中国の華北平原における小麦、米、トウモロコシ生産の水・エネルギー・炭素の連関を定量化し、2018年を基準に中国の第14次五カ年計画に基づく管理シナリオを評価した。統合シナリオ（窒素肥料30%削減、効率的肥料生産、スプリンクラー灌漑、作物残渣50%還元）により、水フットプリント、エネルギー使用、GHG排出をそれぞれ4.9%、27.6%、39.2%削減できることを示した。一方、点滴灌漑単独では水は減るがエネルギーと排出が増えることを明らかにし、水保全策と炭素中立のトレードオフを指摘した。
English
This study quantifies the water-energy-carbon nexus for wheat, rice, and corn production in the North China Plain, using 2018 as baseline and evaluating management scenarios aligned with China's 14th Five-Year Plan. An integrated scenario (30% nitrogen fertilizer reduction, efficient fertilizer production, sprinkler irrigation, 50% straw return) reduces water footprint, energy use, and GHG emissions by 4.9%, 27.6%, and 39.2%, respectively. In contrast, drip irrigation alone reduces water but increases energy use and emissions, highlighting trade-offs between water-saving and carbon neutrality.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の農業分野におけるGX推進（みどりの食料システム戦略等）に示唆を与える。水・エネルギー・炭素の連関を考慮した統合的評価は、日本の農業政策や地域計画にも応用可能であり、SSBJ開示におけるScope 3排出量算定の精緻化にも寄与する。
In the global GX context
This study provides empirical evidence on the trade-offs between water-saving measures and carbon neutrality in agriculture, relevant to global discussions on sustainable agriculture and climate policy. It offers a framework for integrated assessment that can inform ISSB-aligned disclosure and transition planning in the agricultural sector.

📄 Abstract（原文）
Agricultural management influences progress towards carbon neutrality through its effects on water consumption, energy use, and greenhouse gas (GHG) emissions. However, few studies have translated policies across sectors into management scenarios and evaluated their combined consequences for the agricultural carbon neutrality. We quantified the water, energy use, and carbon nexus for wheat, rice, and corn production across the North China Plain using 2018 as a baseline scenario. We then evaluated conditional management scenarios informed by China’s 14th Five-Year Plan. The three crop production generated net emissions of 1.8 × 1010 kg C yr−1 in 2018, while cropland net ecosystem productivity offset 16.9% of GHG emissions related to crop production. Energy use was positively correlated with GHG emissions (r = 0.74, p < 0.01). The integrated scenario combining a 30% reduction in nitrogen fertilizer, more efficient nitrogen fertilizer production, sprinkler irrigation, and a 50% crop straw return rate reduced the water footprint, energy use, and GHG emissions by 4.9%, 27.6%, and 39.2%, respectively. By contrast, drip irrigation alone reduced the water footprint but increased energy use by 6.8% and GHG emissions by 12.9%. The results show that water saving measures do not necessarily improve the carbon neutrality when their energy requirements are overlooked. These findings also provide more enlightenment for local policy-makers.
