Children are among the most vulnerable of the victims of war, with potential, long-term repercussions to their physical and mental health and psychosocial wellbeing. Conflicts also directly impact the wellbeing, capacity and social cohesion of families and communities charged with children’s education, protection, health, development, recovery and nurturing. Mental health and psychosocial support (MHPSS) is a core strategy in humanitarian settings in helping children to survive, to cope and recover and to thrive. The capacity of children and adolescents to grow up well and envision and realize a productive future is essential to social cohesion and creating peaceful societies moving forward.
