Disaster resilience
Disaster resilience is the capacity of people, institutions and systems to reduce risk, prepare, respond and recover stronger. It rests on knowledge, practice and trained people as much as on infrastructure. The Global Centre for Risk and Innovation (GCRI) supports risk reduction, readiness, recovery and competence with evidence, exercises and learning. Response stays with authorities and emergency services. Part of global challenges.

Resilience runs before, during and after a shock.
- 01
Risk reduction
Understanding hazard, exposure and vulnerability, and reducing them through planning, design and nature-based measures.
- 02
Readiness
Plans, warning systems, trained teams and exercises. GCRI's early warning capability work supports authorized agencies.
- 03
Recovery
Restoring services and livelihoods in an order that respects dependencies, and avoiding rebuilding the same risk.
- 04
Competence
People who know what to do, retained through learning and practice rather than lost between events.

The Sendai Framework vocabulary and the measures countries report against.
The Sendai Framework for Disaster Risk Reduction 2015-2030 sets seven global targets, monitored through 38 indicators that countries report in the Sendai Framework Monitor. The midterm review political declaration adopted by the UN General Assembly in 2023 asked for better disaggregated data, attention to systemic risk and faster progress on early warning.
| Term | Meaning (UNDRR, 2017) | How it is reported |
|---|---|---|
| Disaster risk reduction | Preventing new risk, reducing existing risk and managing residual risk | Existence and implementation of national and local strategies (Sendai target E) |
| Resilience | The ability of a system exposed to hazards to resist, absorb, accommodate, adapt to, transform and recover in a timely and efficient manner | No single unit; service restoration time in days and the share of functions maintained are common proxies |
| Direct economic loss | Monetary value of total or partial destruction of physical assets in the affected area | Currency of the reporting year, related to gross domestic product (Sendai target C) |
| Critical infrastructure damage and service disruption | Damage to health, education and other critical facilities and interruption of basic services | Counts of facilities damaged and service disruptions (Sendai target D) |
| Build back better | Using recovery to reduce future risk through physical, social and environmental measures | Recovery frameworks and post-disaster needs assessments |
Model disaster resilience as a system. Run the cascade.
Assembled from the Nexus Standards area profile Disaster risk reduction: the hazards it names, the systems and sectors that carry the loss, the controls that dampen it and the data that observe it. Choose the components, pick an initiating hazard and step through the cascade. The Map view places the run on an example geography with open data. Every coupling weight is a stated assumption you can change. A teaching model, not a forecast, an assessment or a certification.

The practices that decide how fast services come back.
| Practice | What it involves | Evidence of whether it works |
|---|---|---|
| Risk-informed land use and building codes | Keeping new exposure out of floodplains and fault zones; enforcing structural standards | Losses in code-compliant against non-compliant stock after events; enforcement records |
| Business and service continuity | Planned operation of essential services during disruption, under ISO 22301 or equivalent | Exercise results, recovery time objectives met in real events |
| Incident coordination | Common command structures and information flows (ISO 22320; INSARAG for urban search and rescue) | After-action reviews that record what worked and what did not |
| Humanitarian minimum standards | Water, sanitation, food, shelter and health standards in response (Sphere Handbook, 2018) | Monitoring against the standards' indicators |
| Recovery sequencing | Restoring interdependent services in an order that respects their dependencies | Restoration curves for power, water, telecoms and transport after past events |
The evidence base is uneven. Losses avoided are hard to observe: the disaster that did not happen leaves no record. Cost-benefit studies of preparedness rely on models and counterfactuals, and report results as estimates with their assumptions.
Research and capability for preparedness, never response.
GCRI studies multi-hazard and dependency risk, designs and evaluates exercises with independent evaluators, and helps national teams build competence that survives staff turnover. Response, incident command and authority warnings belong to emergency services and civil protection agencies; GCRI deploys no teams and is not an emergency service. Field work sits with the Disaster Resilience and Recovery platform, in development.
After-action findings and recovery evidence are designed for the Country Quarterly series (the third-quarter stress-test edition) and the Labs Evidence series. Exercise records would carry verification evidence under the proposed NS-11 of the Nexus Standards.
- Post-event restoration timelines for a service, with source and date.
- An after-action review a public body is willing to publish.
- Local knowledge of how a community recovered, shared with consent.
Evidence, exercises and learning.
What the risk is
Multi-hazard and dependency studies, published with methods and uncertainty.
Testing plans safely
Controlled exercises with independent evaluators. Simulated warnings never reach live audiences.
Keeping competence
Supervised learning and after-action records, through learning and courses.
Support for preparedness is not emergency response.
Nexus is not an emergency service. It does not dispatch, command incidents or issue authority warnings. Domain response teams within the National Working Groups support preparedness, observation, mapping, exercises and learning, and their interest, qualification, readiness and activation are distinct states.
In immediate danger, contact your local emergency services and follow the instructions of your authorities.
Platforms, fields and counterparts.
Field work is organized through the Disaster Resilience and Recovery platform, in development, and the disaster and crisis field gateway. The Global Risk Forum (GRF) examines disaster and crisis governance, and The Global Risk Alliance (GRA) examines disaster risk finance. See also climate and hazards.
