In a natural wetland in the Mexico City Metropolitan Area — a major supplier of crops and flowers whose canals hold high concentrations of organochlorine (OC) and organophosphorus (OP) pesticides — bioaccumulation of these pesticides was studied in water hyacinth (Eichhornia crassipes), a plant considered a plague but suggested in the literature to have phytoremediation potential. In vivo bioaccumulation differences for OC pesticides were largely explained by their log Kow, while all OP pesticides showed bioaccumulation regardless of log Kow, and the higher bioaccumulation factors of some accumulated OC pesticides could not be explained by log Kow alone, suggesting passive transport into the plant. Translocation ratios showed water hyacinth to be an accumulating plant with phytoremediation potential for all the organophosphorus pesticides studied and some organochlorine pesticides, and an equation for free water surface wetlands with floating macrophytes showed pesticide removal by the wetland with room for improvement through better management.

Against a backdrop of high chronic-disease risk factor burden among Asian Americans, Native Hawaiians, and Pacific Islanders (AANHPIs) in the United States, the STRIVE Program funded four AANHPI community-based organizations (CBOs) to implement culturally adapted community gardens and farmers' markets aimed at increasing access to healthy foods. Key informant interviews were conducted with CBO staff to understand implementation processes and lessons learned; this abstract does not report specific outcome measures.

Nicholas Siewell, Madhavappallil Thomas · · United States (California)

A needs-assessment study followed by the establishment of a community garden in a neighborhood in Bakersfield, California (2015), collected survey and focus-group data from residents and garden participants to examine the garden's impact. Findings showed strong support for the garden and reported benefits to participants' physical and mental health, social capacities, and spiritual well-being at both the individual and neighborhood level. The authors present the project as an example of how university-community engagement initiatives can function as a macro-practice intervention framework for students, practitioners, and community leaders.

This study examined the philosophical background and historical development of the school garden movement in the USA to derive implications for Korean school gardening programs. The movement emerged from late 19th-century educational ideas, showing a process of formation (1891-1914), decline (post-WWI, 1950s), and revival (from 1990s). The revival was driven by efforts to address childhood obesity, nature-deficit, and improve academic achievements.

Research on farmworker food insecurity in the USA points out that food assistance providers often treat farmworkers' inability to afford healthy food as a lack of knowledge, reinforcing racialized assumptions that people of color do not know "good" food. This study argues that food security and healthy eating are not a matter of consumers making healthy "choices," but rather a matter of class-based and racial differences within the food system.

Marie-Ève Voghel Robert · · Canada (Montréal)

This research internship, conducted in Montreal-Nord, Canada, during winter and spring 2013, aimed to understand the potential of urban agriculture from the perspective of both gardeners and non-gardeners. Through five group interviews, participants emphasized the essential role of human and social relationships in collective gardening projects, beyond just food production. They also proposed integrating collective gardening with other projects to create a comprehensive food system in Montreal-Nord, enhancing project longevity and food accessibility.

This study examines the early stages of the urban farming movement in Louisville, Kentucky, considering its relation to land use, segregation policies, obesity, and food security. While the urban farm movement is largely a success in New York, it is suggested that in Louisville, Chicago, and Detroit, where trans-fat bans did not succeed, the urban farm movement may be the primary means of addressing malnutrition in the form of obesity.

This study investigated health motivations for purchasing local foods among consumers in the Southeastern United States. It analyzed the effects of specific health variables, focusing on family illness incidences of six diseases (heart disease, diabetes, obesity, back/joint pain, Alzheimer/dementia, and cancer), on local food buying behavior. Using a binary probit model, findings indicated that a family history of cancer and obesity were statistically significant factors in purchasing local foods. Other important factors included a higher physical activity level, following a special diet, and the availability of farmers' markets.

A preliminary analysis of Chicago's 49th Ward, the first participatory budgeting experiment in the United States, examined whether it resulted in different budgetary priorities and met social justice outcomes. Citizens chose projects classified as low priority by research literature, and while there was no clear pattern of projects only in affluent areas, geographic clustering was evident. Select areas received projects like community gardens, while others were limited to infrastructure repairs, indicating mixed social justice outcomes.
