Today’s most urgent problems, from food security to global warming, are fundamentally global. They require nothing less than concerted, planet-wide action if we are to secure a long-term future. But humanity’s story has always been on a global scale. In his new book The Ages of Globalization, Jeffrey D. Sachs, renowned economist and expert on sustainable development, turns to world history to shed light on how we can meet the challenges and opportunities of the 21st century.

Sachs will take us through a series of seven distinct waves of technological and institutional change, from the original settling of the planet by early modern humans to today’s globalization. The dynamics of these past waves offer a fresh perspective on the ongoing processes taking place in our own time. Sachs emphasizes the need for new methods of international governance and cooperation to prevent conflicts and to achieve economic, social and environmental objectives aligned with sustainable development.
