GREEN-POLIS: Nature-Based Solutions for Urban Heat and Pollution
The project investigates Nature-Based Solutions to mitigate urban heat and pollution islands, using multiscale analysis on Bologna through experiments, simulations, and measurement campaigns.
Abstract
GREEN-POLIS aims at studying the efficacy of selected Nature-Based Solutions (NBSs) in mitigating the negative effects caused bythe Urban Heat Island (UHI) and the Urban Pollution Island (UPI). The investigation will be conducted in a multiscale prospective,ranging from the street and building scale to the city neighbourhood.The proposal aims at providing evidence-based analysis, grounded on a rigorous scientific approach, to build a robust and systemicknowledge of the most effective urban NBSs, their potential benefits as well as the possible side effects. Such a challenge isaddressed by enforcing a systematic investigation that starts with the detailed analysis of microscale effects of NBSs on the in-cityventilation, temperature, pollutant dispersion in prototypal urban geometries, through the use of laboratory experiments andhigh-resolved numerical simulations. Subsequently, the knowledge gained is applied for testing and improving urban numericalparameterizations for mesoscale meteorological models, allowing the analysis of an extensive implementation of NBSs consideringan urban area. The city of Bologna located in the Po Valley, a recognized hotspot of climate change and air pollution, is taken as apractical case study that will be investigated experimentally through an extensive measuring campaign based on meteorological andlow-cost sensors, and numerically through mesoscale simulations that analyse selected scenarios where different urban NBSs arevirtually implemented. In such a way, GREEN-POLIS will perform a multiscale investigation ranging from the street to the city scale,which is based on the knowledge gained in simplified configurations and progresses towards application in the real field.
