- Purpose
- to become aware of the concept of sustainability
long term thinking - Learning Objectives. To understand/become aware
of - 1. The concept of sustainability with respect to
agriculture. - 2. The concept of sustainability with respect to
poor developing countries the global system - 3. The importance of long term thinking to avoid
possibly irreversible or very costly damage
loss of life
3Imperatives for Sustainable Systems
Economy (efficiency)
Individual/ Community (cohesion)
Environment (maintain/ enhance)
4Sustainability
- Normative standard/social goal
- Vision of the future
- Iroquois Confederation (7 generations)
- More inclusive/comprehensive view of economic
development/well-being - Whatever it takes to maintain the lives
livelihoods of people in the system
5Sustainable Agriculture, as an example
- An integrated system of plant animal
production practices having a site specific
application that will, over the long term
satisfy human food fiber needs enhance
environmental quality the natural resource
base upon which the agricultural economy depends
make the most efficient use of nonrenewable
resources and on-farm resources and integrate,
where appropriate, natural biological cycles
controls sustain the economic viability of farm
farm operation and enhance the quality of life
for farmers and society as a whole. - --The Food, Agriculture, Conservation, Trade
Act of 1990

resources cycling of waste ( life-sustaining
ecosystem) - 2. Human Capital people using knowledge/skills
to function - 3. Human-created Capital technology
productive facilities - 4. Social Capital networks of civic
institutions norms - 5. Cultural Capital myths/stories/visions
shared by people

15The Physics of Energy--Sustainability difficult
to maintain
- Energy the capacity for doing work
- The First Law of Thermodynamics the energy of
the universe remains constant (nothing is
destroyed also known as the Law of Conservation
of Matter Energy) - The Second Law of Thermodynamics entropy always
moves toward a maximum (energy moves from order
to disorder also known as the Law of Energy
Degradation)
16Entropy Energy Economics
- Gross vs. Net Energy
- Economic Reserves
- Exponential Growth
- Irreversibility
- Externalities
17Exponential Growth the 29th Day
- A French riddle for children illustrates another
aspect of exponential growth--the apparent
suddenness with which it approaches a fixed
limit. Suppose you own a pond on which a water
lily is growing. The lily plant doubles in size
each day. If the lily were allowed to grow
unchecked, it would completely cover the pond in
30 days, choking off other forms of life in the
water. For a long time the lily plant seems
small, so you decide not to worry about cutting
it back until it covers half the pond. On what
day will that be? On the 29th day, of course.
You have one day to save your pond. (D. Meadows
et al, 1972)

21Petroleum Fuel Estimates Historically Conservative
- Liquid-reserves revisions plus new discoveries
have kept ahead of consumption during 1990s - In 2003, confirmed liquid-resources in 1992 were
26 higher reserves than originally estimated - In 2003, confirmed gas resources discovered in
1992 were 36 greater resources than originally
estimated - Upward revisions to previous global reserves
estimates account for about 75 of all additions - Alexanders Gas Oil Connections, volume 8,

24Trends in Renewable Energy
- Wind, solar electricity costs
- reduced by 80-90 1980-2000
- Projected competitive 2005-2015
- Spain, Germany, Denmark provide over 20
electricity w/wind power - US provides 6 of total energy use w/renewable
energy 86 w/coal, oil, natural gas - Fossil fuels provide 75 of total energy
world-wide biomass provides about 13 - US per capita energy use growth rate falling from
7 in 1960s to 2 in 2000 - Union of Concerned Scientists, Clean Energy,

28Government Subsidies Matter to Many Energy
Sources
- Nuclear energy received 145 bil. in federal
subsidies 1943-1999 - Solary energy received 4.4 bil.
- Wind energy received 1.3 bil.
- Oil/gas projected to receive 11 bil. tax breaks

29How much will change in the future?
- In the long term 2020, . . . with fossil fuels
remaining the dominant source of energy. . . .,
our dependence on foreign sources of petroleum is
expected to increase and domestic natural gas
production and natural gas imports are expected
to grow significantly. - --Mary J. Hutzler, Department of Energy, March

