As flagged in the Weekly Times, the Murray-Darling Basin Authority has released the list of Sustainable Diversion Limit (SDL) adjustment projects. These projects have the ability, through complex modelling, to reduce the total water recovery target.
While these projects support numerical targets, at its core, the Basin Plan aims to establish a sustainable and long-term adaptive management framework for the Basin water resources and to optimise social, economic and environmental outcomes arising from the use of those water resources. Maintaining focus on these core objectives has been an ongoing struggle in the implementation of the Basin Plan.
As this recent article in The Conversation highlights, we are dealing with a highly complex system, where flow restoration is only a small part of delivering ongoing benefits for all. Given this complexity, the critical objective of the Basin Plan, to establish a sustainable and long-term adaptive management framework, is fundamental to success in ensuring a healthy and working Murray-Darling Basin with optimised social, economic and environmental outcomes.
The MDB Authority has released the list of Sustainable Diversion Limit adjustment projects, which use regulators, pumps, levees, high flows and even changes to river and storage management to enable less water to achieve the same environmental outcomes.
