Unexpected effects of urban food activism on community and human wellbeing

Participation in urban agriculture conducted through community gardens and allotments is known for its benefits to physical and mental health. Due to the recognition of these benefits, which include reduction of stress, depression and anxiety, such participation is increasingly being prescribed as a non-medical health intervention. Community gardens have the added advantage of immersion into a community, without the often-long waiting lists and level of commitment involved in allotment tenancies. What has not been explored is the demanding nature of the commitment required by volunteer coordinators, and ironically, the negative effects it can have on their wellbeing. In a study of food activism in Aberdeen, UK, we conducted 21 semi-structured interviews with participants from a range of bodies involved in the city's food growing projects. From the spectrum of food growers, we found that volunteer coordinators of community gardens experienced the greatest burdens on their time and wellbeing, with their demanding multi-functional roles leading to fatigue and feelings of over-commitment. Other problems encountered by community gardeners were over-reliance on grant funding and the disproportionate impacts of COVID closures on vulnerable groups. Policy interventions are required to reduce dependency on competitive grant funding and to support both coordinators and the long-term sustainability of community gardens.

Hands-on-ground in a new country: a community-based participatory evaluation with immigrant communities in Southern Alberta

Immigrants experience a high risk of mental health deterioration following settlement in Canada. Immigrant communities benefit from health-promoting interventions that stimulate social inclusion and belonging as protective factors. In this context, community gardens have been recognized as interventions that promote healthy behaviours, place attachment and belonging.This article summarizes our experience conducting a community-based participatory evaluation (CBPE), engaging community stakeholders in planning, implementing and evaluating a community garden for immigrants. We conducted a CBPE to provide relevant and timely feedback to inform programme adaptation and development. Participants, interpreters and organizers were engaged through surveys, focus groups and semi-structured interviews. Participants expressed a range of motivations, benefits, challenges and recommendations. The garden was a place that fostered learning and promoted healthy behaviours, including physical activity and socialization. However, there were challenges in organization and communication with participants. Findings were used to adapt the activities to immigrants' needs and expand the programming of collaborating organizations. Stakeholder engagement facilitated capacity building and direct use of findings. This approach may catalyse sustainable community action with immigrant communities.

Community gardens and urban agriculture: Healthy environment/healthy citizens

Studies are showing that urban community gardening can improve people's psychological and physiological health in myriad ways. Community gardens increase social capital, provide opportunities for altruism, and create accessible and sustainable food sources in urban environments. The purpose of this study was to explore the mental, social, and physical health benefits of participation in an urban community garden in Edmonton, Canada. A focused ethnography was conducted with surveys and semi-structured interviews. Surveys were sent to volunteers and customers of the Green and Gold Garden (GGG). This was followed by focus group interviews with eight volunteers and four customers. The interview format comprised open-ended questions that encouraged participants to share their perceptions of the health and well-being benefits from being at the GGG. Data were coded via inductive coding, and subsequently categorized into themes via an iterative, reflective process. Four health-related themes were generated from thematic analysis: physical health, social health, mental/emotional health, and connection to the global community. Spending time at the GGG improved the respondents' mental health, even during the COVID-19 pandemic, as they reported feelings of altruism, serenity, and connection with nature. Their social health was improved through gathering with other garden members in a sheltered urban green space within the city limits. This study supports the idea that participation in an urban community garden confers health benefits and engenders a greater awareness of, and appreciation for, the local environment and expands one's scope of care to incorporate planetary health.

Expanding Community Engagement and Equitable Access Through All-Abilities Community Gardens

Community gardens accessible to people of all abilities provide affordable fresh produce for people with disabilities (PwD) who frequently experience food inequity and related health risks. The objective of this project was to enable 9 community gardens in southern New Jersey to welcome PwD and encourage their use through inclusive designs and practices. Postprogram surveys and a half-day group collaboration session demonstrated the desire of PwD to engage in inclusive gardens, the potential for increased social connections and produce consumption among PwD, and the challenge of limited resources in maintaining community gardens.

