1.0 Introduction
Food and shelter are two basic necessities for every person. These essentials
are in acute shortage both regionally and globally, due to the exponential growth of
population and migration towards cities. In the City of Toronto, nearly 1 million people
are food bank users as of 2010 (DBFB, 2010). Government-assisted housing has been
in short supply for fourteen consecutive years since 1997 (City of Toronto, 2004). The
city has struggled to resolve these two critical issues throughout the past decade. This
study focuses on incorporating urban agriculture with affordable housing as a building
typology in order to create architectural models that not only provide shelter, but allot
space for low-income households to grow their own food. It is expected that by making
these elemental needs available, accessible, and affordable, the problem of food
security will be met, the food system will improve, and the housing shortage within the
City of Toronto will be eased.

1.1 Background
As of 2008, the Greater Toronto Area (GTA) has been home to over 6 million
people. The province of Ontario alone is projected to receive 125,000 foreign
immigrants each year, which makes up more than half of Canada’s total annual
immigration (Statistic Canada 2006). The census trend shows that over 50 percent of
new Ontario immigrants decide to live in Toronto (Statistic Canada 2006). According to
the Ontario Ministry of Public Infrastructure Renewal Schedule (Lister 2007), the GTA’s
projected population by 2031 will reach close to 8.6 million. This makes the GTA one
of the fastest growing metropolitan cities in North America. Furthermore, from 2001
to 2006, 46 percent of new immigrants were considered as low income (Finance &
Administration 2006).
Shelter, food, and transportation are the main expenses for a Canadian family (see
Figure 1.1). The lowest-income Canadian household with an average income of
$17,064 spends an average of over 32 percent of their total income on shelter, over
18 percent of their income on food, and about 13 percent on transportation. The
percentage of income saved by the wealthy class is a positive 13.1 percent and 3.1
percent for the average income class in Canada; for the low-income group, it is a
negative 30.9 percent. For the latter group, after expenses are deducted from earnings,
there is little or no money left to be saved, which makes this group vulnerable to crisis
and at higher risk of poverty. Over the years, urban poverty in Toronto has increased
to such an extent that about 1 in 5 people live in poverty. About 552,300 households
have incomes under the poverty line (Toronto Real Estate Board 2003) and many of
these are new immigrants. In 2004, 95,750 Toronto households spent more than 50
percent of their income on rent (City of Toronto 2004). Consequently, a new affordable
housing typology must be developed which not only provides accommodation, but also
generates opportunities for employment and self-sufficiency in food production. It would
help the city overcome its housing shortage, scale up urban agriculture, offset food
expenses for the low-income population, and provide opportunities for these groups to
improve their quality of life.

The following is a brief definition of some terms that will be used in this paper.
A food system is defined as a complex set of activities and relationships related to
every aspect of the food cycle, including production, processing, distribution, retail,
preparation, consumption and disposal (TPH 2010). A food shed is defined as the place
that collects the food products grown in local farms surrounding a given urban area, and
routes them into the city to be made available to the population that will consume them
(Lister 2007).
The current food system in Toronto is ridden with many issues which make
it unsustainable, especially in relation to food import and accessibility problems.
Production occurs in the GTA, mainly around the peripheral cities within a 200-kilometer
radius. However, there is no significant scale of crop production within the City of
Toronto. This illustrates the city’s reliance on imported food, and it follows that food
availability, accessibility and adequacy are not under control. Adequate food and health
are directly related (see Fig 1.2.1).

food deficit = $3.0 billion
food miles average = 4,500 km
food bank users = 997,000
Overall food bank access has steadily increased each year in Toronto (see
Figure 1.2.3). In 2010, the count went up to 997,000 users (DBFB 2010, p. 12).
Community food programs serve almost 20,000 meals per day in order to cater to
those in need (DBFB 2007). Among food bank users, 54 percent of individuals do not
eat for a whole day in a week due to the lack of money. The duration of their reliance
on food banks is an average of 18 months (DBFB 2010, p. 5). Amongst regular food
bank users, 34 percent are children and youth under the age of eighteen (DBFB 2010,
p. 4). However, more than 1 in 3 Toronto children are overweight or obese (TPH 2004)
and many are from poor families and suffer from drastic imbalances in nutrition. In
Toronto, 1 in 14 residents over the age of 40 is affected by a heart-related disease,
and 1 in 15 has diabetes (TPH 2005). This indicates that poverty and poor health are
interconnected. Inadequate nutrition is related to a predisposition to obesity among the
poor (Laurie, 2008). Thus poverty leads to both malnourishment and obesity and access
to healthy food is an essential part of any solution.

The difficulty with providing food access is further demonstrated in the food
desert map of Toronto. Food deserts are defined as large areas in the city where it is
difficult or impossible to find a grocery store or supermarket within walking distance,
thus making fast-food outlets and higher-priced convenience stores the most frequented
places for food purchases (Lister 2007). This means there is unsatisfactory food
distribution in some neighborhoods in Toronto. On the other hand, many downtown
areas have food available within walking distance, though it may not necessarily be
affordable for the local residents. Hence, low-income groups, especially near the city
center, still suffer as a consequence of high food prices.

According to the notes of the Mayor’s Affordable Housing Summit in 2004,
Toronto has endured a consistent 14-year shortfall of government-assisted housing
production since 1997 (City of Toronto 2004). The government has failed to satisfy the
demand for affordable housing, and this gap has been widening every year. Between
1997 and 2010, this shortfall of government-assisted housing has accumulated to
24,561 units (see Figure 1.3). There were 76,549 households on the social housing
wait list in 2010; this was an increase of 5,051 more households than the previous
year (City of Toronto 2010). These are modest estimates; in reality there could be more
Torontonian families who are at risk of facing the realities of poverty and homelessness.

1.4 Research Questions
The second premise raises questions regarding qualitative factors that will
reinforce the quantifiable data on spaces for growing, eating and living, in terms of
program, system, and technology implementations:
a. What are the possible programs to enrich the integration and relationship
between farming and living space?
b. What are the possible technologies that can be integrated?
c. How can we grow a variety of crops and provide safe food with multiple
14
nutrients to users?
d. How can we make a closed-loop system in the building community and the city
for self-sustainability?
e. How can a strategy be developed in order to secure the viable combination
of urban agriculture and affordable housing, covering both short-term and long-term
prospects?
1.5 Methodology
The report is structured into three parts consisting of nine chapters. The first part
provides background information, summarizes basic knowledge and theories past and
present, and puts forth a proposal for urban agriculture. The second part explores a
set of design considerations and parameters, and synthesizes a strategy to define the
typical design requirements for food production spaces and low-income housing. The
third part focuses on site investigation, consolidates the findings and parameters into a
design proposal, and concludes the research with a design intervention.
This research will develop a conceptual framework (see Figure 1.5) to integrate
knowledge and principles of agriculture and architecture in an urbanized district of a
city; this frames the design intention of maximizing agricultural productivity along with
affordable accommodation in an urban setting, thus making food and shelter available,
accessible, and affordable for low-income groups. This thesis demonstrates a model
that could help cities alleviate concerns of urban poverty, improve food security and
increase the supply of housing wherein both agriculture and housing could co-exist.

