G38: Resource Management Overview
Understanding the significance of food, water and energy resources, global inequalities in their distribution, and the UK's demand and provision for each.
🌍 Why Resources Matter
Key Concept: Resources are the materials and services that people need to survive and maintain a good quality of life. The three fundamental resources are food, water, and energy. Access to these resources varies enormously across the globe and within countries.
The significance of each resource:
- Food: Essential for survival, health, and development. Inadequate nutrition causes stunted growth, disease, and reduced economic productivity
- Water: Needed for drinking, sanitation, agriculture, and industry. Water scarcity affects over 2 billion people globally
- Energy: Powers industry, transport, heating, and technology. Access to energy is closely linked to economic development and quality of life
The Resource Nexus: Food, water, and energy are interconnected. Producing food requires water and energy. Providing energy often needs water (for cooling power stations). Pumping water requires energy. A shortage in one resource can trigger shortages in the others.
📊 Global Inequalities in Resource Distribution
| Resource | Key Inequality | Scale of the Problem |
|---|---|---|
| Food | Over 800 million people are undernourished while 1.9 billion are overweight or obese | Sub-Saharan Africa has the highest hunger rates; 20% of the population is undernourished |
| Water | 2.2 billion people lack safely managed drinking water; 4.2 billion lack safe sanitation | Water scarcity affects 40% of the global population; by 2025, 1.8 billion may face absolute water scarcity |
| Energy | 770 million people lack access to electricity; 2.6 billion rely on polluting cooking fuels | Sub-Saharan Africa has the lowest energy access; some countries have less than 10% electrification |
Key Point: Resource distribution is uneven due to physical factors (climate, geology, rainfall), economic factors (wealth, technology, infrastructure), and political factors (governance, conflict, trade policies). The relationship between resource availability and development is two-way: poverty limits access to resources, and poor resource access perpetuates poverty.
🇬🇧 UK Food Demand and Provision
The UK Food Supply
- The UK produces approximately 60% of its food by value (75% of indigenous-type foods)
- The remaining 40% is imported from over 160 countries
- Major imports: fruit and vegetables (from Spain, Netherlands), meat (from Ireland, Denmark), cereals (from Canada, USA)
- Major exports: whisky, salmon, cheese, lamb
Food Miles
Definition: Food miles measure the distance food travels from production to consumption. Higher food miles mean greater carbon emissions from transport, contributing to climate change.
Example: Food Miles in the UK
A typical UK supermarket basket of 20 imported items may have travelled over 100,000 miles combined. Green beans flown from Kenya to the UK travel approximately 6,800 miles, producing around 2.6 kg of CO₂ per kg of beans. In contrast, locally produced UK green beans (in season) travel far fewer miles. However, the argument is complex - producing certain foods in heated UK greenhouses can use more energy than growing them naturally abroad and shipping them.
Agribusiness
Definition: Agribusiness is large-scale, commercial farming that uses technology, chemicals, and economies of scale to maximise production and profit. It contrasts with traditional small-scale farming.
| Characteristics of Agribusiness | Impacts |
|---|---|
| Large farm sizes (hundreds to thousands of hectares) | Small farms bought up and consolidated, reducing rural employment |
| Mechanisation (tractors, combine harvesters, drones) | Fewer workers needed; rural depopulation |
| Chemical inputs (fertilisers, pesticides, herbicides) | Water pollution (eutrophication); soil degradation; biodiversity loss |
| Monoculture (growing a single crop over large areas) | Soil nutrient depletion; vulnerability to pests and diseases |
| High yields and efficiency | Cheaper food for consumers; increased UK food security |
Organic and Local Food
Alternatives to agribusiness include organic farming (no artificial chemicals, higher animal welfare standards, lower yields) and local food schemes (farmers' markets, veg boxes, community-supported agriculture). These reduce food miles and support local economies but typically cost more and cannot feed the entire population at current consumption levels.
💧 UK Water Demand and Provision
UK Water Supply
- The UK has relatively high rainfall (1,100mm average) but it is unevenly distributed - the west and north are wet, the east and south are drier
- Water companies supply approximately 15 billion litres per day to households and businesses
- Average UK water consumption is approximately 140 litres per person per day
- Population growth and climate change are increasing pressure on supplies
The Water Supply-Demand Imbalance
Key Problem: The areas of highest water demand (south and east England, where population is concentrated) have the lowest rainfall. The areas of highest rainfall (Wales, northern England, Scotland) have lower demand. This mismatch creates supply problems, especially during droughts.
Water Transfer Schemes
Definition: Water transfer schemes move water from areas of surplus to areas of deficit through pipelines, canals, and rivers.
Example: Kielder Water and Thirlmere Transfer
Kielder Water in Northumberland is the largest artificial lake in northern England (52 billion litres). Built in 1982, it transfers water via tunnels and pipelines to the industrial areas of Tyne and Wear. However, the original demand from heavy industry never fully materialised due to de-industrialisation, so the scheme operates below capacity. The Thirlmere Transfer in the Lake District has supplied water to Manchester since 1894 via a 96-mile aqueduct. Water transfer schemes can cause environmental disruption during construction and may transfer invasive species between river systems.
