The reporting period corresponds to the growing of Aus rice and planting of Aman. Overall, the CropWatch indicators show poor crop condition at the end of the reportingperiod. Cyclone Komen and excess rainfall (RAIN, +71%) caused flooding inChittagong, Rajshahi, Dhaka, Khulna, and Barisal and damaged rice crops. Theoverall biomass accumulation potential (BIOMSS) was 15% above average;temperature (TEMP) were average, while radiation was low (RADPAR, -9%), a very negative factor in a country where sunshine is a dominant limiting factor.Considering the previous five-year average, there were no changes in the fractionof cropped arable land. The national NDVI profile was below the average of the previous five years. In some regions of Sylhet, Dhaka, and Rajshahi. The maximum VCI recorded was below 0.5, indicating below average crop condition.However, maximum VCI values in other states ranged from 0.5 to 1, pointing to average crop condition. Spatial NDVI profiles for the whole country dropped during May to early June; however, profiles started to recover in the end of June exceptf or the areas of Khulna, Barisal, Chittagong, and the region south of Dhaka,where profiles started to improve only in mid-July.
