Priority
Irrigation; technology and irrigation management, improved cropping practices
Water reuse;linking technologies and legal framework,(full water pricing) determination of required water quality for different agriculturalpurposes, fostering the reuse of urban effluents in water scarce regions.

Priority
Nutrients and pesticide management; measures to reduce inputs and to address leakage and run-offthrough hydromorphology or agricultural practices, while tapping the potential of nutrients resource from urban water schemes such as biosolids

The potential of ditch dams and lime cassettes
Potentially 80-100% reduction of dissolved Phosphorus (mainlyPhosphates), which is the main part of the bio-available fraction.
10-30 % reduction of particulate Phosphorus
The sediment of the dam can be removed and re-used
The used filter material can potentially be spread on the fields.
Requires no additional land area.
Applicable for a large part of the arable land in the Baltic Sea States.
Simple and cheap mitigative action
