Challenges of achieving good environmental status in the Black Sea

The Black Sea has suffered severe environmental degradation. Governance of the Black Sea region is complex and results in a series of scale mismatches which constrain management to deliver Good Environment Status as required by the EU Marine Strategy Framework Directive. This paper develops a simple classification of spatial scale mismatches incorporating the driver, pressure, state, welfare, response framework. The scale mismatch classification is applied to two major environmental problems of the Black Sea, eutrophication and small pelagic fisheries. A number of scale mismatches are described and classified and potential solutions are identified.
