With the collapse of the Soviet Bloc and its economic support in 1989 as well as the tightening up of the US economic embargo, Cuba suddenly plunged into its worst economic crisis since the 1959 Revolution. Officially dubbed the Special Period in Time of Peace, the ongoing economic crisis has had a devastating impact on Cuban food security. Cuban agriculture, which was highly dependent on chemical inputs from the Soviet Union, suddenly confronted a reduction of over 50% in oil, fertilizer, and pesticide imports. Meanwhile, food imports also dropped off as Cuba's total import bill shrank by up to 70% between 1989 and 1993. As Fidel Castro himself stated in 1991: "The food question has the number one priority."
