Humans are unique on Earth in that
we live outside of the balance provided by Nature.
In other words, the Lion on the plain does not eat
all the Zebra's, attempt to clone them, or even attempt
to domesticate them. Primarily because they do not
hold the intellectual capacity, but the evolutionary
reason is that Lion's and Zebra's live amongst a delicate
balance of supply and demand. At the point that the
Lion's are eating too many Zebra's the Lions die back
from lack of food. At the point that the Zebra's become
abundant the Lion population increases to reflect
the plentiful food source. Humans do not abide by
this check and balance as our intrinsic population
growth attests to. It is our consciousness and corresponding
ingenuity that sustains and proliferates human life
on Earth- via domestication, research, technology,
breeding, etc. Thomas Malthus recognized this in "An
Essay on the Principle of Population", published
in 1798. This important essay first identified the
geometric role of natural population increase in outrunning
subsistence food supplies. This essay actually prompted
one of the most influential minds in the history of
humanity, Charles Darwin, to ponder and explore the
patterns of evolution. The "Food Movement"
is a phrase we at PG coined to embody the essence
of what we should be focused on in our quest to ensure
that there is Food Security for all people on Earth.

The "Organic
Movement" was an initial step in the realization
that we do not live on the Earth, but in the Earth.
The result of this thinking is the Rule of Return,
IPM's, USDA Organic standards, etc. but is ultimately
insufficient for long term food production on
Earth because the focus is on the health of the
soil, not the nutritional value of the end product.
The resulting nutrition is simply a positive benefit,
or simply taken for granted. For example, in his
book "The Origins of the Organic Movement"
Philip Conford states, "Organic farming is
not about rejection; it is about positive acceptance
of the natural order and the intention to work
within its laws (16-17)." Or completely separate
right? The misconceptions regarding hydroponics
are so |
pervasive that
the "organic" community is blinded by self-bias
in "rejecting" the merits of this technology
regarding food production out of hand. The "Organic
Movement" is an offshoot of the general understanding
that synthetic fertilizers do not encourage the synthesis
of natural systems. People came to realize that unless
we harnessed and utilized natural biological systems
we would lock out and mute the systems that have served
to sustain us from time immemorial. The USDA standards
adopted October 21, 2002 are a step in the right direction,
but have effectively pigeonholed the options we have
for producing and, more importantly, marketing healthy
produce. A pigeonhole is "a specific, often oversimplified
category. An instance where an action prevents further
action, to put aside and ignore; to shelve."
With the best intentions the USDA has done just that.
By maintaining that soil-based growth remain the only
viable means of producing "organic" food
and ensuring the vitality of that foodstuff, our government
has disenfranchised its citizens from a valuable source
of nutritious food and stymied the development of
an amazing and potently relevant industry regarding
human sustainability- the commercial hydroponic industry.
This general mindset is carried into the present day
and is apparent when engaging "organic"
enthusiasts and web logs after mentioning the word
"hydroponics":
"You are
a very nasty person to be thinking that anyone would
not be able to tell the difference between a hydro
growing and harvesting process being completely different
from an organic one, it's easy to tell just by reading
about how they both work." (quote from a response
on soilassociation.org
forum)
Immediately there
is a backlash born of misunderstanding, but also easily
understood. Many of the same fertilizers used in hydroponics
are utilized by Big Ag as field fertilizers. This
backlash is entirely relevant relative to field-based
growing, but not growing in general. Plants are not
concerned with the genesis of their food as much as
humans are. In other words, a phosphorous ion from
"organic" guano is received and utilized
by the plant in the same way a phosphorous ion would
be from a synthetic salt- in an inorganic form. It
is the human condition that heeds the genesis of fertilizer
production, hence "synthetic" or man-made.
These are the same synthetic fertilizers that we are
used to hearing cause runoff problems, such as algal
blooms in lakes and estuaries and fish kills in rivers
and lakes. The keyword here is "runoff".
