Over the coming weeks I am going to write a series of posts about technology and food production. Food is a topic that I have been interested in from a sociological perspective for several years, and I have a few topics that I would like to address, from GM, to regulation, sustainability and organic alternatives.

Technology plays a huge part in food production. If we just think about GM products, transport issues, industrial farming techniques and globalization in generic terms, it becomes immediately apparent that this sector is the largest in the world. According to these statistics agriculture accounts for between 14 and 24% of all global emissions of CO2, and 19 to 29% of total greenhouse pollutant emissions. An interesting point here is that in the so-called developed countries post-farm emissions are very high, so in the UK for example 50% of these emissions are produced after the food has left the farm, presumably through processing and transport techniques.

But it seems to me that processing is where the money is. According to Forbes, Pepsi for example made almost $45 billion in 2009 and Nestle’ made $110 billion, and these profits only refer to US sales. This year the sector is one of the very few that is still growing.

If you look at vegetables though they make less money. Dole is the largest producer of fruits and vegetables in the world, but in the same year made only $6.8 billion, leading me to conclude that the profit is in the processing and not in the actual foodstuffs themselves.

And this leads on to the question of what goes into these products. The answer is, largely, genetically modified (GM) organisms.

Yes if we look at the statistics that the US Department of Agriculture publish, we find the following:

93% of soybeans grown in the USA are GM

90% of all corn produced in the US is GM

95% of US sugar beat is GM

40% of all cropland in the US is used for Monsanto (the largest GM seed producer) production

40% of all global GM crops are produced in the US

35% of all the corn grown in the world is GM

81% of all the soybeans grown in the world are GM

I take some of my information from here, the Organic Consumers Association website and the rest from US government sources.

So as you can see it is big business. It is estimated that 70% of all the foods in our supermarkets contains GM organisms. 16.5 million people work in the industry in the US and it accounts for more than 10% of GDP.

And it is not just plants, there is a request for FDA approval for GM salmon. It grows at twice the speed of regular salmon.

The GM salmon, produced by AquaBounty Technologies contains a gene from a Chinook salmon that produces a growth hormone, and a genetic “on-switch” from an ocean pout (an eel-like fish) that keeps the growth hormone pumping out year round. The company state that GM salmon will consume 25 percent less feed, half of which can be plant protein.

Oh and in the US none of this is labeled, although currently 64 other countries do require labeling.

GM organisms have been found in many countries that do not allow their production however, Mexico comes to mind as the closest example to the USA. Seeds have blown across the borders from the US, over the mountains, across the seas, possibly even from Brazil and Argentina and landed and grown. Not to mention imports of contaminated produce. Read the scientific report here.

Corn is socially extremely important in Mexico, its cultivation all started there, and this contamination has caused some serious soul searching. In a related issue GM companies are currently trying to get permission for huge plantations in Mexico, as this Reuters article explains. We await the court’s decision.

For now I stop here, I think that is enough food for thought for this week (groan). Next week I shall delve once more into the murky waters of the global food industry however, and who knows what we might find. Comments please below.
