Brazil’s National Civil Defense has advised households to prepare enough essential supplies to manage for up to 72 hours, arguing that severe weather and other disasters can temporarily cut access to water, power, communications and emergency assistance.

The guidance calls for drinking water, non-perishable food, medicines, hygiene supplies and basic equipment tailored to the number and needs of people in each home. Its water benchmark is two litres per person per day—six litres per person over three days—alongside shelf-stable foods such as canned goods, cereal bars, dried fruit and biscuits.¹

The agency’s rationale is centred on the first, difficult hours after a major incident. Rescue teams may be delayed where flooding, blocked roads or other access problems isolate communities, according to the guidance. It also recommends torches, spare batteries, portable chargers and AM/FM radios so families can receive official information during power or mobile-network disruptions.²

The advice has nevertheless generated questions about whether it signals an approaching emergency. Civil Defense’s position is explicitly different: the notice is “strictly preventive” and does not indicate an imminent crisis or a nationwide shortage.¹ Rather than asking households to respond to a particular alert, it encourages them to reduce their immediate dependence on public assistance after a disruption.

The recommended kit extends beyond food and water. Families are urged to keep regular medicines and updated prescriptions, first-aid materials, protected personal documents, and provisions for infants, older people, pets and anyone reliant on specific medical equipment. Officials also advise checking expiry dates and testing equipment periodically, treating the reserve as a maintained household safeguard rather than a one-time stockpile.²
