Clean Water- Productive Land

We hypothesized that the majority of contaminants (nutrients, sediment and faecal microbes), come from the minority of the land (e.g. 80:20 rule), termed critical source areas (CSAs) – irrespective of scale. Focusing mitigation strategies on CSAs improves their cost-effectiveness. Being able to determine and manage CSAs with models and tools (at a range of scales) will inform policy and industry guidelines that will significantly improve New Zealand's rural industries, Māori, and local and central government ability to achieve good water quality outcomes. A team of Scientists from AgResearch, ESR, NIWA and Landcare are together working to determine the sources of the majority of contaminates and develop ways to manage and mitigate them.
