Landshare was the one of the “big concepts” started by Hugh Fearnley-Whittingstall from River Cottage in Dorset a couple of years ago. The idea is that River Cottage acts as hub to put people who have surplus or unused land together with people who will tend it and grow things on it for mutual benefit. So far they have 58,396 members (20th Feb) across the UK. But it didn't just stop there. Hugh recenty launched Fish Fight – to prevent or reduce the discarding of fish which are “over quota”. Currently 648,000 people have signed up for that one.
LandShare Australia, which is about as far as you can get from Dorset, is just starting up and will be using Hugh’s principles.
