The living city - introduction to circular urban metabolism
Today the cities of the world are home to almost 4 billion people (54% of the world population) and in the coming years this number will grow considerably. Billions of tons of raw materials are used for their construction and operation, such as water, food, fuel, building materials, etc; once used, they are discarded in the environment as pollution and waste. However, resource consumption and waste disposal are not the only problems to be addressed; issues related to sustainability also include social and economic elements, such as mobility, housing availability, employment, health, education, citizen participation in decision-making processes.
This book presents the issues related to urban sustainability, proposing solutions based on the vision of the city as a "living organism".
