13 and a bride
Meet Mariama, 13, who has just discovered she is about to join the 40% of girls in Niger who marry before they are 15.
Early marriage can be catastrophic for girls. Many are pulled out of education and pregnancy can cause serious long-term problems - such as fistula, which leaves girls incontinent and in constant pain.
Plan is working with girls, their parents and communities to educate them about the consequences of child marriage, particularly the dangers to a girl's health if she gives birth before her body is ready.
Plan believes that sending girls to school is essential for reducing child marriage and funds 200 schools in Niger, focusing on educating girls and ending early and forced marriage.
