School Garden Prevalence Before and After the Implementation of the Healthy Hunger‐Free Kids Act
2022Naomi Reyes, Montserrat Ganderats‐Fuentes, Francesco Acciai, Jessica Eliason, Punam Ohri‐Vachaspati · Journal of School Health · United States (New Jersey)
This study examined school garden prevalence in 148 K-12 schools across four low-income New Jersey cities between 2010-2011 and 2017-2018, before and after the Healthy Hunger-Free Kids Act (HHFKA) of 2010. Garden prevalence increased from 19% in 2010-2011 to 32% in 2013-2014, but this increase was not sustained over time. Furthermore, schools with a majority Hispanic student enrollment had approximately half the odds of having a garden compared to schools with a majority Black student enrollment.

2022Anithadevi Kenday Sivaram, Logeshwaran Panneerselvan, Aravind Surapaneni, Elliot Lee, Kurunthachalam Kannan, Mallavarapu Megharaj · Environmental Advances · Australia
This study assessed 19 commercially available composts, garden soils, and potting mixes in Australia for 38 per- and polyfluoroalkyl substances (PFAS). Total PFAS concentrations ranged from 1.26 to 11.84 µg kg−1 (dry weight), with total perfluorinated carboxylic acids (ƩPFCAs) being higher than perfluoroalkyl sulfonic acids (PFSAs). The total oxidizable precursor assay (TOPA) showed an increase in short-chain ƩPFCAs (0.48 to 7.63 µg kg−1) in composts and potting mixes, indicating transformation of PFCAs precursors. The measured concentrations of short-chain PFCAs in soil substrates have the potential to contribute to plant uptake and food chain transfer of PFAS to humans.
Contamination & food safetyHealthCompostFactors Influencing the Sustained Adoption of Innovative Techniques by Urban Farmers in Lubumbashi, Democratic Republic of Congo
2022Maurice Kesonga Nsele, Jules Nkulu Mwine Fyama, Kevin Maréchal, Thomas Dogot · Agriculture · Democratic Republic of Congo (Lubumbashi)
In urban agriculture in Lubumbashi, Democratic Republic of Congo, an innovative technology package was disseminated, but ten years later, farmers' daily income was less than USD 1.25, and critical exceedances of heavy metal content standards in crops were recorded. Survey data from 202 farmers and a Logit model identified factors influencing the sustained adoption of two innovations: motor pumps and integrated soil fertility management. Socio-demographic factors were not significant for motor pump adoption, and only mutual aid moderately influenced integrated soil fertility management. Economic factors like land tenure and income diversification were significant for motor pump adoption, but no economic factors were significant for integrated soil fertility management. Institutional factors such as access to credit and association membership were significant for the sustained adoption of both innovations.
Contamination & food safetyEconomicsPolicyHealthThe perceived influence of cost-offset community-supported agriculture on food access among low-income families
2022S.B. Jilcott Pitts, R.A. Seguin, J. Kolodinsky, E.H. Morgan, M.J. White, M. Sitaker, J.T. McGuirt, W. Wang, K.L. Hanson, A.S. Ammerman · UNC Libraries · United States
This study examined perspectives on food access among 53 low-income families with children participating in a cost-offset community-supported agriculture (CO-CSA) program across nine communities in the US states of New York, North Carolina, Washington, and Vermont. Focus groups revealed that while produce quantity was abundant and affordability was generally good, payment timing was a barrier for some, and unfamiliar foods and quick spoilage hindered acceptability. The study concluded that CO-CSA may facilitate increased access to fruits and vegetables, but perceptions of positive diet change may be limited by challenges in incorporating share pick-up into regular travel patterns and meal planning, with food waste concerns being particularly acute for families with constrained resources.

2022Ainsley C. McStay, S.L. Walser, Eric C. Sirkovich, Nicolas Perdrial, Justin B. Richardson · Journal of Environmental Quality · United States
This study evaluated portable X-ray fluorescence (pXRF) measurements of macronutrients, micronutrients, and toxic elements (As, Pb) in soils and plants from 10 urban community gardens across the eastern United States. It found that pXRF and traditional methods provided agreeable estimates for some elements (Mn, Cu, Zn, Pb) but not for macronutrients (Ca, K, P). While pXRF is an accurate tool for screening Mn, Cu, Zn, and Pb, macronutrients were poorly estimated in fruits, leaves, and roots, and genus-specific and garden-specific factors may be important for plant uptake models.
