2Descriptions Matter
- How we choose to make depictions of complex
systems affects what we can see of context and
consequence, and so affects outcomes - Complex systems are best conceptualized as being
arranged into nested levels of organization
3Elements of An Ecosystem Approach
- Processes
- Boundaries
- Scales
- Purpose
- Perspective
4Properties of An Ecosystem Approach
- Nested Assembly
- Scale-hierarchic Levels of Organization
- Rate-dependant Boundaries
- Purposive Descriptions
- Scale-dependent Structuring
- Functional Associations
5An ecosystem approach based on nested
scale-hierarchic process-function ecology
offers the most effective basis for making
robust descriptions under complexity

12Toxic Pollution and Life Expectancy
- In a memo dated December 12, 1991, Lawrence H.
Summers, then Chief Economist at the World Bank,
is said to have suggested that toxic industries
be relocated to nations with the lowest life
expectancies and the lowest wages - Weve done just that!
13Local Impacts of Globalization
- The globalization of production means a huge
increase in international goods movement - Diesel-powered ships, trucks and trains are what
we use to move these goods - Diesel exhaust is highly toxic
14The Hidden Costs of American Consumerism
- Communities residing and working around goods
movement nodes and facilities pay a high price in
health impacts too

30Recommended Buffer Zones for New Construction
- California Air Resources Board recommends a 300
to 1,700 foot downwind buffer between freeways
and human activity - Sensitive Receptors should be sited at least
500 feet away when downwind from freeways - No recommendations for existing structures

31Conventional Depictions Are Confrontational
- Community groups and the Port Administration
depict one another in oppositional roles, with
State and Regional governmental agencies playing
mediative roles - Non-profit groups tend to align themselves in
activist roles alongside communities and against
the Ports
32Consequences of Confrontational Depictions
- Given the oppositional characterization of roles,
the debate is primarily limited to issues of
physical growth in port activity - Community groups seek to limit growth, Port
authorities seek to expand growth, and that sets
the modalities for the discourse
33Depiction as Nested Levels of Organization
- Allows all relevant processes and functions to be
kept in play, with associations and relationships
shown in their actual configurations and
strengths - Allows effects to be traced across levels of
organization, with adjustments for benefits and
disbenefits at different levels to be affected
more directly

35Benefits and Disbenefits
- Benefits are clustered primarily at the
sub-system and supra-system levels of
organization - Disbenefits are concentrated primarily at the
system level of organization

37Redistribution of Benefits
- Some small portion of the benefits accruing to
the manufacturing, shipping, logistics and
consumer markets should be redirected to
remediate the adverse impacts at the neighborhood
level of organization
38Integrative Ecosystem Approach
- Identification of properties most at risk
- Design of buffer zones, using urban forestry and
landscape elements - Redesign of neighborhoods using transit-oriented
smart growth sorts of urban design strategies, to
accommodate potentially displaced families within
their current neighborhoods, where possible - Accelerated turnover of truck and rail fleets
toward low-sulfur diesel and alternative fuels
