Analysis of sand mining in a mega-delta using satellite image processing: Applied to the Vietnamese Mekong Delta

This study is an analysis of sand mining in the Vietnamese Mekong Delta (VMD) with the use of the optical satellite data set PlanetScope. This is done with a detection and classification model of sand mining vessels in the VMD. The classification model is based on machine-learning and it is trained with three classes: sand mining vessels, other...

Socio-hydrological approach for farmer adaptability to hydrological changes: a case study in salinity-controlled areas of the Vietnamese Mekong Delta

The Vietnamese Mekong Delta (VMD) is an example of a complex dynamic socio-hydrological system in which societies and hydrology interact and co-evolve. The dominant engineering approach in the VMD has enhanced the dynamics of society and hydrology. This study looks at the implications of socio-hydrological dynamics in the coastal VMD where...

From national vision to implementation: governance challenges in sustainable agriculture transitions in the Vietnamese Mekong Delta region

This study identifies how the governance of the transition to sustainable agriculture in the Vietnamese Mekong Delta is constrained by a lack of leadership, coordination, and funding. The Vietnamese Mekong Delta region is an important agricultural region yet highly vulnerable to climate change. In 2017, the Government of Vietnam issued...

Surface Water Mapping and Flood Monitoring in the Mekong Delta Using Sentinel-1 SAR Time Series and Otsu Threshold

The annual flood and the alteration in hydrological regimes are the most vital concerns in the Vietnamese Mekong Delta (VMD). Although synthetic aperture radar (SAR) Sentinel-1 imagery is widely used for water management, only a few studies have used Sentinel-1 data for mapping surface water and monitoring flood events in the VMD. This study...
