This book explores the concept and issues of sustainability and its symbiotic relationship with existing water resources, the surrounding climate and geospatial development. It covers many dimensions of sustainable water resources, climatic variability, change. It also includes case studies on the basis of specific problems and issues, providing sustainable solutions for the future of the earth.Over the past several decades, climate change has significantly impacted a number of components of the hydrological cycle and hydrological systems, including changes in precipitation patterns and intensity; widespread melting of snow and ice; increased atmospheric water vapour; increased evaporation; and changes in soil moisture and runoff. Excess runoff eventually reaches larger bodies of water such as lakes, estuaries and the ocean, contaminating the water supply and limiting human and environmental access to water. An improved understanding of how changing anthropogenic activities could affect water resources, and climate in various parts of the world is a necessary step towards sustainability. This awareness requires analyses of challenging interactive areas within the geosphere, biosphere, hydrosphere, cryosphere and sociosphere, as resultant long-term sustainable strategies and measures are greatly needed.

The Bay of Bengal is prone to tropical cyclones and storm surges as a result of its location, and many of the mostly poor people living along the coastal regions of South Asia lose their lives almost every year. These disasters have been particularly devastating and have caused serious damage. During the past five decades, the low-lying coastal and offshore islands have experienced a tragic history of 50 severe cyclones and storm surges, with more than one million victims dead or missing. People accepted and waited for the next disaster as they had no alternatives. Members of the poor families who survived the disasters experienced hard times recovering from damage and the loss of their loved ones. After disasters, epidemic diseases arise in the affected areas. Many of the people in distress are also deprived of public services. Providing all sorts of assistance and emergency health preparedness are most essential to overcome such a situation. The causes of these huge casualties have been mainly: (1) the high population density of costal settlements, (2) inadequate cyclone shelters in the disaster risk areas, (3) lack of awareness of the disaster risk by the vulnerable population, (4) deterministic attitudes of people who accept disasters as "e;fate"e;, (5) houses that are weakly constructed and (6) underdeveloped central awareness programmes and weather forecast systems. This book is based on an empirical study presenting a timeline analysis of major cyclones and their impacts and consequent losses through the super-cyclones in the disaster-prone coastal regions of India, Sri Lanka and Bangladesh. This study also investigates resilience mechanisms based on early warning systems, technology applications including GIS and remote sensing, best practices, success stories and case studies that can be used for effective cyclone management and development of a resilience mechanism among coastal communities.
