1. What are the indicators of development?
Economic
indicators
• GDP per capita
•
Total value of all goods and services produced by a country in a given
year divided by the total population.
•
Higher GDP per capita
indicate higher income.
•
The higher the GDP per capita, the more developed a country.
• Employment opportunity
•
More employment
opportunities will result in more jobs.
•
When people are
employed, they will have an income and can afford to buy more goods and
services.
•
There is higher employment opportunity in the developed
countries.
Social
Indicators
•
Adult literacy rate
•
Percentage of those aged 15 and above who can read and write.
•
Countries with high
literary rate have more professionals who can drive the country’s economy.
•
The higher the adult literacy rate, the more developed a country is.
•
Life expectancy
•
The average number of years a person is expected to live.
•
A country that is
more developed has higher level and higher quality of healthcare, water,
sanitation, food supply and living condition.
•
The more developed countries have higher life expectancy.
•
Examples of Developed countries: Australia, Japan,
South Korea, Singapore, USA
•
Examples
of Less Developed countries: Bangladesh, Brazil, Indonesia, Uganda
2.
What are the
indicators of food consumption?
·
Food consumption per capita (kg/capita/yr) is the average amount of food a person consumes per year.
·
DCs consume higher
amounts of meat and vegetables per capita than LDCs.
·
DCs consume higher amounts of food overall compared to LDCs.
·
Daily calorie intake (kilocalories) is the energy obtained from food consumed per person each day.
·
Average of 2,586 kilocalories required per day.
·
DCs have higher daily
calorie intake than LDCs.
·
Starchy staples as % of all calories
·
Staple food is starchy food that forms the main part of the diet.
·
Cereals which is a
staple food is high in starch, a form of carbohydrate, providing the human body
with energy.
·
Cereals consists of
grains such as wheat and rice
·
Non-staple food consist of meat, fruits and vegetables.
·
Meat e.g. beef,
chicken, fish are high in protein and fats.
·
Fruits and vegetables
are high in vitamins, minerals and fibre.
3.
How do food
consumption patterns vary between DCs and LDCs over time?
·
When a country
develops economically and its income per capita increases, the diet generally
changes from crop-based products to meat-based products.
·
People
in the USA consume higher amount of meat, eggs and fish.
·
Large
increase in the consumption of meat, eggs and fish in China due to increase in
wealth.
·
Cereal consumption in
China and India is higher than the USA as rice is a staple food in Asian
societies.
·
Cereals contribute to
50% of the global calorie intake.
·
In
Africa and parts of Asia, cereals make up as much as 70% of the people’s
calorie intake..
·
Lower
consumption of cereals in DCs – around 30% of calorie intake.
·
Consumption of
cereals per capita decline with higher income.
·
Crop-based
product is 40% of people’s diet in the LDCs but only 13% in DCs
·
As income increases,
rice is substituted with wheat to make bread and noodles e.g. in Brazil, China
and South Korea.
·
Increase in income is
linked with an increase in meat consumption.
·
In
LDCs, the demand for livestock (cows, pigs, sheep or chickens) has increased
since 1960s.
·
High consumption of
meat in DCs compared to LDCs but the rate of increase is smaller. People in the
DCs are consuming less red meat as this has been linked to health problems such
as obesity and heart diseases.
·
Larger increase in consumption of non-staple food from the LDCs due to
rising incomes.
·
Consumption of fruits and vegetables has increased for both DCs and
LDCs.
·
Mainly due to
increase in incomes in the LDCs.
·
Efforts of
international organizations such as the World Health Organization and the Food
and Agriculture Organization of the UN to promote its consumption. It is
believed that a significant amount of fruits and vegetables in a diet reduces
the risk of diseases such as heart disease, cancer and diabetes.
4.
Why do food
consumption patterns vary between DCs and LDCs?
Economic
factors affecting food consumption
v Disposable income
v Food pricing
- Disposable
income is the income left to an individual after taxes
have been paid.
- Disposable
income is increasing for DCs and LDCs.
- Disposable income is higher in
DCs.
- People
have higher purchasing power with higher disposable income.
- People consume more meat and
less cereals when income increases.
- Higher
consumption of more organic food and olive oil in DCs as they can afford
food with more health benefits.
