Megadrought likelihood and its water resource impacts in Australia

这个跨学科项目计划组建一个由水文学家、气候科学家和水资源管理人员组成的世界级团队，调查十年一次到几十年一次的干旱（特大干旱）的历史和未来风险。尽管澳大利亚易受水资源短缺的影响，但澳大利亚持续特大干旱的可能性尚未得到评估。这导致了在未来气候变化下准备和适应特大干旱的能力不足。古气候重建和气候变化预测将首次用于约束未来的水文气候变率，提高澳大利亚水资源管理者的决策能力。

This interdisciplinary project plans to assemble a world-class team of hydrologists, climate scientists and water managers to investigate the history and future risk of decadal to multidecadal droughts (megadroughts). Despite Australia’s vulnerability to water scarcity, the likelihood of persistent megadroughts has not been assessed in Australia. This has resulted in inadequate capacity to prepare for and adapt to megadrought under future climate change. For the first time, palaeoclimate reconstructions and climate change projections will be used to constrain future hydroclimatic variability, advancing the decision-making capacity of Australian water resource managers.
