Transforming Taranaki

Transforming Taranaki, a booklet published in November 2011, tells how farmers, with the encouragement of the Council and the dairy industry itself, are becoming better guardians of the environment by working to reduce the amount of diffuse-source pollution going into the region’s rivers and streams – the material that is washing off pastures and into waterways.
