A systematic review published in August in the journal Frontiers in Public Health finds that citizen science can help monitor many health and well‑being targets in the UN Sustainable Development Goals and the WHO Triple Billion Targets. The authors are from the International Institute for Applied Systems Analysis and WHO.
The review says citizen science can add to traditional data for many health indicators and has most potential in environment, health and well‑being. Examples include people sharing observations of plants and animals, collecting plastic from rivers, and measuring water or air quality.
The study notes gaps in official data. It gives a practical case: Ghana used citizen science data on marine plastic litter in its SDG reporting. The authors also mention challenges such as recruiting volunteers and data quality.
