An increasing number of governments around the world are urging their citizens to prepare for major emergencies by keeping essential supplies at home, including food, drinking water, medicine, and other necessities. The recommendations are becoming increasingly consistent: households should be prepared to sustain themselves independently for at least 72 hours, or three days, in the event of a major disruption.
As highlighted in an OffgridSurvival report, the United States and Britain have been among the countries issuing preparedness guidance, with Japan and Finland also emphasizing the importance of having emergency provisions available. These recommendations come amid growing attention to the potential impact of natural disasters, infrastructure disruptions, cyberattacks, geopolitical tensions, and other large-scale emergencies.
In Britain, the government launched its Be Ready campaign on October 22, 2026, advising households to stock up on three days of food and water. The recommendations include approximately nine litres of drinking water per person for three days, non-perishable food, blankets, cash, a first-aid kit, a flashlight, batteries, and a battery-powered or wind-up radio. The government wants households to be capable of managing independently for 72 hours if essential services are disrupted.
Japan has also issued an important preparedness appeal. On November 2, 2026, its newly established Disaster Management Agency called on citizens to strengthen their preparations for major disasters. The government specifically recommends maintaining at least three days of food and water, preferably one week, alongside portable toilets, household necessities, and emergency evacuation supplies. The Japanese authorities identify potential threats including major earthquakes, a possible Nankai Trough earthquake, a Tokyo-area earthquake, and a Mount Fuji eruption.
Finland, meanwhile, has official guidance recommending that households maintain emergency supplies sufficient for at least three days. Its recommendations include drinking water, food, essential medications, flashlights, batteries, radios, and backup power supplies. The Finnish authorities explain that having these provisions allows people to manage independently while emergency services work to restore normal conditions and assist those most in need.
This is not limited to individual countries. In March 2025, the European Commission introduced its Preparedness Union Strategy, encouraging citizens throughout the European Union to maintain enough essential supplies to survive for a minimum of 72 hours during an emergency. The strategy specifically identifies natural disasters, cyberattacks, geopolitical crises, and possible armed aggression among the risks that require greater preparedness. Reuters reported that the recommended emergency kit should include food, water, a flashlight, a power bank, a radio, cash, and necessary medication.
The repeated message from governments is clear: people should not assume that electricity, running water, transportation, communication networks, supermarkets, and other essential services will always be available during a major emergency. Households are being encouraged to take responsibility for their own immediate needs rather than depend entirely on outside assistance.
What should households have available?
Drinking water (at least 3 litres per person per day).
Non-perishable food and canned goods.
Essential medications and a first-aid kit.
Flashlights, extra batteries, and candles.
A battery-powered or hand-crank radio.
A fully charged power bank and backup charging options.
Cash in small denominations.
Hygiene products, toilet paper, and portable sanitation supplies.
Warm clothing, blankets, and basic emergency supplies.
Copies of important documents and emergency contact information.
One important observation: These recommendations do not establish that a particular emergency is imminent. However, when governments across multiple regions independently emphasize the need for households to prepare for disruptions lasting several days, it is worth paying attention. Being prepared is not about living in fear. It is about awareness, self-reliance, and taking reasonable precautions before circumstances require them.
