14.4.2 Eutrophication Abatement Strategy
The development of eutrophication abatement strategy aimed at prevention of aquatic
ecosystems degradation should be based primarily on identifying all sources of
nutrients discharge to surface waters and their share in the total external load. This
approach will give the opportunity to identify the key goals of particular attention
and manage the financial streams in a rational way to achieve the real reduction of
total nutrient load. Currently, significant reduction of nutrient loads discharged into
