NEWS: CTrees researchers have produced the most detailed and accurate map of live carbon for the forests of #Gabon, measuring carbon density in every hectare of forest across the #CongoBasin country. Published in Environmental Research Letters last month, the study was led by Le Bienfaiteur Sagang, a postdoctoral researcher at UCLA’s Institute of the Environment and Sustainability and research scientist at CTrees. 🔹 Read a press release: https://lnkd.in/g7Muthfg 🔹 See the paper: https://lnkd.in/gB_58i67 Accurate measurements of biomass carbon are critical for Gabon’s efforts to fund its efforts to protect forests through carbon markets. To date, scientists in Gabon have used conventional field inventory approaches, taking measurements from a few hundred field plots to generate estimates of forest biomass across the country. But ground-based approaches are inherently limited by the availability of plot data and the cost of intensive field campaigns. The new approach detailed in the study combined satellite and ground measurements with state-of-the-art machine learning techniques to produce a wall-to-wall map for the year 2020. Results: 🔸 4 billion tons of live carbon was stored in Gabon’s forests in 2020. 🔸 The country’s managed forests had a live carbon density that was 20 percent higher on average than its unmanaged ones. 🔸 Logging concessions cover about 64% of Gabon’s area and contain 68% of the country’s total live carbon. 🔸 The map is highly accurate, with an estimated nationwide average carbon density <1% different from reference datasets available over the country. 🔸The map outperforms all global biomass datasets in resolution and accuracy, suggesting carbon maps produced at the national level can be readily integrated in the country's reporting commitments to UNFCCC. “Our results show the importance of integrating in-situ datasets into large-scale carbon maps,” said Sagang. “With this approach, we built the most accurate living carbon estimates for every hectare of forest across Gabon. This study is an invitation to countries across the Congo Basin to develop similar efforts of mapping forest carbon.” The research was funded by the U.S. Forest Service, and involved the collaboration of Gabonese institutions including the Agence Nationale des Parcs Nationaux (ANPN), Agence Gabonaise d’Etudes et d’Observations Spatiales (AGEOS), Centre National de la Recherche Scientifique et Technologique (CENAREST), and Ministère des Eaux, des Forêts, de la Mer, de l’Environnement (MINEF), with U.S. research partners at the UCLA Institute of the Environment and Sustainability, and NASA’s Jet Propulsion Lab.

Journal of Geophysical Research: Biogeosciences Volume 129, Issue 3 e2023JG007441 Research Article Global Forest Plantations Mapping and Biomass Carbon Estimation Hongtao Xu, Bin He, Lanlan Guo, Xing Yan, Yelu Zeng, Wenping Yuan, Ziqian Zhong, Rui Tang, Yang Yang, Huiming Liu, Yaning Chen First published: 18 March 2024 Abstract Management of forest plantations is a natural based solution to the global-scale mitigation of climate change; however, the role of carbon sequestration remains poorly understood, and this is hampered by a lack of detailed distribution on the global forest plantations. For the first time, we generated a global spatial distribution for forest plantations (GSDFP) during 2015 at a spatial resolution of 250 m using hierarchical extraction based on a machine learning algorithm taking time series of MODIS and ALOS PALSAR imagery as the source data, and finally estimates the biomass carbon stored in forest plantations. The resultant map was validated using reference samples visually interpreted, as well as reference samples collected from previous studies, and inter-compared with statistical forest plantation area and regional forest plantation maps, and the GSDFP was found to accurately represent the spatial distribution of forest plantations around the globe. Globally, forest plantations account for 7.35% (360.22 × 104 km2) of the global forest area and are estimated to contribute 4.60% (12.85 Pg C) of global forest biomass carbon. The forest plantation map and biomass carbon stock estimates will assist forest management and provide a benchmark for the estimation of the forest plantation carbon sink. In recent decades, global reforestation and afforestation practices have aroused wide concern in the effectiveness of climate change mitigation. However, the lack of spatial explicit data on forest plantations is the vital limitation with respect to the corresponding biomass carbon stock estimates. In this study, we generated the global spatial distribution of forest plantations at a spatial resolution of 250 m, and further estimated the biomass carbon stock in forest plantations. We found that forest plantations contributed less biomass carbon stock to forests than their corresponding area. Our results can provide crucial scientific information for decisions on forest management and climate change mitigation. Key Points • A global distribution of forest plantations was created using machine learning, and the biomass carbon stock in forest plantations was estimated • The proportion of plantation area in the forest (360.22 × 104 km2, 7.35%) is higher than that of biomass carbon stocks (12.85 Pg C, 4.60%) • The forest plantations map and biomass carbon stock estimates will be beneficial for natural based solutions for climate mitigation #carbonneutrality #netzero #naturebasedsolutions #nbs #carbonnetzero https://lnkd.in/gpwAHH_5

