Summary: The study found significant positive relationships between above-ground and below-ground mangrove carbon stocks in China, with the best fitting equation determined to be BGC = 1.58 * AGC + 81.06 (Mg/ha, R-2 = 0.62, p < 0.01, n = 122). Linear relationships between above- and below-ground carbon stocks vary for mangrove forests of different types and locations, from different geographical regions in China to other countries worldwide. The positive relationship discovered can aid in more accurate assessments of mangrove blue carbon stocks at regional or global scales.

Summary: This study investigates the potential of using unmanned aerial vehicles (UAV) and machine learning approaches to estimate oat biomass. The results show that vegetation indices derived from UAV images were significantly correlated with dry biomass in some locations. However, there were inconsistencies in accuracy across different locations. Future studies should consider using multi-year spectral data and texture features to improve estimation accuracy.

Summary: This study assessed two contrasting peatland sites in the Philippines to evaluate the impact of disturbances on carbon dynamics. The disturbed site showed significantly lower aboveground biomass and carbon content compared to the undisturbed site. Both sites exhibited an increasing trend of soil carbon content with depth. Additionally, the disturbed site had a higher soil carbon emission rate compared to the undisturbed site.

Summary: Restoration practices in marginal lands are crucial for global sustainability, with nature-based solutions playing a key role in improving soil health and biodiversity. Inoculants, especially fungal ones, have been shown to significantly enhance plant growth, soil enzyme activities, and soil carbon stock, providing a promising option for eco-restoration and carbon sequestration to achieve UN Sustainable Development Goals and food security.

Summary: Blue carbon ecosystems, such as mangroves and salt marshes, store large amounts of carbon in both plant biomass and soils. However, quantifying the specific carbon stocks in these ecosystems is time-consuming. This study used field data and published information to create spatial models of carbon stocks in mangroves and salt marshes in Southwest Florida. The results showed significant variability in carbon stocks, with lower latitude regions having higher soil carbon density and aboveground and belowground carbon stocks. The stability of these ecosystems and their carbon storage capacity are vulnerable to climate change, sea-level rise, hydrologic changes, and episodic disturbances.

Summary: This study assessed the net Delta AGB derived from four global multi-date AGB maps over the past decade. The comparison between LiDAR data and maps showed reasonable agreement, while the comparisons using NFI only had some agreements at smaller aggregation levels. Disagreement between maps is still large in key forest regions. The results suggest that the AGB assessed from current maps can be biased and any use of the estimates should consider this.

Summary: This article discusses the application of statistical research in the quantification of above-ground biomass (AGB) changes. In order to accurately map AGB changes and provide assistance for tackling climate change and monitoring policies, attention to spatial characteristics and advanced statistical methods are needed. The current techniques used in mapping and validating AGB maps lack consideration of spatial nature, so spatial cross-validation and modeling techniques that capture spatial characteristics should be employed, along with improved uncertainty estimation methods.

Summary: This study aims to develop a UAV-based vertically growing crop above-ground biomass (AGB) model to improve the difficulties in measuring biomass stored in vertical organs using optical remote sensing. The results indicate that the UAV-based VGC-AGB model (R-2 = 0.92-0.93, RMSE = 68.82-75.15 g/m(2)) is superior to the statistical regression model based on remote sensing spectral indices and CSMs (R-2 = 0.77, RMSE = 134.94 g/m(2)).

Summary: This study proposes a method for spatializing carbon emissions based on nighttime light remote sensing and municipal electricity social sensing. By integrating nighttime light and municipal electricity consumption data, the economics-energy comprehensive index (EECI) is introduced. Carbon emissions are then spatialized at a fine scale using nighttime light, municipal electricity consumption, and EECI. The geographic detector model is applied to identify factors influencing carbon emissions. The results demonstrate the accuracy of combining remote sensing and social sensing data in depicting carbon emissions.

Summary: Mangrove forests play a crucial role in protecting communities from storms and supporting fisheries. The study reveals a shift in the association between economic growth and mangrove forests, from negative impact to enabling expansion. Furthermore, community forestry is found to promote mangrove expansion, while conversion to agriculture and aquaculture results in high loss.

Summary: The ability of vegetated coastal ecosystems to store high rates of blue carbon over millennial time scales has attracted the interest of policy makers. Singapore serves as a case study to examine the generation of urban blue carbon knowledge, how it changes with urban development, and its integration into urban planning and policy. The findings suggest that coastal ecosystems can be successfully managed along urban coastlines and provide insights for blue carbon science and management in other rapidly urbanizing areas.

Summary: Mangroves are facing threats from anthropogenic activities and climate change, particularly rising salinity levels. A study conducted in the Bangladesh Sundarbans examined how increasing salinity affects forest structure, functions, and productivity. The results showed that higher salinity impedes forest growth, reduces soil nutrients, and alters the dominance of plant species. The study also highlighted the negative impact of salinity on functional variables and the importance of nutrient availability and leaf area index in maintaining the resilience of less salt-tolerant species.

Summary: This study analyzed the inequity in urban nature's contributions to people, and found that socially and economically vulnerable residents often have reduced access to the benefits of urban ecosystems. By using spatial analysis and indicators, priority regions for future investments in green infrastructure can be identified to address the inequities in urban nature's contributions. The case study of Christchurch in New Zealand provides valuable insights on how to address these inequities in future redevelopment.

Summary: Trade-offs and synergies between ecosystem services are central to land-use conflicts, but a comprehensive conceptual framework for understanding and analyzing these associations is lacking. In this study, the authors propose the ecosystem service niche as an integrative conceptual framework, inspired by species ecological niche theory. The ecosystem service niche combines socio-environmental variables and direct interactions to determine the provision of an ecosystem service. The authors also demonstrate the potential transfer of quantitative tools from species ecological niche research to improve modeling of ecosystem services.
