1-  Introduction:
SOS Children’s Villages is an independent, non-governmental social development organisation that has been active in the field of children’s rights and committed to children’s needs and concerns since 1949. SOS Children’s Villages International is the umbrella organization to which all SOS Children’s Villages including SOS Children’s Villages Somaliland Association is affiliated. SOS is committed to the welfare of children – often throughout the whole of their childhood, and to strengthening families and communities as a preventive measure in the fight against abandonment and social neglect. With the SOS Children’s Village concept, the organization pioneered a family approach to the long-term care of orphaned and abandoned children. SOS Children’s Villages upholds child protection policy and our work reflects our commitment to the protection of children and youth from abuse.
