1
Ecological Economics and Applied Problem Solving
2
What 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?
3
Transdisciplinarity We are dealing with the issues at the interface of two highly complex and interconnected systems Can’t be understood from perspective of one discipline alone. Specific problem must determine appropriate methodologies, not vice versa.
4
I. What are the Desirable Ends?
5
Desirable 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 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 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
9
What is scarcer, natural or manmade capital?
10
Conclusions: 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
11
III. What are the market relevant characteristics of scarce resources?
12
Three important characteristics Ecosystem goods vs. ecosystem services Excludability– can it be owned? –If not, the market won’t provide it Rivalness– does it wear out when we use it? –If not, the market shouldn’t provide it
13
Ecosystem 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
14
Ecosystem 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
15
So 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
16
So How do We Allocate?
17
When do markets work? Rival Non-rival ExcludableNon-Excludable Market Good: land, oil, timber, captured fish, waste absorption capacity? 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. Open Access Regime: Oceanic fisheries, timber etc. from unprotected forests, waste absorption capacity
18
Macro-allocation
19
Allocation of non-market goods Requires participatory democratic decision making process Just distribution therefore applies to political power as well as resources
20
Case Study: Conversion of Mangrove Ecosystems to Shrimp Aquaculture
21
Site location
22
Project 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
23
Desirable ends
24
Quality of life For who? –Local Indigenous community Tagabinet villagers Coastal fishing communities –National: seafood supply –Global: carbon sequestration, biodiversity preservation
25
Scale and distribution 70% of mangroves in Philippines lost Intact mangroves provide public goods, common resources for community Shrimp aquaculture benefits owners and American consumers
26
Working with Stakeholders Framing the problem Local knowledge Stakeholder values
27
Scarce resources from ecosystem Ecosystem goods –Building materials –Food Ecosystem services –Coastline protection –Waste absorption –Nursery
28
…from conversion Shrimp and fish for 3-5 years Less protein than intact ecosystem Massive waste output Irreversible(?) destruction of ecosystem
29
Synthesis and Communication
30
…Leads 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
