ハザードの分野

Node Definition 標準
大気と気象atmo Hazards that live in the air column: storms, winds, precipitation extremes, thermal extremes, airborne particles and large-scale circulation anomalies.
水系water Hazards of fresh and salt water: floods, water deficit, sea-level and wave hazards, ocean-state extremes and water-quality degradation.
氷と雪cryo Hazards of the frozen Earth: snowpack and avalanche, glacier and permafrost change, floating ice.
固体地球geo Hazards of the crust and ground: fault shaking, eruptions, slope failure, ground deformation and surface erosion.
宇宙と地球近傍space Hazards that arrive from or act in space: solar-terrestrial storms, impacts and orbital debris.
陸域と生態系eco Hazards of the living land and sea surface: vegetation fire, forest stress, land degradation, biodiversity loss and climate-state shifts.
プラネタリー・バウンダリーと地球システムの転換点planet Hazards of the Earth system as a whole: transgression of the boundaries that keep the planet in a stable state, tipping of large climate, ice, ocean and biome components, carbon-cycle feedbacks, and rare deep-time and cosmic catastrophes.
汚染と有害物質poll Harmful substances in air, water, soil and food, toxic releases, ionising radiation and waste-containment failures.
健康とバイオセキュリティhealth Disease and biological harm to people, animals and plants, grouped by transmission route, plus systemic biological risks, chronic and mental-health burdens, drug resistance and the failure of health systems.
建造システムinfra Failure and accident hazards of structures, energy, water, digital and space-service networks, mobility, food systems, cities, ageing assets and industrial plants.
情報とサイバー・フィジカル・システムcyber Compromise or failure of information systems, including attacks that reach physical processes, identity and trust services, systemic cyber events and platforms everything else depends on.
フロンティア技術と指数関数的技術tech Hazards that arise from frontier and exponential technologies: artificial intelligence, biotechnology, advanced materials, quantum, neurotechnology, autonomy, climate intervention, space systems, digital concentration, advanced manufacturing and energy-transition technology.
社会、紛争、経済soc Violence, geopolitical and nuclear confrontation, conflict-induced harm, humanitarian crises, governance and cohesion failure, crime, demographic and labour transitions, macro-fiscal and financial-system shocks, and loss of heritage.
システミック事象と複合事象sys Events defined by interaction rather than by one process: supply-chain disruption, cascading failure, compound multi-hazard events and the structural fragility (concentration, coupling, polycrisis) that lets them spread.
02ハザード標準

Hazard Standard contexts (the six anchor streams, global risks and the nexus)

03ハザード標準

risk classes (global, catastrophic, existential, emerging, planetary, exponential, frontier technology)

Node Definition 標準
Global riskglobal A hazard is global when its occurrence, its consequences or its causal chain cross national borders and act at continental or planetary scale, so that no single country can fully assess, prevent or absorb it.
壊滅的リスクcatastrophic A hazard is catastrophic when at least one plausible scenario for it would cause global catastrophe: a very large loss of life, the crippling of global systems, or a civilisational setback that would take generations to recover from.
Existential riskexistential A hazard is existential when a plausible scenario for it would cause human extinction or a permanent, unrecoverable collapse of humanity’s long-term potential.
Emerging riskemerging A hazard is emerging when it is new, or is changing fast in nature, scale, likelihood or reach, and the evidence base for assessing it is still thin or immature.
Planetary riskplanetary A hazard is planetary when it concerns the stability of an Earth-system process: it pressures a planetary boundary, or it is, or directly drives, a tipping element whose change of state would alter the Earth system as a whole.
Exponential riskexponential A hazard is exponential when its growth or diffusion is self-accelerating, through compounding technology capability, contagion, network effects or reinforcing feedback, so that its scale can outrun linear planning and response.
Frontier technology riskfrontier-tech A hazard is frontier-tech when it arises from frontier or fast-advancing technology, through accident, misuse, unintended system behaviour or structural effects of its deployment.
