Coastal lagoons are fragile ecosystems that account for 13-15
percent of the world's littoral zone. Coastal lagoons constitute an
essential environmental reservoir for fluvial sediments due to
their capacity to retain them and also the accompanied elemental
pollutants. In recent times it has been a common practice to
redistribute large amount of coastal sediments for beach
nourishment projects to combat shoreline retreat. The problem of
beach/shoreline recession/erosion are as a result escalating
impacts of emerging global geophysical changes, such as rising sea
levels, and coastal development. This book examines the
environmental effects of engineered solutions of massive
dredge-and-fill methods which have been adopted world-wide in
regard to the issue of shoreline erosion.
The Ghana's rocky shore is unique along the Gulf of Guinea from
Cote d'Ivoire to western Cameroon (West Africa). This suggests the
existence of specific biotopes of species assemblages on spatial
scales. The variability of environmental factors has been
highlighted as the main causes of variations in the rocky
intertidal communities. This book presents species assemblage
patterns on spatial scales, test statistical differences in taxa
assemblages and model taxon-environment interactions.
