Title: Does Urban Agriculture Improve Food Security? Examining the Nexus of Food Access and Distribution of Urban Produced Foods in the United States: A Systematic Review
The aim of our review is to critically analyze the urban agriculture and urban food systems literature in order to understand the impact of urban-produced foods on community food security. We examine the role of city planning, food policy, and civic engagement in creating spaces for urban agriculture in cities across the United States, and whether (and how) these spaces promote food justice and food security. Bringing together multidisciplinary literature on access to urban agriculture and the distribution of urban-produced foods in a thematic, systematic review, we point out gaps in the academic research that would benefit from further study. The review integrates academic literature generated from Web of Science searches with gray literature identified through Google Alerts. We find that while there is a strong focus on elucidating the multiple benefits of urban agriculture, there are few studies that robustly measure the impact of urban farms on improving food security in low-income communities. Much of the literature is theoretical, focused on the production potential of urban agriculture, while more work is needed to understand and overcome barriers to access and distribution among communities in need. We conclude with a set of recommendations for researchers, practitioners, and policymakers who seek to create spaces in cities for food justice, equity, access, and sovereignty.  more » « less

  1. Despite extensive literature on the socio-cultural services of urban open spaces, the role of food-producing spaces has not received sufficient attention. This hampers advocacy for preserving and growing urban agricultural activities, often dismissed on justifications that their contributions to overall food supply are negligible. To understand how the social benefits of urban agriculture have been measured, we conducted a systematic review of 272 peer-reviewed publications, which drew on insights from urban agriculture sites in 57 different countries. Through content analysis, we investigated socio-cultural benefits in four spheres: engaged and cohesive communities, health and well-being, economic opportunities, and education. The analysis revealed growth in research on the social impacts of gardens and farms, with most studies measuring the effects on community cohesion and engagement, followed by increased availability and consumption of fruits and vegetables associated with reduced food insecurity and better health. Fewer studies assessed the impact of urban farming on educational and economic outcomes. Quantifying the multiple ways in which urban agriculture provides benefits to people will empower planners and the private sector to justify future investments. These findings are also informative for research theorizing cities as socio-ecological systems and broader efforts to measure the benefits of urban agriculture, in its many forms.

  2. Abstract 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.

  3. Food sovereignty, a framework focused on systemic change in the food system that accounts for food access, food justice, and food security, is an important driver of community wellbeing. However, the complex determinants of food sovereignty are not fully understood. Interdisciplinary assessments of food systems are needed to establish the impact of socioeconomic status, race, gender, and other social identities on food access. Understanding the goals and lived experiences of diverse communities and community members is critically important to advancing research on the sociology of food and agriculture. Drawing from community interviews addressing local food systems in six different communities in Washington's Upper Yakima River Basin, a qualitative assessment of expert perspectives on local and regional food systems illuminates perceived connections between food sovereignty and wellbeing. Findings suggest that food access and dependence on local agriculture varies across and within communities. Additionally, we find that agriculture is undergoing social, economic, and political transitions that may have immense community impacts moving forward. Given the diverse array of both agricultural and recreational economies in the study site, qualitative data informs our understanding of stakeholder perceptions at multiple levels of the food system. The implications of these findings lead to a forward‐looking discussion of linkages between food dimensions and other variables that impact local and regional wellbeing.

  4. Abstract Urban agriculture has significant potential to address food security and nutritional challenges in cities. However, water access for urban food production poses a major challenge in the face of climate change and growing global freshwater scarcity, particularly in arid and semi‐arid areas. To support sustainable urban food production, this study focuses on a hybrid urban water system that integrates two important alternative water resources: a decentralized system of rainwater harvesting (RWH) and a centralized reclaimed water system. A new spatial optimization model is developed to identify the best investment strategy for deploying these two alternative water infrastructures to expand urban food production. The model is applied to the case study in Tucson, Arizona, a semi‐arid city in U.S. Southwest, to address food deserts in the region. Results show that 72%–96% of the investment is allocated to rainwater tanks deployment across all investment scenarios, with the proportion of investment in rainwater harvesting increasing as total investment rises. However, rainwater contributes only about 18%–27% of the total food production. The results of our case study indicate that expanding the reclaimed water network is more effective for urban food production and is also more cost‐efficient compared to implementing rainwater tanks. The new model can be applied to other regions, taking into account factors such as crop types, climate, soil conditions, infrastructure configurations, costs, and other site‐specific variables. The study provides valuable insights for planning urban water systems that incorporate alternative water sources under different investment scenarios.

  5. The United States Department of Agriculture (USDA) has utilized the term food desert to highlight regions within low-income communities located far from fresh and healthy sources of food such as supermarkets and farmers markets. Most research on food deserts has revolved around urban areas, which bring about other considerations such as sidewalks, pedestrian access, rideshares, and public transportation, typically not viable options in rural regions. Rural food insecurity is also a problem in North Carolina. Utilizing data provided by the United States Department of Agriculture’s Food Access Atlas, this paper explored if and to what extent rural food insecurity exists, with findings showing 1) a higher percentage of people living in rural areas live in food insecurity compared to non-rural areas 2) counties in the eastern part of the state are more prone to food insecurity and 3) racial, ethnic minorities, as well as the young (age under 17), are more subjected to food insecurity compared to the majority and older cohorts. This research highlights the need for a rigorous and comprehensive understanding of rural food security that transcends the economic, cultural, and sociological reasons of differential food access with long-term health outcomes that have multi-generational consequences.
