No crops were cultivated in most of the country during this monitoring period, except for some minor winter crops planted in the southern regions. Compared to the 15-year average, accumulated rainfall and temperature were above average (RAIN +2%, TEMP +1.4°C), while radiation was below average (RADPAR -2%). The dekadal precipitation was above the 15-year average from the mid-November to mid-January. The dekadal temperature was above average from mid-November to January. The agro-climatic conditions resulted in a minor increase in estimated BIOMSS by 2%. According to the NDVI profiles, the national average NDVI values were lower than 0.2 starting from November because of freezing conditions.
Overall, the agro-climate conditions were normal in the monitoring period.
Regional analysis
Based on cropping systems, climatic zones and topographic conditions, four sub-national agro-ecological regions can be distinguished for Kazakhstan, among which three are relevant for crop cultivation: the Northern region (112), the Eastern plateau and southeastern region (111) and the South region (110).
In the Northern region, the accumulated precipitation (RAIN +6%) and temperature (TEMP +1.6°C) were above average, while RADPAR was below average by 3%.
In the Eastern plateau and southeastern region, the accumulated precipitation (RAIN -3%) was below average, while the temperature (TEMP +0.9°C) was above average. The rain deficit resulted in a minor decrease of BIOMSS by 1%.
The South region received 125 mm of rainfall, which was the lowest amount and the biggest departure among the three regions. Due to the deficit of rainfall (RAIN -10%), the potential biomass decreased by 2%. The average VCIx for this region was 0.75 and CALF was below average by 41%.