Too much focus and attention is put on the fertilizers
themselves, not on how they are utilized. A recirculating
hydroponic system elicits no runoff. It is a common
misconception that the results found by implementing
synthetic fertilizers into a field-based growing scenario-
pesticides, GMO's, etc.- are a result of the fertilizers
themselves and that they might be similar to the results
from a properly quantified hydroponic scenario. The
fact is the poor results from field-based synthetic
fertilizer agriculture are due to the inability of
plants to deter pests and diseases due to the weakening
of the biological systems surrounding them. It has
nothing to do with the nature of the fertilizer itself.
This is also why large amounts of harmful pesticides
must be used in the field-based synthetic scenario
in order to compensate for this relative weakness
of biology.
"Well I
personally thought about doing the hydroponic thing
many years ago. They made it sound real attractive
but looking further into it it really didn't seem
real healthy to me. I personally find it hard to believe
that a sollution of anything can provide all the nutrients
that a plant may pull from the soil. I think there
are things that we're not even aware of otherwise
god would have created the plants in our world a little
differently. It's neat how every plant has it's different
requirements and growing areas and still they all
give us something that we need and can use. i'm sorry
I tried the hydroponic tomatoes in the grocery store
but they weren't the same as homegrown which tells
me they lacked something that god provided when he
put them in the soil." (response on organicgardening.com
forum)
|
Here's
another response from an "organic"
forum. The interesting thing here is the comparison
between store-bought tomato's and homegrown
tomatoes.The responder rightly points out that
most tomatoes purchased in supermarkets are
below par. However, they wrongly lay the blame
on hydroponics. The state of tomato taste has
nothing to do with the method of growth and
everything to do with the cultivation techniques.
Tomatoes shipped in from Canada or Israel are
cut green for shipment. They may say "vine-ripened",
but the proof is in the pudding. Without letting
them ripen on the vine all of the simple sugars
and acidic properties that make tomatoes taste
so good are not given a chance to mature. If
you cut Grandma's backyard special green it
would taste like cardboard too. Prove it to
yourself!
Hydroponics
offers a compromise between synthetic fertilizers
and food production. By completely separating
the growing scenario from the ambient environment,
in fact, by creating your own environment, the
negatives associated with synthetic field-based
growing are eliminated. Hydroponics offers recirculating
systems that not only prevent harmful runoffs,
but also use up to 1/20th of the water compared
to traditional field-based growing. In a replicated
or controlled environment scenario utilizing
existing
|
|
buildings or greenhouses
hydroponics also offers the ability to control pest
and disease infestation allowing the plants to grow
uninhibited relative to synthetic field-based growing
scenario described above.
 |
Another
common diatribe hurled at hydroponic technology
is that it is somehow attempting to replace
field-based growing. This is the sentiment that
the Food Movement is trying to overcome. Squabbling
over which method of growing is better than
another is simply wasted energy and results
in detest not progress. Food production is not
a contest. The focus should be placed on the
nutrition and availability of the end product,
not the method of growth or the health of the
soil. If we can combine efforts and work to
make our food production methods and systems
more efficient and harmonious there is hope
for feeding the masses that only become more
prevalent and voracious by the day.
Hydroponics
is "not natural". A statement made
without a proper perspective. Define "natural"-
"produced or existing in nature".
|
Somehow growing
plants outside of soil is equated with genetically
manipulating it, or requiring a lab coat to handle
the "chemicals". Remember, water is a "chemical".
Why is it that we have different standards for "natural"
regarding plant food and plant placement. A plant
is a plant. You can't change what it eats, you can
only enhance what it has to use. We ask you this,
is row upon row of tomatoes, peppers, carrots, broccoli,
etc. growing side by side in your backyard garden
necessarily "natural", or is it "natural"
to see acre upon acre of corn or soybeans on a commercial
farm? Does that "exist" in nature? I mean
have we not reached a point where we can publicly
recognize that the overall efficiency of our food
production mechanisms are due to the passive and active
genetic breeding over generations, use of pesticides,
and harvesting techniques utilizing machines and computers?
Why is it so hard to make the jump to methods of growth
that augment this tremendous progress and eliminate
the pesticides and wastes so as to make it even more
progressive, healthy, and efficient?
