This is a detailed and comprehensive study of the climates of Southern Asia, describing and interpreting the complex atmospheric dynamics of the region and explaining in depth the intricacies of the meteorology of the monsoon. To create this landmark study, the authors have made extensive and original use of the great wealth of primary data available, which has never previously been presented in such an integrated way. This book is organized in two parts. The first provides the essential meteorological background to understanding the South Asian climate. It places the regional circulation in the perspective of tropical general circulation and then describes the specific features that dominat...
This volume commemorates the Golden Jubilee Year of the establishment of Kirorimal College. This prestigious institution was honoured by the gracious presence of the First President of India, Dr. Rajindra Prasad who laid the foundation of the college building.This commemorative volume focuses attention on the growing awareness about plant ecology and environment biology. The different contributions present an up-to-date, detailed and balanced overview of the current knowledge within specific topics.Man has interacted with nature in various ways since the dawn of civilization. Primitive societies ensured that a proper balance was maintained. The situation has changed by the various developmen...
This book addresses an important topic of food security in South Asia with specific reference to climate change. Of the 1 billion food insecure people in the world, more than 30% are in South Asia. The problem of food insecurity may be exacerbated by the projected climate change especially because of the water scarcity caused by rapid melting of the glaciers in the Himalayas and increase in variability in monsoonal rains and frequency of extreme events. Furthermore, large populations of Bangladesh and other coastal regions may be displaced by sea level rise. Thus, this volume addresses recommended land use and soil/water/crop/vegetation management practices which would enable land managers to adapt to climate disruption by enhancing soil/ecosystem/social resilience. In addition to biophysical factors, this book also addresses the issues related to human dimensions including social, ethnical and political considerations.
The major challenges of the 21st century faced by human beings are how to achieve water security, food security, energy security and environmental security. Owing to enhanced natural/anthropogenic disasters worldwide, these challenges become much more complicated and daunting especially for developing countries. Therefore, it is important to highlight the risk of different disasters as well as the modern tools and techniques for minimizing disaster incidence and losses. Disaster management being highly multidisciplinary in nature, a comprehensive book dealing with different aspects of disaster management, and encompassing important disasters faced by humankind is presently not available. This book is an attempt to fulfill this gap. It provides clear, comprehensive, and up-to-date information about different facets of disaster management along with salient case studies. The book highlights the current status of disaster management focusing on developing nations, discusses vital issues such as climate change and sustainable development, modern approaches and tools/techniques, and the challenges of and future R&D needs for sustainable disaster management.
This open access book discusses the impact of human-induced global climate change on the regional climate and monsoons of the Indian subcontinent, adjoining Indian Ocean and the Himalayas. It documents the regional climate change projections based on the climate models used in the IPCC Fifth Assessment Report (AR5) and climate change modeling studies using the IITM Earth System Model (ESM) and CORDEX South Asia datasets. The IPCC assessment reports, published every 6–7 years, constitute important reference materials for major policy decisions on climate change, adaptation, and mitigation. While the IPCC assessment reports largely provide a global perspective on climate change, the focus on...
This volume provides an interdisciplinary collection of studies that cover the trends and issues related to agricultural productivity and availability, food and nutrition security, and sustainability in India. The book discusses a broad range of vital issues concerning the production and consumption of food during the era of climate change, and has been prepared to generate awareness of these issues in a large agricultural economy to shed light on new perspectives and solutions to achieve sustainable food production and security in India. The book is organized into three major sections: Climate and Agricultural Productivity for Availability, Changes and Trends in Cropping Patterns and Food Security, and Food and Nutrition Security for Sustainable Development. The book will be of interest to students, researchers, policymakers, and other inquisitive readers interested in different aspects of agriculture, food and nutrition security, and sustainable development.
This book proposes a unique and comprehensive integrated synthesis of the current understanding of the science of Himalayan dynamics and its manifestations on physical systems and ecosystems at different spatial and temporal scales. In particular, this work covers relevant aspects of weather and climate, paleoclimate, snow, glacier and hydrology, ecology/forestry among other topics associated with the Himalayas. It highlights the role of the Himalayas in defining local to regional to global scale impact on weather and climate. It includes Himalayan impact on defining physical basis of changing glacier systems, permafrost melting/thawing, climate variability, and hydrological balances. As a result, this volume represents an important synthesized overview both for environmental and earth science researchers, and for policy makers and stakeholders interested in the physical and dynamical processes associated with the Himalayan massif.
Global environmental change occupies a central niche in the pantheon of modern sciences. There is an urgent need to know and understand the way in which global biogeochemical cycles have changed over different time scales in the past and are likely to do so in the future. Equally important, it is necessary to determine the extent to which natural variability and that induce by anthropogenic activities are bringing about change. A number of international co-operative scientific programmes ad dress these issues. Chief among them are the International Geosphere-Biosphere Programme (IGBP), the World Climate Research Programme (WCRP) and the Inter national Human Dimensions Programme (IHDP) for gl...
Completely devoted to applicati on of models to opti mize the use of limited water and nutrients in various climates, this collecti on will inspire confi dence in the capacity of modeling to tackle the biggest threats to secure agriculture. To obtain the most producti on from available water while maintaining natural resources, we need whole system–based quanti tati ve knowledge and tools to help select appropriate crops and manage water and associated inputs on a site-specifi c basis under changing climate. Site-specifi c experimental results are available for limited locati ons, limited periods of ti me, and limited management opti ons. Well-tested process models of cropping systems can extend fi eld research results to long-term weather conditi ons, as well as other climates and soils, allowing us to explore new management opti ons. The case studies in this volume are promising examples of these kinds of soluti ons.
