KHARO CHAN, Pakistan: Salt crusts crackle underfoot as Habibullah Khatti walks to his mother’s grave to say a final goodbye before he abandons his parched island village on Pakistan’s Indus delta. Seawater intrusion has triggered the collapse of farming and fishing communities in the area. “In the evening, an eerie silence takes over,” Khatti tells AFP. “The village is desolate and we feel terrified here.”