The effects of COVID-19 on Central Florida's community gardens: lessons for promoting food security and overall community wellbeing

For quite some time, food systems scholars, public health workers, and food justice activists have recognized structural problems in the global food system that can cause food insecurity and inequitable access to nutritious foods. The COVID-19 pandemic and the accompanying disruption in food supply chains (FSCs) exposed these problems and raised questions about how community gardening and urban agriculture might offer some solutions. In this article, we examine the effects of the pandemic on the operations of community gardens in Central Florida and the attempts of these gardens to address the disruption in food supplies in their local communities. We do so by using data drawn from two research strategies employed by the members of University of South Florida's Urban Food Sovereignty Group: (1) a survey conducted in 2021 of 45 leaders of community gardens throughout the Central Florida region; and (2) participation in the meetings and activities of a coalition of community gardens based in Tampa, Florida, from 2019 to 2022. Results reveal that although most community gardens in Central Florida were forced to change their routines in various ways (e.g., limiting the number of workers or volunteers who could work at the garden at the same time, or delivering workshops and education programs online instead of in-person), some gardens were able to maintain their regular operations and even reported increases in their membership or participation during the pandemic. Many community garden leaders also recognized the positive effect that community gardening seemed to have on their gardeners' mental health, noting that their gardens became places of refuge for gardeners who sought safe, outdoor spaces, to relieve stress and interact with their neighbors. These same leaders also observed the effect of the pandemic on residents' access to quality food, and intensified their efforts to provide more fresh food to pantries and traditional emergency food outlets. Survey respondents also shared important lessons they learned from the pandemic by suggesting that community gardens establish clear emergency protocols, use existing resources more efficiently, continue their educational programs, and strengthen their communications and cooperation with other gardens and actors in local food supply chains in order to ensure food security. We conclude by suggesting that one of the best ways that local communities can avert future food crises and strengthen their resilience is to root themselves more firmly in the principles of food sovereignty so they can sustain themselves when commercial FSCs are disrupted.

A Pilot Study Exploring Practices that Support the Longevity of Community Gardens Supported by Religious Organizations

Current food production methods in the United States (US) contribute to environmental degradation as well as food insecurity. Food production by means of community gardens has the potential to reduce the deleterious effects of current production methods. However, many community gardens face challenges that hinder their longevity, thereby reducing the likelihood of the support they might provide for environmentally sustainable food production and decreased food insecurity for community members. Researchers conducted a literature review regarding best practices for community gardens, and used ethnographic research methods to inform a culturo-behavioral systems analysis using the Total Performance System and matrix (systems interdependency) analysis to better understand the cultural practices of two established community gardens in the southwest region of the US. The results of the analyses are presented in terms of recommendations to support each community garden's sustainability. Recommendations regarding future research include environmental manipulations to identify functional relations and potential outcome measures for improving the longevity of community gardens.

Community Gardens: A Catalyst for Community Change

Community gardens are increasing in popularity and are associated with extensive physical and mental health benefits, increased access to fresh produce, and increased social connections. However, evidence is primarily from research in urban and school settings, and little is known about the role of community gardens in rural settings as part of policy, systems, and environmental (PSE) changes to promote health. This study explores the implementation of community gardens as part of an obesity prevention project, titled Healthier Together (HT), in five rural Georgia counties with limited food access and high obesity prevalence (>40%) using a mixed-methods research design that included data from project records, a community survey, interviews, and focus groups with county coalition members. Nineteen community gardens were implemented across five counties, 89% distributed produce direct to consumers, and 50% were integrated into the food system. Few (8.3%) of the survey respondents (n = 265) identified gardens as a food source, but 21.9% reported using an HT garden in the past year. Themes emerging from interviews (n = 39) and five focus groups suggested community gardens were a catalyst for broader community health change by increasing awareness of the value and absence of healthy food and generating excitement for future PSE initiatives to more comprehensively address food and physical activity access. Practitioners should consider placement of rural community gardens to optimize access to and distribution of produce as well as communication and marketing strategies to increase engagement and leverage gardens as gateways for PSE approaches to improve rural health.

