Data and code for: Synergistic Management of Abandoned Cropland Mitigates Trade-offs Between Food Security and Climate Mitigation in Hilly and Mountainous Areas

This repository contains the data products, analysis code, and robustness-test outputs supporting the manuscript “Synergistic Management of Abandoned Cropland Mitigates Trade-offs Between Food Security and Climate Mitigation in Hilly and Mountainous Areas.” The archive includes: (1) Abandoned cropland.zip: processed 10 m cropland-abandonment maps and land-use maps for Sichuan Province during 2017–2023, together with the processed spatial products required to reproduce the core analyses; (2) Code.zip: scripts for data preprocessing, suitability modeling, food-production and carbon-sequestration accounting, scenario allocation, Pareto-frontier analysis, spatial prioritization, and figure generation; (3) revision_exp01_maxent_threshold.zip: MaxEnt threshold-sensitivity analysis; (4) revision_exp02_food_baseline_actual_calibrated.zip: food-potential baseline validation and yield-calibration analysis; (5) revision_exp03_rcp_food_robustness.zip: food-potential robustness analysis under alternative RCP scenarios; (6) revision_exp04_rcp_pareto_robustness.zip: Pareto-frontier robustness analysis under alternative RCP scenarios; (7) revision_exp05_threshold_pareto_robustness.zip: robustness analysis combining alternative MaxEnt thresholds and Pareto allocation; (8) revision_exp06_carbon_disturbance_risk_lowmem.zip: carbon-retention sensitivity analysis considering disturbance risk; (9) revision_exp07_synergy_zone_characteristics_rank_based_fixed.zip: synergistic-zone characterization and rank-based spatial-priority analysis; (10) revision_exp08_top30_land_sparing_robustness.zip: robustness analysis of the top-30% land-sparing estimate. All raster outputs are aligned to a common 100 m × 100 m grid. Third-party input datasets are not redistributed where their original providers retain distribution rights; their original sources and access routes are reported in Table S1 of the Supporting Information. A README file describes the archive structure, software environment, file dependencies, and workflow for reproducing the analyses.
