Mosaic Insights are currently engaged by a Victorian public agency to set targets for the urban cooling (and hence tree canopy cover) for a significant urban development in an emerging growth corridor of Melbourne. The intention is that the outcomes from this project will feed into the first evidence-based, heat-related urban greening targets in Victoria and NSW.
The project will be an exemplar of urban development in water, energy, housing affordability, ecology, indigenous heritage, transport and waste. One of the central elements will be the urban forest and open space network at the site—collectively referred to as green infrastructure. The client has developed a range of vision statements, strategic direction statements, objectives and targets for the project’s long-term goals, which include dedicated objectives and targets relating to community resilience, employment and active transport.
Mosaic Insights developed draft targets for urban greening based on urban microclimate modelling and synthesis of the outputs from the broader R&D program. The targets include:
The collaborative approach that the client has adopted provides for testing and challenge of the innovations as they are developed.
Mosaic Insights and Natural Capital Economics are now reviewing the feasibility of these targets through detailed analysis and feasibility assessment. The work will include consideration of the challenges of creating high levels of urban forest canopy cover in urban developments and analysis of complementary cooling interventions (both greening and built form-related). The benefits and costs of the urban greening strategies will be assessed to inform the business case.
The outputs from this project will influence green infrastructure targets across the Melbourne growth areas.
