What should I do if there is an urban famine in the later period of civilization 5?

You can stop the population growth, or click the city name to enter the city management interface.

Then change the development to food first (balance by default)

If the scheme given by the computer is not good (such as giving priority to eating and ensuring the premise of money), you can customize your citizens.

If you don't understand, please ask. If it can help you, please adopt it. Thank you.
