Three quarters of the world olive is cultivated according to traditional methods. Only 26% of the surface of this crop is handled in intensive systems, which increases the production of olive oil. These are among the findings of an international study on production costs of olive oil by the IOC and coordinated by AEMO and GEA Westfalia Separator Ibérica. The report confirms major differences between the costs of one country to another. The oil yield is higher in the South of the Mediterranean and is drastically reduced in Latin American countries. The global harvest for the season in 2015-2016 will be between the 2.6 and 2.9 million tonnes. The world's largest producer, Spain is closer to 1.3 million tonnes. Argentina will increase its production to 25,000 tons, it is behind Chile (16,000 tonnes), United States (6,000 t), Peru (3,500 t) and 2,000 tons Uruguay.
