Federated Farmers’ Hawkes Bay president Will Foley asks, who are the denialists now?
RadioLIVE recently ran an online poll asking its listeners if they were frightened of climate change. To the shock of host Marcus Lush, two-thirds of respondents apparently said no, they’re not. I would have said yes.
As some groups are cock-a-hoop over tough consent conditions imposed on the Ruataniwha water storage scheme and others think them lax, you have to wonder if this public climate weariness has spread to them too.
What it all means for the viability of Ruataniwha won’t be known until the 700-page decision is crunched but what I know is this. If the scheme does not progress it won’t affect Green Party MP’s in their air conditioned offices or the paid Wellington staff at Forest & Bird. They don’t have to worry about the El Nino being talked about for spring. They don’t have to watch our region increasingly turn into a retirement village while our young drift to Auckland or Australia. They don’t have to deal with crime since Hawke’s Bay bucked the national trend last year.
I cannot understand why some are so hell-bent on derailing a scheme, which gives Hawke’s Bay its best shot at adapting to a changing climate. Federated Farmers hosted Dr Russel Norman at the South Island’s Opuha water storage scheme a few years ago. Memories seem short unless you are a politician.
With a medium level of confidence the climate experts say that average rainfall on the east coast will decrease this century. This will lead to lower flows of the Makaroro River, Waipawa and Tukituki Rivers. The International Panel on Climate Change warns that by 2040, the East Coast can expect to double or even triple the time spent in drought. This is our future unless we adapt and that means new pastures, crops, technologies and even animals. Above all, adaption means storing water like that proposed by Ruataniwha.
I will be blunt to make a point; the shit in the Tukituki during summer low flows has mostly been human. Up to 70 percent of phosphorous loading during low flows had come from the wastewater plants of Waipukurau, Waipawa, Otane and Takapau. That’s thankfully changing with upgrades in hand while the allocation regime will put more water into the Tukituki during summer.
Ruataniwha could do more. It could put a quarter of a billion dollars into those towns each year providing councils with the means to meet increasing drinking water standards. This proves that the environment and economy are flipsides of the same coin. If there’s no scheme, there’s no dam supported flushing and little additional money to upgrade existing plant. Can anyone tell me the environmental win in that?
Is it just me or has the media and Ruataniwha opponents overlooked the IPCC’s warning that New Zealand is underprepared for a changing climate. If anything, there seems to be outright denial since these groups seem to believe our rivers in 2040 will be exactly as they were in 2014. It is not like the Hawke’s Bay Regional Investment Company got a muppet to look into climate issues and Ruataniwha either. Victoria University’s Dr James Renwick happens to be an international expert in this field.
While dryland places like North Otago have been averaging twice their normal rainfall over the past five years, in the same timeframe, we’ve had three droughts and it is dragging Hawke’s Bay down. Out of 67 councils in the last census, Hastings District slipped nine spots to 30th spot, Napier went back one to 31st while Central Hawke’s Bay District dropped to 58th – losing 1.8 percent of its usually resident population.
If Ruataniwha’s consents are so tough they are Clayton’s ones, then it will be a Pyrrhic victory for the environment. As the climate warms so will the waterways while the volume going into them drops. While that’s great for algae it doesn’t sound so flash for introduced trout or native fish and birds.
While we can expect less intense rainfall we can store what falls and that’s the beauty of Ruataniwha and the secret recipe of our economy; just add water.
So is Ruataniwha perfect, probably not, but what is? Do I have the information to make an informed investment decision? That now hinges on the consent conditions attached by the Board of Inquiry. Yet debating the principle of storing water, given towns and cities do it, is a bit like debating the wisdom of sunblock, dumb.
If we accept the climate is changing then we need to store water and adapt how we currently do things. If you deny the climate will ever change then I guess you won’t be at the National Aquarium of NZ on 6 May, where NIWA’s Dr Andrew Tait is talking at 730pm on The Climate and Weather of Hawke’s Bay.
New Zealand makes a tiny contribution to green house gases.
No matter how hard we try to reduce emissions, we are at the mercy of other countries whose emissions are much greater.
We can continue to do our bit but we must also prepare to adapt to whatever nature throws at us.
If, as is predicted, parts of New Zealand will be hotter and drier, then water storage schemes like Ruataniwha which will enable irrigation and maintain minimum flows in rivers, are not just sensible, the economic, environmental and social benefits they provide.
