What this dot point is asking

OCR wants you to explain sustainability of food and food security, the factors that threaten the food supply, and how reducing and recycling waste helps. These are the bigger-picture, global topics in Section B.

Sustainable food production

Ways to produce food more sustainably include sustainable fishing (quotas, larger net holes, avoiding overfishing), farming that protects soil and biodiversity (crop rotation, less chemical use), cutting food miles by buying local and seasonal, using water and energy efficiently, and reducing food waste.

Food security

Factors that threaten food security:

  • A rising world population needing more food from the same or less land.
  • Climate change and extreme weather (droughts, floods) damaging harvests.
  • Rising food and fuel prices, making food less affordable (food poverty).
  • Loss of farmland to building, or soil degradation and erosion.
  • Pests, crop disease and the loss of crop variety (relying on few crops is risky).
  • War and conflict, and over-reliance on imports that can be cut off.

A 6-mark free-response question.

Food security means that all people, at all times, have reliable access to enough safe, nutritious and affordable food to lead a healthy life. A country or household with food security can be confident of its food supply.

Factors that threaten food security: a rising world population needing more food; climate change and extreme weather (droughts, floods) damaging harvests; rising food and fuel prices making food less affordable (food poverty); loss of farmland to building or soil degradation; pests, crop disease and the loss of crop variety; war and conflict disrupting supply; and reliance on imports that can be cut off.

Top-band answers (5 to 6 marks) define food security and explain several distinct threats clearly.

A 4-mark structured question.

Sustainable food production means producing food in a way that meets today's needs without damaging the environment or using up resources so that future generations can still produce food.

Two ways (any two): use sustainable fishing (quotas, avoiding overfishing) to protect fish stocks; farm in ways that protect soil and biodiversity (crop rotation, less chemical use); cut food miles by producing and buying locally and seasonally; reduce food waste; and use water and energy efficiently.

Markers reward defining sustainability (meeting needs now without harming the future) and two valid methods.
