The South and Southeast Asia MPZ includes India, Bangladesh, Cambodia, Myanmar, Nepal, Thailand, and Vietnam. This reporting period covers the growth and harvest period of summer rice and maize.

According to the CropWatch agroclimatic indicators,  RAIN was below the 15YA (RAIN -10%), whereas the temperature and the RADPAR were above the 15YA (TEMP +0.2%, RADPAR +6%), which resulted in an increase of estimated biomass (BIOMSS +5%). CALF was increased by 1% compared with the 5YA, reaching 97% and the VCIx of the MPZ was 0.92.

According to the spatial distribution of rainfall profiles, the precipitation for 17.5% of the MPZ (southwestern India, Thailand, northern Cambodia, and northern Vietnam) was above the average from July to early October and reached the highest values in late September, which affected the summer rice, soybean and corn harvests. The precipitation for 14.9% of the MPZ in Central India had strong fluctuations in late September and reverted to average in early October. Heavy rainfall had caused floods in southern India, northwestern Nepal, central Bangladesh and Thailand. The precipitation for 27.5% of the MPZ (north and western India, Bangladesh, central Myanmar, and southern Laos) was below the average from July to early September and reverted to the average in late September. This negatively affected the planting of the main rice crop. The precipitation for 5.3% of the MPZ (northern India and southern Nepal) showed small negative departures from July to September and close-to-average values in October. The growing season of summer rice in southern India had been affected by drought in July. The spatial distribution of temperature profiles showed that the temperature for 13.4% of the MPZ was below the average in July, August, and October, mostly located in western India. The temperature for 13.6% of the MPZ was above the average from July to October, mainly located in central India, southern India, eastern Nepal, and central Myanmar. The temperature for 2.5% of the MPZ showed higher positive departures during this period, mainly located in northern India, Nepal, central Myanmar, and southern Sri Lanka.

The BIOMSS departure map reveals that the potential biomass in western India and eastern Sri Lanka was 20% higher than the average level, while the potential biomass in most of India, central Myanmar and western Sri Lanka were estimated to be below average. The Maximum VCI map shows that the index was higher than 1.0 in some scattered areas. Based on the VHI Minimum map, summer rice, soybean, and maize growth suffered from severe drought that was experienced from July to October, mainly in western and northern India, eastern Bangladesh, southern Nepal, central Myanmar, western Thailand, southern and northern Vietnam, and Cambodia. The CALF map indicates that most of the regions were planted except for scattered areas in India and Bangladesh. The CPI is 1.0, and the crop production situation is normal. The cropping intensity is 100 in India, Nepal, central Myanmar, Thailand, Cambodia, southern Laos, and central Vietnam. The Cropping intensity of 200 was observed form southern and northern India, southern Myanmar, central Thailand, and northern and southern Vietnam.

Overall, the crop conditions in the MPZ were generally favorable, except for areas affected by severe drought and heavy rainfall.
