Resource Management in the Human Environment

1. Introduction

Resource management is a core theme in the AQA GCSE Geography unit *Challenges in the human environment*. The exam board recognises that food, water and energy are the three pillars that underpin economic growth, social stability and environmental sustainability. This guide follows the curriculum’s learning objectives and provides a concise, evidence‑based overview of each resource, UK‑specific challenges, and sustainable solutions.

> Key learning objectives > > * Explain the significance of food, water and energy to economic and social well‑being. > * Describe global inequalities in the supply and consumption of resources. > * Describe UK food, water and energy resource issues and propose sustainable strategies.

The guide is structured into three main sections – Food, Water and Energy – each covering global patterns, UK issues and sustainable responses. The content is written in plain language suitable for GCSE revision and includes practical examples, key terms and cross‑cutting themes such as inequality and sustainability.

2. Food

2.1 Global patterns of calorie intake and supply

• Calorie intake varies widely: high‑income countries average ~3,000 kcal day⁻¹, while many low‑income countries average <2,000 kcal day⁻¹.
• Food supply is uneven; 70 % of the world’s food is produced in just 20 % of the land area, largely in temperate zones.

2.2 Drivers of increasing food consumption

• Economic development raises purchasing power, leading to higher meat and processed‑food consumption.
• Population growth (≈1.1 % p.a.) increases total demand.
• Urbanisation shifts diets toward convenience foods and larger portion sizes.

2.3 Factors affecting food supply

| Factor | Impact | Example | |--------|--------|---------| | Climate change | Alters growing seasons, increases extreme weather | Drought in Sub‑Saharan Africa reduces maize output | | Technology | Irrigation, GM crops increase yield | High‑yield rice varieties in Asia | | Pests & disease | Crop losses, price spikes | Locust swarms in East Africa | | Water stress | Limits irrigation | Over‑extraction in the Nile Basin | | Conflict & poverty | Disrupts markets, limits access | Syrian civil war causing food shortages |

2.4 Impacts of food insecurity

• Famine and undernutrition lead to high child mortality.
• Soil erosion from over‑cultivation reduces future productivity.
• Rising prices can trigger social unrest (e.g., 2008 food riots in West Africa).

2.5 Strategies to increase food supply

• Irrigation, aeroponics, hydroponics: grow crops with less water and land.
• New Green Revolution: GM crops resistant to pests and drought.
• Biotechnology: precision breeding for higher yields.
• Appropriate technology: low‑cost, locally adapted farming tools.

2.6 Sustainable food supply strategies

| Strategy | Description | UK Context | |----------|-------------|------------| | Organic farming | Reduces synthetic inputs, improves soil health | 1.5 % of UK farmland is certified organic | | Permaculture | Design food systems that mimic natural ecosystems | Community gardens in London | | Urban farming | Uses rooftops, balconies, vertical farms | 3 % of UK food produced in cities | | Sustainable fish & meat | Rotational grazing, aquaculture with closed‑loop systems | UK’s move to plant‑based diets | | Seasonal consumption | Reduces transport and storage needs | “Seasonal menus” in supermarkets | | Waste reduction | Composting, food‑sharing apps | Food‑Waste Reduction Initiative |

2.7 Local example – Community Supported Agriculture (CSA)

• Advantages: Fresh produce, local employment, reduced transport emissions.
• Disadvantages: Limited scale, higher cost to consumers, seasonal variability.

3. Water

3.1 Global patterns of surplus and deficit

• Water surplus: Amazon basin, Congo basin – abundant rainfall and low demand.
• Water deficit: Middle East, parts of Australia – high temperatures, low rainfall.
• Transboundary rivers (e.g., Nile, Mekong) create geopolitical tensions.

3.2 Drivers of increasing water consumption

• Economic development: industrial processes, domestic appliances.
• Population growth: more households, more irrigation.
• Urbanisation: increased demand for potable water and sanitation.

3.3 Factors affecting water availability

| Factor | Impact | Example | |--------|--------|---------| | Climate change | Alters precipitation patterns, increases evaporation | Drought in California | | Geology | Determines aquifer recharge rates | Karst aquifers in the UK are vulnerable | | Pollution | Reduces usable water quality | Sewage discharge into the Thames | | Over‑abstraction | Lowers groundwater levels | Over‑extraction in the North Sea basin | | Limited infrastructure | Inadequate storage, distribution | Rural water shortages in India | | Poverty | Limits access to clean water | Lack of piped water in sub‑Saharan villages |

3.4 Impacts of water insecurity

• Waterborne disease: cholera, dysentery.
• Food production impacts: reduced crop yields, livestock stress.
• Industrial output impacts: factory shutdowns due to water shortages.
• Conflict potential: competition over scarce water resources.

3.5 Strategies to increase water supply

• Diversion schemes: canals, pipelines to move water from surplus to deficit areas.
• Storage: dams, reservoirs, underground cisterns.
• Desalination: converting seawater to potable water.
• Water‑saving technologies: low‑flow taps, grey‑water recycling.

3.6 Sustainable water strategies

| Strategy | Description | UK Context | |----------|-------------|------------| | Water conservation | Behavioural changes, efficient appliances | “Water‑wise” campaigns | | Groundwater management | Recharge wells, controlled abstraction | UK’s Groundwater Management Plan | | Recycling & grey‑water | Treating wastewater for irrigation or flushing | 10 % of UK households use grey‑water | | Rainwater harvesting | Collecting roof runoff for non‑potable use | 5 % of UK homes have rain barrels |

3.7 Local example – River Thames Water Transfer

• Advantages: Provides water to London during dry periods, supports industry.
• Disadvantages: High construction cost, ecological disruption, public opposition.

• Environmental costs: pollution, habitat loss from extraction.
• Food production impacts: energy‑intensive agriculture.
• Industrial output impacts: production halts, supply chain disruptions.
• Conflict potential: competition over oil‑rich regions.

4.5 Strategies to increase energy supply

• Renewable expansion: wind, solar, hydro, bioenergy.
• Non‑renewable extraction: oil, gas, coal (with carbon capture).
• Energy efficiency: building insulation, smart grids.
• Demand reduction: behavioural change, low‑energy appliances.

4.6 Sustainable energy strategies

| Strategy | Description | UK Context | |----------|-------------|------------| | Renewable energy | Wind farms, solar arrays, tidal power | 45 % of UK electricity from renewables | | Energy efficiency | Retrofit housing, smart meters | UK’s Energy Efficiency Obligation | | Carbon footprint reduction | Individual lifestyle changes, public transport | “Low‑carbon lifestyle” campaigns | | Sustainable design | Passive houses, green roofs | UK’s Green Building Council standards |

5. Cross‑cutting Themes

1. Inequality – The curriculum emphasises that resource distribution is uneven. Low‑income countries often have high consumption of water and energy per capita but limited access to clean food.
2. Sustainability – All three resources require balancing present needs with future availability. Sustainable strategies often involve technology, policy and behavioural change.
3. Governance – Effective water transfer schemes, food subsidies and energy subsidies illustrate the role of government in managing resources.

6. Revision Tips

• Remember the three pillars: food, water, energy – each with global patterns, UK issues and sustainable solutions.
• Use tables to compare drivers, impacts and strategies – they are exam‑friendly.
• Link to real‑world examples (e.g., UK food miles, Thames water transfer, Hornsea wind farm) to demonstrate application of concepts.
• Practice mapping: draw a simple diagram showing how a change in one resource (e.g., water scarcity) cascades to food and energy.
