中国南西部の丘陵省を対象に、耕作放棄地の食料生産と炭素貯留のトレードオフを空間適性評価とパレート最適化で定量化した研究。単一目的管理では両適性の重複率が69.1%に達し機会費用が大きいが、空間優先順位付けと集約管理の組み合わせで食料ポテンシャル125.0%、炭素ポテンシャル51.6%を耕作放棄地内で増やせることを示した。食料主導・炭素主導・相乗のゾーニングが有効と提言する。
English
This study quantifies trade-offs between food production and carbon sequestration on abandoned cropland in a hilly province of Southwest China using spatial suitability assessment and Pareto optimization. Dual-suitability overlap reached 69.1%, creating high opportunity costs under single-objective management, but combining spatial prioritization with intensified management raised food and carbon potential by 125.0% and 51.6% respectively without expanding beyond abandoned cropland. It recommends spatially differentiated zoning into food-dominant, carbon-dominant, and synergistic zones.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも耕作放棄地・中山間地域の再活用は地域脱炭素や農林業のGX課題と重なる。ただし本論文は中国の事例研究であり、日本のSSBJ開示や企業実務への直接的示唆は限定的で、土地利用型気候緩和策の方法論的参考として位置づけられる。
In the global GX context
Adds to global scholarship on land-based climate mitigation and nature-based solutions relevant to SDG 2/13 alignment and emerging biodiversity/land-use disclosure discussions. Its Pareto-based spatial prioritization offers a transferable method for jurisdictions balancing food security and carbon targets, though it does not engage TCFD/ISSB disclosure frameworks directly.

📄 Abstract（原文）
Abstract Abandoned cropland is a crucial strategic reserve to reconcile food security (SDG 2) and climate mitigation (SDG 13). However, maximizing these co‐benefits in ecologically fragile hilly regions is constrained by intense spatial competition between food and carbon. In this study, we proposed a spatial decision‐making framework that integrates suitability assessment and Pareto optimization to quantify trade‐offs and identify synergistic pathways in a typical hilly province of Southwest China. The results showed that although the remaining abandoned cropland had substantial potential for either food (4.0 × 10 11 kcal yr −1 ) or carbon (1.38 × 10 6 t CO 2 yr −1 ), the dual‐suitability overlap rate reached 69.1%, leading to high opportunity costs under single‐objective management. Crucially, scenario simulations and Pareto analysis identified Pareto‐efficient compromise solutions for balancing regional benefits. When spatial prioritization was combined with intensified management, food and carbon potentials could be increased by 125.0% and 51.6%, respectively, without expanding beyond abandoned cropland. These findings highlight that governing abandoned cropland in complex terrain requires spatially differentiated zoning that distinguishes food‐dominant, carbon‐dominant, and synergistic management zones to achieve regional synergistic gains.
