Evidence synthesis, integrity, reproducibility, grading and corrections
Research, evidence and the science-policy interface
Research, evidence and the science-policy interface covers how knowledge about risk is produced, reviewed, recorded and published so that it can be trusted, reused and corrected, and how it reaches decisions.

- Countries (Natural Earth 1:110m) The 13 countries with any vertex inside the box, as published at 1:110m with their name, ISO3 code and the Natural Earth population estimate. Made with Natural Earth (public domain), version 5.1.2 bundled at build time. read 2026-10-17. Estimate: Boundaries as published imply no position on any territory; the population figure is the Natural Earth estimate carried in the file, not a census count.
- First-level divisions, geoBoundaries gbOpen with a licence gate per boundary First-level divisions of the countries whose API record passes the licence gate in your browser, for the institutional reach view; a refused licence leaves the country without divisions and says why. geoBoundaries (Runfola et al. 2020, www.geoboundaries.org) and, per country, the boundary's own source and licence as the API record states them (Ethiopia ADM1: Open Africa, Code for Ethiopia, CC BY 4.0). Live: this page requests www.geoboundaries.org when the layer is opened; the data date is printed with it. Estimate: Boundaries as published imply no position on any territory. The gate reads each record's boundaryLicense before any geometry is requested; one request per country per page view.
- Natural events, NASA EONET live Open natural events (storms, fires, floods, volcanoes) of the last twenty days inside the box, with their category and source. NASA Earth Observatory Natural Event Tracker (EONET); each event keeps its original source link; no NASA endorsement implied. Live: this page requests eonet.gsfc.nasa.gov when the layer is opened; the data date is printed with it. Estimate: Event metadata curated by NASA from the named sources; not a warning.
Why this place: A region of about 2,300 by 2,500 kilometres where regional bodies (IGAD, the African Union, the East African Community, the Nile Basin Initiative) overlap with shared-water diplomacy on the Nile, drought and flood alerts, displacement and conflict, so institutional mandates, foresight and cross-border policy can be taught on the same globe. The twin is globe-scale rather than terrain-scale: it draws countries and first-level divisions as published, with the disclaimer that boundaries imply no position on any territory. Data quality: Natural Earth is bundled and public domain, geoBoundaries publishes each division with its own licence (Ethiopia ADM1 is CC BY 4.0 from Open Africa and Code for Ethiopia), NASA EONET events are live and open, and the INFORM Risk Index is published per country by the Joint Research Centre of the European Commission. It connects to the Risk governance and institutions, Diplomacy, cooperation and the global commons, Climate and nature governance, Conflict, fragility and security and foresight disciplines and to the convening and policy context pages of the ecosystem sites.

The boundaries, names and designations shown do not imply any judgement on the legal status of any territory, or any endorsement or acceptance of such boundaries. Countries: Natural Earth (public domain).

04The subject
The subject, methods and measures and debates and bodies
The field and its scope
For researchers, evidence synthesists, science advisers and the analysts who use their work, who need to judge how knowledge about risk is produced, graded, corrected and brought to decisions.
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
From a prior to a published claim: why a significant finding is often false, and what that does to advice
The probability that a published positive finding is true depends on the prior odds that the hypothesis was true, the study's power and its false-positive rate; low priors and low power make most significant results wrong, which is why evidence grading reads the body of evidence rather than a single paper.

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 research, evidence and the science-policy interface?
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.
