I. Introduction
The purpose of this literature review is to substantiate why planning is needed to address
the integration of edible landscapes into public parks and also to gain insight into the most
effective methods of analyzing food access and production potential in urban areas. Due to a
lack of literature specifically addressing “edible landscaping” in public parks, the scope of
literature evaluated for this report includes research on related topics such as food systems,
food access, and urban agriculture. In particular, articles or studies which detail planning
implications or methods for analyzing urban food systems and urban agriculture were included.
Appendix A details all of the keywords used in searching for related articles. In Appendix B,
findings are synthesized under four main themes which arose from the literature: proximity vs.
capacity for food production in urban areas, policy and planning effects on the food system,
assessing food access and distribution, and roles and responsibilities of local agencies,
community members, and educators.
Findings derived from the literature review will be utilized in the final report. Evidence from
the first two categories, proximity vs. capacity for food production in urban areas and policy and
planning effects on the food system, detail the benefits and problems with creating and
managing edible landscapes. These findings will be included in the introductory section of the
final report, which will introduce readers to the topics of urban food systems and edible
landscaping. Findings collected under the category, assessing food access and distribution, will
be synthesized in order to substantiate the data collection procedures and GIS analysis of this
research project. These findings will be included in the community profile and site assessment

of the final report. Finally, the category, roles and responsibilities of local agencies, community
members, and educators, will serve as a guide for collaboratively managing edible landscaping
projects in public parks. These findings will be included in the recommendations section of the
final report.
II. Main Themes and Debates
1. Proximity vs. capacity for food production in urban areas
A major theme in the literature was access to suitable land for urban food production.
While a number of studies would lead readers to believe that rural areas are the only viable
places for food production, multiple studies also provide evidence which suggests that urban
areas play a significant role in supporting the food needs of urban residents.
Five studies substantiated the idea that rural areas are better suited for food production
than urban areas. Ellis and Sumberg’s 1998 study in Tanzania found that proximity to urban
areas offers a cost savings advantage in the production of perishable foods (e.g. vegetables,
eggs, and milk).1 However, the study concluded by saying that, agricultural production requires
large amounts of land and is better suited to the urban periphery or rural areas where land is
cheaper.2 Ellis and Sumberg’s findings are supported through the 2011 study conducted by
Broadway and Broadway in Vancouver, which surveyed retailers offering local foods, finding
that the biggest impediment to urban agriculture is the growing population and rising property

values.3 The study uses the example of the Omni Community Garden, which lasted for two
years before being developed for housing, as a clear example of the lack of viable space for
urban food production in the face of residential development.4 Furthermore, Schmidt’s 2012
investigation into urban agriculture in Tanzania found that urban cultivators, utilizing open
space or privately held land, are frequently displaced due to the lack of ownership.5 The case
study found that from 1992-‐2005 the percentage of agricultural land did not change much.
However, the spatial distribution of urban agriculture changed as land became developed and
new areas became cultivated.6 While the study by Ellis and Sumberg was a meta-‐analysis and
arrived at its conclusions based on the premise that cheap and abundant land is more viable
than expensive proximal land, both the Broadway and Broadway study and Schmidt’s study are
case studies that provide concrete evidence as to why the displacement of centralized
agricultural land makes it difficult for agriculture to survive in urban areas.
In the same vein, Asomani’s 2002 survey of urban cultivators in Accra, Ghana, confirms the
difficulty in accessing urban land, finding that gaining access to suitable land was the most
common problem brought up by urban cultivators.7 Asomani’s investigation directly references
land use planning as one of the primary reasons in the City of Accra’s failure to facilitate urban
agriculture.8 Interestingly, Jarosz’s 2008 investigation into agriculture in and around Seattle,

