Title: Discordance between ecological and political systems


1
Discordance between ecological and political
systems
  • Defining Resources
  • What is a natural resource?
  • An entity having some recognized human use.
  • (Rees) 2 pre-conditions
  • knowledge technology must exist to allow
    extraction use
  • must be a demand for materials or services
    produced
  • Therefore, human ability and need create resource
    value, not mere physical presence.

2
  • (Cutter Renwick) Resources are determined by
    combination of technology, economics, social
    conditions/lifestyles, environmental ethics,
    cultural background, and issues of scarcity
    ownership.
  • Natural resource
  • Implies that it exists independent of human
    activity. Ex (plants, seeds, wildlife, trees,
    soil, water, air, sun, rivers, etc.)

3
  • Key point I
  •  
  • Resources are socially constructed (or socially
    defined) and dynamic entities.

4
Classifying Resources 2 schemes
  • 1. Resource Ownership Characteristics
  •  
  • Common Pool vs. Private Property
  • Traditional commons
  • Public lands resources
  • Global commons

5
  • B. Resources Availability Characteristics
  • 1. Perpetual inexhaustible supply.
  • ex.) the sun
  • 2. Renewable (Flow)
  • ex.) fisheries, forests, soil, ground water, air
  • 3. Nonrenewable (Stock)
  • A finite supply, or renewal rate not significant
    in relation to our use and consumption.
  • ex.) fossil fuels, mineral ores, arable land,
    wilderness
  • 4. Potential exist, but not yet discovered
  • Ex.) solid waste as alternative fuel

6
  • The dynamism of resources categories
  • Categories often determine policy, yet are
    subject to change
  •  
  • Key Factors
  • Rate of Consumption vs. Rate of Regeneration
  • As rate of consumption surpasses rate of
    regeneration, a renewable becomes
    non-renewable

7
The Scarcity Debate
  • Malthus vs. Engels
  •  
  • Ricardo, the law of diminishing returns.
  •  
  • Ehrlich vs. Simon.

8
  • These debates over resource definitions
    illustrate
  • Key point II
  • The differences (or discordance) between
  •  How ecological systems actually operate
  •  vs.
  • How we understand them to work, categorize them,
    make management decisions

9
  • Result a multitude of environmental crises
    disputes
  • Z. Smith the env. policy paradox
  • D. Botkin arguments in Discordant Harmonies

10
Some Ecological Concepts
  • Ecology
  • the study of interrelationships between animals
    and plants and the living and non-living
    components and processes that make up their
    environment. (Cutter Renwick)

11
  • Ecosystem
  • a relatively coherent system in which matter and
    energy are exchanged among living and non-living
    organisms and with the larger environment.
  • often difficult to define with precision
  • Ex. Watershed or even urban area
  • Bounded by ecotones or transition zones
  • nested hierarchy
  • Communities
  • Ecosystems
  • Biomes or bioregions
  • Biosphere

12
Commoners 4 Laws of Ecology
  • Interconnectivity
  • Effects of actions reverberate through system as
    a whole. (ex. food chains/trophic levels)
  • Everything must go somewhere
  • Actions produce residual outcomes
  • Nature knows best
  • Human knowledge is insufficient to determine full
    effects of interactions
  • Theres no such thing as a free lunch.

13
Discordant Harmonies
  • The current dilemma
  • The potential for us to make progress with
    environmental issues is limited by the basic
    assumptions that we make about nature, the
    unspoken, often unrecognized perspective from
    which we view our environment. p. 5

14
  • How our perceptions must change
  • Acknowledge dynamic rather than static properties
    of the earth
  • Adopt a global view

15
  • The Problem
  • Ancient views of nature
  • Example of climate change
  • Difficulty of dealing with dynamism
  • Notions of steady state, climax stages
  • Elephants in Tsavo
  • Fisheries Maximum Sustainable Yield
