CHAPTER 12
The Production and
Distribution of Food
© 2011 Pearson Education, Inc.
Introduction to food production
• Half of the world’s people eat rice
• High in energy; low in vitamins and other nutrients
• Vitamin A deficiency: blindness, immune system
failure
• Affects 195 million children
• Iron deficiency: anemia and immune system failure
• Causes 100,000 maternal deaths/year
• Golden rice (GR2): genetically modified rice
• Added genes allow rice to synthesize beta carotene
(used to synthesize vitamin A) and iron

Frankenfoods
• The golden rice concept has not been welcomed
by all
• It is a genetically modified (GM) crop
• It contains genes from corn and beans
• Greenpeace has waged a campaign against
golden rice
• Frankenfoods: foods that contain foreign genes
• Created in the laboratory
• Genetic-engineering technology may be needed
to feed billions more, with better nutrition
• Decades of rapid population growth have left
millions dependent on imported food or food aid
© 2011 Pearson Education, Inc.
Successes
• Humans have done well at putting food on the table
• World food production doubled in the past 30 years
• Rising faster than the population
• The amount of food in developing countries has
increased
• World food trade is a major economic production in
many countries
• More people are overweight than are hungry
• But will it be possible to feed 10 billion?
• Reaching the MDG goal of halving the number of
hungry is in question
© 2011 Pearson Education, Inc.
Patterns of food production
• 12,000 years ago the Neolithic Revolution
introduced agriculture and animal husbandry
• Fostered development of civilization
• Major crops and animals were established in the first
1,000 years
• Food exchange and discovery (1450–1700)
• From the New World: potatoes, maize, beans,
squash, tomatoes, pineapples, cocoa
• From the Orient: rice
• From Europe: wheat, onions, sugarcane, animals
© 2011 Pearson Education, Inc.
Modern industrialized agriculture
• Until 150 years ago, most Americans lived and
worked on small farms
• Supplied a robust and growing nation
• Farmers used traditional approaches to pests and
erosion
• Crop rotation, multiple crops, animals wastes as
fertilizer
• People left the farm for jobs in cities and towns
• The Industrial Revolution in the mid-1800s
impacted farming

Traditional versus modern farming
© 2011 Pearson Education, Inc.
Transformation of traditional agriculture
• The Industrial Revolution profoundly changed
agriculture
• Three million U.S. farmers feed the nation
• Plus produce enough for export
• This revolution increased farming efficiency
•
•
•
•
Farm numbers went from 6.8 million to 2.1 million
Farms increased in size fourfold (to 449 acres)
Farm jobs account for 15% of the U.S. workforce
The U.S. has frequently produced surpluses
• Other industrialized nations have had this
revolution

Components of the agricultural
revolution
• Infrastructure: transformed agriculture
• Rural electrification, roads, university programs,
markets, transportation, loans, extension
programs
• Price and income support subsidies
• Subsidies favor corporate farms, not poor farmers
• Machinery: handles every need for working soil
• Seeding, irrigating, weeding, harvesting
• Tractors, combiners, handlers, mowers, toppers,
etc.
• Farmers can cultivate far more land
• Creates a dependency on fossil fuels
© 2011 Pearson Education, Inc.
More components of the revolution
• Land under cultivation: U.S. pastureland and
crops comprise one-third (987 million acres) of
the total land area
• Since 1960, increased yields and surpluses
reduced the need for land conversion
• Conservation Reserve Program: reimburses
farmers for retiring erosion-prone land and
planting it with trees or grasses
• More land will be used to grow corn for ethanol
• Globally, valuable and fragile forests and
wetlands are converted to cropland
© 2011 Pearson Education, Inc.
Components of the agricultural
revolution
• Fertilizers: increase yields
• One ton of fertilizer increases grain yields 15–20
tons
• Current use is higher than ever
• High demand is tied to high food prices
• Most increase is in China, India, Brazil
• Pesticides: control insect and plant pests
• But pests have become resistant to many pesticides
• Despite increased use, losses to pests remain
constant
• Pesticide use is decreasing due to health and
environmental effects
© 2011 Pearson Education, Inc.
More components of the revolution
• Irrigation: occurs on 18% of all cropland
• It produces 40% of all food
• Irrigation is still expanding but at a slower pace
• Problems include groundwater depletion,
salinization, and waterlogging
• High-yielding varieties of plants: plant geneticists
have developed new varieties of wheat, corn,
and rice
• Yields double or triple that of traditional varieties
• Photosynthetic product is diverted to seeds, not
stems, leaves, or roots
© 2011 Pearson Education, Inc.
The Green Revolution
• The Green Revolution: technologies that resulted
in remarkable increases in crop production
• In 1943, Norman Borlaug and others bred dwarf
hybrid wheat with a large head and thick stalk
• Mexico tripled wheat production
• Borlaug was awarded the Nobel Peace Prize in
1970
• Many other countries increased crop yields
• Grain production exceeded population growth
• The Green Revolution has done more than any
other single achievement to prevent hunger and
malnutrition

