3The Economic Importance of the Environment (BK
27)
- Environmental Economics
- The study of relationships of the importance of
the environment to the economy - Includes
- The impact of environment as a result of economic
activity - Regulation of the economy and economic processes
- The objective of balancing environmental and
economic goals of society - Development of economic policy to minimize
environmental degradation - Finding solutions to environmental problems
4Environmental D-making
- Decision making involves analysis of tangible and
intangible factors - Environmental economics task develop methods of
evaluating intangibles that - Provide good guidelines
- Easy to understand
- Quantitatively credible
5Case study Can mahogany be harvested sustainably
profitably?
- A highly valued wood native to Latin America
- Ecology affects production economics
- Seedlings need clearings 120 yrs for marketable
growth - Natural low density growth
- Traditional logging is selective, not enough
clearance for regrowth - Roads ? increased development ? rainforest
ecosystem threatened
6- Option 1 ban all mahogany products restrict
intl trade - Rainforest Action Network
- Critics say boycott ? devalues forest ?
encourages agriculture ? destroys forest - Option 2 logging carefully
- Rio Bravo, Belize experiment remove more trees,
but monitor ecological impacts by studying birds,
butterflies - Cost benefit analysis of harvest methods
- Critics say only 1/3 less destructive
- Option 3 grow mahogany in plantations leave
old-growth alone - International Institute of Tropical Forestry,
Puerto Rico - May not help livelihood of Latin American people
7The Environment as a Commons
- Commons
- Land or another resources owned publicly with
public access for private uses - People using common natural resources often do
not seek sustainability, despite long-term best
interestwhy??
8British Ocean Territory a commons
- Great Chagos Bank largest atoll
- Tuna fishery
- Coral reefs
- Biodiversity
9Short-term profits vs. long-term resource
sustainability
- Profit motive alone will not always promote
actions in best environmental interest 2
reasons - The tragedy of the commons Garrett Hardin,
ecologist - Personal profit share from exploitation gtgt loss
of resource - Low growth rate and thus low productivity of
resource - Maximizing immediate profit can seem reasonable
practical if low growth rate diminishes long-term
sustainable harvest of resource
10Whaling sustainability vs profits
Bowhead whales killed 1849-1914 low growth ?
exploitation
11Externalities
- Externality (Indirect Cost)
- An effect not normally accounted for in the
cost-revenue analysis of producers and often not
recognized by them as part of their costs and
benefits - Costs (or benefits) that dont show up in the
price tag - Direct Costs
- Those borne by the producer and passed directly
on to the user or purchaser - E.g. whaling externalities
- Loss of revenue to tourist boats
- Loss of ecological role in marine ecosystems
- Without true costs revealed, consumer cannot
behave rationally
12Consider Atmospheric pollution externality
- Problem 1 What is the true cost of clean air?
- Everyone agrees it to be larger than zero
- But, effectively traded and dealt with as if
value 0 - How to get value of clean air/water recognized
socially gt 0? - Quantitative evaluation of tangible resources
prior to development is standard procedure - Problem 2 Who should bear burden of these
costs? - Environmental ecological costs could be
included in production costs through fees or
taxation - Borne by corporation and/or consumer
- Or shared by entire society through general tax
13Natural capital
- Public service functions of Nature are often
overlooked, and not really valued until lost from
our environment - Forests absorb particulates salt marshes convert
toxic compounds wetlands treat sewage - Bees pollinate an estimated 20 billion crops
annually in US - Bacteria fix N and clean water air
- Estimates of economic value 3 to 33 trillion
per year! - Ecological systems providing these benefits are
natural capital - But what about (intangible) beauty of naturehow
do we arrive at a price, or assess value, of
landscape aesthetics?
14How is the future valued?
- Can we place a value on future existence of
anything? - Spending present on environment diverts
resources from other productive investment - With more wealth, we tend to value environmental
assets moreso is conserving now robbing the poor
for future rich?
General rule dont discard or destroy anything
irreplaceable if you are unsure of future value.
