Title: Introduction to Sustainable Development


1
Introduction to Sustainable Development
  • Lecture A

2
Purpose of the Course
  • Introduce the Concept of Sustainability as the
    Foundation of Future Society
  • Provide a Foundation for Understanding and
    Implementing Sustainability Principles
  • Show the Importance of a Sustainable Community as
    the Key Concept
  • Indicate Methods for Implementing Sustainability
    in Various Social and Economic Sectors

3
Reasons for this Course
  • Humankind is profoundly affecting the Earth
  • Destruction of ecosystems and biodiversity
  • Global environmental problems greenhouse
    warming, ozone depletion, toxification, soil
    erosion, emissions
  • Mass movements of materials
  • Introduction of biological agents estrogen
    mimickers, genetically engineered products
  • Humankind does not understand or appreciate the
    role of ecosystems for our health and in our
    economy
  • Humanity may be crashing the critical planetary
    ecosystems
  • How do we change direction at this critical point
    in time? Globally? In Poland?

Proposed Solution -Briefly
  • Sustainable development or sustainability
  • Development that meets the needs of the present
    without compromising the ability of future
    generations to meet their own needs World
    Commission on Environment and Development, 1987
    Our Common Future (Brundtland Report)
  • Balancing environment, economy, and societys
    needs
  • Sustainability Clarified Satisfying lives for
    all within the means of naturenow and in the
    future. Redefining Progress, 2002,

  • Factor 4 and Factor 10
  • Carrying Capacity
  • Ecological Footprint
  • Ecological Rucksack
  • Adaptive Management
  • Ecological Economics
  • Environmental Ethics

The Twin Problems Population and Consumption
  • Human population has been growing exponentially
    since the beginning of the industrial revolution
    (1.7/year)
  • Industrial production has also been growing at an
    exponential rate (3.5/year 1970-2000)
  • World fertilizer consumption is doubling every 15
    years. Total use now is 15 times greater than
    the end of WWII.
  • In this century, consumption of energy and
    materials will increase by a Factor of 12
    (2000-2100) if growth in population continues at
    the same rates

Population Growth over Time
  • 1650 0.5 billion 0.3/year DT250 yrs
  • 1900 1.6 billion 0.5/year DT140 yrs
  • 1970 3.6 billion 2.1/year DT 34 yrs
  • Result Superexponential growth, the rate of
    increase is increasing
  • 1990 5.4 billion 1.7/year DT 42 yrs

Key Lesson about Growth Rates
  • Apparently small growth rates have massive
    consequences
  • World population growth rate is only 1.7
  • Buy means 78 million new people per year
  • World population doubled since 1960!
  • Why?

IPAT Formula
ImpactPopulation x Affluence x Technology
I P x A x T Impact
(throughput) of a population on the planets
sources and sinks equals the population times its
affluence times the damage done by the
technologies supporting the affluence.

Affecting IPAT Outcomes
  • Population (P) family planning, female
    literacy, social welfare, role of women, land
    tenure
  • Affluence (A)
  • Capital stock/person values, prices, full
    costing, what do we want?, What is enough?
  • Material throughput/capital stock product
    longevity, material choice, minimum materials
    design, recycling/reuse/recovery, scrap recovery
  • Technology (T)
  • Energy/material throughput End-use efficiency,
    conversion efficiency, distribution efficiency,
    system integration, process redesign
  • Environmental impact/Energy Benign sources,
    scale, siting, technical mitigation, offsets

21
Some Evidence of Real Problems
  • Humans are coopting 40 of terrestrial and 30 of
    aquatic Net Primary Production (NPP) (Vitousek et
    al 1986))
  • Humans are coopting 26 of all evapotranspiration
    and 54 of available water runoff, a net of about
    30 of all the solar powered hydrologic cycle
    (Postel 1997)
  • Humans are moving 2x more material than all
    natural forces combined (Schmidt-Bleek 1997)
  • Atmospheric CO2 has risen from 290 ppm (early
    1880s) to 315 ppm in 1958, 345 ppm in 1990, 369
    ppm in 2000
  • Falling grain production

