High yield agriculture has enabled more people to live without
hunger while using less land.
High yield agriculture, according to its critics, is also
responsible for everything from Amazon deforestation, to
increased global warming, to an untenable breakdown of societal
relationships.The need for
a realistic answer is obvious—one in six people around the world
go hungry, more than 1 billion of them, according to the World
Food Programme.
“The world faces the largest
humanitarian food challenge in its history,” said Alex Avery,
Director of Research and Education with the Center for Global
Food Issues at Hudson Institute. At the 2008 Beef Quality Summit
he explained, “Over the next 40 years world food demand will at
least double, and we have little new farm lands with which to
meet that demand. We really have only more productive farming
methods to use on our existing farm lands.”
Technological Success
To this point in history, modern high-yield agricultural
production has offered an unparalleled example of making more
from less.
According to statistics from the
USDA Economic Research Service, between 1950 and 2000: average
corn yield grew from 39 bushels to 153 bushels per acre; the
average amount of milk produced per cow increased from 5,314
lbs. to 18,201 lbs; each farmer in 2000 produced on average 12
times as much farm output per hour worked as a farmer did in
1950. Development of new technology was a primary factor in this
progress.
“It took some 10,000 years to
expand food production to the current level of about 5 billion
gross tons per year. By 2025, we will have to nearly double this
amount again. This cannot be done unless farmers across the
world have access to current high-yielding crop-production
methods as well as new biotechnological breakthroughs that can
increase the yields, dependability, and nutritional quality of
our basic food crops,” explained Nobel Prize winner, Norman
Borlaug in a 2001 speech at Tuskegee University.
During that speech, Borlaug, who
passed away last year at age 95—he was still an active professor
emeritus at Texas A&M University—credited Fritz Haber and Carl
Bosch for what many consider the primary enabler of such
dramatic increases in crop yields. They demonstrated and
developed the industrial synthesis of nitrogen from its
elements.
“It is only since WWII that fertilizer use, and especially the
application of low-cost nitrogen derived from synthetic ammonia,
has become an indispensable component of modern agricultural
production,” Borlaug explained.
Buy Local or Die
As with many activist debates, the one surrounding modern
high-yield sustainable agriculture often gets wrapped up with
other ones.
For instance, critics of high
yield agriculture are often the same ones decrying corporate
farming and globalization. As for the former, the implication is
that large is equivalent to corporate and that a corporate
business structure disallows family farming.
The opposite, of course is true. There’s been some consolidation
of farms, with the total land in farms declining from 948.4
million acres in 1999 to 919.8 million acres today, according to
Farms, Land in Farms and Livestock Operations 2009 Summary from
the National Agricultural Statistics Service. Yet, by the USDA
definition of a farm—one returning $1,000 or more in annual
gross revenue—there are actually more farms today than there
were a decade ago—2.187 million in 1999; 2.200 million in 2009.
Incidentally, the number of
operations with beef cattle declined 4,000 last year to 753,000.
In terms of business structure, according to the U.S.
Agriculture Census, about 97% of these farms are owned and run
by private individuals, families and partnerships.
As for local versus global the
fact is that the United States exists in a global economy today,
not one where the U.S. dictates the cost of goods around the
world like it did previously. Now, emerging economies like
China’s mean the U.S. must compete for commodities it used to
set the price for.
The popular argument is that if
the agriculture in one area was also marketed in that same
area—buy local—everyone would surely be better off. Why import
what you can grow right here at home?
Ignore the fact that, according
to the USDA Economic Research Service, non-metro areas account
for 17% of the U.S. population but extend across 80% percent of
the land where most agricultural production takes place. Forget
the standard of living possible because U.S. citizens spend less
than 10% of their disposable income for food.
Besides the extraordinary way
U.S. producers have harnessed technology to produce more with
less, eating well on such a small portion of disposable income
stems from the comparative advantages associated with particular
regions and nations. If regions of this nation or the world grew
crops other than those most suited to their production
potential, agricultural production would decline while consumer
prices increased. That would seem to run counter to feeding the
hungry and increasing the standard of living of more of the
world’s citizens.
