Will the scale of international migration increase over the coming years?

It is difficult to predict future migration trends. They will probably follow much the same pattern as today, with continued migration of inhabitants of the former colonies to the former colonizing countries, and the growth of highly skilled labour migration (managers, engineers, etc.). But unpredictable events such as civil wars, famine or natural catastrophes may well create new migration flows in years to come.
Nobody foresaw the current massive wave of migration towards the countries of southern Europe such as Spain Italy and Portugal. In the last few years, hundreds of thousands of illegal immigrants have been accepted on the soil of these former emigration countries and granted residence permits. Likewise, many migrants from sub-Saharan Africa, unable to cross the borders into Europe, finally settle in Morocco and Tunisia.
