ギリシャの小麦畑1385区画を対象に、LCAとDEAを組み合わせて環境負荷と技術効率を評価。炭素フットプリントは2030～3110 kg CO2e/haで、過剰な窒素施肥が主因。DEAにより多くの農場で技術的非効率が判明し、窒素管理が環境・経済改善の鍵と示唆。
English
This study integrates LCA and DEA to assess the carbon and environmental footprint of rainfed wheat in Northern Greece, using data from 1385 fields. Carbon footprint ranged from 2030 to 3110 kg CO2e/ha, with excess nitrogen fertilization identified as the main driver of emissions and inefficiency. The findings highlight nitrogen management as a key leverage point for improving both environmental and technical performance, supporting spatially differentiated agricultural policies.

📄 Abstract（原文）
Rainfed wheat covers much of the semi-arid Mediterranean, yet its environmental cost is rarely measured at the field scale where management decisions are made. This study assesses the carbon and environmental footprint of rainfed wheat in the Mygdonia Basin, Northern Greece, drawing on a primary dataset of 1385 fields (~976 ha). Life Cycle Assessment (LCA) was coupled with Data Envelopment Analysis (DEA) to link environmental performance with technical efficiency. Carbon footprint ranged from 2030 to 3110 kg CO2e ha−1, revealing pronounced spatial variability across management systems. Excess nitrogen fertilization emerged as the principal driver of greenhouse gas emissions, acidification, and eutrophication in lowland systems. High-altitude systems showed lower impacts per hectare, an advantage partly offset by higher terrestrial ecotoxicity from increased machinery use. DEA revealed widespread technical inefficiency, most fields scoring between 0.70 and 0.90, with input slacks tracing this to excess nitrogen and seed. The convergence of LCA and DEA findings identifies nitrogen management as the key leverage point for improving environmental and technical performance without compromising productivity. The findings support spatially differentiated interventions under the Common Agricultural Policy, promoting precision nutrient management and conservation-oriented practices to strengthen the resilience of Mediterranean agroecosystems.
