Production SystemsProduction 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

Production SystemsProduction 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

• 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

How to assess these? They may not affect bottom line directly.

Cost of environmental Cost of environmental loadload
• 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?
