Migration and displacement can be extremely disruptive events in a person's life. Migrant and displaced girls are among the most vulnerable and are affected disproportionately,with severe impact on their physical and mental health,welfare and successful transition to adulthood. Research shows that migrant and displaced girls are aware of the risk of violence and abuse on their journeys,yet they still embark on these perilous journeys due to grinding poverty,conflict and/or gender based inequity. In this brainstorming lab,we will bring together civil society, international organisations,migration experts and former migrant girls to discuss key and unique risks and vulnerabilities of migrant and displaced girls,key challenges faced by humanitarian and development actors in protecting girls on the move,and showcase best practices and measures to mitigate these risks and challenges. This session is organised by Save the Children in partnership with the Danish Refugee Council,IOM and UNICEF.
