Edible Roof

EDIBLE ROOF: A manual for building and operating a productive roof garden in Hong Kong. Many city dwellers have a strong desire to grow their own vegetables and contribute to a more sustainable urban life style, but lack the space to do so.   The Division of Landscape Architecture has run a two year KE project to develop a comprehensive manual to help interested individuals and community groups in Hong Kong create and run sustainable edible gardens on their building roofs, with the minimum of effort and expense.

Growing plants on a roof can be very different from ground level urban farming and the manual addresses the unique environmental and technical challenges of gardening on a roof.  Whether people are activating an unutilized grey roof space to build a completely new edible garden or converting an existing ornamental green roof to vegetable production, the manual provides a step-by-step guide to undertaking the whole project and as a technical reference for tackling specific issues.  The approaches and techniques described can be applied to almost any roof space, from a few humble planters on a balcony to an extensive productive garden across a large scale industrial roof deck.

The manual is based on the HKU Edible Roof that was constructed on the Runme Shaw Building as a research project by a team from the Division of Landscape Architecture, and is now operated under the HKU Urban Farming initiative. The manual is currently in final stages of production and should be published early in 2015.  The information generated has already been used to help a number of commercial and institutional organizations develop their own Edible Roofs.
