For the European Environment Agency this research provided a summary of approaches used to prevent / cure excessive nutrient enrichment of waters at an international / national / local level. The work assessed the effectiveness of these approaches and proposed a way forward for policy development.
Information was collected from 30 countries via the EEA Topic Centre. It included details of strategic goals set for nutrient reduction and a summary of measures to control inputs from sewage treatment plants, industry, agriculture, products and atmospheric sources plus approaches to protect sensitive areas / habitats and remediation techniques. The costs of implementation and their effectiveness were identified.
The research enabled the EEA and the participating 30 countries to assess best practise and cost / benefits of preventing / curing nutrient enrichment of waters.
