Southern China
In Southern China, crop condition was below average over the reporting period. For the region as a whole, precipitation (RAIN) was 8% above average, with precipitation departures for each province as follows: Fujian, -3%; Guangxi, +21%; and Guangdong, +11%. Temperature (TEMP) dropped by 1.0°C on average, and radiation (RADPAR) decreased by 4%. Potential accumulated biomass (BIOMSS) was largely unchanged in Southern China.
The NDVI development graph for Southern China indicates that crop condition in the region was below average over the entire period. Although almost all of the cultivated land has been planted crops, the Cropped Arable Land Fraction (CALF) was still 0.5% lower than the average level. Spatial NDVI patterns and NDVI profiles showed that crop condition is generally below the average during monitoring period, except for the central part of Guangxi and central and western of Yunnan. Over the reporting period, 16.1% of the cropped area hadabove average condition, while about 14.7% of the cropped area continued to be below the average, sporadic scattered throughout the region.
Based on the above analysis, the yield of crops in this region is expected to be below average in 2017.
