Wai is life. It is a critical resource that we rely on for our survival, cultural and environmental health.

Wai enables communities to be resilient and provide for their social, economic, environmental and cultural wellbeing, as well as the health of generations to come.
The impacts of climate change on our water will continue to grow
Water and climate change The long-term shift in global or regional climate patterns attributed directly or indirectly to human activity. GHG’s emitted into the atmosphere through human activity alter the composition of the global atmosphere, causing rising global temperatures and changing weather patterns in addition to natural climate variability. are inextricably linked. The impacts of a changing climate on water in Tāmaki Makaurau is already apparent.
Variability in rainfall patterns already reduces Auckland’s water supply and contributes to drought. At the same time, more frequent storms contribute to more frequent floods and coastal inundation Flooding of normally dry, low-lying coastal land. This is primarily caused by severe weather events along the coasts, estuaries, and adjoining rivers..
As our climate changes, these events will increase in severity. Changes in the volume and location of rainfall will mean we have to rethink how we manage water and deal with issues from flooding and coastal inundation, to drought and scarcity.
Water quality will also be impacted by climate change. Higher temperatures and lower water flows have the potential to increase the growth of algae and other pest species within our water environments.
Conversely, increased storm events could displace greater qualities of sediment and other contaminants from our waterways into the marine environment.
We need to support and increase resilience in our water cycle
Aucklanders have told us that they want the mauri Life principle, life force, vital essence. The essential quality and vitality of a being or entity. of water to be protected and enhanced.
Auckland Council family has responded, for example, through the water quality targeted rate and exploration of alternative supply options.
However, it is important to recognise that the ability of these interventions to improve water outcomes for Aucklanders is significantly influenced by the projected impacts of climate change.
Our response needs to take an adaptive, holistic approach Consideration of a whole system or all parts, functions, parties or principles related to a topic area, rather than isolated parts. For example, a holistic approach to medicine takes a broad ‘whole of person’ approach, rather than focusing on treatment of individual symptoms. while being grounded by the climate change effects that are projected for the region.
We need to make better use of what we have and ensure that resilience is built into the region’s natural water cycle The continuous movement of water on, above, and below the surface of the earth, through processes such as evaporation, precipitation, run-off, and infiltration., at every level.
Individual responses could include enabling the capture and reuse of water at a household scale.

Our water response also needs to recognise the potential opportunities for carbon capture within the natural environment.
