Globalisation of Food Supplies: Reasons and Impacts
Globalisation of Food Supplies: Reasons and Impacts
Globalised food supply is caused by economic, social, and environmental changes, with many impacts.
Economic causes
Economic causes
- Economic development increases demand for a wide variety of foods.
- Exports and imports allow countries to sell and buy food across borders.
- Better transport and freezing technologies make long-distance food trade possible.
- Urbanisation reduces farmland but increases demand in cities.
- Foreign investment helps food companies grow and trade globally.
Social causes
Social causes
- A larger workforce and rural-to-urban migration support food production in cities.
- Some countries grow surplus food to export for profit.
- Migration spreads food culture and increases demand for global products.
- Social media and advertising promote global food brands and fast food.
Environmental causes
Environmental causes
- Some regions have better climate, soil, or water for growing food.
- Climate change affects where crops grow best, shifting global food patterns.
- Some countries depend on imports due to poor local growing conditions.
Economic and social impacts
Economic and social impacts
- Local farmers may lose income if cheaper imports replace local food.
- Food security can improve with more supply, but local food production may decline.
- Local economies may suffer if food is mostly imported.
- Global food often includes fast food, which may lead to poor diets and health issues.
- Some people still stay malnourished if food is exported instead of shared locally.
Environmental impacts
Environmental impacts
- Modern industrial farming uses fertilisers and pesticides, harming soils and wildlife.
- Monocropping (growing one crop) reduces biodiversity and weakens ecosystems.
- Food miles increase pollution from transporting food long distances.
- Fossil fuels are burned during farming and transport, adding to climate change.
- Global food supply is often unsustainable and damages the environment long-term.
