1. The document discusses sustainable agriculture and defines it as a farming system that mimics natural ecosystems by being profitable, environmentally friendly, and supporting communities.
2. Key aspects of sustainable agriculture include diversification of crops and livestock, applying organic matter to soils, using cover crops and crop rotations, and direct marketing to consumers.
3. The goals of sustainable agriculture are to provide secure livelihoods for farmers and rural communities, ensure access to healthy food for all, and preserve environmental resources like soil and water quality.
4. 1.Available natural resource base, including water, land,
biodiversity ,grazing areas and forest; climate, of which
altitude is one important determinant; landscape,
including slope; farm size, tenure and organization; and
dominant pattern of farm activities and household
livelihoods, including field crops, livestock, trees,
aquaculture, hunting and gathering, processing and off-
farm activities.
2.Taking into account the main technologies used,
which determine the intensity of production and
integration of crops, livestock and other activities.

5. The word "sustain," from the Latin sustinere
(sus-, from below and tenere, to hold), to keep
in existence or maintain, implies long-term
support or permanence.
6. TheTechnical Advisory Committee of
Consultive Group of International
Agriculture Research ( CGIAR) define
Sustainable Agriculture “ Successful
management of resources for agriculture to
satisfy the changing humans needs while
maintaining or enhancing the quality of the
environment and conserving natural
resources”.

7. A farm system that mimics as closely as
possible the complexity of a healthy and
natural ecosystem.
Goals include:
▪ Providing a more profitable farm income.
Promoting environmental stewardship.
Promoting stable, prosperous farm
families and communities.
8. Reduces inputs.
Uses ecological pest and weed management
strategies.
Cycles nutrients back into the soil for fertility
and health.
Strengthens rural and urban communities.
Produces viable farm income.
Promotes healthy family and social values.
Brings the consumer back into agriculture.
9. “…an integrated system of plant and animal
production practices…that will
▪ satisfy human food and fiber needs
▪ enhance environmental quality
▪ make the most efficient use of
nonrenewable resources
▪ sustain economic viability
▪ enhance quality of life.”

10. Intercropping, diversity
and cover cropping
Crop rotation
Farmscaping
Use of
resistant
varieties
11. Residue cover protects the soil from wind and
water erosion.
Allows for greater moisture retention in rainfed
systems.
These systems build soil organic matter over a
period of years, and reach a higher “steady
state” level than tilled systems in the same
environment.
12. The use of fresh or undecomposed manure in
agricultural systems is of great benefit to the
farm.
There are variations in nutrient profiles of
animal manures.
If using raw manure, cannot apply to fields
for
organic certification less than 120 days before
harvest.
13. Use of compost in crop production and grass
farming is beneficial to build soil organic matter,
add nutrients to the soil and retain water.
Nutrient contribution of manure-based
compost is balanced between N-P-K. Have a
compost nutrient assessment done.
How much compost to apply and timing is
different on each farm.
Ease and economics of use, local availability
and costs as well as variability of quality.
14. Cover crops improve the soil’s physical
properties with carbon and nitrogen cycling.
Some cover crops actually suppress certain
parasitic nematodes and soil borne diseases, i.e.
rye, triticale, mustards.
Cover crops have superb weed suppressing
effects by competing with weeds for light and
smothering unwanted plants or through
allelopathy.
Reduce erosion and attract beneficial bugs.

20. Typical definition looks at physical surrounding (land,
air, water, plants, living /non living organisms etc).
Contemporary definition, include social, economical and
political components of environment.
General definition, include institutional frame work,
capacity, investment climate, geopolitical constraints
etc are non physical elements of the environment in
which every ecosystem has to operate and survive

effect

6. Chemical pollution

22. Sustainable agriculture can be viewed as management
of a production system where there is a multitude of
complex interactions occurring between soil, water,
plants, animals, climate and people.
The GOAL is to integrate all these components into a
solid production system that benefits all participants.
Farms stay environmentally sustainable by mimicking
natural processes and ecosystem function.
Diversifying our farms with various enterprises, both
animals and crops, we manage risks a whole lot bet
23. Energy flow is the pathway of sunlight through a
biological system.
In relation to the farm, energy capture is
enhanced by
maximizing the leaf area available for
photsynthesis
and by cycling the stored energy through the
food
chain.
We make money in farming by capturing
sunlight –
in essence, we are farming the sun (and the soil).
24. An effective water cycle includes: no soil
erosion, fast water entry into the soil and the
soil’s ability to store water.
Management decisions on the farm that add to
ground cover and soil organic matter only
enhance the natural water cycle.
Effective water use on the farm results in low surface
runoff, low soil surface evaporation, low drought
incidence, low flood incidence, high transpiration by
plants and high seepage of water to underground
reservoirs (Savory and Butterfield, 1999).
25.
26. In nature, minerals needed for plant and animal
growth are continuously being recycled
through the ecosystem.
An effective mineral cycle is one where there
is a movement of nutrients from the soil to
crops and animals and then back to the soil,
basically a circle of nutrient renewal.
Ways to enhance this cycle on the farm
include: on-farm feeding of livestock, careful
management of manure and crop residues, and
practices that prevent erosion
27.
28. A farm will be dynamic and healthy if it has a
high diversity of plants and animals (above
ground and below).

DIVERSITY =

32. Goal is to find and adopt "integrated and resource-
efficient
crop and livestock systems that maintain productivity,
that are
profitable, and that protect the environment and the
personal
health of farmers and their families," as well as
"overcoming
the barriers to adoption of more sustainable
agricultural
systems so these systems can serve as a foundation
upon
which rural American communities will be revitalized
35. Economic concentration of agribusiness gives
farmers little power or control over
production,
marketing and distribution.
Loss of farms --155,000 farms were lost
from
1987 to 1997 and 30 million acres have been
lost to development.
