Biomass estimation was carried out for three even-aged dominant mangrove species (Avicennia alba, Excoecaria agallocha and Sonneratia apetala) in two regions of Indian Sundarbans with two distinct salinity regimes for three consecutive years (2008-2010) and the results were expressed in tons per hectare (tha-1). In the western region, the total mean biomass of the mangrove species varied as per the order A. alba (41.65tha-1 in 2008, 55.79tha-1 in 2009, 60.86tha-1 in 2010)&gt;S. apetala (31.76tha-1 in 2008, 32.81tha-1 in 2009, 39.10tha-1 in 2010)&gt;E. agallocha (13.89tha-1 in 2008, 15.54tha-1 in 2009, 18.28tha-1 in 2010). In the central region, the order was A. alba (42.06tha-1 in 2008, 57.09tha-1 in 2009, 64.57tha-1 in 2010)&gt;E. agallocha (15.30tha-1 in 2008, 20.02tha-1 in 2009, 24.24tha-1 in 2010)&gt;S. apetala (6.77tha-1 in 2008, 9.46tha-1 in 2009, 11.42tha-1 in 2010). Significant negative correlation was observed between biomass of S. apetala and salinity (p&lt;0.01), whereas in case of A. alba and E. agallocha positive correlations were observed (p&lt;0.01). Species-wise linear allometric regression equations for biomass prediction were developed for each salinity zone as a function of diameter at breast height (DBH) based on high coefficient of determination (R2 value). The allometric models are species-specific, but not site-specific. © 2013 Elsevier Ltd.

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 be havior 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. © Springer International Publishing AG, part of Springer Nature 2019.

Estuarine Pollution in the Lower Gangetic Delta: Threats and Management

Estuarine pollution in the lower Gangetic delta: Threats and management

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." © Springer India 2015.
