Residents of a Nairobi slum are on a mission to reducing the damage from flooding in their area.

Volunteers work together to clear debris and waste that is blocking the waterways and drainage at an informal settlement.

Armed with shovels, brushes and rakes, the volunteers are working with Weather Mtaani – a group set up to help improve life for the people living here.

A lack of proper working drainage systems means flooding is likely when it rains, due to it being clogged with rubbish such as plastics, clothing and sludge.

The Kenya Meteorological Department (KMD) has been training young people from informal settlements to interpret weather forecasts.
