How did Farming change in Italy after the second punic war?
Actually Hannibal’s invasion occurred only at the beginning of the 2nd Punic War. By the end, he was alone, abandoned by his forces, pursued & killed, and his people, the Carthaginians, & their culture, were utterly eradicated from the face of the earth. The farming practices that the Carthaginians had excelled in, especially their grapes and vineyards, were basically stolen by the Romans and relocated to other parts of the Roman Empire, including Italy. I recently saw a BBC documentary on this. Not a single human being, building, book, or creature was left standing in Carthage after the Romans vented their anger for having been beaten so soundly by Hannibal in the early phases of the war. So I would say that farming practices in Italy after the 2nd Punic War, changed in that they were able to incorporate many of the more advanced techniques that the Cathaginians had developed.
