Economic Growth as the Limiting Factor for Wildlife Conservation Including Considerations of Technological Progress

Compliments of Brian Czech This presentation is based on: Czech, B. 2000. Shoveling Fuel For A Runaway Train: Errant Economists, Shameful Spenders, And A Plan To Stop Them All. University of California Press, Berkeley. Czech, B. 2000. Economic growth as the limiting factor for wildlife conservation. Wildlife Society Bulletin 28(1):4-14. Czech, B., P. R. Krausman, and P. K. Devers. 2000. Economic associations among causes of species endangerment in the United States. BioScience 50(7):593-601. Czech, B., and P. R. Krausman. 2001. The Endangered Species Act: History, Conservation Biology, and Public Policy. Johns Hopkins University Press, Baltimore, MD. Based largely on: Czech, B. 2000.

Under Review.
3
Economic Growth an increase in the production and consumption of goods and services typically expressed in terms of GDP facilitated by increasing: –population –per capita consumption
4
The Theoretical Framework
5
Time GNP K Natural capital allocated to human economy Natural capital allocated to wildlife Czech, B. 2000. Economic growth as the limiting factor for wildlife conservation. Wildlife Society Bulletin 28(1):4-14.

Some Empirical Evidence: Causes of Species Endangerment as a “Who’s Who” of the American Economy
8
Endangerment Causes Urbanization Agriculture Water diversions (e.g., reservoirs) Recreation, tourism development Pollution Domestic livestock, ranching 247 205 160 148 143 136 Czech et al. 2000. Bioscience 50(7):593-601.
9
Causes (cont.) Mineral, gas, oil extraction Non-native species Harvest Modified fire regimes Road construction/maintenance Industrial development 134 115 101 83 81 Czech et al. 2000. Bioscience 50(7):593-601.

Making sense of the Who’s Who with Trophic Theory
15
Basic Population Dynamics
16
K Carrying Capacity Scenarios Individuals Time r-selection K-selection
17
K and r-selected Species
18
K Economic Carrying Capacity GNP Time r-selection K-selection
19
K and r-selected Economies
20
American GNP, 1929-1997 K or r-selected?
21
But, for the sake of wildlife conservation, it’s not enough to hope we’re a K-selected economy.
22
K Wildlife Conservation and Steady State Economy GNP Time...maintain steady state economy sufficiently below K. To conserve wildlife...
23
But what about Technological Progress?
24
Technological Progress Vernacular: invention, innovation Technical: increasing productive efficiency resulting from invention and innovation
25
KTKT GNP Natural capital allocated to human economy Natural capital allocated to non-human economy X natural capital allocable Time KUKU Natural Capital Allocation Revisited
26
X/2 conserved K1K1 K2K2 GNP Time X natural capital remains allocable KUKU Economic growth with technology level 2 Economic growth with technology level 1 The Big Hope
27
The Great Debate: Is There a Limit? “Yes” Physiocrats Classical economists Ecological economists Ecologists “No” Neoclassical economists Corporations Politicians
28
Why would there not be a limit? Substitutability of resources Increasing productive efficiency Increasing human capital
29
White Pine, “Big Wheel”
30
Substituting for white pine, employing more efficient technology.
31
Sitka Spruce, Timbco 435 “Feller Buncher”
32
Why would there be a limit? Carrying capacity Thermodynamics Trophic levels
33
Carrying Capacity Consumers Products Byproducts
34
Thermodynamics Fixed amount of matter Entropy Fixed amount of energy
35
Another look at trophic levels, this time in light of thermodynamics.
38
Clear to All Without technological progress, GNP limited GNP growth faster than technological progress = trouble
39
Unclear to Many Technological progress: raising the bar or accelerating the approach? Does technological progress occur without increased consumption?
40
Consider the Sources Research and development Corporate profit Economies of scale
41
KTKT GNP Natural capital allocated to human economy Natural capital allocated to non-human economy X natural capital allocable Time KUKU One More Look at Allocation
42
X/2 conserved K1K1 K2K2 GNP Time X natural capital remains allocable KUKU Economic growth with technology level 2 Economic growth with technology level 1 Remember the Big Hope?
43
K1K1 K2K2 GNP Time X/2 natural capital allocable KUKU X/2 converted Economic growth with technology level 2 Economic growth with technology level 1 The Apparent Reality
44
Red Herring Alert! Red Herring Alert! Red Herring Alert!
45
The “Information” Economy But just ask 2 questions: What is the information used for? How does one come to afford the information?
46
To say that an economy may grow perpetually on a finite land mass is to say that a stable economy may occupy a perpetually diminishing land mass! Fallacy Buster
47
= $ $ $ $
48
Real Questions What is the limit? How do we know when we’re approaching the limit? What do we do to prevent breaching the limit?
49
And yet we hear: “Some people just don’t get it. There is no conflict between economic growth and environmental protection!” Why do they persist?
