Rainfall and citizen science

This video is a case study of a project where Practical Action and the Peruvian National Service of Meteorology and Hydrology (SENAMHI) work together with community volunteers using a citizen science approach to monitor precipitation in the Rimac watershed in the outskirts of Lima. The network of volunteers gather data that is used to complement official recording and provide more localised, detailed information which is used to better understand flash flood and landslide risk.

Rainfall and citizen science

There are few historical records of floods & landslides in the Rímac river watershed in terms of hydrometeorological variables with enough spatial and temporal accuracy. Is is a strong limitation to understand the relationship between precipitation and the activation of a ravine. It also limits how people in vulnerable situations can benefit from initiatives related to Early Warning Systems (SAT) at any of its levels: alarm, alert or forecast. On the other hand, people exposed to these risks have wide local knowledge about past events and great willingness to actively participate in disaster risk management.
