, a citizen science approach for cultivar evaluation. This collaborative effort involved over 450 individual gardeners in more than half of Tennessee's counties, conducting trials in their own gardens from 2017 over five years. The HGVT program serves as an effective tool to introduce gardeners to new crops and cultivars while providing previously unavailable data to researchers, supporting residential and community food production.

The informality of urban agroecological space is examined through methodologies from transdisciplinary border zones, particularly the arts, framing the practice of gardening as an act of creation. Ecosophical, aesthetic and artistic concepts (community eco-art practices and digital eco-art) are integrated with socio-economic-political concepts (strengthening production, citizenship and digital literacy) in the context of informal urban agriculture, sketching an application scenario for inclusive community-resilience methodologies.

This study used choice experiments and latent class analysis in North America to quantitatively examine what drives consumer preferences for growing food in community gardens. It found that providing tools and guidance were the most important contextual factors for participation, that proponents were characterized by high subjective knowledge and perceived benefits, and that opponents had low knowledge. The authors suggest the findings can inform policies promoting sustainable urban food systems.

Emotional well-being (EWB) during household gardening and other activities was measured in the Minneapolis-St. Paul Area, USA, using an app-based Day Reconstruction Method. Among 370 participants, 118 (32%) reported engaging in household gardening. Gardening EWB ranked among the top 5 out of 15 activities for three average EWB measures and was not statistically different from biking, walking, and eating out. Average net affect of gardening was significantly higher for vegetable gardeners, low-income gardeners, and women, while companionship, race/ethnicity, and urban versus suburban location showed no significant difference.

This study examined household-level participation in urban agriculture (community and home growing) before (2017) and during (2020 lockdown) the COVID-19 pandemic in Phoenix, AZ, and Detroit, MI, using two online surveys and bivariate probit models. It found that considerably fewer individuals participated in community gardens compared to home gardening, and overall participation was lower in 2020 than in 2017. The continuity of individuals' participation in growing food at community gardens and home is fragile, and many urban households' food-growing practices may not yet be mainstream, suggesting other barriers inhibit participation.

This study designed and evaluated an agroecological system for a rooftop agricultural model in the high jungle of Peru, associating tomato plants (Rio Grande and Cherry varieties) with vegetable covers. The system demonstrated benefits for family food safety through pesticide-free tomatoes and created a plant barrier on roofs to reduce solar radiation. A new medium-sized tomato variety, suitable for the organic market, was also obtained through natural crossbreeding.

This study surveyed 187 gardeners from 18 urban community gardens in California's central coast to investigate how socio-demographic factors affect pest reporting and management practices. Most gardeners reported pests, with ethnicity, time spent in gardens, and agricultural employment influencing reporting likelihood. The majority used curative, non-synthetic practices, but the likelihood of using curative practices varied by gardeners' ethnicity, time spent in gardens, and gender.

In urban community gardens on the central coast of California, USA, gardeners' adaptation of management behaviors to drought was investigated across three periods: before, during, and after the longest drought. Structural equation modeling and multivariate analyses were used to assess the impact of water policies and gardener characteristics. Findings showed that nature relatedness and gardening experience influenced drought concern, which then impacted behavioral change. Water policies were found to promote and maintain behavioral change and conservation practices even when concern was absent.

This field study in Blacksburg, VA, investigated the effects of exceptional quality (EQ) biosolids on urban soil properties and vegetable yield over two years (2016-2018). Biosolids increased soil carbon storage by 37-84% compared to controls, but soil nitrogen availability was lower than expected. Reclamation rates of biosolids resulted in higher yields for cabbage (∼3.1 kg m⁻²) and Siberian kale (∼1.1 kg m⁻²) than inorganic fertilizer (1.0 kg m⁻² and 0.4 kg m⁻² respectively) in fall 2017, indicating potential to increase vegetable yield despite limiting soil conditions.
