01In brief

The short answer.

Disaster and Crisis Governance in Nexus Universe is the platform's part in the annual programme GRF governs, through mission themes such as multi-agency crisis exercise. Themes are proposals; confirmed exercises are announced on universe.nexus, and results are published with their limits after review.

02Canvas

Scoping to review.

Canvas · scoping to reviewDesign, not a record
Annual programme contribution: an exercise from design to lessonsObjectives and a scenario are designed with the owner; injects are scripted; players respond in cells while controllers and observers watch; a hot wash and an after-action report turn observations into owned improvements. Design of the process, not a record of a run.

03Geography

Hazards now in the Caribbean.

For annual programme contribution, in GRF's situational-awareness reading, the map opens on population density, flood water and active fires, framed on the Caribbean; 3 further NASA layers wait in the list.

The interactive map needs JavaScript; the layer list and sources are below.

    Multi-agency crisis exercise

    A mission theme proposed for the annual programme.

05Key terms

Terms used on this page.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.

TermDefinition
Mission themeA subject a platform proposes for controlled testing in the annual Nexus Universe programme; a theme is a proposal until the programme confirms an exercise.
Full-scale exerciseAn operations-based exercise in which agencies deploy people and equipment in real time against a scenario.
After-action reviewA structured review of what was planned, what happened and what should change, held after an exercise or real event.
Simulation exerciseA practice, training or evaluation activity in which an emergency is described or simulated and participants respond as they would in reality, so that plans and capacities can be tested, as WHO's exercise manual describes.
06Gateway

The GRF gateway explains the programme's governance, and universe.nexus is its own site.

07Questions
