Daily reports of inventory shortages, rumors of war, inflation, etc. We've seen or there are predictions of shortages: food (beef, chicken, pork, grain, etc.), household goods, medication, healthcare, energy, oil, fuel, etc.
Key needs are: shelter (heat), water, food/nutrition, defense, energy, mobility. And redundancy is important.
I prep for months (and in a radical case up to 1-2 years) of sustenance supply chain interruptions, knowing that if there is more than a week or few weeks of true food shortages there will be unrest. I have a few weeks of fresh foods. I have a few months of frozen and canned foods. I have probably 2 years of long term storage dry goods, with a radical change in diet and calorie intake. This includes dry goods like beans, rice, wheat, long term packaged foods (MREs, Mountain House, etc. of which I have 100 meals of that alone, which is a year of eating 1 proper meal every 3 days to supplement all the dry goods). I have clean water drums and bladders to fill, water filtration, and can gather water from natural sources and filter. I also have 6-12 months of dog food on hand at all times. Dry food will last 6 months, canned food ~2 years. Rotation is key.
I just moved and my new home has an excellent plot for gardening and it will be on my top priority. Gardening and a few egg laying chickens are on my priority list, for food and bartering purposes.
While fuel is the weak link and hard to store, at times I've stored up to and sometimes more than 50 gallons of gas (when it was on sale for $1.60 in mid-2020, I stocked up with 20 gas cans). I also have years worth of motor oil to use, sell, or barter with.
Sanitation: Yes. I have 1-2 years worth of bar soap, liquid soap, detergents, dish soap, hand soaps, and shampoo and hand sanitizer. And probably 6 months of TP on hand at all times. Keep a bucket and shovel handy if the plumbing goes out!
Energy: I've currently got several methods of heat and ways to cook food, and will be adding a wood stove near term. Fireplace, camp stoves, outdoor fire pit, propane grill, gas generator, electric range and microwave.
Of course guns and ammunition, security measures to defend.
Community is critical, so befriend your neighbors and get to know the local farmers, buy meat and poultry directly from them to form relationships NOW. This can be critical going forward.