Not many years
ago, most of our fresh and processed food was produced
within a 100 miles of our homes. There were hundreds
of local farmers and food processors, each competing
for our business. In those days "fresh"
meant fresh. Local farmers were not as skilled in
the techniques of disguising poor quality. Today,
the process is Big Ag. Local farmers are almost extinct
and are at a disadvantage to large corporations in
that the relative amount of subsidies paid to Big
Ag is astronomically higher and unfair. In fact, 60%
of all farmers and ranchers do not collect any subsidies,
according to the Environmental Working Group, which
cites U.S. Department of Agriculture figures. Among
those that do, the top 20% collected 71% of all subsidies
-- approximately $35,000 a year -- and the remaining
80% received an average payment of approximately $800
a year, according to 2003 EWG findings. Roger Stone,
in his book The Nature of Development, estimates
that industrialized nations spend $300 billion a year
subsidizing farmers (29). We now have larger and more
centralized farms, larger food processors, and larger
chemical companies supplying farmers and food processors.
This results in enormous armies of lobbyists enlisted
to protect these vast sums of money, leaving the little
guy as the loser. There have been estimates that sometime
in the near future 1% of our farms will control over
half our food supplies. Further, over 60% of farm
profits will go to as few as 50 major corporations
(Deutschman,
Gary Sr.). Even if these prognostics are off base,
any trend in this direction does not benefit the end
consumer.
|
|
This
trend is facilitated by the need for more food
from fewer acres attributed to more people and
less arable land.According to the American Farmland
Trust America loses two acres of farmland to development
every minute! But in order to get more using less
in our current state of food production, sacrifices
will have to be made. Among these sacrifices will
be "fresh" food, less control over food
quality, higher food prices, and a much higher
ration of processed food over fresh food. Through
processes such as Food Irradiation and pesticide
use, studies are suggesting an unsettling reality-
we don't know what we are eating. According to
California Day-Fresh foods, irradiating orange
juice strips away 48% of its beta-carotene, 13%
of its Vitamin C, and 10% of its Vitamin A (www.citizen.org).
Many of the beneficial bonds involving simple
sugars and amino |
acids in produce
are broken down during the irradiation process. Irradiation
also extends the shelf life of produce allowing more
time for beneficial bonds to break down. The longer
a piece of produce is away from its vine or tree the
more the benefits of the produce are broken down,
no matter how good it looks. These factors render
current produce health benefits at a fraction of what
is historically understood and, more importantly,
a fraction of what the consumer expects or is aware.
No wonder the use of supplements is constantly on
the rise. Everyone has been told at least once by
their mothers to wash their apple or tomato to get
rid of the pesticides. With hydroponics, organics,
and Local Agriculture these modern realities are virtually
eliminated.
|
|
Another
option is simply being more creative with the
space we have available to us. Why not utilize
skyscrapers or underwater food production mechanisms
for cultivation. We could grow up instead of out
with skyscrapers and down instead of out with
underwater growth. The Earth's surface is over
70% water, so it seems the ability to utilize
this reality along with the three-dimensional
nature of the ocean to our advantage would eliminate
the land stress we are currently experiencing.
The possibilities and repercussions of this are
overwhelmingly positive and endless! |
Something can
also be said about the efficiency of large produce
corporations. It is estimated that 20% of all food
produced in America (about 137 million tons, worth
$31 billion) is wasted every year. Of that, about
60 million tons, worth $5 billion is simply left in
fields for lack of commercial value (USDA). Add to
that the increasingly high costs of packaging, storing,
preserving, handling, and transportation after it
leaves the field, not to mention the fossil fuels
burned in route, and the result is clear- we have
a very inefficient way of producing and supplying
food.
Hydroponics shows
the most potential in third world countries. There
is a growing understanding that on Earth we are trending
towards the scenario of "more people, less space".
