Monitoring and Managing Multi-hazards: A Multidisciplinary Approach (GIScience and Geo-environmental Modelling)

by Jayanta Das Sudip Kumar Bhattacharya

​To monitor multi-hazards, Remote Sensing and GIS-based multi-criteria decision-making (MCDM) techniques have been extensively used in recent years worldwide. Since natural hazards cannot be eliminated, only quantification of these events and reliable forecasting can alleviate their detrimental effects, through which we can build more resilient and safe societies. Moreover, cultivating the proper knowledge of the multi-hazards and their monitoring and management can fill the gap between science, policy, and the community concerned. In an endeavor to understand and characterize the various hazards, Monitoring and Managing Multi-hazards: A Multidisciplinary approach presents a synthesis of what cross-disciplinary researchers know about these hazards and indigenous adaptation strategies.The book therefore focuses on the use of precision techniques, Remote Sensing, and GIS technologies to quantify various natural, environmental and social hazards along with the capacity building and sustainable mitigation strategies towards resilient societies. It encompasses both thematic and regional case studies to highlight the dynamicity of climate change, change of natural resources, landscape, water, river, agricultural, and social ecosystems at various spatio-temporal scales, including theoretical and applied aspects. The book gives readers an overview and analysis of traditional and advanced geospatial technologies on atmospheric, lithospheric, hydrosphere, biospheric and socio-economic contexts, on all spatial and temporal scales regarding hazards and disasters and sustainable development and management for the future.
