Introduction to sustainability 🌿
- Sustainability: How long terrestrial food systems can last and how effective they are.
- Key factors: Dependence on agriculture & value of agricultural output.
Ledcs vs. medcs🌍
- LEDCs: Less Economically Developed Countries.
- Agriculture: Small-scale, labour-intensive, subsistence-based.
- Vulnerabilities: Dependent on few crops, affected by price fluctuations & poor harvests.
- Example: Tea, coffee, and cocoa - prices are controlled by MEDCs.
- Challenge: Increasing influence from Multinational Companies (MNCs) through land ownership, marketing control, input supply, and crop production.
- Limitation: Difficult to adapt fully to external pressures; new methods can result in increased poverty and environmental harm.
- MEDCs: More Economically Developed Countries.
- Agriculture: Resembles manufacturing, capital-intensive, large-scale, and market-orientated.
- Government role is critical.
Industrialization of agriculture 🚜
- Mechanization:
- Using machines (like tractors) to improve farming efficiency.
- Not suited everywhere, e.g., not for terraced paddy fields in South-East Asia.
- Fun Fact: In the USA's Great Plains, machines outnumber farm workers!
- Fossil Fuel Use:
- Linked to agriculture's industrialization.
- "Food miles": Measures food's journey from production to consumption.
- Wowza: An MEDC festive meal travels roughly 24,000 miles!
Dietary shifts 🍗
- Cereal-based diets common in poorer countries.
- Richer nations opt for mixed diets, with a surge in chicken consumption.
- Dietary Tip: Westerners prefer lean meat, while Asians and Africans enjoy darker meat. Organic and free-range options are becoming popular.
Water consumption in Agriculture 💧
- 70% of global water use is by agriculture.
- Transition to meat and dairy-based diets needs more water.
- Thirsty Fact: 500g of beef needs 7,500 liters of water! Compare that to wheat which needs just 650 liters.
