The current reporting period from January to April 2023 covers winter wheat and barley, as well as other crops (potato, vegetables, etc). The country suffers from a severe, multi-year drought, which has caused extremely low water levels in the reservoirs and depleted groundwater. This, in turn limits the options for supplemental irrigation.


Algeria suffered a deficit in rainfall (-65%), while temperature and radiation were above average (+0.27°C and +9%, respectively), which resulted in a potential biomass decrease by 41%. Agronomic indicators show that CALF fell to 36%, while VCIx reached a low value (0.45). The national NDVI development curve has been below the 5-year average since January, indicating poor crop prospects. Accordingly, the spatial distribution of the NDVI profiles indicates that it trended below the average in all regions.  The crop production index (CPI) is 0.60, this value is the lowest for this period between 2013 and 2023.
