The Coastal Niño event of 2017 led to extreme rainfall in Peru, which was made more likely by at least 1.5 times as compared to pre- industrial times due to anthropogenic climate change and Coastal Niño  and comparable to the El Niño events of 1982-1983 and 1997-1998 . This event showed evidence of larger anomalies in flood exposure  and sediment transport . In Peru, this Niño event led to USD 6 to 9 billion of monetary losses, more than a million inhabitants were affected, 6614 km of roads were damaged, 326 bridges were destroyed, 41,632 homes were damaged or became uninhabitable and 2150 schools and 726 health posts were damaged , leaving half of the country in a state of emergency . Furthermore, institutional and systemic sociocultural and political conditions at multiple levels significantly worsened disaster risk management which hampered response and recovery . Citizens and zero-order responders proved to be more effective and quicker than national disaster risk management response .
