The COVID-19 and the onslaught of Climate Change have exposed the fragility of our lives and ecosystem. Natural disasters like asteroid impact, earthquakes, tsunamis, volcanic eruptions, floods, cyclones, etc., and pandemics like plagues, smallpox, cholera, tuberculosis, malaria, etc., have been man's nemesis from the beginning of time. This list of public risks has now expanded to include pollutions, industrial disasters, and very many new, confusing and emerging technologies.How have governments handled these public risks? How have they convinced people to take precautions under such emergencies? What measures does one take for managing them, and for the rescue, relief, and rehabilitation of the masses? And most importantly, how does one prepare the masses to face the risks without panicking? It is argued that sermons, dictates, and discourses may not work in democratic societies. Rather, one needs a new breed of risk communicators who can enter into a dialogue with the people to prepare them for these challenges and to welcome truly beneficial new technologies.The book takes a panoramic view of the issue of risks and illustrates the challenges and opportunities of the Art and Science of Managing Public Risks. It celebrates the indomitable spirit of man, who has leveraged science to predict - where possible, and provide solutions for managing these risks.

The objective of the book is to make a comprehensive documentation of the observed variability and change of the regional climate system over the Indian region using the past observed data. The book addresses all the important parameters of regional climate system so that a physically consistent view of the changes of the climate system is documented. The book contains 16 chapters written by the subject experts from different academic and research institutes in India. The book addresses all important components/parameters of the climate system, like rainfall, temperature, humidity, clouds, moisture, sea surface temperature and ocean heat content, sea level, glaciers and snow cover, tropical cyclones and monsoon depressions, extreme rainfall and rainstorms, heat waves and cold waves, meteorological droughts, aerosols, atmospheric aerosols, ozone and trace gases and atmospheric radiative fluxes. One chapter deals with the past monsoon using monsoon proxy data. The last chapter deals with the future climate change projections over the Indian region (rainfall and temperature) made using coupled climate models. Most of the analyses (especially on rainfall, temperature, extreme rainfall, sea surface temperature, meteorological droughts) are based on the data for a longer period of 110 years, 1901-2010. For some other parameters like moisture, clouds, heat waves and cold waves, atmospheric aerosols, ozone and trace gases and radiative fluxes, data of shorter period have been used. The articles documented inter-annual and decadal variability in addition to documenting long term trends of different parameters. The trends have been tested for statistical significance using standard techniques. It is expected that the present book will be an excellent reference material for researchers as well as for policy makers. These results will be useful in interpreting future climate change scenarios over the region being projected using coupled climate models. Further analysis of these results is required for attributing the observed variability and change to natural and anthropogenic activities.

Lessons learned in the last several years have given clear indications that the prediction and efficient monitoring of disasters is one of the critical factors in decision-making process. In this respect space-based technologies have the great potential of supplying information in near real time. Earth observation satellites have already demonstrated their flexibility in providing data to a wide range of applications: weather forecasting, person and vehicle tracking, alerting to disaster, forest fire and flood monitoring, oil spills, spread of desertification, monitoring of crop and forestry damages.

This book focuses on a wider utilisation of remote sensing in disaster management. The discussed aspects comprise data access/delivery to the users, information extraction and analysis, management of data and its integration with other data sources (airborne and terrestrial imagery, GIS data, etc.), data standardization, organisational and legal aspects of sharing remote sensing information.
