Arsenic in PlantsComprehensive resource detailing the chemistry, toxicity and impact of arsenic in plants, and solutions to the problemArsenic in Plants: Uptake, Consequences and Remediation Techniques provides comprehensive coverage of the subject, detailing arsenic in our environment, the usage of arsenicals in crop fields, phytotoxicity of arsenic and arsenic's impact on the morphology, anatomy and quantitative and qualitative traits of different plant groups, including their physiology and biochemistry. The work emphasizes the occurrence of arsenic, its speciation and transportation in plants, and differences in mechanisms of tolerance in hyper-accumulator and non-accumulator plants.Throughout the text, the highly qualified authors delve into every facet of the interaction of arsenic with plants, including the ionomics, genomics, transcriptomics and proteomics in relation to arsenic toxicity, impact of exogenous phytohormones and growth-regulating substances, management of arsenic contamination in the soil-plant continuum, phytoremediation of arsenic toxicity and physical removal of arsenic from water. General discussion has also been included on subjects such as the ways through which this metalloid affects plant and human systems.Topics covered include:* Introduction and historical background of arsenic and the mechanism of arsenic transport and metabolism in plants* Arsenic-induced responses in plants, including impact on biochemical processes and different plant groups, from cyanobacteria to higher plants* The role of phytohormones, mineral nutrients, metabolites and signaling molecules in regulating arsenic-induced toxicity in plants* Genomic, proteomic, metabolomic, ionomic and transcriptional regulation during arsenic stress* Strategies to reduce the arsenic contamination in soil-plant systems and arsenic removal by phytoremediation techniquesResearchers, academics, and students of plant physiology, biotechnology, and agriculture will find valuable information in Arsenic in Plants to understand this pressing subject in full, along with its implications and how we can adapt our strategies and behaviors to promote reduced contamination through practical applications.

A comprehensive guide to managing and mitigating natural disastersRecent years have seen a surge in the number, frequency, and severity of natural disasters, with further increases expected as the climate continues to change. However, advanced computational and geospatial technologies have enabled the development of sophisticated early warning systems and techniques to predict, manage, and mitigate disasters.Techniques for Disaster Risk Management and Mitigation explores different approaches to forecasting disasters and provides guidance on mitigation and adaptation strategies.Volume highlights include:* Review of current and emerging technologies for disaster prediction* Different approaches to risk management and mitigation* Strategies for implementing disaster plans and infrastructure improvements* Guidance on integrating artificial intelligence with GIS and earth observation data* Examination of the regional and global impacts of disasters under climate variability
