Title: Ecological Economics and Applied Problem Solving
1Ecological Economics and Applied Problem Solving
2What is Economics?
- The allocation of scarce resources among
alternative desirable ends - What are the desirable ends?
- What are the scarce resources?
- What is the nature of these scarce resources?
- How do we allocate?
3Transdisciplinarity
- We are dealing with the issues at the interface
of two highly complex and interconnected systems - Cant be understood from perspective of one
discipline alone. - Specific problem must determine appropriate
methodologies, not vice versa.
4I. What are the Desirable Ends?
5Desirable Ends
- A high quality of life for this and future
generations, which requires - Ecologically sustainable scale
- Just distribution of resources within and between
generations - Efficient use of resources
6- II. What are the scarce resources?
7 First law of thermodynamics
- Matter energy cannot be created or destroyed
- We cannot create something from nothing, nor
nothing from something - All economic production requires natural capital
- Continuous physical growth of the economy is
impossible
8 Second law of thermodynamics
- Entropy never decreases in an isolated system
- Things fall apart, wear out, become waste
- Irreversible, evolutionary, qualitative change
- There is only a finite stock of accumulated low
entropy - The ultimate limit to the physical size of the
economic system is the low entropy provided by
solar energy
9What is scarcer, natural or manmade capital?
10Conclusions
- The ultimate scarce resource is a finite supply
of low entropy matter/energy - It will not increase in response to price
increases - Natural capital has become the scarcest resource
11III. What are the market relevant characteristics
of scarce resources?
12Three important characteristics
- Ecosystem goods vs. ecosystem services
- Excludability can it be owned?
- If not, the market wont provide it
- Rivalness does it wear out when we use it?
- If not, the market shouldnt provide it
13Ecosystem goods
- Raw materials ecosystem structure
- Production material transformation
- Used up, not worn out use depletion
- Rate of flow can generally be controlled
- Characterized by risk
14Ecosystem services
- Structure generates function ecosystem services
- Not transformed into what it produces
- Spontaneously restored
- Rate of use cannot be controlled
- Characterized by uncertainty and ignorance
15So What?
- Raw material extraction depletes ecosystem
services - Waste output depletes ecosystem services
- Services from nature include life support
functions - We cannot treat ecosystem goods and services
independently
16So How do We Allocate?
17When do markets work?
Excludable
Non-Excludable
Open Access Regime Oceanic fisheries,
timberetc. from unprotected forests, waste
absorption capacity
Market Good land, oil, timber, captured fish,
waste absorptioncapacity?
Rival
Potential market good but inefficient patented
information, e.g. energy efficiency, pollution
control tech.
Pure Public Good Information, most ecosystem
services, e.g. climate stability, coastline
protection, life support functions, etc.
Non-rival
18Macro-allocation
19Allocation of non-market goods
- Requires participatory democratic decision making
process - Just distribution therefore applies to political
power as well as resources
20Case Study Conversion of Mangrove Ecosystems to
Shrimp Aquaculture
21Site location
22Project design
- Case study
- Developed in close collaboration with local
partners - NGOs ELAC, PRRM, Tambuyog, ISANet, APEX
- Local Government
- Community representatives
- Local University
- Multiple disciplines represented
23Desirable ends
24Quality of life
- For who?
- Local
- Indigenous community
- Tagabinet villagers
- Coastal fishing communities
- National seafood supply
- Global carbon sequestration, biodiversity
preservation
25Scale and distribution
- 70 of mangroves in Philippines lost
- Intact mangroves provide public goods, common
resources for community - Shrimp aquaculture benefits owners and American
consumers
26Working with Stakeholders
- Framing the problem
- Local knowledge
- Stakeholder values
27Scarce resources from ecosystem
- Ecosystem goods
- Building materials
- Food
- Ecosystem services
- Coastline protection
- Waste absorption
- Nursery
28from conversion
- Shrimp and fish for 3-5 years
- Less protein than intact ecosystem
- Massive waste output
- Irreversible(?) destruction of ecosystem
29Synthesis and Communication
30Leads to Action
- Press conference on site, with owners, community
members, local government, representatives of
federal government - Illegal dikes torn down by community members
31 and efficient allocation
