Item Cork City, Ireland: A blueprint for transformation in second-tier urban centres(Elsevier Ltd., 2024-07-25) Ryan, Marie; Noonan, Lisa; Doyle, Eleanor; Linehan, DenisThis paper analyses Cork's trajectory towards a sustainable, innovative, and globally connected urban centre. On Ireland's south coast, Cork serves as an exemplar of how second-tier cities can undergo transformation and structural change, emerging as an exemplar of economic success. The paper explores the synergies between policymaking, labour markets, and transportation improvements, specifically in the pharmaceutical and IT sectors, noting their clustering and success in international markets. It explores challenges and opportunities presented by demographic shifts alongside an analysis of Cork's transport system, its port capabilities, and connectivity. The paper links to the UN SDGs and suggests strategies to promote sustainable growth and boost innovation. These enhance Cork's technological capacities, educational attainment, sustainable urban planning, and transport systems. It offers insights into urban development, focusing on place-based, future-oriented solutions and strategic directions for Cork. This study extends beyond Cork, offering a roadmap for other second-tier cities grappling with similar challenges and opportunities. It emphasises the need for comprehensive unified approaches to urban planning, aligning with global sustainability objectives, innovative standards, and best practices in city management. Cork not only pioneers its path towards resilience and innovation but also serves as a model for global second-tier cities, showcasing the growth and transformation potential of urban centres.Item Application of repeat-pass TerraSAR-X Staring Spotlight interferometric coherence to monitor pasture biophysical parameters: Limitations and sensitivity analysis(Institute of Electrical and Electronics Engineers (IEEE), 2017-04-03) Ali, Iftikhar; Barrett, Brian; Cawkwell, Fiona; Green, Stuart; Dwyer, Edward; Neumann, MaximThis paper describes the potential and limitations of repeat-pass synthetic aperture radar interferometry (InSAR) to retrieve the biophysical parameters of intensively managed pastures. We used a time series of eight acquisitions from the TerraSAR-X Staring Spotlight (TSX-ST) mode. The ST mode is different from conventional Strip map mode; therefore, we adjusted the Doppler phase correction for interferometric processing. We analyzed the three interferometric pairs with an 11-day temporal baseline, and among these three pairs found only one gives a high coherence. The results show that the high coherence in different paddocks is due to the cutting of the grass in the month of June, however the temporal decorrelation in other paddocks is mainly due to the grass growth and high sensitivity of the X-band SAR signals to the vegetation cover. The InSAR coherence (over coherent paddocks) shows a good correlation with SAR backscatter (R 2 dB = 0.65, p <; 0.05) and grassland biophysical parameters (R 2 Height = 0.55, p <; 0.05, R 2 Biom ass = 0.75, p <; 0.05). It is thus possible to detect different management practices (e.g., grazing, mowing/cutting) using SAR backscatter (dB) and coherence information from high spatial short baseline X-band imagery; however, the rate of decorrelation over vegetated areas is high. Initial findings from the June pair show the possibility of change detection due to the grass growth, grazing, and mowing events by using InSAR coherence information. However, it is not possible to automatically categorize different paddocks undergoing these changes based only on the SAR backscatter and coherence values, due to the ambiguity caused by tall grass flattened by the wind.Item Quantifying the distribution and potential biotic interactions between deer and flora using species distribution modelling(Taylor & Francis, 2023-07-03) O’Mahony, J.; Vanmechelen, A.; Holloway, PaulInvasive species are ranked as one of the leading drivers of global biodiversity loss. To mitigate their impact, we must understand the future risks caused by invasive species, particularly to flora of conservation concern. Here we used species distribution modelling (SDM) to project the current and future (RCP45 and RCP85 2050) distributions of four deer species and 13 plant species of conservation concern for the island of Ireland, quantifying changes in distributions and overlap. Large areas of suitable habitat for the deer species were predicted with high accuracy across all counties, with future climate scenarios identifying