Knowledge map and hotspot analysis in climate resilience infrastructure (CRI) from 1997 to 2022 through scientometric...

The global consensus is to reduce greenhouse gas emissions and actively respond to climate change (CC). Global warming has irreversibly altered the Earth's ecosystems. Unpredictable extreme weather events caused by CC are posing new risks to urban infrastructure. Infrastructure is one of the primary guarantees to maintain the stable operation of the city. Therefore, it is imperative to strengthen the climate resilience of infrastructure to avoid the loss of life and property caused by climate risks. This paper uses CiteSpace to analyze data in the field of climate resilience infrastructure (CRI) over the past 25 years. We find that global CRI research has transitioned through three stages. According to the geographic spatial distribution map drawn by ArcGIS, it can be found that developed countries account for a relatively large number of documents. The research institution is dominated by institutions of higher learning, with limited cooperation between institutions and loose organizational collaboration. CRI is composed of multi-disciplinary collaborative development, from a single discipline of environmental ecology or water resources to a research field integrating engineering, meteorology, sustainability, and energy. Urban resilience and Nature-based solutions are research hotspots. Small Island Developing States are major objects in the future. The research emphasis has shifted from addressing the multiple problems caused by CC to increasing the climate resilience of infrastructure to enhance the resistance of urban systems. Renewable energy and climate models are applied to infrastructure construction. In general, CRI is a effective measure that can help reduce environmental pollution, carbon emissions, and global climate regulation. In addition, we suggest taking cities as pilot projects in the future, increasing CRI projects and providing policy guidance for urban planning and construction.
