本研究は低・中所得国における農業総要素生産性と温室効果ガス排出の関係を1993-2021年のデータで分析。人口増加と食料生産が排出の主因である一方、生産性向上は排出削減に寄与するが、その効果は所得水準や部門（作物・畜産）によって異なる。作物生産で最も効果的で、畜産では限定的。
English
This study examines the relationship between agricultural total factor productivity and farm-gate GHG emissions in low- to upper-middle-income countries from 1993-2021. It finds that population growth and food production drive emissions, while higher productivity reduces emissions, with strongest effects in low-income countries and crop systems, and weakest in livestock systems.

日本のGX文脈において
日本国内の農業政策には直接関係しないが、日本の国際協力や海外農業投資における気候変動緩和戦略の参考となる。また、SSBJや日本の気候関連開示において農業セクターの排出削減ポテンシャルを評価する際の知見を提供する。
In the global GX context
While focused on developing countries, this paper offers empirical evidence on how productivity gains can mitigate agricultural emissions without harming food security, relevant for global discussions on land-use and climate policy (e.g., IPCC, COP). It highlights sector-specific and income-sensitive mitigation strategies.

📄 Abstract（原文）
Abstract Agriculture significantly contributes to global greenhouse gas emissions while facing increasing climate risks, raising concerns about balancing mitigation and food security. Productivity improvements consistent with Climate-Smart Agriculture are often seen as a way to reconcile this trade-off, but empirical evidence on their effects across sectors and development levels remains limited. This study examines the relationship between agricultural total factor productivity and emissions across farm-gate, crop, and livestock systems in low- to upper-middle-income countries spanning 1993–2021. Results show that population growth and food production are the primary drivers of emissions, reflecting strong production scale effects. In contrast, higher agricultural total factor productivity generally reduces emissions, partially offsetting pressures from increased output. However, this effect varies by income level and sector. Mitigation benefits are strongest in low-income countries and weaken with development, likely due to diminishing efficiency gains and rebound effects. Sectorally, productivity-driven emission reductions are most robust in crop production, moderate at the aggregate farm-gate level, and weakest in livestock systems, likely due to biological constraints. Overall, agricultural productivity growth can mitigates without compromising food security, but its effectiveness depends on sectoral characteristics and stages of economic development. Sector-specific and income-sensitive mitigation strategies should therefore complement policies that promote productivity growth.
