Earlier this week, world leaders gathered at the United Nations to take action. So did 51 U.S. firms in a display of true corporate leadership because, simply put, a crisis of this scale requires all hands on deck --governments, foundations, international organizations, and, yes, the private sector.

World leaders meeting at the United Nations starting on Monday will try to make progress on two intractable problems at the top of the global agenda — the biggest refugee crisis since World War II and the Syrian conflict now in its sixth year, which has claimed over 300,000 lives.

Utah, a spacious state crossed by mountains, valleys and desert, takes in more refugees than some U.S. states with much larger populations. “It’s perfect here,” says Nour Eddin Abdul Bari, who worked as a chef and restaurateur in Damascus before fleeing Syria. He lauds the medical and education services provided for three of his five children with special needs.

Social media does more than share information about Syrian refugees; it offers ways you can help them. Here are five ways that highlight how social media supported Syrian refugees. [...] Since the crisis began, the U.S. has contributed more than $5.1 billion in humanitarian assistance to people affected by the conflict in Syria.

Global challenges that affect millions of citizens and nations must be examined collectively, inclusively and jointly. The large influx of migrants does not represent a single isolated issue that can be easily dealt with, but rather demands greater efforts. The United Nations can provide a more robust platform for addressing the migrant crisis. All nations together must participate in addressing and offering support to refugees and the host nations.

These images are taken from Refugee, an exhibition at the Annenberg Space for Photography in Los Angeles. Five acclaimed photographers captured images in Bangladesh, Cameroon, Colombia, Croatia, Greece, Burma, Serbia and Slovenia of people forced from their homes and looking for safety and the possibility of starting new lives.

Refugees can be an economic boost, not burden, to the communities that host them, a new study by the United Nations concludes. The benefit is bigger if refugees are given cash stipends instead of food rations, according to a joint project by the World Food Programme and researchers at the University of California Davis. The team studied Congolese refugees living in three different camps in Rwanda.
