Setting Up Indicators to Assess the Environmental Quality of Cities

Since early times, when humans started to rule over space to ensure their own survival, they have changed their environment. Their intellectual development, along with the advances of food-production and house-building techniques was the first evidence of the social organization and construction of towns (BENEVOLO, 2009). The development of towns drew more and more residents after better living conditions, on account of the offering of services, job opportunities and leisure. This way many countryside workers migrated into urban centers which went through constant changes in consolidated areas and in the untouched environment.
