Collaborative working to develop a new water quality model

We have been helping to assess the effectiveness of the long term DEFRA programme of encouraging uptake by farmers of catchment sensitive farming (CSF) measures to reduce diffuse pollution including nutrients, which pose a local, national and global threat to ecosystems, something we would like to highlight on World Environment Day.

We developed a new water quality model in collaboration with the Environment Agency and SMHI, Sweden to evaluate the effectiveness, bringing together diffuse and point source . The results are promising and show the CSF approach has been effective (there has been 34% uptake on agricultural land) where they have been implemented.

Barry Hankin, Head of Environmental Modelling, presented on the new HYPE model at the International conference on Land Use and Water Quality in Denmark, showing how for the first time we have a national unsteady, process based water quality model which represents the event driven nature of pollution transport. At the conference we’ve seen how other countries are also adopting a CSF style approach, which means engaging with farmers, providing training, advice and help securing Environmental Stewardship funding.
