Roger Young: Cawthron Institute scientist on New Zealand's freshwater quality report

It's thought New Zealand's achievement of water quality targets hinges on every Kiwi getting behind efforts.  A new report has evaluated four contaminants —nitrogen, phosphorus, E. coli, and sediment— in rivers, lakes, and estuaries nationwide.  Every region needs a substantial reduction in at least one to meet freshwater standards.  75% of land is contributing more E. coli to water than is allowed.  Cawthron Institute scientist, Roger Young, told Tim Dower that achieving targets could require land-use changes in some areas and mitigation work in others.  He says in those cases, fencing and wetlands enhancements and protections could be enough.  LISTEN ABOVE See omnystudio.com/listener for privacy information.