- People in LDCs are more affected
by food prices than the people in DCs as their disposable income is
lesser.
- Food
crisis between 2006 and 2008 cause 100 million more people worldwide into
chronic hunger and poverty. Many people in the LDCs cannot afford the
staple food due to the sharp increase in food prices.
Socio-cultural factors affecting food
consumption
v Religious beliefs
v Food preferences
v Migration
v Population growth
v Changing diets
- Religious beliefs can
influence a person’s choice of food as well as how food is prepared.
- Muslims can only consume food
that is halal.
- Fast food has
been well received by people due to convenience
and affordable prices.
- Globalisation
made it possible for fast food chains to set up restaurants in many LDCs
such as India.
- Many
people choose to patronize these outlets rather than local food stalls
due to hectic schedules and rising
incomes.
·
People are now trying to move away from eating too much fast food as
they become increasingly aware of their harmful effects on human health.
·
Food preferences in DCs are influenced by health concerns such as the use of pesticides.
- More
people in the DCs choose organic
food due to the perceived health benefits associated with them.
- Migrants
introduce new food to places and drive the demand for new food
preference.
- Migrants
may adopt the food of the locals as they are exposed to local cuisine.
- Migrants introduce new cuisines
to people in their new country e.g. curry
restaurants in UK
- Increasing
demand for food due to increased
world population
- Population growth rates are
higher in the LDCs than DCs – therefore increasing demand
for food is greater in LDCs
- The diets of people in DCs and LDCs
will continue to change especially in terms of meat and dairy products.
- Due to globalization and
migration, diets in DCs will increase in variety.
- Traditional
rice eating societies are consuming increasing amounts of wheat as
ingredient in bread, cakes and pastry.
Political
factors affecting food consumption
A
country has a stable food supply when safe and nutritious food is available to
all people at all times.
- Government may take actions to
increase food supply or food imports to ensure the
availability of safe and nutritious food to the people.
- Food production can be increased
by improving technology to increase yields and opening up new areas for agriculture.
- LDCs
lack access to technology or finances to implement it on a large scale.
- DCs
have greater access to technology for food production to ensure food
stability.
- Civil war can affect food
stability. In Libya in April 2011, where cities and areas
with heavy fighting reported food and water shortages and safety concerns
restricted people from venturing out to buy food.
·
The
government ensure food safety by
setting food safety standards and ensuring the standards are met.
·
They
are also responsible for tracking down contaminated foods that cause outbreaks
of foodborne diseases and remove these foods from the shelves.
·
Seafood
imports from Japan to Singapore were restricted for many months after the
nuclear contamination due to the earthquake in Japan 2011.
·
Threats
to food safety may come from outbreaks of foodborne diseases e.g. “Mad Cow
Disease” outbreak in Europe in the late 1990s and in USA and Canada in 2005.
·
The
outbreak has led to a decrease in the consumption of beef because humans could
contract the disease by eating meat from an infected cow.
·
The
decrease in demand for beef led to a decline in the import of beef.
·
Decline
in beef consumption in the European Union after outbreaks in 1988, 1996 and
2000.
5.
What are the impacts
of inadequate food consumption on individuals and countries?
v Impact on health
v Economic impact
v Political impact
v Social impact
Impact
on Health due to inadequate food consumption
Malnutrition
– the body does not get a balanced amount of nutrients to maintain healthy
tissues and organ function.
·
Inadequate
nutrients will cause higher mortality rate and risk of adult chronic disease.
Ill-health
·
Lack of Vitamin A found in eggs,
cheese, meat, carrot etc can lead to visual
impairment and blindness. Children affected will miss attending normal school.
With lower educational opportunities, children will have lower earning power in
the future.
·
Lack
of Vitamin A also reduces the body’s ability to fight off common childhood
infection such as diarrhoeal diseases and measles.
·
Lack of Calcium found in milk,
cheese, green leafy vegetables and soya bean can lead to osteoporosis which is
the weakening of the bones.
·
People
with osteoporosis are more prone to fractures and this will cause loss of work
days and productivity.
·
Vitamin
D obtained by sufficient exposure to sun help the body to absorb calcium
Starvation
is
the state of extreme hunger from a severe lack of food.
