Title: Economics and Ecology:


1
Economics and Ecology
  • Specialize, Separate, and Reintegrate

Chrissie Nims
2
The Reductionist Paradigm
  • The world can be divided into isolated units and
    can be studied separately and put back together
    to see the whole picture.
  • This procedure reduced the connection between
    areas of study.

3
A Change in Ecology and Economics
  • Economics
  • The economics departments rewarded economic
    theory rather than actual application.
  • Economics textbooks mainly focused on supply and
    demand, and no longer discussed the connection to
    the natural environment.
  • Ecology
  • There was a split from the study of biology into
    zoology and botany.
  • Although it is necessary to include many systems
    when observing ecosystems, the majority of
    ecologists view the study of humans as a part of
    the social sciences.

4
The Reintegration of Ecology and Economics
  • In the 1980s it was found that the well being of
    future societies was based on the upgrade of
    environmental policies.
  • Ecological economics was considered the
    connection between ecologists and economists to
    apply new policies to help prevent environmental
    degradation.

General System Theory
  • One might define systems analysis as the
    scientific method applied both across and within
    disciplines, scales, resolutions, and system
    types.
  • This type of analysis uses mathematical modeling
    and is very complex. The availability of
    computers and technology promotes the process of
    systems analysis.

6
Open-Access Resource Management
  • A resource with many users is often exploited
    when there are no rules to govern its
    availability. Disaster often occurs if common
    governing institutions disintegrate.
  • Generally this disaster happens as society moves
    from a traditional to a more modern form.
  • For example, in order to prevent further
    environmental degradation, it is necessary to
    have a common regulatory institution for the
    global climate.

7
Energetics and Systems
  • Due to many of the oil crises that the world
    experienced, the role of energy in the economy
    was realized.
  • Georgescu Roegen Economic process uses energy
  • ENTROPY LAW Available energy in a closed system
    can only decline.
  • Criticssay that the earth is not a closed system.

8
Spaceship Earth and Steady-State Economics
  • Frontier economics growth in human welfare
    means growth in material consumption.
  • Spaceship economics growth in human welfare
    does not necessarily come by material
    consumption.
  • Steady-state economics the Earth is materially
    finite and non-growingthe economy is a subset of
    this finite global system and cannot grow
    forever.
  • Herman Dalys steady-state economy lead the way
    for ecological economics.

9
Adaptive Environmental Management
  • Involves the integration of science and
    management.
  • Holling claims that the management process must
    be experimental and must constantly adapt its
    policies because ecosystems evolve and change
    over time.
  • Adaptive environmental management is an
    established beneficial method in monitoring
    complex systems.

C.S. Holling (Canadian Ecologist)

Co-evolution of Ecological and Economic Systems
  • Each subsystem (knowledge, values, organization,
    technology, environment) is related to each of
    the others yet each is also changing and
    affecting change in the others through
    selectionWith each subsystem putting selective
    pressure on each of the others, they co-evolve in
    a manner whereby each reflects the other.
  • Co-evolutionary explanation of the
    unsustainability of modern societies
  • Hydrocarbons permit people to control their own
    environments while influencing the global
    environment and causing long term implications.

11
The Role of Neoclassical Economics in Ecological
Economics
  • Neoclassical market analysis is still an
    important pattern of thinking in ecological
    economics. Generally, neoclassical economists
    believe that technological advance will outpace
    resource scarcity.
  • On the other hand, ecological economists view
    more severe ecological limits and are doubtful
    that technology can help the economic disasters
    caused by resource scarcities.
  • Ecological economics uses the framework of
    neoclassical economics but is not constrained to
    use only that framework.

12
Increased Efficiency and Dematerialization
Ecosystem Health
  • In general, only individual species have been
    managed
  • INEFFECTIVE!
  • Ecological Economics looking toward prevention
    and anticipating broad disturbances.
  • Conservation biology instead of studying the
    downward trend of biodiversity, save the species
    from extinction.
  • The need to get more from less
  • Dematerialization by stabilizing the rate of
    material throughput in the economy.

13
Environmental Epistemology
Political Ecology
  • The philosophy that studies how we think we can
    learn truth.
  • Human Problem
  • Basic thought that nature is predictable and that
    it reacts along the lines of universal principles.
  • New field of political ecology formed by Marxist
    anthropologists, economists, historians, and
    sociologists.
  • The environmental crises of the latter half 20th
    Century have stimulated new critiques of
    capitalism.

14
Conclusion
  • Ecological economics has united many fields of
    study and has shown doubt in traditional notions.
  • Since the earth has a limited capacity for
    sustainably supporting people and their
    artifacts, new institutions and environmental
    policies are necessary to keep the economy within
    that capacity.

15
Discussion Questions
  • Do you think that Earth is a closed or open
    system?
  • Does the neoclassical approach of economic growth
    diminishing the inequality between the rich and
    the poor speak true to you?
  • The management of individual species is said to
    be ineffective. Do you agree/disagree?
