トルコの半乾燥地域で3年間の圃場試験を実施。センターピボット灌溉はスプリンクラー灌溉と比較し、サイレージ用トウモロコシの乾物収量を1.48%増加、エネルギー効率を16.89%向上、投入資材由来のカーボンフットプリントを22.22%削減した。水不足フットプリントは灌溉技術よりも灌溉水量と地域係数に依存した。これらの結果は灌溉計画と資源利用評価に資する。
English
This three-year field study in semi-arid Turkey compared center pivot and sprinkler irrigation for silage maize. Center pivot increased dry matter yield by 1.48%, energy use efficiency by 16.89%, and reduced input-related carbon footprint by 22.22%, while water scarcity footprint was more dependent on irrigation volume than technology. Findings provide field-based evidence for irrigation planning and resource-use assessment.

👥 読者別の含意
🔬研究者:Provides comparative field data on energy and carbon impacts of irrigation technologies for sustainable agriculture research.
🏢実務担当者:Farmers can use these findings to select irrigation systems that improve energy efficiency and reduce carbon footprint, though water savings may not be automatic.
🏛政策担当者:Policymakers should consider promoting center pivot irrigation in semi-arid regions for energy and carbon benefits, while water policies must address irrigation volume separately.
📄 Abstract（原文）
ABSTRACT Efficient use of water and energy resources is increasingly important for sustaining agricultural production under growing food demand and climate change pressures. This study evaluated the effects of irrigation technology on energy performance, input-related carbon footprint, and water scarcity footprint in irrigated silage maize production. Field-based data were collected over three consecutive growing seasons (2022–2024) from a large commercial farm in Ankara Province, Central Anatolia, Türkiye, where silage maize was produced under sprinkler and center pivot irrigation systems. Energy performance was quantified using an input–output energy analysis framework, input-related carbon footprint was estimated using emission factors associated with agricultural inputs and field operations, and water scarcity footprint was assessed using the AWARE characterization factor for Türkiye. Based on three-year mean values, center pivot irrigation increased dry matter yield by 1.48%, energy use efficiency by 16.89%, energy productivity by 16.88%, and net energy by 3.27%, while reducing specific energy by 14.38% compared with sprinkler irrigation. The input-related carbon footprint per unit of dry matter yield decreased by 22.22% under center pivot irrigation. In contrast, the mean water scarcity footprint was identical between the two systems, and its pattern varied by year: sprinkler irrigation showed lower values in 2022 and 2023, whereas center pivot irrigation showed a lower value in 2024. Overall, center pivot irrigation improved energy performance and reduced input-related carbon footprint under the evaluated commercial farm conditions, while water scarcity footprint was mainly governed by irrigation water volume and the regional AWARE factor rather than irrigation technology alone. These findings provide field-based evidence for irrigation planning and resource-use assessment in semi-arid silage maize production systems.
