In the globalized and globalizing world, questions we ask ourselves about the policies that should describe or manage the flows of people are increasingly numerous. Political conflicts, social and economic changes, trade and diplomatic agreements result in migrations, sometimes voluntary, sometimes forced. Situations, such as Brexit, the Trump Wall or the North African migration routes are just three examples of the diversity of situations we regularly face.

Countries have to deal with situations that challenge them, that undermine their status quo. There are demographic changes, new religions, age pyramids that modify their form, new beliefs and economic and work opportunities. Problems and opportunities that are not new, not in vain have new lands and new peoples been sought for centuries. Today the information we have is enormous.

Knowledge, too, but it must be ordered. We would like to have discussions among all the challenges faced by governments, institutions and citizens who have to live with these changes.
