01In brief

The short answer.

Media and Information Systems is a chapter of Society and Human Development: a specialist sub-community with its own group, editor and research agenda. Its work starts from the cornerstone topic, media and information systems. Crisis information is what people learn about a crisis through news media, platforms, messaging apps, official channels and word of mouth. A chapter becomes a platform of its own only by meeting the graduation rule.

02Canvas

From enquiry to contribution.

Canvas · from enquiry to contributionDesign, not a record
Media and Information Systems: a working group from charter to sunsetA charter sets the question and the code of conduct; members join with declared interests; a workplan produces deliverables that are reviewed and credited; the group reports and sunsets or renews. Design of the process, not a record of a run.

03Geography

People and exposure in Latin America and the Caribbean.

For media and information systems, in GCRI's spatial-intelligence reading, the map opens on population density and true-colour imagery, framed on Latin America and the Caribbean; every other NASA layer, live feed and forecast waits in the layer list.

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