Once infamous for its dry weather, the desert state now receives erratic rainfall, which has even led to flooding a few times.
In 2017, the state suffered heavy losses due to floods after heavy rains, as the people of Rajasthan know how to deal with droughts but are unprepared for flooding. Even the state’s disaster management plan did not include floods.
Incidences of flooding in the state have only increased since then. There was excess rainfall of 141 per cent in the monsoon of 2019. In the monsoon season of 2021, Rajasthan received 117 per cent excess rainfall. September 2021 witnessed 176 per cent excess rainfall than average.