15Risk-Benefit Analysis
- Evaluation of the riskiness of a present action
in terms of its possible outcomes - Acceptable risk is socially, ethically,
psychologically relative - How much are we willing to pay to reduce risk?
- We tend to accept higher levels of risk for
non-essential activities (e.g. recreational
sports) - Impossible ethically to put value on human life,
but we can survey amount people are willing to
pay for certain risk reduction or probability of
longevity (e.g. Rand Co. 32,000/life
1600/year) - The relation between risk and benefit affects our
willingness to pay for an environmental good
16Do we improve quality of life (reduce pollution)
for living or extend life expectancy regardless
of quality of life?
17- Evaluation of environmental intangibles is
becoming more common in environmental analysis - When quantitative, such evaluation balances the
more traditional economic evaluation and helps
separate facts from emotion in complex
environmental problems - Take a Closer Look at Risk Benefit analysis
and DDT (BK 27.1 p. 593)
18How Do We Achieve an Environmental Goal?
- Means to implement a societys policies are
policy instruments - Moral suasion (publicity, social pressure)
- Direct controls (regulations)
- Market processes (prices, taxes, subsidies,
licenses) - Government investment (research education)
- Many controls have been applied to the use of
desirable resources and the control of pollution
19Marginal Costs and the Control of Pollutants
- Marginal Costs the cost to reduce one additional
unit of pollutant - Often increases rapidly (e.g. exponentially for
BOD reduction from petroleum refining) as
reduction percentage increases - 3 methods of direct control of pollution
- Setting maximum levels of emission
- Needs careful monitoring costly, difficult
- Requiring processes and procedures
- Required methodology may cost lots, restrict
production, or go obsolete - May increase efficiency (e.g. Japan uses only 5
MJ/1 GDP, while US uses 12 MJ) - Charging fees for emission

22Ecotopia qualities
- A stabilized or even decreased population
- Sustainable living resources and harvest
- Recreation enjoyment of nature open to all,
with minimized pollution - Risk of species extinction minimized
- Enough public servicing ecosystems
- Enough wilderness for recreation
- Sustain representatives of natural ecosystems in
dynamic ecological states
23...if you reflect on our change from thoughtless
trash-tossing to virtually universal recycling,
or from the past in which smokers didn't hesitate
to blow smoke in anybody's face to our present
restrictions on smoking in public places, it's
clear that shared ideas about acceptable or
desirable behavior can change markedly. Such
changes occurred without anybody getting arrested
in the dark of night. Further changes will
come... Ernest Callenbach, 1975
24Developing a sustainable future A new paradigm
- Evolutionary, not revolutionary
- Change in values involving lifestyle, social,
economic environmental justice - Inclusive, not exclusive
- All people of Earth to higher standard of living
without compromising environ - Proactive, not reactive
- Plan for change events rather than awaiting
surprises - Attracting, not attacking
- Sound science appropriate values should be just
right - Assisting the disadvantaged, not taking advantage
- All people have a right to live work in safe,
clean environment
25Planning a nations landscapes
- What is necessary at a national scale to achieve
goals? - John Wesley Powells vision organized around
watersheds, not state boundaries use but not own
or sell water - 1902 Congress water rights sold large dams
canals constructed
26The Wildlands Project
- America needs rewilding
- Larger parks needed for umbrella species of
large predators - Managed around big predators, providing core
areas, corridors buffers - Controversy of science values
- fundamental threat to democracy?
- Flawed science?
27Process of future planning
- Two qualities of formal land use planning
processes - A set of rules requiring paper work procedures
- An imaginative attempt to use land resources in
beautiful, economically beneficial and
sustainable ways - All human civilization plans land use planning
is a social experiement - Democracy involves tug-a-war between individual
freedoms and societal welfare - Who speaks for nature? Who legally represents the
environment?
