‘Citizen sensing’, the practice in which grassroots actors use sensor technology for environmental monitoring, is increasingly entering the debate around environmental risk governance. This groundbreaking book explores the potential for citizen sensing to concretely influence the governance of environmental risks to public health by shaping policy responses implemented by competent institutions.

This book focuses on monitoring and assessing various environmental processes in Tunisia using state-of-the-art remote sensing and GIS technologies. In addition to addressing the diversity of Tunisian landscapes and providing spatial analysis of natural, cultivated and urbanized environments. It presents and discusses several case studies on integrated RS / GIS approaches for mapping, modeling, monitoring and evaluation. Moreover, in this volume authored by experts in the topic from Tunisia and other countries, authors assess the agro-environmental applications from Tunisia and offer different methods and applications to environmental processes and risks including drought, degradation, flood, planning, Yield estimation, dust storm detection, dry land vulnerability, wetland dynamics and others. The material presented here will help decision-makers plan sustainable landscape and agricultural management policies that preserve biodiversity and contribute to achieving sustainability goals and for researchers, it will expose methodological approaches used in different fields of research. Graduate students and Practionioner engineers working in the field of RS/GIS will also benefit from the book. The book ends with a set of conclusions and recommendations to support researchers underscoring the need for further research in this area.

Remote sensing data and methods are increasingly being implemented in assessments of volcanic processes and risk. This happens thanks to their capability to provide a spectrum of observation and measurement opportunities to accurately sense the dynamics, magnitude, frequency, and impacts of volcanic activity. This book includes research papers on the use of satellite, aerial, and ground-based remote sensing to detect thermal features and anomalies, investigate lava and pyroclastic flows, predict the flow path of lahars, measure gas emissions and plumes, and estimate ground deformation. The multi-disciplinary character of the approaches employed for volcano monitoring and the combination of a variety of sensor types, platforms, and methods that come out from the papers testify to the current scientific and technology trends toward multi-data and multi-sensor monitoring solutions. The added value of the papers lies in the demonstration of how remote sensing can improve our knowledge of volcanoes that pose a threat to local communities; back-analysis and critical revision of recent volcanic eruptions and unrest periods; and improvement of modeling and prediction methods. Therefore, the selected case studies also demonstrate the societal impact that this scientific discipline can potentially have on volcanic hazard and risk management.

A timely exploration of how odor seeps into structural inequality Our sense of smell is a uniquely visceral—and personal—form of experience. As Hsuan L. Hsu points out, smell has long been spurned by Western aesthetics as a lesser sense for its qualities of subjectivity, volatility, and materiality. But it is these very qualities that make olfaction a vital tool for sensing and staging environmental risk and inequality. Unlike the other senses, smell extends across space and reaches into our bodies. Hsu traces how writers, artists, and activists have deployed these embodied, biochemical qualities of smell in their efforts to critique and reshape modernity’s olfactory disparities. The Smell of Risk outlines the many ways that our differentiated atmospheres unevenly distribute environmental risk. Reading everything from nineteenth-century detective fiction and naturalist novels to contemporary performance art and memoir, Hsu takes up modernity’s differentiated atmospheres as a subject worth sniffing out. From the industrial revolution to current-day environmental crises, Hsu uses ecocriticism, geography, and critical race studies to, for example, explore Latinx communities exposed to freeway exhaust and pesticides, Asian diasporic artists’ response to racialized discourse about Asiatic odors, and the devastation settler colonialism has reaped on Indigenous smellscapes. In each instance, Hsu demonstrates the violence that air maintenance, control, and conditioning enacts on the poor and the marginalized. From nineteenth-century miasma theory theory to the synthetic chemicals that pervade twenty-first century air, Hsu takes smell at face value to offer an evocative retelling of urbanization, public health, and environmental violence.

The contemporary world is characterized by the massive use of digital communication platforms and services that allow people to stay in touch with each other and their organizations. On the other hand, it is also a world with great challenges in terms of crisis, disaster, and emergency situations of various kinds. Thus, it is crucial to understand the role of digital platforms/services in the context of crisis, disaster, and emergency situations. Digital Services in Crisis, Disaster, and Emergency Situations presents recent studies on crisis, disaster, and emergency situations in which digital technologies are considered as a key mediator. Featuring multi- and interdisciplinary research findings, this comprehensive reference work highlights the relevance of society’s digitization and its usefulness and contribution to the different phases and types of risk scenarios. Thus, the book investigates the design of digital services that are specifically developed for use in crisis situations and examines services such as online social networks that can be used for communication purposes in emergency events. Highlighting themes that include crisis management communication, risk monitoring, digital crisis intervention, and smartphone applications, this book is of particular use to governments, institutions, corporations, and professionals who deal with crisis, disaster, and emergency scenarios, as well as researchers, academicians, and students working in fields such as communications, multimedia, sociology, political science, and engineering.

This collection of symposium papers covers such topics as: environmental change; desertification; rainfall; erosion and geomorphological hazards; and land degradation and marine pollution. Other presentations dealt with practical applications of remote sensing and geographic information systems.

The scope of image processing and recognition has broadened due to the gap in scientific visualization. Thus, new imaging techniques have developed, and it is imperative to study this progression for optimal utilization. Big Data Analytics for Satellite Image Processing and Remote Sensing is a critical scholarly resource that examines the challenges and difficulties of implementing big data in image processing for remote sensing and related areas. Featuring coverage on a broad range of topics, such as distributed computing, parallel processing, and spatial data, this book is geared towards scientists, professionals, researchers, and academicians seeking current research on the use of big data analytics in satellite image processing and remote sensing.
