- The future of food
- Climate change
- India - Every 1 degree increase in temp, 5-10% decrease in yields
- UK - Extreme events impact food production
- Temperate climates
- Consequences of climate change unlikely to be as extreme, but effects on agriculture already clear
- Leckford Estate
- Waitrose farm
- 2007-08 - volatility
- Weather becoming more unpredictable for farmers
- Leckford Estate
- Consequences of climate change unlikely to be as extreme, but effects on agriculture already clear
- Temperate climates
- By 2020, several African countries will suffer up to 50% reduction in yields
- Kenya
- Droughts have become 4 times more common in the last 25 years
- 3rd failed harvest in a row
- Masai - Rift Valley, cattle are dying
- Kenya
- Half the world's population could endure a climate induced crisis by the end of the century
- Australia, Argentina and the USA are drought prone areas that export large quantities of food across the globe
- Natural resources
- Oil
- Used in food production for transportation, fuel, fertilisers, pesticides, processing & packaging
- Cuba
- Cheap oil from Eastern Bloc, fuel thirsty agriculture, collapse of USSR = oil reduced
- Now, self sufficient agriculture
- Every bit of land used to maximise production
- Biofuels
- Chattisgarh, India
- Jatropha - used in biofuels, if animals eat = death
- Local farmers' crops uprooted by government and now rely on food handouts
- Norfolk
- Largest sugar refinery in Europe
- Must make sure biofuels for the rich are at no expense of the poor
- Chattisgarh, India
- Water
- Punjab, India
- Intensive agriculture drained the state dry
- Drilling deeper to irrigate land = poorer water quality which is less effective for irrigation
- Grimsby
- Processing centre for other countries' fish
- 80% of the UK's fish species are under threat
- Punjab, India
- Oil
- Last 2 years - dramatic spikes in food prices. Riots on 3 continents - future wars will be over food and water instead of oil and territory.
- Rising population - doubled over last 40 years - almost 7 billion
- Local markets replaced by global, food has become a commodity
- 2000 - number of hungry people in the world stopped declining and began increasing
- Food security issue affects all - not just developing countries.
- Carry on farming with today's techniques & yield levels - by 2050 would need to double amount of food we grow. Would need farming land the size of Brazil. Finite amount of land will not support this,
