1960s? (Gateway 1)
2. What are the trends and challenges in the production of food
crops (Gateway 2)
3. How can the problem of food shortage be addressed? (Gateway

What’s up between DCs
and LDCs?

Developed countries (DCs)
vs
less developed countries (LDCs)
Economic indicators Social indicators
• Gross domestic product (GDP) per capital is
the total value of all final goods and
services produced by a country in a given
year divided by total population
• GDP per capita of DCs are higher
• Adult literacy rate measures the % of 15
years and above who can read and write
• Higher literacy rates lead to more
professionals who can contribute skills and
expertise in driving the economy
• More employment opportunities will result
in more jobs, leading to higher
income/standard of living
• Life expectancy refers to the average
number of years a person born in a country
is expected to live
• Influenced by war, disease, quality of
healthcare, water sanitation, food supply…

We have finished looking at the ‘how’
Let’s start looking at the ’why’

Gateway 1
Why do food consumption
patterns vary between DCs and
LDCs

Factors that cause variation in food consumption
patterns
(why do DCs & LCs vary)
economic Socio-
cultural
Political

1.
Economic
Disposable
income
Pricing

Disposable income
✘ The amount of income left after taxes
has been paid

Disposable income
✘ As economic conditions improved,
disposable income has increased,
enabling people to spend on more and
better quality food, leading to an
increase in food consumption.

Pricing
✘ People in LDCs are generally more
affected by food prices than people in
DCs as they have less disposable
income to afford increases in the
prices of staple food.
✘ People can be pushed into chronic
hunger and poverty as a result of any
food price crisis.

2.
Socio-
cultural
Food
preferences
Population
growth

Food preferences
✘ People’s concerns relating to health,
moral principles, income, religion and
the environment influence their choices
about the food they consume.

Food preferences- fast food
✘ Fast food is known for its convenience
and affordable pricing, thus more
people choose to dine there.
✘ Globalisation has made it possible for
fast food chains to be set up in many
LDCs
✘ In DCs, people are trying to move away
from fast food due to the harmful
effects

Food preferences- organic food
✘ Refers to food grown without the use of
artificial inputs, like chemical fertilisers
and growth hormones
✘ More people choose this due to the
perceived health benefits associated
with them
✘ Organic vs non-organic food

Population growth
✘ One of the key drivers in the increasing
demand for food worldwide.
✘ According to the FAO, the world’s
population is set to increase from 7
billion in 2012, to 10 billion in 2050.

Population growth
✘ Population growth is higher in LDCs
than DCs, as a result of family planning
and a need for farm labour in many
LDCs

3.
Political
Stability of
food supply
Food
safety

Stability of food supply
✘ A country has a stable food supply
when safe and nutritious food is
available to all people at all times
✘ Is affected by civil war and natural
disasters

Stability of food supply
✘ The stability of food supply in LDCs is
lower as food supplies are more prone
to disruptions in production and
supply due to lower political stability.
✘ The stability of food supply in LDCs is
lower as LDCs are less able to recover
normal food production capabilities
after a natural disaster.

Food safety
✘ Refers to a system that provides
guidelines, and ensures properly
handling, preparation, transportation
and storage of food that prevents
foodborne diseases
✘ The government plays an active role in
ensuring food safety, and to track
down/remove any contaminated food

Food safety
✘ Changes in food safety due to
outbreaks of foodborne diseases can
lead to sudden fluctuations in the
consumption of a particular kind of
food.

Health
Malnutrition
Starvation
Impact of
inadequate food
consumption

Malnutrition
✘ A condition in which the body does not
get sufficient nutrients to maintain
healthy tissues and organ functions,
and can lead to impaired physical
development and death.
✘ Can affect people in DCs, such as
people with eating disorders/ the
elderly who were eating too little
✘ LDCs more heavily affected
Impact of
inadequate food
consumption

Starvation: an extreme form of malnutrition
✘ The state of extreme hunger from a
severe lack of food, resulting in
permanently damaged organs and
death.
✘ More common in LDCs because of :
○ Greater number of poverty
○ Lack/absence of resources to
recover from natural disasters
○ Unstable political situations
Impact of
inadequate food
consumption

2.
Economic
Lower productivity
Diversion of
financial resources
to healthcare
Long term debt
due to food and
financial aid
Impact of
inadequate food
consumption

Lower productivity
✘ Inadequate food consumption can
lead to lower productivity as workers
fall sick more often as a result of
consuming imbalanced amounts of
nutrients, thereby leading to lower
income.
✘ For children, it will mean a loss of
school days, and subsequently a loss
of educational opportunities
Impact of
inadequate food
consumption

Diversion of financial resources to healthcare
✘ Public health expenditures increase
when the demand for health services
increase
✘ For LDCs, the higher spending on
healthcare means that limited financial
resources are diverted from other areas
like education, housing, agriculture etc
✘ This can slow down economic
development and growth
Impact of
inadequate food
consumption

Long term debt due to food and financial aid
✘ For the receiving country, especially
LDCs, the food supplied has been found
to be more expensive than if purchased
locally.
✘ This can increase national debts
Impact of
inadequate food
consumption

3.
Political
Social
unrest
Impact of
inadequate food
consumption

Social unrest
✘ Inadequate food consumption can lead
to social unrest as the lack of food may
cause people to protest and behave
violently to communicate their
unhappiness over the situation.
Impact of
inadequate food
consumption

4.
Social Scavenging
Impact of
inadequate food
consumption

Scavenging
✘ Refers to searching of food among
discarded wastes hence creating health
risks, as scavenged food contain high
levels of bacteria and chemicals.
✘ Carries risks because scavenged food
may contain high levels of bacteria, or
chemicals.
✘ May place people in dangerous/illegal
situations
Impact of
inadequate food
consumption

1.
Health
Obesity and
related
illinesses
Impact of
excessive food
consumption

Obesity and related illnesses
✘ The condition of having excessive fat
accumulation due to over-consumption
of nutrients to the extent that it may
have a negative impact on health
✘ More common in DCs than LDCs
Impact of
excessive food
consumption

2.
Economic
Lower productivity
Diversion of
financial resources
to healthcare
Impact of
excessive food
consumption

Lower productivity
✘ Excess food consumption leading to
obesity can lead to workers being
absent from work and students missing
school due to obesity-related health
issues, thereby leading to lower
productivity.
✘ May cost companies millions in
productivity and insurance costs
Impact of
excessive food
consumption

Diversion of financial resources to healthcare
✘ Public health expenditure can increase
as a result of treating obesity-related
health conditions, like cardiovascular
disease and diabetes.
✘ Governments have to channel more
funds to the healthcare system, reducing
funds for economic development.
Impact of
excessive food
consumption

3.
Social
Food
wastage
Dieting
Impact of
excessive food
consumption

Food wastage
✘ Excess food consumption can lead to
food wastage as countries with excess
food tends to be less careful in handling
food, leading to large amounts of food
being wasted.
✘ DCs face this more, where both food
producers and consumers throw away
food that is still edible
✘ Can put a lot of strain on landfills
Impact of
excessive food
consumption

Dieting
✘ Refers to the practice of regulating the
amount of food consumed in order to
maintain an ideal body weight.
✘ Can provide employment and value to
an economy as diet books,
medication/procedures to lose weight
can create jobs in the health sector
Impact of
excessive food
consumption
