"Climate Change and Island and Coastal Vulnerability is the outcome of a selection of peer reviewed edited papers presented at the International Workshop on Climate Change and Island Vulnerability (IWCCI) held at Kadmat Island, Lakshadweep, India in October 2010. Marine and coastal biodiversity, sea level rise vulnerability, fisheries, climate change impact on livelihood options, water and sanitation in island ecosystem and mitigation, adaptation and governance are the focal themes. The basic concept conveyed in the book is that biodiversity of islands is to be protected as a natural mechanism to mitigate climate change. Probability recurrence of mass coral bleaching and the management of coral reefs and their future protection are discussed in this book. Marine productivity and climate change for the last ten thousand years in the Arabian Sea have been examined with core records. Green technology is suggested as an important tool for mitigation and adaptation programmes in climate change. Measures taken to project biomass utilisation of islands as an energy source is delineated. Climate change may pose a potential threat on human health. Improved sanitation packages and models that are cost effective and environment-friendly for islands are uniquely presented in this book."

This book offers a meaningful and practicable guide to better management of arsenic problems in the groundwater of the Gangetic Plain. It gathers contributions from distinguished researchers who have been actively working in the area for over a decade. The arsenic contamination of groundwater is a growing concern in the central Gangetic Plain, where the local population's main sources of fresh water are surface water, groundwater and rain water; of these sources, only the last two generally meet the most important criteria for drinking water in their natural state. Natural geological changes are presumed to be the primary reason for arsenic contamination in this region. Further, most of the people living in this area have developed the habit of drinking water (groundwater) from the arsenic-contaminated tubewells in many parts of the region. As a result, many are suffering from arsenicosis and many more are at risk. Since the cause of arsenic contamination in groundwater still remains unclear, this book seeks to address the arsenic issue in this region by pursuing a holistic and systematic scientific approach. Accordingly, it delineates various sources, processes, hypotheses and remedial approaches that are needed to manage the arsenic contamination in the Central Gangetic Plain.
