A lecture at the Royal Society of Edinburgh on 9th February 2015
Tom Benton is Global Food Security Champion He made a number of critical points on world growth and how and if it could be sustainable
- There are 805 million in the world hungry; there are 1 million people in the UK in food poverty
- All of us eat the wrong food. 2/3 of the food eaten is wheat, rice and maize; if we include sugar, barley, soya, palm oil and potato we get up to 86%
- The world population will increase from the current 7 billion to 10 billion by 2050
- Food for Europe comes through the Suez Canal – an interruption in flow and Europe would be in crisis – there aren’t enough ships to go via the Cape
- The World will be 4* hotter; it’s not the average temperature that matters to growing plants it’s the maximums which could 6* or 7* above the average – at 35*C maize will not grow
- 70% of water used for agriculture; 1 kg meat takes 10/12 tons of water for production; a green bean from Kenya takes 1 gallon of water
- Eat local food , it saves water and carbon
- After continuous increase in crop yields now starting to drop off
- Need to reduce demand for food
- 1/3 of food wasted – 3 for 1 but best by today.
- The need for supermarkets to always have food available requires that they have 200% resilience
- Our food laws have stopped recycling of waste
- Health cost is £2,500 per person per year in the UK
- 50% of Chinese heading for diabetes
- In 2050 we will be eating more than the World has produced so far; needed 120% more water 40% more crop land 10% less forest
- Loss of biodiversity
- Agriculture produces more carbon than cars
- A plea for more horticultural research
- Food sales dominated by Marketing and supermarkets. Remember that supermarkets provide the food that we want to buy. The answer is a change in us not the supermarkets – if we change our eating habits then supermarkets will change what they sell. A bottom up approach is needed
- During WW2 we got it right
