From the Arab Spring and the financial meltdown to weather extremes and civil conflict, we are experiencing rapid and sometimes wrenching change that no single sector can manage on its own.

In an age when resource demand often outstrips supply, new actors and unexpected collaboration are ushering in the evolution of the social contract—the means by which societies allocate responsibility and resources for advancing the public good.

Watch the plenary addresses from the 2012 Global Philanthropy Forum Annual Conference, taking place in Washington, DC, April 16-18. The conference will explore new approaches to philanthropy that are challenging the status quo, lessons learned from the private sector, and how philanthropy can play a role in building good governance. The agenda will consider the evolving social contract in places like India, China, Brazil, Egypt, and the United States. Speakers ranging from former heads of state to comedians to social entrepreneurs will challenge attendees to think and act in new ways for social good.
