An extended power cut, a blocked road, an interrupted water supply: most everyday disruptions resolve themselves in under three days. That is why 72 hours of autonomy at home is the first goal of any resilience practice — concrete, achievable, and already a meaningful change.
Why 72 hours?
It is the window most civil-protection agencies plan around: the time it usually takes for essential services to come back or for organised help to arrive. Being self-sufficient through that window turns a stressful situation into a manageable episode — for you and for the people around you.
The four pillars
Build your autonomy around four needs, in this order:
- Water — plan on 3 litres per person per day: drinking, basic hygiene and cooking. For a household of four, that is 36 litres for 72 hours.
- Food — favour things you already eat, with a long shelf life and edible without cooking: tinned food, dried fruit, long-life rations.
- Light and information — one headlamp per person and a battery or crank radio. When the network is down, radio remains your link to the outside.
- First aid — a complete kit, checked once a year, topped up with your household's specific medication.
The method: one step at a time
There is no need to buy everything at once. Work in stages:
- Week 1: take stock of what you already own. Most households are surprised to find half of what they need is already there.
- Week 2: close the most critical gap — almost always water.
- Following weeks: complete one pillar at a time, as your budget allows.
Keep everything in a single place the whole family knows about. A dedicated container — a bag or a crate — keeps the reserve from scattering around the house over the months.
Maintaining is progressing
A reserve you forget loses its value. Put a twice-yearly reminder in your calendar: check expiry dates, test the lamps, rotate the food through your everyday meals. Fifteen minutes twice a year is enough.
Autonomy is not a destination, it is a practice. Start small, start now — and every step makes the next one easier.
