This work focuses on the potential impact of climate change on soil erosion in a monsoon-dominated sub-tropical region. Water-induced soil erosion due to extreme rainfall during the monsoon period is a major problem worldwide, from different environmental and socio-economic perspectives. This study region covered (South Bengal) is one of the fertile agricultural belts that produces a good amount of produce and contributes to the country's GDP. However, the rate of agricultural output has decreased rapidly in recent times due to a decline in soil fertility.The monsoon-dominated sub-tropical region has unique characteristics in terms of seasonal temperature fluctuations and the availability of rainfall events. The sub-tropical region is densely populated, with the majority of the population relying on rain-fed agricultural production systems. The declining rate of agricultural production has also established that soil fertility is declining and soil erosion is increasing. Numerous studies show that soil erosion is the major cause of the region's rapidly increasing trend of land degradation. A homeostatic mechanism cannot replace soil erosion, and a gap arises between soil erosion and regolith formation. Extreme changes in land use and land cover, population growth and the lacking support for traditional agricultural practices and management practices can accelerate the rate of soil erosion and its associated reservoir sedimentation in most countries of the tropical and sub-tropical environment. Quantitative information with maximum possible accuracy through validation regarding soil loss can be an essential part of the appropriate and sustainable soil and water conservation planning. The precise aspects of modern day management strategies are soil erosion susceptibility mapping using empirical and semi-empirical models in a GIS platform or the use of probability statistics.The main objective of this work is to propose the most suitable development strategies considering the amount of soil erosion for the present and future periods. Extensive field research has been done to identify the support practice factor that the local stakeholders adopt in this region.

Bidong Island is a small island located in the South China Sea, and is about 14 km from mainland Peninsular Malaysia. The island and the Bidong archipelago boast of its richness in diversity of both terrestrial and marine organisms and its undeniably pristine and thriving ecosystem. In 1975-1990, Bidong Island was formerly a UNHCR refugee camp for a quarter of a million Vietnamese "e;Boat people"e; escaping the Vietnam War, and still holds great significance to many of its descendants. Due to its historical significance, the Terengganu State government plans to develop Bidong Island as a heritage tourism site and a new scuba diving destination.This book highlights the uniqueness of Bidong Island and its archipelago, paying particular attention to the biological aspect (which includes marine and terrestrial organisms) and the pollution status surrounding the island. These mainly focus on organisms of the open water and benthic ecosystems such as plankton, fishes, corals reef communities, crustaceans and foraminifera. In addition, we discuss terrene related topics, which includes tree diversity, lichens and also herpetofauna surrounding the Bidong Island. Indisputably an important topic, we also address the pollution status surrounding Bidong Island, with emphasis on heavy metals and its impact.Readers interested in the areas of environmental sciences should find this book appealing. This book can also be used by students and researchers when discussing about tropical environments on island ecosystems. We do hope that stakeholders that would partake in future interest of Bidong Island (particularly in tourism) are equally aware of the current health status of the island and would engage in conserving and sustaining the diversity and heritage of the archipelago for the benefit of the community. 

South Asia, harboring the complex Himalayan terrains, has over one-fifth of the world's population and is recognized as the most hazard-prone region of the world. The exponential increase in population with the consequent pressure on natural resources and continued high rates of poverty and food insecurity also makes this region the most vulnerable region to hazards in the world as far as the impacts of climate change are concerned. Over the last century, the climatic trends in South-Asia have been observed to be characterized by increasing air temperatures and an increasing trend in the intensity and frequency of extreme events. IPCC (2014) has reported that the Himalayan highlands shall face significant warming over the next century. The increasing frequency of natural hazards due to the impacts of climate change in the Himalayas calls for efficient management and policymaking in these regions, which can only be implemented by the local governments through an established science-based robust action plan.This edited volume focuses on the management of natural hazards using innovative techniques of spatial information sciences and satellite remote sensing. It contains chapters from eminent researchers and experts in the field of hazard management, remote sensing, and GIS. The primary focus of this book is to replenish the gap in the available literature on the subject by bringing the concepts, theories, and practical experiences of the specialists and professionals in this field together in one volume to help students, researchers, and policymakers to address issues concerning management and policy implications of natural hazards in the complex Himalayan region.

This volume provides a versatile introduction to the study of drainage basin evolution, morphology, drainage basin hydrology and sedimentology, human interference, natural and anthropogenic hazards and various management techniques. This book offers the responsible factors of sediment yield and their absolute and specific growth and rate of delivery through tributaries to the main streams. Rivers are important geomorphic agents which reflect an amazing variety of form and behaviour, showing the wide range of natural environment in which they are originated.  The drainage system evolution and spatial network development within the dynamic nature are being discussed and how they are adjusted in the geomorphic time scale over the millions of years. This book shows how drainage systems function and react to change and why this thoughtful is required for flourishing integrated basin management. In tropical and sub-tropical countries population pressures as well as different developmental projects are being executed on the drainage basin without proper planning. Today scientists consider drainage basin as an administrative unit during implementation of regional projects. In this context this book will carry a bench mark for scholars and young scientists.

This edited book summarizes numerous research studies on remote sensing and GIS of natural resource management for the Himalaya region done by Indian Institutions and Universities over the last decade. It gives an overview of hydrometeorological studies on Himalayan water resources and addresses concerns in the development of water resources in this region, which is dealing with an increased pressure in population, industrialization and economic development. While the source of some of the major rivers of India are found in the Himalayas, the glaciers and water bodies in the region are continuously shrinking leading to a depletion of water and deterioration of water quality. This is affecting a population of up to 2.5 billion people. The ecosystems have been under threat due to deforestation, loss of biodiversity, expansion of agriculture and settlement, overexploitation of natural resources, habitat loss and fragmentation, poaching, mining, construction of roads and large dams, and unplanned tourism. Spaceborne remote sensing with its ability to provide synoptic and repetitive coverage has emerged as a powerful tool for assessment and monitoring of the Himalayan resources and phenomena. This work serves as a resource to students, researchers, scientists, professionals, and policy makers both in India and on a global level.