·
The
body becomes skeletally thin and the organs become permanently damaged and may
lead to death.
Economic Impact of inadequate food
consumption
·
Inadequate nutrients
consumed lead to low energy level and more sickness which will lead to
lower productivity and lower income due to inability to work as productively as
before.
·
Economy of the
country adversely affected when there is low productivity. This lead to higher
public health expenditure.
- Food aid and
economic aid can cause long term debts
- Financial
resources are diverted to health care because more people are falling
sick.
Political Impact of
inadequate food consumption (social unrest)
- Inadequate food
supply leads to inadequate food consumption. People become malnourished,
starve or even die.
- Such conditions
can cause social unrest. In
2010, people in Mozambique protested against high wheat prices.
Social Impact of
inadequate food consumption (survival responses e.g. scavenging)
- Some people turn
to scavenging to prevent starvation
- Scavenging
carries health risks because scavenged
food contain high levels of bacteria or chemicals
- Scavenging also
place people in dangerous or illegal situations in search of food and they
are perceived as a nuisance to the public.
- e.g. child
scavengers of “Smokey Mountain” in Manila
6. Impact of excess
food consumption on individuals and countries:
Health Impact due to
excess foos consumption
- Obesity is the condition of being
overweight due to excessive consumption of nutrients
which is stored as body fats.
- Obesity
can lead to health problems such as
high blood pressure, coronary heart disease, diabetes and certain cancers.
Economic Impact of
excess food consumption (lower productivity)
·
When
people fall sick, there will be lower
productivity as there will be loss of work days.
·
It
can also cause lower income due to inability to work as productively as before.
·
Money
is redirected to public health expenditure reducing funds for developing the
economy.
Social issues of
excess food consumption ( food wastage and dieting)
·
Food
wastage – every year, consumers in DCs
waste almost as much food as the entire amount of food available in Sub-Saharan
Africa for local consumption.
·
Dieting
is the practice of regulating the amount of food consumed to maintain an ideal
weight.
·
Physical
exercise is often practiced in combination with diet.
·
Dieting
provides employment and value to an economy e.g. weight loss industry including
diet books, medication and medical procedures for losing weight.
·
However inappropriate
dieting may lead to depression and dieting-related physical illness such as
iron-deficiency anaemia.
7. How has the
production of crops changed since 1960s?
·
Need
to increase global food production to meet the rising population
·
Global
food production must increase 75% from 2000 to 2050 to meet the needs of
increased population which is expected to reach 10 billion in 2050.
8. What factors
affect the intensity of food production and supply?
Food supply chain
(linkages between consumers, producers and distributors)
·
Food producers are farmers and
ranchers involved in producing food. The food is processed and packaged by
manufacturers of food products which are then shipped to distributors.
·
Distributors ensure that the food
produced reaches the food retail outlets who sell them to the consumers.
·
Consumers refer to the people
who consume the food.
Trend in production
of food crops (rice and wheat) from 1960s
- Since the 1960s, production of rice, wheat
and genetically modified food has increased.
- Intensification
refers to the increase in the productivity of the land through an increase
in the total crop yield.
- Total
crop yield is the total
amount of crop obtained from an area of farmland.
- World
production of rice rose from 535.5 million tonnes in1970 to 1119.2 million
tonnes in 2010.
- The
global average crop yield of rice was 4.3 tonnes per hectare in 2010
compared to 2.4 tonnes per hectare in 1970.
- Due to rapid population growth
and increase in demand for food, countries have intensified food
production to meet the demand.
- World
production of rice rose from 535.5 million tonnes in1970 to 1119.2 million
tonnes in 2010.
- The
global average crop yield of rice was 4.3 tonnes per hectare in 2010 compared
to 2.4 tonnes per hectare in 1970.
- Increased production of
genetically modified food crops
Genetically modified crops are crops with genes that have been altered
to make them more resistant to diseases and to make them grow faster, thereby
increasing crop yield and productivity.
Blue tomatoes have
been genetically modified to produce high levels of anthocyanin, a pigment that
produces blue or purple colour.
- Between
1996 and 2011, the total land area used to grow GM crops increased from
17,000 km² to 1600000 km². By 2011, over 105 of the world’s crops were
genetically modified.
