Editorial: Identifying hotspots of hydro-hazards under global change

Hydrological hazards (“hydro-hazards”) can be defined as extreme events related to phenomena phenomena of water distribution in the context of floods and droughts. Flood hazards are of water overflowing due to one or combined sources (e.g., surface, surface, sub-surface, coastal, fluvial); on the contrary, drought hazards derive from a shortage of precipitations, river flows or sub/surface water over prolonged periods (Van Loon et al., 2016). Considering the effect of climate change on global and regional weather patterns, in the future flood and drought hazards are expected to alter their nature and location (Visser-Quinn et al., 2019). Ongoing research is applying climate projections to hazard and impact assessment to determine such future trends worldwide. Projections uncertainties, modeling approaches and relative implications are now becoming measurable, due to increasing computational capability and advanced data analytics (Jafarzadegan et al., 2021; Songchon et al., 2021). However, despite such progress in regional understanding, a complete and coherent picture is still missing at global level.