Washington, found that while farms continue to move further from city boundaries, the
demand for farmer’s markets increases.9 Jarosz’s interviews with organic farmers also noted
their concern over the loss of manures from dairy farms leaving the region, exemplifying the
ripple effect of agricultural displacement.10 Both Asomani and Jarosz provide direct evidence
from people actively involved in food production, confirming that access to land for urban
agriculture continues to be a problem which drives farmers out of urban areas.
Although ample evidence supports the fact that rural areas offer access to more abundant,
cheap land, various studies highlight the potential for the expansion and innovation of urban
food production. Koont’s 2009 investigation into Havana, Cuba’s system of urban agriculture
provides evidence of such success. In Havana, production increases over time were attributed
to increases in cultivated land along with advances in technology and organization in cultivation
practices.11 Furthermore, the study found that urban food production minimized transportation
costs as well as the need for machinery.12 These advances were the result of a major effort by
the government to create a localized and sustainable food system, resulting in a complete
transformation of the country’s food system. Similarly, Hagey’s 2012 case study of Oakland,
California looked at the transformative food revolution currently happening there. The case
study found that one urban farming operation, City Slickers Farms, cultivates 21,569 sq ft of
land on seven farm sites in the city, producing 9,600 lbs of food in 2010, while additionally

aiding West Oakland residents in backyard gardening to produce about 24,000 lbs of food.13
Although this is not enough food to meet the needs of an entire city the size of Oakland, it is a
considerable amount nonetheless and demonstrates the potential that urban agriculture has in
supporting the food needs of urban residents.
Another example of the food production potential that urban areas offer is evidenced by
Grewal and Grewal’s 2012 study which found that fifty acres of community gardens in
Cleveland, Ohio, generate approximately $1.2 -‐$1.8 million worth of produce annually.14 The
analysis also estimated that the city has the potential to meet 100 percent of fresh produce
needs.15 While Hagey’s analysis is based on actual volumes of production, Grewal and Grewal’s
assessment is an estimation of potential food production projected from data gathered from
the city’s community gardens. Grewal and Grewal’s assessment is idealistic in scope because it
requires the city’s entire stock of vacant land and rooftops to use hydroponic systems, which
are soilless systems that recirculate water and nutrients. These findings, in conjunction with
those that suggest the preference for rural agriculture, help to paint a more holistic picture of
the food system. Urban and rural food production can coexist and the former is not likely to
replace the latter. However, they can operate as complementary models of food production.
2. Policy and planning effects on the food system
Policy and planning have been identified as playing a significant role in shaping the food
system, whether through facilitating or restricting food production and food retailing. Three

studies directly referenced that local agencies restricted food access and production at the
policy level. Black et al.’s 2011 investigation in British Columbia revealed that restrictive zoning
was a key variable in the distribution of food retailers.16 Likewise, Rogerson’s 2011 study of
Gauteng, South Africa and Schmidt’s 2012 study in Tanzania both found that policy restricted
agricultural cultivation in urban areas.17 Although the three studies varied in their objectives,
combined together their findings illustrate that local agencies play a vital role in planning for
and creating policy which facilitates access to food and food production in urban areas.
Similarly, Hubbard and Onumah’s 2001 international meta-‐analysis found that one of the
primary contributors to the inefficiencies in urban food supply and demand was that
developing cities are growing rapidly and city policy has not been able to adequately address
urban food supply and distribution problems.18 The investigation further noted that gaining
legal access to farming urban land is considered a burden,19 and concluded by saying that local
authorities need to lead improvements in urban food supply and distribution.20 The significance
of policy and planning is further echoed by Ellis and Sumberg’s 1998 study in Tanzania which
claims that urban agricultural policy should legitimize subsistence farming and gardening for

