The sustainable development of the cities aims to increase the green areas since the vegetation addresses diverse urban challenges such as air quality, climate, human health, etc.. Therefore, EU LIFE project VEG GAP is developing new methodologies and tools for analyzing the air quality of our cities and, thus, supporting the air quality management and urban planning . The information platform developed in the project provides useful information on linkages between vegetation, temperature, and air pollution and can be used in the development of effective control strategies to maintain and improve air quality in European cities. The project partners will show the new tools developed and the current local understanding on vegetation effects for the pilot cities: Bologna, Madrid and Milano. In the second Workshop organised in Bologna by the EU LIFE VEG GAP project, after receiving information about the project and its platform, the audience will be invited to interact with the speakers and provide input for the improvement of the platform.
