A Green Factor Tool for Enhanced Greening in Melbourne’s Urban Areas.
As cities increase in size and density, the ecosystem services supplied by urban greenery and green infrastructure are increasingly vital for sustainable, liveable urban areas. However, retaining and maximising urban greenery in densifying cities is challenging. Judy Bush assisted in the development of the City of Melbourne’s Green Factor Tool – a way of assessing the green infrastructure merits of building development applications in the private realm. This new paper looks at the process and contribution of transdisciplinary experts and local research into the design of the tool, and the role of urban planning in retaining and maximizing urban green spaces.

Estimates from 100 global cities shows the cooling potential or irrigating green spaces
PhD candidate Paul Cheung, A/Prof. Steve Livesley and Dr Kerry Nice have investigated the potential of irrigating urban green spaces to mitigate heat stress in cities. They used a systematic literature review combined with empirical modelling to determine the cooling potential of irrigating green spaces in 100 global cities with arid, temperate or continental climates. They found most of the cities (91 out of 100) will receive a cooling benefit from irrigation with the greatest cooling potential in arid cities.

The right way to use old coffee in your garden
Horticulturalist and Burnley alumni Sara Hardgrove is featured in this ABC Everyday article where she discusses the downside of using raw coffee grounds directly on plants. Sara explains that composting is key to transforming coffee grounds into a beneficial soil conditioner.

PROJECT UPDATE
Direct seeding of green roofs shows potential for biodiversity, aesthetic and cost benefits
PhD candidate Zahra Saraeian is investigating a novel approach to establishing green roof vegetation – the direct seeding of Australian annual flowering plants for biodiversity and the aesthetic value of their colourful flowers. Establishing an annual plant palette by sowing seeds allows a large area to be covered with little labour, reducing costs considerably. These plant communities also have the potential to be self-sustaining through recruitment. Zahra’s aim is to develop an attractive, resilient plant palette of Australian annual species suitable for green roofs in Mediterranean-like climates.
We also welcome Honours student Surui Ye who will soon be joining the project and will focus on additional elements of direct seeding of green roofs.
Zahra’s project is funded by Hort Innovation through their Green Cities Fund as part of the project Researching the benefits of demonstration green roofs across Australia and is supervised by Prof. Nick Williams and Dr Claire Farrell.
