Nitrogen deposition drives soil carbon pools accumulation and reduces greenhouse gas emissions in forests, but undermines bamboo soil carbon sinks

日本語

窒素沈着が森林と竹林の土壌炭素動態に与える影響を調査。森林では炭素蓄積を促進しGHG排出を削減するが、竹林では炭素シンクを損なうことを発見。炭素管理や気候政策への示唆を含む。

English

This study investigates the effects of nitrogen deposition on soil carbon pools and greenhouse gas emissions in forests and bamboo ecosystems. It finds that nitrogen deposition enhances carbon accumulation and reduces emissions in forests, but undermines carbon sinks in bamboo soils, with implications for carbon management and climate policy.

日本のGX文脈において

日本では森林と竹林が広く分布し、竹の侵略性が問題となっている。本研究成果は、日本の森林・竹林管理や炭素勘定に直接的な示唆を与え、特に竹林の炭素吸収源評価の見直しに寄与する。

In the global GX context

Globally, nitrogen deposition is a key driver of ecosystem carbon cycling. This paper provides novel evidence that bamboo carbon sinks are vulnerable to nitrogen deposition, challenging assumptions in global carbon accounting and highlighting the need for differentiated land-use policies.
