South Asia constitutes a key geography in the world today considering its large population and related daunting energy and environmental challenges. Many countries in the region are faced with a growing gap between energy demand and local resources, resulting in an increased dependence on imports. According to the International Energy Agency (IEA), the energy demand in South Asia will grow at a rate more than double that of the world average in the coming decades. This book addresses the critical subject of energy and environmental outlook for South Asia and presents the wider challenges and the responses at the national and regional level. Features: Discusses and addresses the ongoing energy and environmental challenges faced by almost a quarter of the global population Includes dedicated chapters for each country and presents analysis and recommendations by regional experts Examines how deteriorating air quality and persistent natural disasters are severe environmental challenges for the region Discusses the implications of global warming and climate change for South Asia Includes practical case studies throughout Energy and Environmental Outlook for South Asia will benefit a wide range of stakeholders from various fields including but not limited to energy, environment, economics, national security, and sustainable development. It also serves as a valuable resource for academics, researchers, analysts, policymakers, and representatives of utilities, industry, professional bodies, financial institutions, think tanks, and developmental organizations to better plan their initiatives, activities, and policies. It will help countries in the region and also those around the world by learning from shared experience, and ideally by collaborating for energy and environmental prosperity.

Studies on South Asia are an emerging interdisciplinary field, this volume expands on the currently limited literature available on South Asia and focuses on the regions environmental, climatic and natural resource base by looking at case studies from Nepal, India and Bangladesh. The book contains twelve chapters which deal with various environmental challenges, such as the impacts of climate change on floods and droughts, population structure and regeneration dynamics of dominant treeline species, environmental changes and rural livelihoods, and change analysis and impacts of hard coastal structures. Apart from the various thematic areas and diversity of geographical coverage, most of the studies also demonstrate the application of geospatial techniques for the collection of environmental data, and the use of GIS for spatial analysis of the data. The specific application of geospatial techniques and methods includes NDVI, NDWI, NDBI, SMI, SPOT-VGT NDVI, environmental flow, distribution and trend estimation of tropospheric formaldehyde, vegetation sensitivity to climate change, variability of tropospheric ozone, and geo-environmental problems. The contributors are seasoned researchers currently engaged in academic and research activities, and work at universities in USA, India, Bangladesh, Bhutan and Japan.

A comprehensive introduction to the important economic, social and political processes and development issues in this extremely popular region. South Asia provides one of the world's most challenging development contexts and The authors take a different approach to most traditional development texts, making the latest research teacher friendly and presenting material in an accessible manner for non-specialists.

This book provides a comprehensive and interdisciplinary examination of the diverse aspects of climate change in South Asia. The region, home to almost 4% of the world’s population, is under serious threat from climatic disasters. The volume underscores the urgency of addressing cataclysmic events related to climate change and their ramifications on the economy, agriculture and livelihoods of the region. The book discusses the reasons causing climate change as well as highlights normative and ethical considerations involved in the battle against climate change. With case studies from India, Sri Lanka and Bangladesh, it explores issues such as extreme climatic events; energy use, fossil fuels, non-renewable resources and carbon dioxide emission in South Asia; internal migration and climate refugees; the ethical dilemma of sustainable development; technological advancements for extreme weather forecast; and responses to climate change in South Asia. Highlighting the need for striking a balance between developmental imperatives and environmental sustainability, the chapters also show the North-South divide in the research agenda and policies on climate change and the global politics that underlie climate policies. The volume juxtaposes a scientific analysis of factors responsible for climate change with an analysis of the human cost of climate change from the perspective of social sciences. It discusses the challenges faced by developing countries while also offering recommendations and solutions. This book will be of interest to scholars and researchers of climate studies, geography, public policy and governance, sustainable development, development studies, environmental studies, political studies, international relations, political economy, economics and sociology. It will also be useful to practitioners, thinktanks, policymakers and civil society organisations working on environmental management.

This book, through a bunch of systematic and analytical notes and scientific commentaries, acquaints the readers with the innovative methods of regional development, measurement of the development in regional scale, regional development models, and policy prescriptions. Conceptualizing development as a regional process is a geographer's brainchild, and the sense of region has long been rooted deeply in the fundamental research practices that geographers are accustomed to. The geographical perspective of regions entails conceptualizing them nested horizontally as the formal region and hierarchical relationships in space with spatial flows or interactions as the functional region. In geographical research, the region works as a tool by serving as a statistical unit of analysis. More importantly, however, regions serve as the fundamental spatial units of management and planning by specifying a territory or a part of it for which a certain spatial development or regulatory plan is sought. This book addresses the complex processes in different regions of the world, particularly South Asia, to perceive the regional development planning involved and the sustainable management practiced there. The book is a useful resource for socio-economic planners, policymakers, and policy researchers.

The Fourth Assessment Report of IPCC having clinched in 2007 the evidence of global warming on account of anthropogenic activities, backed with scientific data gathered and analyzed globally, has made it mandatory world over to focus efforts on delineation of the anticipated adverse impacts of global warming on regional temperature and moisture regimes and the linked hydrologic, climatic and biospheric processes. First and foremost is the requirement to understand vulnerability to food and livelihood security in various ecosystems—on mainland, mid-range and high mountains as well as coastal areas including CEZs. The projected global temperature rise of the order of about two degrees or more and further rise at a decadal rate of o around 0. 2 C is sufficient to make grievous changes in sea surface level and submerge many low lying coastal areas around the world thereby possibly causing unprecedented losses to human habitat and livelihood in the coming years. A rise in climate variability is also becoming increasingly evident with potential direct impact on agricultural performance, on water accessibility and on weather extremes. Developing countries due to their poor infrastructure, limited resources and large impoverished population are likely to face more intense and wi- spread adverse impact of climate change than the developed world and also have limited adaptation capacity.