What is Sustainable Development?
  • Sustainable development is development that meets
    the needs of the present without compromising the
    ability of future generations to meet their own
    needs World Commission on Environment and
    Development, 1987 Our Common Future (Brundtland
    Report)
  • Agenda 21 In order to meet the challenges of
    environment and development, States decided to
    engage in a new global partnership ...
    sustainable development should become a priority
    item on the agenda of the international community
    UN Conf on Env Dev, Rio de Janeiro, June 1992
  • ... is nondeclining human well-being over time
    David Pearce, Economics of Sustainable
    Development, 1994

24
More on Sustainable Development
  • A particular system that when considered in
    isolation has a positive balance in relation to
    its own costs and benefits (Ravetz 1992)
  • Improving the quality of life within the carrying
    capacity or supporting ecosystems (WCU 1991)
  • The use of energy and materials in an urban area
    in balance with what the region can supply
    continuously through natural processes such as
    photosynthesis, biological decomposition, and the
    biochemical processes which sustain life (Lyle
    1994)
  • Something is 'sustainable' if it has the capacity
    to continue. (Sustainable London)

25
Lester Brown (Worldwatch Institute)
  • Over the long term for sustainability
  • Species Extinction lt Species Evolution
  • Soil Erosion lt Soil Formation
  • Forest Destruction lt Forest Regeneration
  • Carbon Emissions lt Carbon Fixation
  • Fish Catches lt Regeneration Capacity of
    Fisheries
  • Human Births lt Human Deaths

26
Key Points
  • Sustainability is concerned with future
    generations, intergenerational justice,
    resources, environment
  • Three systems must be maintained in healthy a
    healthy relationship ecological, social, and
    economic
  • Natural systems hold the key to human
    sustainability

Paradigm Shifts
31
  • Social problems
  • erosion of the family
  • educational system quality
  • crime and prisoners
  • decaying cities
  • Economic problems
  • unequal distribution of wealth
  • shift of productivity income, workers to capital
    owners
  • technology driven creative destruction
  • Environmental problems
  • loss of natural capital rainforest
  • greenhouse warming and ozone depletion
  • loss of soil, over-fishing, over-grazing,
    over-foresting

What is the connection between...?
32
Thinking Sustainably Observe Nature
  • There is no such thing as waste
  • Live off current solar income
  • Respect and foster diversity

A key lesson from this course!
33
General Sustainability Principles
  • minimize resource consumption, use of
    non-renewables, pollution, toxics, waste
  • maximize efficiency, reuse, recycling, renewable
    resource use
  • foster conservation, understanding of natural
    systems functions, economic justice
  • focus on quality v. quantity, needs v. wants
  • redesign the economy and artifacts to mimic
    natural systems

34
Waste Pollution Inefficiency Lost
  • Positive Correlation environmentalism economic
    prosperity
  • Germany
  • environmental technologies
  • environmental policy economic policy
  • improved environmental quality improved
    competitiveness
  • Japan
  • 40 less energy in steel production than US, far
    less air pollution
  • defy conventional wisdom
  • Research Agency of Innovative Technology for the
    Earth international competitiveness

35
Perverse Economics
  • Environmental damage actually add to GNP
  • Depletion of natural resources adds to GNP ( tax
    credits!!)
  • The polluter hardly pays
  • Waste disposal is heavily subsidized
  • Maximum ROI drives corporate decisions
  • Discount rate maximizes todays
    consumption/depletion

36
Strong vs. Weak Sustainability
  • Refers to different schools of thought
  • Strong natural capital is irreplaceable
  • Weak natural capital is substitutable by
    manmade capital
  • More discussion when we cover economic concepts

37
Summary
  • Extraction of resource and environmental damage
    continuing and even accelerating
  • We are rapidly destroying adapted, diverse
    ecosystems crucial to both our economy and our
    survival
  • Growth as a basic assumption of the economic
    system is mathematically and physically
    impossible
  • Sustainability can help us change course to live
    within the constraints of nature with a high
    quality of life, to change our thinking.

The significant problems we face cannot be
solved at the same level of thinking we were at
when we created them. - Albert Einstein
