The UK's Resource Situation

🇬🇧 The UK's Resource Situation

The United Kingdom is a wealthy country with well-developed infrastructure — but it faces real resource challenges that illustrate how resource insecurity is not limited to low-income countries. Understanding the UK's specific situation is important for exam questions that require domestic examples alongside global ones.

UK Food: High Imports, Growing Vulnerabilities

The UK imports approximately 46% of its food, worth over £50 billion per year. The UK is broadly self-sufficient in cereals (wheat, barley), dairy, and some meats — but heavily dependent on imports for fruit and vegetables. Around 97% of the tomatoes consumed in the UK are imported, mostly from Spain and the Netherlands. Nearly all citrus fruit, bananas, and coffee come from overseas.

This import dependence creates vulnerabilities:

• Brexit supply chain disruption — changes to customs and border arrangements after 2020 increased delays and costs for food imports from the EU, contributing to supermarket shortages in early 2021.
• Global price volatility — Russia's invasion of Ukraine in 2022 blocked exports of Ukrainian wheat and sunflower oil (Ukraine provides roughly 50% of global sunflower oil), causing price spikes in UK supermarkets within months.
• Climate impacts on British farming — the UK's changing climate (wetter winters, drier summers) is expected to reduce yields of some crops and make growing conditions less predictable. The 2022 summer drought in the UK was the driest since 1976.
• Environmental footprint — the UK food system accounts for approximately 30% of all UK greenhouse gas emissions when land use change overseas is included. This creates pressure to reform food production and reduce meat consumption.

UK Water: Wet Country, Stressed Region

The UK has a reputation as a rainy country — and nationally, it does receive reasonable rainfall (around 1,100mm per year on average). But this masks an extreme regional imbalance:

• North and West — the Scottish Highlands, Lake District, and Wales receive well over 2,000mm per year — some upland areas receive over 4,000mm. Population density is relatively low.
• South and East — receives under 600mm per year in many areas; this is similar to semi-arid regions. Yet this is where most of England's population is concentrated — Greater London (9 million people), the South East, and East Anglia.

South-East England is classified as "seriously water-stressed" by the Environment Agency — meaning demand exceeds 40% of available supply. Thames Water, which supplies London and the Thames Valley, loses approximately 24% of its supply through leakage in its aging pipe network. By the 2050s, climate projections suggest South-East England will experience 15–25% drier summers, while the population continues to grow. New reservoirs, water transfer schemes, and widespread household metering are all under consideration.

UK Energy: Transition in Progress

The UK's energy mix has changed dramatically in the past 15 years. Coal, which supplied over 40% of UK electricity in 2010, has been almost completely phased out — the last coal-fired power station closed in 2024. Wind and other renewables now provide over 32% of electricity, and the government has set a target of clean power by 2030.

But the UK faces significant energy challenges:

• North Sea decline — UK oil and gas production in the North Sea has been falling for decades as reserves deplete; the UK is increasingly a net importer of fossil fuels.
• Heating dependency — approximately 80% of UK homes use gas boilers for heating and hot water. Replacing these with heat pumps or hydrogen as part of the transition to net zero will cost tens of billions of pounds.
• Intermittency — wind and solar are intermittent: they generate electricity only when the wind blows and the sun shines. Storing excess electricity for calm or cloudy periods is a major engineering and cost challenge.
• Opportunity: offshore wind — the UK has some of the best offshore wind resources in the world. Hornsea One, opened in 2019 off the Yorkshire coast, was the world's largest offshore wind farm at 1.2 GW capacity, powering over 1 million homes.
