J. Andrew G. Cooper - Böcker

The Last Beach is an urgent call to save the world's beaches while there is still time. The geologists Orrin H. Pilkey and J. Andrew G. Cooper sound the alarm in this frank assessment of our current relationship with beaches and their grim future if we do not change the way we understand and treat our irreplaceable shores. Combining case studies and anecdotes from around the world, they argue that many of the world's developed beaches, including some in Florida and in Spain, are virtually doomed and that we must act immediately to save imperiled beaches.After explaining beaches as dynamic ecosystems, Pilkey and Cooper assess the harm done by dense oceanfront development accompanied by the construction of massive seawalls to protect new buildings from a shoreline that encroaches as sea levels rise. They discuss the toll taken by sand mining, trash that washes up on beaches, and pollution, which has contaminated not only the water but also, surprisingly, the sand. Acknowledging the challenge of reconciling our actions with our love of beaches, the geologists offer suggestions for reversing course, insisting that given the space, beaches can take care of themselves and provide us with multiple benefits.

This book draws together a series of studies of spit geomorphology and temporal evolution from around the world. The volume offers some unique insights into how these landforms are examined scientifically and how we as humans impact them, offering a global perspective on spit genesis and evolution.Spits are unique natural environments whose evolution is linked to the adjacent coast and near shore morphology, sediment supply, coastal dynamics and sea-level change. Over the past century, Global Mean Sea Level (GMSL) has risen by 10 to 20 centimetres and many coastal spits represent the first sentinel against coastal submersion.Scientific research indicates that sea levels worldwide have been rising at a rate of 3.5 millimetres per year since the early 1990s, roughly twice the average speed of the preceding 80 years. This trend, linked to global warming will undoubtedly cause major changes in spit morphology.Spits are highly mobile coastal landforms that respond rapidly to environmental change. They therefore represent a signature of past environmental change and provide a landform indicator of climate change.

At the coast all is not what it seems.  Decades of beachfront development have seen a variety of efforts to stabilize the shoreline to protect ill-placed beachfront property, both from shoreline erosion and from storm damage. Both of these problems become increasingly critical in a time of rising sea level.  Many natural beaches are backed by sea walls, while others have been transformed by whole series of groynes, offshore breakwaters and a plethora of other schemes. Many recreational beaches are actually artificial replicas of the real thing, emplaced to protect badly placed infrastructure and maintained only through ongoing costly beach nourishment.  However, all of these attempts to stabilize the shoreline are far from benign. Degradation and even complete loss of the all important recreational beach sometimes results from seawall emplacement. Increasingly, the choice of shoreline stabilization approach will depend upon plans for future response to rising seas which in many cases may involve retreat from the shoreline rather than holding the line.  This book explores, through a series of case studies from around the globe, the pitfalls of shoreline stabilization and provides a ready reference for those with an interest in shoreline management.  It is particularly timely in a time of global change.
