More than 70% of the beaches in the World are in decreasing stage during the past few decades, and the Black sea
beaches are not exclusion. The paper gives a brief conceptual review of published and unpublished results of author’s longterm
complicated study (1995-2010) in different areas of the Crimean coastline. Interconnections between marine
communities and beach erosion are analyzed as well as some anthropogenic impacts on processes in beach area. Selfaccelerating
mechanism of beach erosion and marine communities degradation was suggested. Two interrelated components
in the system “beach-sea” are crucial in regulating the balance of sand on the beach in our case - the coastal vegetation and
benthic communities producing clamshells. Two stable state of coastline - fluctuating stable sand beach and no sand beach
state - can be. It should be noted that with the rise of sea level, is now observed, the steady state beach is only possible if the
existing balance of sand is positive. New perspectives for rational management of sandy beaches require paradigm shifts.
Sustainable long-term management of our beaches requires a set of alternative strategies for environmental management and
the timely switch from one strategy to the alternative one.