the urban poor,21 also suggesting that comprehensive policy is needed in order to address how
urban cultivators use and access land, including their cultivation operations and management
of agricultural inputs and outputs.22
Structuring and implementing urban food policies is often easier said than done. Martin
and Marsden’s 1999 study in England and Wales, which surveyed local agencies, found that
24.1 percent of respondents considered establishing urban food production initiatives;
however, the majority of respondents did not have a strategy for developing urban food
production.23 The survey also revealed that local authorities cited urban food production as a
method for combating poverty, amongst other benefits.24 However, Webb’s 2011 meta-‐analysis
of urban agriculture in Sub-‐Saharan Africa criticizes the economic benefits of urban agriculture
and cautions against the promotion of urban agriculture as a path out of poverty.25 Regardless
of whether urban food production can solve the problem of poverty there is clear evidence
which suggests local agencies are in a prime position to facilitate urban food production, with
the potential to supplement the food needs of any and all urban residents. Pothukuchi and
Kaufman’s 1999 meta-‐analysis of the involvement of local agencies in food systems planning
found that “local government agencies have responsibilities for such programs as nutrition
education, food stamps, WIC, food health and safety regulation, and school breakfast and lunch
21 Frank Ellis and James Sumberg, “Food Production, Urban Areas and Policy Responses,” World Development

9 | C a r v a l h o F i n a l L i t e r a t u r e R e v i e w
programs.”26 However, Pothukuchi and Kaufman’s 2000 survey of twenty-‐two planning
agencies in the U.S. found that their involvement was primarily related to locations of food
retailers and design of food outlets, and to a far lesser extent in community gardens, food
sector/economic impact studies, farmer’s markets, food-‐related comprehensive neighborhood
plans and economic development, hunger prevention, and agricultural land preservation. 27
Together, Pothukuchi and Kaufman’s studies demonstrate that there is a clear disconnect
between the potential that local agencies have in facilitating urban food access and production
and reinforcing the social welfare programs they operate. Planning agencies appear to have
prioritized their involvement with food retailers over food producers.
While policy and planning can often be restrictive, it is also foundational in facilitating food
access and production. Broadway’s 2009 meta-‐analysis of urban agriculture in North American
cities traced the origins of community gardens back to 1893, when the City of Detroit, with high
unemployment, began converting vacant lots to gardens, noting that community gardens
evolve as a response to economic depression.28 Broadway also points out the example of
California, which in 1995 adopted the policy for a “Garden in Every School”, which has been
credited with creating 3,000 school gardens by 2009.29 In the Broadway and Broadway 2011
Vancouver survey, it was found that the City Council made an effort to actively improve urban
food access and production by increasing community garden plots, easing restrictions on

biodiversity and farmer’s markets, and adopting an edible landscaping policy.30 Hagey’s 2012
case study of Oakland’s burgeoning urban agriculture system was partly the result of the city
taking the initiative to facilitate urban food production by setting clear objectives. In 2006,
Oakland set a goal of accessing 30 percent of food from the local region, also initiating a food
systems assessment and food policy council.31 Without well-‐defined goals and sound policies to
facilitate urban food production, many communities will struggle to meet the food needs of
urban residents without relying heavily on the private sector for imported food.
3. Assessing/measuring food access and distribution
All but one of the studies which focused on food accessibility and distribution used GIS
analysis; most of the studies utilized GIS in conjunction with some form of survey in order to
further substantiate their findings. The variables used in the assessments were not consistent
across studies, with most acknowledging the need for further investigation. Eckert and Shetty’s
2011 study in Toledo, Ohio, highlights an important overarching theme in assessing food access,
finding that access to food is two-‐fold: access to any food and access to healthful food.32 The
study also cites the lack of a standard measurement for accessing food, which makes it difficult
to make comparisons across studies or regions.33 For example, most studies focus on
supermarkets as the primary unit of measurement while Eckertt and Shetty found that small or