Practices of Care and Relationship-Building: A Qualitative Analysis of Urban Agriculture's Impacts on Black People's Agency and Wellbeing in Philadelphia

Gardens and farms provide individuals and communities with access to affordable, nutritious, and culturally significant foods. There is a rich body of literature unpacking the connections between Black urban growing and agency, freedom, resistance, and care. However, spirituality remains one aspect of health and wellbeing that has not been studied extensively in relation to agriculture. The main goal of this study was to conduct focus groups with Philly-based growers to understand the self-determined impacts of urban agriculture on health, agency, and wellbeing. The secondary goal of this work was to determine if these impacts differ by race. I apply a collective agency and community resilience theoretical framework to this study. This framework offers a model to understand agriculture as a way for communities to become self-determined, self-reliant, and self-sustained. For this study exploring the impacts of urban agriculture on health, there were three eligibility criteria. Participants had to be at least 18 years old, identify as Black or White, and have grown food in a garden or farm in Philadelphia. I hosted six race-specific focus groups at Bartram's Garden in Southwest Philadelphia. The audio recordings were transcribed, and the full transcripts were coded using open and axial coding methods and a "key concepts" framework. We also employed several methods of triangulation to help ensure the credibility and validity of the findings. Four major themes emerged from the data: growing as a demonstration of agency and power, growing as a facilitator of body-mind wellness, community care and relationship-building, and deepened spiritual connection and interdependence. There were both similarities and differences in the impacts of urban agriculture by race. Across the six focus groups, people talked about concepts related to community care and relationship-building as being major benefits of growing food. In both groups, people also brought up significant issues and barriers around land security. Mentions of spirituality appeared more frequently and more emphatically in the Black focus groups. Black focus groups were more likely to discuss the collective impacts of agriculture, while White participants were more likely to discuss the impacts on themselves as individuals. The findings of this focus group study point to some key domains through which agriculture impacts the health of farmers and growers in Philadelphia.

Enablers and Barriers of Community Garden Use in New Orleans, Louisiana: An Environmental Assessment and Qualitative Analysis

PURPOSE

To explore factors associated with community garden use.

APPROACH

Environmental assessment of community gardens and semi-structured interviews.

SETTING

New Orleans, Louisiana.

PARTICIPANTS

10 community gardens (environmental assessment), 20 community members (including garden users and non-users) and garden administrators (qualitative interviews).

METHOD

Gardens were assessed based on (1) accessibility, (2) information, (3) design, (4) cleanliness, (5) walkability, (6) parking, and (7) noise. Semi-structured interviews took place over Zoom; transcribed interviews were analyzed using thematic analysis.

RESULTS

Gardens assessed in the environmental assessment ranked high in design and cleanliness but low on accessibility and information availability. Salient themes from the qualitative interviews include skill-building, access to fresh foods, and increased social engagement as enablers of community garden participation, with availability of information and time as both potential enablers of, or barriers to, participation. Community members perceived that gardens could increase fresh food access, while administrators believed that it is not possible for community gardens to produce enough food to create community-wide impact, highlighting instead the importance of the social aspects of the garden as beneficial for health.

CONCLUSION

Community gardens should improve garden physical accessibility and information availability to incentivize use. Community gardens are valued as means for skill-building and social engagement. Future research should prioritize investigating the association between the social aspects of participating in community gardens and health outcomes.

School Gardening and Health and Well-Being of School-Aged Children: A Realist Synthesis

School environments can create healthy settings to foster children's health and well-being. School gardening is gaining popularity as an intervention for healthier eating and increased physical activity. We used a systematic realist approach to investigate how school gardens improve health and well-being outcomes for school-aged children, why, and in what circumstances. The context and mechanisms of the specific school gardening interventions (n = 24) leading to positive health and well-being outcomes for school-aged children were assessed. The impetus of many interventions was to increase fruit and vegetable intake and address the prevention of childhood obesity. Most interventions were conducted at primary schools with participating children in Grades 2 through 6. Types of positive outcomes included increased fruit and vegetable consumption, dietary fiber and vitamins A and C, improved body mass index, and improved well-being of children. Key mechanisms included embedding nutrition-based and garden-based education in the curriculum; experiential learning opportunities; family engagement and participation; authority figure engagement; cultural context; use of multi-prong approaches; and reinforcement of activities during implementation. This review shows that a combination of mechanisms works mutually through school gardening programs leading to improved health and well-being outcomes for school-aged children.

