Environmental Opportunities for Animal Agriculture: Extensions Critical Role Dave Beede
3
Two Questions ? What are current and future environmental opportunities for animal agriculture? What should be and/or are Extensions roles? http://www.mdr.msu.edu

Overview Working Lunch Two Questions (handout) Systems Thinking in farms? Criteria for Evaluation of Agriculture Systems Potential Climate Revenue Centers, Market Opportunities Applied Research? Extensions Current and Future Role

Dairy Farm (System)

Production Systems Industry: –Straight line production process Raw materials product replacement over time Highly efficient operations Little waste material resulting from process Agriculture: –Circular flow of nutrients (cycle) –Products and wastes leave cycle May re-enter cycle –Human/societal waste, food residues, etc. –Raindrops collect gases and particulates from air Sustainable (systemic), but not perpetual Industry vs. Agriculture Hoshiba, S. 2002. In: Greenhouse Gases and Animal Agriculture
11
Production Systems Industrial Agriculture Industrial Agriculture –Straight line production Import of some raw materials (feed, fertilizer, bedding) Raw materials product exported Quite inefficient (25 to 35% for animal products) Large amounts of waste; e.g., dairy……. (240 lb intake – 90 lb milk) = 150 lb out as manure Accumulation of nutrients (risk)? Not sustainableNot sustainable - Paradigm of industry is not directly transferable to agriculture Industry vs. Agriculture Hoshiba, S. 2002. In: Greenhouse Gases and Animal Agriculture

The farm as a sub-system The farm (F-x) as a sub-system F-4 F-1 F-6 F-8 F-7 F-3 F-5 F-9…. F-2 Environment Environment U.S. farms Outflows Inflows
18
Systems are: Artificial – imposed by humans Hierarchical structure –Systems of lower levels are sub-systems of higher levels –Higher systems create new entities e.g., trade organizations, cooperatives, markets –Systems are embedded in an environment Material and energy flows amongst each other Interact with each other The farm as a sub-system
19
If the System is all livestock and crop farms, where does the Phosphorus in corn distillers grains come from?! F-4 F-1 F-6 F-8 F-7 F-3 F-5 F-9… F-2 Specific example of systems-approach
20
Answer: Origin of P accumulating in U.S.-Agricultural System
21
Net phosphorus flow NotNot added to the system by corn distillers grains –Just not re-distributed evenly Inflow of P to the system –Mined inorganic P (feed, fertilizer) –May not (does not!) counterbalance P outflow U.S.-agricultural system

23
Criteria of evaluation? 1. Profitability, economic efficiency Bottom line for farms (sub-systems) 2. Input of fossil fuel (energy) 3. Environmental load Ecological sustainability or stewardship 4. Animal welfare 5. Human welfare (social benefit) Kawakami et al., 2000. Agricultural production systems
24
Criteria of evaluation? 1.Profitability, economic efficiency –Bottom line for farms (sub-systems) 2.Input of fossil fuel (energy) –Net addition of CO 2 3.Environmental load (P, C, N; chem. species?) 4.Animal welfare 5.Human welfare ( social benefit) Agricultural production systems Kawakami et al., 2000. How to assess these? They may not affect bottom line directly.
25
Cost of environmental load Time lag Partially exported into environment (the community) –Who is responsible for cost of environmental clean up? e.g., from EtOH production? –Up-front cost (prevention) cheaper? –How is farmer paid for compliance? –Cheap food policy vs. environmental protection?? –Climate/ environmental market potential for farmers?

System evolves over time System embedded in environment Forces from environment –System affects environment –N-S-P-E-C-T perspectives Actions within the system Strategy: Actively affect environmentStrategy: Actively affect environment (vs. passively being affected)
29
Predicting the Future Anticipate changes and developments in the system and its environment –Goal: Prepare farm (sub-system) for future success CHALLENGE: Try to avoid getting the future wrong vs. the impossible task of getting it absolutely right. R. Bawden: Scenario Planning as an Experiential Exercise in Social, Reflexive and Transformational Learning
30
Prediction is very difficult, especially about the future – Niels Bohr 1.Heavier-than-air machines are impossible. – Lord Kelvin, 1895, British mathematician, physicist, and President of the Royal Society 2.I think that there is a world market for about 5 computers. – Thomas Watson, 1943, Chairman of IBM 3.We dont like their sound. Groups with guitars are on their way out. – Decca Recording executive, 1962, on turning down the Beatles for a recording contract Cerf and Navasky, 1984. The Experts Speak. Pantheon Books. Predicting the future??
31
Factors of future scenarios Predicting the future using N-S-P-E-C-T Impact Uncertainty Low High Critical cohort of influences R. Bawden: Scenario Planning as an Experiential Exercise in Social, Reflexive and Transformational Learning

Examples for dairy farming Predicting the future using N-S-P-E-C-T DomainImpactUncertainty Emission regulations Land prices (biofuels influence) Animal welfare (confinement) Availability of feeds Nutrient management Use of hormones Antibiotics Climate profit centers, exchanges
33
Role of THE Extension Educator? 1.Recognizes changes progressive 2.Imagine into existence future scenarios potential climate/environmental profit centers 3.Anticipates ( N-S-P-E-C-T ): social benefits, potential climate/environmental profit centers, exchanges, etc., etc.? ~ Initiates proactive change 4.Anticipates regulations ~ Initiates pro-active change ~ Mediator between farmers & scientific community
