As China announces a moratorium on bio fuel production due to the rising price of food (
Times ), the BBC has been investigating the rising cost of food in the UK (
Today programme ).
We take cheap food from the supermarket for granted in this country. On the Radio this morning I heard a statistic that whereas in 1980 something we used to somthing like 16-26% of our income on food, we now spend only 8%. With poorer crop yields worldwide due to extreme weather (droughts & floods), farmers in many countries switching to bio fuels (e.g. Brazil & US), an increase in demand from emergent economies such as China, and the continued growth of the world population, however, this situation may be about to change.
Commentators say that fluctuations in the food market historically quite common, with sudden peaks settling down as production rises to match demand. It was predicted as far back as the 18th Century that we would soon run out of food. This was abetted by the development of intensive agriculture and nitrogen fertilisers, without which we could only sustain about a third of the current world population. Now though, we are running out of land.
The problem is further compounded by climate change, already thought to be responsible for the weather damaging current production and set to get have a far greater impact as the carbon emissions of the last 40 years catch up with us. In a vicious cycle, lack of land could lead to further deforestation of the last remaining great forests in develop ping countries for food and fuel, causes even more climate chaos.
As with the looming energy/ peak oil crisis, some believe there is a magic solution in GM crops, the edible equivalent of nuclear power stations. Like nuclear power though, I believe that this 'comforting' thought is delusional. Even if we engineer plants which produce greater yields and are more disease resistant, we would need more resources grow them and new diseases would develop. Furthermore, the practice of mono cropping is an extremely destructive of delicate soil systems which are intricately linked into other ecosystems, essential to the sustenance of life on this planet. This leads to desertification.
So how about some pragmatic answers?
One thing which is imperative is that we need to avoid Climate Chaos at all costs.
Then, we may also need to accept that some of our disposable income may need to be redirected back to feeding ourselves.
Or better still...
Start growing your own food. What use is an ornamental garden? There's even a book you can buy call
Food not Lawns. You can encourage bio-diversity through inter-cropping and more small scale localised food production. Permaculture is a good place to look for practical advice on how to become self sustainable while working in harmony with natural systems.
We could also try eating less meat. Not only is meat more expensive than vegetables, it takes up more resources and produces more carbon. According to
The Vegan Society , 1/3 of the grain we grow is fed to farm animals. 25% of the world's surface is given over to grazing cattle. The fossil energy input needed to produce a day's food for a meat eater is about 34,000 calories. For a vegetarian it is only about 20,000 and for a Vegan only 10,000. In terms of water, the figures stand at 15,000, 5,000 and 1,500 respectively. Farm animals also produce large amounts of waste which pollute rivers and streams.
Now I'm not even a vegetarian, let alone vegan, but I have been cutting down on my meat consumption considerably in the last few years. I don't buy meat very often, hardly at all anymore. Speaking to a vegan at the weekend though, he pointed out that even allowing other people to feed you it encourages higher consumption. As for the vegetables, I started with a patch at the begging of this year and am considering an allotment next year if I'm still living here. I intend to design future projects with permaculture in mind. I could probably eat a bit less mind you, I am a bit of an eating machine...