Acceptability and Feasibility of Community Gardening Interventions for the Prevention of Non-Communicable Diseases among Indigenous Populations: A Scoping Review

Compared with non-Indigenous populations, Indigenous populations experience worse health across many outcomes, including non-communicable diseases, and they are three times more likely to live in extreme poverty. The objectives were to identify (1) the content, implementation, and duration of the intervention; (2) the evaluation designs used; (3) the outcomes reported; and (4) the enablers and the challenges. Using the PRISMA-ScR guidelines, a search of research databases and grey literature was conducted. Seven studies met the inclusion criteria. Papers reported on acceptability, nutrition knowledge, fruit and vegetable intake, self-efficacy, motivation, and preference concerning fruit and vegetable, diet, and gardening. No study measured all outcomes. All papers reported on acceptability, whether implicitly or explicitly. The evaluation used mostly pre- and post-intervention assessments. The effect of gardening on nutrition and gardening knowledge and fruit and vegetable intake was inconclusive, and was related to a general lack of robust evaluations. Applying the He Pikinga Waiora Framework, however, revealed strong evidence for community engagement, cultural centeredness, integrated knowledge translation and systems thinking in increasing the acceptability and feasibility of gardening in Indigenous communities. Despite environmental challenges, the evidence signaled that gardening was an acceptable intervention for the Indigenous communities.

A Vanishing Food Infrastructure: The Closure of Food Outlets in Flint in a Pandemic Era

Most food access studies focus on large cities, examine traditional grocery stores, and only consider operational food outlets. This siloed approach exposes a gap in food access literature. Therefore, as a part of our assessment of Flint’s food landscape, we examined closed food outlets in the city and surrounding townships. We investigated the relationship between the racial composition of census tracts and the number and type of defunct food outlets identified. We used Data Axle to collect and verify data on open and closed food outlets between September 2020 and December 2021. We made a final verification of the food outlet closures in June 2022. We used ArcGIS 10.8.1 and SPSS Version 28 to map and analyze the data. We used negative binomial regression models to determine differences in the likelihood of having an additional closed food outlet in census tracts with low and high percentages of Black residents. We also investigated the relationship between a census tract’s median income and the likelihood of having an additional closed food outlet. There were 173 closed food outlets; 81 were in Flint, and 92 were in surrounding townships. The most frequently closed food outlets were restaurants; they accounted for 45.1% of the closures. The mean number of closed food venues in census tracts where less than 40% of the residents were Black was 1.5. The mean was similar in census tracts where 40% or more of the residents were Black; it was 1.6. This difference was not significant. However, the median income of a census tract was a significant predictor of the likelihood of having an additional closed food outlet. Every one-thousand-dollar increase in median income resulted in a 2% less likelihood of having an additional closed food outlet. The results of this study show that there is more to the food landscape of a city than its operational food outlets. Focusing exclusively on active food outlets does not accurately depict a city's food infrastructure.

Connecting to nature through community engaged scholarship: Community gardens as sites for collaborative relationships, psychological, and physiological wellbeing

Community gardens are recognized as being associated with a range of benefits for participants that include enhanced outcomes in physical and affective domains and community building. The purpose of this study was to research the impact of the New South Wales Royal Botanic Gardens (RBG) Community Greening (CG) program and to inform the ongoing development of this community outreach program. The organic community partnerships inherent in the design and the relationships between the Community Greening program participants and researchers is examined through the lens of Community Engaged Scholarship (CES). Over a seven-month period, the CG team implemented a community garden development program in six sites. Mixed-method research on the impact of the program found that the community gardening participants experienced positive changes in physical activity, psychological wellbeing and motivation for social engagement, and these outcomes were facilitated as a result of their relationships with members of the CG team. This paper examines how such programs, when explicitly framed as CES, could assist in consolidating nature-based community health and wellbeing programs and further legitimize community partnerships in development of community garden and green spaces as academically sound investigation and socio-economically justified activity. Expansion of this nature-based collaboration model may also enhance community engagement in green exercise, psychological wellbeing and community cohesion, and in turn support advocacy for greener environments locally, regionally and nationally.

