"A speech by HRH The Prince of Wales to the Future for Food Conference, Georgetown University, Washington DC"
This is the context we find ourselves in and it is set against the backdrop of a system heavily dependent upon fossil fuels and other forms of diminishing natural capital – mineral fertilizers and so on. Most forms of industrialized agriculture now have an umbilical dependency on oil, natural gas and other non-renewable resources. One study I have read estimates that a person today on a typical Western diet is, in effect, consuming nearly a U.S. gallon of diesel every day! And when you consider that in the past decade the cost of artificial nitrogen fertilizers has gone up fourfold and the cost of potash three times, you start to see how uncomfortable the future could become if we do not wean ourselves off our dependency. And that’s not even counting the impact of higher fuel prices on the other costs of production – transport and processing – all of which are passed on to the consumer. It is indeed a vicious circle.
Then add the supply of land into the equation – where do we grow all of the extra plants or graze all that extra stock when urban expansion is such a pressure? Here in the United States I am told that one acre is lost to development every minute of every day – which means that since 1982 an area the size of Indiana has been built over – though that is small fry compared with what is happening in places like India where, somehow, they have to find a way of housing another three hundred million people in the next thirty years. But on top of this is the very real problem of soil erosion.
Again, in the U.S., soil is being washed away ten times faster than the Earth can replenish it, and it is happening forty times faster in China and India. Twenty-two thousand square miles of arable land is turning into desert every year and, all told, it appears a quarter of the world’s farmland, two billion acres, is degraded.
Given these pressures, it seems likely we will have to grow plants in more difficult terrain. But the only sustainable way to do that will be by increasing the long term fertility of the soil, because, as I say, achieving increased production using imported, non-renewable inputs is simply not sustainable.
