Assessing water availability under climate change

Assessing water availability under climate change

The effect of drought on water availability is receiving an increased amount of attention as we head into a future where the impacts of climate change are already being felt.

The level of risk to New Zealand from restricted drinking water availability under “as yet unexperienced droughts” emerged as one of the priority questions and knowledge gaps from the Climate Change and Drought Dialogues. This gap in knowledge forms the basis of the research conducted by Tonkin + Taylor scientists, Wageed Kamish, Peter Cochrane and John Hansford in their report for the Deep South Challenge, “Water availability under climate change”. The full report discusses the likely incidence of future multi-regional drought, the likely nationwide spatial pattern of expected change in drought incidence and the level of risk we are likely to face in relation to drinking water availability in times of drought.

In this video, the report’s lead author, Wageed Kamish explains how this research identifies an approach that allows regional councils to assess their water availability in this time of changing climate, for the very first time.
