Abstract

fetched live from OpenAlex

Abstract A major challenge of our time is to produce sufficient nutrient‐rich food for the ever‐growing human population with limited land resources. There is a huge gap between current yields and genetic potential in many crops, which can be narrowed by enhancing land productivity. High‐input cropping increases crop yields, but heavy fertilizer and pesticide use can lead to land degradation, increase greenhouse gas footprint, and carry significant risks for eutrophication. What efforts can be taken to ‘decouple’ land productivity and the environmental footprint? Can land productivity increase while concurrently minimizing the environmental footprint? Here, we show that an integrated systems approach can minimize the tradeoff to achieve an effective ‘decoupling’ outcome. Some key components that can be integrated into a system include (i) intensifying crop rotations to enhance carbon conversion from atmospheric CO 2 to plant biomass, (ii) diversifying cropping systems to enhance residual soil water and nutrient use and increase systems resilience, (iii) including N 2 ‐fixing pulse crops in rotations to reduce synthetic fertilizer use, (iv) improving fertilizer‐N use efficiency to lower N 2 O emissions, and (v) sequestering more carbon to the soil to potentially offset CO 2 equivalent emissions from cropping inputs. Integration of these proven cropping practices into a system creates a powerful synergy among individual components, thereby improving land productivity and systems resilience for long‐term sustainability. Relevant economic and agro‐environmental policies are needed to reinforce the adoption of a systems approach at the local farm level.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
