The management of data to understand complex and interwoven processes of sustainable development has been a great challenge for researchers, planners, and decision makers. Remote sensing and GIS-based policy decision support systems not only help them to solve spatially related environmental and socio-economic issues; they also provide a powerful tool for integrating spatial and non-spatial datasets with analytical and spatial models and knowledge domains. Recent advances in the modern spatial tools of remote sensing and GIS combined with advanced computation techniques have enhanced the efficiency and capabilities of policy development. This book expands the scientific knowledge base in various physical and socio-economic issues among scholars, planners, and decision makers for policy development and research regarding sustainable development. It also demonstrates the importance of modern spatial decision support tools of remote sensing and GIS to better understand sustainable development processes and policy development. Furthermore, the book discusses case studies providing new insights as to how remote sensing and GIS-based decision support systems contribute to understanding physical and socio-economic processes and developing pragmatic policy for sustainable development.This book covers land surface temperature, hydrological processes, terrain mapping, flood and landslide hazards, land use and land cover dynamics, crime hotspots, urban health issues, tourism, agriculture, forest management, flood mitigation, urban sprawl, and village information systems, among others. Readers will find this book to be an invaluable resource for understanding and solving diverse physical and human issues for policy development related to sustainable planning and management.

The world is currently experiencing changes in climate and environment that often lead to natural disasters. Nearly three million people worldwide may have been killed in the past 20 years by natural disasters. In total, 90% of the natural disasters and 95% of all disaster-related deaths occur in the developing countries. Recently such problems have accelerated due to LULC change, biodiversity degradation, increased tourism, urbanization and climate change. This book, consisting of 27 chapters, explores the topics of climate, environment and natural disasters in developing countries. It is essential to discuss these diverse issues in the field of geography as it encompasses interdisciplinary topics. The range of issues on national, regional and local dimensions is not only confined to geography but also concerned to other disciplines as well. Therefore, this book is a valuable source for scientists and researchers in allied fields such as climatology, disaster management, environmental science, hydrology, agriculture, and land use studies, among other areas. Furthermore, this book can be of immense help to the planners and decision-makers engaged in dealing with the problems of climate, environmental change and natural disasters in developing countries.

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.

Agriculture is the backbone of our economic system. It provides not only food and raw material but also employment opportunities to a very large number of people. Higher atmospheric temperature has an impact on crop yields while the changes in rainfall could affect both crop quality and quantity. Climate change, therefore, could increase the prices of major crops in some regions. For the most vulnerable people, lower agricultural output means lower income. In addition, climate change is expected to increase the risk of illness and death from extreme heat and poor air quality. Recent evidence is the COVID-19 pandemic. Furthermore, climate change also affects the occurrence of other infectious diseases. A number of well-known diseases are climate-sensitive - malaria, dengue fever, and cholera among others. Tourism is considered as an industry and alternative contributor to a nation¿s income. It can generate employment opportunities and boost up the economy. This book, consisting of 26 chapters, focuses on the issues of agriculture, tourism and health for livelihood enhancement. It is essential to discuss these diverse issues in the field of geography as it encompasses interdisciplinary topics. The range of concerns at the national, regional and local levels is not confined to geography only but also involves other disciplines as well. Therefore, this book is a valuable source for scientists and researchers in allied fields such as livelihood, agriculture, land use, tourism management, health care and tribal studies. Furthermore, this book can be of immense help to the researchers, planners and decision makers engaged in solving problems in these areas in developing countries and beyond.
