People leave their surroundings and move to other locations, whether it is a city or territory, be it close, far away and even in another country, and often for economic, political, environmental or by warlike conflicts. In 2018, 55% of the world’s population will live in cities and by 2050, 68% of the population will live in urban environments.

Migration is generating, and will continue to generate urbanistic, sustainability and human tensions. Migration will be a factor in tensions regarding housing, infrastructure, basic services, food, health, education, employment and security. In depopulated areas, mainly rural, deficits will be generated by the maintenance of infrastructures and public services (hospitals, schools), private services (banks, supermarkets) or investments (internet).

Cities and territories of peace must create spaces that for people who change their residence freely or that are forced to flee from poverty and hunger, from violent conflicts, persecuted for political reasons or for the defence of human rights expelled by pollution or climate change. Therefore, they must establish procedures and mechanisms to facilitate their incorporation into society: access to health, education, housing, work, among others, that provide decent and peaceful living conditions for all these populations.
