ブラジルで風力・太陽光発電所が建設された120以上の自治体を対象に、リモートセンシングで土地利用・被覆変化（LUCC）を定量化した。カアチンガ biome の中小都市の都市拡大と、セラード biome および風力案件立地自治体の農業開発に、再エネ導入時期と相関・因果関係が確認された。連邦州や経済的地位といった区分では有意な応答は見られず、地域の生態脆弱性と社会経済を組み込んだボトムアップ型計画の必要性を指摘する。
English
Using remote sensing, this study quantifies land use and land cover change (LUCC) in over 120 Brazilian municipalities hosting wind and solar plants, before and after deployment. It finds statistically significant correlation and causality between urban expansion in small/medium Caatinga municipalities and agricultural development in the Cerrado and wind-host municipalities, linked to renewable deployment timelines. State and economic-status groupings showed no significant response, underscoring the need for bottom-up planning that incorporates local ecological and socio-economic realities.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では再エネ拡大と地域土地利用（林地開発・農地転用・景観・住民合意）の両立がGX推進上の争点となっており、自治体スケールでの影響評価手法は国内の導入計画・環境アセス議論に示唆を与える。ただし対象はブラジルのbiomeであり、制度・土地所有の文脈は異なる。
In the global GX context
Globally, this contributes to the growing evidence base on the socio-environmental externalities of utility-scale renewables, relevant to CSRD/ISSB-adjacent nature and land-use disclosure and to just-transition safeguards in transition finance. It argues that administrative or economic proxies are insufficient for assessing local impacts, supporting site-level, biome-aware sustainability assessment.

📄 Abstract（原文）
Abstract In the last decade Brazil's energy sector has been moved from an exclusively hydroelectric and thermal mix to incorporate large-scale production of wind and solar photovoltaic energy. This energy transition is synchronised with the global imperative to reduce greenhouse gas emissions. However, the installation of large-scale wind and solar power plants has led to land use and land cover changes (LUCC) that require more detailed evaluation at the municipal scale. This work uses remote sensing data to examine LUCC in more than 120 Brazilian municipalities where wind and solar power plants have been built. The LUCC were quantified, both before and after the deployment of these plants, to determine landscape changes over time. The results reveal statistically significant correlation and causality between urban expansion in small and medium-sized municipalities within the Caatinga biome and agricultural development both in the Cerrado biome and in municipalities hosting wind projects, all linked to the timeline of renewable energy deployment. Others municipalities grouping criteria, as federative states and economic status did not show significant statistical response when analysing renewable development and municipal LUCC. These findings offer valuable insights for informing future regional planning and land use policies for balancing national energy goals with local socio-environmental sustainability. Our results point towards a critical need for bottom-up planning approaches that genuinely incorporate local ecological vulnerabilities and socio-economic realities, rather than relying solely on broad administrative or economic metrics, to ensure that renewable energy expansion genuinely supports, rather than compromises, regional sustainability goals.
