That's cool and all, but where do I put all this shit. I live in a 3 room 60m² apartment with my family of four because of the insane rent. I literally do not have space to hord anything.
That sucks, I've been there. I recommend dry, cheap, bulk rice and beans. They are the best in terms of calories per dollar that you can store for a long time. Powdered peanut butter is good too. We used to cook two cups of rice and one cup of beans together in a rice cooker with three cups of water and then season it with whatever cheap dollar store spices we had. Very filling meal. The peanut butter is dessert.
Survival situation, you can easily get away with 1800 kcal/day. 4 people, 3 days = 21600 kcal.
Rice, mostly starch, around 3600 kcal / kg. So 6 kg for three days. That's 12 western or 0.6 Asian packs. Its like half a cement bag in volume.
Or you can get bulk ramen. A box of ramen has around the same size as that rice above, its 30x360 = 10800 kcal. So needs a bit more space but you can eat it raw!
Most bang for the weight/volume is fat though! Fat stores 7 kcal/g, protein and carbs just 4. And the tastiest way is nuts! So peanut butter for example. Or Snickers. You can also put peanut butter on raw ramen. Get a bag of chips too, you can use them as fire starters!
Don't forget other stuff though:
Crank operated radio
Combat first aid kit, ideally with Israeli bandages and a tourniquet
Power bank with foldable solar panel (+ all the cables you need)
Could you find room for a 20L water can or two? Many are "stackable". That will be more important than a big food cache. The main point isn't "doomsday prep" its for anyone who is able to hold out for a few days. That gives emergency services the space to rescue the truly desperate first.
They don't really care about that unless it's organized. A few fires here and there is handled by insurance and poses no threat to capital. All the more reason to get organized!
The Commission said in its new EU Preparedness Union Strategy that the bloc was preparing for risks […] including the possibility of armed aggression against EU countries.
EU tells the public to hold a 2nd job, private health insurance, and forget about summer holidays.
In fairness, the only thing many people will lack is water. It's not an exclusive stash, but in addition to what's in your cupboards.
You can get 10L or 25L quite cheaply. 1 should do per person, maybe with an extra for cooking. Or just grab some big bottles of water.
A hand cranked flashlight, candles and lighter are all a must anyhow, for a power cut. It might also be worth having a cheap camping stove tucked away.
Food wise. It's just a big bag of pasta or rice, along with some cans/jars to make it pleasant to eat. Throw in some hiking snack bars and you're sorted.
