So I read this piece to check that was what Bronwen Maddox meant. Great (not) was my surprise to find that this is a different sense of "unsustainable":
European Union misses rare opportunity to change farming rules | Bronwen Maddox: World Briefing - Times Online
If Europe is going to have farming, then it should be efficient, and produce food as cheaply as possible.
Big industrial farms, that's what's sustainable. When locusts move on, they leave nothing behind

Big industrial farms, that's what's sustainable
But they're not, that's what's sad about this. Big farms relying on petroleum-fuelled large machinery to spread large amounts of petroleum-derived fertilzers and sundry other chemicals to help grow GM-industrial crops which are then shipped halfway around the world is simply not a practice that is going to survive $200 - 300 oil/barrel.
It's the very farms and practices they intend to destroy that will sustain us. This is not just homogenisation for corporate benefit, this is a vindictive short-termist attempt to reduce the viability of european food production through the 21st century. keep to the Fen Causeway
