Outline of Final Research Achievements

In Mie Prefecture, large-scale solar panels were installed at 2,521 locations between 2015 and 2016, and at an additional 5,121 locations between 2016 and 2021. When solar panel installation locations overlapped with pre-FIT land cover/use, many solar panels were installed in forests during both periods. In addition, 0.39 km2 of solar panels overlapped with landslide-prone areas in 2015-2016 and 0.96 km2 in 2016-2021. When we identified effective locations for solar panel installation and overlaid the installed solar panels, we found that 30 to 40% were installed in low-priority locations.

Academic Significance and Societal Importance of the Research Achievements

中山間地域で太陽光パネルの建設ラッシュが起きる中,里山景観を保全するとともに,災害に結び付くことのない太陽光パネルの配置を行うことは,環境への負荷が少ない安心で安全なエネルギーを持続的に供給していく上で絶対的な条件である。本研究では,不適切な場所への大規模な太陽光パネルの設置が明らかとなった。本研究の成果は,立地条件を見極めて太陽光パネルの設置を行うための重要な基礎資料となる。本研究の成果を踏まえて,過疎化の進む中山間地域から環境への負荷が少ない安心で安全なエネルギーを持続的に供給していくことで,中山間地域の再生につながると考えられる。