11 | C a r v a l h o F i n a l L i t e r a t u r e R e v i e w
locally owned food retailers fill in the gaps where larger chain retailers are not available.34 The
significance of convenience stores and smaller food retailers in providing access to food seems
to be supported by Hubley’s 2011 study and also Gordon et al.’s 2011 study. Hubley’s analysis
focused on Somerset County, Maine, finding that convenience stores in rural areas function
similarly to grocery stores, but in urban areas they did not.35 Gordon et al.’s analysis showed
that bodegas offering “healthy” food played a role in offering neighborhoods greater access to
healthy foods.36 Depending on the type of region being evaluated, the analysis needs to take
into consideration the way that retailers operate in the community before excluding them from
the analysis altogether.
The complicated nature of this problem is further evidenced by Burns and Inglis’ 2007 study
in Melbourne, Australia, which found that while areas with greater socio-‐economic advantages
had greater access to supermarkets than less socio-‐economic advantaged areas which were
closer to fast food outlets, over 50 percent of fast food chains were located next to or inside
grocery stores.37 Clearly, the use of supermarkets in measuring access to food, particularly
“healthy” food, is problematic. The Burns and Inglis study recognizes that there is a need to
better understand the relationship between food buying habits and food access.38 This
sentiment is echoed in Widener et al.’s 2012 study in Buffalo, New York where it was noted that
there is a need for a more complete approach in order to understand the consumer driven

12 | C a r v a l h o F i n a l L i t e r a t u r e R e v i e w
market forces behind food purchasing behaviors.39 The research in Buffalo demonstrated that
mobile produce vendors are capable of increasing access to healthy foods in food deserts.40
While both the Burns and Inglis study and the Widener et al. study found that shopping
behaviors play a role in food access, they arrived at this conclusion through very different types
of analysis, which would suggest shopping behavior is valuable evidence in assessing and
understanding food access. Simply stated, food access is less about proximity and more about
the food choices that are available.
Demographic variables like income and poverty rates, educational attainment, and racial
composition were commonly used when assessing food access at various levels of geography.
McEntee and Ageyman’s 2010 study found that in the State of Vermont, twelve census tracts
(4.5 percent of the state’s total population) are food deserts, with the nearest supermarkets at
least ten miles away.41 Possession of high school diplomas or higher education achievement in
those census tracts (81 percent) were slightly less than the state (86 percent); average poverty
rates were noted as higher (10.2 percent) versus the state’s average (9.8 percent); however,
the study noted that areas with the highest poverty rates and lowest educational achievement
were in urban areas.42 Based on these findings the correlations between food deserts and
poverty rates are weak, while the relationship between food deserts and lower educational
achievement is slightly stronger. Gordon et al.’s 2011 investigation into food access in New York
39 Michael J. Widener, Sara S. Metcalf, and Yaneer Bar-‐Yam, “Developing a Mobile Produce Distribution

City utilized GIS analysis in conjunction with a food store index that rated the availability of
healthy foods at various food retailers. The study found that in Harlem and Brooklyn, food
deserts corresponded to areas with the highest proportions of Black populations and also the
lowest median household incomes, while neighborhoods with the highest proportions of
Latinos had greater access to healthy foods.43 Black et al.’s 2011 study in British Columbia
acknowledges that there are contradictory findings amongst other studies, ultimately
questioning the correlations between food deserts and income level or minority status.44 In
fact, Black et al.’s study, which looked at residential proximity to food stores, found that small
food retailers were more frequent than large supermarkets and areas with higher income levels
had less access to all types of food retailers.45 These findings conflict with the findings from
both McEntee and Agyeman’s study as well as Gordon et al.’s study. Furthermore, Black et al.’s
study found that small food retailers correlated with availability of ethnic foods.46
If racial composition of a community plays a factor in food access, there is clear evidence
that smaller food retailers play a significant role in the availability of ethnic foods. It should also
be noted that McEntee and Agyeman’s study analyzed the entire State of Vermont by
measuring stores within ten miles of residences and the study also excluded convenience stores
from the analysis. Gordon et al.’s study recognized the value of small retailers by including

