Sardinia faced the creation of military bases on the island, like Decimomannu Air Base and Salto di Quirra (the biggest scientific military base in Europe) in the same decades. Even now, around 60% of all Italian and NATO military installations in Italy are on Sardinia, whose area is less than one-tenth of all the Italian territory and whose population is little more than the 2.5%; furthermore, they comprise over 35,000 hectares used for experimental weapons testing, where 80% of the military explosives in Italy are used.
