Abstract

fetched live from OpenAlex

Are we on the verge of a fourth agricultural revolution? In this insightful analysis, Professor Guillaume Blanchet from Université de Sherbrooke examines whether we are on the verge of a fourth agricultural revolution and explores new technologies for agroecology. The first agricultural revolution is considered to have occurred sometime ten to twelve thousand years ago when humans transitioned from being hunters and gatherers to settlements focused on agriculture. The second agricultural revolution was between the 17th and 19th centuries when new technologies (such as crop rotation, drainage and plough) were developed, significantly increasing yield and productivity.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
