ABSTRACTClimate change is already being experienced in the Arctic with implications for ecosystems and the communities that depend on them. This paper argues that an assessment of community vulnerability to climate change requires knowledge of past experience with climate conditions, responses to climatic variations, future climate change projections, and non-climate factors that influence people's susceptibility and adaptive capacity. The paper documents and describes exposure sensitivities to climate change experienced in the community of Ulukhaktok, Northwest Territories and the adaptive strategies employed. It is based on collaborative research involving semi-structured interviews, secondary sources of information, and participant observations. In the context of subsistence hunting, changes in temperature, seasonal patterns (for example timing and nature of the spring melt), sea ice and wind dynamics, and weather variability have affected the health and availability of some species of wildlife important for subsistence and have exacerbated risks associated with hunting and travel. Inuit in Ulukhaktok are coping with these changes by taking extra precautions when travelling, shifting modes of transportation, travel routes and hunting areas to deal with changing trail conditions, switching species harvested, and supplementing their diet with store bought foods. Limited access to capital resources, changing levels of traditional knowledge and land skills, and substance abuse were identified as key constraints to adaptation. The research demonstrates the need to consider the perspectives and experiences of local people for climate change research to have practical relevance to Arctic communities such as for the development and promotion of adaptive strategies.

Many of the world’s most disaster-prone cities are also the most difficult to model and plan. Their high vulnerability to natural hazards is often defined by low levels of economic resources, data scarcity, and limited professional expertise. As the frequency and severity of natural disasters threaten to increase with climate change, and as cities sprawl and densify in hazardous areas, better decision-making tools are needed to mitigate the effects of near- and long-term extreme events. We use mostly public data from landslide and flooding events in 2017 in Freetown, Sierra Leone to simulate the events’ impact on transportation infrastructure and continue to simulate alternative high-risk disasters. From this, we propose a replicable framework that combines natural hazard estimates with road network vulnerability analysis for data-scarce environments. Freetown’s most central road intersections and transects are identified, particularly those that are both prone to serviceability loss due to natural hazard and whose disruption would cause the most severe immediate consequences on the entire road supply in terms of connectivity. Variations in possible road use are also tested in areas with potential road improvements, pointing to opportunities to harden infrastructure or reinforce redundancy in strategic transects of the road network. This method furthers network science’s contributions to transportation resilience under hydrometeorological hazard and climate change threats with the goal of informing investments and improving decision-making on transportation infrastructure in data-scarce environments.

<p>The Beaufort Delta region in Northwest Territories, Canada is one of the most rapidly warming areas on Earth. Permafrost thaw and climate change are major stressors on northern infrastructure, particularly in this region which hosts the highest density of Arctic communities and the longest road network constructed on ice-rich permafrost in Canada. The Dempster and Inuvik to Tuktoyaktuk Highways (ITH) comprise a 400-km corridor connecting the region with southern Canada. The corridor delivers a unique opportunity to develop a societally-relevant, northern-driven permafrost research network to encourage collaboration, and support pure and applied studies that engage stakeholders, encourage community participation, and acknowledge northern interests. Successful implementation requires leadership and institutional support from the Government of the Northwest Territories (GNWT) and Inuvialuit and Gwich’in Boards and landowners, and coordination between research organizations including NWT Geological Survey, Aurora Research Institute, Geological Survey of Canada, and universities to define key research priorities, human and financial resources to undertake studies, and protocols to manage data collection and reporting.</p><p>In 2017, a state of the art ground temperature monitoring network was established along the Dempster-ITH corridor by the GNWT in collaboration with Federal and Academic partners. This network in combination with the maintenance of the Dempster Highway and recent design and construction of the ITH, has created a national legacy of permafrost geotechnical, terrain and geohazard information in this region. The objectives of this program are to integrate old and new data to synthesize physiographic, hydrological, thermal, and geotechnical conditions along the corridor, and to develop applied permafrost research projects that support planning and maintenance of this critical northern infrastructure. In this presentation, we highlight: 1) a collaborative research framework that builds northern capacity and involves northerners in the generation of knowledge and its application to increase community based permafrost monitoring; 2) summaries of existing infrastructure datasets and their foundation for research; and 3) new projects that address emerging climate-driven infrastructure stressors. As the effects of climate change on permafrost environments, infrastructure and communities continue to increase, the need for northern scientific capacity and applied research to support informed decision-making, climate change adaptation and risk management will become increasingly critical. The development of resilient researcher-stakeholder-community relationships is also necessary for the scientific and research initiatives to reach their potential.</p><p> </p>