Nature-Based Equity: An Assessment of the Public Health Impacts of Green Infrastructure in Ontario Canada

The built environment is a physical determinant of health essential to the planning and development of a more equitable society. Communities face growing challenges due to environmental stressors such as climate change, with vulnerable communities experiencing a disproportionate burden of adverse health outcomes. The interdependencies between urban planning and public health outcomes are inextricable, with respect to improving access to healthier built environments for vulnerable and marginalized groups. Widespread implementation of nature-based solutions, such as green infrastructure, provides a multi-functional strategy to support sustainable development, increase climate resilience, enhance ecological connectivity, and create healthier communities. A Health Equity Impact Assessment presents the findings of a participatory research study utilizing key informant interviews of public health unit professionals (eight) and a survey of green infrastructure volunteers and workers (36) on the impact of green infrastructure on individual and community mental and physical well-being, service use, and perceived unmet needs, using Ontario, Canada as a case study. Study findings indicate that where green infrastructure is both productive and publicly accessible, the benefits were significant for vulnerable populations. These benefits include increased social connectivity, skills development, and food security. Green infrastructure could be a viable strategy to address environmental stressors, improve health equity, and support localization of the UN Sustainable Development Goals (SDGs).

Community gardens and wellbeing amongst vulnerable populations: a thematic review

The aim of the thematic review is to document the effects of community gardens on wellbeing amongst vulnerable populations. We searched for articles published between 1980 and 2017 in major databases resulting in the inclusion of 51 articles. Vulnerable populations included, amongst others, ethnic minorities and refugees, socioeconomically disadvantaged neighbourhoods or low-income or food insecure families. Our findings suggest that community garden participation may have a positive impact on physical health, such as reducing body weight and hypertension, and increasing physical activity and food knowledge. However, findings relating to community gardens and their potential to enhance food security were inconsistent. Furthermore we found that community gardens can have a positive influence both at the individual level (i.e. self-esteem, independence, personal control, etc.), particularly for refugees; the relational and social level (i.e. relationships, social connections, community and neighbourhood). Community garden participation have the potential to enhance wellbeing amongst vulnerable populations. However, two articles in our review presented potential food safety concerns related to community gardens, indicating that, particularly in urban settings, attention must be given to minimizing potential food safety concerns, e.g. by using raised garden beds. Based on this review, we recommend that further research and evaluation on non-US-based community gardens is carried out, as community gardens are practiced globally but there is little research to document the effects of community gardens on wellbeing amongst vulnerable populations outside of the USA.

Community Garden Initiatives Addressing Health and Well-Being Outcomes: A Systematic Review of Infodemiology Aspects, Outcomes, and Target Populations

Previous research has suggested that activities such as community gardens could offer a wide range of health benefits. The aim of the article is to systematically review the available literature to analyse the magnitude of the phenomenon, the geographical distribution, and the main characteristics in terms of health outcomes and target populations. The search addresses the question whether the activity in community gardens improves health and well-being outcomes of individuals. From the total amount of 7226, 84 selected articles showed that:(1) up to 50% are published by U.S. universities or institutions; (2) up to 44% of the studies considered “community gardens” as the main activity of the research focus; (3) one-third of the studies included adults; (4) almost 25% of the studies used “general health” as the main outcome when investigating the benefits of community gardens; (5) the percentage of studies that achieved their outcomes was heterogeneous among the different health dimensions. In conclusion, while a certain degree of heterogeneity in the used definition and outcome still exist, community gardens may be a viable strategy for well-being promotion in terms of psychological, social, and physical health and may be considered as an innovative urban strategy to promote urban public health.

Framing Food Access: Do Community Gardens Inadvertently Reproduce Inequality?

BACKGROUND

Alternative food programs have been proposed as solutions to food insecurity and diet-related health issues. However, some of the most popular programs-farmers markets and community-supported agriculture-overwhelmingly serve White and upper-middle-class individuals, exacerbating food security and health disparities. One explanation for the mismatch is the way in which alternative food programs are framed: Language used to encourage participation may reflect priorities of upper-middle-class and White populations who create and run these programs while lacking resonance with food-insecure populations. This literature, however, lacks consideration of how lower-cost, more participatory programs-community gardens-are framed. We therefore explore the framing of community gardens through a quantitative content analysis of the descriptions, missions, and goals provided by community garden managers across Minnesota (N = 411).

RESULTS

Six frames were consistently present in the community garden statements: greater good, community orientation, healthy food access, food donation, self-empowerment, and symbolic food labels. Greater good and community orientation were significantly more likely to be used than any other frames.

CONCLUSIONS

Taken together, our findings suggest that community gardens may be welcoming toward a diversity of participants but still have room to improve the inclusivity of their frames. The common use of a community orientation suggests the unique ability of community gardens among alternative food programs to benefit Black, Latino, and working-class populations. However, the most common frame observed was "greater good," suggesting one mechanism through which community gardens, like other types of alternative food programs, may be reproducing inequality through alienation of food-insecure populations.

