WHAT IS SUSTAINABLE AGRICULTURE
The
term sustainable agriculture means “an integrated system of plant and
animal
production practices having a site-specific application that will, over the
long term:
·
satisfy human food and fiber needs
·
enhance environmental quality and the natural resource base
upon which the agricultural economy depends
·
make the most efficient use of non-renewable resources and
on-farm resources and integrate, where appropriate, natural biological cycles
and controls
·
sustain the economic viability of farm operations
·
enhance the quality of life for farmers and society as a
whole.
GOALS OF SUSTAINABLE AGRICULTURE
·
The goal of sustainable agriculture is to minimize adverse
impacts to the immediate and off-farm environments while providing a sustained
level of production and profit.
·
Inherent to this goal is the understanding that
sustainability must be extended not only globally, but indefinitely in time,
and to all living organisms including humans.
·
Simply stated, sustainable agriculture refers to the ability
of a farm to produce food indefinitely, without causing irreversible damage to
ecosystem health.
TODAY’S METHODS
Today,
sustainable farming practices commonly include:
p crop rotations that
mitigate weeds, disease, insect and other pest problems; provide alternative
sources of soil nitrogen; reduce soil erosion; and reduce risk of water
contamination by agricultural chemicals.
p pest control strategies
that are not harmful to natural systems or people, which include techniques
that reduce the need for pesticides by practices such as scouting, use of
resistant cultivars, timing of planting, and biological pest controls.
p increased
mechanical/biological weed control.
p soil and water conservation
practices.
p strategic use of animal
and green manures.
p use of natural or
synthetic inputs in a way that poses no
significant hazard to man, animals,
or the environment.
A. Crop rotation keeps the soil healthy.
B. Mixed farms allows the uses of
livestock manure.
C. Conserving natural areas protects our
environment.
D. Small changes in practices can help,
rather than harm, the environment.
E. Grass-fed livestock control weeds
without chemicals or mowing.
F. Science can determine the right
amount of fertilizers and pesticides.
G. Farming removes nutrients and
fertilizers or manures replace them.
H. Farming multiple crops allows
farmers to reduce their financial risks by having multiple products to sell.
Organic vs Sustainable Farming
p Organic farming excludes
the use of synthetic inputs, such as synthetic fertilizers, pesticides,
herbicides, and GMOs, whereas sustainable agriculture does not.
p Sustainability aims to
balance between what is taken out of the soil with what is returned to it,
without relying on outside inputs. This is not necessarily a concern of organic
farming.
p Organic farms constitute
only a small percent of farms with a minor impact on the environment. Sustainable
agriculture aims to make positive changes on all farms.
p In the future, large
organic farms that rely on machinery and automation, and purchased inputs, will
have similar sustainability issues that large conventional farms do today.
Advantages of Sustainable Agriculture
Sustainable
agriculture is an agriculture production and distribution system that
•
Achieves the integration of natural biological cycles and controls.
•
Protects and renews soil fretility and the natural resource base.
•
Optimizes the management and use of farm resources.
•
Reduces the use of non-renewable resources and purchased production inputs.
•
Provides an adequate and dependable form of income.
•
Promotes opportunity in family farming and farm communities.
