Conditions for human survival
Relatively safer countries and regions, environments for survival, and the conditions for enduring.
By risk: countries and regions relatively better placed
These are relative assessments based on research. No place is guaranteed safe.
Overall assessment and where Japan stands
From the 2026 research review "No Place to Hide?"
Environments and preparations for survival
Four common factors raise a region's resilience whatever the disaster: geographic isolation, self-sufficiency, quality of governance, and decentralized infrastructure.
Water and food
Farmland and water sources you can rely on. Seven days of household supplies; national readiness for a halt in imports.
Energy
Decentralized power such as solar and small hydro. Systems that keep the essentials running in a blackout.
Information and communication
Radio, emergency broadcast systems, paper records: ways to get the message through when the internet is down.
Healthcare and hygiene
Local medical capacity, regular medicines, early detection of infectious disease, and stockpiled supplies.
Human connection
Neighbors who know and trust each other. Communities that help one another recover faster.
Preserving knowledge and seeds
Paper books, local libraries, handed-down skills, and insurance such as Norway's Global Seed Vault.
Four conditions for humanity to endure
The four multiply together. If any one is missing, the whole collapses.

1. Safe AI
Technology that can verify an AI's goals and behavior. Confirm safety first; expand capability second.

2. Human control
Humans take responsibility for critical decisions in nuclear, medical and infrastructure domains. Systems designed so they can be stopped.

3. A resilient society
The ability to recover from disaster: decentralization, reserves, analog backups, the capacity to think, and trust.

4. International cooperation
Even rivals cooperate on safety: common standards, verification, incident sharing, and human control of nuclear weapons.
