01In brief

The short answer.

Learning in Health Nexus is the set of paths through which professionals build competence in the health and biosecurity field, starting from the methods it applies, such as epidemiology and public health science as well as molecular and life sciences. Courses are listed once approved, with provider, level and terms; completing one is a learning record, not a professional licence or certification.

02Canvas

From enquiry to contribution.

Canvas · from enquiry to contributionDesign, not a record
Learning and professional development: 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

Environmental exposure in Africa.

For learning and professional development, in GCRI's spatial-intelligence reading, the map opens on population density, true-colour imagery and night lights with true colour from NASA GIBS, framed on Africa; 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.
