Food resources: demand and supply
Lesson details
Learning outcome
I can explain the reasons for increasing demand for food and factors that affect food supply.
Key learning points
- The global demand for food is rising.
- Food consumption is increasng due to economic development.
- Food consumption is increasing due to population increase.
- Factors affecting food supply include climate, technology, pests and disease, water stress, conflict and poverty.
Keywords
Drought - a long period of time with little or no rainfall, leading to a shortage of water
Irrigation - applying water to land in order to supply crops and other plants
Water stress - occurs when the demand for water exceeds the available amount during a certain period or when poor quality restricts its use
Poverty - more than lack of income, it includes hunger and malnutrition, limited access to education and other basic services
Common misconception
Rising demand for food is simply down to the world's growing population.
This is one reason for growing demand for food but economic development is another factor that affects demand as people become richer they eat more meat and so more grain or land to graze is needed to feed those animals.
Teacher tip
If you have studied the (optional) hot deserts topic you might remind students about the way drought and poverty lead to soil erosion and desertification, affecting food supplies.
