Fig. 5: Least complete UMF indicators by domain and their citizen science potential.

For each domain in the UMF, the five indicators with the lowest level of completeness across all cities are shown in ranked order, shaded according to whether citizen science is already contributing to the indicator (green), whether it could potentially contribute (yellow) or whether there is no alignment between the indicator and citizen science (gray). To the right of each indicator is the scale at which the indicator is reported, i.e., the distribution by national, subnational and city levels.
