We live in a world of greatly increased mobility—of information, of goods and services, and of the world’s 8 billion people. We move for all sorts of reasons, and that movement can create challenges—but also opportunities. In fact, could a world on the move provide solutions to some of the challenges we face?

This week, hosts Lizzie O’Leary and Ayesha Hazarika talk to Parag Khanna, author of Move, a book that examines current trends shaping migration and its historical precedents, and predicts an increasingly mobile future. Dion Shango, PwC’s territory senior partner for Africa Central and Southern Africa, discusses how those trends are playing out now—and what business should do to adjust and prepare.