- Most
of these GM crops are grown in North America, but some LDCs are rapidly
increasing their production of GM food.
9. What are the factors
affecting the intensity of food production and supply?
v Physical factors
v Social factors
v Economic factors
v Political factors
v Technological factors
Physical
– Climate
- Temperatures and amount of
rainfall affect the growth of crops.
- Crops
such as pea, broccoli and strawberry require cooler climates. Other such
as soya bean and tomato require warmer climates.
- Plants
such as maize require more water than soya bean.
- In the tropics, the long growing
season enable farmers to have 2 to 3 harvests in a year.
- In
places with winter, food production can only occur during the warm season
where temperature and rainfall is suitable for growing crops.
Physical - Soils and Drainage
· Fertile soils contain minerals essential for plant growth.
Crop yield is higher in areas with fertile soil.
· Fertile soil combined
with flat terrain and large water supply in the Mekong Delta of Vietnam results
in very high production of rice.
· The clayey soil
allows water to be retained to grow rice.
· Growing of oats require sandy soil which is well drained.
Physical
– Relief
· The rain is more likely to remove the topsoil on steep
slopes.
The topsoil is rich in nutrients.
· Terracing – cutting of steps into a hillside to create flat land for
cultivation.
· However sloping land
is suitable for the growing of crops such as grapes, tea and coffee which needs
well-drained soil.
· Temperatures decrease with increasing altitude.
· The cooler
temperatures of mountainous areas may be suitable for growing certain cool
climate crops.
Social
- Land tenure
· Land tenure is the system
by which agricultural land is occupied.
· Most farmers in the LDCs are too poor to purchase their
own farmland. So they rent their land and pay a sum of money or a portion of
their harvest to landowners.
· This reduces
motivation to maximize production and led to low productivity. With lower
income, the farmers are not able to purchase equipment and supplies to improve
farming.
· Land fragmentation is the division of land into many
smaller plots over many successive generations of farmers.
· It is common inheritance
practice for the farmer to divide his land amongst his many children.
· Small plots of land
mean lower total output. Small plots
make it unprofitable to use machines to increase output.
· e.g. Tivland, Nigeria – due to land fragmentation, sizes of farms are
smaller and farmers are unable to produce sufficient yield.
Economic
-purpose of farming
Economic - demand
- The tastes and preferences of
consumers dictate what how much the producers grow.
- China
used to be self-sufficient in maize production and an exporter of maize as
well. However in recent years due to the increased demand for meat and
dairy products, more maize is needed to feed livestock. Together with
rising population, China has started importing maize to meet the
increasing demand. USA has increased their production of maize to be
exported to China.
Economic
–Trade
· Global trade has expanded and diversified. This is due to
improvements in the method of preservation, processing and packaging, advances
in rapid transport and handling, and changes in consumer tastes.
· Increasing amounts of land are used to grow crops for
export such as cut flowers, soya bean and coffee.
· In Sudan land is
being farmed for the production of animal feed instead of staple crops such as
sorghum.
· Free trade allows
goods and services from abroad to compete with domestic goods and services.
Economic
- Agri-business
· Companies are involved in most stages of the food supply
chain, including farming, processing and retailing.
· Large food companies
able to withstand the impact of changes in the environment, e.g. flooding,
compared to small-scale farmers.
· Agribusinesses are
able to invest in technology to
increase food production including research to produce crop with greater yield.
· As they have a
worldwide network of different farming, distribution and processing centres,
they have greater control over crop
production. Their production costs are reduced and hence the retail cost of
food may be kept low.
Political
– Agricultural policy
·
When
the government of Japan introduced policies aimed at reducing the production of
rice in the 1970s, rice production grew at a slower rate.
·
The
Acreage Reduction policy was introduced to keep the price of rice high by
reducing supply.
Political
– Food policy
·
Refers
to policy pertaining to how food is produced, processed, distributed and
purchased.
·
Also
involves health and safety and food labeling.
·
Food stockpiling
involves the storage of food for anticipated shortage.
·
Diversifying the
source of food supply
to buffer against food shortage and price fluctuation by over-relying on a few
countries.
