A vision of urban food in 2020

Via Green Futures:

By 2020, two-thirds of the world will live in cities, often sprawling megalopolises. Growing populations will put further pressure on land already degraded by over-farming and desertificaion. Given that we are always only a few meals away from anarchy, how will we feed these cities?

There is a strong possibility that – two and a half centuries after the start of the industrial revolution – we will all become farmers again.

Every one of us will own a ‘farm in a box’, which will sit on our balcony, roof or next to a window. Advances in aeroponics – growing in a mist of nutrients, rather like in a rainforest – will give us emissions-neutral food at the heart of our cities.

These boxes would be supplemented by neighbourhood vertical farms housed in the redundant high-rise office blocks we no longer commute to, and the multi-storey carparks we no longer need. They will employ closed-loop systems, generating their own energy and harvesting and recycling rainwater. Front gardens, flat roofs and patches of wasteland will also become mini-market gardens, helping to green, cool and feed the city. (MORE)

Since governments and business will not make the required investments in energy infrastructure it will be left to individuals and local communities to cope with energy decline… Growing our own food is, of course, a method for capturing solar energy, i.e. it is a method for earning energy income. This energy in food can then be exchanged for forms of embodied energy such as items manufactured by others. For human beings, food is the ultimate currency.
