Resource Security, Energy and Food
Resource Security, Energy and Food
This domain examines resource availability, energy mixes, food systems and the water-energy-food nexus. Questions require evaluation of security for different places and of sustainability.
Core rules
- A resource is a naturally occurring substance or feature that is valued; a reserve is the part that is known, economically recoverable and legally accessible.
- Energy security is reliable, affordable access to energy. It depends on domestic supply, imports, infrastructure, price and geopolitics. Energy mix is the share of different sources.
- Food security has four dimensions: availability, access, utilisation and stability. Food security is not the same as food production.
- The water-energy-food nexus recognises trade-offs: biofuel crops use water and land; desalination uses energy; irrigation affects water.
- Sustainable management includes efficiency, diversification, recycling and agroecology.
Worked example
A country with large oil reserves may still have low energy security. Reasoning: reserves do not equal production or refining capacity; conflict or sanctions can disrupt supply; reliance on export revenue exposes the economy to price shocks; lack of grids or storage limits access. Security is about reliable access, not just resource quantity.
Traps
Do not confuse resource and reserve. Do not equate food security with food output. Do not assume renewable energy is always environmentally benign. Do not ignore the nexus.