1.6 Location
Toronto’s Chinatown neighborhood has been chosen as the study area for this
research investigation, based on its income statistics: this neighborhood has the lowest
median income and the highest average percentage of low-income families and single
adults below Low-Income Cut-Off Rate (LICO), as well as the highest percentage of
households within downtown Toronto that spend over 30 percent of income on rent. In
addition, 41 percent of homes in this neighbourhood require major and minor repairs,
one of the highest figures in this category (Statistic Canada 2006).
Chinatown is the poorest district near the urban core of Toronto. Implementation
of urban agriculture and new affordable housing development in the neighborhood will
provide safe food access and shelter for the individual low-income household. Further,
the growing and harvesting process promotes farming education, social engagement,
and cultural exchange within the community. At a macro level, the model scales up
local food production, supplying local food market and restaurants with fresh food and
reducing their dependence on imported food. The design is also intended to be a closed
loop system, recycling waste and water, minimizing the environmental impact, and
enabling the district to sustain itself.

After gaining an understanding of the food and housing issues in the current urban
conditions, Chapter 2 addresses the essential elements that will determine design
objectives. This chapter is structured into two sections. Sections 2.1 and 2.2 define
the term urban agriculture and explain its benefits. Sections 2.3 and 2.4 elaborate on
the elements that need to be considered for food security. This chapter is intended to
develop a conceptual framework by addressing the basic criteria of the design project,
in order to identify the future role and potential of urban agriculture in architecture.
18
2.1. Definition of Urban Agriculture
The idea of urban agriculture has been previously explored. The concept of
growing food in urban areas has been reintroduced in the years after WW2. Many
urban thinkers have begun to wonder how to continue feeding the population that
throngs cities. Perhaps the answer is literally embedded within the cities, in the form
of a new system of urban agriculture. There is no rigid definition of urban agriculture;
it could mean something as simple as the growing of plants and the raising of animals
for food and other uses within and around cities and towns (Veenhuizen 2006). Urban
agriculture is defined as an industry that produces, processes, and markets food and
fuel within a town, city or metropolis on land and water dispersed throughout the urban
and peri-urban area (Cheema, Smit, Ratta, & Nasr, 1996). Urban agriculture as a
system is concerned with urban culture, use of natural resources, land-use planning,
food production and security, education and leisure, social relationships and income
generation (TFPC 1999, p/ 6).
These processes may take place in locations that are within intra-urban and
peri-urban zones within a rural-urban-transect (see Figure 2.1.). A transect is defined as
a geographical cross-section, which has distinct characteristics of a region and reveals
a sequence of environments. Urban agriculture can be viewed as a continuum with
landscape stretches from backyard and community gardens to small, medium or large-
scale commercial farming facilities (TFPC 1999, p. 6). In short, there is no restriction
of place nor limitation in size for urban agriculture, allowing it to be accommodated
anywhere within a city or town.
The majority of players involved in urban agriculture are the urban poor. These
groups include immigrants, HIV-AIDS affected households, disabled people, single,
divorced or widowed women with children, elderly people without pensions and
unemployed youngsters. The integration of these groups into an urban agricultural
network helps to provide decent livelihood and prevent social problems (Veenhuizen,
2006).
19
In both urban and peri-urban zones, agricultural land could take on a significant
role in providing educational and recreational functions and in rejuvenating natural
landscape biodiversity in a larger context (Veenhuizen, 2006). The three main streams
of urban farming are ecologically, socially or economically oriented (Veenhuizen, 2006).
Urban farming, in any of these orientations, not only facilitates food provision
and generating income, but also yields other advantages besides the basic functions
(see Figure 2.2). Ecologically oriented urban agriculture (Environmental Healthy City)
typically has a multi-functional character. The farm design encompasses features
like decentralized composting, reuse of organic wastes, wastewater treatment,
economic use of water and nutrients, pollutant reduction, shading, improvement of
urban climate, and provision of leisure and recreational activities (Vennhuizen 2006).
The social function of an urban agricultural model refers to a subsistence-oriented
approach (Inclusive City), which focuses on producing food and medicinal plants
for home consumption (Vennhuizen 2006). The households involved in this type of
farming usually need other sources of income to survive. Any surpluses of production
are sold to generate additional income for the family’s food and medical expenses
(Vennhuizen 2006). Although this model demonstrates only an indirect profitability to
the disadvantaged group, it does make a more positive social impact on their livelihood.
20
2.2. Benefits of Urban Agriculture
In the environmental context, urban agriculture can reduce the overall ecological
footprint of a city. By shortening the distances between the locations of production
and consumption, energy consumption and greenhouse gas (GHG) emissions can be
reduced. This subsequently lowers costs of storage and transportation of produce. By
using farms and organic soils as carbon sinks, the local microclimate is also improved.
Urban waste such as organic matter and wastewater can be recycled as compost and
biogas (TFPC, 1999).

