Sicily is formed by a group of islands and together with Ustica and Pantelleria as well as archipelagos of the Aeolian, Aegadian and Pelagian, Sicily is the biggest region in Italy with a population reaching 5 million inhabitants. The economy of Sicily has deeply rooted agricultural traditions. Unfortunately, these traditions also affect the way farmers use the land. As a result, families only manage 25% of the land, employing extensive farming methods. It is followed by extremely low land fertility, which allows harvesting about 10% of potential yield. Nevertheless, even with these sad statistics, Sicily is an important agricultural hub, which produces almost all lemons in Italy, 9 million hectolitres of wine and overall 15% of the total production of Italy. Shipbuilding, machine tools manufacturing and petrochemical plants are extremely important for the Sicily’s economy. Industrial factories tend to focus around large cities like Palermo, Syracuse and Gela. Overall, agriculture and industry employ about 20% of the local population, while the service sector provides jobs to around 70% of Sicilians. The service sector in Sicily stands on the shoulders of emerging tourism, hospitality and research. Approximately 2% of the inhabitants are actually employed in the R&D branch.
