Maximising the Potential of Citizen Scientists

About the film

Monitoring the health of our rivers is crucial for improving water quality, but local authorities and the Environment Agency often lack the resources for continuous, long-term data collection. This is where citizen scientists play an essential role. Local volunteers, who have a deeper understanding of their rivers and are a constant presence, gather a wide range of data that wouldn’t be possible otherwise. This involvement democratises river monitoring and fosters a stronger emotional connection between communities and river improvement projects.

The data collected by citizen scientists is vital for water companies and local authorities to implement effective water quality measures. A key example is the Chiltern AONB citizen science network, which collaborates with Thames Water, the Environment Agency, and local authorities. Through a series of scientific projects, they monitor the three pillars of river health: water quantity, water quality, and habitat health. Their efforts have revolutionised the way under-resourced utilities manage and interact with freshwater ecosystems, proving the power of citizen engagement in driving meaningful change.
