mentioned evenly in the three components.
2.3.2 Quality of ES Inclusion in Urban Plans
The overall quality of ES inclusion (Fig. 2.3) is generally low, with only two plans
in the sample reaching the score of 1.5 in the 0–3 range obtained by summing the
normalized scores in the three components. The actions component receives the
highest average normalized score (0.65), while normalized scores for the information base and the vision and objectives components are lower than 0.5 in all plans.
When looking at the distribution of quality scores for the different urban ES in the
different plan components, it emerges that the most common quality score in the
information base component is equal to 1. However, the same pattern discussed for
the breadth indicator emerge with respect to the different ES. Although the overall
performance is quite poor, five ES (water flow regulation and runoff mitigation,
recreation, air purification, noise reduction, and urban temperature regulation) are
addressed in this component more often and with a higher quality compared to the
others. Water flow regulation and run-off mitigation and recreation are the only ones
for which some of the plans were given the highest scores. However, only analyses
