Rooftop Agriculture - A climate change perspective

Elaborated by Mariëlle Dubbeling and Edouard Massonneau, RUAF Foundation (2012)
Rooftop agriculture is the production of fresh vegetables, herbs, fruits, edible flowers and possibly some small animals on rooftops for local consumption. Productive green roofs combine food production with ecological sustainability, such as reduced rainwater run-off, temperature benefits such as potential reduction of heating and cooling requirements (resulting in reduced emissions), biodiversity, improved aesthetic value and air quality. Most green roofs  designed by architects however do not give attention to the productive potential of the roof tops, whereas green roofs developed by Community Based Organisations and Non-Governmental Organisations often take this as the starting point.