28Regional planning (TVA)
- 20th century experiment crossing state boundaries
- Tennessee Valley Authority (TVA) 1933
- One of worlds best examples of regional planning
- FDR vision as govern corporation with flexibility
initiative - Multidimensional multilevel planning to manage
land water resources - Electrical power, flood control, navigation,
recreation - Central authority with considerable public input
29The TVA
Raccoon Mountain Dam
30Environment law
- US legal system derived from British common law
system - Custom, judgment, court decrees instead of
legislation - Protect individual freedom just give me a
little land, a horse, and a gun and leave me
alone. - A caveat when individual behavior infringed on
the property or well-being of others - Public trust doctrine government is public
guardian of natural resources
31History of federal environmental law
- 3 stages
- Convert public lands to private uses (early 19th)
- Conserved public lands for recreation, beauty,
historic preservation - National parks
- US Forest Service
- Primary environmental laws
- NEPA 1969 ? Water Quality
32Who stands for nature?
- 2 widely supported moral positions
- Public lands (resources) must be open to public
use, and resources for economic benefit - Public lands should serve society first,
individuals secondly
33Skiing at Mineral King
Should our ethical values be extended to
non-human?
34How you can be an actor in legal processes
- Environmental litigation more access to courts ?
policy - Citizen actions
- Environmentalism to ecotage
- Civil disobedience
35Case Protecting Forests
- Julia Hill spent 2 years (1997-1999) in a 1000
year old redwood tree to prevent it from being
logged.

36Mediation
- Negotiation between adversaries guided by neutral
facilitator - Classic case Storm King Mountain, Hudson River
- 1962 hydro plant
- 1965 lawsuit
- 1981 settlement
37International environmental law diplomacy
- No world government with enforcement authority
- Agreement with multinational issues
- Montreal Protocol, 1987, ozone
- Antarctica White Continent
38International Environmental Laws
- Montreal protocol (1987)
- international agreement to phase out
stratospheric ozone destroying CFCs. - Persistent Organic Pollutants
- persist in the environment, bioaccumulate through
the food web, and pose a risk of causing adverse
effects to human health and the environment - Polychlorinated biphenyls (PCBs) liver damage,
cancer - Following several years of negotations, 127
nations in 2001 adopted a treaty to greatly
reduce the use of toxic chemicals known to
contribute to cancer and harm the environment. - Kyoto Protocol (1997)
- Reduction of CO2 air pollution
- Not ratified by US and Australia
39Global security environment
- Terrorism comes in part from poverty,
overcrowding, disease conflicts that have
environmental significance - Over 1 billion live in poverty with little hope
- 1992 Rio Earth Summit on Sustainable Development
objective global environmental vs. economic
problems - Wealth gap is growing
- Environment remains under-funded

41International Environmental Summit Meetings
- The UN has sponsored several meetings on
environmental issues - Rio de Janeiro, Brazil, 1992
- The Rio Conference was a significant milestone
that set a new agenda for sustainable
development. - A major theme was perceived threat of global
warming. - Kyoto, Japan, 1997
- Johannesburg, South Africa, 2002
- Climate Change Conference, Montreal, 2005
42US Role in Sustainable Development
- Rio de Janeiro, March 24, 1992
- The Bush I administration fears Greenhouse gas
limits hinder economic growth - Kyoto, Japan, 1997
- On October 22, 1997, Clinton announced that he
would seek the establishment of an international
emissions trading scheme as an alternative to
carbon taxes as a means of reducing world
emissions of greenhouse gases. - Johannesburg , 26 February 2002
- American environmentalists urged President G. W.
Bush to announce that he will go to Johannesburg
to join with other countries in partnerships that
can address the environmental challenges
threatening long-term well-being and security. - G. W. Bush sent Powell
- Current US position on sustainable development is
non-committal.
