The study found decreased sand content, pH, and dehydrogenase activity, while porosity, EC, BOD, COD, OC, available-NPK, SO4, Cl, and heavy metals (Mn, Fe, Zn, Cu, Ni, Cd, Pb, Cr) increased. Some parameters exceeded Indian standard permission limits, indicating contamination, with highest values observed in summer.
Contamination & food safetyHealthPeri-urban agricultureExpelled from the garden? Understanding the dynamics of green gentrification in Vancouver, British Columbia
2022Daniel Sax, Lorien Nesbitt, Shannon Hagerman · Environment and Planning E Nature and Space · Canada (Vancouver)
A case study of an urban farm in Vancouver, Canada, facing displacement due to redevelopment, revealed that urban residents engaged in urban greening can be both implicated in and impacted by green gentrification processes. The study highlighted the power dynamics farm members navigate to preserve land access and found that the farm's identity was co-opted by development agents as a branding tool. This research contributes to understanding the limitations of development processes in accounting for green gentrification risks.
Equity & displacementCommunityPolicyEconomicsHealthLegacy Lead in Urban Garden Soils: Communicating Risk and Limiting Exposure
2022Anna Paltseva, Zhongqi Cheng, Murray B. McBride, Maha Deeb, Sara Perl Egendorf, Peter M. Groffman · Frontiers in Ecology and Evolution · Global
This synthesis paper summarizes current scientific knowledge on lead (Pb) contamination in urban garden soils and provides clear recommendations for assessing actual health risks and limiting exposure. Urban garden soils often contain elevated levels of Pb, mainly from legacy sources, which is a main barrier for urban gardening. Amendments are noted as unreliable for treating contaminated soils to reduce risk, as they do not always make contaminants less harmful.

2022Ilona Liliána Birtalan, Imre Fertő, Ágnes Neulinger, József Rácz, Attila Oláh · BMC Public Health · Hungary
This study examined situational and engagement-related work difficulties for Community Supported Agriculture (CSA) farmers in Hungary, using interpretive phenomenology and semi-structured interviews. The research found that new modes of consumer-producer connectivity create novel issues for farmers, leading to three experiential themes: conflicted autonomy, the pressure of boxes, and social overload. These difficulties are rooted in the economic characteristics of alternative agriculture and structural conditions that require conflicting farmer roles. The study highlights the health and wellbeing costs of sustainable farming, noting that farmers often lack the time, experience, or skills for new producer-consumer connections.

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.

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.
