Short summary
The populous and low-lying Vietnamese Mekong delta is facing accelerating subsidence rates and effective mitigation strategies are urgently needed to save-guard the future sustainability of the delta. This paper gathers results from existing measurements and estimates of subsidence in the Mekong delta and presents new, delta-wide estimates of subsidence based on satelite measures. We outline a planned approach to advance towards improved quantitation of individual subsidence drivers.
