A short-term gas crisis or weather event will need less supplies than a long-term issue like supply chain disruptions, war, etc. Predicting world events that would lead to a food shortage is difficult, but observing the news of today would be helpful in your predictions. The climate crisis is rapidly affecting our Earth, which may push for more stocking of pantries with sustainable food products.
When determining how much food to stockpile, it is important to take into account how many people in the household would need to be fed. A family of three would need way less than a family of seven to survive. Taking into account the dietary necessities would also be a good idea. For example, a two year old and a teenager are going to need varying amounts of food and nutrition.
