19 pages, Climate change threatens human health, the environment, and the global economy. Extreme temperatures, intensifying droughts, and changes in rainfall patterns and growing seasons are all results of a changing climate. Adaptations to climate change will need to be implemented in the agricultural sector to ensure the longevity and sustainability of the global supply of food. Community gardens are one part of the agricultural sector that provide access to fresh and affordable foods. The purpose of this study was to determine U.S. adults’ motivations for engagement and level of importance associated with climate-smart adaptations in community gardens. The study found respondents engaged in community gardens primarily for health and social reasons, and respondents assigned some level of importance to climate-smart adaptations in their community gardens. Environmental communicators should develop messaging that encourages adaptation in community gardens by emphasizing the risk of losing health or social-based benefits the gardens provide. The findings can inform effective communication strategies which encourage community gardens to prepare for climate change to ensure a sustainable supply of and access to fresh foods. Future research should explore the impact of rurality, food accessibility, and socioeconomic status on reasons for engaging in a community garden and associated level of importance related to climate-smart adaptations.
21 pages, Surging interest in urban agriculture has prompted cities across North America to adopt policies that give gardeners access to publicly owned land. However, if not carefully designed, these policies can exacerbate existing racial inequities. Drawing on theories of urban and environmental justice, we use a contextualized case comparison to explore the radical potential and practical constraints of garden land policies at two distinct institutions: the City of Minneapolis and the independently elected Minneapolis Park and Recreation Board. Based on participant observation, document review, and interviews with a range of policy actors, we argue that what appear to be minor, common-sense policy details systematically shape who benefits from the garden land policies, sometimes in surprising ways. Compared to the City, the Park Board goes substantially further in addressing racial equity. Furthermore, though both cases included public participation, we argue that the more intensive participation during the Park Board policy development process—particularly in determining the details—was pivotal in crafting a policy that reduced barriers to racial equity. The present study contributes to the growing scholarship on urban agriculture and environmental governance and offers concrete insights for actors working toward more just policies.
16 pages, Climate change is impacting the ecological, social and technological aspects of urban gardens. Gardens experience threats (e.g., water scarcity) but are also responding through adaptation strategies (e.g., selecting drought-resilient plants). A synthetic overview of how urban gardens are affected by climate change and responding to climate change is unclear. Here, we systematically reviewed articles and book chapters published in the last two decades (2000–2022) to illustrate the relationship between climate change and urban gardening. From 72 documents analyzed with Nvivo Software, we found that there has been an increase in academic publications. Universities from the US (14) and Germany (9) universities are the dominant producers. Evidence shows that climate change can have negative impacts on cities, people and urban food. Suggestions on how to build the adaptation capacity of urban gardens include collecting rainwater, changing plant selection, changing planting times, applying vegetative cover on the soil and other practices. For cities, community and allotment gardens are helpful for adaptation, mitigation and resilience. This includes the capacity to regulate the microclimate, to reduce urban heat island effects and to buffer urban floods, the power to capture carbon, the ability to create social networks and other socio-environmental benefits for urban climate planning.
17pgs, There is a lack of data on resources used and food produced at urban farms. This hampers attempts to quantify the environmental impacts of urban agriculture or craft policies for sustainable food production in cities. To address this gap, we used a citizen science approach to collect data from 72 urban agriculture sites, representing three types of spaces (urban farms, collective gardens, individual gardens), in five countries (France, Germany, Poland, United Kingdom, and United States). We answered three key questions about urban agriculture with this unprecedented dataset: (1) What are its land, water, nutrient, and energy demands? (2) How productive is it relative to conventional agriculture and across types of farms? and (3) What are its contributions to local biodiversity? We found that participant farms used dozens of inputs, most of which were organic (e.g., manure for fertilizers). Farms required on average 71.6 L of irrigation water, 5.5 L of compost, and 0.53 m2 of land per kilogram of harvested food. Irrigation was lower in individual gardens and higher in sites using drip irrigation. While extremely variable, yields at well-managed urban farms can exceed those of conventional counterparts. Although farm type did not predict yield, our cluster analysis demonstrated that individually managed leisure gardens had lower yields than other farms and gardens. Farms in our sample contributed significantly to local biodiversity, with an average of 20 different crops per farm not including ornamental plants. Aside from clarifying important trends in resource use at urban farms using a robust and open dataset, this study also raises numerous questions about how crop selection and growing practices influence the environmental impacts of growing food in cities. We conclude with a research agenda to tackle these and other pressing questions on resource use at urban farms.
