摘要

采用三种基础设施(灰色、软质和绿色)框架,我们研究了澳大利亚墨累-达令盆地水可用性和水质的主要风险。这些风险包括灌溉效率的提高,但对水流路径(特别是回流)的影响缺乏定量的了解,农田水坝和洪泛区收获的增长,以及不可持续的盐度管理。减轻这些风险的关键是对水流的计量、监测和审计,证据与分析之间的有效联系,以及为公共利益行事的决策者的问责制。我们认为,这些方法需要得到创新风险评估的支持,这些评估符合多边开发银行计划的目的,其中“谁、什么、何时、何地”是根据人类行为带来的累积、系统性和级联风险进行评估的。

The three-infrastructures framework and water risks in the Murray-Darling Basin, Australia
ABSTRACT Using a three-infrastructures (grey, soft, and green) framework, we examined key risks to water availability and quality in the Murray-Darling Basin, Australia. These risks include increased irrigation efficiency, without a quantitative knowledge of the impact on water flow pathways, particularly return flows, growth in farm dams and floodplain harvesting, and unsustainable management of salinity. Critical to mitigating these risks are the metering, monitoring, and auditing of water flows, effective linkages between evidence and analysis, and accountability of decision-makers operating in the public interest. We contend that these approaches need to be supported by innovative risk assessments, which are fit-for-purpose under the MDB Plan, wherein the ‘who, what, when and where’ are assessed in relation to cumulative, systemic, and cascading risks from human actions.

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.
