Urban practitioner’s ‘toolbox’ of interventions
An intervention-based cost-benefit assessment framework
As part of the Local Action Project, a framework for the assessment of costs and benefits of catchment management programmes in urban landscapes has been developed. Information gathered has been used to develop a framework for the quantification of benefits resulting from interventions designed to enhance ecosystem service provision or mitigate loss of provision in urban landscapes. This framework is scalable, to ensure that it can be applied to a broad spectrum of urban situations, and includes a widely applicable series of metrics that allow all potential benefits to be measured (whether monetisable value or not).
The list of interventions was compiled by reviewing existing typologies of green infrastructure components and sustainable drainage systems. They were categorised into ‘existing assets’ and ‘interventions’ based on the likelihood of being implemented as a new feature.
