中国黒竜江省の代表的な黒土農業システムにおいて、省耕起、残渣保持、被覆作物、有機物管理、統合型畜産などの気候スマート農業実践が土壌有機炭素を増加させ、侵食リスクとGHG排出強度を低減することを実証。従来の集約的管理との比較により、低炭素・土壌保全型農業の有効性を示した。
English
This study evaluates climate-smart agroecological practices in Heilongjiang Province's black-soil farming systems, showing that conservation tillage, residue retention, cover crops, organic nutrient management, and integrated crop-livestock systems significantly increase soil organic carbon, reduce erosion risk, and lower GHG emission intensity per output compared to conventional intensive management.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の農業政策では、環境保全型農業や炭素貯留が注目されているが、本論文は中国東北部の事例であり、日本の温帯農業システムへの直接適用には慎重な検討が必要。ただし、土壌炭素隔離とGHG削減の両立可能性を示す点で参考になる。
In the global GX context
This paper provides empirical evidence from a major grain-producing region in China on the effectiveness of climate-smart agricultural practices for both soil health and GHG mitigation. It contributes to the global literature on agroecological transitions and low-carbon agriculture, relevant for countries with temperate continental climates.
👥 読者別の含意
🔬研究者:The empirical dataset and methodology offer a replicable framework for assessing the combined effects of multiple practices on soil carbon and GHG intensity.
🏢実務担当者:Farmers and agricultural extension services can use the practice bundles (conservation tillage, cover crops, etc.) to improve soil health and reduce emissions while maintaining yields.
🏛政策担当者:The results support designing regional subsidies or incentives for integrated agroecological practices to achieve both climate and soil conservation goals.
📄 Abstract（原文）
Climate change, soil degradation and intensive agricultural development jointly threaten the long-term productivity of temperate farming systems. Heilongjiang Province, a key grain-producing region of China with extensive black soils, has experienced soil organic matter losses, erosion and increasing greenhouse gas emissions from rapid mechanization and input-intensive monocultures. This article evaluates how climate-smart agroecological practices can simultaneously improve soil condition and reduce greenhouse gas emission intensity in representative farming systems of Heilongjiang Province. The analysis combines multi-year plot-level measurements of soil physical properties with farm records on crop yields, fertilizer use, residue management and fuel consumption. The dataset covers representative black-soil farming systems in Heilongjiang Province and compares conventional intensive management with agroecological practice bundles. Results show that conservation tillage, residue retention, cover crops, organic nutrient management and integrated crop–livestock systems significantly increase soil organic carbon, reduce erosion risk and lower greenhouse gas emission intensity per unit of output. The findings inform regional strategies for low-carbon, soil-conserving agricultural development in temperate continental climates.
