This book offers essential insights into potential catastrophic events that might befall upon the emerging urban landscape in South Asia, and which are due to hazards, risks and vulnerabilities inherent in the region’s geophysical location, as well as due to climate change and unplanned urbanization. It highlights major physio-graphic, demographic, geological and geophysical indicators that are responsible for changing the pattern and trend of urbanization in South Asia – a crucial issue in view of emerging threats of climate change, and changes in the demographic profile. The book addresses the disaster management scenario in South Asia, manifestations of climate change in the region and various urban setups under climate-change-induced risks. Further, it elaborates on the challenges of urbanization-based neo-risks and vulnerabilities, which manifest in the form of slum area growth, piling and littering of waste and filth, new health risks, groundwater contamination, air pollution, highly energy-dependent lifestyles, poverty, socio-economic tensions, etc. It also critically examines the institutional mechanisms for disaster risk reduction (DRR), climate change adaptation (CCA) and urban governance, and suggests appropriate changes in the governing structure to mitigate these risks. The book draws the attention of urban planners and policymakers to current shortcomings in the administrative and financial structures of local urban bodies. While outlining climate-associated risks and adaptation strategies in South Asia, it also suggests measures for integrating climate change and urban adaption with state's planning processes, and puts forward a risk alleviation platform to bring the risk managers working in different fields together, so that they make concerted efforts to achieve sustainable development. It offers valuable takeaways for researchers, urban planners, those working in industry, consultants, and policymakers.

Contamination of aqueous environments by hazardous chemical compounds is the direct cause of the decline of safe clean water supply throughout the globe. The use of unconventional water sources such as treated wastewater will be a new norm. Emerging nanotechnological innovations have great potential for wastewater remediation processes. Applications that use smart nanomaterials of inorganic and organic origin improve treatment efficiency and lower energy requirements. This book describes the synthesis, fabrication, and application of advanced nanomaterials in water treatment processes; their adsorption, transformation into low toxic forms, or degradation phenomena, and the adsorption and separation of hazardous dyes, organic pollutants, heavy metals and metalloids from aqueous solutions. It explains the use of different categories of nanomaterials for various pollutants and enhances understanding of nanotechnology-based water remediation to make it less toxic and reusable.

This edited book provides an overview of omics technologies and methods for integration across multiple omics layers used in the plant disease diagnosis and developing management strategies. The book concentrates on the prevalence of soil-borne disease management in various important crops with use of different strategies, including host resistance and biological control etc. The special focus is on the resolving practical problems encountered after the resistance development in the pathogens against several chemical pesticides. Further, special attention is given to the emergence of new diseases or the re-emergence of old ones on several crops, and on the results and problems encountered by using microbial inoculants, biofumigation and other non-chemical control methods. This book has 18 contributory chapters from the eminent experts in the field of plant pathology, microbiology and biotechnology working on different aspects of soil-borne diseases of important agricultural crops. This edited volume is of interest and useful to researchers in plant pathology, agriculture sciences, plant genomics ecology, policy makers, also it is a valuable source of reference to the relevant researchers and students globally.
