The document discusses the transition from an era of food abundance to one of scarcity, exacerbated by factors such as population growth, climate change, and unsustainable agricultural practices. It highlights the increasing demand for grain, particularly soybeans, and the challenges of rising food prices and hunger. The document concludes with potential solutions to these issues, stressing the necessity for population stabilization, reduced meat consumption, and sustainable agricultural practices.

The New Geopolitics of Food Scarcity
By Lester R. Brown

2. CORN CROP TIME
• Wheat and rice :
world’s leading food grains
• Corn:
- Dominates the use of grain
in livestock and poultry feed
- Vulnerable to extreme heat
and drought

3. FROM AN ERA OF FOOD ABUNDANCE
TO AN ERA OF SCARCITY
• 1986 
• Until 2001 
• From 2002
to 2011

annual world carryover
stocks of grain: 74
days of consumption
annual world carryover
stocks of grain: 107
days of consumption
phasing out of the U.S.
cropland program
• Now  world living one year to the next
• Last half of the 20th century 
carryover stocks of grain
+ U.S. farm programs
• Soon  restricting exports to decrease domestic food price

4. EARLIER CIVILIZATIONS UNDERMINED BY FOOD SHORTAGES
• Sumerians:
rising salt levels in the soil
• Mayans:
deforestation and
losses of soil from erosion

5. SOURCES OF GRAIN DEMAND GROWTH
1. Population growth
Source: http://bixby.berkeley.edu/research/population/
2. Consumers moving up
the food chain

6. 3. Conversion of grain into fuel for cars
SOURCES OF GRAIN DEMAND GROWTH
Decline in stocks of grain
Rising food prices
+ Spread of hunger

7. CHALLENGES ON THE PRODUCTION FRONT
1. Soil erosion

8. CHALLENGES ON THE PRODUCTION FRONT
2. Growing water shortages
• Aquifers being depleted
• Irrigation wells starting to go dry
3. Plateauing of rice and wheat
yields in some agriculturally
advanced countries

9. 4. Earth’s rising temperature
CHALLENGES ON THE PRODUCTION FRONT
1 °C rise in temperature above the optimum 10% decline in grain yields

10. POPULATION GROWTH
• Consequences of the explosive population growth
(forests, fisheries, grasslands, aquifers, soils)
• Forests: overcutting
- growing demand for firewood, lumber, paper
- forests are shrinking
- Mauritania
• U.N. Demographic projections:
- world population 9.3 billion
in 2050
- enough water to grow food
for the 2.3 billion more people?

11. • Good news:
- Western and Eastern Europe
reached population stability
(970 million people)
- East Asia (Taiwan, China, North
and South Korea, Japan) very near
to population stability
- Indian Subcontinent
(India, Pakistan, Bangladesh)
- Sub-Saharan Africa (ex. Ethiopia)
• Bad news:
All of the population growth is in
developing countries:
Both 2.2 billion people in 2050
• Frank Notestein: “Three-stage demographic model”

12. SOLUTIONS:
• Smaller families
• Access to reproductive health care and family planning
services for every woman
• Two children per couple
• Stabilized world population
• Every country moving into “stage-three”

13. MOVING UP THE FOOD CHAIN
• Food habits depend on geographic location protein change
USA, Brazil, Argentina:
land-rich with grassland
Beef and mutton
Germany and China:
densely populated with lack of space
Pork
• During the years, meat consumption is changed:
- 1950: beef and pork dominated
- 1997: poultry overtook beef

14. Nowadays : pork is the world’s leading meat  China consumer #1

15. • During the years  greatest restructuring in seafood consumption
Japan:
too much land to produce rice
and it has to turn to seafood to
satisfy the demand of protein
China:
First one that turned to fish
farming  2010: 37 million tons

16. • The consumption of meat, milk, eggs and farmed fish indirectly pushes
the consumption of grain

18. Necessity to occupy an intermediate position in the food
chain: it will improve our life expectancy

19. EARTH’S CLIMATE: RISING TEMPERATURES
What makes the Earth’s temperatures rise?
The massive burning of fossil fuels is increasing the level of carbon
dioxid in the atmposhpere
http://climate.nasa.gov/

20. WHICH ARE THE CONSEQUENCES?
1. Agriculture: high temperatures interfere with pollination and
reduce photosynthesis of basic food crops
- corn pollination
- rice pollination
2. Increasing drought
3. Spreading of wildfires
4. Heat waves
1988 U.S.A.
2003 U.E.
2010 Russia
5. Melting mountain glaciers

21. MELTING MOUNTAIN GLACIERS
• China: the glaciers on the Tibetan Plateau feed
Yangtze river
Yellow river
• America
The Andes  Perù
The Rocky Mountains  Colorado River
• Greenland and Antarctic Rising sea level

22. BOOM OF PRODUCTION OF SOYBEAN
Reasons:
• Attainment of status
as valued grain (oil
and animal meal)
• Moving up in the food
chain (more meat)
• Growth of population
• Function as source for
biodiesel

26. PROBLEMS OWING TO INCREASING SOYBEAN YIELD
• Manifestations:
– More lands was occupied for soybean production
– Less lands was available for other grains
– The adverse effects of transformation of usage of land
• Starvation
• Acceleration of deforestation
• Loss of biodiversity
• Increase of carbon emission
• Classic case:
Brazil: land clearing plan in the Amazon Basin and the Cerrado

28. SOLUTIONS FOR PROBLEMS OF
MASS CONSUMPTION OF SOYBEAN
• Nexus in the problems:
Economic pressure originated from the increasing demands of soybean
at a rapid rate
• Cardinal principle of the solutions:
Curbing the growth in demand for soybean
• Concrete solutions:
– Stabilization of population worldwide
– Advocacy of downturn in meat consumption to affluent population
• Other ways?
– Scientific progress in increasing the soybean yield per acre
– Search for the substitute of soybean in animal meal
– ……

29. GLOBAL LAND RUSH
Rising food prices Restriction of food exportations “land grabs”
• Leading countries: Saudi Arabia, South Korea, China, India
• Countries selling or leasing lands: Sub-Saharan Africa, Southeast Asia

30. 1. Land acquisition is also water acquisition
Who benefits?
PROBLEMS:
2. Secret agreements  local farmers are not at the negotiating table
3. Increase in world’s hunger and human rights violations
4. Knowledge deficit
 problems in building infrastructures
 number of projects ≠ actual started productions
Source: http://www.bioecogeo.com/2014/10/28

31. • The World Bank working with the U.N. Food and Agriculture
Organization: set of principles governing land acquisitions
Developing countries need international support for local
village-level farmers
and NOT big corporations bringing large-scale, heavily
mechanized, capital- intensive agriculture

• Global power struggle for control of the earth’s land and
water resources

32. DEMAND SIDE
1. Stabilize world population
2. Eradicate poverty
3. Reduce excessive meat consumption
4. Reverse biofuels policies that encourage the use of food, land or
water that could be used to feed people
SUPPLY SIDE
1. Stabilize climate
2. Raise water productivity
3. Controlling soil erosion
‘’The challenge now is to move our civilization onto a sustainable path before climate
change spirals out of control and food shortages overwhelm our political system’’
