Resource management — AQA GCSE Geography

Food, water, and energy are the three essential resources required for human survival and advancement. Human development relies on a secure supply of these resources to improve quality of life and standard of living. Food provides the necessary calories and nutrients for physical health, enabling people to work and attend school. Water is vital for drinking, sanitation, and agriculture; without clean water, waterborne diseases spread, reducing life expectancy. Energy is required for heating, transport, and powering industries, which drives economic growth. When a country has abundant access to these resources, its population can focus on education and economic activities rather than subsistence, leading to higher levels of human development.

Food, water, and energy are critical for economic and social well-being. Social well-being encompasses the health, happiness, and education of a population. Access to nutritious food and clean water prevents malnutrition and diseases, allowing children to attend school and adults to lead healthy lives. Economic well-being relates to wealth and employment. Energy is essential for powering factories, running transport, and supporting agriculture, which create jobs and generate income. For example, reliable electricity allows businesses to operate efficiently, boosting the economy. Conversely, a lack of these resources traps populations in poverty, as time is spent securing basic needs rather than engaging in productive economic activities.

Global inequalities in the supply and consumption of resources are driven by variations in climate, geology, and economic development. High-income countries (HICs) like the USA consume a disproportionately large share of global food, water, and energy resources due to high living standards and industrial demand. Conversely, many low-income countries (LICs) face resource deficits, struggling with inadequate supply despite sometimes possessing abundant natural reserves, often due to a lack of infrastructure or capital to exploit them. Newly emerging economies (NEEs) such as China are experiencing rapid increases in consumption as their populations grow wealthier and industrialise. This imbalance creates a global divide where resource security is concentrated in wealthier nations, leaving poorer regions vulnerable to shortages.

The UK faces significant shifts in the demand and provision of food, water, and energy, creating both opportunities and challenges. Food demand is changing towards seasonal produce year-round, increasing reliance on imports and raising food miles, which challenges efforts to reduce carbon footprints. However, this creates opportunities for agribusinesses and local farm shops promoting organic produce. Water provision is challenged by a spatial imbalance: high demand in the drier South East and high supply in the wetter North and West, necessitating costly water transfer schemes. Energy provision is transitioning from fossil fuels to renewable sources like wind and solar. While this shift requires massive infrastructure investment, it provides opportunities for green jobs and improved sustainability.

This section provides a broad overview of how essential resources—specifically food, water, and energy—are managed within the United Kingdom. Students must understand the changing demand and provision of these resources across the UK. For example, population growth and changing lifestyles increase demand, while domestic supply often struggles to keep pace, leading to a reliance on imports. You should explore spatial inequalities in resource distribution, such as water surplus in the north and west contrasting with water deficit in the south and east. The overview requires an understanding of the economic and environmental issues associated with resource exploitation, consumption, and the transition towards sustainable management in the UK.

This topic focuses specifically on the provision and demand for food within the UK. Students must explore the growing demand for high-value food exports from lower-income countries and all-year-round seasonal produce, which has significantly increased the UK's reliance on global food supply chains. You need to understand the concept of 'food miles' and the associated carbon footprint generated by transporting food. The section also covers the trend towards agribusiness and large-scale industrial farming in the UK, aimed at maximising production and efficiency. Furthermore, you should examine the environmental and economic impacts of these agricultural changes, alongside the growing movement towards local sourcing and organic farming.

The UK's food consumption patterns have changed significantly, leading to increased imports. There is a growing demand for high-value food exports, such as exotic fruits, coffee, and spices, from low-income countries (LICs). This provides income for LICs but can reduce land available for local food production. Additionally, UK consumers now expect all-year demand for seasonal food, meaning crops like strawberries or green beans are imported from countries like Kenya or Spain when out of season in the UK. Furthermore, there is a rising demand for organic produce, grown without artificial chemicals, which is often imported if UK supply cannot meet the demand. These trends reflect changing diets and higher disposable incomes.

Importing food globally increases the number of 'food miles' travelled, which is the distance food is transported from producer to consumer. This transportation, often by air freight or refrigerated ships, burns fossil fuels and releases greenhouse gases, resulting in larger carbon footprints for the food consumed. To combat this environmental impact, there are growing moves towards local sourcing of food. Consumers and supermarkets are increasingly buying food produced within the UK, such as from farm shops or farmers' markets. This reduces food miles and carbon emissions, supports local farmers, and ensures seasonal eating, though it may limit the variety of foods available year-round.

Agribusiness applies corporate business skills to agriculture, treating farming as a large-scale commercial enterprise. In the UK, the trend towards agribusiness aims to maximise food production and profitability. Smaller farms merge to create larger units, achieving economies of scale. These farms are highly capital-intensive, relying on advanced mechanisation like GPS-guided tractors rather than human labour. They utilise intensive methods, including high inputs of artificial fertilisers and pesticides to boost yields. For example, in East Anglia, large arable agribusinesses produce wheat efficiently but often cause hedgerow removal and reduced biodiversity. This trend increases domestic food security but raises environmental concerns.

