Chief Seattle's Speech of 1854 (Version 1) Dr.
Henry A. Smith, Seattle Sunday Star, Oct. 29,
1887)
(..) Our religion is the traditions of our
ancestors - the dreams of our old men, given them
in solemn hours of the night by the Great Spirit
and the visions of our sachems, and is written in
the hearts of our people. (..). Our dead never
forget this beautiful world that gave them being.
They still love its verdant valleys, its
murmuring rivers, its magnificent mountains,
sequestered vales and verdant lined lakes and
bays, (..)

Environment
  • Concern about the environment in Europe started
    about 20 years after WW-2, that is, the post-war
    generation
  • Radioactive fallout (atmospheric atomic bomb
    explosions USA ex-USSR)
  • Heavy metal contamination Cadmium (itai-itai
    disease) and Lead (Minamata Bay)
  • Organic micro-pollutants, pesticides,
    Phosphorus, Nitrogen, acid deposition, etc
  • Emission of gases that cause climate change
    gases that break down the ozone layer

10
Environ-ment
11
Biodiversity
  • Eutrophication of surface water (N P) fish
  • Acid deposition (NH3, NOx, SOx) forests
  • Use of biocides disappearance of plant and
    animal species (frogs, storks, birds of prey)
  • Habitat destruction, e.g., deforestation
    disappearance of plant and animal species
  • Over-fishing of seas and oceans
    disappearance of fish species

12
Limits to Economic Growth
  • Industrialization
  • Population growth
  • Malnutrition
  • Non-renewable resources
  • Environment
  • Club of Rome, Limits to Growth, 1972

13
Social Political Issues
  • Cold war
  • Decolonization process
  • Racial emancipation (USA)
  • Emancipation of women
  • Democratization from the state level to the
    workplace (e.g., universities, factories)
  • Mass media ICT Television, Internet, Cell
    Phones
  • Globalization Economy, Information

3. Sustainable Management of Natural Resources
15
  • Define the system in terms of its components and
    metricized parameters
  • Soil chemical, physical, biological parameters
  • Ground- and surface water chemical, biological
    parameters
  • Air chemical parameters
  • Above- and below-ground biodiversity
    ecosystems biological parameters
  • gtgt Define functions and services !!

16
  • Functions
  • Culture or production function
  • Filter or buffer function
  • Ecological functions
  • Services
  • Provide clean water, refugium for biota, food of
    good quality, recreation, etc

17
  • Measure individual parameters, functions,
    services, metrics quantify them and compare
    against set criteria.
  • How do the individual parameters change over
    time? Portfolio picture.
  • How does the management system affect the
    resource base? Renewable non-renewable
    resources.
  • Is the management system economically viable?
    Culturally and socially acceptable? Policy
    environment? Institutions?
  • Is the management system sustainable ?

  • Sustainability
  • Dynamic quality processes (x,t)
  • Dynamic concept relates to processes, not to
    static parameters
  • Processes are functions of time (t) and space
    (x,y.z)
  • ?Time scale Space scale are important
  • ? Up-scaling extrapolation Agro-Ecological
    Zoning, simulation modeling, dynamic systems
    analysis

5. Globalization
30
Globalization (1) Relates primarily to economic
relations multinational companies move their
production units to countries with low wages and
little or no social or environmental legislation
(or enforce-ment of any existing legislation).
In a political and cultural sense, globalization
has been perceived as spreading western values
and consolidating global power structures The
anti-globalization movement and NGOs may have
contributed more to conservation of the
environment and biodiversity than the
globalization per se
31
Globalization (2) Science and technology always
have been international cq global, but this has
been facilitated by improved travel facilities
worldwide and the upsurge in information and
communication technologies, facilitating
increased access to knowledge and technology Some
countries in SE and E Asia seem to have benefited
significantly of the opportunities provided by
economic globalization. More recently, China and
India seem to be solidly on the path of economic
development, their growth being clearly linked to
economic globalization.
32
Globalization (3) The poorest countries do not
seem to benefit much from economic globalization
(other than providing cheap labour), their
environment may be further degraded by polluting
industries, and only the urban elite seems to
benefit from the ICT and other positives of
globalization. Nevertheless, some countries
(e.g., Ghana) have realized sustained economic
growth over the past decade and it remains to be
seen whether this development model can deal
effectively with rural poverty and
underdevelopment
