This book presents a comprehensive and innovative understanding of the role of shallow coastal ecosystems in carbon cycling, particularly marine carbon sequestration. Incorporating a series of forward-looking chapters, the book combines thorough reviews of the global literature and regional assessments—mainly around the Indo-Pacific region and Japan—with global perspectives to provide a thorough assessment of carbon cycling in shallow coastal systems. It advocates the expansion of blue-carbon ecosystems (mangroves, seagrass meadows, and salt marshes) into macroalgal beds, tidal flats, coral reefs, and urbanized shallow waters, demonstrating the potential of these ecosystems as new carbon sinks. Moreover, it discusses not only topics that are currently the focus of blue-carbon studies, i.e., sedimentary carbon stock and accumulation rate, but also CO2 gas exchange between the atmosphere and shallow coastal ecosystems, carbon storage in the water column as refractory organic carbon, and off-site carbon storage. Including highly original contributions, this comprehensive work inspires research beyond the specific regions covered by the chapters. The suite of new concepts and approaches is refreshing and demonstrates that blue-carbon research is indeed a vibrant new field of research, providing deep insights into neglected aspects of carbon cycling in the marine environment. At the same time the book provides guidance for policy makers to deliver benefits to society, for example the inclusion of blue carbon as a carbon offset scheme or the Nationally Determined Contribution (NDC) in the Paris Agreement, and also for building resilience in coastal socio-ecosystems through better management. This book is intended for all those interested in the science and management of coastal ecosystems.

This work summarizes the science and management of a rapidly expanding topic in climate science, namely adaptation and mitigation. The term 'blue carbon' refers to the rates, pathways and volumes of greenhouse carbon sequestered in coastal estuarine and marine ecosystems such as salt marshes, mangroves and seagrass meadows. Blue carbon and its vital role in climate change mitigation are central to this book. Readers find summaries and analysis of both the basic scientific data and data from blue carbon field projects, and a practical guide on how to manage a successful blue carbon field project. There is a discussion on how to maximize the carbon sequestration and consideration of whether blue carbon projects make a difference. The work is not only of interest to scholars involved in climate science, but also those in the marine sciences, and those in ecosystem ecology, biogeochemistry; geochemistry; estuarine and marine plant ecology.

This report explores the potential for mitigating the impacts of climate change by improved management and protection of marine ecosystems and especially the vegetated coastal habitat, or blue carbon sinks. The objective of this report is to highlight the critical role of the oceans and ocean ecosystems in maintaining our climate and in assisting policy makers to mainstream an oceans agenda into national and international climate change initiatives. While emissions' reductions are currently at the centre of the climate change discussions, the critical role of the oceans and ocean ecosystems has been vastly overlooked.

This book outlines the performance and management of mangroves in the changing climatic scenario of the Asia-Pacific region and draws examples and lessons from the national and community-driven mangrove conservation programs of relevant countries including Pakistan, India, Bangladesh, Sri Lanka, Myanmar, Thailand, Cambodia, Indonesia, the Philippines, and Japan as well as the Pacific islands. By highlighting the major drawbacks that hinder effective mangrove conservation, the book contributes towards enhancing climate resilience of communities through proposition of corrective methods and ameliorative approaches of mangrove conservation. Mangroves play an important role in adapting to climate change and provide a plethora of ecosystem services that are fundamental to human survival. Yet these ecosystems are exceptionally prone to extinction due to increased human interventions and changes in environmental boundary conditions. Especially in the Asia-Pacific region, mangroves have dwindled at an exceptional high rate over the past three decades. As the threat of climate change hovers over millions of people in this region, particularly those who crowd the low-lying coastal areas, conservation/restoration of mangroves through appropriate policies and practices remain highly imperative. The primary target readers for this book are students and researchers in the fields of conservation and management of mangroves, especially from the developing tropical countries of the Asia-Pacific region. Other target groups comprise policy planners, practitioners, and NGO workers, who will be able to apply the collective knowledge from this work towards proactive mangrove conservation through effective mediation in local communities.

Despite their importance in sustaining livelihoods for many people living along some of the world’s most populous coastlines, tropical mangrove forests are disappearing at an alarming rate. Occupying a crucial place between land and sea, these tidal ecosystems provide a valuable ecological and economic resource as important nursery grounds and breeding sites for many organisms, and as a renewable source of wood and traditional foods and medicines. Perhaps most importantly, they are accumulation sites for sediment, contaminants, carbon and nutrients, and offer significant protection against coastal erosion. This book presents a functional overview of mangrove forest ecosystems; how they live and grow at the edge of tropical seas, how they play a critical role along most of the world’s tropical coasts, and how their future might look in a world affected by climate change. Such a process-oriented approach is necessary in order to further understand the role of these dynamic forests in ecosystem function, and as a first step towards developing adequate strategies for their conservation and sustainable use and management. The book will provide a valuable resource for researchers in mangrove ecology as well as reference for resource managers.
