5.5 Lesson Learned and Conclusions
The case study showed a possible use of ES knowledge to support urban planning
in the stage of the planning process when decisions amongst alternative scenarios
are to be made. Specifically, it addressed the issue of brownfield regeneration in the
city of Trento, where the presence of thirteen sites that could be converted to new
public green areas determines the need for a rational approach to select and prioritise interventions. The presence of brownfields is a key issue for today’s cities, with
strong economic and social implications (Nassauer and Raskin 2014). Recent studies have highlighted how brownfields can be turned into sources of ES for the urban
population (McPhearson et al. 2013; Collier 2014; Mathey et al. 2015; Geneletti
et  al. 2016; Beames et  al. 2018), thus contributing to a more sustainable urban
development (European Commission 2016).