For example, standard US agricultural practice today
requires at least 45,000 square feet of land to feed
a person on a high-meat diet, or about 10,000 for
a vegetarian. Developing nations aspiring to similar
diets have only about 9,000 square feet of land per
person available for cultivation, and that amount
will probably shrink with further urbanization, desertification,
erosion, soil salinization, and other stresses ("Natural
Capitalism", 210). Reference the chart below:

Hydroponic Food
Production, Howard M. Resh, Woodbridge Press, 2002
This chart elicits
the potential for increasing the efficiency of food
production via hydroponics. What is not quantified
in this chart is the potential for year-round production
via controlled environments. The increase in food
production can be magnified up to two-fold considering
the projected production mechanisms above can be experienced
in the winter months as well as the traditional growing
season with no interruptions. The concept of hydroponics
allows for the production of the same relative amount
of food in an average of as little as 1/5th the space.
Not only does
it increase the efficiency of food space, but it saves
water as well. Because hydroponics is recirculatory
by nature, up to 1/20th the amount of water is used
in hydroponics relative to field-based growing, respectively.
Around 30% of the water dumped on a field is actually
utilized by crops. The other 70% simply runs through
the root zone or is lost via erosion. Further, agriculture
is responsible for about twice as much of total US
water withdrawals as all buildings, industry, and
mining combined. It accounted for 81% of all 1995
consumptive use. 88% of the nations 1995 irrigation
water went to 17 western states, where the great majority
of all water districts were mining groundwater faster
than it is being recharged ("Natural Capitalism",
214). There is something further to say about the
use of water on specific crops. For example, 80% of
California's water goes to irrigation. A full 20%
of that water is used to grow alfalfa. Alfalfa is
not very water efficient in that the amount of water
used relative to the amount of usable foodstuff received
is very low, especially when it's grown in the deserts
of southern California. All of this alfalfa is cultivated
to feed to dairy cows (www.worldwatch.org, Brian Halweil,
June 07, 2002). To be clear, California is using 25%
of its TOTAL available water supply to produce a crop
they're feeding to cows! Individual situations such
as this if recognized and alleviated can have a dramatic
effect on the overall efficiency of our food production
mechanisms.
Couple these
statistics with the fact that demand for water is
increasing at a dramatic rate and there is cause for
creeping alarm. The supply of available water on Earth
is not much more now than it was 2,000 years ago.
(WATER PIC) Yet some 6 billion more people exist now
than at the dawn of civilization, and all of them
need water for agriculture, industry, and private
consumption and this number and demand is growing
daily. As world population tripled between 1900 and
1995, global water consumption rose sixfold- that
is, twice as fast as population! Demand for water
will continue to grow rapidly. Since 1970, global
demand for water has grown by 2.4% a year. Projections
indicate that water withdrawals will increase by 35%
between 1995 and 2020, reaching 5,060 billion cubic
meters. A primary pressure on water supplies is the
need for irrigation. Since most of the land suitable
for agriculture is already being cultivated, or even
decreasing, increases in food production must be achieved
by raising yields by, among other things, increasing
irrigation farming. In the first half of the twentieth
century, the acreage of land under irrigation doubled
worldwide. Between 1950 and 1990 this feat was repeated.
Water consumption in the agricultural sector has risen
by a factor of five since the fifties. Around half
the increase in food production achieved since the
end of World War II is due to the expansion of the
artificially irrigated proportion of the world's arable
land. Were it not for this spread of irrigated farming,
the world would already be faced with major food supply
problems. According to Mark Rosegrant of the International
Food Policy Research Institute (IFPRI- http://www.ifpri.org/),
global consumption of irrigation water will increase
by 4% by 2025, while that of non-irrigation water
is expected to rise by 62%, mostly due to increases
in industrial uses in developed countries. Should
this volume of water be unavailable, local food shortages
may be unavoidable ("Six Billion and Counting",
42-43).
It is interesting
the relative lack of perspective prevalent in literature
dealing with food production and in most of the world
organizations that deal with food security. In the
book "Six Billion and Counting", by Klaus
Leisinger, et al, it is noted that "although
suitable arable land is a prerequisite for any agricultural
operation, around 600 million hectares of potentially
arable land suffer from lack of water that inhibits
production." Why do we not begin to articulate
the potential positive repercussions of hydroponic
technology in the mainstream? They go on to say that
without sufficient water, the arsenal of technical
possibilities and hence the opportunities for higher
yields and multiple cropping cannot be exploited.
