ORGANIC CEREAL CROPS IN THE WORLD, IN EUROPE AND IN ROMANIA – COMPARATIVE ANALYSIS

Andreea Lidia Jurjescu, Florin Sala

Abstract


Organic crops have recorded variable dynamics in cultivated areas, with an increasing trend globally. This study analyzed the situation of the area (A) of cereal crops in the organic system worldwide - A(W), in Europe - A(E), and Romania - A(RO), during the 2013 – 2023 period. At the global level, there was an increasing trend in area over the study period, with a deviation in 2014. At the Europe level, there was an increasing trend in area over the period 2013 - 2020, and after the maximum in 2020 followed by a decreasing trend. At the level of Romania, there was a decreasing trend in the area between 2013 and 2016 (with a minimum in 2016), and an increasing trend between 2016 and 2023. Polynomial models described the variation of cereal crop areas in the organic system in relation to the time factor (T, years), with R2 = 0.983 in the case of A(W), R2 = 0.980 in the case of A(E) and R2 = 0.946 in the case of A(RO). According to PCA, the principal components explained 98.564% of the total variance, and Cluster Analysis grouped the years of the study period based on similarity.
