From the earliest theoretical generalizations, migration has been linked to broader geographical, social, economic, historical, cultural, and political contexts. Today, mobility and migration are increasingly intertwined with the extraordinary acceleration of change in geopolitics, the environment and ecology, as well as technology. Unlike the well-known notion of the “age of migration,” which described the intensification of mobility at the beginning of the twenty-first century – when the mass circulation of people, goods, capital, and information rapidly expanded under conditions of globalization – different conceptual frameworks are now in circulation, such as the “age of accelerations,” the “fourth industrial revolution,” and the “age of change.” These strategic transformations call for contemporary migration and mobility flows to be understood both in light of major geopolitical developments and the growing influence of climate-related issues, as well as the increasingly significant penetration of digital technologies into all phases of migration processes. In the book Risks and Opportunities of Contemporary Migrations, the authors seek to address these aspects of migration through an empirical analysis of virtual networking and diaspora social capital, as well as emerging dimensions of climate mobility.