Positive aging benefits of home and community gardening activities: Older adults report enhanced self-esteem, productive endeavours, social engagement and exercise

Objectives

This study examined relationships between home and community gardening and older adults' self-reported psychosocial and physical well-being, attitudes to aging relative to gardening activities and benefits of membership to a gardening group.

Methods

A survey addressing (a) demographic characteristics, (b) gardening interests and sentiments, (c) activities, (d) benefits, (e) self-rated health and quality of life and (f) attitudes to aging was administered online and via mail-out.

Results

Participants, 331 gardeners aged 60-95 years from Australia, reported numerous benefits from leisure gardening. According to multiple regression analysis, Restoration and Physical benefits were the strongest explanatory variables of participants' positive aging self-perceptions. Members of gardening groups reported significantly more social and physical benefits than non-members.

Conclusion

The current study provides support for promoting positive aging through gardening. Regardless of 'doing' gardening or simply 'being' in the garden, having contact with nature was key to attaining positive therapeutic benefits for this sample.

Translating Urban Walkability Initiatives for Older Adults in Rural and Under-Resourced Communities

The built environment can promote physical activity in older adults by increasing neighborhood walkability. While efforts to increase walkability are common in urban communities, there is limited data related to effective implementation in rural communities. This is problematic, as older adults make up a significant portion of rural inhabitants and exhibit lower levels of physical activity. Translating lessons from urban strategies may be necessary to address this disparity. This review examines best practices from urban initiatives that can be implemented in rural, resource-limited communities. The review of the literature revealed that simple, built environment approaches to increase walkability include microscale and pop-up infrastructure, municipal parks, and community gardens, which can also increase physical activity in neighborhoods for urban older adults. These simple and cost-effective strategies suggest great potential for rural communities.

Brownfields to Greenfields: Environmental Justice Versus Environmental Gentrification

Gentrification is a growing concern in many urban areas, due to the potential for displacement of lower-income and other vulnerable populations. This process can be accelerated when neighborhood "greening" projects are undertaken via governmental or private investor efforts, resulting in a phenomenon termed environmental or "green" gentrification. Vacant land in lower-income areas is often improved by the existing community through the creation of community gardens, but this contributes to these greening efforts and paradoxically may spur gentrification and subsequent displacement of the gardens' stewards and neighbors. "Is proximity to community gardens in less affluent neighborhoods associated with an increased likelihood of gentrification?" Using Brooklyn, New York as a case study, we examined this question using Geographic Information Systems and two spatial methods: a census block group proximity analysis, and a hot spot analysis, to determine the potential impact of proximity to community gardens in lower-income areas. The results of the analyses suggest that proximity to community gardens is associated with significant increases in per capita income over the five years study period, which is indicative of areas undergoing gentrification. This has implications for environmental justice because existing lower-income residents are likely to be displaced after their community is improved environmentally.

Best practices for community gardening in a US-Mexico border community

Minority communities such as those on the US-Mexico border are placed at disproportionate high risk for child and adult obesity, diabetes and cardiovascular diseases. A built environment characterized by an arid desert climate, lack of access to healthy foods, barriers to increasing physical activity, cultural and community norms which deter healthy eating and sustainable food production, shape obesity-related health disparities in these communities. Three pilot community gardens (implemented by two local governmental organizations and one community-based organization) were funded through the local Healthy Eating Active Living (HEAL) initiative in El Paso, Texas, and Las Cruces and Anthony, New Mexico (US-MX border communities with high obesity rates) in order to encourage healthy lifestyles among families in the region. A mixed-methods evaluation (n = 223) examined the implementation process, immediate outcomes and best practices of implementing and sustaining community gardens in these minority binational communities. In addition to nutrition-related outcomes, the potential for psychosocial outcomes from participating in community and school garden projects were observed. The best practices in relation to (i) assessing community norms related to growing food, (ii) increasing access to land and water for community/school gardening and (iii) enhancing social support for gardening are discussed. The implications of these best practices for obesity prevention and implementing community gardens in a minority US-MX border community characterized by cultural, geographical and socioeconomic barriers are examined.

