> Avoiding risk for these farmers comes in two main forms: there are strategies to reduce the risk of failure within the annual cycle and then strategies to prepare for failure by ‘banking’ the gains of a good cycle against the losses of a bad cycle.
> If you only farm one crop (the ‘best’ one) and you get too little rain or too much, or the temperature is wrong – that crop fails and the family starves. But if you farm several different crops, that mitigates the risk of any particular crop failing due to climate conditions, or blight (for the Romans, the standard combination seems to have been a mix of wheat, barley and beans, often with grapes or olives besides; there might also be a small garden space. Orchards might double as grazing-space for a small herd of animals, like pigs). By switching up crops like this and farming a bit of everything, the family is less profitable (and less engaged with markets, more on that in a bit), but much safer because the climate conditions that cause one crop to fail may not impact the others.
Under "Banqueting the Yields":
> The most immediate of these are the horizontal relationships: friends, family, marriage ties and neighbors. While some high-risk disasters are likely to strike an entire village at once (like a large raid or a general drought), most of the disasters that might befall one farming family (an essential worker being conscripted, harvest failure, robbery and so on) would just strike that one household. So farmers tended to build these reciprocal relationships with each other: I help you when things are bad for you, so you help me when things are bad for me.
You might notice that this is exactly what I said above. What did you want me to see?
