MAtchUP looks at these cities as complex environments animated by multiple communities with common problems, needs and expectations to be satisfied and improved through a net increase in resilience, liveability and expertise. Currently, cities tackle problems of pollution, energy consumption and overcrowding, risking to become unsafe and unhealthy place to live. MAtchUP foresees dedicated actions to improve the share of renewable energy, increase the sustainable mobility and invest on technology. The aim is to repaint cities with brighter solutions at the disposal of their smart communities. These solutions will boost local economies and their quality of life. Furthermore will serve as model for replication in other cities and will lead to a urban transformation driven by citizens and stakeholders.