Effects of greening and community reuse of vacant lots on crime

The Youngstown Neighborhood Development Corporation initiated a 'Lots of Green' programme to reuse vacant land in 2010. We performed a difference-in-differences analysis of the effects of this programme on crime in and around newly treated lots, in comparison to crimes in and around randomly selected and matched, untreated vacant lot controls. The effects of two types of vacant lot treatments on crime were tested: a cleaning and greening 'stabilisation' treatment and a 'community reuse' treatment mostly involving community gardens. The combined effects of both types of vacant lot treatments were also tested. After adjustment for various sociodemographic factors, linear and Poisson regression models demonstrated statistically significant reductions in all crime classes for at least one lot treatment type. Regression models adjusted for spatial autocorrelation found the most consistent significant reductions in burglaries around stabilisation lots, and in assaults around community reuse lots. Spill-over crime reduction effects were found in contiguous areas around newly treated lots. Significant increases in motor vehicle thefts around both types of lots were also found after they had been greened. Community-initiated vacant lot greening may have a greater impact on reducing more serious, violent crimes.

Maize Germplasm Conservation in Southern California's Urban Gardens: Introduced Diversity Beyond ex situ and in situ Management

Contemporary germplasm conservation studies largely focus on ex situ and in situ management of diversity within centers of genetic diversity. Transnational migrants who transport and introduce landraces to new locations may catalyze a third type of conservation that combines both approaches. Resulting populations may support reduced diversity as a result of evolutionary forces such as genetic drift, selection, and gene flow, yet they may also be more diverse as a result of multiple introductions, selective breeding and cross pollination among multiple introduced varietals. In this study, we measured the amount and structure of maize molecular genetic diversity in samples collected from home gardens and community gardens maintained by immigrant farmers in Southern California. We used the same markers to measure the genetic diversity and structure of commercially available maize varieties and compared our data to previously reported genetic diversity statistics of Mesoamerican landraces. Our results reveal that transnational dispersal creates an opportunity for the maintenance of maize genetic diversity beyond its recognized centers of diversity.

African American and Latino low income families' food shopping behaviors: promoting fruit and vegetable consumption and use of alternative healthy food options

Minority families often reside in neighborhoods with few supermarkets or alternative healthy food options (e.g., farmers markets, community gardens), making fresh produce difficult to obtain. This qualitative study identified factors influencing fruit and vegetable shopping and use of alternative healthy food options. Forty-eight minority women with children completed interviews regarding food shopping habits and use of and attitudes toward alternative healthy food options. Interviews were subjected to thematic analysis. Produce shopping was motivated by costs and family preferences. For African American women, poor cooking skills restricted the variety of fruits and vegetables purchased. Latinas were receptive to alternative healthy food options, but did not use them because these sources were inconvenient. African American women were not receptive to them. Improving cooking skills and perceptions of acceptable foods may be as important as increased access to promote greater consumption of fruits and vegetables.

Lead in New York City community garden chicken eggs: influential factors and health implications

Raising chickens for eggs in urban areas is becoming increasingly common. Urban chickens may be exposed to lead, a common urban soil contaminant. We measured lead concentrations in chicken eggs from New York City (NYC) community gardens and collected information on factors that might affect those concentrations. Lead was detected between 10 and 167 μg/kg in 48 % of NYC eggs. Measures of lead in eggs from a henhouse were significantly associated (p < 0.005) with lead concentrations in soil. The association between soil and egg lead has been evaluated only once before, by a study of a rural region in Belgium. In our study, the apparent lead soil-to-egg transfer efficiency was considerably lower than that found in Belgium, suggesting that there may be important geographic differences in this transfer. We developed models that suggested that, for sites like ours, lead concentrations in >50 % of eggs from a henhouse would exceed store-bought egg concentrations (<7-13 μg/kg; 3 % above detection limit) at soil lead concentrations >120 mg/kg and that the concentration in one of six eggs from a henhouse would exceed a 100 μg/kg guidance value at soil lead concentrations >410 mg/kg. Our models also suggested that the availability of dietary calcium supplements was another influential factor that reduced egg lead concentrations. Estimates of health risk from consuming eggs with the lead concentrations we measured generally were not significant. However, soil lead concentrations in this study were <600 mg/kg, and considerably higher concentrations are not uncommon. Efforts to reduce lead transfer to chicken eggs and associated exposure are recommended for urban chicken keepers.
