Reasons for Changing Global Supply
Geography: Cambridge International GCSE (2027 Exams), topic 10.2.2
Global Changes in Food Production and Consumption
Global shifts in food supply and demand result from population growth, income changes, technology, and climate effects on production and consumption patterns.
Population growth and food demand
- The global population rise increases food demand worldwide.
- Youthful populations in developing countries boost consumption growth.
- Urbanisation alters diets, increasing demand for processed and diverse foods.
- Trends drive changes in global food production to meet demand.
Income change and consumption
- Rising incomes enable people to buy more and varied foods.
- More meat, dairy, and processed foods are consumed with higher living standards.
- In lower-income countries, diets shift from staples to protein-rich foods.
- In richer countries, food consumption patterns may stabilise or move towards health-conscious choices.
Technological advances
- Technological improvements increase agricultural yields globally.
- Mechanisation, irrigation, and improved crop varieties boost food supply.
- Agriculture uses biotechnology for pest resistance and higher nutrition.
- Technologies enable global food trade, linking producers and consumers worldwide.
Climate change effects
- Climate change causes droughts, floods, and temperature shifts, impacting crop yields.
- Some regions face reduced productivity, risking food shortages.
- Other areas may see new opportunities for farming due to changing climates.
- Adapting agriculture to climate change is vital to maintain the global food supply.
Changing consumption patterns
- Global demand for diverse, convenient, and processed foods rises.
- Increased food waste and resource use affect the sustainability of supply.
- Global trade spreads food seasonality and variety.
- These consumption trends require adapting food production and distribution systems.
