This in interesting its an initiative by Boris Johnson that will use spare plots of land in London to grow vegetables. Under the scheme not only spare plots of land but also other spaces such as roof tops and open areas around some of London’s famous landmarks could be used to grow vegetables. Some possible candidates are plots of land around the Tower of London, Marble Arch and the roof of the Hayward gallery. Boris will lead the way by planning some runner beans in a plot of land near City Hall and hopes that landowners will be encouraged to lend any spare plots to the campaign. The National Trust’s Grow Your Own Campaign will consider all plots of land including derelict building sites and supermarkets car parks and the trust itself has already pledged 1,000 plots of land from its own holdings. In addition to this Network Rail and British Waterway have also promised land.
