Regional drought risk assessment in the Central Highlands and the South of Vietnam
This study contributes to a proof-of-concept comprehensive drought risk assessment for Vietnam by (i) incorporating drought exposure and vulnerability based on specific socio-economic conditions of the regions; and (ii) using satellite data including World Meteorological Organization (WMO) Space...

| description |
This study contributes to a proof-of-concept comprehensive drought
risk assessment for Vietnam by (i) incorporating drought exposure
and vulnerability based on specific socio-economic conditions of the
regions; and (ii) using satellite data including World Meteorological
Organization (WMO) Space-based Weather and Climate Extremes
Monitoring (SWCEM) products, and The National Aeronautics
and Space Administration (NASA)-Enhanced U.S Department of
Agriculture (USDA)’s Soil Moisture Active Passive (SMAP) Global Data
for drought hazard assessment. Drought risk assessment which
incorporated hazard, exposure and vulnerability components was
conducted for 27 provinces from four administrative areas in
Vietnam. Drought Hazard Index (DHI) was derived using the
Standardised Precipitation Index (SPI), the Vegetation Health Index
(VHI), and surface soil moisture (SSM) to take into account the impact
of both meteorological and agricultural drought. Drought Exposure
Index (DEI) and Drought Vulnerability Index (DVI) were calculated
using statistical data of land use and socio-economic characteristics
obtained from Vietnam’s statistical yearbooks. By combining DHI,
DEI and DVI, a composite Drought Risk Index (DRI) was derived for
drought risk assessment in the selected provinces for 2020. It was
shown that the highest at-risk provinces were in the Mekong River
Delta, the agricultural production centre of Vietnam. The South East
regions were less impacted by drought compared to other regions.
The proposed comprehensive approach to drought risk assessment
in Vietnam has potential to contribute to improving drought pre-
paredness and resilience of communities at-risk. |