(ENVIRONMENTAL HEALTHY CITY) (PRODUCTIVE CITY)
Food quantity, quality, stability, and nutritional balance (Cheema, Smit, Ratta, &
Nasr, 1996) are the four major determinants that have been classified as measuring
factors for the quality of urban agriculture. Furthermore, these measurements are
assessed by both quantitative and qualitative parameters in order to determine the
effectiveness of urban agriculture within a specific site. The term urban agriculture in
this research paper applies to food productivity, security, and distribution related to the
urban, community, and building scale. This research thesis provides both quantitative
and qualitative measuring factors for food quantity, quality, regularity, and nutritional
balance, to design a new typology that benefits low-income communities socially,
economically, and environmentally.
22
2.3. Food Security
According to the Food and Agriculture Organization of the United Nations (FAO),
Food Security “exists when all people, at all times, have physical, social, and economic
access to sufficient, safe, and nutritious food which meets their dietary needs and food
preferences for an active and healthy life.” (FAO 2006). Food insecurity “exists when
people do not have adequate physical, social or economic access to food as defined
above.” (FAO 2006).
In order to achieve food security for each person, there are three major criteria
that need to be met both qualitatively and quantitatively. The three criteria are quantity,
safety and quality. These three factors must be evaluated, based on the physical, social,
and economic aspects of food. The Centre for Studies in Food Security at Ryerson
University (RU, 2009) has subdivided the definition of food security further into five
interconnected yet distinguishable components. The five components that form the
framework of food security are availability, accessibility, adequacy, acceptability, and
agency (RU 2009). Each component is further defined to explore the several facets in
depth. The following discussion will address some factors that affect each component of
food security both quantitatively and qualitatively.
Food Availability
Food availability is defined as sufficient food for all people at all times (RU
2009); it also means sufficient quantities of food available on a consistent basis (FAO
2006). Availability refers to supply and consumption. An average estimated minimum
daily energy requirement for a human is 2,200 kcal / day (calories per day), according
to FAO. The calorific intakes are uneven in a global perspective (see Figure 2.3.1);
some countries suffer from malnourishment or over-consumption, leading to obesity.
Food consumption around the world ranges from below 1600 kcal / day to over 3600
kcal / day. Therefore, it is essential to quantify what is a sufficient amount of food to be
produced and consumed, in order to ensure that sufficient amounts of food are made
available equitably.
23
Other factors that affect the availability of food are directly related to the climate
and weather, resulting in the varying of the yield and harvests each year. Food types
and choices also differ according to the geographic location. Furthermore, inadequate
storage facilities in most circumstances lead to heavy product losses, significantly
affecting the seasonal availability of food.
Food Accessibility
Even if a city can ensure food availability and consumption, it cannot be assumed
that people have access to the food. Food accessibility is defined as having sufficient
resources to obtain appropriate foods for a nutritious diet (FAO 2006). Food accessibility
exists when physical and economic access to food for all at all times is ensured (RU
2009). Physical and economic accessibility of food refer to distance and price, and are
both quantifiable in numbers.
24
Food Adequacy
Even if people are able to access affordable food, it does not necessarily follow
that the food is adequate in quantity or contains all of the required nutrients (FAO 2006).
Food adequacy exists when people have access to food that is nutritious and safe,
and produced in environmentally sustainable ways (RU 2009). Individual citizens need
knowledge of basic nutrition and care, adequate water consumption and sanitation.
Inadequate, inopportune selling in an unfavorable market can have a detrimental effect
on food security (FAO 2006).
Food quality depends a great deal on the food distribution system. In the case
of an imported food item, the longer the item travels, the higher the risk of that item
losing its freshness and nutrients. For urban farming, it is important that households
use adequate water for irrigation and grow food organically. Thus, eliminating the use of
chemicals and pesticides could also ensure food adequacy.

Food Agency
Food agency, in brief, is defined as the policies and processes that enable the
achievement of food security (RU 2009). The City of Toronto introduced the Green Roof
policy by-law in May 2009, stipulating that all commercial, institutional and residential
developments with a minimum Gross Floor Area (GFA) of 2,000m2 must have green
coverage on the roof of the building. The requirement applies to 20 to 60 percent of
buildings that have more than 6 floor levels or 20m in height (City of Toronto 2009). This
legal stipulation opens up a huge potential for urban agriculture to expand, by making
the building roof a productive and edible landscape.

3.0. Urban Agriculture and Theories
The Phalanstere was proposed by Charles Fourier, a French utopian socialist and
philosopher. Fourier envisioned a model with a single building complex comprising all
types of agricultural and manufacturing work to build a utopian community (see Figure
2.3.1), that could be self-sufficient (England 2009). He believed in a collective social
order, where individuals create mutual benefits through shared effort. He described
diverse types of working facilities and environments for different groups of individuals in
30
Figure 3.1.1 - The Phalanstere Floor Plan
the Phalanstere. These activities included agriculture, manufacture and applied science
and arts (England 2009).
One lateral wing consists of units to accommodate labor and noisy activities, whereas
the other lateral wing is used for visitors, and has venues for social activities such as
ballrooms (England 2009). The middle of the plan is a grand square for large-scale
31
Figure 3.1.2 - The Phalanstere by Charles Fourier
events. The backyard section holds workshops, warehouses, sheds, barns and farming
facilities. The farming facilities are ideal for growing a variety of crops on hilly slopes
(see Figure 3.1.2).
The size of the Phalanstere is about 1920 acres (7.770, 000 m2) and houses
1620 individuals, with a density of 0.21 units per acre. The model includes all types
of agricultural products (England 2009). The vision of Phalanstere suggests designing
a community where different classes live in proximity and harmony. The organizing
principle is to distribute programs and functions according to the individual labourer’s
skills and aptitude. It creates opportunities for different classes and occupations to
interact and share efforts and ideas. In the plan, the housing units are laid out as a ring
that wraps around the area forming perimeter blocks with courtyards. This formation
reserves spaces for growing in both the exterior and interior sections of the complex.
32
Figure 3.1.3 - The Garden Cities Planning by Ebenezer Howard
The Garden City was proposed by Ebenezer Howard, a British urban planner
and philosopher. He envisioned that people in a utopian city should live in harmony with
nature. In his publication, Garden Cities of To-morrow, he deemed that the current ideals
of town and country themselves created social tragedy and argued for a human scale.
As a remedy, Howard proposed the concept of “Town-Country”, a combination of the
two ideals, which would create a balanced environment (England 2009).
His Three Magnet Diagram (see Figure 3.1.3), illustrates the advantages and
disadvantages of town and country. With the combination of town-country, new cities
could adopt the social advantages of cities while the design’s countryside atmosphere
eliminates their disadvantages (England 2009). This in turn would create slum-free,
smokeless cityscapes.
33
The Garden City addresses land ownership, population and functions as the
three key points of its vision. Firstly, land development should be held by common
authority and not parceled out for individual ownership. In other words, the Garden City
must be reserved for the community (England 2009). Secondly, growth and population
of the city must be controlled and limited. The city must contain areas that are
permanently reserved for open country, which is used for agriculture and recreation. The
agricultural belt not only serves as a green wall against encroachment of surrounding
communities, it also provides opportunity for local food production (England 2009).
Thirdly, the region’s political, social, and recreational functions should be in balance,
with the internal developments addressing home, industry and market areas (England
2009).
Broadacre City was a utopian vision for America proposed by Frank Lloyd Wright.
The Broadacre City model suggests a new community plan for America, by providing
each citizen with at least one tillable acre of land, a homestead for the household
and their own car for transportation. This model aims to develop a community where
members would be partially, if not wholly, responsible for their own-self-sufficiency
(England 2009). Standardized machines, radio, telephone, telegraph, and automobiles
were the inventions that built the old cities (Wright 1935). Wright foresaw that, in the
future, individuals would not be limited in range. The proposal is to view the whole
country as a continuous grid, and thus restore citizens to a fundamentally agrarian
landscape (England 2009). According to this model, each family would require one acre
within a confined boundary (see Figure 3.1.4).
Broadacre City has attempted to bring about social equality and interaction
between classes by empowering the citizens with three inherent social rights,
35
which were: the use of gold as a commodity for exchange; land held for use and
improvements; and the public ownership of inventions and scientific discoveries
concerning the life of the people (Wright 1935). The land could be developed with the
occupants’ freewill as the coordinating and organizing principle; the land could become
“little farms, little homes for industry, little factories, little schools, a little university going
to the people mostly by way of their interest in the ground, little laboratories on their
own ground for professional men” (Wright 1935), which allows the Broadacre to expand
and evolve organically and naturally. In this model, each household would be allotted
one acre of land for accommodation, while ensuring that the development does not
overshadow the biosphere. “Here architecture is landscape and landscape takes on the
character of architecture by way of the simple process of cultivation” (Wright 1935)
This section examines different cases in which agriculture and food have been
integrated as part of the design, making an impact socially, environmentally, and
economically at the community level. The aim for this section is to analyze and identify
the possibilities and potential ingredients of the final design response, such as programs
and systems that could be incorporated as well as their direct and indirect benefits to
the community.
Victory Gardens
During the world war periods, Victory Gardens largely contributed to the food
supply of different countries. During WW1 in 1917, Europe was facing food shortages
and Americans were asked to voluntarily reduce their consumption of exportable
foods through conservation, substations, buying from local growers, and gardening
(Lawson, 2005). By the end of 1918, there were 5,258,000 gardens planted. The name,
Victory Gardens, celebrated the success of the scheme in producing food, promoting
civic involvement and patriotism (Snowdon 2010). After the war, those lands were
repurposed to their former functions and eventually they became vacant (Lawson
2005). During WW2, the Americans re-launched the Victory Gardens campaign. (see
Figure 3.2.1) It is estimated that there were about 20 million Victory Gardens providing
approximately 40 percent of all vegetable production for the entire nation (Snowdon
2010).
In the City of Toronto, there were similar movements during the Great Depression
and World War periods. In 1934, Toronto Mayor William James Stewart turned an
8-hectre plot on St Clair Avenue into community gardens, providing land for 5,000
unemployed families to grow food. In 1918, the Toronto Vacant Lots Cultivation
Association had 2,000 gardens and managed to grow $75,000 ($980,000 in 2009
dollars) worth of food in profits (Palassio& Wilcox, p. 60).
37
Figure 3.2.1 Victory Garden Posters
Horticultural Club’s Victory Garden Committee cultivated 425 gardens in Toronto. The
land donated by municipal and private owners grew $26,000 ($331,000 in 2009 dollars)
worth of food. Major streets, such as Bayview Avenue, Queen Street, Keele Street
and Cosborne Ave, together cultivated food equivalent to $30,940 ($385,741 in 2009
dollars). During these periods, Canada had more than 200,000 wartime gardens, each
producing an average of 225 kilograms (Palassio & Wilcox 2009, pp. 58-59).

