5Main problems with current economic theory
- Externalities
- - costs not borne by those who create them
Badly defined property rights - environmental
goods perceived as commons
The environment is not subject of rights - the
environments interests are not legally
represented in the economic system
6Internalization
- London Congestion Charge
- 5 daily for driving or parking a vehicle on
public roads within the congestion charging zone
between 0700 and 1830, Mon to Fri - Goals
- reduce congestion
- improve bus services
- improve journey reliability for car users
- make the distribution of goods and services more
reliable, sustainable and efficient
7Changes in traffic entering and leaving the
charging zone during charging hours - 2003 vs.
2002

8Commodity system challenges
- What are commodities?
- What forces drive the commodity markets?
- What are the challenges of the CS?
- How to neutralise them?
Source Sustainability Institute 2003.
9What are commodities?
- Raw material or only little processed item
- Traded product
- Uniform characteristics everywhere the same
- Standardization and substitutability
- Choice based on price since all are the same
10Commodity systems
- Mono-culture Few similar, specialized
large-scale producers sell internationally - Huge production increases Large price
decreases

163 commodity systems traps !
Trap Easy to fall in, Hard to get out
17Evidence of trap 1 resource depletion
18Resource depletion trap
Regeneration rate
Harvest
Rate
Resource level
-
19Often when supply seems plentiful
Over-harvest
20Resource depletion trap WHY?
- Harvest capacity overgrows
- passes sustainable yield ? overshoot
- Market signals of scarcity (prices are said to
reflect scarcity, arent they?) - too weak, too delayed
- Endgame tactics
- final desperate efficiency boosts ? harvest
increase as resource disappears
21-
- Socialism collapsed because it did not allow
prices to tell the economic truth. - Capitalism may collapse because it does not
allow prices to tell the ecological truth.
Source Dahle, 2001.
22Resource depletion trap HOW TO ESCAPE?
- Better information feedbacks
- Link health of resource with change (increase or
decrease) in harvest capacity - Research to accurately know rates of harvest and
resource regeneration - Better control of capacity
- Rates of harvest and death never exceed
regeneration rate
23Environmental pollution trap
-
Waste level
-
Waste generation
Purification rate
24All production is joint production !
Implied by the First and the Second Laws of
thermodynamics
- permits to depict externalities related to
production - solid foundation for the precautionary principle
Source Faber et al. 1998.
25Community decline trap
Producer-buyer power differential
-
Community well-being
Producer-landlord power differential
-
-
Producers income
Number of producers

Consolidation rate

26Where do the problems come from?
- Strength tight information focus
- Narrow focus down to volume and cost makes system
lean and efficient - Weakness ignorant of long term trends
- Lack of feedback blinds us to signs of pollution,
resource depletion, community decline - Similar situation in most types of markets
27How to escape the commodity traps?
- Market products outside the system
- High quality products recognized as unique by
where and how produced - Restructure the system
- Change rules, incentives and penalties to balance
productive capacity with environmental and social
goals
28How to escape? More detailed strategies
- Collective agreement to limit harvest intensity
- Producers agree on a new set of rules ?
individual rational choices add up to sustainable
harvest - Agreements to limit price supports and supply
- Producers give up the right to produce any amount
in return for guaranteed minimum prices - Certification programs
- Bring environmental and social goals into the
system
29Certification of organic farming
30Certification ? fair trade coffee
- price covers the cost of production
- social premium for development purposes
- partial payment in advance to avoid small
producer organizations falling into debt - contracts that allow long term production
planning and sustainable production practices - decent wages, good housing, minimum health and
safety standards, right to unionize, no child or
forced labor - minimum environmental requirements
31Success ? surviving global price gyrations
Fair trade producers never fall below critical
minimum price
Price drops force many other producers
out. Result starvation in Central America
32But... certification is only a partial answer
- Depends on substantial increase in demand
- Still vulnerable to certain traps such as
over-production - If some use extra income to expand production
capacity - If environmental practices are certified without
focusing on balancing production with demand ?
fall into trap of overproduction and declining
incomes
33A good certification programme
- A step to bring multiple goals to commodity
system - Must work with other strategies as part of system
re-design - Changes range of allowed practices, but not
guaranteed block of production growth drivers - Must build on all 3 goals (soc econ ecol)
- Voluntary consumer behavior is the power behind
it and also its limitation
34And finally... we can rely on government
- Shape incentives and rules
- legislation
- directives, rules and sponsoring and leading
debates that establish agreements - New institutional structures
- taxes, fines, and legal sanctions
- direct payments
- bringing different stakeholders into decision
process
35(New) institutional economics
- Aware of interdependencies between economy and
nature - Focused on transaction, empowerment and
government failures and means to correct them - Investigates roles of insitutions (as principal
agents of change)
36Less pollution and more funds for education
Iowa tax on fertilizer use Funds used to educate
farmers in more efficient methods
37Addressing the pollution trap with taxes
38Lessons from CS (1/2)
- Solution changing the system structure
- Introducing new feedback loops
- information, incentives, regulations concerning
the state of resources, the surrounding
environments and producing communities - MUST be strong enough to counterbalance the
inherent pressure to increase efficiency, scale
and level of production
39Lessons from CS (2/2)
Designing interventions
- an intervention should deal with the core growth
drivers of a system - the more effectively it does so, the more likely
it is that it will neutralise more traps - the boundaries of the solution should match the
boundaries within which the commodity is produced
and sold - e.g. all of the producers selling into a given
market should participate in the agreement
40So... what ecological economics is about?
- Studying the interactions between economic
systems and the ecosystems that they are part of - Shaping those interactions so as to make them as
harmonious as possible
