Is There a System of Global Government to Organise Food Aid?

Is there a specific situation that can organize the response, or does it all end up kind of being at ha? And does the help necessarily even come in the form of direct aid? Or ar there more sort of creative financial solutions being cooked up. There's a huge spectrum here. When you're talking about acute famine, starvation conditions, that generally goes hand in hand with state failure. The problem is, how do you constitute a government machine at all to ensure that people don't starve to death?
