Sami Jan, a 45-year-old villager, remembers the day flash floods erupted near his fields in Balkh district, 25 kilometres northwest of Mazar-e-Sharif city in northern Afghanistan. His crops – his sole livelihood—were washed away and he was trapped in the rising water. “I had no way to escape,” said Sami. “I would have died that same day if an army helicopter hadn’t rescued me. But my crops were ruined.” Chimtal River flows through Balkh district, home to 127,000 people, mostly farmers. The river is the main source of irrigation for their farmlands, but over the past decade, flooding from the river has become more frequent and more severe, mainly due to climate change.
