Flood waters engulfed the home of Nowshera resident Yar Mohammad. Many families are struggling to rebuild their homes, their efforts hampered by the cost of bricks, which has doubled. According to Oxfam, 800,000 families lack permanent shelter

Last year, the Pakistan army dropped water rations to flood victims as part of an emergency relief operation. The same field now offers a relatively serene setting, but malnutrition has become a major problem. More than a million people require food aid