Panacea?
• High-yielding varieties are now used around the
world
• Has decreased deforestation in developing nations
• The Green Revolution is not a panacea for all
difficulties
• Grains do best on irrigated fields
• But water shortages are increasing
• Grains require fertilizer, pesticides, and energyusing mechanized labor
• It has not eradicate hunger or poverty
• People can’t afford to buy food
• There is no safety net
© 2011 Pearson Education, Inc.
Impacts of the Green Revolution
• Research now focuses on disease, pests, and
climatic stresses
• The early revolution helped Asia and Latin America
• Later years mainly helped Africa and the Middle
East
• Without a Green Revolution, yields in developing
nations would have been lower
• Would have led to higher food prices, more
cultivated land, increased hunger, and higher infant
mortality
• Sub-Saharan Africa still lags behind in agriculture
• Due to the dominance of subsistence agriculture

Subsistence agriculture
• Subsistence farming: developing world farmers
use labor-intensive traditional agricultural
methods
• Practiced on marginal land
• Described as the “silent giant” that feeds most of
the world’s poor
• Subsistence farmers live on small plots of land
• They raise food for their household
• They may sell a small cash crop
• They do not consider themselves poor
• Subsistence farming is practiced in regions with
rapid population growth
• But is best suited for low population densities
© 2011 Pearson Education, Inc.
Subsistence farming
© 2011 Pearson Education, Inc.
Problems in Africa
• 67% of people in sub-Saharan Africa depend on
agriculture for their livelihood
• They experience low yields, rapid population growth,
poverty, hunger, and high child mortality
• The World Bank’s World Development Report 2008
states that agriculture carries the potential for lifting
rural Africa out of poverty
• But most rural farmers lack fertilizer and seeds to
improve yields
• Government subsidies in Malawi have doubled
yields
© 2011 Pearson Education, Inc.
Alliance for a Green Revolution
• Money from wealthy countries allows subsistence
farmers to:
• Improve irrigation, soil health, and markets
• Grow enough food for their families
• Produce enough to encourage economic
development
• Subsistence agriculture works well in some areas
• Slash-and-burn agriculture: involves shifting
cultivation within tropical forests
• Cleared land supports a few years of crops
• Gradually shifts into agroforestry (tree plantations
with ground crops)

Animal farming and its consequences
• 25% of the world’s croplands feeds domestic
animals
• 70% of U.S. grain goes to animals
• The livestock economy: one of the most
important activities
• Four billion four-footed animals; 18 billion birds
• People enjoy eating meat and dairy products
• In the developed world, animals are raised in
confined animal feeding operations (CAFOs)
• In the developing world, animals are raised on
family farms or by subsistence farmers
© 2011 Pearson Education, Inc.
Cattle ranching in Australia
© 2011 Pearson Education, Inc.
CAFOs hurt the environment and
people
• Feeding crops to animals causes the same
problems as industrialized agriculture
• Manure in developing countries is used as fertilizer
• It is wasted in developed countries
• Manure overwhelms treatment systems and enters
water
• Fish kills, algal growth, and contamination with
pathogens
• Crowded animals allow diseases to spread
• Even to humans (e.g., avian flu)
• Salmonella causes $2.5 billion lost/year in the U.S.
• Heavy antibiotic use causes bacteria to become
resistant
© 2011 Pearson Education, Inc.
Rain forest crunched
• 58 million acres (23 million hectares) of rain forests
in Latin America have been converted to cattle
pasture
• Most land is held by few ranchers with huge
spreads
• Government policies encouraged colonization of
land to produce meat for domestic use
• Cattle production in the Amazon basin has
expanded
• It is now export driven
• Brazilian beef brings in $1.5 billion/year
© 2011 Pearson Education, Inc.
Climate change
• Deforestation and other land use changes in the
tropics release 1.6 billion tons/year of CO2
• Livestock belching and flatulence release 100
million tons of methane/year
• Methane is another greenhouse gas
• Anaerobic decomposition of manure releases 30
million tons of methane/year
• Methane released by livestock makes up 3% of all
gases causing global warming
© 2011 Pearson Education, Inc.
Good cow
• Although livestock contribute to the methane
problem, they enhance people’s diets and
quality of life
• Heifer Project International distributes livestock,
bee hives, fowl, and fish to families
• Local people oversee the projects
• Projects improve the environment
• Recipients must pass livestock offspring to others
• Animal farming is more sustainable in rural
farms in developing countries than CAFOs in
developed nations