The total area of the complex is about 5600m2. This area contains public
green space, a greenhouse, farmer’s market, a beach-volleyball court and an office
for community groups and housing for artists. In addition, there is a compost area,
an industrial kitchen that can accommodate both indoor and outdoor events and
gatherings, as well as a sheltered court that houses fruit trees and sensitive large plants
(RU 2010).

3.3. Urban Agriculture in Building Scale
This section examines buildings that have incorporated agriculture and food
as key elements of their design. The intention is to investigate how spaces for food
and accommodation could be integrated to benefit the users of the buildings socially,
environmentally, and economically.
The community garden located on the sixth floor is one of the key features of
the building. The terrace space is a productive garden tended by the residents. A metal
framework placed on the east side of the central void is used as a vertical growing
42

wall for landscaping and contributes to natural ventilation by having climbing vines
cascading down the atrium space. These designs demonstrate one effective way in
which community space could be used for dual functions.
The garden space is not only utilized for social interaction, it is also a productive
garden where fresh herb, fruits, and vegetables are grown. 60 Richmond East has
been designed to consider the occupations of the resident group. The elevated, linear,
productive gardens eventually supply food for the restaurant and training kitchen on
the ground floor. The organic waste from the restaurant is compost and is re-used as
nutrients for the garden, making it a small-scale full cycle ecosystem. Other spaces
such as classrooms, conference halls and amenities support social activities and
interactions, as well as offering opportunities for the residents to share and exchange
their skills and knowledge.
43
A ventilation stack effect has been created in the building to eliminate the need
for air conditioning. The building is made up of 60% solid matter, with mostly insulating
fiber cement panel cladding, and 40% glass. The green roof also minimizes the gain
of heat island effect. 60 Richmond East demonstrates how social housing and food
production could be planned concurrently in the present urban conditions. However, the
limited amount of green space in this model can only contribute to a small scale of food
production.

This section focuses on the three food-oriented theories. The three distinctive
models are theoretical-oriented, conjectural-oriented, and factually-oriented. The
first model is the Continuous Productive Urban Landscape (CPUL), developed by
architects Katrin Bohn and André Viljoen, using an interlinking strategy to connect edible
landscapes in urban areas as a green infrastructure network that is spread across
the city. The second model is Vertical Farming developed by Dickson Despommier.
Agricultural production in a vertical format will not only solve food shortage issues but it
also fits appropriately into the urban setting. The third model, the Food City developed
by architects MVRDV and Why Factory, proposes a systematic approach to estimate
food produced and consumed. These methods will collectively help qualify and quantify
parameters to design Agri-town.
47
Figure 3.4.1 - Vertical Farming Proposal & Water System
need for pesticides, fertilizers, and herbicides is eliminated. The food miles and hence
dependence on fossil fuels could also be reduced drastically (Despommier 2010).
Vertical farming facilitates food safety and security. It also prevents crop
loss due to shipping or storage, thus improving food adequacy. From the social
perspective, vertical farming provides employment opportunities for the local residents
as they actively participate in their community’s efforts to create a sustainable living
environment. (Despommier 2010).

yield and space-efficient method in this instance. In Western Europe and North America,
urban agriculture takes the form of urban farms, community gardens, or allotments
(Viljoen, A., Bohn, K., & Howe 2005).
The Food City is an experiment proposed by MVRDV with the Why Factory in
response to the current food crisis. The model estimates the food mass that an average
person needs for a year, the land required to grow all of the food for that person, as well
as the requirements for livestock and its feed and laydown in a flat area. The model
has also shown that significant diet changes take place based on available land area.
In the United States, for example, areas where people consume a lot of beef require
about double the area of land to grow animal feed, compared to that of Japan. The
Food City study used the city of Hangeul in Netherlands as an example to test whether
urban agriculture would be feasible as an application. The proposal has been tested in
2 formats: first, by occupying all available vacant land, the city would require about 41.5
storeys to grow all of the necessary food to feed the city. In the second format, tower
formations, the city would require multiple towers as tall as 35km. The conclusion of
the experiment is that it may not be feasible for a city to achieve total food self-reliance.
Although Food City is just an experiment, it provides a framework and outlines the
factors to consider when executing an estimation of food consumption, as is done in the
following chapter.