14 pages, In recent years, “urban greening” has become a new keyword in urban policy and practice, used to describe a proliferation of urban quality of life and environmental sustainability initiatives including street trees, public parks, greenways, farmers' markets, green roofs, and LEED certification in design. The emerging critical literature on urban greening has highlighted important ways green's social and economic added value affects the political economy of contemporary greening and produces inequalities in access to real or perceived environmental goods. However, such research has only infrequently asked why and under what conditions naturalized understandings of green as “good” make it possible for such initiatives to add value in the first place. As a result, it offers only partial explanations of why green has the effects it has—for instance, increasing property values—and only very rarely questions the fundamental “good” of nature itself. I argue that integrating insights on green's naturalized social and economic value from a growing body of social-theoretical work across geography and the social sciences can complement political economic explanations for greening and provide new vantage points for critique.
10 pages., Article # 2FEA3, Via online journal., There are many potential advantages to collaborations between Extension and nonprofit organizations; however, it is unclear what factors contribute to a successful collaboration. We used an exploratory cross-comparative case study design to analyze four cases of highly successful Extension/nonprofit collaborations in one area in Florida. Using both deductive and inductive analysis processes, we identified several factors that contributed to the success of these partnerships: alignment of goals, longevity, informal adaptable partnering, relevant Extension agent background, delegation of tasks, marketability and fun, and relationship building. Exploration of these factors can inform future studies and has immediate, practical implications for Extension agents.
21 pages., Article #:2659, via online journal., Urban gardens are continuously negotiated, contested, and remade. One of the primary
ways that these spaces are negotiated is through the ways that communities self-organise to manage
them. Drawing on critical urban scholarship, this article explores the ways in which the dynamics of self-organisation in urban gardens both shape and are shaped by the spatial development of the sites. Reflecting on two cycles of participatory video-making with urban gardeners in Seville, Spain, the article specifically examines how the motivations of the gardeners and the issue of communication influence the dynamic relationship between self-organisation and the spatial development of gardens.
5 pages., via online journal, The growth of community gardens has created new opportunities for urban Extension personnel at a time when staffing resources continue to decline. To serve the integrated pest management (IPM) needs of community gardening populations, Extension educators in two urban counties developed an on-site program involving a demonstration kit and planning protocol that Extension educators, program staff, and master gardener volunteers can use to teach IPM. The program provides practical, research-based information to community gardeners, allows Extension to maintain a presence in urban centers, and provides outreach to audiences who may not have used Extension resources historically.
Conference paper, International European Forum, Innsbruck, Austria, February 5-9, 2018. Pages 271-283 in proceedings published in this journal., The increasing impact due to urban population’s food supply causes a series of negative externalities related to food production, transformation and transportation. FAO and other institutions are trying to integrate traditional models of food supply with alternative ones like Urban and Peri-Urban Agriculture (UPA). Defining the drivers that motivate the participation in different types of UPA could be useful to plan more participated and effective UPA development policies. Barcelona (Spain) hosts a number of cases representing different declinations that UPA can assume. This work aims at describing the differences in terms of motivations to enter the various typologies of Urban Agriculture (UA) in Barcelona. Data were collected through semi-structured interviews to 4 groups of users representing 3 of the most widespread models of UA initiatives in Barcelona (Allotment Gardens, Community Gardens, Pla Buits.) The results showed that participation in UA is mainly motivated by relational aspects and knowledge exchange and differences exist among the various UA models. Political reasons are mostly influencing the Community Gardeners while Pla Buits users’ mains motivations are related to socialising and Allotment gardeners are mainly motivated by environmental aspects. Differences in the participants’ demographic characteristics also emerged. Better targeted public policies contents and communication strategies for UPA development can thus be derived by the results obtained; to this end, recommendations have been provided. Further research should broaden the range of case studies and the sample size, in order to provide a more effective and comprehensive tool for tailoring UPA developing strategies to different contexts.
8 pages., Via online journal., With growing interest in food system solutions to address poor health outcomes related to preventable chronic diseases, organizations and researchers are examining the value of community gardens as interventions to promote individual and community health. Research suggests that participation in community gardens improves access to fresh, healthy foods and increases fruit and vegetable consumption. In addition to these physical benefits, research also documents a variety of social and communal benefits, by expanding social capital, stabilizing neighborhoods, and cultivating relationships. Unfortunately, most of these studies focus on a specific case, cross case, or intervention studies within a geographically specific locale. Learning lessons from successful community garden programs can be difficult because community gardens often rely on the synergy of a complex network of support agencies that assist in various technical and educational capacities. The purpose of the study was to demonstrate the use of a framework for program development and evaluation that stakeholders, including extension, can adopt to show program outcomes. The framework used a Delphi approach with a diverse panel of community garden stakeholders to reach consensus about program outcomes. The study demonstrated that the panel could reach consensus on a variety of short-, medium-, and long-term outcomes.
