KQ1: How and why has food consumption patterns changed since 1960s?
How do food consumption patterns vary between DCs and LDCs over time?
Variation in global food consumption patterns:
Indicators of food consumption
consumption/kg/yr.
starchy staples as % of all calories;
total calorie intake
Changing food preferences (e.g. rice, meat and fruits)
Why do food consumption patterns vary between DCs and LDCs?
Reasons for the growth and variations in food consumption:
Economic
disposable income,
pricing
Socio-cultural
food preference e.g. organic food and fast food, mitigation
population growth
Political
stability of food supply;
food safety
What are the consequences of variations in food consumption patterns?
Impact of inadequate food consumption on individuals and countries;
Health
malnutrition,
starvation,
Economic
lower productivity,
food aid and economic aid can cause long term debts,
diversion of financial resources to health care
Political
social unrest
Social
scavenging
Impact of excess food consumption on individuals and countries:
Health
obesity and related illness
Economic
lower productivity
diversion of financial resources to health care
Social issues
food wastage
dieting
KQ2: What are the trends and challenges in production of food crops?
How has the production of crops changed since 1960s?
What factors affect the intensity of food production and supply?
Food chain (linkages between consumers, producers and distributors)
Trend in production of food crops (rice and wheat) from 1960s
Increased intensity of production of food crops
Factors affecting the intensity of food production and supply
Physical
relief,
soils & drainage
climate
Economic
purpose of farming; commercial and subsistence;
demand and capital; trade;
Agri-business)
Political
government policy,
ASEAN
Technological advances
Green Revolution through use of high-yielding varieties, irrigation, mechanisation, fertilisers and pesticides
What are the effects of continuing intensification of food production?
Challenges associated with intensification of production of crops from 1960s
Effects of use of irrigation and chemicals on water and soil quality (Salinisation, eutrophication),
Why do food shortages occur?
Physical
extreme weather,
climate change and
pests such as locusts
Political
civil strife,
poor governance
Economic
rising demand for meat and dairy products for meat and dairy products from emerging economies like China and India,
soaring cost of fertilizers and transport,
conversion of farmland to industrial crop production to producebiofuel crops
Social
Lack of accessibility,
inadequate logistics of food distribution and storage,
rapid population growth
KQ3: How can the problem of food shortage be addressed?
What are the strategies to overcome food shortage?
How effective are technological strategies in alleviating the problem of food shortage?
Strategies to overcome food shortage:
Technological
storage (e.g. refrigeration and transport)
Farming technology (e.g. Green Revolution)
Biotechnology: Genetically modified food
characteristics (e.g. high yield and longer shelf life)
positive impacts (e.g. economic and regional development)
Negative impacts (e.g. reduction of biodiversity and habitat loss)
Agricultural
multiple cropping and crop rotation
water and soil conservation
lease of farmland to other countries
Social
support local farmers
population control
Political/economic
food programmes and aid assistance (e.g. UNWFP)
Agricultural policies (e.g. high-tech farming in Singapore
With reference to a case study (e.g. Punjab, India), consider the following guiding questions with regards to its experience of increasing the supply of staple food (e.g. wheat):
1) How has the supply situation of the staple food varied over the last 40 years?
2) How has the area boosted the supply of the staple food?
3) Why is there still a need to boost the supply of the staple food?
4) Has technology helped to make the supply of staple food more sustainable?
