The world is facing the greatest humanitarian challenges in recent memory. Around the globe, 128 million people are trapped in crisis and struggling to survive. A record-breaking 65 million have fled their homes due to conflict and violence, many of them leaving with little more than the clothes on their backs, in search of safety and assistance.

Through two new photo projects, the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) has embarked on a journey to tell the stories of people affected by conflict and natural disasters. The photos, taken by photographer Vincent Tremeau in some of the world’s most severe emergencies, aim to shed light on what it means to live through a crisis.

One Day I Will, documents the hopes of young people affected by humanitarian emergencies. Aged between 6 and 18 years old, children in different crisis-affected countries portray what they want to be when they grow up using costumes and props from their surroundings.
