Dairy NZ: time for celebration?

The dairy industry is celebrating the environmental achievements of farmers excluding stock from waterways. According to Dairy NZ's three year progress report on it's Water Accords the vast majority of farmers have now fenced farms out of significant waterways and virtually all stock crossings have bridges and culverts in place. But scientists point out that keeping cows out of rivers will do little to combat issues around contamination of aquifers and rivers from pollutants seeping through soils.