This statement introduces the 'Water' subsection within Resource Management. Students must understand water as a critical resource, exploring its provision in the UK and globally. The guided reading should focus on the spatial imbalance between water supply and demand. In the UK, this involves contrasting the water surplus in the north and west with the water deficit in the south and east. Learners should explore how population growth and changing habits increase demand, while pollution threatens water quality. The topic also covers management strategies, such as water transfer schemes and conservation methods, to ensure future water security. Students should use maps and data to analyse these patterns and evaluate sustainability.

In the UK, the demand for water has been steadily increasing due to several factors. A growing population means more individuals require water for domestic use. Furthermore, modern lifestyles involve a higher use of water-intensive appliances such as washing machines, dishwashers, and power showers. Industrial and agricultural demands also contribute to this change, with increased manufacturing and irrigation needs. The spatial distribution of this demand is uneven; the South East of England experiences the highest demand due to its dense population, yet it receives the lowest annual rainfall, leading to water stress. Understanding these changing patterns is crucial for effective resource management and planning future water infrastructure.

Maintaining water quality in the UK is challenging due to various pollution sources. Agricultural runoff introduces fertilisers into watercourses, leading to eutrophication which depletes oxygen and harms aquatic life. Industrial discharges release toxic chemicals, while domestic sources contribute sewage and microplastics. Managing this pollution involves strict legislation and monitoring by the Environment Agency. Water treatment plants use filtration and chemical purification to ensure water is safe for consumption. Additionally, educational campaigns and improved agricultural practices, such as buffer strips, help manage and reduce pollution at its source, protecting both human health and vital aquatic ecosystems across the country.

Balancing the availability of resources (supply) with the requirement for them (demand) is crucial. When supply exceeds demand, an area experiences a resource surplus, having more than enough to meet its needs. Conversely, when demand outstrips supply, an area faces a resource deficit, leading to shortages. For example, in the UK, the north and west often have a water surplus due to high rainfall and lower population density. Meanwhile, the south and east experience a water deficit because of lower rainfall and a high population. Matching supply and demand involves identifying these spatial imbalances and planning strategies to ensure that areas of deficit can secure adequate resources, often by redistributing them from areas of surplus.

To address spatial imbalances where resource demand exceeds local supply, transfer schemes are necessary to maintain adequate supplies. These schemes involve moving resources, such as water, from areas of surplus to areas of deficit via infrastructure like pipelines or aqueducts. For instance, water transfer in the UK might involve moving water from reservoirs in the high-rainfall regions of Wales to the densely populated, drier areas of the West Midlands or London. While these transfers are essential to prevent shortages, support economic growth, and maintain living standards in deficit areas, they can be controversial due to high economic costs, environmental impacts on the source area, and greenhouse gas emissions from pumping stations.

This section introduces energy as a fundamental resource driving the UK's economic and social development. Students must understand the broad context of national energy provision, including how fluctuating demand is met and the diverse sources utilised. The study of energy encompasses the spatial distribution of resources across the UK, from North Sea oil and gas to coastal wind farms. It establishes the foundation for exploring energy security, the transition from traditional to modern generation methods, and the complex economic and environmental issues associated with energy exploitation. You will need to evaluate the strategies required to ensure a sustainable and secure energy future for the UK.

This topic explores the evolution of the UK's energy mix, highlighting the transition from a historical reliance on fossil fuels to the growing significance of renewables. Students must understand that while coal once dominated, its use has drastically declined due to environmental regulations and depleted reserves. Conversely, renewable sources like wind, solar, and biomass have expanded rapidly, driven by government targets to reduce carbon emissions and combat climate change. Despite this green transition, fossil fuels, particularly natural gas, remain crucial for providing a reliable supply when renewable generation fluctuates. You must be able to explain the economic, environmental, and political factors driving these changes.

The UK has experienced a significant reduction in its domestic supplies of coal, gas, and oil. This decline is driven by the physical exhaustion of easily accessible reserves, economic factors, and environmental policies. For example, the UK's deep coal mining industry effectively ended in 2015 with the closure of Kellingley Colliery, as importing coal became cheaper. Similarly, production of oil and gas from the North Sea peaked around 1999 and has steadily declined as the most accessible reserves have been depleted. Consequently, the UK has transitioned from being a net exporter of energy to relying heavily on imported fossil fuels to meet its energy demands, which directly impacts national energy security.

Exploiting energy sources creates distinct economic and environmental issues. Economically, extracting fossil fuels or building renewable infrastructure requires massive capital investment, but it generates employment and boosts local economies. However, reliance on imported fuels exposes countries to volatile global prices. Environmentally, fossil fuel extraction often leads to habitat destruction, groundwater contamination, and significant greenhouse gas emissions. For example, fracking for shale gas can cause minor seismic activity and water pollution. Renewable sources also have environmental costs; large wind farms can cause visual and noise pollution, while hydroelectric dams flood large areas of land, destroying local ecosystems.
