Satellite Analysis for Mekong Delta, Vietnam

Name: Satalyse
Author: Satalyse

The Mekong Delta produces over half of Vietnam's rice output and feeds 20 million people, but it is simultaneously sinking at up to 3 cm per year due to groundwater extraction while sea levels rise, a compound vulnerability that makes it one of the world's most climate-exposed agricultural regions. Satellite crop health monitoring, seasonal flood extent tracking, and temporal subsidence analysis are direct inputs into delta management decisions.

10.45°, 105.63°

Tropical monsoon with a dry season (Dec–Apr) optimal for satellite imagery acquisition and a wet season (May–Nov) during which flood extent reaches its maximum.
