Polygamy in the Negev

Haaretz highlights some ads that have been appearing in the Negev:
Over 30 and single? Try polygamy
"Local Bedouin newspaper sparks calls on single Bedouin women who are over 30 to consider polygamous marriages, saying 'it's the Sharia solution'"

A related story concerns underage marriages ("Barely sixteen and married"), and includes this  observation
"The girls themselves, explains ElKranawi, are willingly marrying at such a young age: "Girls only 15 years old dream of getting married, because they understand it to be the way to independence. After all, if you are 20 or older, you may be married as a second wife. Even if a woman has obtained an education, she will not be independent. Her parents will continue to make decisions for her."