Political
– ASEAN
·
In
Oct 2011, ASEAN signed an agreement with China, Japan and South Korea. During times of disaster, rice reserves
from the big rice producers will be used to supply rice to countries that have
signed the agreement.
·
Thailand
started a programme in 2012 for other ASEAN nations to intensify rice
production in the region. Thailand worked with neighbouring countries such as
Cambodia to increase their efficiency in rice production.
Political
– Common Agricultural Policy (CAP) of the EU
CAP came into force
in 1962 to:
·
Encourage better
agricultural productivity
·
Ensure that consumers
have a stable and affordable supply of food
·
Encourage sustainable
farming practices
CAP has helped 14
million farmers in the EU to increase productivity in the following ways:
·
Farmers receive
assistance in restructuring their farms to make them more productive
·
Subsidies are provided
for agricultural produce. However the cost of providing subsidies makes food more
expensive in the EU and is a heavy financial burden for countries that do not
have large agricultural industries.
·
Use
of import taxes on food products that
are brought in from outside the region. This helps to sustain demand for
local produce and ensures that farmers are not forced to stop farming due to a
lack of demand.
Success of CAP:
·
Improved
farm efficiency and food production e.g. wheat yields in EU original six member
states has increased from 3 tonnes per hectare in 1962 to 7 tonnes per hectare
in 2008
Technological advances – Green Revolution [ use of technology to
increase food production]
•
Use of high-yielding varieties
•
Use of chemical fertilizers and pesticides
•
Improved irrigation
•
Mechanization
Green Revolution -
Use of High Yielding Varieties
· HYVs are improved strains of crops such as rice, wheat
and other cereals that have an increased growth rate and an increased
resistance against crop diseases and pests.
· They need more water
and nutrients to sustain their growth.
· With a shorter
growing season, there can be more harvests a year.
· “Wonder Rice” has a
growing season of 100 days compared to the 120
days of non-HYVs.
· 70% of rice and wheat
grown in India were HYVs by 1990.
· Green revolution
helped to increase the production of wheat and rice in India.
o Total wheat
production has almost multiplied 4 times that of 1970 by 2010
o Total rice production has multiplied by two times that of 1970 by 2010
Green Revolution - Use of Fertilizers
· Chemical fertilisers replenish the nutrients in the soil
and increase yield.
· HYV requires more fertilizers
· Organic fertilizer
such as manure is slow releasing and helps to retain soil moisture.
· Chemical fertilizers
provide specific quantities of a nutrient such as nitrogen and potassium but are easily removed by water
percolating through the soil.
Green
Revolution - Use of Pesticides and Herbicides
·
Pesticides used to kill insects
and small animals that destroy crops.
·
Herbicides used to kill weed
and other undesirable pants that compete with crops for resources.
·
With
the removal of pests, the crop is protected which in turn would increase the crop yield.
Green
Revolution – Irrigation
· Irrigation is the artificial
way of supplying water to the land
· Land which used to be too dry for farming can now be
cultivated. So there is an increase in arable land.
· In the North African
country of Libya, the Great Man-made River made it possible to grow crops in
the Sahara Desert
· Extensive irrigation project consists of a network of
underground pipes, canals, wells, reservoirs and tunnels that drew water from
underground aquifers.
· Methods of irrigation:
o Centre-pivot
irrigation: a sprinkler is rotated,
automatically irrigating a circular area
o Mechanical irrigation-move:
a line of connected sprinklers travels across a field automatically using a
machine
o Flood irrigation : irrigation water delivered to a whole
surface
Green
Revolution – Mechanisation
· Farmers use machinery to perform tasks which they would
otherwise have to do manually
· Machines speed up
processes involved in preparing the land, tending to cops and harvesting.
· A combine harvester helps to harvest grain crops and reduced reliance on
labour.
Genetically
Modified Food
·
Crops which had their
genes altered to give them desirable qualities such as resistance to extreme
weather conditions or diseases.
·
e.g.
Golden Rice which has been infused with Vitamin A to prevent blindness.
·
Bt corn has a gene
from a naturally occurring soil bacterium known as Bacilllus thuringinensis
(Bt) This is a natural pesticide which protects the crops and reduces the risk
of it being damaged by pests.
