Surrounded by open and green spaces, Melbourne was once known as the heart of the Garden State. However, we are undergoing unprecedented growth and change. Our city is facing significant challenges with climate change, population growth and densification. These challenges are leading to impacts across our city as we move further away from natural landscapes to hard infrastructure. Melbourne is renowned for its heatwaves and unpredictable weather. As we begin to feel the effects of population growth and climate change, our need for urban adaptability is more crucial than ever. Roofs in the City of Melbourne cover 880 hectares of our municipality, more than five times the size of Royal Park, the largest park in the area. By investing in urban greening projects and using these underutilised roofs, we can all help transform our city back into the green heart of Victoria. The Valuing Green Guide, based on the work of Victoria University and the University of Melbourne, explores and summarises essential research into the value of green roofs, walls and façades in Melbourne.
