Every three seconds, a girl is forced into marriage, according to Unicef figures. Robbing children of agency and bodily autonomy, the practice also undermines their emotional, sexual and reproductive health. Dr Faith Mwangi-Powell, CEO of Girls Not Brides, says that progress is happening, but stronger legislation is needed to enforce the laws. She also stresses the need to safeguard girls' education, whose absence often leads to child marriage.
