@katfeete@cstross don't forget predictable weather. "efficient" farmers rely on 6-12 month weather forecasts when planting, and dropping the reliability of those means the wrong thing gets planted at the wrong time so you get reduced yield (can be zero).
There are also "market forecasts", where farmers guess prices but often also pre-sell crops. A presold crop that doesn't exist due to the aforementioned bad weather forecast costs the farmer a lot of money (see: Gamestop)
