Climate finance and risk
Parametric Insurance
Insurance that pays out automatically when a measurable trigger — such as rainfall or wind speed — is crossed, rather than after assessed losses.
Definition
Parametric insurance is cover that pays a pre-agreed amount when a defined, independently measurable parameter — rainfall below a threshold, hurricane wind speed, earthquake magnitude — is met or exceeded, rather than compensating individually assessed damage. Payouts are fast and transparent, though payouts may not match actual losses (basis risk).

Overview
What it means
Traditional indemnity insurance is slow and costly to administer in data-poor regions; parametric schemes can deliver funds within days of a disaster. They are used for sovereign disaster risk (e. g. , regional risk pools such as the African Risk Capacity and CCRIF), for farmers through index-based crop cover, and increasingly for climate adaptation.
How it is used
Development banks, insurers and governments deploy parametric products in climate-vulnerable countries; the approach features in loss and damage and climate risk finance discussions.
Why it matters
Rapid, pre-arranged payouts can prevent disasters from becoming development reversals, making parametric insurance a key instrument for climate resilience where conventional insurance markets fail.
Review
Public comments appear only after editor acceptance. Draft comments stay in the review queue.
Reviewers choose the definition or an overview paragraph, leave a comment or replacement, and attach evidence or a source link.
Editors compare reviewer cards side by side. AI may help find agreement, conflicts, unsupported claims and possible source issues.
Only an editor-accepted synthesis changes the public page. Reviewer identities are shown only with consent and an editorial decision to attribute them.
Submitted reviews stay private until an editor decides whether to accept and attribute them.

Review board
Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.
Each person comments on the definition or overview in their own draft card, with role, evidence and suggested wording kept together.
AI can compare comments against the current text, flag conflicting claims, surface missing evidence and identify where reviewers agree.
An editor merges compatible suggestions into a draft change, checks sources, records disagreements and decides what can be published.
