built-up and populated part of the city, is by far the best performing one: more than
2000 citizens would benefit from the enhanced cooling effect produced by the new
green area. The other scenarios are expected to affect from some decades to few
hundreds of people. Overall, the number of people that would benefit from
increased opportunities for nature-based recreation is much higher. Scenarios 07
and 08 produce the highest absolute number of beneficiaries. However, only the
regeneration of brownfields 01, 02 and 03 would serve people that, at present, have
no access to close-to-home nature-based recreational opportunities. The ratio
between total beneficiaries and specific vulnerable groups is not the same across
scenarios, due to the uneven distribution of population groups across the city. For
example, the share of children and teenagers is higher for scenarios 01 and 02
compared to the others, while the share of people aged more than 65 is the highest
for scenario 11.
The information about the number of beneficiaries of the two ES in the different
scenarios was combined through a multi-criteria analysis according to the three
perspectives described in Table 5.1 (Fig. 5.6). When assuming a ‘balanced’ perspective, with the same weight assigned to the two ES and a double weight assigned to
vulnerable compared to non-vulnerable groups, scenario 11 ranks first. The second
perspective, consistent with the objective of improving the cooling effect in areas
with a high share of older population, leads to the same first-ranking scenario.
Although the other positions change between the two perspectives, all scenarios
gain a very low score compared to scenario 11. Under the third perspective, the final
ranking changes significantly and the first positions are occupied by the three scenarios (01, 02 and 03) involving the regeneration of brownfields located in the
northern part of the city, where the population is comparatively younger and existing opportunities for recreation are scarcer.
