Roof top gardens in Italy (#journal)

Techniques and crops for efficient rooftop gardens in Bologna, Italy

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.
