「幾何学的適地」を超えて：イタリア・エミリア＝ロマーニャ州におけるソーラーベルト、土地能力、および地上設置型太陽光発電施設

イタリア・エミリア＝ロマーニャ州を対象に、工場・商業施設周辺350mの「ソーラーベルト」が地上設置型太陽光の適地とされる制度をGISで検証した。ソーラーベルトには優良農地（土地能力分類I・II級）が相当含まれ、既存施設の圧力と潜在的な曝露は市町村単位で異なる。単純な幾何学的基準ではなく土壌評価をエネルギー計画に統合すべきと結論づける。
English
Using GIS, this study examines Emilia-Romagna's 350 m "solar belts" around industrial and commercial sites, legally designated as suitable for ground-mounted PV. It finds these belts overlap extensively with ordinary farmland and high-quality Class I–II soils, with municipal-level variation in actual vs. potential pressure. The authors argue energy planning must integrate pedological assessment rather than rely on simple geometric criteria.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも農地転用と太陽光立地の調整（営農型・農地法・地域計画）が論点であり、適地基準に土壌・土地利用評価を組み込む視点は、再エネ促進区域の設計や地域合意形成を考える国内実務者に示唆を与える。
In the global GX context
As EU and global disclosure regimes (CSRD, EU taxonomy) increasingly scrutinize land-use and biodiversity impacts of renewables, this paper shows how spatial suitability rules can conflict with soil protection—relevant to transition-planning and nature-related risk disclosure debates.

📄 Abstract（原文）
Policies aimed at accelerating the energy transition increasingly rely on simplified spatial criteria to identify suitable areas for renewable energy facilities, including ground-mounted photovoltaic (PV) plants on agricultural land. Yet these criteria often overlook soil quality, thereby fuelling the conflict between energy production and agriculture. This paper examines this issue through the case of Emilia-Romagna, Italy, focusing on the 350 m solar belts around industrial and commercial facilities, recognised as legally designated suitable areas for ground-mounted PV plants. Using GIS techniques, regulatory buffers were integrated with land-use data, land capability data, and the location of existing plants. The results show that solar belts include extensive ordinary agricultural areas, not subject to environmental or landscape constraints, and a significant share of high-quality soils belonging to classes I and II of the Land Capability Classification. Comparing actual pressure exerted by existing plants with potential exposure associated with suitable areas identifies different situations at the municipal scale. The case study shows that renewable energy deployment, unless guided by selective criteria, may increase pressure on the highest-quality agricultural soils. This points to the need to integrate pedological assessment into energy planning, moving beyond a definition of suitable areas based on simple geometric criteria.
