Farm as Ecosystem
Deep sustainability means transforming, not reforming,
agriculture

For too long, entomologists and pesticide salespeople have been called on
to solve insect pest problems; and soil chemists and fertilizer salespeople
have been called on to solve soil fertility problems. The occurrence of
pests and declining soil fertility, however, are not indicators of pesticide
and fertilizer deficiencies, but rather are symptoms of the way we design
and manage our agro-ecosystems. This design and management are what we must
examine if we are to make progress solving problems.
We tend to take symptom-focused, short-term, technology-intensive approaches
to solve problems. Furthermore, we tend to be enemy-oriented and to promote
deceptively simple solutions to eliminate enemies.
In contrast, the fully developed human being is probably someone who
sees no enemies and is willing to take mainly long-term, low-powered, bio-ecological,
indirect approaches. Problems solved this way require collaboration with
others and with the natural environment.
The path to achieving sustainable agriculture involves moving from an
acceptance of the status quo to a redesign of the whole agricultural system.
This path usually takes people through two intermediate viewpoints.
I call the efficiency and substitution models shallow sustainability,
and the redesign model deep sustainability. The jump from the substitution
model to the redesign model usually is the most difficult to make because
a redesigned agriculture is markedly different from the status quo; it requires
looking at agriculture in a whole new way.
Stuart Hill is an associate professor at McGill University and director
of Ecological Agriculture Projects. (See IC #34 for an article by Stuart
Hill on life in the soil.) This article is reprinted from The International
Alliance for Sustainable Agriculture's newsletter, Manna, published in Minneapolis,

Approaches: |
|
|
|
|
|
- Physico- chemical (soluble fertilizer, pesticides, biotech)
|
- Physical/ chemical/ biological
(slow release)
|
- Biological & natural materials
|
|
|
|
|
|
- Knowledge and skill intensive
|
- Narrow focus, farm as factory (linear design and management)
with products
|
|
|
- Broad focus: farm as ecosystem (integrated design &
management)
|
- Problems as enemies to eliminate & control directly
with products
|
- Efficient control (monitor pest, IPM)
|
|
- Prevention: selective and ecological controls (pests
are seen as indicators)
|
| Goals: |
Goal: |
Goal: |
Goal: |
- Maximize production (negelect maintenance)
- Create demand, manipulate wants
|
- Maintain production while improving maintenance
|
|
- Optimize production (emphasizes maintenance)
