This Brief deals with the reconstruction of Holocene paleoenvironment in the central part of Bangladesh in relation to relative sea-level (RSL) changes which is 200 km north from the present coastline. Lithofacies characteristics, mangal peat, diatom and paleophysiographical evidences were considered to reconstruct the past position and C-14 ages were used to determine the time of formation of the relative sea-level during the Holocene. With standard reference datum the required m.s.l. at the surface of five sections are calculate and the RSL curve suggests that Bangladesh has experienced two mid Holocene RSL transgressions punctuated by regressions. The abundant marine diatom and mangrove pollens indicates that the highest RSL transgression in Bangladesh is around 6000 cal BP which is attained at least 4.5 to 5m higher than the modern m.s.l. After this phase, the relative sea-level started to fall and consequently a freshwater peat developed around 5980―5700 cal BP. The abundant mangrove pollens in salt-marsh succession shows the regression around 5500 cal BP and, the height was 1―2 m higher than the modern sea level. These and more interesting findings are discussed in this Brief.

The Intergovernmental Panel on Climate Change (IPCC) is the leading international body for assessing the science related to climate change. It provides policymakers with regular assessments of the scientific basis of human-induced climate change, its impacts and future risks, and options for adaptation and mitigation. This IPCC Special Report on the Ocean and Cryosphere in a Changing Climate is the most comprehensive and up-to-date assessment of the observed and projected changes to the ocean and cryosphere and their associated impacts and risks, with a focus on resilience, risk management response options, and adaptation measures, considering both their potential and limitations. It brings together knowledge on physical and biogeochemical changes, the interplay with ecosystem changes, and the implications for human communities. It serves policymakers, decision makers, stakeholders, and all interested parties with unbiased, up-to-date, policy-relevant information. This title is also available as Open Access on Cambridge Core.

To date, a vast amount of the world’s oceans remains uncharted. With water covering more than 70 percent of the Earth’s surface, maritime and oceanographic exploration and research is vital. Oceanography and Coastal Informatics: Breakthroughs in Research and Practice is a critical source of academic knowledge centered on technologies, methodologies, and practices related to the biological and physical aspects of the ocean and coastal environments. This publication is divided into four sections: climate change and environmental concerns; data analysis and management; fisheries management and ecology; and GIS, geospatial analysis, and localization. This publication is an ideal reference source for oceanographers, marine and maritime professionals, researchers, and scholars interested in current research on various aspects of oceanography and coastal informatics.

The edited book deals with climate change and its response to river system which is one of the most burning issues of the Global environment. Due to urbanization and industrialization land degradation and resource depletion are happening and promoting livelihood challenges in the world which is reflected in the book too. The book addresses the construction of dams over large rivers and its possible consequences in the environment. Changes of the hydrology and sedimentology are to be addressed in the book. The climate change phenomena and associated geomorphic hazards and contemporary environmental issues such as sea level rise, coastal flood, drought, wind erosion, flood, soil erosion, landslide, depletion of ground water, coastal erosion etc. are elaborated in the book with suitable methods and techniques. So this edited book will contribute a lot to general to particular filed of studies and will help to geographers, geomorphologists, environmentalists, planners, policy makers and developers for studies and promoting regional plans and development.

This book explores the Sundarbans eco-region from a trans-boundary perspective, examining the cross-country interaction that helps planners to develop more efficient coastal zone planning for the delta. The dynamic ecosystem of the Sundarbans is considered the largest coastal delta in the world. It is located in the Bay of Bengal and spans across Bangladesh and West Bengal (India). Featuring chapters by experts from a range of fields, it addresses (i) risk factor analyses, and the geohydrological, climatic, natural, socio-economic, and anthropological factors related to the Sundarbans; (ii) strategies for sustainability in natural resource management in trans-boundary Sundarbans, cutting across political boundaries; (iii) improved agriculture, fisheries, and forestry practices and their impacts on the socio-economy for livelihood security; and (iv) a future road map for improvements. This book will be of value to those working in academia, as well as to experts and professionals in coastal zone planning and management.

Mangroves are one of the most productive and biologically important blue-carbon ecosystems across the coastal intertidal zone of earth. In the current scenario of serious environmental changes like global warming, climate change, extreme natural disasters, mangrove forests play a vital role in mitigating greenhouse gas emissions and maintaining ecosystem balance. Mangroves are unique ecosystems with rich biological diversity of different taxonomic groups exhibiting great ecological and commercial importance. The book consolidates existing and emerging information on ecology of mangroves, with a special reference to their biodiversity and management. It emphasizes on the role of mangroves in providing various ecological services. The book is a comprehensive compilation covering all aspects of mangrove ecology. It is useful for students and researchers in ecology, plants sciences and environmental sciences.

The seabed in southern Scandinavia contains numerous traces of a submerged landscape that is thought to be the remnant of a once important habitat for Mesolithic hunter-gatherers. Large parts of this landscape were gradually flooded by rising seas between 9500 and 4000 BC and perceptions of the Maglemose culture (9500-6400 BC) have, consequently, been based almost exclusively on former inland settlements. As a result, Early and Late Mesolithic societies have been understood as almost diametrically opposed with regards to their reliance upon marine resources and their degree of sedentism. The main objective of the book is to investigate two questions that are directly related to our current understanding of the populations of the now submerged areas: 1) Do we have a representative picture of the spread of Early Mesolithic sites in southern Scandinavia, or does the weighting towards inland sites reflect the fact that coastal sites have not been identified below present-day sea-level? 2) How did sea-level changes impact Mesolithic populations at different temporal and spatial scales, and how were these experienced from 8000-4000 BC? The book presents an extensive and up-to-date review of various types of evidence from the Boreal period such as faunal remains, fishing instruments, d13C values in bones, settlement positions and available marine resources. These are used to discuss the extent to which marine resources were utilised in the Maglemose culture. Another central component of this book is a series of new coastline models made to determine the Mesolithic sea-level changes / coastline positions. The eight new coastline models are created to facilitate new evaluations of possible relationships between sea-level changes and cultural changes. On the basis of the new coastline models the book also presents the preliminary results of 47 diver investigations conducted with the aim of identifying potential coastal settlements from the Maglemose culture.
