When investors in 2019 announced plans to build a massive hydroelectric dam on the Mekong River just upstream from Luang Prabang, the ancient royal capital of the former Kingdom of Laos, they drew a slew of criticism. So much criticism, in fact, that UNESCO—which has listed Luang Prabang as a World Heritage Site—could reconsider the status of the site at the annual World Heritage meeting that is currently underway and lasts until July 31. If the worst predictions are borne out, the environmental dangers of the dam project could lead UNESCO to delist the site, a huge reputational loss for a city whose economy depends on tourism.
