Sarey Amadou, 14, poses in her bedroom in the remote village of Hawkantaki, Niger, July 20. Even though the boy she had a crush on offered a dowry for her, her father insisted that she marry her first cousin, who lives several hours away in the larger village of Guidan Roumdji. Even during the best of times, one out of every three girls in Niger marries before her 15th birthday, a rate of child marriage among the highest in the world, according to a UNICEF survey. Now this custom is being layered on top of a crisis. At times of severe drought, parents pushed to the wall by poverty and hunger are marrying their daughters at even younger ages. A girl married off is one less mouth to feed, and the dowry money she brings in goes to feed others.
