Flooding is a global threat causing significant economic and environmental damage, necessitating a policy response and collaborative strategy. This study assessed global research trends and advances in geospatial and meteorological flood risk assessment (G_MFRA), considering the ongoing debate on flood risk management and adaptation strategies. A total of 1872 original articles were downloaded in BibTex format using the Web of Science (WOS) and Scopus databases to retrieve G_MFRA studies published from 1985 to 2023. The annual growth rate of 15.48% implies that the field of G_MFRA has been increasing over time during the study period. The analysis of global trends in flood risk research and practice highlights the key themes, methodologies, and emerging directions. There exists a notable gap in data and methodologies for flood risk assessment studies between developed and developing countries, particularly in Africa and South America, highlighting the urgency of coordinated research efforts and cohesive policy actions. The challenges identified in the body of extant literature include technical expertise, complex communication networks, and resource constraints associated with the application gaps of the study methodologies. This study advocates for a holistic research approach to flood disaster management through ecosystem-based adaptation that underpins the Sustainable Development Goals to develop innovative flood techniques and models with the potential to influence global decision-making in the G_MFRA domain. Addressing these global challenges requires a networked partnership between the research community, institutions, and countries.
洪水是一种全球性威胁，会造成重大的经济和环境破坏，因此需要政策应对和协作战略。本研究评估了地理空间和气象洪水风险评估（G_MFRA）的全球研究趋势和进展，同时考虑了正在进行的关于洪水风险管理和适应战略的辩论。使用科学网（WOS）和Scopus数据库以BibTex格式下载了1872篇原创文章，以检索1985年至2023年发表的G_MFRA研究。15.48%的年增长率表明，在研究期间，G_MFRA领域一直在不断发展。对洪水风险研究与实践的全球趋势分析突出了关键主题、方法和新兴方向。发达国家和发展中国家，特别是非洲和南美洲，在洪水风险评估研究的数据和方法方面存在显著差距，这凸显了协调研究工作和连贯政策行动的紧迫性。现有文献中确定的挑战包括技术专长、复杂的通信网络以及与研究方法应用差距相关的资源限制。本研究倡导通过基于生态系统的适应采取整体研究方法来进行洪水灾害管理，这是可持续发展目标的基础，以开发有潜力影响G_MFRA领域全球决策的创新洪水技术和模型。应对这些全球挑战需要研究界、机构和国家之间建立网络化伙伴关系。