On average, irrigated farming is twice as productive
as rainfed agriculture and almost 40% of all foodstuffs
are grown on the irrigated 17% of the world's arable
land. Data from the UN Food and Agriculture Organization
(FAO- http://www.fao.org/)
demonstrates the effectiveness of controlled irrigation
for developing countries increasing the per hectare
yield of most food crops by 100 to 400%. These advances
in food production are positive steps, but doesn't
it make sense to further the progress we have already
made, particularly since the relative availability
of water despite these steps is being discussed? How
about doubling that 100-400% to 200-800% by creating
environments that allow year-round growing conditions?
Instead of concentrating on means of production that
seek to enhance a relatively unenhancable technique-
run to waste irrigated soil growth- why not focus
on means of food production that have our goals of
water conservation, maximum per square foot food production,
no pesticides, Food Security, and overall food nutritional
value in mind- recirculating controlled environment
hydropnic cultivation? Further, it seems logical that
with irrigated farming becoming more prevalent due
to its ability to increase yields, increase the demand
for labor and create jobs, and enhance the ability
of farmers to grow cash crops that recirculation,
or the conservation of water, should be the main focus.
Think about the
repercussions of retrofitting and augmenting our food
production systems with hydroponics. Food producers
could receive tax breaks or subsidies based on water
or energy conservation as opposed to the current subsidy
programs that wastes taxpayer money due to the lack
of control the farmer has over our market logistics
and weather. The total energy consumed by US agriculture
per year is equivalent to more than 30 billion gallons
of gasoline (714,285,000 barrels), and represents
more than 5 times the energy content of the food produced
("Solviva", 95)! Hydroponics can reduce
this energy imbalance via more efficient production
and cultivation techniques. Further, freshwater flows
from rivers are provided to agriculture under a program
of federal subsidies that go back to the 19th century.
California has built a vast agribusiness sector on
water so heavily subsidized that 57% of its agricultural
water grows four crops that produce only 17% of its
agricultural revenue, as attested to regarding alfalfa
above (Natural Capitalism, 215). From these examples
it is easy to see that we have a relative imbalance
in our water distribution and energy consumption in
regards to food production. This is not something
that only affects big corporations. It affects the
homeowner when we cannot water our lawns during water
sensitive periods or we cannot wash our car due to
drought or the price of our produce is higher than
we expect it to be. If the average individual could
make the connection between these unnecessary sacrifices
and food production do you think there would be more
of an impetus to create change? Exactly.
 |
The
other major advantage over our current food production
mechanism regarding hydroponics is the ability
to grow produce without the use of pesticides.
Currently, the utilization of pesticides is so
widespread due to the unhealthy nature of the
soil biology being cultivated. Using synthetic
fertilizers in a soil scenario weakens the surrounding
biology, in turn, warranting the use and overuse
of pesticides to compensate for plant weakness.
The best defense against pests and diseases is
a healthy plant. By |
separating plant
growth from natural systems it eliminates the stress
we put on them by way of our unnatural soil growing
techniques. Hydroponics allows us to directly feed
plants delivering exactly what they need for ideal
production as opposed to the plant being forced to
find what it wants in an uncalibrated environment.
As has been stated, plants eat the inorganic constituents
of "organic" materials anyway. It is also
relatively hard to utilize IPO's in an outdoor environment.
By enclosing the growing situation in greenhouses,
farmers can effectively keep tabs on development and
implement programs to combat potential problems. In
essence, farmers can create their own ecosystems so
as not to disrupt the ones around us.
|
The Food
Movement's sole focus is healthy food. Do we
really know what we eat? The answer is no. This
is not for lack of effort or interest or a scare
tactic, simply a repercussion of the nature
of our food production systems. There is no
"countertop analysis" available to
the consumer to test what may be in or on our
produce. We must rely on the integrity of the
production methods. This is the impetus behind
the "organic" labeling implemented
by the USDA. By maintaining guidelines for "organic"
food production the consumer can have a better
idea about how their food was produced and have
the piece of mind that they really know what
they're eating. The problem is that by mandating
"organic" food as the sole assurance
of Governmentally recognized healthy food, we
have effectively pigeonholed ourselves by excluding
equally, if not more, prolific and healthy means
of production.
