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.
