04The subject
The subject, methods and measures and debates and bodies
The field and its scope
For finance ministry, disaster management, development bank and insurance staff who need to arrange in advance how the cost of a disaster will be paid and by whom.
Quantities and units
Methods and their limits
Each method is listed with what it assumes and where it fails.
What the field debates
Bodies that set practice, and the data they publish
Bodies and standards are named so learners can find and apply their published work; the Academy teaches their use and links to the publisher, and no affiliation is implied.
05The method
Layering disaster risk: reserves for the frequent, insurance for the rare, and the cost of what is left
A government faces frequent small disaster losses and rare large ones; each layer is cheapest to finance with a different instrument, and the retention level where reserves end and insurance begins sets the yearly cost of the whole strategy.

11Questions
Questions, answers and key terms
Is study here free?
Yes. Every course and learning material of Risk Academy, led by the Nexus Consortium, is free to study, self-paced or with a cohort. Ordinary participation has no fee; paid work, internships and fellowships are separate arrangements.
What does completing a course give me?
A completion record: the course, its version, the date and what was assessed, private by default and shared by you. It stacks into discipline, department and programme achievements. A record states what was studied and assessed and does not certify competence; it is not a licence, a professional title or an employment status.
Where do the data and the places come from?
Every faculty teaches on a twin of a real place built from open data; each layer carries its provider, licence and date, and every result on the Academy states its source. Maps and figures are indicators for teaching, never an assessment of a place.
How do I take part beyond the courses in disaster risk finance?
Form a competence cell of three to seven people, study a shared pathway, take a supervised assignment in the National Working Groups, or bring a cohort from your institution. For organisations.
Key terms
Term
Risk layering
Matching financing instruments to events of different frequency and severity.
Term
Parametric trigger
A payout rule based on a measured hazard parameter rather than assessed loss.
Term
Basis risk
The mismatch between a parametric payout and the actual loss.
Term
Catastrophe bond
A security that transfers defined catastrophe risk to investors.