HYV crops are cross
breed and GM crops involve alteration of genes.
Both HYV and GM crops have the benefits of shorter growing season, pest
resistant. GM crops have additional health benefits. Examples of HYV crops are
Super Rice, Wonder Rice and FlavrSavr Tomato. Examples of GM crops are Golden
Rice, Bt-cotton and Bt-corn.
10. What are the
effects of continuing intensification of food production?
Waterlogging
·
When
too much water seeps into the soil, the roots are deprived of air and
nutrients, causing them to die.
Salinisation
·
Water
added to the soil during irrigation evaporates and salt is left behind in the
soil.
·
Dissolved
salts from the groundwater reach the top soil when there is no proper drainage
of excess water.
·
Concentration
of salts may be too high for crops to grow well.
·
Salinisation
occurs in the Murray-Darling Basin in
Victoria Australia.
Eutrophication
·
Chemical fertilizers can be washed into
streams and river. The excess nutrients in water lead to algae bloom, causing eutrophication.
·
The
algae blocks sunlight from reaching
aquatic plants and eventually fishes that feed on them die as well.
·
Decomposition
of aquatic plants and animals depletes
the oxygen in the water.
·
Measure
taken to reverse the trends of eutrophication:
o
Control
measures aimed at preventing chemical fertilisers from reaching water bodies.
o
Raise
awareness of eutrophication through public awareness campaigns, school
environmental education programs and targeted outreach within the communities.
11. What are the consequences of development
of GM food crops?
Benefits
Increased
income for farmers
· GM crops that are
pest-resistant help farmers to save money on the cost of pesticides and on the
labour needed to administer the treatment.
· Higher output from GM
crops allows farmers to earn higher income.
· e.g. Bt-cotton which
has increased farmers’ income in India by US$12.6 billion from 2002 to 2011.
Nutritional
Benefits for Consumers
· Certain crops are genetically
modified to have higher nutritional value.
· Golden Rice has
higher levels of Vitamin A to prevent blindness.
Decreased
environmental pollution
· GM crops which are
resistant to insects and pests do not require insecticides and pesticides.
· This reduces the
release of chemicals into the environment that could lead to pollution.
Threats of GM Food
Dominance of agribusiness
· GM crops are
expensive and requires high capital investment which is affordable only to big
companies and DCs
· Small-scale farmers
and LDCs cannot afford the GM seeds.
· Widen the gap between the wealthy and poor farmers.
Human
health risk
· Growing concern that
incorporating foreign genes into plants may have adverse effect on human health
such as allergic reactions.
· e.g. introduction of
a gene from Brazil nuts into soya bean created allergic reaction in individuals
who are allergic to nuts
Genetic
pollution resulting in loss of biodiversity
· If the resistance of
GM food crop is transferred to wild plants, it can have negative impacts on
insects and other animals which feed on them leading to a loss in biodiversity.
· e.g. Monarch
butterflies died feeding on milkweed dusted with pollen from Bt-corn
12. Why do food
shortages still occur?
v Physical factors- climate change, pests
v Political factors- civil strife, poor governance
v Economic factors- demand from emerging economies, food
policy, soaring cost of fertilisers and transport, conversion of farmland to
industrial crop production
v Social factors- lack of accessibility, inadequate
logistics of food distribution and storage, rapid population growth
Physical
factor - Extreme weather
·
Droughts, cold winters,
heat waves and tropical cyclones may cause crop
damage or make it difficult to grow crops leading to food shortage.
·
Cyclone Yasi destroyed the
crops when it hit Australia in 2011.
Physical
factor - Climate change
- Existing farmland may become unsuitable
for farming.
- Climate change may lengthen the growing season
in other areas.
- Tropical cyclones lead to flooding of
farmland which destroys crops. Droughts reduce water supply needed for
crops to grow properly.
- Disappearance of glaciers reduce water
supply to rivers and affect farm productivity.
Physical
factor - pests
- Pests destroy food crops and contribute
to food shortage.
- Liberia had to declare a state of
emergency in 2009 when a new species of caterpillars devoured all plants
and food crops in their path, threatening food security in Liberia.
Political
factor – Civil strife
·
This
occurs when a country faces major internal conflicts such as riots, unrest or
civil war.
