[originaltext] The number of girls married in Africa is expected to double i

The number of girls married in Africa is expected to double in the next 35 years, experts say. That means almost half, or 310 million girls, by 2050 will be married before they reach adulthood, says a United Nation’s report. The African Union says it wants to end child marriage in Africa.
Delegates at a summit in Zambia are expected to set 18 years old as the lowest legal age for marriage across the continent. Marriage before age 18 is already against the law in most African countries.
    Yet the UN says more than 125 million African women and girls alive today were married before their 18th birthday. Experts say most were given to men in traditional or religious unions in violation of the law.
    African Union chairwoman Nkosozana Planum Zuma says local culture that undervalues girls and women is to blame. Poverty and lack of education are also responsible, experts say.
