Food systems and agriculture

Food systems risk concerns whether people can reliably obtain safe and nutritious food, from soils, water and inputs through production, storage, trade and markets to household access.

03The discipline

The field and its scope

For agronomists, food security analysts, humanitarian planners, commodity and insurance professionals who need to read a yield forecast, a price series or an IPC phase map and judge what it can bear.

04Measures

Quantities and units

05Methods

Methods and their limits

Each method is listed with what it assumes and where it fails.

06Debates

What the field debates

07Bodies and data

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.

08Simulator

Run the discipline's simulator

Food systems and agriculture's own model, as a live chart: move each parameter and read how the outputs respond.

09Maps

Maps and the globe for any place

Search any place or open the world; the layers and generators follow food systems and agriculture on the planet map, the globe and in 3D.