Energy Information Administration, DOE, 2004.
31Agrarian Evolution Long Term Thinking
- Process of agricultural evolution has led to a
small percentage of large farms producing most of
sales in US - displaced farm labor has moved into non-ag sector
either in rural communities becoming more
diversified or moving to urban areas - Agricultural evolution in developing countries
more rapid, more disruptive, more destructive
harmful - 40-50 world population lives in urban slums
32Urban/environmental pressures increasing
- Low-income countries face water shortages, water
pollution, air pollution, minimal shelter
shortages, transportation stresses - Industrialization that is needed to uplift
economies will result in greater stresses on
environment natural resource base - 1.2-1.3 billion in absolute poverty
- 2/3 of world population live on less than 2/day
33Market Myopia?
- Biased w/short term perspective
- Discount rates favor present devalue long term
- Tend to under-value cultural/social costs
34Population Food Production
- Distribution is an issue
- AREA POPULATION FOOD
- ASIA 40 15
- AFRICA 10 5
- L. AMERICA 10 10
- EUROPE 25 45
- N. AMERICA 10 25
- OTHER 5 1
- NOTE While global distribution is an issue,
hunger exists in all parts of the world,
including the developed Western countries of
Europe and the US.
35World Hunger
- Each minute 20-35 humans die from hunger
malnutrition - 7-20 are children
- At minimum, equals a Hiroshima every 5 days
(140,000) - Chronic Hunger Malnutrition 14 of World
Population - 842 million people
- Lack of food and vatamin/mineral deficiencies
(iron, A, iodine, zinc) - Source World Food Day, various programs
36World Hunger (cont.)
- Point of comparison All Wars/conflicts of 20th
century claimed 130 mil-260 mil. - Hunger Deaths in Past 10 yrs 100-200 mil.
- 250,000 infants/small children may die each week
from diet-related, easily preventable diseases - Thousands more--diet-related blindness physical
mental retardation - Source World Food Day, various programs.

39World Hunger (cont.)
- World Hunger is NOT a food production problem
- Technology alone wont solve the problem
- Monoculture export agriculture may worsen problem
- Patent movement may worsen problem
- Economics--poverty--is the problem
- 1.2 billion people are below poverty level
- Distribution of resources is part of that
- Education is critical to the solution
40World Hunger (cont.)
- What causes poverty is complex and often varies
- Geography, weather, manmade conflicts, bad
policies, corruption - Economic development is the key
- Education is the foundation for economic
development - But . . .
- What is the carrying capacity of earth?
- Will the US allow development outside its plan?
- What pressures can we expect to worsen?
- Economic?
- Physical?
- Sociopolitical?
- Does population tend to stabilize as economy and
distribution improve?
41Poor Countries less efficient in energy use, thus
more wasteful polluting
- Developed (relatively wealthy) countries have
decreased CO2/GDP emissions 50 in past 30 years - Low-income countries produce about 5x more
emissions/GDP than rich countries - Example
- 1. US co2 emissions/person 24x India
- 2. US co2 emissions/GDP 1/3 of India levels
42Poor Countries access to clean air/water result
in severe health problems
- Over 1 billion people dont have access to safe
drinking water - 2 billion dont have adequate sanitation
- High rates of illness/disabilities
43Economic Development Argument
- Raise people out of poverty
- Lower fertility rates
- Increase use of cleaner, less resource-intensive
technologies - Often destructive to culture
- More sustainable?
- No guarantee that technology will keep up
- tendency for multinational corporate exploitation
- failures of empowerment often occur (especially
w/women), leading to dependency, injustice,
corruption, more exploitation, political
destabilization
44Income Distribution increasingly skewed
- Wealthiest 20 of world population accounts for
83 of world income - Poorest 20 account for 1.4 of world income
- Gap has more than doubled since 1960
- US Top 1 have as much after tax income as
bottom 100 million people (60)
45Arguments for failure of sustainable
environmental systems
- Rural poor living in fragile ecosystems
- Ineffective property rights/lack of enforcement
- Concentration of power/lack of accountability
(especially w/multinationals, non-democratic
governments) - Trade in waste/toxics
- Trade agreements that weaken environmental
protection
46Arguments for failure of sustainable
environmental systems (continued)
- Political power controlling lack of public
access - Government/corporate control of news media
- Market has a short term perspective
- Tax incentives distort environment/natural
resource management - Lack of leadershp in fostering ethical vision of
sustainability - Cultural dysfunction may lead to social problems
47Alternatives that may lead to sustainable global
situation
- Disaster(s) cause rapid reduction in population?
- Government intervention?
- incentives
- command control
- new world order
- Free Market may work?
- Multinationals take over?
