**3. Disruptive innovation with citizen science (CS)**

## **3.1 The challenge being addressed**

The United Nations Sustainable Development Goals (SDGs), announced in September 2015, has a vision of achieving a higher level of human health and wellbeing worldwide by the year 2030. The SDG targets specific to water and sanitation call for more detailed monitoring and response to understand the coverage and quality of safely managed sources. This provides challenges to monitoring but also opportunities to use innovative and disruptive approaches to gathering water quality data.

In order to fill gaps in data for water bodies, it is necessary to find ways of gathering information at higher spatial and temporal frequency than is feasible with current monitoring programmes.
