Peer Review #2 of "A meta-analysis contrasting active versus passive restoration practices in dryland agricultural ecosystems (v0.1)"
Bibliographic record
Abstract
Restoration of agricultural drylands globally, here farmlands and grazing lands, is a priority for ecosystem function and biodiversity preservation.Natural areas in drylands are recognized as biodiversity hotspots and face continued human impacts.Global water shortages are driving increased agricultural land retirement providing the opportunity to reclaim some of these lands for natural habitat.We used meta-analysis to contrast different classes of dryland restoration practices.All interventions were categorized as active and passive for the analyses of efficacy in dryland agricultural ecosystems.We evaluated the impact of 19 specific restoration practices from 42 studies on soil, plant, animal, and general habitat targets across 16 countries, for a total of 1,427 independent observations.Passive vegetation restoration and grazing exclusion led to net positive restoration outcomes.Passive restoration practices were more variable and less effective than active restoration practices.Furthermore, passive soil restoration led to net negative restoration outcomes.Active restoration practices consistently led to positive outcomes for soil, plant, and habitat targets.Water supplementation was the most effective restoration practice.These findings suggest that active interventions are necessary and critical in most instances for dryland agricultural ecosystems likely because of severe anthropogenic pressures and concurrent environmental stressors -both past and present.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
