'This June as part of London Festival of Architecture 2008, City Hall will host a conference to tackle one of the biggest issues we will face in the coming years: Where will London get its food from? ...

'Ben Reynolds, from organisers London Food Link,[2] believes the timing is crucial: "Set against rising food prices and increasing pressures to tackle climate change, London seriously needs to consider putting aside more space for growing food. Not only will this help future-proof against food shortages and preserve the capital’s open space, but it will also educate and improve the health of Londoners and reduce the distance that London’s food has travelled*." ...'

I think that a fundamental motiviation for projects like this is the 'future-proofing' aspect. In uncertain times, you need Plans B, C and D to ensure the population aren't going to go short of food.

* Recent research (Weber and Matthews) in the USA suggests that the final journey to our plates accounts for about 10% of the climate impact of food (although more for air-freight). The climate change impacts of animal farming account for over 50% of the carbon footprint of the typical British diet.
