“…Also, developing countries will encounter relatively higher costs for road networks due to climate change impact through 2100, when compared to developed countries. Later, Schweikert et al estimated the impact of climate change on road networks in South Africa (Schweikert et al 2015). This study also came to a common conclusion that proactive adaptation measures can significantly reduce the annual average cost of road networks in South Africa.…”

For the past few decades, researchers all over the world have agreed that the service life of civil infrastructure is significantly affected by climate change. Pavement is one of these significant infrastructures that can be easily affected by climate change. However, it is well known that predicting climate change is highly complex and dynamic. Hence, a review has been done on available climate change models and the uncertainties involved in climate change prediction. This review addresses various important questions such as (1) What is climate change? (2) How to use climate change models? (3) Uncertainties involved in using climate change models. (4) How does climate change impacts the pavement infrastructure? (5) What are the adaptation and mitigation strategies available? and (6) How do economic costs and emissions change due to climate change? This review is useful to understand climate change and its implications on pavement infrastructure.

“…Demonstrated by initiatives such as the Eyre Peninsula Plan in Australia and the Cloudburst Plan in Denmark, comprehensive adaptation plans spanning multiple sectors and considering long-term climate-related hazards are pivotal 127 , 130 . Moreover, the utilization of innovative technologies like robots for railway maintenance in Japan and nature-based drainage systems in Hong Kong bolsters infrastructure resilience and safety 126 , 128 . Collaborative governance, exemplified by the Hurricane Sandy Reconstruction Task Force in the United States 130 , and the Sponge City Program in Hong Kong 129 , underscores the significance of coordinated efforts among government agencies, local communities, and stakeholders.…”

Climate change (CC) will likely significantly impact the world’s infrastructure significantly. Rising temperatures, increased precipitation, and rising sea levels are all likely to stress critical infrastructures (CI). Rising temperatures can lead to infrastructure damage from extreme heat events. This can cause roads and bridges to buckle or crack, leading to costly repairs and potential traffic disruptions. In addition, heat waves can damage vital electrical infrastructure, leading to widespread power outages. In light of this context, this article reports on a study which examined the connections and impacts of CC on infrastructure. The study employed a mixed-method approach, combining bibliometric analysis for the period 1997–2022 with a series of relevant case studies from the five continents to offer insight into the impact of CC on infrastructure. The article fills a research gap in respect of assessments of the extent to which climate change (CC) negative influences the infrastructure, with a special focus on developing countries. It also showcases CI projects and adaptation measures being currently deployed, to address CC. The results show that the current infrastructure is vulnerable to CC. The selected case studies on CI adaptation show that in developing and industrialised countries, there is a perceived need to understand better the connections and potential impacts of CC on critical areas such as transport, settlements, and coastal infrastructure. In order to protect infrastructure from CC impacts, governments need to invest in measures such as flood control, early warning systems, and improved building codes. Additionally, they need to work to reduce greenhouse gas emissions more actively, which are the primary cause of CC.

The Economic Impact of Climate Change on Road Infrastructure in Ghana

This paper estimates the economic impact of climate change on road infrastructure using the stressor-response methodology. Our analysis indicates that it could cumulatively (2020-2100) cost Ghana $473 million to maintain and repair damages caused to existing roads as a result of climate change (no adapt scenario). However, if the country adapts the design and construction of new road infrastructure, expected to occur over the asset's lifespan (adapt scenario), the total cumulative cost could increase to $678.47 million due to the initial costs of adaptation. This investment provides lower costs on a decadal basis later in the infrastructure lifespan. This creates the planning question of whether lower decadal costs in the future are a priority or if minimizing initial costs is a priority. The paper addresses this question through decadal and average annual costs up to the year 2100 for the ten regions, using the potential impacts of 54 distinct potential climate scenarios.
