Topic Synopsis
This topic explores the variations in water consumption patterns between developed and developing/emerging countries, specifically examining the proportions used by agriculture, industry, and domestic sectors, and the reasons behind these differences.
Key Concepts & Core Principles
- Water consumption patterns: the amount of water used per person per day, varying greatly between developed (300-500 litres) and developing countries (20-50 litres).
- Virtual water: the hidden water used to produce goods and services, especially food and clothing, which is often imported by developed countries.
- Sectoral differences: in developed countries, industry and agriculture dominate water use (e.g., 70% for agriculture globally, but higher in developing countries), while domestic use is a smaller share.
- Water scarcity: physical scarcity (lack of water) vs. economic scarcity (lack of infrastructure to access water), with developing countries often facing the latter.
- Factors affecting consumption: climate, wealth, technology, government policy, and cultural habits all influence how much water is used.
Exam Tips & Revision Strategies
- Ensure you can distinguish between the water usage sectors (agriculture, industry, domestic) for different levels of development.
- Be prepared to explain the 'why' behind the differences, such as economic structure, technology, and population needs.
Examiner Marking Points
- Proportion of water used by agriculture, industry, and domestic sectors in developed countries
- Proportion of water used by agriculture, industry, and domestic sectors in emerging or developing countries
- Reasons for differences in water usage between developed and emerging/developing countries