Biofuels and food production
• Burning fossil fuels causes climate change
• Releases CO2 (a greenhouse gas)
• Biofuel: a renewable fuel made from ethanol and
oil derived from crops
• Can mitigate climate change
• No new CO2 is released
• With rising oil prices, biofuel prices are competitive
• Ethanol: made from corn (in the U.S.) and sugar
(Brazil)
• One-third of U.S. corn is devoted to ethanol
production
• Food prices have risen worldwide
© 2011 Pearson Education, Inc.
Consequences
• Critics say ethanol diverts corn from food production
• The U.S. produces 40% of the world’s corn and 55–
60% of the corn on the market
• Price increases take food away from children
• Does ethanol production decrease food?
• Wheat, rice, and soy prices have risen more than
corn
• Land previously planted in soybeans is planted in
corn
• Field corn is used to produce ethanol
• Only cornstarch is used for ethanol, leaving proteins,
vitamins, and fiber to produce food
© 2011 Pearson Education, Inc.
Factors contributing to high food costs
• Increased costs of oil for farm machinery and
fertilizer
• China and India are competing for oil
• Bad weather and poor harvests in Australia
• A major wheat exporter
• Rising demand for meat and animal products
from emerging economies
• 30% of increased prices from 2000 to 2007 is due
to biofuels
• Ethanol could be produced from grasses and
timber instead of corn
© 2011 Pearson Education, Inc.
Future prospects for reducing hunger
• Projections predict grain production to remain the
same
• Will slightly outpace population growth
• Also predict increased meat consumption in
developing countries
• Developing countries will not be able to meet
rising grain demands
•
•
•
•
Most suitable land is already farmed
Increases in grain yields are slowing down
Many countries can’t afford to pay for grain imports
Sub-Saharan Africa will continue to have hunger

Global picture
• There are only two ways to increase food
production:
• Increase crop yields
• Grow food crops on land now being used for
feedstock crops, biofuels, or cash crops
• Yields differ because of weather
• Soil, rainfall, and sunlight limit productivity
• It is impossible to predict how climate change
will affect rainfall patterns
• Developing countries could lose 334 million acres
of farmland due to tropical temperature increases
© 2011 Pearson Education, Inc.
Less meat and biofuels
• What is the possibility of switching from feed grain
and cash crops to food for people?
• Feed grain is a buffer against world hunger
• More people could eat lower on the food chain
• The trend is in the opposite direction
• Land could be converted from cash crops to food
• But land reform and a balance of trade are needed
• Biofuel production will increase
• By using marginal land and switching from other
crops
• Less corn will be available for animal feed and
exports
© 2011 Pearson Education, Inc.
A second Green Revolution
• A Doubly Green Revolution would
• Be more productive than the first Green Revolution
• Conserve natural resources and the environment
• It must repeat the first revolution’s successes
• Be equitable, sustainable, and environmentally
friendly
• This new revolution is possible through
biotechnology and genetic manipulation
© 2011 Pearson Education, Inc.
From Green Revolution to Gene
Revolution
• Genetic engineering incorporates desired traits into
plants and animals
• Producing transgenic (generically modified [GM])
organisms
• Genetic research of the Green Revolution used
genes that already existed or mutated in a species
• Genes can now be exchanged among plants,
animals, and bacteria
• This technology can help produce more food
• But there are concerns about its development and
use
© 2011 Pearson Education, Inc.
The promise
• The earliest and most common genetically altered
crops
• Pest-resistant cotton
• Herbicide-resistant corn and soybeans
• More recent crops include
• Sorghum resistant to a parasitic plant (witchweed)
• Insect-resistant corn, potatoes, cotton
• Rapidly growing trees and salmon
• Farmers have grown transgenic corn, soybeans,
and cotton
• 282 million acres were planted with bioengineered
crops in 2007

