気候変動緩和シナリオではバイオエネルギーが多く使われるが、アグリボルタイクス（営農型太陽光発電）はより高い土地利用効率で電力を生み出す。モデル分析により、バイオエネルギーをアグリボルタイクスに置き換えると、必要な土地は30分の1になり、自然土地が1億600万ha増え、窒素肥料と灌漑水の使用も削減されることを示した。政策でアグリボルタイクスを促進すれば、エネルギー供給と食料生産、自然保護のトレードオフを減らせる。
English
Climate mitigation scenarios often rely on bioenergy, but agrivoltaics can generate electricity with higher land use efficiency. Modeling shows replacing bioenergy with agrivoltaics requires 30 times less land, preserving 106 Mha of natural land, and reducing nitrogen fertilizer and irrigation water use by 2060. Policies promoting agrivoltaics could reduce trade-offs between energy, food, and nature.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では再生可能エネルギー導入拡大が進むが、農地との競合が課題。アグリボルタイクスは農地を維持しながら発電できるため、日本の農地保全と再エネ導入の両立に寄与する可能性がある。また、食料安全保障と気候政策の連携という観点からも示唆に富む。
In the global GX context
Globally, agrivoltaics offer a solution to land-use conflicts between energy and food production. This study provides quantitative evidence that agrivoltaics can outperform bioenergy in land efficiency, informing climate policy and renewable energy strategies. It highlights the potential for agrivoltaics to contribute to sustainable development goals.

📄 Abstract（原文）
Climate change mitigation scenarios often include a substantial bioenergy component, raising concerns about the land use impacts of large-scale energy crop production. However, agrivoltaic systems have the potential to generate electricity with a higher land use efficiency than bioenergy by integrating photovoltaic panels into agricultural land. Here, we model the global land system to explore the land use impacts of energy crops, agrivoltaics, and photovoltaics under a 1.5 °C climate change mitigation scenario. Bioenergy demand in the bioenergy scenario increases almost six-fold from 2020 to 2060. Replacing all bioenergy with agrivoltaics requires 30 times less land, leading to 106 Mha more natural land cover, 52 Mt. less nitrogen fertiliser applied, and 305 km 3 less irrigation water withdrawn per year by 2060. Similar but smaller reductions in land use are achieved with standard photovoltaic systems. Our findings suggest that future net cropland expansion can be avoided by prioritising agrivoltaic and photovoltaic systems over bioenergy. Policies that incentivise the adoption of agrivoltaics could increase global land use efficiency, reducing the trade-offs between energy supply, food production, and nature protection.