Loss And Damage

In Southeast Asia, climate change will potentially have negative consequences for urban transportation infrastructure (UTI). It is necessary to improve the understanding of climate change-associated loss and damage in relation to UTI to ensure the sustainability of existing transportation assets and for prioritizing future investments. However, there is currently limited knowledge on how to practically assess loss and damage for UTI in the context of climate change and then to incorporate appropriate adaptation measures and strategies to future-proof transportation planning. This study presents the results and experiences from assessing climate change-related loss and damage to UTI in six cities of Cambodia, Thailand and Vietnam. One pilot city from each country was selected for assessment by applying NK-GIAS software to determine loss and damage for urban roads. It was found that the six selected cities were highly vulnerable to climate change given their location and exposure to sea-level rise, storm surge, flooding, and salinity intrusion. Through analyses conducted using NK-GIAS software, economic losses for different flood scenarios were determined. The linkage between flooding and road damage was demonstrated, with maximum damage estimations under the most extreme flooding scenario of approximately 20 million USD for Hoi An, 3 million USD for Kampot and 21 million USD for Samut Sakhon, corresponding to water levels of 3.4 m, 4.0 m and 2.7 m respectively. Damage to the road network was identified as a key impact related to climate change. Further research is recommended to develop appropriate damage curves through laboratory analysis, addressing both flood depth and duration, to strengthen the NK-GIAS analyses undertaken in this study.

<p>Climate change is already impacting the performance and integrity of transportation infrastructure around the world and is anticipated to have serious ramifications for infrastructure safety, environmental sustainability, economic vitality, mobility and system reliability. These impacts will disproportionately affect vulnerable populations and urban locations as well as compromising the resilience of the larger interconnected physical, cyber, and social infrastructure networks. For this reason, increasing the resilience of transportation infrastructure to current and future weather and climate extremes is a global priority.</p><p>The complexity of this challenge requires a convergence approach to foster collaboration and innovation among technically and socially diverse researchers and practitioners. The multi-institutional <strong>ICNet Global</strong> Network of Networks unites domestic and international research and practice networks to facilitate integrated engineering, climate science, and policy research to advance the development of resilient transportation infrastructure and systems. ICNet Globalcollaborators represent networks based in Korea, Europe, United Kingdom, and the United States and link researchers at the forefront of scientific, engineering, and policy research frontiers, drawing expertise from many disciplines and nations to share and enhance best practices for transportation resilience.</p><p><strong>ICNet Global’s</strong> long-term mission is to prepare the world’s existing and future transportation infrastructure for a changing climate. To that end, we are working to: (1) build a network of existing research networks who are tackling the challenges climate change poses to transportation infrastructure; (2) establish a common base-level knowledge, capacity, and vision to support the convergence of novel and diverse ideas, approaches, and technologies for creating climate resilient transportation infrastructure; and (3) grow the next generation of critical and diverse thinkers with the expertise to address and solve climate-related infrastructure challenges. Although just one year into our work, and dispite challenges represented by COVID-19, we have surveyed over 100 potential members worldwide to learn about fields of interest and held five productive virtual workshops to discuss current research, how to encorporate climate change information into engineering education, and how practitioners are currently including climate information into planning and design. In this presentation we highlight our goals and recent accomplishments while laying out future plans and inviting interested researchers and practitioners to join us.</p>
