CAN THO, Vietnam, March 24, 2023 (AFP): As a child, Dong Van Canh watched while the rice fields of Vietnam's Mekong Delta were set alight to make way for the next crop, blackening the sky and flooding the air with potent greenhouse gases.
Rice -- Asia's principal staple -- is to blame for around 10 percent of global emissions of methane, a gas that over two decades traps about 80 times as much heat as carbon dioxide.
