Published in the journal Nature Scientific Reports, the findings of the Rise and Fall Project at Utrecht University are clear: the growing threat to the Mekong Delta – and the communities, cities, rice fields and biodiversity that depend on it – posed by higher tides and salt intrusion is almost entirely due to the loss of river sediment because of upstream dams and sand mining in the delta.
Rising tides in the delta have major ramifications for flooding in subsiding and increasingly vulnerable cities, and river bank erosion. While sea level rise and climate change have received most attention in relation to the sinking and shrinking of the Mekong delta, the research shows that in the last 20 years, they have driven less than 5% of these trends.
