Megadrought likelihood and its water resource impacts in Australia
Grant number: LP150100062 | Funding period: 2016 - 2020
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.
