Guiding the evolution of the food system in NYC
The current food system supplying food to the residents of NYC is outdated and
inefficient. Much of the food eaten in the city is transported in from far off places such as
California, or from Florida in the case of bananas. The system was by and large a side-effect of
the industrial revolution, when companies started to mass produce foods in certain areas and
transport them all over.1 This type of food system is what helped America produce enough food
for all of its citizens in the first place because it was a convenient.
However, at the same time it is convenient, it is also a less than ideal method of providing
food. By the current food system, chemicals have to be used to support the mass production of
food. Also, because food is transported such long distances to get to the market, not only is the
freshness of the produce being degraded, but also the environment because of the fossil fuels
consumed during the transportation process. A more regional food system, which would cut the
number of “food miles” needed to transport foods to NYC markets, would be much more
efficient and environmentally friendly.
In order to gauge the effectiveness of the current food system in NYC and to compare
this system to show how a regional one might be better, I created a five-day food plan and
estimated the costs of buying food for three of the five days. I later compared the nutrition in the
food plan with my nutritional needs.
1 Overview of the Global Food System
My nutritional needs were determined by taking into account a variety of factors: my age,
weight, and physical activity level. At the moment, I am 17 years old, weigh 150 pound, and am
6 feet, or 72 inches, tall. Using the basal metabolic rate (BMR) formula for men, which is 66 +
(6.3 x weight in pounds) + (12.9 x height in inches) – (6.8 x age in years), I calculated my BMR
to be 1824 calories. After the basal metabolic rate is calculated, a multiplier, based on my
activity level, needs to be applied. For my specific activity level of being lightly active, which
consists of my walking everywhere and going to the gym three days a week, this multiplier
amounts to 1.3. In the end, my caloric needs amount to 2371 Calories per day. 2
In addition to calories, I also need to consume protein, carbohydrates, and fat. The
recommended daily allowance of protein intake for my exercise level is 0.5 grams of protein for
every pound I weight, totaling my protein needs to at least 75 grams a day.3 Carbohydrates
should be 45 to 65 percent of caloric intake, so I need at least 267 grams of carbohydrates every
day. Finally, fats should be around 25 to 35 percent of caloric intake, meaning I need at least 66
grams of fat every day.4 I decided to use the above guidelines because they are the official
Recommended Daily Allowances as specified by the U.S Department of Agriculture. After
calculating these nutritional needs, I charted a five-day food plan:

The food plan for the week did not match up with my nutritional needs. It was severely
lacking in terms of calories, with me only meeting 80% of my requirements for daily caloric
intake, and consuming not as much protein, carbohydrates, or fats as I should be. This was a
direct result of not eating enough food every day. To make up for this nutritional deficiency, I
could eat more snacks, such as grapes, throughout the day. Each serving of grapes already
provides a good amount of calories and carbohydrates. This, combined with its “popcorn-like”
nature would make it easy to gain back some of the lost calories. I can also eat another meal
altogether on top of this. In a given day, I generally only eat three meals: breakfast, lunch, and
dinner. If I were to eat another, slightly smaller than normal, meal in between lunch and dinner,
perhaps right after school, I would be able to consume the recommended amount of calories,
protein, fat, and carbohydrates every day.
After the food plan was drawn up, an estimate was formed for the food costs of three of
the days, taking into account the individual ingredients of each food during the days. Afterward,
the foods were priced out at three food markets in TriBeCa: Whole Foods, an organic food
supermarket; The Food Emporium, a supermarket; and Morgans Market, a local deli. The
following charts show the prices of food per day:

As would be expected, the price of food for three days was most expensive at Whole
Foods, with the average total cost equaling $12.57 per day. The Food Emporium, a local
supermarket, came in second, with an average cost of $11.49. Finally, Morgans Market, a
convenience store, came in a close first place in terms of least expensive food, with an average
cost of $11.47 per day. Although food costs are cheaper at the local convenience store, Morgans
Market, than at Whole Foods or The Food Emporium, it is not the ideal place to buy food from.
The food at Morgans Market is very cheap because it is mass-produced with government
subsidies and very processed, and then transported from a far off place. By the time the food
items hit the shelves at the convenience store, it is no longer fresh, making it a less than ideal
source of food for healthy living. The healthiest way to eat and buy food is to eat locally.