14 | C a r v a l h o F i n a l L i t e r a t u r e R e v i e w
bodegas in the assessment. It was not clear whether each study categorized small or
independent food retailers along with convenience stores. Again, this draws attention to the
need for a more consistent standard of measurement in assessing food deserts and food
access.
Interestingly, none of the studies took into consideration proximity to farms or community
gardens for measuring access to food. Kremer and DeLiberty’s 2011 study in Philadelphia,
Pennsylvania, found that over 50 percent of the local community gardens were located in low-‐
income neighborhoods (median income of $18,000 or less annually).47 Similarly, Corrigan’s
2011 study, the only analysis that did not use GIS as a tool for assessment, found that the
Duncan Street Miracle Garden in Baltimore is located in a region with few “quality” food
options, mostly corner stores, liquor stores, and bars or restaurants.48 Corrigan surveyed urban
cultivators, finding that most gardeners rarely buy produce from local stores because they grow
their own and donate any surplus.49 If community gardens allow residents greater access to
food small markets and convenience stores may be useful in providing other food needs. The
issue of food access is further compounded when taking into consideration the way urban
gardeners contribute to urban food production.
4. Roles and responsibilities of local agencies, community members, and educators
With respect to roles and responsibilities for urban food production, the overall finding
throughout the literature was that everyone has some degree of responsibility in sustaining and

supporting the urban food system. Six different studies suggest that urban food production is
highly dependent on collaboration between several key players: local government agencies,
non-‐government organizations (NGOs), educators, and community members. Feenstra’s 2012
analysis of California grant recipients of the Sustainable Agriculture Research and Education
Program (SAREP) notes three main themes: public participation, partnerships, and principles or
values, further noting that projects take two to three years to develop, on average.50
Pothukuchi and Kaufman’s 1999 study points to potential partners in improving urban food
systems as the department of food (non-‐existent in the U.S.), food policy councils, and city
planning agencies.51 Similarly, Rogerson’s 2011 examination in South Africa found that urban
agriculture initiatives are the result of joint efforts of multiple stakeholders (provincial
government, NGOs, and local municipalities).52 Further supporting the need for collaboration,
Spencer’s 2011 case study of the Philadelphia Orchard Project found that one of the key
components in the program’s success was their partnerships with organizations with legal
access to land and water.53 Mendes et al.’s 2008 case study of two collaborations between local
governments and universities in Portland, Oregon, and Vancouver, Canada, highlighted the role
education can play in practical planning problems. The Portland City Council approached the
Department of Urban and Regional Planning at Portland State University to perform a land

inventory to assess land for community gardens and other forms of urban agriculture.54 An
assessment following the lead of the study performed by students in Portland was conducted in
the City of Vancouver and the Mendes et al.’s study found that both land inventories enabled
integration of urban agriculture into planning and policy making.55 Local governments are well
positioned to collaborate with universities, NGOs, and community members alike.
Westphal’s 2001 case study of the agricultural preservation effort on the Old Mission
Peninsula in Michigan exemplifies the key role community members play in protecting
agricultural resources. Originating from the bankruptcy of a 500-‐acre farm, residents came
together to form an oversight committee to protect the agricultural land from development.56
In order to preserve the agricultural zone, community members recognized the need for the
community to pay for the preservation of the land. It was decided that the community would
enact a 1.25 millage increase on property taxes in order to provide money to facilitate the
purchase of development rights. The tax increase was made possible by a voter referendum;
however, state law prohibited local government from taking part in issues relating to
referendum, requiring the formation of an oversight committee to facilitate the funding for the
purchase of development rights.57 All six studies were either case studies or meta-‐analyses with
the exception of Feenstra’s study which included a survey of SAREP recipients. All of the studies
exemplify the importance of collaboration between government agencies, NGOs, educators,

