It's been about five years now since biofuel production started to get serious, and right at the outset there were concerns about it taking away land from food production. Well, there's a story in the news in the past couple of days on this topic:
"The time of cheap food prices is over," says Nestle chairman Peter Brabeck-Letmathe.He is highly critical of the rise in the production of bio-diesel, saying this puts pressure on food supplies by using land and water that would otherwise be used to grow crops for human or animal consumption."If no food was used for fuel, the prices would come down again - that is very clear," he says."We are now in a new world with a completely different level of food prices because of the direct link with fuel," he says.
Of course the important thing is that now the link between food and fuel is there, it's not going to go away very easily. So if you were thinking "well I'm not making it worse as I just burn normal diesel/petrol" then think again - every litre of fuel burned represents demand, and as there's no scope to increase oil supplies now, new demand is going to be met through biofuels. We're all responsible, and we all need to use less liquid fuel for travelling. Besides, ALL petrol and diesel in the UK includes a small percentage of biofuels now anyway...
But it's not just demand for liquid fuels that's the problem. The historic (and continuing) burning of fossil fuels is having an indirect effect on food prices through climate change. Now I know you can't link a specific weather event to climate change, but the 'stuck' jet stream which we've heard so much about recently is possibly partly due to reduced ice cover in the Arctic. While this has been soaking us in the UK, in the US it's brought drought conditions:
Maybe it's time to cycle or walk a bit more?US Agriculture Secretary Tom Vilsack has warned the worst drought in decades will result in higher crop prices.Mr Vilsack met President Barack Obama on Wednesday to discuss the US response to drought concerns, with little rain forecast to ease the crisis.By the end of June, 55% of the continental US was in a moderate to extreme drought, officials reported.Crops including corn and soybeans have been hit by the dry conditions, and several states have seen wildfires.Mr Vilsack announced in a press conference on Wednesday that the US Department of Agriculture had added 39 counties in eight states as "natural disaster areas", making farmers in those counties eligible for low-cost emergency loans....On Monday, a weekly US report said that just 31% of the corn crop and 34% of the soybean crop were in good to excellent shape.