This chapter is divided into three parts, each addressing the general standards
and measurements pertaining to food, farm and housing. The following data is
intended to establish a set of typical rules and design criteria for incorporating food,
farm, and housing together as building typology. It is interpreted to demonstrate how
this concept could improve food security, productivity and living conditions in order to
ensure healthy food access, self-grown food to offset food expenditure, and provide
opportunities for cultural exchanges for the low-income groups living in the city. Sections
4.1– Food Consumption, 4.2 – Food Types, and 4.3 – Food Servings determine the
quantity and quality of crops and livestock to be consumed and produced, based on
dietary recommendations. Ensuring the right amount and types of food promotes the
individual’s health. Sections 4.4 – Farm Yield, 4.5 – Farm Types, and 4.6 – Farm Sizes
address conventional farming and determine what new possible farming methods and
technologies could be implemented. Sections 4.7 – Affordable Housing Types, 4.8 –
Affordable Housing Unity Sizes, and 4.9 – Affordable Housing Program, assess the
current low-income housing designs and structures, laying out possible modifications,
adjustments and improvements.
52
4.1 Food consumption
Food consumption is the first determinant that influences building design, and
is concerned with food, farming, and housing. The daily food consumption of a person
is measured in terms of energy intake. The unit of energy in the International System
of Units (SI) is the joule (J), and large amounts of energy are measured in kilojoules
(kJ = 103J). However, nutritionists and food scientists use calories and kilocalories to
measure food energy in a regulatory framework. The conversion factors between joules
and calories are as follows: 1kJ is equal to 0.239 kcal, and 1kcal is equivalent to 4.184
kJ (FAO 2002). The mass of food is expressed in grams (g). Food contains multiple
components that provide energy to body; the main components are protein, fats and
carbohydrates and other components, which include alcohol, polyols, organic acids and
vitamins and minerals (FAO 2002). The number of calories contained in a unit varies
from component to component within food. For example, the energy value of 1 gram
of carbohydrate is 16 kJ (4 cal); 1 gram of fat is equivalent to 37kJ (9 calories); 1 gram
of protein provides 17kJ (4 calories) and 1 gram of alcohol contains 29kJ (7 calories)
(Otten, Hellwig, & Meyers 2006).
The nutrient ratio is fairly similar across genders and different age groups; the
proportion curve does not change. Only the total food consumption per individual varies,
depending on geographic location, ethnic background and eating habits. Individual food
consumption in developed countries is usually much higher than the consumption for
people living in the developing countries. However, the required intake could be similar;
perhaps there are omissions in the available data regarding wasted or excessively

consumed food. In general, the required calorie intake per day has a significant increase
from the stage of childhood into teenage years. After the age of 18, or upon reaching
adulthood, the energy requirement gradually decreases with age. For children, women
of childbearing age and men and women over 50, it is vital to ensure proper nutrition
(Health Canada, 2007).
As stated earlier in this chapter, an active male requires an average total of 2441
calories intake per day (890,965 calories per year), and an active female requires an
average of 2016 calories intake per day (735,840 calories per year) to acquire enough
energy to perform typical daily activities. Using the annual average intake per person,
the amount of food that needs to be grown for a person can be determined. In later
sections of this chapter, in-detail analysis of farm sizes will be conducted to calculate
the area of cropland required per head.
54
4.2 Food Types
This section determines the possible food types that can be produced in sufficient
quantities within the City of Toronto to establish food availability and accessibility during
different seasons. As well as the quantity of food, the quality of food is essential to
an individual’s health. One healthy meal should include a portion of each category of
food—vegetables and fruits, grain products, milk or alternatives and meat or alternatives
(Health Canada 2007). This is explained in detail in the food-serving chapter. The ideal
scenario is to grow and harvest all four types of food within a property. However, this
may not be feasible and one needs to identify what can be grown under the climate
conditions.
55
Figure 4.2.1 – Ontario Availability of Food Groups and Greenbelt
time frame of 6 months or more within the region are: bok choy, carrots, cauliflower,
mushroom, onions, potatoes and rutabaga in the vegetable group, and apples and
rhubarb in the fruit group (Foodland Ontario 2010). Further, some vegetables that can
be easily grown in a greenhouse environment are cucumbers, lettuce and tomatoes.
Chicken, duck, geese, and goat are the common livestock and poultry in the region. The
breeding and gestation periods for these cover two seasons (England 2007). Therefore,
choosing one of the mentioned animals for a domestic diary/poultry farm, egg, meat
and dairy product supply can be ensured for a certain period of time for each year. The
chart shows that there are food items from each 4 major categories that can be made
56
available locally for more than half of a year. This way, the food and nutrient supply for
each individual in a household can be secured by better managing of food cultivation.
Apart from climatic constraints and weather conditions, which dictate all types
of agriculture productions, the most challenging part of urban agriculture is finding
open spaces to grow food in a city with high population density. Finding spaces to grow
vegetables and fruits is relatively easy, as these are more flexible in size and scale
requirements. However, it is more difficult to accommodate animal, livestock, feedstock
and farming equipment, as land values in urban area are very high. In summary, the
food items possible to be grown locally within individual residential spaces are bok choy,
carrots, cauliflower, mushroom, onions, potatoes and rutabaga, apples and rhubarb.
Chicken and duck farming can be incorporated for dairy, egg and meat in control
conditions. The items that could be grown in indoor spaces are cucumbers, lettuce, and
tomatoes. However, further investigation is needed to determine whether these food
choices alone could make a good serving for an individual’s health.
Much like calorie intakes, the definition of a good serving varies depending on
individual‘s age, height, weight, gender, and activity levels as well as genetics and
body consumption (Health Canada 2007). The healthy food pyramid (see Figure 4.3.1)
shows the food products and the proportion of different food types a person needs to

