The Think Tanks and Civil Societies Program (TTCSP) of the Lauder Institute at the University of Pennsylvania and Fundação Getulio Vargas (FGV) hosted the 2019 Global Think Tank Summit under the theme “Managing Global Turbulence and Transitions: The Role of Think Tanks.”The summit was held December 11th-13th, 2019 at the Fundação Getulio Vargas (FGV) main office in Rio de Janeiro, Brazil. The most influential and innovative think tanks from around the world gathered to discuss the role of think tanks in increasing global turbulence and transitions, such as navigating the new world order, popular discontent, democracy and dictators in the digital age, climate change, food and water security, trade disputes and domestic and global political tensions. This summit created a unique forum for think tanks from across each region of the world to collaborate, exchange ideas and best practices, and wrestle with the contemporary political and policy issues confronting civil society globally. Its diversity and collaborative format fostered an environment in which think tanks challenged and learned from one another. Through constructive discourse, think tanks reflected on their work thus far and collaborated ways in which they can better approach the current contentious political and social climate. The summit aimed to provide think tanks reinvigorated drive to engage in quality research and analysis practices to confront present-day challenges.
