The ever increasing emission of carbon dioxide due to rapid industrialization, urbanization, unplanned tourism and alteration of land use pattern is causing unprecedented changes to marine biodiversity. Irrespective of political philosophy, nation, caste, sex and religion, mankind is under the appalling shadow of climate change. Today nature-based approaches for the mitigation of climate change are increasingly accepted as part of the low-cost solution. Thrust has been given by several scientific communities to assess the magnitude and viability of carbon sequestering potential of plants. Coastal producer communities like mangroves, salt marsh grass, seagrass beds, and seaweeds absorb atmospheric carbon dioxide during the process of photosynthesis. This carbon known as the ‘blue carbon’ is thus associated with the marine and estuarine ecosystems. However, a number of gaps in our scientific knowledge on blue carbon domain still exist. Molluscs, coral reefs, phytoplankton, which are amongst the important storehouses of carbon, have not been addressed. Very few scientific studies on the carbon stored in these valuable natural vaults have been performed, and no data bank is available on their carbon sequestering capacity on global basis. The methodologies for assessing blue carbon stock also need further standardization so that credit from blue carbon reservoir is accepted by the International bodies in the form of a concrete policy. It is a matter of great appreciation that Conservation International (CI), the International Union for Conservation of Natural Resources (IUCN), and the Intergovernmental Oceanic Commission (IOC) of UNESCO is collaborating with governments, research institutions, non-governmental and international organizations, and communities around the world to develop management approaches, financial incentives and policy mechanisms for ensuring conservation and restoration of blue carbon ecosystems and implement projects around the world that demonstrate the feasibility of blue carbon accounting, management, and incentive agreements. The present book has critically presented the data bank for each community of blue carbon not merely in the form of text description, but also through case studies that are the outcomes of research projects and pilot programmes.

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 provides a cross-sectoral, multidisciplinary assessment of the major verticals of Blue Economy relevant to the mangrove ecosystem in Indian Sundarbans, which is a deltaic complex at the apex of Bay of Bengal. This book evaluates the feasibility of Blue Economy considering the natural resource base in this mangrove dominated deltaic complex. Chapter 1 discusses the need of expanding different marine and estuarine oriented verticals of Blue Economy as the land resources are gradually becoming depleted. Chapter 2 highlights the wide spectrum of biotic and abiotic resources of the Indian Sundarbans which can serve as the strong foundation of expanding Blue Economy in the region. Chapter 3 highlights several mangrove based livelihoods that are not only innovative, but may present new opportunities to initiate cottage industries. Chapter 4 highlights the threats associated with Blue Economy in Indian Sundarbans like, sea level rise, acidification of water, weather extremes, pollution, over-exploitation of natural resources, etc., along with ground-zero environmental data collated over three decades. Chapter 5 offers several solutions to combat the threats to regional Blue Economy emphasizing both technology and policy based management. The book attempts to align the proliferation of different sectors of Blue Economy in the framework of Indian Sundarbans.

Sustainable management of natural resources is an urgent need, given the changing climatic conditions of Earth systems. The ability to monitor natural resources precisely and accurately is increasingly important. New and advanced remote sensing tools and techniques are continually being developed to monitor and manage natural resources in an effective way. Remote sensing technology uses electromagnetic sensors to record, measure and monitor even small variations in natural resources. The addition of new remote sensing datasets, processing techniques and software makes remote sensing an exact and cost-effective tool and technology for natural resource monitoring and management. Advances in Remote Sensing for Natural Resources Monitoring provides a detailed overview of the potential applications of advanced satellite data in natural resource monitoring. The book determines how environmental and - ecological knowledge and satellite-based information can be effectively combined to address a wide array of current natural resource management needs. Each chapter covers different aspects of remote sensing approach to monitor the natural resources effectively, to provide a platform for decision and policy. This important work: Provides comprehensive coverage of advances and applications of remote sensing in natural resources monitoring Includes new and emerging approaches for resource monitoring with case studies Covers different aspects of forest, water, soil- land resources, and agriculture Provides exemplary illustration of themes such as glaciers, surface runoff, ground water potential and soil moisture content with temporal analysis Covers blue carbon, seawater intrusion, playa wetlands, and wetland inundation with case studies Showcases disaster studies s

A global blue economy is an economic arena that depends on the benefits and values realized from the coastal and marine environments. This book explains the "sustainable blue economy" as a marine-based economy that provides social and economic benefits for current and future generations. It restores, protects, and maintains the diversity, productivity, and resilience of marine ecosystems, and is based on clean technologies, renewable energy, and circular material flows.

The extensive safety restrictions imposed globally due to the COVID-19 pandemic have brought significant changes to almost all environmental parameters. The largest pandemic of the century has left an indelible mark on all aspects of human life and the environment. This book revolves around COVID-19 and its influence on all biotic and abiotic components on earth, with a focus on the regulatory role of air quality during the pandemic, environmental toxicity and susceptibility to COVID-19, and the impact of the lockdown on different ecosystems. The book fundamentally explains the biology of SARS-CoV-2 and the pathophysiology and epidemiology of COVID-19. Dedicated chapters highlight the ongoing global cutting-edge research on COVID-19, control and safety measures, and public health concerns. COVID-19 and Emerging Environmental Trends: A Way Forward is aimed at graduate and postgraduate students as well as researchers in environmental and medical science, health and safety, and ecology. This book offers a multiperspective and multidisciplinary approach to the discussion of the pandemic as well as emerging environmental issues, current trends, and a way forward. As humanity stands face-to-face with the largest global crisis in recent times, this book helps readers to easily understand its various aspects from a beginner’s perspective, without going into the intricate technicalities of medical science or environmental science, and beautifully juxtaposes critical issues with lucid language and flexible scientific explanations.
