Edible cities: how urbanites can grow their own food
Living in a city often means being cut off from the source of one's food - unless you're lucky enough to have a garden.
But there are other ways to grow your own fruit and vegetables, even in the confines of a tiny flat. A new book, Edible Cities, celebrates the urban individuals who have embraced growing their own - be it through a balcony garden, or more unconventional means.
Many of them are adherents to the idea of 'permaculture' - sustainable agricultural practices that are based on nature's own processes.
In this extract from Edible Cities, three individuals from different parts of the world explain how they have brought nature into their homes.
