Join the Roberta Buffett Institute for Global Affairs and the Roberta Buffett International Studies Program for a lecture by Sheldon Yett, UNICEF Representative to Sudan and 2026–27 Roberta Buffett Visiting Professor of International Studies, on why we paid attention to Darfur 20 years ago, why we need to pay attention to a much larger war sweeping Sudan and the region today, and the consequences if we fail to do so. After his short lecture, Sarah Deardorff Miller, Senior Fellow at Refugees International, will moderate discussion and audience Q&A. 

Doors will open at 12:00 p.m., and lunch will begin at 12:15 p.m.

About the event 

Twenty years ago, Darfur dominated international headlines. Today, despite Sudan facing the world's largest humanitarian crisis, global attention has largely faded. 

The scale of the catastrophe is staggering. Conservative estimates place the death toll in the tens of thousands. Millions of people have been displaced within Sudan and across its borders, while roughly half the country's population now requires humanitarian assistance. Food systems and livelihoods have collapsed. Hospitals, schools, markets, and other civilian infrastructure have been damaged or destroyed. Entire communities are living under the constant threat of hunger, disease, displacement, and violence. 

Against this backdrop, humanitarian organizations continue to operate in one of the most challenging environments in the world, even as humanitarian and development funding is being scaled back. How are the United Nations and its partners delivering assistance on the ground under these conditions? What are the consequences of shrinking international support at a moment of unprecedented need? 

This discussion will also examine the political dimensions of the crisis. Why has there been so little sustained diplomatic engagement with the regional actors who have the greatest ability to influence the conflict? And what are the risks, both for Sudan and for regional stability, of allowing the world's largest humanitarian emergency to remain largely ignored? 

This conversation will explore what is happening in Sudan today, what the humanitarian community is doing to respond, and why greater international attention and diplomatic action are urgently needed.
