At age 11, Ghulam was married off to 40-year-old Jaiz in a rural Afghan village, making her only one of more than 10 million young girls who are being forced to wed men old enough to be their fathers of grandfather every year.

In an effort to start a global conversation about the devastating effects of early marriages, which are currently practiced in more than 50 developing countries, the United Nations designed October 11 as International Day of the Girl Child this year.

Although child marriage is against the law in many countries, and international treaties forbid the practice, it is estimated that about 51 million girls below age 18 are currently married, often under the cover of darkness and in secret. In Afghanistan alone, it is believed that approximately 57 percent of girls wed before the legal age of 16.

Various factors drive parents of child bridges to marry off their daughters, from the community’s pressure to confirm to age-old cultural customs to economic considerations. In poor, developing nations, it is not uncommon for families to settle debts by offering their daughters as payment.

Experts agree that early marriage denies the girl education and robs them of their childhood because most young wives, burdened by grownup responsibilities, do not get a chance to interact with their peers or carry on friendships outside the household. In many cases, the girls are lorded over by their husbands and in-laws, leaving them vulnerable(易受伤害的) to domestic violence as well as physical, sexual and verbal abuse. Underage wives who are lucky enough to escape from their husbands end up living in poverty, or worse. Most girls who enter early marriages are expected to get pregnant right away, which often leads to tragedy for both the mothers, who are still children themselves, and their babies.

Unless international organizations take steps to reverse the troubling trend, it is estimated that over the next decade, 100 million more girls—or about 25,000 girls a day ---will marry before they turn 18.
