I'll be happy to share things I'm doing, and have researched.
These things will be most important when surviving, water, shelter, food, and protection.
I live in the United States of Satan, so most of what i am planning or doing is based what my laws allow here.
If you have the ability too, get to a place away from the city but not to far from the city, get an acre or two of land. like for me, I am located within a walking distance of a cave and of spring water, yet im not in the city but if i had to go to the city its about 20-60 minutes depending on what city i go too, travel by car. I have a city i can get to by walking within half a day.
Either way whether you live on a little bit of land or you only have space inside an apartment, definately store three things long term. rice and water, beans can also be bought cheap and will last. you can get 5 gallon buckets, and mylar bags for cheap, to store the rice and beans in. also i suggest bying 25 lbs of salt whole sale and storing that away too. atleast get yourself a years worth. rice for 25 lbs is like 10$ if you know where to look, and salt is pretty cheap as well.
Get a book on Foraging in your area, as in what wild vegetables and plants are edible, and get a book on how to set up traps, fishing, and wildlife traps. I also recommend a basic survival book.
this is important because with this knowledge even if you run out of food and have to leave for some reason, you can still survive on the road. also if you place on traveling always travel light, perhaps only travel with a water straw, and a hammock-sleepignbag / tools / the know how to set up camp and capture you own food. however safest method is to build up your home.
I mentioned water straws, these can be purchased cheaply online and will be a life savor if you only have dirty water to drink and i highly recommend getting yourself 10-100 of these. it also doesn't hurt to set up a rain filtration system if you have the property or balcony to do it
On my 2 acres, im in the process of creating a hedge around my property of sturdy clumping bamboo, the timber kind used for wood. and the edible kind to have another source of food.
keeping your privacy with a fence of some kind is a safety tip, its always smart to try and hide your property, and if you do it with bamboo the right way you can make it look semi natural and tough enough for people not to want to bother getting through.
the next privacy tip I am implementing is excising my 2nd amendment right and buying more guns, the only thing safer than more guns is having more people you trust. i have my two uncle and their wife n kids living with me on my property and they are survival nuts. as well as they have a lot more weapons than i do.
I have you're standard pistol and shotgun for self defense soon i will be getting a rifle of some kind. stock of up on ammo now while you can.
make friends with your neighbors without letting them know about your spiritual beliefs. set up trades with people who grow locally, for example if you have a garden start trading with other people and get a friendly reputation with them, i know a few of my neighbors around here, and they are all gun holding survivalist who live the american dream of living off their land. you may not be as lucky as i am to be in an area like i am if you can't get to a place like this knowing you lives around you and making friends is still smart to do. the chaos that follows after shit hitting the fan, having well built relationships with people you know will be important as friends will be a powerful asset of them-self.
get yourself a printer and start printing off as much of the Satan's Library as you can, if you can't write down in notes the most important things and hide the notes away. keep the documents safe. i recommend printing two copies and putting one copie in a vacuum sealed bag out of light, somewhere dark, and safe.
if you have a physical hard drive that etchest information onto a disk manually these will hold information on them a lot longer than a flash or sdd will, without having power too them. make yourself a faraday cage (literally a metal box with no holes or metal not touching. no leaks so to say. this will keep the harddrive safe in the case of an EMP bomb dropping and a physical driving like that will possible work for a decade without corruption and power if properly stored. unfortunately flashdrives and sd cards will not hold information for more than a year or two without getting corrupted without plugging them in.
Besides saving up food, storing it properly, and getting water. if you are like me and have been blessed with land, use that land.
For me I'm in the process of building a pond that can hold 1000 fish.
I already have whats called an aquaponics system, but the system can only hold 50 fish or so. So my families, and pets, ,cannot have fish very often, too change this, i'm building a pond and tying this pond into my aquaponics system, so that i can grow vegetables and fruits with the fertilizer and waste product of the fish being transfered to the plants. its a very complicated system to some people, and it took me a long time to research the best way of doing it.
Always filter the solids before the hit the grow medium, you can do this serval ways. i suggest going over to youtube and watching a 100 or so aquaponic system videos. specifcally commerically done ones, as they are doing it the right way most of the time.
There is one system i am tryin to copy that produces 400 lbs of vegetables every two weeks. i won't be any where close to being able to do the same until i get my fish and pond going. because you need about 1000 fish or so to feed the vegetables.
as for what to feed the fish, i have a worm farm that is pretty easy to keep going.
when i first moved here the land was shit. I then got with the local tree guys who cut every close to power lines down. most of it is safe, and hasnt seen chemicals. so I used this to cover my land, they just come by and drop a bunch onmy property whenever i call them for free. it saves them time and its free mulch.
this mulch you can till into the land, or use it to keep weeds from growing near your veggies. but whats also very useful is its good worm food.
on a corner of my property i'm making worm farm, there's many methods out there but using used bathtubs or any big container without any way for the worms to escape will work. keep it shaded, and most worms will eat a pound of their weight. so if you have 100lbs of worms they will eat a 100 lbs of material in a week or so. this is one of the best way to not only feed your fish but to get free fertilizer for anything you're growing in the grown, worm castings will be produces and you can sell/ trade them with anyone. also add worms to your soil around you garden you have in your yard.
i suggest doing a little of everything like i am doing. I am working not only on the aquaponics system but a few gardens around my house. you can never have too much food growing.
to keep the aquaponics system running you can buy one solar panel, connect it to a tesla battery bought online, with voltage regulator and with some kits you can research and buy and set up yourself. you can have constant power going to a water pump, and the water pump is all you need with aquaponics to keep running. which will forever keep going until the pump dies. so maybe keep a few spare pumps on hand they range from 30-300 depending on the size of pump you want.
if you live near a river, you can also you the natural flow of the river to create rampump system that can create a permanent way to water you plants and to bring you water without ever having to need electricity.
I still suggest collecting and filteriing rain also buy a bunch of water filtration staws.
get yourself an alarm, probably best alarm is a well trained attack / guard dog. not only is it not that difficult to do, but gives your pup meaning to their life, giving them fulfillment and happiness in the process. just read a few books about it.
if you can't get yourself guns. buy yourself Bear Mace. stronger than actual mace and most cans will fire 5-10 or more meters
after i get my worm farm going and vegetble farm going within this year, i'll have an easily accessable way of maintaining and feeding ducks/ or chickens whichever i decide to have. i would go with chickens if you want eggs everyday. and ducks if you want to try and sell meat/trade meat. as its more expensive.,
make a gate, i have a gate to my property, its nice and all my dogs alert me anytime anyone comes close.
very important don't let to many people know how much stuff you have or your operation,hence why privacy is important.
natural hedges are the easiest fences to make.
after reading those books, start practicing foraging right away, take mental notes of where things are growing.
not many people will be doing this .
I would start preparing a life with limited electricity.
also buy a generator. propane or gas whatever you can get.
you can try to make a steam generator using wood and fire, if you are an engineering man the plans and know how are out there.
Stay safe brothers and sisters, HAIL SATAN