In New York City, the most local way for people to get food would be to look within the
very Community District that they live in. Though this is the most local way to get food in NYC,
it is also the most unsustainable.
New York City Community District 15, which is located in Brooklyn, has an estimated
population of 159,650 people as of the last census in 2010. The ideal ratio of local grocery stores
to people is 30,000 SQ FT / 10,000 people. At the moment, community district 15 does not meet
these golden standards, and is even below the citywide average ratio of 15,000 SQ FT / 10,000
people.5 Most of the community districts in Brooklyn are below
the average ratio, and a majority of the community districts in all
of New York City are below the golden ratio of local groceries to
people. Though it is slowly on the way to meeting those
standards, with the recent openings of several grocery stores in
the neighborhood as a result of the FRESH initiative, which provides “discretionary tax
incentives” to grocery store operators in neighborhoods all throughout New York City,6
including in Community District 15, this lack of food markets in New York City to even provide
food in the first place shows how unsustainable a community-district based food system is.
If more grocery stores were to open up in this district, there would also need to be enough
food to support them. The best way to supply local stores would, of course, be with local foods.
This would make Community District 15 self-sustaining as well as help it meet the ideal
standards as set forth by the NYC government. Although there is not much food being grown in
the district at the moment, a way this goal can be accomplished is by converting vacant lots in
community gardens, as well as encouraging the growth of rooftop gardens on top of the many
flat-roofed buildings in the district. Though these methods will replace some of the processed
and transported food currently being sold within New York City, it is, in the end, still
5 Going to Market6 2013 New York City Food Metrics Report
unsustainable to adopt a community-district based food system because there is not enough
farmland in the city to feed all 12 million people living in it.
A larger local food would be all of the farmland in the state of New York. Farmland New
York State covers about 3.15 million hectares—areas of land covering 1,000 square meters, or
the size of half a football field. Each hectare of farm land in New York produces about 2.58
metric tons of food in a year, meaning approximately 8,127,000 metric tons of food can be
produced at most in a year. This pales in comparison to the 16 million metric tons of food that
the population of New York City needs to eat in a year.7
However, the above numbers, and thus, the calculations above, assume that every person
living in New York City consumes the recommended amount of food every year, although this
may not be true. They also assume that everyone is consuming vegetables and other healthy
foods for nutrition, although many of the calories and foods Americans consume today come
from high-density sources. A study by the USDA in 2003 showed that the majority of Americans
across all age groups and genders consumed more than the recommended daily intake of fat
every day.8 Since fat intake brings in much more calories than do more nutritious sources of
food, they take up much less space, potentially lowering the 1.25 metric tons of food the average
person needs to eat in a year by a large amount. A third and final factor that is not included in the
calculations is the potential use of community farms and rooftop gardens. Although the amount
of farmland and food they provide is not very significant, they can still provide food for some
New Yorkers that would otherwise be have to be transported in.
This transportation of food is necessary because there are far too many people in New
York City for the farmland only in the area of New York City to feed. Not all of the open 7 Why We Transport Food: Feeding the Big Apple8 Factors Affecting the Macronutrient Intake of U.S. Adults
farmland in New York is used, either, necessitating the transportation of food even more. Also,
even if there was some way New Yorkers could survive off of only food grown within the state,
they would probably get bored by the lack of variety in their diet. New Yorkers, and likewise,
urban food shoppers all over the country, have grown accustomed to having every kind of food
available to eat during every season of the year, though some foods may actually not be in season
at the time. Without importing food to NYC from far off regions like California, or Florida,
where in-demand fruits and vegetables may be in season, supermarkets, grocery stores, and the
like would miss out on potential profits.
It has been shown above that, even if New Yorkers
were to not care about getting foods “in season,” and
decided to limit their diet to foods grown within New York
State, there would not be enough food to feed them all. A
third, most ideal way to regionalize food would be to
localize food in New York City to that which is produced
and processed to the region within 200 miles of the city. Within this area, food can still be grown
and brought to market in a matter of hours, keeping the food fresh and locally grown.
