Flash floods are a growing threat in some of the world’s driest regions. Here's why these areas are so high-risk
). So far, 28 warning systems are up and running, with another 39 in development. Eight of the operational systems are in drylands, together with ten of those still in development. More dryland nations need to be engaged.
Researchers need to examine the trade-offs. For example, protection measures might encourage more development in flood-prone areas — as was the case in Columbia, South Carolina, which experienced extensive damage from a flash flood in 2015. And dams and levees built to hold back small floods could offer a false sense of security from rare, extreme inundations, including one that flooded the Atacama region in South America in 2015.
Researchers should aim to quantify how effective natural features are at storing and conveying water, and how resilient they are to extreme floods. Local differences in soil and vegetation conditions must be considered. More needs to be known about how the systems degrade and how to maintain them.
Managed resettlement is more equitable and efficient than leaving people to fend for themselves. Cross-disciplinary research in social science, geography, engineering and psychology is required to investigate the best way to manage retreat, by providing essential services and assistance while avoiding food insecurity and lost livelihoods.Risk-transfer schemes — such as flood insurance, catastrophe bonds and solidarity funds — should be developed for drylands.
