TLDR: A comprehensive study analyzed 5,496 academic papers on disaster informatics published between 2020 and 2022 to understand the field’s evolution post-COVID-19. Utilizing advanced AI for topic modeling and summarization, the research identified the most active countries (US, Italy, China, India, UK), institutions, and authors, highlighting their collaboration patterns often influenced by geography or language. The study revealed a significant shift in research priorities towards public health, technological solutions, and environmental impacts, demonstrating how the pandemic broadened the scope of disaster informatics.
The COVID-19 pandemic brought unprecedented global challenges, significantly impacting various aspects of society, including the realm of disaster informatics. A recent comprehensive study delves into the academic literature published between January 2020 and September 2022 to map how disaster informatics research has evolved in the wake of the pandemic. This research provides crucial insights for policymakers, practitioners, and scholars aiming to enhance disaster preparedness and response capabilities in an increasingly complex world.
Disaster informatics is a multidisciplinary field focused on using information technologies to generate, gather, process, store, and disseminate critical data for disaster preparedness, mitigation, response, and recovery efforts. The study highlights that before COVID-19, disaster informatics primarily focused on natural disasters with limited attention to public health. However, the pandemic spurred a dramatic increase in publications, suggesting a shift in research priorities.
Mapping the Research Landscape
The study analyzed a large corpus of 5,496 papers, employing advanced techniques like BERTopic for topic extraction and large language models (LLMs) such as Llama 2 and GPT-3.5-turbo for topic summarization. This robust methodology allowed researchers to identify key contributors, collaboration networks, and emerging research themes.
The findings reveal that countries most impacted by the COVID-19 pandemic were also the most active in disaster informatics research. The United States, Italy, China, India, and the United Kingdom led in publications and international collaborations. Collaboration patterns often followed geographical proximity or shared language, forming distinct groups among English-speaking, European, Asian, and Latin American countries. This extensive global collaboration underscores the recognition of disaster and crisis-related challenges as inherently global.
Leading institutions included King Saud University, the University of California, the University of Toronto, the University of Porto, and Sapienza University of Rome. Similar to countries, institutional collaborations were influenced by geographical proximity and common language, leading to the formation of research groups within the same country or region. Among authors, Mario Coccia, Charis Galanakis, and Christian Reuter were identified as the most prolific. A notable pattern among active authors was the tendency to form close partnerships with one or two key collaborators, alongside broader networks of occasional collaborations.
Emerging Research Priorities
The study identified 12 significant topics that emerged in disaster informatics research post-COVID-19. These topics reflect a broadened scope, integrating public health, technological solutions, and environmental impacts into the field. Key areas of focus included:
- The impact of COVID-19 on international trade.
- Burnout among healthcare professionals during the pandemic.
- The use of medical technology and additive manufacturing to address supply shortages.
- Waste management and the environmental impacts of COVID-19.
- Community pharmacy practice during the pandemic.
- Genomics and variants of SARS-CoV-2.
- The role of nutrition in the immune system during COVID-19.
- The pandemic’s impact on dental education and practice.
- The impact of COVID-19 on pregnant women and maternal health.
- Shifts in consumer behavior and trust during the pandemic.
- Advancements in virus inactivation and detection techniques.
- The role of technology in managing the COVID-19 pandemic.
These topics demonstrate a clear evolution of disaster informatics from a narrow focus on natural disasters to a more holistic approach addressing a wide range of pandemic-related challenges. For instance, the U.S. showed strong interest in topics related to the pandemic’s impact on dental education, international trade, and the use of technology, while India prioritized research on nutrition, virus inactivation, and waste management. Authors often specialized in one or two topics, whereas institutions displayed more diverse research interests across several areas.
