Planning for biodiversity in the urban fringe

Biodiversity near and within urban areas brings many benefits but its maintenance involves complex trade-offs between competing land uses. NERP ED researchers recently demonstrated how these trade-offs can be better described to facilitate more transparent, efficient and democratically derived urban planning. They used reserve design tools in a novel way to identify priority development sites. The approach is based on a synthesis of ecological, social and economic data. Then trade-offs between biodiversity conservation and other key development objectives were quantified. Other key development objectives included transport planning, flood risk and food production. And they demonstrated how all this can be done using a case study of changes in land use across the City of Wyndham, a local government west of Melbourne.

The process involved gathering data, identifying and weighting key values according to stakeholder preference, and modelling to produce visual representations of possible scenarios that have been optimised according to the chosen values.