43United Nations Climate Change Conference agrees
on future critical steps to tackle climate change
- Montreal, 10 December 2005 - The United Nations
Climate Change Conference closed with the
adoption of more than forty decisions that will
strengthen global efforts to fight climate
change. - The US is remains outside of the process
44Earth SummitJohannesburg, South Africa, 2002
Read Johannesburg Declaration on Sustainable
Development
45Outcome of Johannesburg Summit
- New York, 25 September 2002
- When the United Nations General Assembly
authorized holding the World Summit on
Sustainable Development, it was hardly a secret
that progress in implementing sustainable
development has been extremely disappointing
since the 1992 Earth Summit, with poverty
deepening and environmental degradation
worsening. What the world wanted, the General
Assembly said, was not a new philosophical or
political debate but rather, a summit of actions
and results. - UN Division of Sustainable Development website
46Earth Summit on Sustainable Development 2002
- Continue work toward environmental social
justice for all people - Enhance the development of sustainability
- Minimize local, regional global environmental
degradation - Develop support international agreements to
control global warming pollutants
47Challenge
- Solving our environmental problems will help
build a more secure sustainable future - As university graduates you will take on
responsibility of transferring environmental
knowledge taking responsible leadership
48Motivation
- present practices of energy and resource
consumption are non-sustainable - What on Earth will we leave for future
generations?
49Non-sustainability
- An estimated 80 percent of global fish stocks are
now fished at or beyond their sustainable limit. - Despite the existence of alternative sources,
more than 90 percent of paper still comes from
trees - eating up about one fifth of the total
wood harvest worldwide. - Around 1.7 billion people worldwide - more than a
quarter of humanity are entering the "consumer
class," - adopting the diets, transportation systems, and
lifestyles that were limited to the rich nations
of Europe, North America, and Japan during most
of the last century. - In China alone, 240 million people have joined
the ranks of consumers - a number that will soon
surpass that in the United States.

50Sustainability
- We could have a sustainable world of 8 billion
with the average standard of living now found in
Europe for all people by - controlling population growth
- increasing fuel efficiency
- increasing reliance on renewable energies
- controlling pollution
- Scrubbers
- Reforestation
- Carbon sequestration
- promoting environmental protection
51Less is more
- Consumption
- "You don't own your possessions, your possessions
own you. - Urban redevelopment
- Less land consumed
- Driving Less
- Increased cash-flow
- More time
- Better health
- auto-related injuries In 2002
- 2.9 million nationally
- 42,815 deaths
- 800 / week
- 1,400 in Ohio.
- Less stress
- decreased freedom?
52Books on SimplyLiving.net
53more consumption ? more happiness
- About a third of Americans report being "very
happy," the same share as in 1957, when Americans
were only half as wealthy. - Today, Americans are among the most worked people
in the industrial world - nine more weeks on the job each year than the
average European.

54Annual Conference of The Club of Rome in
co-operation with The Arab Thought Forum "In
Search for Common Ground for Peace and
Development8-10 October, 2003Amman, Jordan
55Final Statements from Annual Conference of The
Club of Rome
- Although there was hope that the process of
globalizing markets would lead to more equity and
the socio-economic inclusion of the poor, this
has not come true. On the contrary, we are facing
the crucial fact that the rich have become
richer, the poor poorer. - In the US, the top 5 percent has more wealth than
the remaining 95 percent of the population put
together.

57Closing Thoughts
- optimistic view
- as the human population approaches the actual
carrying capacity, there will be sufficient
signals and we will collectively act on those
signals in such a way as to prevent an overshoot
and collapse from occurring. - Evidence suggests we may have reached carrying
capacity not just through population growth, but
by increased consumption
58- signals of overshoot
- increasing prices for natural resources, which
encourage a reduction in use through
conservation, recycling, and increased
efficiency. - fossil fuels we rely on for most of our energy
are produced too slow - we cannot achieve a steady state condition for
these energy resources. - Thus, we will ultimately have to get all of our
energy from sustainable sources such as solar,
wind, and nuclear sources (nuclear fusion rather
than fission, whose waste products are too
problematic). - Solar is the most attractive resource
59- example of how this adaptation can work
- the case of the 1970s energy crisis
- rapid changes occurred in response to the
decrease in availability of petroleum. - Unfortunately, most of these changes were
reversed shortly after, once the flow of oil from
the OPEC countries continued. - we can change if we are convinced that we must
- especially if it is economically favorable to
change.
