Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, what steps he is taking to help support citizen science projects on (a) flooding and (b) sewage.

Defra has a strong history of working with citizen scientists, particularly volunteer species recorders who have provided over 70% of Government biodiversity data. The growth of citizen science across cities, the countryside, and rivers, driven by technology and social networks, has resulted in fragmented efforts and resource competition. This complex landscape often sees short-lived and difficult-to-support initiatives.

The Defra Natural Capital & Ecosystem Assessment (NCEA) Programme includes specific research and development to advance Defra and stakeholder engagement with citizen science. Freshwater permeates our landscapes and cities providing a powerful medium through which we can monitor important elements of our natural capital. We have identified 112 existing freshwater citizen science methods. Much of this focuses on rivers, but we are also advancing lake and pond survey capability. Trials have already found 515 new ponds in test cities and online volunteers mapped open water across Northumberland. Freshwater methods will feature within integrated survey designs we are working to trial with stakeholders across various landscapes and cities. A key goal of NCEA research is to explore how best to support environmental citizen science to enhance both national science and public engagement with the environment.

The Environment Agency (EA) has recruited citizen science coordinators that are embedded in front-line teams. This is creating strong relationships with citizen science groups and a large collaborative effort is underway to ensure the data derived from citizen science can be added to the EA’s data.

Citizen science initiatives focused on sewage and wider catchment pressures include Riverfly, The Big River Watch, Great UK WaterBlitz, and SmartRivers. An example relevant to flooding is the Daily Rainfall Observers Network.