eat per day in order to stay healthy. One should eat more foods from the bottom part of
the pyramid, such as vegetables and whole grains products, and less from the top such
as red meat, sugary drinks, salt and refined grains. A certain amount of alcohol and
additional vitamins might be necessary for some people as optional or supplemental
products, but are not applicable to everyone (Willett, Skerrett, Giovannucci, & Callahan
2001).
The quantity of food servings is calculated differently for each food item. Food-
measuring units are expressed in milliliters and grams. The quantity and the number
of servings in the recommended chart guide are determined based on the volume
contained per serving cup(s). Each serving of vegetables is equivalent to 125 milliliters
(mL) or half a cup, 1 serving of meat is equivalent to 75 g and 1 serving of fruit is
equivalent to 1 fruit in quantity (see Figure 4.3.2).
Following the recommended food guide will help meet the daily-required intake
for vitamins, minerals, and other nutrients. In addition, eating well could reduce the risk
of obesity, Type 2 diabetes, heart disease, certain types of cancer and osteoporosis,
60
and contribute to the individual’s overall health and vitality (Health Canada, 2007).
However, males and females require different amounts of food servings per day, as
do children, teens and adults (see Figure 4.3.3). A typical adult male between the age
ranges of 19 to 50 needs 8 servings of vegetables; 8 servings of grain; 2 servings
of dairy and 3 servings of meat per day. Converting to food volume and mass, this
amounts to 1000mL of vegetables, 1000mL of grain, 250mL of dairy and 225g of
meat each day. A typical female in the age ranges of 19 and 50 needs 7 servings of
vegetables; 6 servings of grain; 2 servings of dairy, and 2 servings of meat per day.
When converted to food volume and mass, this equals 875mL of vegetables, 750mL of
grain, 250mL of dairy, and 150g of meat.
For practical purposes, (since 1mL of water has a mass of 1 g, let us assume
similar density for all the food types) we may conclude that a male Canadian needs
to consume about 2475g per day (903,375g per year), and a female Canadian needs
to consume about 2025g per day (739,125g per year) (see Figure 4.3.4). With this
information, the arable area each person needs to secure for food production so that his
or her food requirements can then be determined.
61
4.4 Farm Yield
The quantity and quality of food per person have been determined in previous
sections. The following section will address the yield for each local food type in order
to estimate the area a person would need to secure for food production to meet their
daily and annual energy intake and volume of food. Each food item requires different
amounts of space to grow and to process. The area considerations for the growth
and harvest of vegetables, fruits, grains and livestock differ from species to species.
This section will use a number of charts as reference to explain the growth and time
requirements for each of the food types that are cultivable in Ontario through the
conventional agricultural method of field growing and harvesting. This guide will provide
rough estimations of area that one needs to reserve in order to grow multiple foods
within the city, that will meet the energy intake and amount of food required per person.
The reference charts are separated according to their food groups. For
vegetables, fruits and grains, each label identifies the common and biological name,
class, seeding season, time to maturity, harvest period, water requirement level, ratio of
calories input and output, as well as conventional yield, from top to bottom respectively.
In a similar format for livestock and poultry, each label identifies the common
and biological name, class, breeding seasons, gestation period, time to maturity,
temperature, ratio of calories input and output, average water requirement, and average
feed requirement (see Figure 4.4.1 to 4.4.4).
Food production under Canada‘s cold climate could start in early February, and
plants could be transplanted easily from outdoor to indoor and vice versa throughout
different seasons (Tracey 2011).
62
Based on prevailing conditions, the potential for including livestock in urban agriculture
is relatively low. This is because their water consumption, feedstock, nutrient, and waste
storage require ample space and energy. In addition to the space required for growing
crops, animals also need space to exercise. Thus, poultry like chicken and ducks, which
are small in size and require the least amount of water and food per day, are the easiest
livestock that can be included in domestic farming.
In this section, the required space and yield for each agricultural product that is
available in Ontario are determined. This data can further be explored to compare
between the productivity of the conventional field lawns growing method in the rural
areas and the compact growing method in the urbanized districts.
Making the assumption that an adult male and an adult female will eat only rice in a
year for every meal, to produce the amount of rice to cover all the energy for their daily
activities, the male requires 477 m2 of growing space and the female requires 395m2 of
growing space (see Figure 4.4.6).
However, in order to calculate the required growing area with multiple crops for each
person, both the food mass and the ratio of caloric input and output of the crop item
must be taken into consideration. If we consider only the overall average of food mass,
the answer will be inaccurate with figures either over or below the food energy level
standard for each person.

4.5 Current Agricultural System
The current agricultural system for a city resembles a unidirectional flow from
the rural zone to the urban core (see Figure 4.5.1). Food and waste travel the same
distance before they are processed. Thus, the current system and processes end up
adding food miles and greenhouse gas emissions as the city expands. Agricultural
Urbanism is a theory that proposes to bring all the agriculture processes into closer
proximity. Here, food serves as the prime infrastructure element that connects the
various activities together. The idea of agricultural urbanism may be applied to
different scales and sizes of food production zones along the transect. The concept of
agricultural urbanism is subdivided into 3 streams; extra-urban agriculture, peri-urban
agriculture and intra-urban agriculture (see Figure 4.5.2). The flow of product and
processes will emerge from both directions and food production and waste treatment
will take place locally in both the rural and urban zones.
In order to investigate the idea further, a simple study (see Figure 4.5.3) is
conducted by comparing the different zones along the transect proposed by Andre
Duany. The objective of this study is to determine how urbanization affects arable
space by estimating the maximum productive surfaces and planes based on a typical
100 meter by 100 meter block on each zone along the transect. The determinants are
categorized into building coverage, building footprint areas, service and road area,
69
productive coverage and total productive surface area. These are estimated by adding
building façades, open spaces and side walks within the block. The findings of this
experiment suggest that the agricultural opportunities of a site increase in correlation
with its density. This proves that agricultural production can co-exist with spaces
for habitation without any conflicts. The concept of vertical agricultural urbanism is
subdivided into 3 major areas as follows: low-urban agriculture, mid-urban agriculture,
and high-urban agriculture (see Figure 4.5.4). If different zones are stacked and mixed
together in three different directions on each floor, the level creates its own microclimatic
conditions, which are suitable and controllable for a variety of different programs and
growing strategies.

5.0 Design Proposal
Firstly, for the urban scale design investigation, the factors being considered
must be evaluated for viability vis-à-vis the low-income population as well as the total
population of Chinatown. The design will proceed by first following the Food City
estimation method and then will use the nutrition and yield information determined in
Chapter 4 as a reference guide to estimate the food energy intake, food mass, food
choices and required area for agricultural production.
Finally, for the building scale investigation, the focus is to develop a sustainable
closed-loop system incorporating elements from the different sustainable systems
discussed earlier. The model illustrates how food production and housing could be
integrated within a building design, to conclude the Agri-town research.

