History has taught our leaders the importance of anticipating and forecasting adverse meteorological conditions in the process to become natural disasters of immense proportions with tragic loss of lives and catastrophic destruction of property and cultural landmarks belonging to all humanity. Moreover, today's leaders must know how to foresee and coordinate the unstoppable dynamic of the exchange and integration of ethnic groups that inevitably become mass migrations of people looking for greater economic and social stability.
When the Urban, Regional and Land Planning Authority of the 21st century try to identify contemporary solutions to those problems, they cannot ignore what has happened so many time in the past: Temporary sheds, years after the devastating event, have become semi- permanent poor habitats , making up shanty towns and settlement camps that represent monuments of improvisation, inefficiency, unsanitary conditions, corruption and violence Furthermore, we cannot discount the fact that all new construction solutions, even if we want to call them "temporary or transitory", still make up a category of housing that must effectively and graciously welcome, with absolute security (for not always a brief period of time), elderly, women and children, victims of natural disasters in a state of chock and desperation, or poor immigrants, physically weak and mentally traumatized, or even peoples driven from their homes by acts of war or aggression.
That being said, let's try to propose solutions applicable to our century, and consider under which economic perspective, limited to which construction sector, the paradigm of Contemporary On Site Construction Automation Science could be adopted with the aim of stimulatingmodern political solutions.
It is worth the effort to analyze around the world what has been attempted in recent years during which such a paradigm can be reduced to 4 basic concepts:
1. The Concept of Mechatronic Urbanization, Created in Japan
2. The Concept of Pre-urbanizational Infrastructure, created in the USA
3. The Housing Model and Concept of "On Site Auto-Construction", born in Italy
4. The Concept of Self-Help Housing or Involvement of the Occupant
