Comment on sustainable salinity management in ‘the three-infrastructures framework and water risks in the Murray-Darling Basin, Australia’ by Williams et al. (2022)
ABSTRACTIn their recent paper, Williams et al. (2022) evaluated salinity management in the Murray-Darling Basin (MDB) as ‘unsustainable’, and a risk to water availability and quality in the Basin. However, this evaluation was weakened first by a failure to analyse the Basin salinity strategies of the last thirty-five years, noting that these have led to Basin salinity target being met since 2010; and second to not providing Basin-specific data to support their evaluation. Contrary to Williams et al. comments, existing evidence indicates that infrastructure intended to improve water use efficiency (e.g. salt leaching, salt disposal basins) will generally reduce stream salinity. The requirement for a leaching efficiency means that there is a lower limit to water use efficiency improvements, but this is unlikely itself to be a major risk. We agree that the changes that have occurred over the last twenty years would warrant a review of salt storage options in the MDB that better matches future needs.KEYWORDS: Murray Basinsalinitysalt disposalstream salinitysaline ecosystems AcknowledgementsThe authors would like thank Asitha Katupitiya, Acting General Manager, Sustainable Diversion Limit Adjustment Mechanism, River Management Portfolio, Murray–Darling Basin Authority, Canberra for his comments on earlier draft of the manuscript.

期刊介绍:
The Australasian Journal of Water Resources ( AJWR) is a multi-disciplinary regional journal dedicated to scholarship, professional practice and discussion on water resources planning, management and policy. Its primary geographic focus is on Australia, New Zealand and the Pacific Islands. Papers from outside this region will also be welcomed if they contribute to an understanding of water resources issues in the region. Such contributions could be due to innovations applicable to the Australasian water community, or where clear linkages between studies in other parts of the world are linked to important issues or water planning, management, development and policy challenges in Australasia. These could include papers on global issues where Australasian impacts are clearly identified.