In an insightful policy primer
from the Mercatus Center at George Mason University, authors
Pierre Desrochers, Associate Professor of Geography at the
University of Toronto and Hiroko Shimizu, an Economic Consultant
provide a logical discussion of the argument. They say it
revolves around a concept called food miles—how far food travels
from origin to consumption—and the notion that food grown and
marketed locally corrects the ills some folks associate with
commercial agriculture.
“Organic, fair trade, slow, and local describe food activist
movements whose stated goals are to allow consumers to express
their preferences or opinions against the offerings of large
multinational corporations and conventional retailers,” say
Desrochers and Shimizu. They explain the alleged benefits of
local subsistence agriculture versus non-local commercial
agriculture usually revolve around these arguments:
“Environmental—Because locally grown food items travel shorter
distances than those produced in more remote locations, they are
said to generate less CO2 and other greenhouse gas emissions.
More diversified local food production systems are also viewed
as more environmentally sustainable than large, export-oriented
systems where only one variety of crops is planted.
Social—The globalization of the
food-supply chain is said to have eroded the community ties that
once existed between geographically proximate food producers and
consumers. Rebuilding these ties would generate significant
social benefits.
Health—There is much concern over
the safety and quality of conventionally produced food grown or
raised in countries with lower health, safety, and environmental
standards. Food produced in closer proximity to consumers in
more developed economies is also often viewed as fresher and
therefore more nutritious and better tasting.
Economic—Locally produced food
items improve the economic circumstances of (mostly small-scale)
farmers who otherwise struggle in the face of international
competition, along with the fortunes of smaller stores who
cannot access the international food market as easily as large
food retail chains, thereby improving the economic viability of
rural communities and independent retailers in advanced
economies.”
“While intriguing, the food-miles perspective fails to question
the rationale behind the development of our modern agricultural
production and distribution systems,” say Desrochers and
Shimizu. “In other words, why is it that past consumers in
advanced economies unambiguously rejected not only the rural
lifestyle, by moving en masse out of farming-related activities,
but also increasingly favored food items produced in ever more
remote locations?”
Reasonable Alternatives
Computer wunderkind, Bill Gates, of all people, brought a voice
of reason to the sustainability debate last fall when he decried
both those in favor of increased agriculture production at all
costs, and those opposed to using technology to increase
production.
Speaking at the World Food Prize
in Des Moines, IA last October, Gates cautioned that progress
toward alleviating global hunger is, “endangered by an
ideological wedge that threatens to split the movement in two.”
On one side, he said, there are groups that support
technological solutions to increase agricultural productivity
without proper regard to environmental and sustainability
concerns. On the other, there are those who react negatively to
any emphasis on productivity.
“It’s a false choice, and it’s
dangerous for the field,” Gates said. “It blocks important
advances. It breeds hostility among people who need to work
together. And it makes it hard to launch a comprehensive program
to help poor farmers. The fact is, we need both productivity and
sustainability—and there is no reason we can’t have both.”
Gates—through his Bill and
Melinda Gates Foundation—has donated $1.4 billion so far to
global agricultural development efforts.
At the annual World Food Prize
event—since 1986 honoring individuals for vital contributions to
improving the quality, quantity or availability of food
throughout the world—Gates urged governments, donors,
researchers, farmer groups, environmentalists, and others to set
aside old divisions and join forces to help millions of the
world’s poorest farming families boost their yields and incomes
so they can lift themselves out of hunger and poverty. Gates
said the effort must be guided by the farmers themselves,
adapted to local circumstances, and sustainable for the economy
and the environment.
“The appeal of the food-mile
perspective, with its promise to reconnect people with food,
neighboring producers, and seasonality while delivering
environmental, economic, heath, and social benefits, is
superficially obvious,” say Desrochers and Shimizu.
“Unfortunately, these issues are generally discussed in an
emotional context, based on activists’ distrust of large
corporations and romanticization of subsistence agriculture
rather than on scientific or reliable information based in
fact…the benefits claimed by food-miles proponents have little
basis in fact while providing a new set of rhetorical tools to
bolster protectionist interests that are fundamentally
detrimental to most of humankind.
“Subsistence agriculture, which
is ultimately what the food-miles concept boils down to, is of
course feasible, but it implies significant trade-offs that may
not be readily apparent to most people who fail to understand
that our modern food supply chain is a demonstrably superior
alternative that has evolved through constant competition and
ever more rigorous management efficiency.”
