Flash floods are among the world’s deadliest natural disasters with more than 5 000 lives lost annually. Their social, economic and environmental impacts are significant. Accounting for approximately 85% of flooding cases, flash floods also have the highest mortality rate among different classes of flooding, including riverine and coastal. Flash floods differ from river floods in their short time scales and occurrence on small spatial scales, which makes flash flood forecasting a different challenge from large-river flood forecasting.

Water and Climate Coalition leaders have endorsed an ambitious Action Plan to achieve a more integrated global water and climate agenda in the face of growing global threats to water and from water-related hazards. It aims to usher in an era of more sustainable water management and related climate change action instead of the existing siloed approaches.
Climate change is exacerbating both water scarcity and water-related hazards, as rising temperatures disrupt precipitation patterns and the entire water cycle. Currently, 3.6 billion people face inadequate access to water at least a month per year and this is expected to increase to more than 5 billion by 2050.
A new Water and Climate Coalition has been launched to achieve more effective integrated policy-making in an era when climate change, environmental degradation and population growth has exacerbated water-related hazards and scarcity
