Book Description
This book offers a comprehensive and accessible guide covering various aspects of trace metal contamination in abiotic and biotic matrices of an iconic Indian tropical mangrove wetland – Sundarban. Divided into nine chapters, the book begins by discussing the fundamental concepts of sources, accumulation rate and significance of trace metal speciation, along with the impact of multiple stressors on trace metal accumulation, taking into account both tourist activities and the exacerbating role of climate change. The second chapter presents a detailed account of the sampling strategy and preservation of research samples, followed by exhaustive information on sediment quality assessment and ecological risk, instrumental techniques in environmental chemical analyses, quality assurance and quality control, along with the Sediment Quality Guidelines (SQGs). Using raw data, the sediment quality assessment indices (e.g., pollution load index, index of geoaccumulation, Nemerow Pollution Load Index etc.) and conventional statistical analyses are worked out and interpreted precisely, allowing students to readily evaluate and interpret them. This is followed by chapters devoted to trace metal accumulation in sediments and benthic organisms, as well as acid-leachable and geochemical fractionation of trace metals in sediments. The book then focuses on chemical speciation of butylin and arsenic in sediments as well as macrozoobenthos (polychaetous annelids). Finally, potential positive role of the dominant mangrove Avicennia in sequestering trace metals from rhizosediments of Sundarban Wetland is elaborately discussed. This timely reference book provides a versatile and in-depth account for understanding the emerging problems of trace metal contamination – issues that are relevant for many countries around the globe.

Book Description
Wetlands Conservation An up-to-date overview of approaches for addressing wetlands degradation and its effects on ecosystem services, human health, and other ecosystems Wetlands are essential sources of biodiversity, water purification, groundwater replenishment, flood control, storm protection, sediment retention, recreation and tourism, and more. Human exploitation of natural resources over the past 200 years has caused significant wetlands degradation and loss. Although the Ramsar Convention of 1971 drafted polices for wetland conservation and responsible use, many wetland sites remain inadequately conserved or managed. Maintaining the ecological balance and equilibrium of wetlands requires a clear understanding of the vital role of wetlands, the difficulties they face, and the policies enacted for their protection. Wetlands Conservation: Current Challenges and Future Strategies summarizes both current and emerging management strategies, trends, and policies regarding wetlands protection around the world. The authors provide accurate scientific information on wetlands while discussing the effects of climate change, global warming, modernization in agriculture, and other key topics. Designed to assist in the development of future solutions for wetlands conservation and management strategies, this important volume: Highlights the environmental, socioeconomic, and cultural importance of wetlands Identifies the factors responsible for the failure of many conservation initiatives Describes the natural and anthropogenic factors of wetlands degradation Discusses the role of community-based wetlands conservation and management Explores Ramsar wetlands conservation and its impacts worldwide Wetlands Conservation: Current Challenges and Future Strategies is an invaluable resource for graduate and postgraduate students, researchers, ecologists, policymakers, conservation organizations, and others working in the field of natural resources management.

Book Description
Human beings have a long historical relationship with the coast. Initially it provided food and security, later forming important locations for industrial and commercial development. Now the emphasis has shifted towards leisure and conservation, although the former functions remain crucial. However, it is only very recently that people have started viewing the coast as a common and valuable resource that requires rational utilisation and scientific management in order to sustain its attractiveness. Of course, enlightened management comes only through understanding of the complicated coastal regions, which enables coastal managers to balance pressures from different sectors and to minimize risks. Scientific knowledge will continue to be the most important basis for resolving the conflicts between coastal users and interest groups such as developers and ecologists. Coastal management has also shifted from traditional restorative or remedial actions towards planned avoidance of other conflicts. Despite rapid advancement in coastal sciences over recent decades, most of the major coastal issues have remained outstanding in the agenda. Control of shoreline erosion and protecting sea level rise continue to be crucial problems facing coastal scientists. Destructive coastal storms still cause tremendous damage, particularly in low altitudes. Wetland and estuary reclamation have led to the loss of the most valuable estuary wetlands which are required to sustain biological productivity and biodiversity. This volume includes papers on marine and coastal pollution, eutrophication, aquaculture, conservation and utilization, coastal wetlands, and coastal zone management.

Book Description
Explores how the management of wetlands can influence carbon storage and fluxes. Wetlands are vital natural assets, including their ability to take-up atmospheric carbon and restrict subsequent carbon loss to facilitate long-term storage. They can be deliberately managed to provide a natural solution to mitigate climate change, as well as to help offset direct losses of wetlands from various land-use changes and natural drivers. Wetland Carbon and Environmental Management presents a collection of wetland research studies from around the world to demonstrate how environmental management can improve carbon sequestration while enhancing wetland health and function. Volume highlights include: Overview of carbon storage in the landscape Introduction to wetland management practices Comparisons of natural, managed, and converted wetlands Impact of wetland management on carbon storage or loss Techniques for scientific assessment of wetland carbon processes Case studies covering tropical, coastal, inland, and northern wetlands Primer for carbon offset trading programs and how wetlands might contribute The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity.Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

Book Description
This document aims to provide an understanding of the scientific methodology that can be employed to demonstrate, monitor and assess mangrove-relevant environmental services by using case studies of mangroves in Hai Phong City and the Can Gio district of Ho Chi Minh City in Vietnam. In addition to previous work, this methodology evaluates the water purification services of mangroves in the context of existing policies on payment for forest environmental services in Vietnam, and discusses lessons learned, and funding requirements for effective assessment, evaluation and monitoring of the service. The findings contribute to identifying users and buyers of mangrove environmental services and developing implementation and monitoring mechanisms for payment for forest environmental services (PFES) through the application of environmental indices. The document is made in the hope that future studies can apply its methodology in other regions of the country to develop a database for evaluating the roles of mangroves throughout Vietnam.