Objectives of agricultural biotechnology
• Stacked products: a crop containing two or more
biotech genes
• Traits directed toward different pests
• For example, pest resistance plus herbicide
tolerance
• Agricultural technology aims to:
• Incorporate disease and pest resistance in tropical
plants
• Increase tolerance to drought, salt, etc.
• Improve the nutritional quality of crops (e.g., golden
rice)
• Produce pharmaceutical products (“pharma crops”)

Environmental benefits of bioengineered
crops
• Reduced pesticide use
• Crops are already resistant to pests
• Less erosion
• No-till cropping
• Herbicide-resistant crops
• Less land brought into production
• Existing agricultural land produces more food
© 2011 Pearson Education, Inc.
Marker-assisted breeding
• New technologies improve crops without transgenic
traits
• Marker-assisted breeding: DNA sequencing locates
genes of desirable traits in crops or their wild
ancestors
• Plants with these traits are bred with modern crops
• High-calcium carrots; higher-yield pigeon peas
• DNA screening of seedlings for the desired genes
means plants don’t need to grow to maturity to see
if they were transformed
• This approach does not need special testing or
permits
• It is also cheaper, faster, and less controversial
© 2011 Pearson Education, Inc.
Problems of genetic engineering:
environmental concerns
• Pests may become resistant to the toxin in pestresistant transgenic crops
• The crop loses its advantage
• Resistance has been found in weeds that infest
fields
• Resistant weeds can spread rapidly
• Pollen from transgenic crops can spread to natural
areas
• Kills beneficial insects
• This occurred in monarch butterflies in the lab
• Genes can spread by pollen to ordinary plants
• Create “super” weeds
© 2011 Pearson Education, Inc.
Problems of genetic engineering:
safety issues
• Transgenic crops contain proteins from other
organisms
• This could trigger an allergic reaction in people
• Brazil nut genes incorporated in soybeans induced
an allergic reaction to people allergic to the nuts
• Antibiotic-resistant genes are put into organisms
• This could convey resistance to pathogens
• Antibiotics could become ineffective
• Plants could produce new substances in response
to foreign genes
• None of these concerns has become evident in the
field
© 2011 Pearson Education, Inc.
Pharma crops
• Pharmaceuticals are produced by engineering
genes for desirable products into crops
• The U.S. Department of Agriculture (USDA) has
given 200 permits for field tests
• Involving hormones, enzymes, drugs, etc.
• The Union of Concerned Scientists (UCS) asked
the USDA to stop outdoor production of these crops
• Pharma crops could contaminate other crops
• Corn that produces pig vaccine was almost used in
food
• So instead, produce pharmaceuticals with noncrop
plants
© 2011 Pearson Education, Inc.
Problems of genetic engineering:
access in the developing world
• Large agricultural-industrial firms developed early
genetically modified organisms
• Profit is their major motive
• Poor farmers can’t afford to buy the seeds
• Some noncommercial and donor-funded labs are
helping
• Research in other countries allows farmers access
to crops
• Genetically modified seeds are spreading through
“piracy”
• The UN FAO reports that benefits are still mostly
theoretical
• But millions have benefited from higher yields, etc.

