Combined with expert interpretations, 100,267 Science Citation Index (SCI) journal papers published in Diaster Risk Reduction field in 2022 were retrieved as of December 31, 2022, with 165 countries/regions conducting relevant research. The top 12 countries (>300 papers) in terms of the greatest number of papers published (in descending order) were China, the USA, India, the UK, Italy, Germany, Japan, Australia, Canada, France, Spain, and Iran. China had the highest number of publications worldwide. Beijing Normal University (BNU) had the highest rate of papers cited, followed by the Helmholtz Association of German Research Centers (HGF) and the Swiss Federal Institute of Technology. The Chinese Academy of Sciences (CAS) and the HGF had the highest percentages of highly cited papers.
The papers were mainly distributed across 13 disciplines (each with 300 papers): environmental science, geoscience synthesis, water resources science news, meteorology and atmospheric science, public environment and occupational health, environmental research, green and sustainable technology, geochemistry and geophysics, remote sensing science, environment engineering, geology engineering, imaging science and photography technology, and physical geography. Research on disaster prevention in China are mainly in the following 14 disciplines, with more than 100 papers: environmental science, geoscience synthesis, water resources science, meteorology and atmospheric science, remote sensing science, imaging science and photography technology, environment engineering, geology engineering, geochemistry and geophysics, green and sustainable technology, public environment and occupational health, environmental research, physical geography, and civil engineering. In the field of disaster prevention in China, few studies have been conducted on public environment and occupational health environment.
The five most researched topics are health risks caused by heavy metals, the application of remote sensing technology in earthquake disaster monitoring, disaster management and resilient cities from the perspective of vulnerability, disaster big data under climate change and epidemic situation, and temporal and spatial dynamic change in land use based on geographic information system data.
The appendix presents 90 abstracts from papers with a high citation index, similar to the research direction followed by the Disaster Risk Reduction Knowledge Service sub-platform of the International Knowledge Centre for Engineering Sciences and Technology.
