“…Agricultural land uses in the baseline can result in CO 2 emissions as tillage and other practices disturb soils resulting in decomposition of soil organic matter (IPCC 2019). Soil CO 2 emissions from baseline land uses were linked to SOC stocks in the baseline land uses (Table 4) following the approach of Hagger et al (2022). Annual SOC stock change factors (Table S3) were applied to SOC estimates for different land uses for the different climatic regions that were extracted from the Australian national SOC map (Table 4).…”

Restoration of coastal wetlands has the potential to deliver both climate change mitigation, called blue carbon, and adaptation benefits to coastal communities, as well as supporting biodiversity and providing additional ecosystem services. Valuing carbon sequestration may incentivize restoration projects; however, it requires development of rigorous methods for quantifying blue carbon sequestered during coastal wetland restoration. We describe the development of a blue carbon accounting model (BlueCAM) used within the Tidal Restoration of Blue Carbon Ecosystems Methodology Determination 2022 of the Emissions Reduction Fund (ERF), which is Australia's voluntary carbon market scheme. The new BlueCAM uses Australian data to estimate abatement from carbon and greenhouse gas sources and sinks arising from coastal wetland restoration (via tidal restoration) and aligns with the Intergovernmental Panel for Climate Change guidelines for national greenhouse gas inventories. BlueCAM includes carbon sequestered in soils and biomass and avoided emissions from alternative land uses. A conservative modeled approach was used to provide estimates of abatement (as opposed to on-ground measurements); and in doing so, this will reduce the costs associated with monitoring and verification for ERF projects and may increase participation in blue carbon projects by Australian landholders. BlueCAM encompasses multiple climate regions and plant communities and therefore may be useful to others outside Australia seeking to value blue carbon benefits from coastal wetland restoration.

“…Nevertheless, our study demonstrates that blue carbon science is a rapidly growing field and is still in a strong growth phase (as indicated by its exponential publication trajectory). Our bibliometric study showed that while past trends in the blue carbon science were more related to understanding the carbon cycling in these ecosystems, the research is transitioning to understanding the opportunity for new technologies to help estimate carbon stocks (i.e., remote sensing, machine learning models; (Costa et al 2021;Ewers Lewis et al 2020;Pham et al 2020;Sanderman et al 2018;Simard et al 2019;Young et al 2021), the role of these ecosystems as nature climate solutions through their restoration and conservation (Costa et al 2022;Hagger et al 2022;Macreadie et al 2021;Moritsch et al 2021;Wedding et al 2021), and finally, the potential changes in their distribution and carbon sequestration due to future climate conditions.…”

Abstract‘Blue carbon’ was coined over a decade ago to describe the contribution of mangroves, seagrasses, and tidal marshes to carbon drawdown in coasts and oceans, concomitantly attracting attention of policy-makers and resource managers to their potential as a natural climate solution. Here, we explore the emergence and evolution of this relatively new research field through bibliometrics approaches to investigate patterns and trends in scientific publications through time. Our aim was to understand the evolution of blue carbon science, from where we came from and where we are now. We analysed 1,729 papers from 5,763 authors. Overall, the carbon-sink capacity of these ecosystems has been recognised long before the term ‘blue carbon’ was coined; with an annual percentage growth rate of 20% y− 1. Research attention was highest for mangroves (~ 38% of publications), followed by saltmarshes (~ 22%), and seagrasses (~ 18%); while ~ 16% of the studies included two or more blue carbon ecosystems and 5% of the studies focused on other ecosystems. The citation burst analysis showed that, in the 1990s, the hot topic (i.e., fast-growing topic) was related to the overall flux and dynamics of carbon, with a recent transition to the role of coastal vegetation to climate change mitigation from 2009. The term ‘blue carbon’ became a hot topic in 2017, with the strongest citation burst between 2017 and 2020. This bibliometric study draws the patterns and trends of blue carbon science and indicate that this field is evolving through time to focus more on the blue carbon role as nature climate solutions.

“…Whales could enhance primary production through a range of processes . If such processes and the precise mechanisms involved can be established, and the mitigation contribution quantified, then additional benefits as ecosystem services be identified, they could be related to some form of 'carbon credits' (Costello et al, 2012), and the corresponding funds be used for marine ecosystem restoration (Hagger et al, 2022).…”

Frontiers is more than just an open access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers journal seriesThe Frontiers journal series is a multi-tier and interdisciplinary set of openaccess, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers journal series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to qualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers journals series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area.
