Title: The REAL Farm Crisis
1The REAL Farm Crisis
- Feeding a World of 10 Billion People
2The Green Revolution
- The reality of Romantic Agriculture A
constant struggle to survive in terrible
conditions of great ignorance and constant,
grinding toil and poverty. - Not until the middle of the 20th century have
most humans been freed from the personal
necessity of daily food procurement.
3Our World Food SupplyTwo key problems
- To produce sufficient quantities of desired foods
to satisfy needs and to do it in environmentally
friendly and economically sustainable ways. - To distribute food equitably
4Our World Food Supply
- Global food production is about 4.7 billion
metric tons, 99 from the land. - Plants produced 93 of the human diet, mainly
from about 30 species, including 8 species of
grains that provide 66 of the worlds food
supply. - The 7 of food that is from animal products also
comes, indirectly, from plants.
5World Food Production

metric tonnes)

1992
7World Cereal Production and Yield Requirements
- Actual 1990 cereal production was 1,970 mmt.
Actual 2000 production, 1,840 mmt Total 2000
world consumption 1,871 mmt. - Projected demand 2025 is 4,000 mmt.
- All cereal yield currently about 2.5 to 2.9 (tons
per hectare). Will need to nearly double (to 4.5
t/ha) by 2025.
8Raising Yields on Existing Agricultural Lands
- Much of increased food supply will have to come
from existing cropland. - In many areas, increases in the 50 to 100 range
are still possible - India, Latin America, E.
Europe, former USSR. - In other areas increases will be much more
difficult - USA, China, W. Europe.
9World Cropland Used 1961-1992 (Thousand
Hectares)

1961
10Bringing New Lands into Production The
Remaining Frontiers
- No opportunity in Asia, Europe. In fact, in W.
Asia approx. 50 million ac. are under cultivation
that should not be. - Sub Saharan Africa and South America are only
places left, and these have severe problems to be
addressed. - Some marginal cropland in US, but cannot be
farmed without environmental damage.
11What Can We Expect From Biotechnology?
- Green Revolution resulted from accidental
increases in maximum genetic yield potential. - Recent yield increases not due to increases in
genetic yield potential, but due to increased
resistance to diseases and insects. - Existing transgenic crops also increase yield by
increased pest resistance. - Increasing maximum genetic yield potential may
be possible with GMOs.
12What Can We Expect From Biotechnology?
- Is it safe? Its tested by 3 government
agencies. It is probably safe within knowable
limits, say thousands of scientists. - Is it environmentally risky? No product is
without risk, but existing gmvs should have no
competitive advantage over any other plant in a
non-commercial environment. - Can we survive without it? In the US, yes. In
Africa, no.
13The Good Old Days They Were Terrible
- We were poisoning ourselves.
- Over the past 30 years, we owe a great debt of
gratitude to the environmental movement in the
industrialized nations. - The protection of air and water quality, of
wildlife, soils, control of hazardous waste is
taken for granted. - In almost every category, more progress has been
made than most activists are willing to admit -
apocalypse sells.
14A Moment on the Earthby Gregg Easterbrook,
Penguin, 1996
- 1. Ecological impulses must be grounded in logic,
not sentiment. - 2. In the Western world, the age of pollution is
nearly over. - 3. The West must resist its instant doomsday
thinking and shift to protecting the environment
in the Third World.
15- 4. People are superior to plants and animals in
the natural order. It is absurd for
environmental dogma to consider the human role in
nature to be bad. - 5. Nature is not ending, nor is human damage to
the environment unprecedented. - 6. Nature may have an upper limit on its
potential to foster life.
16Summary
- To produce the 1990 US harvest with 1940 yields
would have required an additional 460 million
acres of equivalent cropland. - Technology exists or is under development to feed
10 billion people in the World, if we are
allowed to use it. - World population is 6 billion now, will be 10
billion in 2050. - To feed the current population with organic
farming requires about 2 billion people to
volunteer to depart the earth.

18The Heidelberg Appeal1992 Earth Summit - Rio
- The greatest evils which stalk our Earth are
ignorance and oppression, and not science,
technology, and industry, whose instruments, when
adequately managed, are indispensable tools of a
future shaped by Humanity, by itself and for
itself, in overcoming major problems like
overpopulation, starvation, and worldwide
diseases.
19Agricultural scientists and policy makers have a
moral obligation to warn political, educational,
and religious leaders about the magnitude and
seriousness of the arable land, food, and
population problems that lie ahead. If we fail
to do so in a forthright manner, we will be
negligent in our duty and inadvertently will be
contributing to the pending chaos of incalculable
millions of deaths by starvation. The problem
will not vanish by itself, to continue to ignore
it will make a future solution more difficult to
achieve. Dr. Normal Borlaug, 1970 Nobel Peace
Prize winner, Father of the Green Revolution
The man responsible for saving the lives of more
people than any other person in the history
of the world.