an expansion in sika deer distributions and a decrease in muntjac and fallow deer distributions. Red deer declined under the moderate climate change scenario but increased under the worst-case projection. Future projections predicted the (local) extinction of six (out of 13) endangered and vulnerable plant species. An expansion in distributions was observed for four plant species; however, these areas had large overlap with the future predictions of deer, placing further pressures on these plant species. These findings suggest that targeted conservation and management measures are required to alleviate the pressures on ‘at-risk’ plant species due to grazing from native and non-native deer.Item Overcoming "crisis": Mobility capabilities and "stretching" a migrant identity among young Irish in London and return migrants(John Wiley & Sons, Inc., 2019-03-25) Lulle, Aija; Coakley, Liam; MacÉinrí, PiarasWe bring into dialogue the migrant identities of young Irish immigrants in the UK and young returnees in Ireland. We draw on 38 in-depth interviews (20 in the UK and 18 in Ireland), aged 20–37 at the time of interview, carried out in 2015–16. We argue that “stretching” identities – critical and reflective capabilities to interpret long histories of emigration and the neglected economic dimension – need to be incorporated into conceptualizing “crisis” migrants. Participants draw on networks globally, they choose migration as a temporary “stop-over” abroad, but they also rework historical Irish migrant identities in a novel way. Becoming an Irish migrant or a returnee today is enacted as a historically grounded capability of mobility. However, structural economic constraints in the Irish labour market need to be seriously considered in understanding return aspirations and realities. These findings generate relevant policy ideas in terms of relations between “crisis” migrants and the state.Item Environmental forcing by submarine canyons: evidence between two closely situated cold-water coral mounds (Porcupine Bank Canyon and Western Porcupine Bank, NE Atlantic)(Elsevier, 2022-12) O'Reilly, Luke; Fentimen, Robin; Butschek, Felix; Titschack, Jürgen; Lim, Aaron; Moore, Niamh; O'Connor, Owen J.; Appah, John; Harris, Kim; Vennemann, Torsten; Wheeler, Andrew J.; Science Foundation Ireland; Geological Survey of Ireland; Marine Institute; Horizon 2020; Exzellenzcluster Ozean der Zukunft; Deutsche ForschungsgemeinschaftWithin the Porcupine Bank Canyon (NE Atlantic), cold-water coral (CWC) mounds are mostly found clustered along the canyon lip, with individual disconnected mounds occurring nearby on the western Porcupine Bank. Remotely operated vehicle-mounted vibrocoring was utilized to acquire cores from both of these sites. This study is the first to employ this novel method when aiming to precisely sample two closely situated areas. Radiometric ages constrain the records from the early to mid-Holocene (9.1 to 5.6 ka BP). The cores were then subjected to 3D segmented computer tomography to capture mound formation stages. The cores were then further examined using stable isotopes and benthic foraminiferal assemblages, to constrain the paleoenvironmental variation that influenced CWC mound formation of each site. In total, mound aggradation rate in the Porcupine Bank Canyon and western Porcupine Bank was comparable to other Holocene CWC mounds situated off western Ireland. Results derived from multiproxy analysis, show that regional climatic shifts define the environmental conditions that allow positive coral mound formation. In addition, the aggradation rate of coral mounds is higher adjacent to the Porcupine Bank Canyon than on the western Porcupine Bank. Benthic foraminifera assemblages and planktic foraminiferal d13C reveal that higher quality organic matter is more readily available closer to the canyon lip. As such, we hypothesize that coral mound formation in the region is likely controlled by an interplay between enhanced shelf currents and the existence of the Eastern North Atlantic Water-Mediterranean Outflow Water-Transition Zone. The geomorphology of the canyon promotes upwelling of these water masses that are enriched in particles, including food and sediment supply. The higher availability of these particles support the development and succession of ecological hotspots along the canyon lip and adjacent areas of the seafloor. These observations provide a glimpse into the role that submarine canyons play in influencing macro and micro benthic fauna distributions and highlights the importance of their conservation.