The area within 200 miles of the New York Metro Region encompasses multiple
hardiness zones9—geographically classified areas which are used to determine what types of
plants can be cultivated in a particular area, as defined by their minimum average winter
temperatures.10 More specifically, the farmland within this area ranges from 4a to 7b, allowing
9 USDA Plant Hardiness Zone Map10 Hardiness Zone
for a good amount of food variety. The following charts show some of the foods can be grown in
the zones within a 200 mile radius of New York City during each of the four seasons:11

Zones 7-8 Winter Spring Summer FallAsparagus Beans Beets Broccoli Cabbage Carrots Eggplant GarlicLettuce Okra Onions Potatoes Sweet Potatoes PumpkinRadishes Spinach Tomatoes Watermelon
As shown in my previous food plan, the foods I generally eat potatoes, bread, rice, milk,
lettuce, beans, various pastas, strawberries, avocadoes, sweet potatoes, and grapes. In the
regional area that I live in, much of the food I eat can be either grown or produced, with the
exception of avocadoes. Lettuce, beans, and potatoes can be found year-round, except for during
the winter; soy beans to produce soy milk can be grown during the fall and winter; strawberries
are grown mostly during the summer; grapes can be grown during the spring and summer; sweet
potatoes can be found only during the spring.
Although limiting my diet to a local region seems as if it would stifle the variety in my
diet, the variety of hardiness zones around the New York City area actually renders this
assumption false for most of the year. The only foreseeable issue in a regional diet would be the
lack of variety during the winter. As for me, I would be willing to stifle my diet during the winter
in exchange for eating local food because I would be eating more fresh food and supporting
small farmers rather than large corporations.
The above tables
show that there is much
variety in the foods that
can be grown throughout
the year, including, to a
lesser extent, autumn. To
make the food system for
NYC more locally based,
the first step would be to
shift the production of foods to areas within the region. The next step would be to design an
infrastructure to transport food from farms to markets. Luckily, thanks to the Interstate Highway
system, an infrastructure like this is already in place and in use today as a supplement to rail and
air food transportation.12 Also, even without the use of trucks, the transportation time from New
York City to any place within 200 miles of NYC is at most a 4 hour drive. This short distance
reaffirms that fresh, locally grown food is superior to supermarket food because local food can
be sold just hours after it is harvested. Locally grown food is also superior to nonlocal food
12 Regionalizing the Food System for Public Health and Sustainability
Figure 1 A map highlighting the food transportation networks in and around New York State
because it is much cheaper to buy.13 Nonlocal food is more expensive because of transport costs
being factored into its price—a fact that only serves to solidify the need to shift to a more
regionalized food system: it would give people more fresh food, as well as giving them more
inexpensive food.

Taking a look at the charts shown above, the average cost per day of food when buying
within a local area of 200 miles around NYC is $9.51, which is significantly lower than the cost
of buying transported food, the lowest of which was $11.47. The primary reason for this lower
price when buying food locally is that there are little to no transportation costs involved in the
process of bringing the foods from farm to market this way.
Looking to New York City’s future, in between now and the year 2050, a local food
system should be adopted. Switching to a this local food system by limiting the production and
processing of food to the area within 200 miles of the New York Metro area will make New
York City a better place to live in overall by ensuring that the city become more self-sustaining
14 Organic Price Report
and that New Yorkers eat healthier, fresher foods while at the same time paying less for this
food.
On the way to this goal, there will many challenges, such increasing the amount of food
markets in New York City so that the locally grown food can be sold to a good amount of
people. The food markets problem is an issue already being addressed today, with the adoption
of initiatives such as the FRESH initiative, which encourages people to start up grocery stores in
the city. Another challenge will be to increase the self-sustainability of New York City itself.
There is not much progress on this issue yet, but some solutions to this goal would be to form
rooftop gardens on the many buildings in NYC. In addition to rooftop gardens, the conversion of
vacant lots to community gardens will also bolster the self-sustainability of NYC.
Once these two challenges are solved, and NYC begins to move towards a more
regionalized food source, the food system in NYC will be on its way to evolving into a healthier,
more efficient, and more self-sustaining one by the year 2050.
