日本語

本研究は、オーストリアの8つの多機能地上設置型太陽光発電（GMPV）施設を対象に、専門家インタビューと文献レビュー、現地調査を通じて、多機能土地利用の可能性を評価した。既存の土地等価比（LER）では複雑な土地利用システムを捉えきれないとし、新たに「多機能土地利用効果（MLUE）」手法を開発した。生態学的な配慮と複数土地利用の統合により、GMPVはエネルギー転換と生物多様性保全を両立できることを示した。

English

This study evaluates multifunctional ground-mounted photovoltaic (GMPV) systems through expert interviews, literature review, and field inspections of eight installations in Austria. It finds the Land Equivalent Ratio (LER) insufficient and introduces a novel Multi Land Use Effectiveness (MLUE) method for comprehensive assessment. Results show that ecologically integrated GMPV can support both energy transition and biodiversity conservation, offering a practical planning tool.

📝 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に伴い、農地や里山での太陽光発電と生物多様性保全の両立が課題となっている。本手法は、日本の農地ソーラーや環境アセスメントにおける土地利用評価に応用可能であり、地域共生型の再エネ導入政策に示唆を与える。

In the global GX context

Globally, as solar deployment accelerates, land-use conflicts with biodiversity are a growing concern. This study's MLUE method offers a more comprehensive framework than LER for assessing multifunctional land use, relevant to international sustainability reporting and land-use planning. It supports the integration of biodiversity considerations into renewable energy projects, aligning with global frameworks like the EU's Nature Restoration Law.

📄 Abstract（原文）

<title>Abstract</title> <p>Background The expansion of ground-mounted photovoltaic (GMPV) systems raises critical questions regarding sustainable land use and biodiversity conservation. As solar energy deployment accelerates, potential land-use conflicts emerge, including ecological disturbances during the construction phase, restricted wildlife movement due to fencing, and shading effects that alter habitat conditions. This study draws on expert interviews with project developers, a comprehensive literature review, and field inspections of eight multifunctional GMPV installations across Austria. It aims to assess the potential of multifunctional land use and to evaluate existing quantification approaches. Results The findings reveal that the commonly applied Land Equivalent Ratio (LER) is insufficient to adequately capture the complexity of multiple land-use systems in the context of GMPV. Therefore, this study develops and introduces a novel approach, the Multi Land Use Effectiveness (MLUE) method, which enables a more comprehensive assessment of land-use efficiency and ecological integration. Results indicate that, when guided by ecological foresight and the integration of multiple land uses, GMPV systems can contribute to the energy transition while simultaneously enhancing biodiversity. Conclusions The proposed MLUE approach provides a more comprehensive framework for evaluating multifunctional land-use systems than existing methods. It highlights the potential of ecologically integrated GMPV systems to reconcile renewable energy generation with biodiversity conservation and offers a practical tool to support sustainable planning and decision-making for future photovoltaic developments.</p>
