Rice-cropping systems in Vietnam’s Red River Delta

Intra-annual  Sentinel-1 data from January 2015 to December 2015 were used to produce rice-cropping systems map in the Red River Delta, Vietnam. In this case study, a significant area of rice paddies grows two crops per year (green). The remaining areas, in mountainous and riverine regions (red), are where the long-term flooded or saturated soil conditions permitted only one crop of rice per year.
