This book provides an important insight that increases the scope of knowledge and invigorates readership in areas of lagoon dynamics and management. In attaining this zeal, both natural and anthropogenic dimension in determining associated impacts and conservation of these vital ecosystems partook in its paramount consideration. To further enrich the book's coverage, the authors' scientific excellence and overall acquired experience in their respective areas of specialisation and background was explored to encompass research from different geographic localities. The result of this approach brought about significant advantage due to the fact that opportunities arose where researched information from the tropic, Mediterranean and temperate based lagoon ecosystems were achieved, inertly, providing ecological examination at micro and macro organismic levels. Moreover, the book covers other specialised areas affecting directly or indirectly lagoon biogeochemistry and usage such as; species interaction, microbial threats, anthropogenic and edaphic pressures, application of biotechnology (eg: application of biomarkers), aquaculture, marine and inland conservation methodologies and waste management. Thusly, the book forms a crucial basis of improving existing knowledge on the management of lagoons and related habitat response to ecological impact. Concurrently, the book also provides a fundamental preview of how human aspiration of enhancing entertainment amenities, a craving for resources, and generation of waste and ultimate degradation of the lagoon ecosystem is and should be a global concern. Conspicuously indicated in the book are some of the lagoons ecosystems already being threatened or degraded. Therefore, the chapters have successfully provided the required width and breadth in disseminating vital information relating lagoon ecology and management.