Consumers
Union, a non-profit publisher of Consumer Reports,
did a study on pesticide residues across 8 fruits
and 12 vegetable crops grown "organic",
IPM/NDR, and conventionally. The study showed
that 73% of conventionally grown samples had
pesticide
|
|
residues. Residues
were found in 47% of the IPM/NDR produce, and 23% of
"organic" produce. Even more alarming is that
more than 90% of the samples of conventionally grown
apples, peaches, pears, strawberries and celery had
pesticide residues, and conventionally grown crops were
six times as likely as organic foods to contain multiple
sources of pesticide residues. This study shows that
"organic" produce is, by far, a safer product,
but it also suggests several opportunities for organic
growers and others to further reduce residue levels.
However, consumers who wish to minimize their dietary
pesticide exposure can do so with confidence by buying
"organically" grown foods. Most of the residues
in organic foods can readily be explained as the unavoidable
results of environmental contamination by past pesticide
use, or by "drift" (sprays blown in from adjacent
non-organic farms). Some foods sold as organic may also
be mislabeled, either because of fraud or because of
lapses in maintaining the identity of foods as they
move from the farm to the consumer. For a complete summary
of the study go here (http://www.consumersunion.org/food/organicsumm.htm)
|
|
Our
Federal programs are unimaginative and outdated.
The problem is that the Federal Government is
reactionary by nature. The USDA did not come up
with the idea of "organic" guidelines
the same way the FCC did not originate the idea
of the Internet. These progressions stem from
the human ingenuity that is the hope of the future
in terms of food production, water conservation,
Food Security, and overall human sustainability.
The Government is a conduit of the people, not
the other way around. The potential positive repercussions
of reprioritizing our food |
production via
the Food Movement cannot be quantified they are so
awesome. The reality is it comes down to us to demand
healthy food. Localizing food production will go a
long way to establish healthy avenues of competition
in the food production business. As we have it now,
large corporations are receiving the bulk of the subsidies,
in turn, being given a significant advantage over
the little guy. If the little guy can sufficiently
compete with the big corporations for market share
it will force the big guys to become even more reliable
in terms of food health and everybody wins.
The reality is
that unless we become more creative, flexible, and
willing to adopt more efficient and healthy means
of producing food our current systems of production
will not be able to sustain the intrinsic population
growth we are currently experiencing and expect to
experience over, at least, the next 40-50 years. The
idea is summed up nicely in an old Chinese proverb:
"Three thousand
years ago in the province of Chu lived a wise man
who knew the right answer to any question. This annoyed
two young men, who set out to play a trick on him
and prove that he did not know everything. One of
them took a small bird in his hands and hid it behind
his back. The other asked the old man: "What
is my friend holding behind his back?" The old
man answered: "A sweet little bird." Thereupon
the young man slyly asked his second question: "And,
honorable sage, is the bird alive or dead?" The
young men had agreed that if the old man answered
that the bird was dead they would release the bird
to prove he was wrong. If however, the old man replied
that the bird was alive, the young man would crush
the bird and show its corpse to the old man as proof
of his fallibility. "Well, old man, is the bird
alive or dead?" repeated the young man. The old
man smiled and said, "That lies entirely in your
own hands." ("Six Billion and Counting",
128)
The bottom line
is that we are caught in a mindset that has the reigns
over our innate intellect as a population. We cannot
allow ourselves to step outside the box regarding
food production in order to ensure its safety simply
because of the lack of general public recognition
and education on these concepts. It is a safe bet
to assume that if people really knew what they were
eating on a day-to-day basis regarding the nutritional
value and prevalence of pesticides in our food there
would be a public reaction demanding a reallocation
of our priorities in food production. Our priorities
and focus should not be method of growth, or profit,
or cost, or tradition, or soil integrity, but overall
availability and nutritional value of the final product.
