3. Sustainable Development
■The issue
•Brought forward in view of challenges at a scale never seen
before.
•Demographic challenge:
•Strong population growth, notably in the developing world.
•Resource challenge:
•An increasing usage of resources, renewable and non renewable alike.
–Raw materials.
–Energy.
–Food.
•Environmental challenge:
•Higher levels of environmental impacts of human activities.
•The capacity of this world to sustain its population is
compromised.

4. Sustainable Development
■“Sustainable”
•The process or the activity can be
maintained without exhaustion or
collapse.
•Intra and Inter-generational issue.
•Capacity of a system to accommodate
changes:
•Rates of use of renewable resources
should not exceed their rates or
regeneration.
•Rates of use of non-renewable
resources should not exceed at which
renewable substitutes are developed.
•Rates of pollution emissions should not
exceed the assimilative capacity of the
environment.

5. Sustainable Development
■“Development”
•Development is about people, not necessarily the economy.
•Development is a process.
•Improvement of the welfare of the population:
•Create an enabling environment for people.
•Often forgotten in the immediate concern with the accumulation of
commodities and wealth.
•Finding ways to satisfy and improve human needs.

6. Sustainable Development
■Conditions:
•Appropriate social, political, legal
and economic conditions.
■Outcomes
•Improvement of the physical and
human capital.
•Human capital:
•Improved health or knowledge.
•Improved opportunities for people
to use their acquired capabilities.
•Improved work or leisure
conditions.
•Physical capital:
•Improved private infrastructures.
•Improved collective
infrastructures.

8. Sustainable Society
■Three “E”s
•Economics.
•Ecology / Environment.
•Equity (social).
■Population
•Lessen population growth and stabilize it (preferably).
•Stop subsidizing reproduction.
•Access to contraception and family planning (freedom of choice).
•Basic material needs satisfied (social obligation?).
•Political and gender equity.
•Access to information and education.
2

9. Sustainable Society
■Ecology
•Restore the biological base (soils, forests, atmosphere and
hydrosphere).
•Agriculture supporting ecosystems (diversity and organic
recycling).
■Energy
•Minimize and abolish fossil fuels (market forces are likely to do
so).
•Shift to natural gas as an interim measure.
•Move to renewable energy sources (hydrogen, solar, wind,
geothermal, biomass and hydroelectric).
2

10. Sustainable Society
■Economy
•Promotion of efficiency and recycling.
•Source materials mainly recycled materials.
•Reduce wastes in production, packaging and distribution.
•Economy like an ecosystem.
•Dematerialization of the economy.
■Spatial forms
•Rational use of space (market forces).
•Dense and compact cities.
•Multifamily dwellings.
•Alternative transportation modes:
•Leaning on mass transit, cycling and walking.

12. Sustainable Society
■Social forms
•Material sufficiency and frugality:
•Replacing consumerism and materialism (unlikely).
•Living according to one’s means.
•Self-worth and social status:
•Not measured primarily by possession (unlikely).
•Balance between individual rights and obligations:
•End of social welfare and the irresponsibility it creates?
■Governance
•Less government and more individual initiative.
•Global governance (common policies for common causes).
•Regional autonomy (regional issues and cultural / political
differences).
•Avoid socialism and fascism (especially “world improvers”).

13. Global Sustainability

•Maximize profit
•Expand markets
•Externalize costs
•Respect carrying capacity
•Conserve and recycle
resources
•Reduce waste
•Satisfy needs
•Increase self-reliance

16. General Indicators: What the Market Can Do
Energy and air
quality
New sources of energy. Less energy intensity. Lower
emission levels.
Water, materials and
waste
Less water intensity. Lower material intensity (packaging)
Recycling system. Efficient waste disposal.
Land, green spaces
and biodiversity
Increased agricultural productivity. Manage
Livability Improved health. Higher education. Global access to
information and entertainment (Internet).
TransportationProvide collective (transit) and private mobility.

19. Conventional Worlds
■Conventional Development
scenario
•Situation left as it is.
•Solution led to market mechanisms.
•Little or no collective efforts.
•Limited success of birth control
policies.
•Generation of wealth, but unfair
distribution.
■Consequences
•Growth of inequalities and
environmental degradation.
•Potential instability and environmental
collapse.
1

20. Conventional Worlds
■Balanced Growth
•Legislation and policy intervention:
•Strengthen management systems.
•Ensure widespread use of better
technology.
•Provide greater social equity and
environment protection.
•Same patterns of production and
consumption.
•Notions of global governance.
■Consequences
•Less demographic growth and
environmental damage.
•May not be enough to curb major global
environmental issues.
•Socialism.

21. Barbarization
■Breakdown
•Neo-Malthusian perspective.
•Case of destructive anarchy.
•Governmental and social failures.
•“Mad Max” scenario.
■Consequences
•Environmental and social deterioration:
•Scarcity, violence, and massive
migration.
•Unchecked population growth.
•Economic collapse:
•Drastic fall in global population levels.
•Loss of institutions, productive
capacity, and technology.

23. Barbarization
■Fortress World
•Authoritarian “solution”.
•Conflicts between the rich and the poor:
•A minority of the elite in privileged
enclaves.
•Protect their way of life by forcibly
imposing limits and social controls on the
impoverished majority.
•Seizing control of critical natural resources
for exclusive use.
•Restricting access to information and
technology.
■Consequences
•Unchecked demographic growth.
•Social stratification.
•Instability of a “Fortress” system may push
the world into a “Breakdown” situation.

Great Transitions
■Eco-communalism
•Deep green utopian vision.
•Strong collective efforts towards
small-scale.
•Emphasis:
•Bio-regionalism.
•Localism and face-to-face
democracy.
•Small technology and economic
autarky.
■Consequences
•Population and economic scales
diminish.
•Environmental conditions improve
dramatically.
•Socialism/communism?

25. Great Transitions
■New Sustainability Paradigm
•Change the industrial civilization.
•Achieving sustainability at the global
level:
•Every activity most demonstrate
sustainability.
•More equitable global civilization rather
than to retreat into localism.
■Consequences
•Dramatic decrease of per capita
material flows:
•Through behavioral changes and
technology improvements.
•High-quality environment.
•Well-distributed welfare with economic
activities oriented towards services.

•The absolute bottom line.
•Will shape the fate of humanity in the 21
st
century.
•Period of strong demographic growth (demographic transition).
