Infrastructure are resilient when they are able to recover from disasters brought by natural hazards (e.g., earthquakes, tsunamis, hurricanes, cyclones, tornados, floodings, and droughts) and anthropogenic hazards (e.g., human errors, malevolent attacks). Sustainability and resilience depend on each other but they also may call for conflicting actions. Because of this, it is essential to find the right balance with tradeoffs. Sustainability calls for sensible and parsimonious use of limited resources, and a minimal impact on the environment. At the same time, long-term sustainability depends on infrastructure resilience where infrastructure built today can serve communities for many years, weathering possible disruptions without the need for major reconstruction. However, infrastructure resilience often calls for significant use of scarce resources with significant environmental impact, which in turn hurts sustainability. A crucial challenge that will likely be the focus of significant research in the coming years is to find solutions that are both sustainable and resilient. Resilience depends on both the performance of the built and modified natural environment and on the contextual characteristics of social, economic, and political institutions. Both sustainability and resiliency are impacted by the external environment, and today’s external environment is changing in ways that increase the uncertainty associated with the performance of infrastructure. Climate change, dynamic geopolitical situations and policies, fluctuating economic conditions, changing human behaviors, urban growth, and other factors lead to dynamic changes, new needs, and increasing uncertainty. Societies must learn how to deal with these changes and growing uncertainty so that societies can achieve longterm infrastructure sustainability and resilience. Although sustainability and resilience are often associated with the built environment, infrastructure can be both physical and non-physical systems. Designers, engineers, scientists, economists, and policyand decision-makers must learn how to address and deal with these changes, new needs, and growing uncertainties. Historical processes have been static. Dynamic processes are required. Understanding the causes and impacts of disasters through holistic, systemic, and multi-disciplinary analysis will be essential to deal with these changing external environments. Robust decisionmaking and dynamic planning processes are necessary to achieve reliable and sustainable services under the stresses from climate change, disasters, and other stressors. Adaptive and integrated disaster resilience, and thus sustainability, is dependent on nations and communities designing and building resilience in a systematic and integrated manner that can adapt to changing environments.

In urban areas where most of the population lives, floods occur due to sudden, short-term but heavy rains caused by climate change. Infrastructure deficiencies have also caused considerable loss of life and property. I have discussed policies and practices of public administration formed by central government and local administrations focusing on climate change resilience and adaptation. I have also evaluated policy areas that need further development. This study can contribute to finding solutions to problems faced by cities in Turkey and other nearby countries. Findings show that participatory processes involving scientific and local knowledge can play a key role. Green and blue infrastructure with grey infrastructure and associated engineering solutions should also be used. Legislation should be updated to expand the use of nature-based solutions and green infrastructure, which should form a key focus of urban policy development.","PeriodicalId":45395,"journal":{"name":"Sustainable and Resilient Infrastructure","volume":null,"pages":null},"PeriodicalIF":5.9,"publicationDate":"2022-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47374854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Corridor is defined as a set of bridges that works jointly to ensure connectivity and traffic flow between different areas of a region. To detect Corridors, a Markov Clustering Algorithm is proposed. Using the San Francisco Bay Area road network as a testbed, this clustering technique selects sets of bridges that correspond to main traffic arteries such as highways and high-capacity road segments. After Corridors have been detected, a two-stage stochastic optimization is implemented to detect which bridges should be retrofitted to ensure an acceptable network performance. This optimization couples retrofitting actions in a Corridor with the repair actions to damaged bridges after an earthquake. The Corridors-Supported Optimization decreases road network disruption more than other approaches based on ranking bridges according to their traffic capacity or location in the network.","PeriodicalId":45395,"journal":{"name":"Sustainable and Resilient Infrastructure","volume":null,"pages":null},"PeriodicalIF":5.9,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45061148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bedrock-level peak ground acceleration varied from 0.14 to 0.69g for the return period of 475 years. Using PCA, the social vulnerability index (SVI) was generated considering district-level socioeconomic indicators. Built environment quality, illiteracy, access to amenities, dependent population, and employment opportunities contributed to high SVI. Most vulnerable districts were concentrated in the Brahmaputra floodplains, Tripura fold belt, and Imphal valley. At the regional level, significant parts of Assam, Meghalaya, Arunachal Pradesh, and Tripura lie in moderate to very high-risk zones. At the sub-regional level, Nagaland accounts for the highest proportion of areas in high to very high-risk zones. The findings will aid site-specific resilient infrastructure design, disaster risk reduction, and effective resource allocation for the risk-prone areas.","PeriodicalId":45395,"journal":{"name":"Sustainable and Resilient Infrastructure","volume":null,"pages":null},"PeriodicalIF":5.9,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47467945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A coding-based weighted model is used to analyse 8 Case Studies. Key findings are: (a) Strengthening of communities and local institutions through capacity building (communications APs) from inception is prerequisite for combined resilience. This is significant even in absence of other AP factors including evidence-based policy, governance, innovation; (b) Capacity building should focus on designing local resource-based approaches [LRBA], nature-based solutions [NBS], and community indigenous knowledge thereby improving other AP factors; (c) Policy formulation on asset management and quality assurance should be pre-requisite for mobilisation and funds allocation to strengthen community-led APs for combined resilience.","PeriodicalId":45395,"journal":{"name":"Sustainable and Resilient Infrastructure","volume":null,"pages":null},"PeriodicalIF":5.9,"publicationDate":"2022-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47563413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adaptive pathways, given its inherent consideration of uncertainty and an embedded feedback mechanism, becomes a necessary conceptual underpinning to deliver on the resilient infrastructure challenge. We argue that knowledge and iterative learning are key components that enable the flexibility of adaptive pathways. Higher education (HE) plays a critical role in influencing knowledge that is adaptive and dynamic to respond to this challenge. This study adopts a qualitative approach with a case study design to identify gaps in how urban resilient infrastructure is conceptualised and taught in HE institutions. .

Traditional load factors, safety factors, and design standards appear misaligned with current and anticipated future conditions. Thus, adapting infrastructure for a changing climate will likely necessitate balancing trade-offs between new and old design paradigms. This literature review summarizes advances in the implementation and research of resilient infrastructure within the context of climate change. We identified three categories of adaptation strategies: (1) assessments and frameworks to incorporate climate data and risks into infrastructure design and planning, (2) modelling of decision making under uncertainty and policy analysis, and (3) examples of best practices, case studies, and workarounds to enhance resilience. This work highlights advances in infrastructure decision making under uncertainty and ways to instill resilience into infrastructure systems.

The resilience capability in energy infrastructures can be realized through effective planning decisions and maintenance strategies by implementing the condition-based monitoring (CBM) approach. CBM minimizes the unplanned downtime of a system by monitoring the system's health status in real-time and predicting upcoming failures. Thus, the planned maintenance can be performed before failures occur. With advancements in data analytics, conventional CBM methods have been enhanced with modern artificial intelligence algorithms to improve the prediction accuracy. This paper comprehensively evaluates the importance of CBM as a robust strategy to enhance energy infrastructure resilience. The vulnerabilities of energy infrastructure and current advancements in data-driven CBM methods are detailed. Furthermore, this survey equip energy infrastructure stakeholders and practitioners with CBM knowledge in managing unforeseen disaster risks, such as power failures due to adverse weather conditions.","PeriodicalId":45395,"journal":{"name":"Sustainable and Resilient Infrastructure","volume":null,"pages":null},"PeriodicalIF":5.9,"publicationDate":"2022-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47588968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
