This book examines the impacts that the COVID-19 lockdown has had on environmental and ecological health, with a focus on coastal ecosystems in the Lower Gangetic Delta. The book begins with an overview of COVID-19's spread and impact before and after the lockdown in the focus region, then addresses the specific impacts that the lockdown period had and continues to have on air quality, marine and estuarine water quality, coastal biodiversity, and the livelihoods of the region's inhabitants, especially those who live below the poverty line. The decrease in human activity combined with the complete closure of various sectors, including air travel, oil and gas drilling, and construction, has had a pronounced effect on biodiversity and overall environmental health that is yet to be fully realized. The book sheds light on these changes and assesses how biodiversity, ambient air quality, and ecosystem functioning will progress as COVID-19 remains a threat and the lockdown persists. The studywill be of interest to researchers, government officials and professionals dealing with disaster management, environmental science, biological science, and health.

True mangrove flora and their associates in the lower Gangetic region are noted for their wide spectrum of ecosystem services in which carbon storage and sequestration by the forest is one of the most important components. Many researchers are updating the carbon repository of the lower Gangetic delta mangroves with the aim to ascertain their role to reduce the carbon dioxide level of the near surface atmosphere. However, due to difficulty in assessment, marketing, and lack of clarity over ownership of natural resources, the mangrove-based carbon trading system has not yet crystallized.There is an estimated 13.76 Mha of mangrove forests world-wide, approximately 20% (2.6 Mha) of which is potentially investible for carbon finance projects, based on the probability of imminent threat. The magnitude and the variability of threats to which the mangroves of the lower Gangetic delta are exposed to have made the trading process more complicated. In addition, gaps also exist between the national government policy and the trading of the blue carbon projects, which has kept the future of such projects remain on hold. The authors put forward the views that the creation of more financial facilities for restoration and expansion of blue carbon (preferably mangroves) with the involvement of the local communities can provide the initial capital involved in developing mangrove-based carbon projects. This includes the costs of conducting feasibility studies, implementing capacity-building programs, monitoring the health of the mangrove plantation/restoration on regular basis, and creating mangrove-based alternative livelihood programs that will support island dwellers of the region in order to accelerate the magnitude of mangrove-based carbon projects leading to growth of the mangrove trading market.

This book critically analyzes the water quality in the lower Gangetic delta, and examines the environmental conditions and physical processes operating in this rich ecosystem. Readers with an interest in environmental science, geography, oceanography, marine biology, environmental biology, aquatic pollution and ecology will find the research presented here most appealing. Readers will discover critical aspects of the chemistry of the estuarine water (particularly that of Hooghly and Matla estuaries) in the lower stretch of the delta region along with the causes and effects of pollution in and around this region. Particular attention is given to the bioaccumulation of conservative pollutants in edible fishes and floral communities thriving in this region. Several case studies are also incorporated to highlight the vulnerability of pollution in this region. Chapters also address the impacts of climate change (specifically acidification) on the concentration and behavior of conservative pollutants. Finally, the book highlights some mitigation measures at the technology and policy level to minimize the negative impacts posed by different groups of pollutants on the estuarine biodiversity.

Mangroves are basically salt tolerant forest ecosystems found mainly in tropical and sub-tropical inter-tidal regions. Till about 1960s, mangroves were largely viewed as “economically unproductive areas” and were therefore destroyed for reclaiming land for various economic and commercial activities. Gradually, with the passage of time, the economic and ecological benefits of mangroves have become visible and their importance is now well appreciated. Today, mangroves are observed in about 30 countries in tropical subtropical regions covering an area of about 99,300 Sq.Km. However, during the past 50 years, over 50% of the mangrove cover has been lost, mainly because of the increased pressure of human activities like shrimp farming and agriculture, forestry, salt extraction, urban development, tourist development and infrastructure. Also, dam on rivers, contamination of sea waters caused by heavy metals, oil spills, pesticides and other products etc. have been found to be responsible for the decline of mangroves. Although the temperature effect on growth and species diversity is not known, sea-level rise may pose a serious threat to these ecosystems The present book addresses all these important issues in separate chapters with some interesting case studies whose data may serve as pathfinder for future researches in the sphere of the influence of climate change on mangrove ecosystem. The role of mangroves in the sector of bioremediation is a unique feather in the crown of this coastal and brackishwater vegetation that may be taken up by the coastal industries in order to maintain the health of ambient environment. This book seeks to discover and to assess the vulnerability of climate change on mangrove flora and fauna, their role in carbon sequestration and some interesting case studies by some groups of dedicated researchers that may serve as the basis of future climate related policies.

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.

The book presents recent research on marine ecology in different parts of the world. It aims to shed light on relevant topics for budding marine ecologists.The “blue soup” of Planet Earth, which comprises both biotic and abiotic components, is essential to keeping the wheel of civilization running. Four major ecosystem service categories have been identified within this context, namely provisioning services such as water, food, mangrove timber, honey, fish, wax, fuel wood, fodder and bioactive compounds from marine and estuarine flora and fauna; regulating services such as the regulation of climate, coastal erosion, coral bleaching and pollution; cultural services encompassing recreational (tourism), spiritual and other non-material benefits; and supporting services such as nutrient cycling and photosynthesis. These valuable services are obtained from various resources that must be conserved for the sake of humanity. This book presents data for each resource type, not just in the form of a simple description, but also through case studies that resulted from several research projects and pilot programs carried out in different parts of the world. Statistical tools were also used to critically analyze the influence of relevant hydrological parameters on the biotic community. Advanced research in marine and estuarine ecology is based on the use of sophisticated instruments, sampling precision, statistical tools, etc., which have also been highlighted in the book.
