The potential climate feedback from destabilizing peatlands, storing large amounts of carbon, remains poorly quantified. Using the reduced-complexity Earth System Model OSCAR with an integrated peat carbon module, we found that across various overshoot pathways that temporarily exceed 1.5°C-2.5°C, northern peatlands exhibit net positive feedback, amplifying the overshoot challenge. Warming increases peatlands' net carbon uptake, but this is largely offset by higher methane emissions. We estimated that for each 1°C increase in peak warming, the positive feedback from peatlands decreases the remaining carbon budget by 37 GtCO₂ (22-48 GtCO₂). If the 1.5°C temperature target is exceeded, peatlands would increase carbon removal requirement by about 40 GtCO₂ (16-60 GtCO₂) (8.6%). Our findings highlight the importance of properly accounting for northern peatlands for estimating climate feedbacks, especially under overshoot scenarios.</p>","PeriodicalId":52366,"journal":{"name":"One Earth","volume":"8 8","pages":"None"},"PeriodicalIF":15.3,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12356699/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144876748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used data from socioeconomic, land use, and dietary surveys conducted with 460 women in both the dry and wet seasons. Our results illustrate that, compared to other uses, the use of on-farm trees for food is the most significant determinant of women's micronutrient adequacy across seasons.

This paper introduces a framework for evaluating trade-offs in land-based CDR activities following the recent United Nations Environment Assembly definition of NBS. This framework emphasizes ecosystem integrity, human rights, and sustainable development, aligning with the objectives of the three Rio Conventions, which provide a guardrail to inform pathways toward feasible and equitable implementation.

Deadwood, an often-overlooked source of biomass, exemplifies this dilemma, yet the evidence needed to enhance its management is sparse. Here, we put the role of deadwood into perspective through a literature review and comparison of estimates in managed and unmanaged forests. We demonstrate that deadwood intersects many overlapping and sometimes conflicting policies, playing a multifaceted role in the bioeconomy, biodiversity conservation, soil health, fire mitigation, bioenergy, and carbon storage. Given the increasing pressure on deadwood and the ecosystem services it provides, we argue that coherent and mutually supportive policies are needed to develop multifunctional pathways that reconcile deadwood management with biodiversity, bioenergy, and climate objectives. Therefore, we suggest that harmonized data and monitoring are essential, along with transdisciplinary collaboration, to identify trade-offs between biomass uses and values and ensure the maintenance of functional forest ecosystems.</p>","PeriodicalId":52366,"journal":{"name":"One Earth","volume":"30 1","pages":""},"PeriodicalIF":16.2,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142259434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