Fear vs. acceptance
• Concerns and fear have generated controversy
over genetically modified food
• Protests are strongest in Europe
• Concerns are made worse by other scares (e.g.,
mad cow)
• Governments may use the controversy to prevent
importing cheaper food
• The U.S. is far less concerned
• 60% of food contains genetically modified
substances
• U.S. policy does not require mandatory labeling
© 2011 Pearson Education, Inc.
The policies
• In the U.S., the EPA, USDA, and FDA (Food and
Drug Administration) regulate genetically
modified food crops
• Conclusions of the National Research Council’s
report Genetically Modified Pest-Protected
Plants: Science and Regulation
• Transgenic crops have been adequately tested
• Agencies need to better coordinate and present
information to the public
• No evidence that these foods are unsafe
• Need more research on environmental and safety
issues
© 2011 Pearson Education, Inc.
Cartegena Protocol
• UN Convention on Biodiversity’s conference in
2000
• Dealt with trade in genetically modified organisms
• The Cartagena Protocol on Biosafety
• Was welcomed by governments, the private sector,
and environmental groups
• Covered how technologies should be regulated
• Critics of biotechnology wanted proof that
genetically modified organisms are safe
• Advocates wanted proof of their dangers before
they are denied access to overseas markets
© 2011 Pearson Education, Inc.
Stipulations of the Cartagena Protocol
• Countries can prevent entry of genetically
modified organisms
• But must base decisions on sound science
• The precautionary principle: if there are threats
of serious or irreversible damage, lack of scientific
certainty is not a reason for failing to take
measures to prevent damage
• Shipments of food made of genetically modified
organisms must be clearly labeled
• 147 countries (not the U.S.) have ratified the
protocol
© 2011 Pearson Education, Inc.
A regulatory framework for new
technology
• The public response to this regulatory framework in
the EU is negative; it is positive in the U.S.
• The EU lifted a ban on genetically modified foods
• But require clear labeling
• The trend is favorable toward adopting this
technology
• 23 countries currently grow biotech crops
• The future will include advances in biotech crops
• Will likely benefit developing countries
• “Responsible biotechnology is not the enemy;
starvation is”
© 2011 Pearson Education, Inc.
Food distribution and trade
• For centuries, the rule for food was self-sufficiency
• Climate, blight, and wars interrupted agriculture,
leading to famine and death
• The Industrial Revolution intensified trade
• Nations shipped foodstuffs around the world
• The need for self-sufficiency decreased
• Food became globalized
• World trade in agriculture: $1 trillion in 2008
© 2011 Pearson Education, Inc.
Patterns in food trade
• Some nations (U.S., Canada) produce more
than the people need
• Other nations (developing world) export special
crops
• Coffee, fruit, sugar, spices, palm oil, cocoa, nuts
• Trade helps the exporter
• Importers obtain out-of-season or specialty food
• Trade works only if the importing nation can pay
cash
• Japan imports $48 billion/year of food and feed
• But it exports $596 billion/year in manufactured
goods
© 2011 Pearson Education, Inc.
Grain on the move
• Grain: the most important foodstuff on the market
• Wheat, rice, corn, barley, rye, sorghum, oilseeds
(soybeans)
• In 1935, only western Europe imported grain
• Asia, Africa, Latin America were self-sufficient
• By 1950, North America became a major food
exporter
• The world’s breadbasket and meat market
• The U.S., Argentina, and Brazil export oilseeds
• Europe and China import them for animal feeds
© 2011 Pearson Education, Inc.
Increasing dependence on food imports
• Asia and Africa have become more dependent on
imports
• They also have increased population growth
• Much food is internally supplied
• But persistent dependence is ominous
• If developing countries double grain imports,
exporters have to increase production or decrease
use
• The world’s grain supply has never run out
• But in 2008 use exceeded production
• Enough grain was available by using carryover
stocks
• 2007–2008 became known as the global food crisis
© 2011 Pearson Education, Inc.
Production and use of world grains,
1998–2008
© 2011 Pearson Education, Inc.
The global food crisis
• Between 2006 and 2007, food prices roses 100%
• Triggered riots and emergency measures in many
countries
• Food supply could not keep up with demand
• Higher petroleum and fertilizer costs increase
production costs
• Diversion of corn and other crops to biofuels
• Demand for higher-quality diets (meat, dairy) in Asia
• Weather-related shortfalls in exporting nations
• Declining carryover stocks
© 2011 Pearson Education, Inc.
Future food prices
• Some factors of decreased food production are
temporary
• Better weather and technologies can increase yields
• The downturn in the economy reduced fuel prices
• Biofuels and the demand for better diets will not go
away
• The outlook for future food prices?
• Food prices will decline to new, higher levels
• Developed nations get higher prices
• But developing nations can’t afford to import food
• Increased undernourishment and malnutrition
© 2011 Pearson Education, Inc.
Food security
• Food security: assured access for every person to
enough nutritious food for an active and healthy life
• Three levels of responsibility for food security
• The family, the nation, the global community
• In a market economy, food flows in the direction of
economic demand
• Need is not considered
• A cash economy provides the opportunity to buy
food
• But not the food itself
• The next level may or may not buy food for a poor
person
© 2011 Pearson Education, Inc.
Responsibility for food security
© 2011 Pearson Education, Inc.
Family level
• The most important level of responsibility
• The goal: meet the nutritional needs of everyone
• Provide freedom from hunger and malnutrition
• Four options for obtaining food security
•
•
•
•
Buy the food
Raise the food
Gather it from natural ecosystems
Have the food provided by someone else
• The fourth option implies a safety net of policies
or programs to provide food security needs of all
in society
© 2011 Pearson Education, Inc.
National level
• Safety-net policies and programs
• Official policies: welfare measures (food stamps,
Supplemental Security Income program)
• Voluntary aid through hunger-relief programs
• Feeding America: food banks that feed 25 million
Americans
• Many working poor and elderly must choose
between paying bills and buying food
• Charity, Aid, Recovery, and Empowerment Act
(2003)
• Farmers, ranchers, etc. can deduct the cost of food
donated to agencies
© 2011 Pearson Education, Inc.
Policies in developing countries
• The goal at the national level: self-sufficiency in
food
• Enough food for everyone in the country
• To meet this goal, a nation can grow enough
food or buy it
• Policies must exist to eliminate chronic hunger
and malnutrition
• Just land distribution
• A functioning market economy
• Many nations must turn to the global community
for food aid and technical development
assistance
© 2011 Pearson Education, Inc.
Global level
• Food aid flows from rich, developed nations to poor
nations
• Developing nations import and pay for food
• The World Trade Organization (WTO) brings
together developed and developing nations for
negotiations and policy decisions
• Developed nations use tariffs (taxes on imports)
and subsidies to protect their agricultural sectors
• And call on developing nations to liberalize their
policies
© 2011 Pearson Education, Inc.
Subsidies hurt the developing nations
• In 2005 Haiti cut its rice tariff
• Imported U.S.-subsidized rice (“dumping”)
• By 2000, Haitian rice production was cut in half
• Thousands of rice farmers lost their livelihoods
• Haiti became the third largest importer of U.S. rice
• The U.S. pays $1 billion/year in rice subsidies
• The newest U.S. farm bill still subsidizes products
• The EU has high tariffs and subsidies ($41
billion/year)
© 2011 Pearson Education, Inc.
Other needs
• There are other initiatives to help poorer countries
become food self-sufficient
• Relieving the debt crisis
• Resolving the trade imbalance between developed
and developing nations
• Developing nations export raw materials (cash
crops, mineral ores, petroleum) cheaply
• They pay higher prices for imported products
• Using labor in developing countries is helping
• Even low wages help workers improve their lives
© 2011 Pearson Education, Inc.
Hunger, malnutrition, and famine
• The objective of the UN World Food Conference
in 1974 was to end hunger and malnutrition within
a decade
• The 2008 UN World Food Summit addressed the
food crisis that added 75 million to the 848 million
hungry
• The MDG’s more modest goal is to reduce hunger
by half in developing nations by 2015
• There is enough food to feed everyone
• Along with global markets
• So why is there still so much hunger and
malnutrition?
© 2011 Pearson Education, Inc.
Malnutrition vs. hunger
• Hunger: a lack of basic food for energy and
nutritional needs so the person cannot lead a
normal, healthy life
• Malnutrition: the lack of essential nutrients
• Amino acids, vitamins, minerals
• Undernourishment: the lack of food energy
(Calories)
• Overnourishment: even in developing countries
• One-third of Americans are clinically obese (> 30
lbs overweight)
• An Internet-based food pyramid tailors the food
groups and amounts to age and physical activity

