Porto: Porto — Campanhã Collage. Stories from the City’s Edge
No full textCampanhã, the easternmost parish of the city of Porto, Portugal, is a land marked by problems of social and territorial cohesion, fractured by large-scale rail and road infrastructures, an area still torn between its past of rural tradition and the increasingly visible features of middle-class modernity with cosmopolitan aspirations. Campanhã Collage provides a kaleidoscopic overview of this area through four contributions based on the work of different projects with distinct methods, agendas and outputs, some of which focused on specific parts of the parish.
StreetArtCei, the first case, applies its method of digitally mapping street art routes to Campanhã, expressing specific cultural geographies and serving as a barometer of the city’s changing spaces. The Atlas of Literary Landscapes, the second case, proposes a collection of textual excerpts documenting the railroad and the Campanhã train station through Portuguese literature. The third case, The Worst Tours, an initiative of walking tours that offer a critical perspective of the city apart from mainstream routes, discusses and envisions possibilities of transformation. Its contribution includes coloured hand drawings, photos, and a poetic text, focusing specifically on Freixo, the riverfront area of Campanhã. Finally, A Drift in vacant Campanhã recounts the experience of URBiNAT, a project aimed to design opportunities to co-create an inclusive public space in these underutilized areas, together with local citizens and stakeholders.
Despite the evident differences in the nature of these projects, the juxtaposition of these stories and accounts provides alternative views of the fragmented territory of Campanhã. It also conveys a spatialized description of several of its multiple problems and possibilities. While not offering a comprehensive reading of this part of the city, the methods and fieldwork experiences used testify to the rich potential of each medium and allow for the construction of new meaningful itineraries. 
Osijek: Mapping the Fictional and the Physical City: The Spatiotemporal and Cultural Identity of Osijek, Croatia
No full textBecause of its status as the fourth largest city in Croatia, Osijek is considered an intermediate European city. It is the administrative, economic and cultural centre of eastern Croatia, located on the River Drava, and has a rich, multicultural history that is reflected in its tangible and intangible urban identity. It is famous for its historical Fort Tvrđa and its European Avenue, the most representative street of Austro- Hungarian Secession architecture, but also for its specific sociolects that have been a part of its everyday life. Within the COST Action Writing Urban Places: New Narratives of the European City, Osijek was host to the doctoral training school ‘Urban Chronicles in Empirical Context’ (April 2022) and a short-term scientific mission to investigate the ‘other’ perspectives of the city (August 2022). As events that fostered the training, research, and the networking of international and national young researchers, doctoral candidates and members of academia, they helped to raise awareness of the notion of urban identity of a city as a complex of its physical (geography, architecture, infrastructure) and ephemeral manifestations (literature, culture, history) through time. As such, the events functioned as an outreach, linking the involved participants to their own responsibilities to the city as potential and future policymakers. The following chapter focuses on elements of the city of Osijek as presented through the literary point of view of local authors from the mid-twentieth to the early twenty-first century. 
A historical perspective on water governance in Republic of Ireland
No full textThis paper provides a historical perspective on the evolution of water governance in the Republic of Ireland where long-term shifts in agricultural activities, demographic characteristics, water and debates over drinking water supply charges have influenced water resources governance and the integration of management practices. Drawing on threads from the past, the paper first describes how water governance from the early 1950s focused on rural access to water, pollution control and monitoring. With the advent of the Water Framework Directive in 2003, the crux of policy and management practices changed, with 81% of present policies mirroring Integrated Water Resource Management principles. However, issues such as the implementation of drinking water supply water charges and equitable access to water resources remain controversial. Looking to the future, the effects of climate change and land use planning, as well as demographic changes and international legislation are among those factors influencing water policy and management in the Republic of Ireland. Structured stakeholder engagement and further research directed at improving water quality is advocated to promote a sustainable and equitable water future
Cumulative Land Subsidence in Populated Asian Coastal Cities
Get PDFIn contrast to sea-level rise, which is often associated with climatic and environmental changes, land subsidence has largely been overlooked in discussions regarding future adaptation to higher sea water levels. In order to articulate the critical contribution of this phenomenon, this short paper provides a reliable chart that details land subsidence in densely populated East and Southeast Asian coastal cities. The causes of subsidence at these locations are also discussed based on existing literature. Land subsidence was observed to be one or two orders of magnitude faster than sea-level rise caused by an anthropogenic global warming, and can continue unabated unless its root causes are addressed through clear policies at the municipal level. Subsidence is clearly a localized problem, and is thus easily overlooked by regional or national governments. Nevertheless, once subsidence takes place it cannot be reversed, and hence it is crucial to rapidly formulate appropriate countermeasures when it is identified. The examples of these Asian cities demonstrate that, if subsidence is recognized and adequate policies are put in place and implemented, it can be brought under control in a fairly short period of time
The Potential for Various Riverine Flood DRR Measures at the Global Scale
Get PDFFlooding events that occur on the Earth’s rivers annually cause large amounts of monetary and human impacts. These impacts are expected to increase through the end of the 21st century for various reasons. Decision makers must take action now and implement disaster risk reduction measures to avoid large increases to damages in the future. On the global scale, we model three disaster risk reduction measures – namely dykes and levees, dry-proofing, and zoning restrictions – and evaluate them in terms of their economic performance (via benefit-cost analysis) as well as their ability to achieve a predefined risk reduction target based on current relative levels of risk, referred here to as efficacy. We show that large decreases to future expected annual damages can be obtained if certain measures are implemented throughout various sub-national regions of the world, most notably in regions with high levels of projected population growth. We see that the two aforementioned evaluation metrics, when used to select a disaster risk reduction measure for implementation, result in different outcomes for three-fourths of the world’s sub-national regions, most often in East Asia and the Pacific as well as South Asia. In these instances, decision makers must choose what is more important – achieving a risk reduction target, or having investments pay-off in the long run, even if it requires a large amount of up-front capital. This opens the dialogue for incorporating other non-monetary values into the decision making process for disaster risk management, and also points to the potential of hybridising riverine adaptation measures to achieve multiple risk and societal objectives at once
AI-Driven Identification of Contrail Sources: Integrating Satellite Observation and Air Traffic Data
Get PDFDespite large uncertainties, it is now clear that condensation trails play a major role in aviation contribution to climate change. In order to assess these uncertainties and reduce them, a database of observations needs to be built up to improve prediction models and to enable aircraft trajectories optimization based on climate considerations. In order to build this observations database satellite images are good candidates, but detecting contrails in images is a time-consuming task without automation. In this paper, a dataset from GOES-16 satellite images is used to create a detection algorithm based on segmentation methods. Then, a method is introduced for associating contrails with aircraft trajectories based on ADS-B data. The Hough transform and meteorological forecast reanalysis data are applied to link any contrail with a group of flights that may have contributed to its formation
[Poster] Aircraft Detection and State Estimation in Satellite Images
No full textUnidentified flying objects are aircraft that do not continuously broadcast ADS-B. They pose a risk to air traffic safety. In this study, we introduce a method for detecting and estimating the state of aircraft in Sentinel-2 multispectral satellite images. We construct a dataset of 579 ADS-B annotated aircraft from 69 Sentinel-2 images. A CNN is trained on the dataset to aircraft state vector i.e. position, velocity, heading, and altitude. This work allows real-time monitoring of flying objects in satellite images
