Across a narrow watershed in Asakura, a rural city in Fukuoka Prefecture, centuries-old stone channels still guide water through fields and into the river below. Today, those same systems are the focus of researchers at Kyushu University's Watershed Systems Engineering Laboratory. One of their projects aims to restore abandoned rice fields to functioning wetlands and forest habitats.
