Analysis of the Soil Microbiome of a Los Angeles Urban Farm
2020Savanah St. Clair, Maryam Saraylou, Daila Melendez, Norman Senn, Serina Reitz, Destini Kananipour, Angelo Alvarez · Applied and Environmental Soil Science · United States (Los Angeles)
This research characterized the arable soils at Los Angeles Pierce College to address health and food-security challenges, using soil physical/chemical measurements, microbial cultivation, and 16S rDNA sequencing on a citizen-science platform. It found plant-growth-promoting, antibiotic-producing and bioremediating bacteria—including abundant Streptomyces, Bacillus and Methylobacteria—across fields with distinct microclimates, and tests indicated that plant-based oils could control antibiotic-resistant bacteria more effectively than common antibiotics. The authors say the results can guide future trials and product development by identifying target soil microorganisms and the most viable fields.

HealthCommunityA Multi-Sectoral Approach Improves Early Child Development in a Disadvantaged Community in Peru: Role of Community Gardens, Nutrition Workshops and Enhanced Caregiver-Child Interaction: Project "Wawa Illari"
2020Doris González-Fernández, Ana Sofía Mazzini Salom, Fermina Herrera Bendezu, Sonia Huamán, Bertha Rojas Hernández, Illène Pevec, Eliana Mariana Galarza Izquierdo, Nicoletta Armstrong, Virginia Thomas, Sonia Vela Gonzáles, Carlos Gonzáles Saravia, Marilyn E. Scott, Kristine G. Koski · Frontiers in Public Health · Peru (Lima)
In peripheral settlements of the Pachacámac district of metropolitan Lima, Peru, community health promoters delivered a sequence of (1) home and community gardens, (2) 'conscious nutrition' and (3) parenting workshops (ICDP), comparing 113 children aged 0–3 in intervention communities with 127 in control communities at baseline, 8 and 12 months. The interventions significantly reduced the risk of food insecurity (adjusted risk ratio 0.20, 95% CI 0.08–0.51) and of language delay (0.39, 0.19–0.82), but did not significantly improve motor or social/cognitive delay. Multiple micronutrient supplement use lowered motor delay risk (0.12), while households with more pets had higher risk of motor delay (3.24), social/cognitive delay (2.72) and food insecurity (1.73). Because gardens were bundled with nutrition and parenting components, the contribution of the gardens alone cannot be isolated.

Food educationHealthCommunityWho practices urban agriculture? An empirical analysis of participation before and during the COVID‐19 pandemic
2020Lauren Chenarides, Carola Grebitus, Jayson L. Lusk, Iryna Printezis · Agribusiness · United States
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.

2020Omanjana Goswami, Ashaki A. Rouff · Soil Systems · United States (Newark)
Soils from seven community farms in Newark, New Jersey, USA, were analyzed for lead (Pb) concentration and speciation. Single-step extractable Pb concentration ranged from 22 to 830 mg kg−1, with 21% of samples exceeding the NJDEP limit of 400 mg kg−1 for residential soils. Lowest Pb concentrations were detected in raised beds, while uncultivated native soil and parking lot samples had the highest values. Although most Pb is associated with reducible and oxidizable soil fractions, indicating a lower risk of mobility and bioavailability, Pb exposure through ingestion and inhalation pathways remains a concern when directly handling the soil.
