    Natural and Technological Hazards in Urban Areas

    Get PDF
    Natural hazard events and technological accidents are separate causes of environmental impacts. Natural hazards are physical phenomena active in geological times, whereas technological hazards result from actions or facilities created by humans. In our time, combined natural and man-made hazards have been induced. Overpopulation and urban development in areas prone to natural hazards increase the impact of natural disasters worldwide. Additionally, urban areas are frequently characterized by intense industrial activity and rapid, poorly planned growth that threatens the environment and degrades the quality of life. Therefore, proper urban planning is crucial to minimize fatalities and reduce the environmental and economic impacts that accompany both natural and technological hazardous events

    Decolonizing energy transitions. The political economy of low-carbon infrastructure, justice, extraction and post-development in the Southeast of Mexico.

    This thesis examines socioecological and onto-epistemic conflicts over low-carbon infrastructure in Yucatan, Mexico. Focusing on how energy systems and policies reconfigure landscapes and vice versa, it offers an expanded view of the broader social, political, historical, economic and environmental implications of such a transformation at different scales. It argues that the reconfiguration of landscapes is mediated by a capitalist drive towards the exploitation of so-called superabundance of 'renewable energy potential' where othered territorial relationships are made invisible or seen as ‘waste’ as they are tied-in to a particular epistemology of development. This thesis draws on the analysis of Critical Political Ecology on energy transitions, on the decolonial turn and the rise of extractivism in Latin America and on the work of political ecology and ontology, which has open broader questions about how certain notions such as ‘energy’, ‘transitions’ and ‘justice’ are understood. Drawing on these contributions, this thesis argues that geographers and critical scholars must pay closer attention to low-carbon infrastructure and the transition process, not only transcending the limited and simplified fossil fuel vs. renewable energy dichotomy that shapes the hegemonic energy transition, but in their analysis of how energy systems operate around Eurocentric and universal formulations of knowledge, power and being. The thesis seeks to make a contribution to how researchers, activists and policy-makers engage with the notion of energy justice arguing for a pluriversal and relational understanding of energy and of the process of transforming energy systems

    Information Refinement Technologies for Crisis Informatics: User Expectations and Design Implications for Social Media and Mobile Apps in Crises

    Get PDF
    In the past 20 years, mobile technologies and social media have not only been established in everyday life, but also in crises, disasters, and emergencies. Especially large-scale events, such as 2012 Hurricane Sandy or the 2013 European Floods, showed that citizens are not passive victims but active participants utilizing mobile and social information and communication technologies (ICT) for crisis response (Reuter, Hughes, et al., 2018). Accordingly, the research field of crisis informatics emerged as a multidisciplinary field which combines computing and social science knowledge of disasters and is rooted in disciplines such as human-computer interaction (HCI), computer science (CS), computer supported cooperative work (CSCW), and information systems (IS). While citizens use personal ICT to respond to a disaster to cope with uncertainty, emergency services such as fire and police departments started using available online data to increase situational awareness and improve decision making for a better crisis response (Palen & Anderson, 2016). When looking at even larger crises, such as the ongoing COVID-19 pandemic, it becomes apparent the challenges of crisis informatics are amplified (Xie et al., 2020). Notably, information is often not available in perfect shape to assist crisis response: the dissemination of high-volume, heterogeneous and highly semantic data by citizens, often referred to as big social data (Olshannikova et al., 2017), poses challenges for emergency services in terms of access, quality and quantity of information. In order to achieve situational awareness or even actionable information, meaning the right information for the right person at the right time (Zade et al., 2018), information must be refined according to event-based factors, organizational requirements, societal boundary conditions and technical feasibility. In order to research the topic of information refinement, this dissertation combines the methodological framework of design case studies (Wulf et al., 2011) with principles of design science research (Hevner et al., 2004). These extended design case studies consist of four phases, each contributing to research with distinct results. This thesis first reviews existing research on use, role, and perception patterns in crisis informatics, emphasizing the increasing potentials of public participation in crisis response using social media. Then, empirical studies conducted with the German population reveal positive attitudes and increasing use of mobile and social technologies during crises, but also highlight barriers of use and expectations towards emergency services to monitor and interact in media. The findings led to the design of innovative ICT artefacts, including visual guidelines for citizens’ use of social media in emergencies (SMG), an emergency service web interface for aggregating mobile and social data (ESI), an efficient algorithm for detecting relevant information in social media (SMO), and a mobile app for bidirectional communication between emergency services and citizens (112.social). The evaluation of artefacts involved the participation of end-users in the application field of crisis management, pointing out potentials for future improvements and research potentials. The thesis concludes with a framework on information refinement for crisis informatics, integrating event-based, organizational, societal, and technological perspectives
