Abstract:Urban agriculture is touted as a strategy for more locally reliant food systems, yet there is little understanding of its potential food provisioning capacity. Using Detroit, Michigan as an example, we use secondary data to develop a methodology for estimating the acreage required to supply, as far as seasonally possible, the quantity of fresh fruits and vegetables consumed by city residents. We compare these requirements with a catalog of the publicly owned, vacant parcels in Detroit to assess the feasibility… Show more
“…Cool, wet winters and warm, dry summers allow for over 170 different crops to be grown in this fertile region (ODA, 2009b). Steady rainfall occurs from December through February, followed by relatively aridity in summers, which average only five percent of the total annual average precipitation (PNW-ERC, 2002 (Coba, 2010). Despite these numbers representing Oregon as a whole (rather than the Willamette Valley growing region alone) and the …”
Western Oregon's Willamette Valley has a rich history of agricultural production and, like an increasing number of regions globally, a growing local food movement. Recent declines in grass seed markets and an increased consumer interest in local grains have raised the possibility of a transition from grass seed land to edible grain production for local markets. We used geographic information systems (GIS) to determine if the Willamette Valley population's dietary grain needs could be met if current grass seed land were converted to production of soft white winter wheat. In order to explore transitional obstacles and opportunities, we conducted interviews with local farmers, a wholesaler, an agriculture extension worker, and seed developers. The GIS analysis indicated that such a transition could exceed the recommended grain needs of the region's 2008 population. The interviews revealed technical and cultural aspects of transitioning from grass seed production to wheat and other edible crops, identifying insufficient infrastructure (storage, processing, distribution, and market outlets) as the primary barrier to producing for local markets. This combination of GIS analysis (predictive of the food-producing capacity of a region) with in-depth contextual information and practical insights from farmers' voices provides a robust model for planners seeking to analyze and address local food system challenges and possibilities. Our research, while focusing on the Willamette Valley's transition toward a more locally based food system, explores the potential steps for any region looking to transition from nonedible to edible crop production for local consumption.

“…Applying a distribution lens to the existing literature yields similar results to the food access analysis in that several articles theorize idealized distribution systems, showing the capacity of hypothetical urban and peri-urban farms to supply distribution networks that meet most urban food demands [40,[53][54][55][56][57]. Others highlight barriers and challenges farmers face in practice around distributing their produce to those in need while maintaining their operations [72,73].…”

“…Other theoretical mapping analyses have also found that urban and peri-urban farms can supply significant amounts of food demand in urban centers: from 5-10% of city vegetable demand supplied by expanded UA on public lands in Oakland [18] to 30% of seasonal vegetable demand in Detroit [57], to 100% of nutritional needs in Southeastern Minnesota [54]. However, very few studies directly quantify how much urban produced food is actually being consumed by low-income food insecure communities, requiring observational and qualitative research methods.…”

Abstract: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.
“…Vacant Lot Cultivation Associations facilitate gardening on vacant land and encourage the poor to grow food for sale and self-consumption [26] and land trust lease and acquisition programs enable communities to maintain gardens [11]. In underserved neighborhoods, Cooperative Extension support for food production [26] operate side-lot or "abutter" programs that encourage residents to manage the land between buildings, as well as a more recent integration of community garden and urban agriculture programs that is contributing to the creation of more sustainable planning processes [27][28][29].…”
This study reviews scholarly papers and case studies on urban vacant land to gain a stronger understanding of its public value in terms of the ecological and social benefits it can bring. This literature review offers a conceptual overview of the potential benefits of vacant land with the goal of addressing gaps in knowledge about vacant land and to provide suggestions to planners and designers on how vacant properties can be integrated with other green infrastructure in cities. There are many opportunities to redevelop vacant land to enhance its ecological and social value, and many design professionals and scholars are becoming interested in finding new ways to exploit this potential, especially with regard to planning and design. A better appreciation of the public value of urban vacant land is vital for any effort to identify alternative strategies to optimize the way these spaces are utilized for both short-term and long-term uses to support urban regeneration and renewal. This study will help planners and designers to understand and plan for urban vacant land, leading to better utilization of these spaces and opening up alternative creative approaches to envisioning space and landscape design in our urban environments.
