Of seven new dams planned in Laos, at least four are co-financed by Chinese companies, according to Mekong Dam Monitor data. 'WAKE-UP CALL'Farmers in the Vietnamese Mekong River Delta region were not prepared for the speed at which their landscape - and fortunes - have changed. The Mekong River Commission estimated in 2018 that total sediment flow by now would be around 47 million tonnes per year. "Mainstream dams catch everything," said economist Brian Eyler at the Stimson Center, which runs the Mekong Dam Monitor. The Xayaburi and Don Sahong dams in Laos are the most recent to come online, with Xayaburi the largest on the entire Mekong River.
