Australia should brace itself for potential “megadroughts” lasting over 20 years, as indicated by new research from the Australian National University. These prolonged periods of below-average rainfall have occurred in the country over the past millennia and are expected to reoccur every 150 to 1,000 years.
Dr. Georgy Falster, who led the research, emphasized the importance of preparing for future megadroughts, stating that while they have not been officially recorded due to limited observational rainfall records, the likelihood of one occurring in the near future is high. Falster stressed the need for robust water management plans, support for drought-prone rural communities, and environmental protection measures to mitigate the severe impacts of a megadrought.
The study highlights the urgency of reducing greenhouse gas emissions to lessen the severity of future droughts. The Australian government is currently working on a national climate change adaptation plan and risk assessment to better prepare for the increasing risks posed by climate change.
Jenny McAllister, assistant minister for climate change, affirmed the government’s commitment to reducing emissions while also taking steps to protect the economy, society, and natural environment from the inevitable changes brought on by global heating. With the potential for megadroughts looming, Australia must heed the warnings of researchers and take proactive measures to safeguard against the devastating effects of prolonged droughts.