5.2 Site Selection
The site chosen to test the research is the Alexandra Park neighbourhood in
Toronto’s Chinatown district. The site is bounded by Dundas Street West and Queen
Street West in the north-south direction and Augusta Avenue to Cameron Street in the
east-west direction. This site is one of the locations selected to implement the new
revitalization plan.
The current master-plan addresses the issues of housing shortages and the
dire need for building repairs. However, the large numbers of low-income families and
households that are going to move in to the Alexandra Park neighbourhood require
the supply of basic necessities, especially food. In order to prevent urban poverty and
slum-like conditions to take place in this redevelopment, it is necessary to develop an
infrastructure system oriented to food. The infrastructure system must be designed
in such a way as to support the large amount of residents with food, shelter and job
availability.

The current Alexandra Park neighbourhood has adopted typical town planning
principles observed in the suburbs. Due to inaccessibility along the street edges, the
site has become isolated, separating the community physically and socially from the
rest of the city fabric and major roads. Vanauley Street and Vanauley Walk have isolated
the site, preventing direct north-south access with their meandering structure (see
Figure 5.3.1 & 5.3.2). The streets in between Spadina Avenue and Bathurst Street,
running in an east-west direction, only make ambiguous connections with the city block.
Furthermore, the lack of social presence and lively activities on Grange Avenue, Carr
Street, and Wolseley Street have created an impression of an encroaching Community
Center and school. The inconvenient approach has kept people from fully using the
facilities and services of the Community Center. Therefore, a new infrastructure system
needs to be implemented in order to improve the current urban condition and connect
important junctures and neighbourhoods within the city (see FIgure 5.3.3 & 5.3.4) .

Agricultural urbanism, as the core strategy in the design development, will not
only benefit the residents living in the new Alexandra Park neighbourhood by offsetting
food expenses through growing their own food, it will also support other food-related
industries beyond Chinatown. Its benefits will also affect the financial district and other
downtown areas of the city. Placing food at the core of the program organization and
system approach, the closed loop system would develop from considerations of how
food is produced, processed, transported, stored, distributed, consumed and celebrated.
Waste recovery would complete the sequence of the closed loop sustainable system at
the individual, community and urban scales.
83
5.4 Zoning and Connectivity
22 o
As optimization of local food production is one of the major goals of this design
experiment, new zoning should focus on taking full advantage of natural resources,
particularly natural daylight, and simultaneously, should push the boundary to increase
site density. The orientation of the sun angle for Toronto is approximately 70 degrees
Celsius in the summer and 22 degrees during winter. If we apply the winter angle
throughout the site as the zoning requirement for building design, the height differences
of the volume, starting at ground from the south phase, incrementally progress to the
tallest point of the north phase at 150 meters (see Figure 5.4.1).
Further, cutting out the street grid and terracing of the volume would prevent
over-shading issues for the building complex. In addition, these moves would create
courtyard spaces on each plot for balconies towards the center, as well as extra edible
surfaces for food production and circulation. Carrying on with the principle of continuous
edible landscape, Grange Avenue, Carr Street and Wolseley Street will be extended
84
Figure 5.4.1 – Zoning and Massing
east-west from Bathurst Street to Spadina Avenue. They will be widened and dedicated
to become a 15-meter farm strip with bike paths and pedestrian trails. Furthermore, this
will connect the Community Center and school in Alexandra Park and Randy Padmore
Park with the rest of the city.
In addition, it is suggested that the parking lot at the intersection of Augusta Avenue and
Wolseley Street could also contribute to the food system as well as improve connectivity
throughout Alexandra Park in east-west direction. In the north-south direction, Vanauley
Street will be widened to 40 meters and developed as a promenade with sufficient
spaces reserved as temporary venues for events, with the landscape component acting
as a spine anchoring the design. This would improve connectivity and alleviate the
site isolation. Augusta Avenue and Cameron Street would become the service streets
with entrances for loading and parking underground, to facilitate the transportation and
delivery of food from the site to the stores and restaurants along Spadina Avenue.

Agritown has adopted an interest-based model similar to that learned from the
Broadacre city and Phalanstere as a social structured model. The development is a
type of co-operative housing in which all the residents carry a social responsibility and
social duty of contributing to the overall farm productivity and yield. With this mandate
becoming a part of their daily jobs and leisure activities, this model resonates a cultural
movement like that of the Victory Gardens during the World War periods. Each unit
is a simple rectangular volume with the dimension of 4.5 meters in width; 9 meters in
depth; and 4.5 meters in height. The total floor area of each unit is 81 square meters.
Surfaces within the units are subdivided into 3 distinct spaces with a collective of
residential (60.75 m2), commercial (20.25 m2), and agricultural (324.2 m2, maximum)
compartments provided, including balconies, front yard, a rooftop and courtyard spaces
(see Figure 5.5.1).
88
In the current design, 2906 units can be provided. Another 560 units could
be provided, in addition to the original masterplan proposed by Toronto Community
Housing Committee for the same site. If the density and amount of units are to be
maintained, the additional areas can be turned into open-air and enclosed community
gardens, as well as hydroponic and aeroponics greenhouses, contributing to the overall
agricultural production of the site. This would provide extra amenities spaces within
the buildings, thus encouraging the exchange of knowledge and interaction amongst
residents.

5.6 Circulation Loop
The main circulation system of Agritown is based on a loop system. The network
consists of a series of ramps that are linked together into a single barrier-free corridor,
where people can circulate from the grade level at the south end of the Queen Street
entranceway, and travel along this path to reach the rooftop garden of the towers,
located at Dundas Street on the north. The terracing and sloping of the buildings’
volumes create two routes, with an outdoor ramp and an indoor ramp. As the ramps
wrap around the perimeter of the plot, they create different vistas from within, offering
interesting views and varying experiences in all directions along their journey. The
corridor’s width of 4.5 meters is consistent throughout the whole system. With the
clearance height of the ceiling at 4.5 meters, the inner side of the ramp becomes an
indoor strip mall where people will pass by the commercial components of each unit.
These commercial spaces become storefronts on the inner surface of the corridor.
Each unit will be converted into different working spaces and stores depending on the
residents’ skills or household interests.
92
Figure 5.6.2 - Residential Units
On the outer side of this corridor, towards the exterior, the building façade has
incorporated hydroponic tubes for the growing of vegetables and plants, such as lettuce
and bok choy. The walking surface is a green lawn with fixed planters and movable
trays, to allow growth of a variety small-scale food crops, such as chilli peppers and
tomatoes. The transitional spaces between each turn of a ramp are areas that are
used as nodes within the loop. These nodes become significant hubs of interchanging
functions, accommodating a mix of animated programs similar to that of the Public
Farm 1 project. In addition to the generous airspaces in this circulation system, the
lush greenery provides a human-altered landscape in the city that uses food as
the alternative to typical landscaping material such as trees, grasses and flowers.
Furthermore, the food hydroponic façade on the outer boundary functions as a natural
shading device.

