1. Agriculture - review on impact
nexus of water, soil and energy
major portion of water budget
substanstial (but not majority) portion of global energy budget
amount of land in production

of which 40% is seriously degraded (wiki reading on Agriculture)
1/3 of population works in food production (ibid)
less than 5% of global aggregate GDPs (ibid)

2. Principles of Sustainability
definitions - to be negotiated
"sustainable development"
sustainable resource - from Norton
a. The systems view: a necessary condition
b. The philosophy of sustainability
active debate between different camps
"Grand Simplification" "since we do not know what people in the future will need - and since resources are substitutable for each other - the only thing we can do is to meaures and compare welfare across time." - i.e. increase capital of any forms
vs.
Norton:
- intergenerational responsibility
- choice and freedom to choose
- the culture will instill meaning - "To project those meanings into the future requires a commitment and also countless day-today acts that express and perpetuated those meanings. It is in this profound sense that sustainable living cannot be relegated to a matter of economic accounting; it is inevitably a process by which community values are articulated through the choice of what stuff to save."
c. The "machine" metaphor
using words like "dashboards", "levers of change", 2D Venn diagrams
Controlling complex systems
large amount of energy in overhead
d. The "organic" metaphor
using words like "grow", "coevolve"
notes - Norgaard
e. The very difficult path
What if sustainability is an emergent phenomenon?
- can't be taken apart -
- examples:
- ants, termites, socially constructed organizations
- individuals with simple rules that work together to form a larger structure
It could be a very difficult path to being truly sustainable.
need all the pieces and processes to be in place
metaphor of trying to tie up three rafts in the rapids (have to grab it at just the right time)
f. Visions for the future
Books:
- Odum, H. T. a. E. C. O. (2001). A prosperous way down: Principles and Policies. Boulder, University Press of Colorado.- notes
- McKibben, B. (2003). Enough: Staying human in an engineered age. New York, Henry Holt and Company.

3. Innovation
improvements in products or processes
In normal times, copying successful approaches or slight modifications is often the best strategy.
In difficult times, innovation is much more important.
- the rare solutionis more valuable
- need to promote diversity and risk taking
diffusion of innovation - link
- traditionally
- word of mouth
- individual training
- more recently
- embed the information in the device or provide training with the process
- moves through the landscape
Innovation requires:
- protection from being overwhelmed by the mainstream or normal methods
- including regulations such as BMP
- information rich environment

4. Community support for agriculture
organic farm going out of business
CSA solves a problem of labor and capital
Real Dirt on Farmer John - at library
52:48 to 64:??

5. Some aspects of the Portland Experiment with Food
Summary:
- many new trials are going on by small groups
- general public is also very active
- sets of regulations that are favorable
- economic situation seems favorable
- may have the pieces to form an emergent transition to sustainability

5a. List of activities
Local food production
CSA
Farmers markets all through out Portland area
using the commons to grow food
Philadephia Orchard Project and the map of edibles
Portland Urban Edibles and the discussion of ethics
Seattle fruit tree harvest
Chickens? Portland has highest per capita chicken population
article
urban chickens blog
Tour de Coop - maybe get a job here?
Urban Growth Boundary keeps farms nearby - map
Walking sheds
Walk There!
20 minute neighborhood (or less)
Economics
buying local food has the highest multiplier because all that money stays local
powerpoint Local Multiplier
local stores provide gathering places to build social capital

5b. Positive indirect interactions
feedbacks and other activities that might help promote these actions
biking - shorter trips with lower cargo (although see -->)
parks and usable greenspaces that may be used for growing food
air and water quality initiatives that make growing food locally safe
|
|
5c. Problems that might interfere
potential toxics in the environment that gets transmitted to food
cost of local food may be higher
local income tax base may suffer if people earn less but switch to the barter economy for food, etc. (but Oregon doesn't have sales tax)
|
|
5d. Environmental Thinking
allowing urban people to get their food from the environment directly
such as picking fruit or growing chickens
rethink ideas about:
public / private land
wild / domesticated
human (urban) / nature (out there somewhere)
