This special issue in Ambio entitled 'Carbon sequestration and biodiversity impacts in forested ecosystems (Volume 52, issue 11, November 2023)' brings together insights and experiences from 11 studies focusing on evaluation and integration of carbon (C) and greenhouse gas (GHG) processes, and biodiversity impacts mainly in boreal forested ecosystems. The multidisciplinary approaches include integrated modelling, mass-balance studies, Earth Observation (EO) techniques, research infrastructure developments, and evaluation of policy measures and economic compensation schemes. Although the focus is on forested ecosystems due to their large C storage and sequestration potential, importance for biodiversity, and often dominating role in the landscape, some of the papers also have a landscape approach, considering also other ecosystems (agricultural, wetland, and freshwater ecosystems) and GHG emissions from anthropogenic sources. The spatial scale of the articles ranges from detailed site-specific to a European scale. Some of the articles present main findings from a large research project funded by the Academy of Finland (IBC-Carbon), and they are complemented by other studies and international articles.
Research Infrastructures can support harmonised, cross-site data collection, curation and publication. Integrating RI networks through site co-location and standardised observation methods can help answers three questions about the terrestrial carbon sink: (i) What are present and future carbon sequestration rates in northern European forests? (ii) How are these rates controlled? (iii) Why do the observed patterns exist? Bearing these in mind, among the published papers in this special issue, we would like to highlight an article 'Leveraging research infrastructure co-location to evaluate constraints on terrestrial carbon cycling in northern European forests', where we present a conceptual model for RI co-location and highlight potential insights into the terrestrial carbon sink achievable when long-term in-situ Earth observation sites participate in multiple RI networks (e.g., #icos and #eLTER). Finally, we offer recommendations to promote RI co-location.
Ambio [The year 2022 Impact factor 6.5] – A Journal of Environment and Society publishes research on the interrelationships between society and environment. Note that all the papers in this special issue are published under open access policy. Therefore, hopefully, these papers will be extensively used and referred to.
