Food Security: Definition & Dimensions
Introduce the concept of food security, examining its four dimensions: availability, access, utilisation, and stability.
Key Questions
- Explain the four dimensions of food security and their interrelationships.
- Analyze how different factors can impact food availability and access in a community.
- Differentiate between chronic and acute food insecurity.

About This Topic
Food Waste and Consumption examines the environmental and social impact of our dietary choices and the inefficiencies of global supply chains. This topic (AC9G9K02) investigates why one-third of all food produced globally is wasted and the massive resource cost (water, land, energy) that this waste represents. Students look at the difference between 'food loss' in developing nations and 'food waste' in developed countries like Australia.
Students will also explore how consumer demand for 'perfect' produce and year-round availability drives waste and environmental degradation. This unit encourages students to take responsibility for their own consumption patterns. Students grasp this concept faster through conducting their own 'waste audits' and designing local solutions to reduce food waste.
Active Learning Ideas
Simulation Game: The Waste Audit
Students track the food waste in their own lunch or at home for a day. They categorise the waste and calculate the 'hidden' water and energy used to produce the food they threw away.
Inquiry Circle: The 'Ugly' Food Campaign
Groups design a marketing campaign to encourage people to buy 'imperfect' fruit and vegetables. They present their posters and slogans to the class.
Think-Pair-Share: Why do we waste?
Students discuss in pairs the top three reasons they think food is wasted in their homes. They then brainstorm one practical change they could make to reduce it.
Watch Out for These Misconceptions
Common MisconceptionFood waste is only a problem because people are hungry.
What to Teach Instead
It's also a massive environmental problem, as rotting food in landfills produces methane, a powerful greenhouse gas. Using a 'consequence web' helps students see these environmental links.
Common MisconceptionMost food waste happens in supermarkets.
What to Teach Instead
In Australia, the majority of food waste actually happens in our own homes. A 'waste breakdown' chart helps students see where the real problem lies.
