resource management overview

Answer: 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).

Answer: 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.

Answer: 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.

Answer: 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.

Answer: 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.

Answer: 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.