NEW STUDY: Assessing impacts of a notorious invader (common carp Cyprinus carpio) on Australia's aquatic ecosystems: Coupling abundance-impact relationships with a spatial biomass model Fanson et al. undertake a nonlinear meta-analytic approach to describe biomass-impact relationships for eight impact metrics and then integrate these relationships with a recently published spatial carp biomass model for Australia in order to quantify the ecological impacts of the carp invasion on Australian aquatic ecosystems. The meta-analysis compiled 286 abundance (biomass)-impact estimates from 41 studies, revealing both linear and nonlinear relationships across impact metrics. Validation with out-of-sample carp removal experiments showed high prediction accuracy for most metrics, though the model consistently underestimated macrophyte recovery by 10 to 35%. The study's findings indicate that carp invasion in Australia has significantly reduced macrophytes (by a median of 36%) and macroinvertebrates (31%), while increasing nitrogen levels (2%), plankton biomass (7%), phosphorus (8%), and turbidity (63%). This demonstrates the profound alteration of Australia's aquatic environments by invasive carp. The study offers the first quantitative assessment of this impact and presents a valuable tool for guiding carp management decisions.

𝐄𝐱𝐜𝐢𝐭𝐢𝐧𝐠 𝐍𝐞𝐰𝐬❗🎉 I'm thrilled to announce that my PhD research paper, titled "𝑳𝒐𝒄𝒂𝒍 𝑪𝒐𝒏𝒕𝒓𝒊𝒃𝒖𝒕𝒊𝒐𝒏 𝒐𝒇 𝑹𝒐𝒂𝒅 𝑻𝒓𝒂𝒇𝒇𝒊𝒄 𝒂𝒏𝒅 𝑹𝒆𝒔𝒊𝒅𝒆𝒏𝒕𝒊𝒂𝒍 𝑩𝒊𝒐𝒎𝒂𝒔𝒔 𝑩𝒖𝒓𝒏𝒊𝒏𝒈 𝒕𝒐 𝑩𝒍𝒂𝒄𝒌 𝑪𝒂𝒓𝒃𝒐𝒏 𝑨𝒆𝒓𝒐𝒔𝒐𝒍𝒔 – 𝑴𝒐𝒅𝒆𝒍𝒍𝒊𝒏𝒈 𝒂𝒏𝒅 𝑽𝒂𝒍𝒊𝒅𝒂𝒕𝒊𝒐𝒏", has been published in the prestigious Atmospheric Environment journal! Publishing as the first author in a journal filled with inspiring studies has been a long-held dream, and I’m beyond excited to share this achievement. 𝐖𝐡𝐚𝐭’𝐬 𝐭𝐡𝐞 𝐩𝐚𝐩𝐞𝐫 𝐚𝐛𝐨𝐮𝐭❓ Black carbon (BC) is a pollutant that poses serious risks to both human health and the environment. My research focuses on evaluating how local sources—specifically road traffic and residential biomass burning—contribute to BC pollution at an urban scale. Through an innovative high-resolution modelling approach, we captured the impact of these sources in Coimbra, Portugal, and validated the results over a six-month monitoring campaign. 𝐊𝐞𝐲 𝐟𝐢𝐧𝐝𝐢𝐧𝐠𝐬: • Road transport contributes more than 80% to BC concentrations at a traffic site. • Biomass burning becomes a significant contributor during the winter months. • At pollution hotspots, hourly BC levels could reach up to 85 μg/m3, emphasizing the need for detailed spatial and temporal analysis. • Modelling agrees with measurements of elemental carbon (EC), but underestimates optical equivalent BC. This study highlights the importance of 𝐦𝐨𝐫𝐞 𝐭𝐫𝐚𝐧𝐬𝐩𝐚𝐫𝐞𝐧𝐜𝐲 𝐢𝐧 𝐝𝐞𝐟𝐢𝐧𝐢𝐧𝐠 “𝐛𝐥𝐚𝐜𝐤 𝐜𝐚𝐫𝐛𝐨𝐧” reported by modelling to ensure comparability with measurements obtained by different techniques. A heartfelt thank you to my supervisor, Dr. Oxana Tchepel, for her unwavering guidance and support, and to the entire team involved in the ISY-AIR project. Curious to learn more?

