ポルトガルの再エネ760件を分類し、多変量クラスター分析で18の「エネルギー・土地システム」類型を特定。風力は北部で放牧・養蜂等との共立地・共治を、太陽光は南部で生産量と外部性緩和を特徴とする。大規模案件は周辺化の強い地域に立地し社会生態的対策を多く組み込む一方、小規模案件は生産性の高い土地を占める傾向があり、規模と立地のトレードオフが政策に示唆を持つ。
English
Classifying 760 Portuguese renewable projects via cluster analysis, the study identifies 18 energy-land system types. Wind in the North favors co-location and co-governance; solar in the South emphasizes output and externality mitigation. Large projects cluster in marginalized regions with more socio-ecological measures, while smaller ones occupy more productive land—revealing scale-location trade-offs with policy implications.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも再エネの地域共生・合意形成は喫緊の課題であり、FIT/FIP制度下での立地選定や地域還元の議論に、土地・社会生態的視点を組み込む参考になる。SSBJ開示とは直接連動しないが、地域ステークホルダー対応の実務示唆がある。
In the global GX context
As global disclosure frameworks (TCFD/ISSB/CSRD) increasingly demand nature and community-related disclosures, this land-system lens offers a replicable method to assess siting externalities and social license—relevant to transition finance and just-transition criteria.

📄 Abstract（原文）
Abstract. The expansion of solar and wind power creates complex "energy-land systems" defined by interactions between governance, land use, and energy production. While critical for the energy transition, utility-scale projects often face social contestation rooted in the socio-ecological marginalization of rural areas. Addressing these challenges requires a granular, nationwide understanding of renewable energy systems and their local contexts. Focusing on Portugal, we categorized 760 renewable energy projects and used multivariate cluster analysis to identify 18 energy-land system types. Deployment contexts were analysed using indicators of socio-ecological marginalization, including land degradation, energy poverty, income levels, demographic dynamics, and land prices. Our findings reveal that geography and scale are primary drivers of energy-land system diversity. Wind systems in the North favour co-location (e.g., pasture, beekeeping) and co-governance (e.g., protected areas, commons), while solar systems in the South are distinguished by production levels and externality mitigation. Furthermore, we found that large-scale projects are frequently located in highly marginalized regions and incorporate more socio-ecological measures. Conversely, smaller utility-scale projects tend to occupy more productive, less marginalized land. These patterns illustrate trade-offs between deployment strategies—such as few large projects versus several small ones—with direct implications for energy policies. To our knowledge, this study presents the first nationwide analysis of energy-land systems, providing a replicable approach for system characterization. By adopting a land-system perspective, this research supports planning decisions aimed at creating multifunctional, equitable systems that better align rural needs with the requirements of the energy transition across various scales.
