The monitoring period corresponds to the harvest of Kharif crops. The assessed crop condition is poor, and reduced output is expected primarily due to the below average rainfall and decreased area of cultivated land. Noticeably, crops in the south Indian states are in poor condition. During the monitoring period the country experienced 30% less rainfall (RAIN) than expected, including Andhra Pradesh (RAIN, -71%), Assam (-7%), Bihar (-23%), Chhattisgarh (-25%), Goa (-69), Jharkhand (-58%), Kerala (-62%), Karnataka (-74%), Maharashtra (-42%), Madhya Pradesh (-34%), Nagaland (-15%), Odisha (-28%), Tamil Nadu (-60%), and West Bengal (-18%). The national biomass accumulation potential (BIOMSS) is -20% below the previous five-year average and linked to the poor performance of rainfall. All of the mentioned rainfall deficit states experienced low BIOMSS ranging between -17% and -64%. Crop condition development was below average during October to November, but turned average starting in early December. The NDVI values and spatial NDVI patterns were average over the country except in the south Indian regions. Again, the maximum VCI values were below 0.5 in south Indian regions, confirming poor crop condition. The crop arable land fraction (CALF) dropped by -0.56 percentage points compared to the previous five-year average. Temperature (TEMP) was average, while photosynthetically active radiation (RADPAR) was +3% above average. Damage caused by floods in previous months (reported in the November 2016 bulletin) along with the present condition of deficit rainfall altogether result in poor crop condition for the country. Reduced output is expected.
