A Doomsday prepper has shared survival tips for WWIII - including having a 90-day food supply and investing in communication gear.

Derrick James, 50, has been interested in prepping - preparing for emergencies by accumulating supplies, developing survival skills, and creating evacuation plans - since he was a child.

He

started building his food stockpile and making emergency plans for natural disasters and war in 2007.

With tensions rising in the Middle East and the world becoming more unstable, Derrick has shared his survival tips to use if a war breaks out.

He insists it's important to make sure you have an immediate food supply that can last you at least three months, as he believes food will be harder to come by in a disaster.

Derrick also suggests ensuring you have an updated passport and documentation in case you need to flee suddenly.

Derrick, a prepper and content creator, from rural Maine, said: "Every event that we have lived through - whether it is Covid, the Iraq war or hurricanes - brings in a new wave of preppers."

"Then the threat will go away and most people forget about it until another event comes along."

"My advice is to take a deep breath, come up with a plan that you can stick to, and don't stress yourself out."

"We are living in a fragile society and things could unravel very quickly."

Derrick insists in a crisis people will often prioritise water, but he believes food will be much harder to come by during a world war scenario.

He believes global supply chains will collapse quickly in a war, especially if trade routes close, and suggests people should stock up on foods like rice, beans, wheat berries, canned meats and ready-to-eat meals.

Derrick said: "A lot of preppers will suggest starting with water and say you can live three months without food, but three days without water - which is true."

"But anytime you get a food crisis, food is harder to come by."

"If you have food for 30 to 90 days, you can weather any storm that comes your way."

Derrick says it is imperative to invest in communication gear, to make sure you can keep up to date with the latest news alerts and instructions from the government.

He says investing in hand-cranked radios, ham radios, and walkie-talkies is a must, as cell towers and the internet could go down.

Derrick said: "The most straightforward thing to do in an emergency is to buy a hand-cranked radio - something that doesn't rely on a battery or a power grid."

"You can crank them up to get power, they have lights on them, and you can use them as a power source."

"Being able to have access to an evacuation order is important, whether it is a natural disaster or a war."

"Virtually every person has a cell phone, I still see cell phones as an important survival tool - I suggest people have the means to power those when the grid goes down."

Derrick believes it's important to make sure your passport and other documentation are up to date.

He said if you ever need to flee, you need to make sure that all your paperwork is in order before embassies shut down.

Derrick said: "More people are pursuing a second passport if it is available to them, a lot of countries now offer them in terms of heritage."

"This won't be an option for some people, but it is a growing topic in the prepping community."

"I'm in Maine, if something happens I'm closer to Canada, it would be faster to go to Canada than to get to any other state."

The final top tip from Derrick is to make sure you have a stash of cash to use.

In a crisis, some banks may close and limit access to your accounts.

Derrick said: "You need to protect your finances and make sure you have cash on hand."

"You need to diversify into things like silver, gold, and even crypto can be good if it is stored offline."

"If another country is part of your plan B, make sure you have currencies in those countries."

"A global war could mean that banks freeze, and ATMs go dark, and the dollar collapses."
