スペイン・バレンシア地域の柑橘類農地を太陽光発電所に転用する際の土壌炭素変化をRothCモデルで評価。樹木除去で72 Mg ha−1のCO2排出、植生なしでさらに28 Mg ha−1排出、低木被覆で−226 Mg ha−1のCO2吸収となる。地域全体では最大1.2×10^6 Mg排出または2.7×10^6 Mg吸収の可能性。
English
This study evaluates soil carbon changes when converting citrus fields to solar parks in Valencia, Spain, using the RothC model. Removing trees releases 72 Mg ha−1 CO2eq, with additional 28 Mg ha−1 if left bare, but scrubland cover can achieve −226 Mg ha−1 capture. Regionally, 12,000 ha could emit up to 1.2×10^6 Mg or capture 2.7×10^6 Mg CO2.

📄 Abstract（原文）
The current trend towards decarbonization has increased the pressure towards land use change through the installation of solar parks on agricultural fields. The usefulness of RothC to model the evolution of soil carbon after the installation of the solar park has been validated in a field with historic data. The model has been applied to evaluate the impact of a large-scale modification of land use in Valencia (Spain), a mediterranean region with an ambitious plan for the installation of renewable energy. The removal of the orange trees for the installation of a solar park would generate a carbon release in CO2 eq to 72 Mg ha−1. If the soil is left vacant of vegetation, another 28 Mg ha−1 would be emitted in 30 years. By contrast, if the soil is covered by scrubland, an overall CO2 capture of −226 Mg ha−1 could be achieved, including the impact of the initial plant removal. If we consider the Valencia region, the installation of 12.000 hectares of solar parks could generate up to 1.2 × 106 Mg of CO2 emissions or capture 2.7 × 106 Mg of CO2. Also, a sensitivity analysis to evaluate the effect of the main labels has been performed, revealing that the original carbon content is the most relevant label, followed by plant input and the % of soil covered by the solar panels. The limited availability in experimental data means that this study should be considered an exploratory evaluation of the impact of including plantations in solar parks.
