Tropical deltas of the world are in decline and are threatened by climate change, geo-environmental dynamics, natural hazards, and disasters. This book is a comprehensive discussion of the present delta crisis and the various risks the deltas are facing due to human and natural factors. It addresses their resilience, the importance of biodiversity, and the future adaptations for sustainable management of tropical deltas. The use of geospatial tools for the assessment and modeling of environmental degradations and the applications of artificial intelligence (AI) and machine learning (ML) are examined in 22 chapters, from different major deltas of the world, to help readers understand the interdisciplinary perspective of deltas’ vulnerability and sustainability. FeaturesProvides comprehensive coverage of global tropical deltas, their physical environments, hazard profiles, and socio-economic threats in a changing climate.Includes research-based discussions blended with global case studies to demonstrate the status of deltas around the world and the status of field-based investigations.Offers a holistic understanding of multifaceted dimensions of delta crises due to changes in landscape ecology, and the impact of various natural and man-made hazards.Addresses the critical challenges of sustainable management using a modeling approach with spatial maps and geostatistical diagrams.Discusses perspectives of restoring delta systems around the globe for solving environmental and societal problems.This reference book is for researchers, academics, graduate and senior undergraduate students in geography, geomorphology, hydrology, regional planning, environmental science, ecology, and engineering, and those interested in water conservation and sustainability, including professionals in industry and government, and human rights activists.

This Brief analyses and discusses the laterites in the Bengal Basin. The book highlights: (1) the definition, identification and classification of ferruginous materials, (2) the mode of laterite formation and its other horizons, (3) processes and theories of lateritisation, (4) determination of laterite ages, (5) recognition of palaeogeomorphic and palaeoclimatic significance and (6) geo-chronology and reconstruction of former lateritized landscapes. The chapters cover the tectono-climatic evolution of north-south laterite profiles of the north-western Bengal Basin on the Rajmahal Basalt Traps, Archean Granite-Gneiss, Gondwana Sandstones, Palaeogene Gravels and Older Palaeo-Deltaic Alluvium. The book uses advanced field-based studies, quantitative analysis and thematic mapping to cover various areas of palaeogeography and regolith geology of the Bengal Basin in connection with laterite genesis, palaeoweathering, tectonic geomorphology, Quaternary geomorphology and pedogeomorphology.It introduces laterites as a potential stratigraphic marker in Indian geology by explaining their palaeogeomorphic and palaeoclimatic significance.This Brief is a comprehensive resource to researchers, students and academicians of geography, geomorphology and geology working on laterites.

This book discusses the issue of riverbank erosion and its associated causes, risks and social challenges in the Bengal Delta.
