本研究は、フィンランドの2つの泥炭採掘跡地を対象に、植林、泥炭地再生、湿地造成、農業など複数の土地利用オプションの気候調整ポテンシャルを評価した。詳細な空間データと気候影響モデルを用いて、各オプションの温室効果ガス収支を計算し、気候調整、生態系回復、食料生産など異なる目的に沿ったシナリオの気候影響を分析した。結果は、サイト条件や所有者の選好に応じて、気候に配慮した複合的な土地利用が可能であることを示し、戦略的な堰き止めと排水によるマルチハビタット景観の創出が経済的・生態的利益をもたらす可能性を提案する。ただし、採掘後の温室効果ガスフラックスに関する知識ギャップは依然として大きい。

English

This study evaluates the climate regulation potential of post-extraction land use at two peat cutaway sites in Finland, considering afforestation, peatland restoration, wetlands, agriculture, and biomass production. Using spatial data and a climate impact model (REFUGE4), the authors calculate greenhouse gas balances for each land use and assess scenarios aligned with different objectives (climate regulation, ecological restoration, food production, timber production, biomass production). Results show that climate-wise land use combinations are feasible depending on site conditions and stakeholder preferences, and suggest that strategic damming and ditching to create a multi-habitat landscape can provide economic and ecological benefits. However, substantial knowledge gaps remain regarding greenhouse gas fluxes from post-extraction land uses.

日本のGX文脈において

フィンランドの泥炭採掘跡地を対象とした本論文は、採掘後の土地利用オプションが気候調整に与える影響を評価する手法を提供する。日本でも泥炭地や採掘跡地の管理に応用可能であり、特に気候変動緩和策としての土地利用計画に示唆を与える。

In the global GX context

This paper contributes to global understanding of peatland after-use for climate mitigation by providing a spatially explicit framework that evaluates greenhouse gas balances of different land-use options. It addresses knowledge gaps crucial for carbon accounting in land-based climate solutions and offers a methodological approach applicable to other peat-rich regions worldwide.

👥 読者別の含意

🔬研究者:This study provides a spatially explicit framework for evaluating climate impacts of different after-use options for peat extraction sites, useful for researchers in peatland ecology and land-use modeling.

🏢実務担当者:Land managers and extractive industry can use the approach to identify climate-wise after-use combinations and plan multi-habitat landscapes for economic and ecological benefits.

📄 Abstract（原文）

Mitigating climate change and halting biodiversity loss require sustainable after-use strategies for peat extraction sites. This study evaluates the climate regulation potential of post-extraction land use using two peat cutaway sites in South Ostrobothnia, Finland, as case examples. The land use portfolio examined includes afforestation (conventional and short-rotation), peatland restoration, creation of open-water wetlands, conventional agriculture, reed canary grass cultivation and paludiculture. First, we mapped all suitable areas for each land use at the two case study sites, based on detailed spatial data on surface elevation, peat thickness and subsoil characteristics. Second, we calculated the climate warming impact of each land use based on published greenhouse gas flux and biomass estimates using REFUGE4, a climate impact model. Third, we assessed the climate impact of land-use scenarios aligned with five different objectives: climate regulation, ecological restoration, food production, timber production, and peat-replacing biomass production. This allowed us to explore how landowners' preferences or policy choices may influence climate outcomes. The results suggest that various climate-wise land use combinations are feasible after peat extraction, depending on site-specific conditions and landowner and policy preferences. We propose that tailoring land use to site characteristics and using strategic damming and ditching to create a multi-habitat landscape can provide both economic and ecological benefits. However, substantial knowledge gaps remain regarding greenhouse gas fluxes from post-extraction land uses.