Extent of hunger
• Accurate, reliable figures on hunger are
unavailable
• Governments do not document such figures
• Two-thirds of the undernourished (642 million) are
in Asia and the Pacific
• India, Bangladesh, Pakistan, China
• Sub-Saharan Africa: the highest percent of
undernourished
• One-third of the population is afflicted
• The effects of hunger and malnutrition are greatest
in children and women
• Seriously limits growth and intellectual development
© 2011 Pearson Education, Inc.
Consequences of hunger
• Sickness and death are companions of hunger
• Poor nutrition lowers resistance
• Diseases (measles, malaria, diarrhea) become
common
• 5.5 million children die each year in developing
nations
• Children rarely starve to death
• They are weak, underweight, and vulnerable to
disease
• People in rural areas suffer seasonal hunger until
the next harvest
• They are thin and spare from hard work and little
food
© 2011 Pearson Education, Inc.
Malnourished children
© 2011 Pearson Education, Inc.
Root cause of hunger
• The root cause of hunger is poverty
• Hungry and malnourished people can’t buy or grow
food
• 1.4 billion people live in absolute poverty
(income < $1.25/day)
• They are rural, illiterate; spend ½ their income on food
• They suffer discrimination due to race, tribe, religion
• One measure of progress of reducing hunger is the
proportion of children under 5 who are underweight
• Only a few countries have reached the MDG goal
• Eastern Asia, Latin America, the Caribbean, North
Africa
• There are still 140 million underweight children