Managing Water Demand
- Metering (houses with meters use 15-20% less water)
- Leak reduction (water companies lose approximately 3 billion litres per day through leaks)
- Water-efficient appliances (low-flow showers, dual-flush toilets)
- Rainwater harvesting and greywater recycling
- Hosepipe bans during droughts
⚡ UK Energy Demand and Provision
The UK Energy Mix
| Energy Source | % of UK Electricity (2023) | Advantages | Disadvantages |
|---|---|---|---|
| Natural gas | 34% | Flexible; relatively cheap; lower CO₂ than coal | Imported (vulnerable to price changes); finite resource; still produces CO₂ |
| Wind (onshore and offshore) | 28% | Renewable; no CO₂ in operation; UK has excellent wind resources | Intermittent (doesn't blow all the time); visual impact; expensive to build offshore |
| Nuclear | 15% | Low CO₂; reliable baseload; high energy density | Radioactive waste; expensive to build and decommission; safety concerns |
| Solar | 5% | Renewable; falling costs; easy to install | Intermittent; UK has limited sunshine; requires large areas |
| Biomass | 6% | Can use waste; theoretically carbon-neutral | Land use competition with food; transport emissions |
| Coal | 1% | Abundant historically; cheap | Highest CO₂ emissions; air pollution; most UK mines closed |
| Hydro | 2% | Renewable; reliable; long lifespan | Limited UK sites; environmental damage from dams |
| Imports | 9% | Ensures supply during peak demand | Dependence on other countries; vulnerable to price changes |
Key Trend: The UK's energy mix has shifted dramatically. In 1990, coal generated 67% of UK electricity. By 2023, coal contributed just 1%, while renewables (mainly wind) grew from under 2% to over 40%. The UK aims to reach net zero carbon emissions by 2050, requiring further expansion of renewables and new nuclear capacity (Hinkley Point C is under construction, expected to provide 7% of UK electricity).
Economic and Environmental Issues
- Energy security: The UK became a net energy importer in 2004 as North Sea oil and gas declined; reliance on imported gas (from Norway, Qatar, USA) creates price vulnerability (demonstrated by the 2022 energy price crisis after Russia invaded Ukraine)
- Climate change: The UK has legally binding targets to reduce CO₂ emissions; phasing out fossil fuels is essential but requires massive investment in renewables, storage, and grid infrastructure
- Nuclear debate: New nuclear plants are expensive (Hinkley Point C costs have risen to over £32 billion) and produce radioactive waste, but provide reliable low-carbon electricity
- Fracking: Hydraulic fracturing for shale gas was controversially trialled in Lancashire but paused in 2019 due to earthquake concerns; it could increase UK energy security but risks water contamination and greenhouse gas emissions

✅ Answers
- Resource distribution is uneven due to physical factors (climate affects food growing and water availability; geology determines fossil fuel and mineral deposits; rainfall varies enormously between regions), economic factors (wealth determines the ability to extract, process, and distribute resources; technology enables exploitation but is expensive), and political factors (conflict disrupts supply; trade policies restrict access; governance affects how resources are managed and distributed).
- Food miles measure the distance food travels from production to consumption. They are a concern because longer transport distances produce more carbon emissions (e.g. green beans from Kenya to the UK travel 6,800 miles, producing 2.6 kg CO₂ per kg). Reducing food miles can lower the carbon footprint of food. However, the issue is complex - some foods grown abroad naturally may have a lower overall footprint than those grown in heated UK greenhouses.
- Advantages: agribusiness produces high yields efficiently through mechanisation and economies of scale; it provides cheaper food for consumers; it increases UK food security by producing 60% of food needs. Disadvantages: it causes environmental damage (chemical runoff causing eutrophication, soil degradation, biodiversity loss from monoculture); it reduces rural employment through mechanisation; it consolidates small farms into large operations, changing rural communities.
- The UK's water supply-demand imbalance exists because areas of highest demand (south and east England, densely populated) have the lowest rainfall, while areas of highest rainfall (Wales, north, Scotland) have lower demand. Water transfer schemes address this by moving water from surplus to deficit areas. For example, Kielder Water in Northumberland stores water and transfers it to Tyne and Wear via pipelines. However, transfers are expensive to build, can cause environmental disruption, and may transfer invasive species.
- Since 1990, the UK's energy mix has shifted dramatically from fossil fuels to renewables. Coal fell from 67% to 1% due to climate change targets and the carbon tax; renewables (especially wind) grew from under 2% to over 40%, supported by government subsidies and falling technology costs; gas remained important at around 34%, replacing coal as the dominant fossil fuel; nuclear declined slightly as old plants closed. These changes were driven by climate change legislation (Climate Change Act 2008, net zero by 2050), EU renewable energy targets, and the declining competitiveness of coal.
- A balanced view recognises both the benefits and challenges of energy self-sufficiency. Self-sufficiency would increase energy security (reducing vulnerability to imported gas price shocks, as seen in 2022), reduce dependence on potentially unreliable suppliers, and create domestic jobs in renewables and nuclear. However, complete self-sufficiency is unrealistic and potentially undesirable: the UK still needs some gas during the transition; international trade in energy provides flexibility; some energy imports (e.g. from Norway's hydropower) are low-carbon; and the cost of total self-sufficiency would be enormous. A more realistic goal is diversifying supply sources and maximising domestic renewable generation.
🎯 Exam Tips
- Know the UK's approximate food self-sufficiency (60%), water consumption (140 litres/day), and energy mix percentages
- Use specific examples: Kielder Water for water transfer, Hinkley Point C for nuclear, food miles from Kenya
- For resource questions, always link the three resources (food-water-energy nexus)
- Evaluate agribusiness using both environmental and economic arguments
- Remember the spatial mismatch in UK water: high demand in the dry south-east, high supply in the wet north-west
- Higher mark questions: consider trade-offs between different strategies (e.g. cheap food vs environmental damage)
