What is Resource Security: Oil, Water & Critical Materials?
Resource security refers to a country's ability to access reliable and affordable supplies of essential resources like oil, water, and critical materials (e.g., lithium for batteries). In an increasingly interconnected and resource-hungry world, competition for these resources is growing, leading to geopolitical tensions. Ensuring resource security is a major challenge that involves managing supply and demand, developing new technologies, and navigating international relations.
Board notes: This is a contemporary global issue that appears in various forms across AQA, Edexcel, and OCR, often within topics on resource management or the changing economic world. The key is to understand the growing global competition for resources and the geopolitical implications.
Step-by-step explanationWorked examples
Worked example
The geopolitical importance of the Strait of Hormuz: This narrow strait between Iran and Oman is a critical chokepoint for global oil supplies, with about 20% of the world's oil passing through it every day. Any disruption to shipping in this strait, for example due to political conflict, could lead to a sharp spike in global oil prices, demonstrating the vulnerability of global energy security to geopolitical events in specific locations.

Common mistakes
- 1Thinking resource security is only a problem for developing countries. Many HICs are highly dependent on imports for their energy and raw materials, making them vulnerable to supply disruptions and price shocks. Japan, for example, imports almost all of its oil.
- 2Focusing only on the quantity of a resource. Resource security is also about the quality and accessibility of the resource. A country might have large water reserves, but if they are polluted or difficult to access, it still faces water insecurity.
- 3Believing that technology will always solve resource shortages. While technology can help (e.g., through desalination or renewable energy), it is not a magic bullet. Reducing consumption and managing resources more efficiently are equally important.

Frequently asked questions
What is water stress?
Water stress occurs when the demand for water exceeds the available amount during a certain period or when poor quality restricts its use. The South East of England is considered a water-stressed region due to its high population density and relatively low rainfall.
Why is lithium a critical material?
Lithium is a vital component in rechargeable batteries used in smartphones, laptops, and, most importantly, electric vehicles. As the world transitions away from fossil fuels, demand for lithium is soaring, leading to a global scramble to secure supplies from countries like Chile, Australia, and China.
