We are no longer updating the Research Digest. All content remains.
The Permaculture Research Digest has summaries of newly published permaculture-related research. All items are hyper-linked to the original publication.
The 'January 2013' archive contains 60 items published in 2012.
Items marked with a # have restricted public access, although abstracts are freely available.
Urban rooftop farming favours local food production. Although rooftop
farming is perceived as a sustainable system, there is a lack of
quantitative studies. Researchers in a community
rooftop garden in Bologna, Italy, grew lettuce, tomato, chilli pepper, eggplant, melon and watermelon.
Data was analysed by life cycle assessment for environmental and
economic performance. Eggplants and tomatoes showed the best environmental
performances of about 74 g CO2 per kg. Eggplant production in soil was cheapest at 0.13 € per kg.