Response of the copepod community to interannual differences in sea-ice cover and water masses in the northern BARENTS Sea - Frontiers in Marine Science: The reduction of Arctic summer sea ice due to climate change can lead to increased primary production in parts of the BARENTS Sea if sufficient nutrients are available. Changes in the timing and magnitude of primary production may have cascading consequences for the zooplankton community and ultimately for higher trophic levels. In Arctic food webs, both small and large copepods are commonly present, but may have different life history strategies and hence different responses to environmental change. We investigated how contrasting summer sea-ice cover and water masses in the northern BARENTS Sea influenced the copepod community composition and secondary production of small and large copepods along a transect from 76°N to 83°N in August 2018 and August 2019. Bulk abundance, biomass, and secondary production of the total copepod community did not differ significantly between the two years. There were however significant spatial differences in the copepod community composition and production, with declining copepod abundance from Atlantic to Arctic waters and the highest copepod biomass and production on the BARENTS Sea shelf. The boreal Calanus finmarchicus showed higher abundance, biomass, and secondary production in the year with less sea-ice cover and at locations with a clear Atlantic water signal. Significant differences in the copepod community between areas in the two years could be attributed to interannual differences in sea-ice cover and Atlantic water inflow. Small copepods contributed more to secondary production in areas with no or little sea ice and their production was positively correlated to water temperature and ciliate abundance. Large copepods contributed more to secondary production in areas with extensive sea ice and their production was positively correlated with chlorophyll a concentration. Our results show how pelagic communities might function in a future ice-free BARENTS Sea, in which the main component of the communities are smaller copepods, and the secondary production they generate is available in energetically less resource-rich portions. https://lnkd.in/eEjTYGAY

NEW STUDY: Contribution of offshore platforms and surrounding habitats to fish production in the Bass Strait, south-east Australia Birt et al. investigated the fish productivity associated with offshore oil and gas (O&G) platforms, focusing on one common fish species (butterfly perch - Caesioperca lepidoptera) and two commercial species (reef ocean perch - Helicolenus percoides; jackass morwong - Nemadactylus macropterus). The research is pertinent for informing decisions on whether to remove, partially remove, or retain these structures post-decommissioning. Using high-definition stereo-video imagery from a remotely operated vehicle (ROV), biomass and fish production were assessed around eight O&G platforms, their benthic surrounds, reference areas mirroring pre-installation conditions, and a natural 'reef' area. Results showed low biomass in the benthic surrounds of the platforms, reference locations, and the south-east reef, translating to negligible fish production for the studied species in these areas. In contrast, a total biomass of 2.85 tonnes was observed across the platforms, with an estimated total annual production of 1244 kg for the three species. Notably, about 79% of this production (984 kg/year) is considered "new" production directly attributable to the platforms. The study also found that the bottom 5 meters of the platforms, despite covering a small area, contained 41% of the total observed biomass and contributed to 46% of the total fish production. The production measures from these platforms are relatively high compared to other artificial reefs and habitats globally. The complete removal of these platforms could result in a decrease in fish biomass and productivity, including for various fishery species, in the immediate area. This highlights the significant role that O&G platforms may play in local marine ecosystems and has implications for decision-making processes regarding their future decommissioning.

Using Remote Sensing to Monitor Climate Change Part III: Tracking Changes in Vegetation & Carbon Sinks Using Satellite Remote Sensing 1. Selection of Satellite Sensors Satellite sensors used for tracking changes in vegetation & carbon sinks typically include optical sensors capable of capturing MSS or HSI imagery. Sensors such as MODIS (Terra & Aqua), Landsat, Sentinel-2, IRS (LISS-IV) & VIIRS (Suomi NPP) are commonly used. Additionally, radar sensors like ESA Sentinel-1 can penetrate cloud cover & provide information on vegetation structure. 2. Vegetation Indices & Spectral Analysis Vegetation indices, such as the NDVI or EVI, are derived from satellite imagery to quantify the density & health of vegetation cover. These indices are calculated based on the reflectance of light in specific spectral bands, primarily in the red & NIR regions of the electromagnetic spectrum. Changes in vegetation indices over time indicate changes in vegetation cover & biomass. 3. Time-Series Analysis Satellite imagery acquired over multiple time periods is used to create time-series datasets, enabling the analysis of vegetation dynamics over months, seasons, & years. Time-series analysis techniques, such as trend analysis, seasonal decomposition, & anomaly detection, are applied to satellite-derived vegetation indices to identify long-term trends, seasonal patterns, & anomalous events such as droughts or wildfires. 4. Biomass Estimation & Carbon Sequestration Satellite-derived vegetation indices are correlated with above-ground biomass, allowing for the estimation of carbon stocks in ecosystems. Models & algorithms are developed to convert vegetation indices into biomass estimates, which can then be used to quantify carbon sequestration rates & changes in carbon stocks over time. These estimates provide valuable information on the role of ecosystems as carbon sinks & their contribution to mitigating climate change 5. Mapping LULC Change Satellite remote sensing is also used to map changes in l& cover & land use that affect vegetation dynamics & carbon stocks. This includes monitoring deforestation, afforestation, agricultural expansion, & urbanization. High-resolution satellite imagery & advanced classification algorithms are employed to detect & quantify changes in land cover types 6. Validation & Uncertainty Assessment Validating satellite-derived estimates of vegetation dynamics & carbon stocks is essential for assessing their accuracy & reliability. Ground-based measurements, field surveys & ecosystem modeling are used to validate satellite observations 7. Integration with Ecosystem Models Satellite remote sensing data are integrated with ecosystem models to improve our understanding of the processes driving vegetation dynamics & carbon cycling. Coupling satellite observations with models allows for the simulation of future scenarios & the evaluation of potential impacts of climate change
