Resource management (Edexcel GCSE Geography A): Revision Notes

Global usage and consumption

Introduction to resource consumption patterns

Food, energy and water are essential resources for human survival, but these vital resources are not distributed or consumed equally across the world. Understanding these patterns helps us recognise the significant inequalities that exist between different countries and regions.

The way people consume resources varies dramatically depending on their country's level of development, economic situation, and geographical location. This creates a complex global picture where some nations use far more resources per person than others.

Understanding global resource consumption differences

Energy usage patterns

Energy consumption shows some of the clearest patterns of global inequality. Technically advanced countries like the United States consume enormous amounts of energy to power their industries, transport systems, and modern lifestyles. These wealthy nations have built their economies around high energy use, from air conditioning and heating systems to manufacturing processes and transportation networks.

In contrast, less developed countries such as Sudan have much lower energy consumption levels. This reflects limited industrial development, fewer vehicles, less electricity infrastructure, and generally lower living standards. However, the global picture is changing rapidly as emerging economies grow.

Countries like China represent a third category - nations experiencing rapid industrial development. As China has modernised its economy and improved living standards for its population, energy usage has risen dramatically. This pattern is being repeated across many developing nations as they industrialise.

Food consumption variations

Food consumption patterns also reveal stark global inequalities. Wealthy countries like the USA have high levels of food consumption, with citizens having access to diverse, abundant food supplies. People in these nations typically consume far more calories than needed and have access to processed foods, meat, and imported products year-round.

However, in many parts of Africa and other developing regions, food consumption is much more limited. For example, people in Ghana often survive on fewer than 2000 calories per day, which is below recommended daily requirements. This reflects issues with food security, poverty, agricultural productivity, and distribution systems.

Water usage and availability

Water consumption and availability create another layer of global inequality. The distribution of water resources depends heavily on climate patterns and geographical factors, but consumption also varies based on development levels and lifestyle.

North Africa experiences water deficiency because precipitation levels are much lower than evaporation rates in these arid regions. This creates chronic water shortages that affect agriculture, industry, and daily life for millions of people.

In contrast, tropical rainforest regions often have water surplus, where precipitation exceeds evaporation. Countries in these areas may have abundant freshwater resources, though they may still face challenges in accessing and distributing clean water to their populations.

Measuring and mapping resource consumption

Understanding choropleth maps

Geographers use choropleth maps to display resource consumption data clearly and effectively. These maps use different colours or shading patterns to represent statistical information across different countries or regions. Each colour represents a specific range of values, making it easy to identify patterns and compare different areas.

When interpreting these maps, you need to carefully examine the key or legend to understand what each colour represents. The data ranges help you categorise countries into different consumption levels and identify which regions have the highest and lowest resource usage.

Key consumption statistics

The global inequality in resource consumption is highlighted by some striking statistics. The average daily consumption of resources reaches 90 kilogrammes per person in North America, demonstrating the resource-intensive lifestyles of wealthy nations. This includes everything from food and water to the materials needed for housing, transport, and consumer goods.

In stark contrast, people in Africa consume an average of only 10 kilogrammes of resources per day. This nine-fold difference illustrates the enormous gap between developed and developing nations in terms of resource access and consumption patterns.

Regional examples and case studies

Different regions demonstrate various patterns of resource consumption that reflect their development status, geography, and economic conditions.

Global implications and patterns

These consumption patterns create significant global challenges. Developed nations consume a disproportionate share of the world's resources despite having smaller populations, whilst developing nations often struggle to meet basic needs. As more countries develop economically, global resource consumption continues to rise, creating sustainability challenges.

The uneven distribution also affects international relations, trade patterns, and environmental impacts. Countries with high consumption levels often import resources from developing nations, creating complex global supply chains and dependencies.
