Water systems and disruptions: the 'old abnormal'?

Abstract

The dual nature of water – giver of life and massive disruptor – is not new. There is rarely one equilibrium state for a water system; there are multiple different states natural water systems cycle through. And human-induced changes to water systems, including through the use of technologies to modify and exploit them, and through climate change, further accentuate the opportunities for extreme disruptions to society. Human history is dotted with examples of challenges in managing water systems and disruptions. This year, parts of Australasia have seen widespread drought, massive fires, smoke pollution, ecological destruction, hail storms, cyclones and now a pandemic, COVID-19, protection from which requires adequate safe water and space for hygiene and limiting transmission. Our notions of time, space and connection to others and our environment, including water, have again come into focus as we search for a new equilibrium after this wave of disruptions – a ‘new normal’. But is this just a very human desire for stability amid the seeming chaos? Instead, do we instead need to get better at managing more appropriately through the ‘old abnormal’: the continuous variability, change and increasingly extreme events due in part to human modification and societal expansion across the planet?

This editorial paper provides a reflection on the moment we have found ourselves in at the beginning of 2020. It draws together insights from a range of water science and management challenges presented in the papers of this issue, in order to chart some positive ways for more appropriately navigating water systems and their future disruptions.
