Introduction to the case area
In the Waterdrive project the catchment area of Odense Fjord has been selected as a case area. The catchment area of Odense Fjord is a part of the main water catchment area of Odense Fjord and constitutes an area of 105.600 ha, of which the agricultural area constitutes approximately 63.960 ha.
”According to the River Basin Management Plan, nitrogen emissions to Odense Fjord must be reduced by a total of 549,3 tonnes N. Of this, a reduction of 345,8 tonnes N has to be reached by 2021. The remaining reduction requirement has been postponed to the third Water Plan period. The reduction requirements cor-respond a reduction of agricultural nitrogen emission by 38 % before 2021 and by a full 64 % in total. It is a very extensive reduction requirement with major consequences for agricultural production, if most of the effort is to take place on cultivated land. For this reason, it is relevant to examine the options of either completely or partially replacing restrictions on cultivated land with nitrogen measures on the edge of or outside of cultivated land.”
The Waterdrive project collaborates with landowners in two selected sub-catchments to Odense Fjord, as it is impossible to work with all landowners in this very large catchment area. Instead we have decided to fo-cus on a smaller area, which according to the program SCALGO should be potentially well suited for the establishment of drainage measures and wetlands. In Denmark, we have approximately 3000 sub-catch-ments called ID 15 each of them with an individual number. The areas are called ID 15 because they each represent approximately 1500 hectares and the main purpose is to use the retention in the specific area in the action plan.
