Context-Context-In the cold cruel world of life on planet earth:• Why would we (you, me, your parents, your friends, your state, your country

all of Society) want to “conserve” natural resources – if it’s not to sustain “useful” lands and natural systems for the future

(generations)?• If Sustainability is what we are aiming at, will our current

measures (way we live) “hit” the target? Given: – 1) Your (mine and our) attitudes, – 2) What you (me and us) have bought into, – 3) The way you do life, and/or – 4) The way we ALL DO LIFE.

• Since current definitions of sustainability segregate into four general, but related sectors; – 1) economics, – 2) social systems, – 3) agroecosystems (landscapes) and the – 4) environment,

Sustainability

• Definition: “the ability of a system to

continue in time”– It’s at the least a

presumption or presupposition about the future:

– involves at least:

• How well are you, me, WE measuring our own life outcomes relative to sustainability?

2- The Ecosystem2- The Ecosystem

3- Society

4- Economics

5. Can the natural environment be degraded

irrevocably?

4. The longer the long-term

consequences, the less likely

detected

3. Standard of living depends on production

2. Closed world system

B. Observations about sustainable thinking

What is an ecosystem?May be easier to understand an agroecosystem…

• A unit of management.= a spatial unit of habitat that a

producer identifies as a field, a block, a planting, a woods or a paddock; which he manages as a contiguous whole.

– Applies inputs to…as a unit.– Harvests from…as a unit.

“Hey, John! Spray ‘Dad’s back-ten’ before the wind gets up today! OK?”

“Yep, I’ll get ‘er done right now, Boss…”

Meso-area Biotic Exchange:• landscape interactions• recruitment & biotic flow

Everybody on the farm knows that this unit of landis ‘Dad’s back-ten’…it’s an agroecosytem.

What is an ecosystem?You can understand any unit of earth that you have

impact on as an ecosystem, your ecosystem…

• A unit of management.= a spatial unit of habitat that a

person identifies as a yard, a house, a block, a township a county or state or continent or earth; which he (you, me or we) manage or influence as a contiguous whole.

– Applies inputs to…as a unit.– Harvests from…as a unit.

“Hey, John! Mow the lawn! OK?”

“###%***##!!!, Ah, well, OK I’ll do it…(under his breath, I just got home and now this! Doesn’t he know that I’m not a kid anymore?” Jay Bruner Picture

Everybody in the house knows that this unit of landis ‘the back yard’…it’s an ecosystem—a unit of managed habitat.

Ecosystems:Abiotic and Biotic Integration

Abiotic Environment– Physical laws and structure:

• earth, soil, water, minerals, atmosphere…

– Cycles: H20, C, N, etc…– Chemical Interactions…

• metabolism & synthesis• degradation & mass action

– Energy flux: light, +/_ charge

• e.g. heat (long wave length light)

• e.g. electrical charges (chemical

bonds & enzymes)

• Biotic Systems– Species– Populations– Communities– Agro-Ecosystem– Ecozones– Hemispheres– Bioshpere– Earth– Solar System– Universe

1. Philosophy: stewardship of both natural and human resources

A. Definition of a sustainable land unit…"sustain," from the Latin sustinere (sus-, from

below and tenere, to hold), to keep in existence or maintain, implies long-term support or

permanence & YOU figure prominently in the equation…

You hold the key

to sustainability of the land,

its ecosystems and environment!

C. What Sustainable thinking seeks not to do

Fail to value all of life; including the soil,

microbes, plants,

animals, people, communities,

populations, cities, regions,

continents, the Earth!

One can not value something without

Some understanding of it!

Four disciplines: 1) environmental health,

2) functional ecology, 3) social and economic equity, & 4) economic profitability within the system’s

limits

2. Avoid long-term side effects

3. Use non-renewable resources slowly

4. Value the land and the people on it! That means farmers, they are your kids future!

5. Value Self-sufficiency… could you survive in a polluted world? A world without clean water? A world where you had to produce your own food and housing?

Farming looks mighty easy when your plow is a pencil, and you're a thousand miles from the corn field.

Dwight D. Eisenhower (1890-1969)US president 1953-1961

I believe that the great Creator has put ores and oil on this earth to give us a breathing spell. As we exhaust them, we must be prepared to fall back on our farms,

which is God’s true storehouse and can never be exhausted. We can learn to synthesize material for

every human need from things that grow.George Washington Carver (1860-1943)

Agricultural chemist, developer of crop-rotation and 325 uses for the peanut

Farmers are the only indispensable people on the face of the earth. Ambassador Li Zhaoxing (1940-present)

Ambassador Extraordinary and Plenipotentiary of the People's Republic of China to the United States
