Some Facts about water

  1. A recent OECD survey (2014) measured the cleanliness of all major rivers that flow through farmland in OECD countries. Of the three New Zealand rivers measured, where did the Clutha, Waitaki and Waikato, respectively, place?

Answer:  Of all major rivers in the developed world that flow through farmland, the OECD found Clutha rated 1st, the Waitaki 2nd and the Waikato 4th for cleanliness.

  1. Compared with other developed countries’ major rivers, the OECD study found New Zealand’s three longest rivers contained what levels of nitrates and total phosphorous, respectively?

Answer:  Our three longest rivers were found to have very low levels of nitrates, and relatively low levels of total phosphorus.

  1. The latest Commission for the Environment report said, what percentage of New Zealand rivers are getting cleaner?

Answer:  90% of our rivers are getting cleaner. There are river care and land care groups on all main and many small rivers across New Zealand. They’re spending millions of dollars to improve water quality. They include farmers, Fonterra, Dairy NZ, NZ Beef and Lamb, Landcare NZ, Federated Farmers, Iwi, fertilizer companies, universities, and regional councils.

  1. How many of New Zealand’s 1000 rivers did the Parliamentary Commissioner for the Environment classify very poor for cleanliness?

Answer: Only 17 of our 1000 rivers are still rated very poor for cleanliness. But the Commissioner for the Environment reports that each one is getting cleaner.

  1. Compared with the OECD average of 11%, what percentage of available fresh water does New Zealand use?

Answer:  We use only 1.2% of our available fresh water. That’s nearly the lowest in the OECD.  

  1. How many Kilometres of rivers and streams have farmers so far fenced off?

Answer: Farmers have so far fenced off 45,000 km of rivers and streams (note: the 20,000 km being quoted by National is Fonterra farmers only), as well as doing a great deal of planting alongside waterways.

  1. What percentage of New Zealand dairy-farm rivers have farmers so far fenced off?

Answer:  Farmers have so far fenced off 90% of New Zealand rivers that run through farmland.

  1. What has made farmers fence off so many rivers at their own expense?

Answer: As farm income has risen, farmers have been able to afford to help clean up our rivers, and are doing more fencing and planting all the time.

  1. Where are New Zealand’s worst affected stretches of rivers:

Answer:  Our worst-affected stretches of river are downstream from urban, not rural, areas.

  1. What is the WRC’s solution to improving river water quality?

Answer:  Cap farming at its current level.

  1. What will be the result of stopping farm intensification?

Answer:  The loss of precious new export income that would allow us to afford better hospitals, better schools – and a cleaner environment.

There are river care and land care groups on all main and many small rivers across New Zealand. They’re spending millions of dollars to improve water quality.

These groups include farmers, Fonterra, Dairy NZ, NZ Beef and Lamb, Landcare NZ, Federated Farmers, iwi, fertilizer companies, universities, and regional councils.

The fact is, thousands of New Zealand farmers are heavily committed financially and ethically to making our rivers cleaner. 

THE DOWNSIDE OF A HUGE UPSIDE

So why do we have this problem with our rivers? It goes back to the early days of our farming and industry. The upside of those pioneering efforts was that farmers gave New Zealanders the highest standard of living in the world. The downside was that, with no practical alternatives, they had to use the rivers as a means of disposal. Everyone accepted that. There was little or no dissent.

Then in the 1960s, attitudes changed. And work began on cleaning up.

FARMERS MADE US A RICH COUNTRY, NOT THE STATE.

We remind you who built the farming industry on which New Zealanders still depend for their high standard of living. It wasn’t the state. That’s why we say innovative, commonsense farmers have a better record of fixing environmental problems related to farming than heavy-handed bureaucrats.

MORE FACTS ABOUT HOW WE’RE IMPROVING OUR WATER QUALITY

There are three sources of pollution in waterways: pathogens (faeces), sediment (erosion) and nutrients (mainly phosphates and nitrogen).

Every year the pathogens and sediment problems have got better. And we’re now seeing a reduction in phosphates thanks to the efforts of farmers, the government, regional councils and other groups.

Something you should know when you hear the word nitrogen. Nitrogen occurs naturally in waterways – if it didn’t we’d have a much bigger problem.  Life in the water would die.

Rivers can handle quite heavy loads of nitrogen.  There’s no real problem until blooms appear. That’s a rare occurrence in New Zealand’s 1000 rivers.

NIWA’s Dr Davies-Colley had this to say about our improving water quality:

  • “The fact that some heavily polluted rivers have turned the corner in recent years gives us cause for optimism for the future.”

“A relatively few urban- and mine-affected rivers in New Zealand probably have the worst water quality because of mobilization of toxic contaminants such as heavy metals as well as severe habitat modification.”
