ウィスコンシン州のカルスト農業地域の河川を対象に、修復区間と非修復区間で河道形態とCO2・CH4拡散フラックスを比較した。洪水と修復が温室効果ガス排出に与える影響を評価し、修復が形態変化を伴わずとも排出を増加させる一方、洪水は短期的な排出増と関連することを示した。
English
This study compared geomorphic form and CO2/CH4 diffusive fluxes between a restored reach and unrestored reference reaches in karst agricultural streams in Wisconsin over multiple floods. Restoration had limited geomorphic effects but was associated with increased GHG emissions, while flooding caused short-term emission rises, highlighting persistent agricultural legacies in stream systems.

日本のGX文脈において
河川再生事業のGHG排出への影響を示す実証研究で、日本における多自然川づくりや水辺の自然再生プロジェクトの温暖化ガス評価にも示唆を与える。直接的なGX制度連動は薄いが、自然再生的対策の気候影響を議論する際の参考となる。
In the global GX context
Provides empirical evidence on how stream restoration interacts with GHG fluxes, relevant for emerging nature-related disclosure frameworks (TNFD/ISSB) and natural climate solutions accounting. Adds freshwater GHG data to the global evidence base for evaluating restoration and flood management under climate change.
👥 読者別の含意
🔬研究者:Useful for GHG-flux researchers and restoration ecologists quantifying the net climate impact of stream restoration.
🏢実務担当者:Restoration practitioners can use these findings to anticipate that restoration alone may not reduce GHG emissions, and monitoring is needed.
📄 Abstract（原文）
In agricultural landscapes, alterations in river flow and channel geometry, increased sediment and nutrient loads, and invasive species degrade lotic ecosystems and are now being exacerbated by climate change. Stream restoration efforts respond to these pressures, but important questions remain about restoration impacts in landscapes undergoing rapid hydrologic change. Examining the relationship of stream restoration and flooding to channel geomorphology and greenhouse gas (CO2, CH4) diffusive fluxes on restored and reference reaches, we hypothesized that flood flows through restored reaches would increase cross-sectional area and floodplain connectivity while decreasing soft sediment depth, and they would increase CO2 and CH4 diffusive fluxes change in response to restoration-driven changes in channel form, floodplain reconnection, and floods. Through elevation profiles, geomorphic surveys, and greenhouse gas sampling, we compared channel form and CO2 and CH4 fluxes in a reach before and after restoration to four unrestored reference reaches in two streams in Wisconsin’s Driftless Area over a period that included multiple floods. Restoration activities were constrained by flood events and did little to enhance potential floodplain reconnection, yet they were related to increased emissions of CO2 and CH4 despite limited changes in channel form; meanwhile, flooding was related to short-term increases in emissions. These results highlight that legacies of agricultural practices are continuing to impact stream systems in subtle and compounding ways, despite and maybe even because of restoration interventions.
