This monitoring period from October 2016 to January 2017 covers the growing stages of the 10th month rice, as well as the sowing of winter and spring rice in Vietnam. Most of the rice cultivation regions are distributed in the northern Red River delta and the Mekong River delta in the south. 

The fraction of cropped arable land (CALF) for the reporting period is similar to the five-year average (-2.29 percentage points). Vegetation condition indices (maximum VCI) are favorable (>0.8), accompanied by an increase in BIOMSS (+37.5%) because of the good water condition (RAIN, +74%) along with a decrease in radiation (RADPAR, -10.77%) and average temperature (TEMP, +0.70°C). Crop condition is below the five-year average, but above starting in 2017. 

Over 70% of the crop lands show average or better than average crop condition, with unfavorable crops in the middle mountain area such as Ha Nam, Hoang Mai, and Hung Yen. Overall, crop condition is assessed as average or better than average.
