After the impact event of 1159 BC there were 20 years of no harvests in the Near East. People did survive, but it seems primarily in places like Egypt where they could survive off the Nile River. It is precisely why moving the headquarters of royal operations to Egypt after this catastrophe would have made good sense, and why there was such a priority during the dynastic period on grain storage (that could last a minimum of seven years).
