[SYR] SYRIA

Apart from legumes, barley and wheat are the main crops in Syria. Planting of the cereals starts in November, as soon as soil moisture conditions become favorable. The proportion of irrigated cropland in Syria is about 44%. Cereal production depends on sufficient rainfall.

Compared to the 15-year average, accumulated rainfall was less than average (RAIN, -22%), while radiation was above average (RADPAR, +3%). The temperature was above average (TEMP, +0.4°C). The average temperature value for the reporting period was 11.5°C. The precipitation was generally below average except in early February, mid March and April. The temperature was generally above average except for early February and late April. The drought conditions resulted in a decrease of estimated BIOMSS by 13%. According to the NDVI profiles, the national average NDVI values were far below the 5YA during the growing period of barley and wheat except in late March and April. The national average VCIx was 0.66 and CALF was above average by 12%. Conditions for cereal production in Syria were favorable (CPI=1.11).


Regional analysis

Based on cropping systems, climatic zones and topographic conditions, five sub-national agro-ecological regions can be distinguished for Syria, among which three are relevant for crop cultivation: The first (a) (220) and first (b) region (221), the second region (222), the third (223) and the fourth region (219).

In the first two regions (a and b), the accumulated precipitation was below average, and the temperature was almost close to average. The RADPAR was also close to average. The hot and dry weather resulted in a decrease of BIOMSS by 13% to 18%. The national average VCIx values were not higher than 0.83 for the two regions. Compared to the other regions, the higher CALF values indicated more agricultural activities in this region, for a region was the same and for b region was above its 5YA by 1%.

According to NDVI profiles of the two regions, crop conditions were mostly below the 5YA. But they surpassed it by the end of this monitoring period (late April) for a, b zones. The conditions for barley and wheat production were not favorable.

Agro-climatic conditions in the second, third and fourth region were also unfavorable. The rainfall was below average by more than 17%, whereas the temperature and RADPAR were above average. The low rainfall led to a decrease of potential biomass by at least 10%. The CALF values in the three regions decreased significantly by more than 11%. The average VCIx value in the second region, the third region and the fourth region was 0.65, 0.57 and 0.56. According to NDVI profiles of three regions, crop conditions were below the 5YA except for April. Due to the severe rainfall deficit and high temperature in the main growing period, the growth of wheat and barley in the second region is estimated to be similar to average, and the conditions for barley grown in the third was not favorable either.
