Urban Agricultural Heritage [PDF ebook] 

Urban gardening and agriculture have become important elements of sustainable urban planning in the context of persistent urbanization amid limited resources. However, a consideration of the cultural-historical dimension has been lacking up to now. The editors present the first comprehensive outline of traditional forms of food production in cities to help preserve this valuable knowledge. On the basis of current research findings, they develop new perspectives and guidelines for recognizing traditional food production systems as an aspect of cultural heritage and for dealing with urban agriculture worldwide.
