The reporting period corresponds to the growing of Aus and planting of Aman rice. As per CropWatch indicators, overall crop condition was above average during the reporting period. However, excess rainfall (19% above average) caused flooding in Madaripur, Rangpur, Rajbari, Manikganj, Kurigram, Faridpur and Tangali districts and damaged the standing crops. The overall biomass accumulation potential (BIOMSS) increased by 6% above the five-year average while photosynthetically active radiation (RADPAR) remained low (-6%) and temperature (TEMP) was average. Compared to the previous five-year average, the crop arable land fraction (CALF) increased by 1 percentage point. The national NDVI profile remained comparable with the previous five-year average values. Over the whole country the maximum VCI ranged from 0.5 to 0.9, indicating average crop condition. Spatial NDVI profiles of the country steadily progressed during the monitoring period except in the Sylhet region where a sharp drop was noticed in August. Overall, above average output is expected due to favorable conditions of rainfall, biomass accumulation, arable land fraction, as well as temperature.