Local agencies play a significant role in facilitating urban food production. Martin and
Marsden’s 1999 study in England and Wales found that local authorities owned suitable vacant
land.58 Martin and Marsden further noted that, “urban food production promotes local
distinctiveness, encourages community development and self-‐sufficiency.”59 Thornton et al.’s
2010 survey of urban agriculturalists in Zambia found that the majority of respondents in four
different cities expressed the need for help from the government in farming, marketing,
training, disease control, and extension support.60 The study cites that lack of policy support,
funding, and land were identified as the main obstacles for urban cultivators, indicating that the
government should play a role in facilitating urban agriculture.61
Examining agriculture in Somerset, England, Nichol’s 2003 study found that food producers
are experiencing pressure to expand their operations into food processing and retailing.62 The
review of planning documents revealed 309 instances where local producers contacted
planning authorities (253 were planning applications, 69 percent were for new buildings,
facilities or extensions).63 Upon surveying the food producers, “half of producers reported that
the planning system had been a problem for their business.”64 Local government agencies,
particularly planning, are clearly in the position to promote and facilitate urban food

production, food producers have expressed that there is room for improvement in regards to
the way local agencies regulate food production and retailing.
While local agencies hold significant power in the development and preservation of urban
food production, NGOs are also responsible for the success of urban agriculture projects. Two
studies showed evidence of NGOs that were created through active community members and
cultivators. Metcalf’s 2011 case study of Buffalo, New York, mentions how in 2008, several
urban farms came together to create a Community Garden Task Force, later known as the
Buffalo Growing Coalition, which serves as a network and resource group for local food
producers.65 Broadway’s 2011 case study of Vancouver, Canada, showed how a local non-‐profit,
City Farmer, ultimately came to serve as the office of urban agriculture, a resource and
educational center.66 Both studies illustrate how non-‐government organizations are useful in
assisting urban food producers.
Along the same line, Hamm’s 2003 meta-‐analysis of community food security programs in
the U.S. emphasizes the importance of nutritional educators as individuals who are trained to
identify problems and offer solutions, possessing specialized skills in research and analysis, and
also having the ability to critique and influence social welfare policies.67 The need for nutrition
educators in supporting urban food production is supported by Hu et al.’s 2013 neighborhood
assessment of an unidentified mid-‐Atlantic city which utilized interviews and focus groups with

community members to gather findings. Community members identified the need for
education around nutritious food preparation along with the need for easily accessible,
consistent farmers markets.68 While the availability of locally produced foods is important to
urban residents, food preparation and preservation need to be addressed in order to help
community members make the most of the locally produced foods. Another benefit is
exemplified in Travaline’s 2010 study in Philadelphia, Pennsylvania, which interviewed
participants in urban agriculture organizations, finding that social learning benefits included a
greater awareness of food origins as well as learning how to be effective citizens through group
participation.69 Community members are at the heart of urban food production. Without a
population to support local food producers, it would not be feasible for them to maintain their
operations in the urban environment.
III. Conclusion
Proximity to urban populations and capacity of urban land are major factors in many of the
problems related to the urban food system and the resulting effects on food access and
distribution. In most places, policy and planning have produced mixed results in facilitating
urban agriculture. The research identifies land inventories as important tools in locating space
for urban agriculture; however, site suitability is not something that has been fully addressed.

It is also apparent that there is a lack of consensus regarding the variables for assessing
access to food. Demographic variables used in analyzing communities did not produce
consistent results across studies but revealed a need for a better way to assess food access.
Some studies indicated the need for a greater emphasis on evaluating food choices, particularly
in regards to “healthy” food. In terms of roles and responsibilities, it is apparent that key
players at all levels play significant roles in the successful implementation and viability of urban
food systems, but community members are perhaps the most vital in the future and
sustainability of urban food production.
The majority of literature reviewed in this research focuses on urban agriculture projects,
which are led by non-‐profits, NGOs, or as private enterprises. However, edible landscaping in
public parks is more likely to be a collaborative effort between local government agencies,
NGOs, and community members. The analysis of how to integrate edible landscaping in public
parks will provide insight into methods for implementing and managing edible landscapes. GIS
analysis examining park proximity to schools, community centers, libraries, and public
transportation systems, in conjunction with a site assessment to evaluate growing conditions,
will provide a method for assessing the viability of edible landscaping in public parks.
