Mekong Delta / 湄公河三角洲

The Mekong Delta / 湄公河三角洲 is the downstream case in EP267 踏访湄公河：雨季、婚飞蚁与水利帝国. The episode contrasts it with upper-river travel and Angkor history: the delta becomes a rice-rich region through later migration, Vietnamese expansion, Chinese settler involvement, and especially French colonial canal and reclamation work.

For the wiki, the delta matters as a Mekong Delta Colonial Canal Agriculture / 湄公河三角洲殖民沟渠农业 case. Canal grids and rice fields made large-scale production possible, but the same engineered landscape is vulnerable when freshwater flow weakens, sea water pushes inland, climate changes, and natural river meanders or mangrove buffers are simplified.