- Disputes
occur over the control of resources that affect food production such as
water and land.
- Food
production is hindered if resources are destroyed.
- In
2011, a civil strife in Syria disrupted agriculture and drastically
reduced farmers’ access to fertiliser and seeds.
- All
these caused food prices to rise and prevented people from having access
to food.
Political
factor - poor governance
·
Corruption,
policy errors and inability to implement policy can cause food shortages.
·
Governments
can threaten food security when they prioritise other developmental needs over
food security.
·
e.g.
Madhya Pradesh, India - 40,000 villagers
were deprived of land for farming due to development of a steel plant, mining
and port. The villagers lost the means to produce their own food and were left
with extremely limited income to buy food.
Economic
factor – demand from emerging economies
- Demand
for meat and dairy products from emerging economies like Brazil, Russia,
China and India (BRIC) has increased.
- This
is caused by a growing middle class with more purchasing power and
changing food preference.
- Increases
in food production is unable to cope with rapid increase in demand.
- Poorer
countries cannot afford to pay the same prices for food that richer
countries can.
Economic factor - food policy
·
Government must
ensure food security by controlling or influencing food prices and food supply.
·
Stockpiling is the
setting aside and storage of food to ensure food security during emergencies.
·
e.g. Algeria bought 800000 tonnes of wheat to
add to its stockpile.
·
Food
subsidies refer to money paid by a government or organization to make food more
affordable to consumers.
·
Food subsidies in the form of cash,
food vouchers or tax deductions can be given to elderly or people with low
income.
·
e.g.
food stamps distributed in the State of Massachusetts to citizens with low
income.
·
Countries that are
too poor cannot afford such subsidies face problems of food shortage.
Economic factor - soaring cost of fertilizers and transport
·
As
fuel costs increase, transport of farm produce and cost of fuel for farm
machinery increase as well.
·
e.g. Kazakhstan had
to increase the price of wheat export due to fuel increase in 2011.
·
The
rise and fall in world food prices follows that of oil prices.
·
The
wealthy are more able to absorb the increase in food price as a lower
proportion of their income is spent on food.
·
The poor are unable
to afford enough food when food prices increase.
Economic factor - conversion of farmland
to industrial crop production e.g. biofuel crops
·
Biofuels
are fuels that derive energy from biological carbons instead of fossil fuels
such as coal.
·
Examples
of biofuels are those derived from maize, sugar cane and oil palm
·
25% of all food crops
grown in the USA became fuel for vehicles instead of food for people.
·
Farmland
that could have been used to grow crops for human consumption used to grow
biofuels instead.
·
From
2006 to 2007, 30% increase in food prices related to production of biofuels.
·
The amount of crops
used as biofuel would have been enough to feed 330 million people for one year.
Social factor – Food accessibility
·
Accessibility to food
refers to how easily residents can reach the food that is available.
·
Even
when food is available within a country, how accessible it is depends on the number and location of food outlets.
·
In
LDCs, people may be unable to obtain fresh produce and thus have a smaller food
intake as the food outlets are fewer and farther apart from one another.
Social factor – inadequate logistics of
food distribution and storage
·
Food distribution is
the movement of food from farms to retail outlets.
·
Accessibility may be affected due
to physical factors such as mountains and the occurrences of landslides.
·
When
local production cannot meet local demand, imports are necessary,
·
One-third
of the population of Timor- Leste experiences food shortages between harvests.
This is worsened by a lack of storage facilities and difficulty of accessing
numerous remote communities.
Social - rapid population growth
·
World’s
population will reach 10 billion by 2050.
·
Food
production has to increase to meet the projected population. In Sub-Saharan
Africa, the high population growth has put pressure on limited farmland available.
·
Due
to rising temperatures, existing small amount of land suitable for agriculture
has declined.
·
All
these factors increased the risk of food shortage.
13. Is technology in food production an effective solution to food
shortage?
·
Advances
in technology have increased food production.
·
However,
dealing with food shortage involves management through various perspectives,
including socio-politics and economics.
·
The
use of technology to increase food production may be successful to a certain
extent. However, the strategies may not
be fully effective in solving the problem of food shortage.