The entire loop system serves various functions including a greenhouse and
a continuous linear park. Similar to the Wynchwood Barn and Evergreen Brickworks,
Agritown’s circulation is a complex and diverse system composed of farm, market, retail,
office, social, and recreational activities. Functions of daily life in work, play, growth, and
eating are fully compacted and integrated as a holistic integrated system.

5.7 System Integration
The transportation, storage, distribution, and waste recovery of the food system
typically stretches along an entire transact from the rural to urban core. Agritown has
attempted to integrate these systems together by organizing them into layers within the
site.
The rooftops of each of the buildings will be integrated with storm water collection
tanks. Through the façade system of water pipes, sprinkler heads and metal, the storm
water is filtered and cleansed by way of the looped ramp system. The vegetables will
also contribute to the filtration system, cleansing while being irrigated at the same time.
The greater the distance the water travels through the hydroponic system, the cleaner
the water will become. Therefore, the 400m-long water channel along Vanauley Street is
very clean and safe for people to swim in during the summer and doubles as a skating
rink during the winter.
102
Figure 5.7.2 - Vertical Circulation + Distribution System
The building envelope of the towers’ façades will integrate photovoltaic films in
between the layers of glazing. The building rooftop will also be dedicated for hot water
solar panel systems that will harvest solar energy to provide additional shading of the
interiors as well as generate electricity for the dwelling units.

Figure 5.7.4 - Social + Recreational Area
The rooftops of the midrise buildings are programmed for grain and corn
production. The elevator cores, besides serving use by residents, will provide extra shaft
spaces for distributing the harvest to the basement level where they will be processed.
After processing is complete, the crops are stored in another shaft. These vertical shafts
act like silos, storing food crops within the vertical distribution system for Agritown.
These shafts will be also linked with the loading corridor along Augusta and Cameron in
order to distribute food to further locations in the city.
106
Figure 5.7.5 - Technical + Service Area
To accommodate for waste treatment, the basement levels on each plot will have
a series of incinerators as part of the mechanical system to process methane from both
human and food waste. The waste is reused and regenerated into energy, supplying
electricity for the neighbourhood. This method is an example of repurposing waste as an
input resource and regenerating nutrients as the output resource.

Conclusion
First of all, Agritown bases its estimates on the target population that needs
to be fed. It has been found that an average Canadian requires about 2100 square
meters of farmland to grow all the food that meets their annual energy and nutritional
requirements.. The research explored whether livestock and meat processing is feasible
on site and found that, for this specific design, livestock such as cattle and pigs need to
be eliminated on account of space constraints.
Secondly, In the Agritown proposal, each suburbia style units with 81 square
meters of floor area could provide about 324 square meters of surface area dedicated
for food production. With the amount of surface area available, the unit can produce
about 1.2 times an individual’s annual vegetable and fruit consumption (272.8m2). If the
unit is only designed for one person, this could in result cover 12% of his or her total
annual food expense. However, if each unit accommodates a family, more service areas
need to be discovered, as all the interior flooring, wall and ceiling areas will be fully
dedicated to food production. This also raises a further question as to what is the most
ideal and effective building geometry and orientation for food growing in urban areas.
Since this investigation applies to vertical agricultural urbanism, a simple rectangular
structuring has been found to be the best match to farm effectively and efficiently.
Thirdly, Agritown suggests the relationship between space and the location for growing
different types of food. Further investigation is required to evaluate how much energy
is required in order to produce the targeted quantity of food. If technical systems
and material selection could be better integrated, it is expected that factors such as
material properties and lighting illuminations can have a positive effect on a household’s
expenses on energy and utilities. This could further enable them to make savings from
food expenditure and rent.
114
In conclusion, Agritown as a Utopian experiment integrates the parallel systems of
agriculture and housing development closer together. It systematically develops the
argument that both agriculture and other activities could share the same spaces and
take place simultaneously without conflict. . Further, Agritown provides a model by
whereby food system and living spaces could coexist in the urban areas of a city,
offsetting a portion of food expenditure and housing shortages for the low-income
demographic. Vertical agricultural urbanism thus provides precisely the solutions the city
needs in order to solve the problems of food production and housing due to population
growth and city migration that a city will continue to face in the future.

Appendix - Food Cost Calculation
How to Calculate Your Food Costs Using the Nutritious Food Basket*
Follow the steps below to find out the cost of a weekly nutritious
food basket for your household.
Table 1

Gender/Age (Years)
STEP 1: Week
Write down the age and gender of all the people you are 2–3 $21.91
feeding. For example: 4–8 $28.24
Man, 37 years old and Woman, 37 years old 9 – 13 $37.44
Boy, 15 years old and Girl, 8 years old
14 – 18 $52.75
Males
STEP 2: 19 – 30 $50.92
Refer to Table 1 to find the cost of feeding each person. Write 31 – 50 $46.04
down the cost of feeding each person. 51 – 70 $44.49
Over 70 $44.03
STEP 3: 2–3 $21.49
Add these costs together to find your subtotal.
4–8 $27.39
STEP 4: 9 – 13 $32.08
Since it costs a little more to feed a small group of people and 14 – 18 $38.29
Females
less to feed a large group, the total weekly cost may need to be 19 – 30 $39.43
adjusted using the following factors: 31 – 50 $39.01
Household Size Adjustment Factor 51 – 70 $34.61
1 person multiply by 1.20 Over 70 $33.98
2 people multiply by 1.10 Pregnant 18 & younger $42.68
3 people multiply by 1.05 Women 19 - 30 $43.08
4 people make no change
5-6 people multiply by 0.95
31 - 50 $42.04
7 or more people multiply by 0.90 Breastfeeding 18 & younger $44.46
Women 19 - 30 $45.67
STEP 5: 31 - 50 $44.63
To determine the cost per month, multiply by 4.33
*The cost of the Nutritious Food Basket is based on the 67 food items collected from 12 stores across the City. The software program
automatically adds 5% to the basket cost to cover the cost of miscellaneous foods used in meal preparation, e.g. spices,
seasonings, condiments, baking supplies etc.