Reducing poverty and hunger
• China, Indonesia, and Thailand reduced hunger
and poverty
• Oil exports, Green Revolution technology, rural
development, social infrastructure
• Voucher programs for seeds and fertilizer
• Societies must address the needs of the hungry
poor
• Public policies
• Countries and whole regions face food
emergencies
• International responsibility is most important
© 2011 Pearson Education, Inc.
Famine
• Famine: a severe shortage of food
• Accompanied by significant increase in deaths
• Signals that society is unwilling or unable to feed all
• Immediate causes: drought and conflict
• Drought caused famine in the Sahel (1968–1974;

peace process
• Helped change the political landscape of south

and wars
• Climate change is causing erratic weather and
warming
• 20 countries are in crisis and require external help
• Ethiopia: 11 million need help to prevent famine
• Drought, government ownership of all land
• Increased malnutrition and livestock deaths
• Somalia: the worst humanitarian disaster in the
world
• Three million (45%) need emergency food

Food aid
• Widespread, severe hunger and famine are being
prevented only because of external assistance
(food aid)
• The World Food Program (WFP) of the UN
coordinates global food aid
• The U.S., Japan, and the EU donate food
• Other countries conduct their own food aid
programs
• Food aid was cut in half between 1993 and 1996
• It is at its lowest levels in 30 years
• Food aid is given to countries all over the world
• Not just to areas with famine

When aid doesn’t help
• Efforts to end hunger have occurred for 50 years
• The U.S. and Canada are leaders in donating food
• Famines have been averted or moderated
• But using food aid to alleviate chronic hunger is
not good
• Free or very cheap foreign food hurts local farmers
• They stop producing food, hurting those who sell to
them
• The entire local economy deteriorates
• Donating food aggravates the conditions it tries to
alleviate
© 2011 Pearson Education, Inc.
When it does
• The WFP targets most food aid to emergency
situations
• Some aid goes to “development projects”
• The poor can concentrate on other activities
• The WFP makes 80% of its food purchases from
developing countries
• Local farmers get income
• Needy people are fed
• The U.S. Congress requires food aid from the U.S.
to be American-grown
© 2011 Pearson Education, Inc.
The future of food aid
• It will continue to be an international responsibility
• Buffers against famine
• Is part of local development aid
• Helps against malnutrition
• Food aid is not enough
• Economic arrangements between rich and poor
nations need to be restructured
• Development aid must foster food self-sufficiency
and sustainable interactions with the environment
© 2011 Pearson Education, Inc.
Closing thoughts on hunger
• In 1980, a Presidential Commission reported that the
U.S. has a moral obligation to respond to hunger
• Alleviating hunger is a matter of addressing poverty
• In a market economy, short-term profit crowds out longterm sustainable management of natural resources
• National self-interest in rich nations promotes subsidies
• Developing nations need enlightened, uncorrupt
leaders
• We do not need new science or technology to end
hunger
• Political and social action at all levels is needed
