All Things Organic - Farms of the future need to be ecologically thrifty
By Ian Cushon

In the 1970s, rising grain prices encouraged mixed farmers to convert
livestock pasture to annual cropping. In the post-Crow era, grain production
became less economically viable as production inputs and transportation
costs increased while grain prices stagnated. Low margins pushed many
farms to become bigger to capture gains from economies of scale.
Recently, many farms returned to livestock production, converting cropland
back to forage and grass production. As well, there have been large investments
in intensive livestock production to take advantage of low-cost feed grain.
Prairie governments offer a variety of programs and subsidies to further
attract intensive hog production. The expansion of Alberta's large cattle
feeding and slaughter industry was largely a response to government-subsidized
feed grain. The cattle industry moved west as formerly mixed farms on
the eastern Prairies specialized more in grain. At one time almost all
prairie farms were mixed farms. While there are still mixed farms on the
eastern Prairies, there are fewer cattle finishing and slaughter facilities.
Intensive livestock and grain industries are economically viable because
of low-cost feed grain and energy. As non-renewable energy prices increase,
prairie agriculture will no doubt be transformed. Alternative energy sources
and technology such as genetic modification may send us down unpredictable
paths. I think many prairie farms of the future will be based more on
the principles of organic farming and have many similarities to the mixed
farms of the previous generation. This is not to suggest that they will
only be small certified organic farms adhering to strict rules and limited
to only using natural products. But the advantages of combining livestock
and crop production make mixed farming more energy and resource efficient.
North American agriculture has been fossil energy-intensive for only
a few generations. We pour non-renewable energy into crop production in
the form of fertilizers, chemical and mechanical inputs. Farms of the
future will likely be based more on renewable energy, such as methane,
bio-diesel, ethanol and nitrogen fixation. When fossil energy becomes
scarce and nitrogen fertilizers become too expensive, farmers will be
forced to replace nitrogen fertilizers with nitrogen-fixing crops. Farms
of the future will also be based more on knowledge-based management systems
that rely on natural processes.
Today's livestock system uses artificial fertilizers to grow high yielding
animal feeds. Rotational grazing increases productivity by taking advantage
of the natural cycling of nutrients between plants and animals. Farmers
can then rotate crops after the cattle and gain from fewer weeds, improved
soil quality and better soil fertility. Some economists suggest that the
market will regulate resource allocation and technology will solve all
our problems. But economicsdoes not adequately measure indirect costs
such as environmental damage.
Technology can certainly help us, but it has to be appropriate technology
that does minimal harm, is a good use of limited resources and is sustainable.
Regardless of how technologically advanced we think we are, we cannot
escape the reality that life on Earth is a complex web of biological interaction
and many of the earth's resources are limited. If natural systems stop
functioning, and for a dramatic obvious example let's say it stops raining
in Ethiopia or Alberta because of climate change, then food production
stops. While Albertans can afford to import food, the Ethiopians cannot.
It is ironic that many farmers who are completely dependent upon nature
and functioning natural systems are often critical of the concerns of
environmentalists. While farmers have every right to be concerned about
the impact of environmental policies on their ability to make a living,
it would seem that in the long run, ignoring environmental issues could
be bad forbusiness.
In The Future of Life, Harvard biologist Edward Wilson writes about
the loss of biodiversity and how humans use the world's natural resources
at an ever-growing rate. According to Wilson, the planet will run out
of resources to feed, clothe and house a growing population. In a dramatic
demonstration, Wilson writes about the ecological footprint humans leave
on the Earth. This is a method by which scientists calculate how much
of the Earth's resources are used to support a human life based on the
amount of land and resources that are required to support all aspects
of what that person needs. In the United States, it's estimated one person
uses 24 acres of land to provide their needs and wants. On average in
the developing world, humans use 2.5 acres of land to support themselves
- one tenth of the U.S. Wilson says that for the Earth's six billion people
to live at the same living standard and resource use rate as the U.S.,
we would need four more planets like Earth. So suggestions of using the
developed industrial world as the model for developing the underdeveloped
world seem impossible.
This inequity in sharing the world's resources also causes many conflicts.
As dire as his prediction sounds, Wilson is optimistic and says that there
are ways that we can change and that we need to begin now to plan and
implement a new world based on conservation, efficient resource use and
technological innovation.There will be no other way if we are to survive
on this planet.
