CGIAR Climate Data Hub — Wikis

Staging and publishing area for partner-facing knowledge wikis from the CGIAR Climate Data Hub community.

Live site: https://cgiar-climate-data-hub.github.io/wikis/

What this is

This repo hosts methodology and reference wikis from the CGIAR Climate Action Climate Data Hub — partner-facing content that sits between the primary scientific literature and the day-to-day climate-rationale tools the Data Hub publishes. Each wiki explains why a given tool makes the methodological choices it does, written for the national and regional partners who need to defend those choices in proposals, NAPs, and scientific reviews.

The first wiki here grew out of work on the AAA Adaptation Atlas's Build a Climate Rationale notebook — specifically, the need to give a defensible answer to which CMIP6 climate-model ensembles to use for each African region. More wikis will follow as the Data Hub commissions further reference material and as partner institutions contribute.

Each wiki is plain Markdown with Astro Starlight frontmatter. The site is built and deployed to GitHub Pages on every push to main via the workflow at .github/workflows/deploy.yml.

Quick start (local development)

npm install                    # install Astro, Starlight, and sharp (image pipeline)
npm run dev                    # local dev server at http://localhost:4321/wikis/
npm run build                  # produce a static build in dist/
npm run preview                # preview the static build locally

Adding content
