Management tools for the Water Framework Directive




Management of nutrients draining in the farmland has similarities with management of biodiversity; this principally encompasses leaving natural and semi-natural vegetation in buffer zones along boarders of streams.





Landsat data were used to map the farmland including crops, meadows, shrubs, forest and set-aside areas. Buffers around streams showed favorable/unfavorable places for nutrients capture and areas which was favorable for preservation of biodiversity in the farmland.  


As a part of the project Management of Biodiversity in the Latvian Farmland - a decision support system”, we demonstrated relative simple and cost effective decision support systems for management of nutrient leaching and biodiversity in the Latvian farmland. Developed biodiversity filters were used on farmland and showed a clear connection between biodiversity and nutrient management. The system easily monitors buffer areas along streams which have importance for capturing nutrients and preserving biodiversity.  The approach was developed locally and tested on a national scale to meet the requirements of EU Water Framework Directive and  Integrated Water Resources Management (IWRM) new EU CAP.
