In the next decade Howard Ruff warned about socio-economic collapse in his 1974 book Famine and Survival in America. Ruff's book was published during a period of rampant inflation in the wake of the 1973 oil crisis. Most of the elements of survivalism can be found there, including advice on food storage. The book championed the claim that precious metals, such as gold and silver, have an intrinsic worth that makes them more usable in the event of a socioeconomic collapse than fiat currency. Ruff later published milder variations of the same themes, such as How to Prosper During the Coming Bad Years, a best-seller in 1979.
For global catastrophic risks the costs of food storage become impractical for most of the population [54] and for some such catastrophes conventional agriculture would not function due to the loss of a large fraction of sunlight (e.g. during nuclear winter or a supervolcano). In such situations, alternative food is necessary, which is converting natural gas and wood fiber to human edible food.[55]

I know of another room which may have been thought of as a bunker…or maybe not. A couple built a house with a full basement and an attached two car garage which has a concrete slab floor. Under that slab is a ‘storage room’, entered from the basement, but it has a concrete wall between it and the rest of the basement, and a steel door which opens inward. Sound like a bunker?
If you just need to cover one person for two weeks in the cheapest way possible, you can buy one bucket for $130 and stretch the 27,330 total calories an extra day or two at 1,900 calories per day instead of the usual 2,275. Or buy two buckets for the cheapest way to cover two people. But we’d recommend a minimum of two buckets regardless, even for one person, just for redundancy and the unexpected.
I know how you feel when you get that urgent feeling that what you have is not enough. Shelly (the Survival Husband) and I were just talking about this last night. In my mind, I know that I have a lot but I keep purchasing more. Luckily, like you I am good at food rotation although I do have a lot of #10 tins and properly packaged buckets in deep storage as well. Those do not get rotated.
In one instance, a very savvy young man advised his fellow apartment dwellers to take shelter in an underground tunnel that connected their apartment to the outdoors. Clearly, this young man had taken notice of this tunnel and thought about how and when it could come in handy. WMD (Weapons of Mass Destruction) expert, (Ret.) Army Chemical Expert, Major David L. Jones, insists that even a nuclear event is survivable if you have planned, prepped, and know what to do.
2. At least two ways to cook food in a power down situation.  I’ve used the Sun Oven for years (visit the official website here) and own the Stove-Tec Rocket Stove.  The Eco-Zoom stove is another version of a highly effective, fuel-efficient stove that weighs less than the Stove-Tec.  If the prices of energy skyrocket, and it looks as though that may happen in the near future, it will be a blessing to have alternative ways to cook food without cranking up the gas or electric range.
When speaking to preppers like Jennifer, Luther, and Nygaard, it can be hard to separate the more practical aspects of the lifestyle from the enjoyment that comes from doing things yourself instead of paying someone to do them. When I point out that running a small-scale farm and caring for two kids seems like an awful lot of work to do on top of a full-time job, Nygaard demures. “Yeah, it is. But I choose it. I choose to spend it like this because there are things that give me pleasure. I enjoy canning. I love seeing my work on the shelf. You grew that, and you canned it, and you get a source of pride from that.”
This article from OffGridNews. What initially caught my interest with this article was how he feels the same about how the show Doomsday Preppers exploits preppers and perpetuates the stereotype by making all preppers look  like crazy off the wall people. Although I do have my days, I am not a social outcast waiting for the end. Preppers are not hoping a disaster will happen, we are preparing just in case. When something catastrophic happens, we will not be as “shocked” and therefor better prepared.

Water is pumped from two water wells, reaching thousands of feet deep into an artesian aquifer, then stored within the massive underground, reinforced concrete water tanks, with a water distribution system being deployed to each bunker. Each bunker is buried and protected under thick berms of earth, with extensive grading for drainage, across the gently sloping grasslands.
Each of us has personal fears. It might be poor health. It might be a precarious job situation. There are a great number of individual calamities that can befall us, however, the fact that you have just been fired from your job, while I am concerned as I would be for anybody who has lost employment through no fault of his own, it doesn’t affect me. It doesn’t affect my neighborhood. It doesn’t affect the distribution of food and utilities.
Cooking fats can be substituted in most cases with the exception being frying. Some oils and fats have a lower smoke point than others. I have never had any luck using olive oil for trying to fry potatoes to a crispy state but grape seed oil, peanut oil, or lard does just fine. Pie crusts made from lard, flour, salt, and a little water are really good. You really don’t need butter to make a flaky crust if you have lard.

3. Supplies for bartering: These are my lowest priority but it never hurts to have a little extra of something that could be useful for bartering in the future. But remember your situation is different from mine. You might not have the room to store hundreds of gallons of fuel or water, so you might want to stockpile supplies that take up less room like batteries, lighters or water purification tablets that can be used to barter with in the future.
This is a really comprehensive article on food prepping! I was very taken by your last item on “Edible Landscaping.” There is a natural antibacterial, antiviral product called “Sambucol,” that is a syrup (patented) made from black elderberries. There is another syrup similar called “Sambucus,” which is the botanical name for black elderberries. Not only do they taste delicious — like something to top your ice cream sundae with! — they are pretty amazing for coughs, colds, and flu. I am thinking that that might be a good thing to have growing in our yards when SHTF.
I would contend that most (if not all) “long shelf life” dehydrated/freeze dried food products fail to deliver the calorie and protein count that is required to survive. It is far more likely that you would have to double the quantity and cost to actually achieve any specified duration. If you don’t believe me, just examine the details in their advertising.
One major upside of freeze-dried food is its convenience. Since all its water content has been removed—via a process that involves exposing food to subzero temperatures, while removing the resulting water vapor with a vacuum—it’s easier than canned goods to transport on the fly. To “cook” Wise Company’s six-grain Apple Cinnamon Cereal, you just boil three and a half cups of water, dump in the powdery contents of the bag (minus the oxygen absorber), and cover the pot for 12 to 15 minutes.
