“…These datasets underwent various preprocessing steps, including saturation correction, denoising, threshold processing, intra‐annual fusion, inter‐annual correction, and so forth. DMSP‐OLS data were further corrected to align with NPP‐VIIRS through curve fitting. Data related to the C pool, above‐ground biomass, and soil capacity were collected through field surveys (Yan et al, 2023). Statistical data about grain production, per capita food consumption, water consumption, energy consumption, tourism income, and other factors were sourced from government statistical yearbooks. Population density data were derived from the aforementioned datasets through a process described in Section 2.2.2, using a Random Forest model for inference.…”

Enhancing the understanding and management of ecosystem services (ESs) supply and demand under the influence of global change is crucial for sustaining human well‐being and promoting sustainable development. However, the comprehension of changes in ecosystem service dynamics in the face of complex human disturbances remains limited. This study focuses on four representative ESs in the northern Liaodong Bay, a typical global estuary wetland, to elucidate alterations in the supply and demand of these ESs and comprehend the impact mechanisms arising from reclamation activities. The findings reveal the following key insights: between 1993 and 2020, the supply and demand for water yield disparity became increasingly pronounced, while the equilibrium between supply and demand for carbon storage shifted from surplus to balance. In contrast, the excess supply–demand of food supply and landscape esthetics remained relatively consistent. This study delves deeper into the non‐linear relationship between reclamation activities and ESs supply–demand relationships, with each ecosystem service exhibiting distinct patterns. As reclamation intensity rises, the supply–demand ratio of ESs exhibits varying trends: food supply and carbon storage demonstrate an inverted U‐shaped relationship, water yield follows a U‐shaped pattern, and landscape esthetics progressively decline. By identifying reclamation thresholds, different management strategies should be applied to areas exceeding and falling below these thresholds, with constraints and guidance being necessary for the former and the latter, respectively. These findings advance our understanding of ESs dynamics in the context of human‐driven changes and provide practical implications for sustainable ecosystem management in coastal areas.

“…Topic I: Blue carbon plays a prominent role in ocean and climate change issues Inextricably linked to climate, the oceans play a key role in climate change mitigation and adaptation [135][136][137][138][139][140], and blue carbon plays a potential contributing or even the predominant role [11,55,[140][141][142][143][144][145][146][147][148][149][150][151]. As part of the ongoing discussions regarding the oceanclimate nexus and blue carbon, more attention is being paid to carbon cycling and storage processes in the open ocean as a potential solution to climate change [107].…”

“…Despite the fact that the drivers were not ranked based on the assessment, key respondents cited 'institutional capacities' as a major factor hindering the management of blue carbon ecosystems [252]. A crucial component of the improvement of blue carbon sinks in China's reclamation history districts was coastal management practices (the size of industry and population control, balanced fertilization techniques in reclamation areas, and maintaining adequate vegetation cover in reserves) [147]. The fundamental drivers for reducing the total blue carbon stock of the Sundarban, the world's largest contiguous mangrove forest, are recurrent tropical cyclones, soil erosion, anthropogenic pollution, and so on [253].…”

Halfway through Transforming Our World: The 2030 Agenda for Sustainable Development, only 15 percent of the goals have been reached. As a carbon storage and climate change mitigation mechanism, blue carbon is closely related to sustainable development goals and plays an important role in the global carbon cycle. In spite of its great potential, blue carbon still faces several challenges in terms of achieving the Sustainable Development Goals. Herein, this review aims to retrieve all known impacts of blue carbon on sustainable development through research published on the Web of Science from 2012 to 2023 using a sequence of bibliometric analyses. Keywords such as “blue carbon” and “sustain*” (including “sustainability”, “sustainable”, etc.) were used for article extraction. CiteSpace, a science mapping tool, was used to capture and visually present the bibliometric information in the research about blue carbon and sustainable development. Upon reviewing the existing literature, no study has concentrated on bibliometrically analyzing and visualizing studies about blue carbon and sustainable development. This study sets out to fill this gap by examining the key areas of concentration in published works on blue carbon and sustainable development from 2012 to date. Moreover, the integration of blue carbon and sustainable development may help to develop supportive policies for marine carbon sinks. Despite the valuable contribution of this study to the blue carbon and sustainable development body of knowledge, generalizations of the results must be made cautiously due to the use of a single database, which in this case is the Web of Science.

In recent years, coastal reclamation has become an important way for coastal areas to ease the contradiction between supply and demand along the land and to develop and utilize marine resources. However, large-scale coastal reclamation will change the original natural properties of the sea area and cause changes in the surrounding hydrodynamic environment. Although coastal geomorphic features have a non-negligible impact on tidal energy loss and disaster prevention, few studies have paid attention to the intrinsic connection between the complexity of coastal morphology and the rate of tidal reduction. In this study, Hangzhou Bay is selected as the research object, and a model based on the correlation between coastal geomorphic complexity and tidal energy reduction rate is constructed by using the fractal geometry theory and the quantitative evaluation method of landscape complexity, and the model is used in the assessment of the impacts of reclaimed land in Zhoushan Islands on the geomorphic complexity and tidal energy dissipation. The results of the study show that the differential tide reduction rate is highly correlated with the complexity of islands, shoreline irregularities, curved boundaries and spatial morphology. In the application of the model, it was found that the traditional planning and design of reclamation led to a dramatic change in shoreline morphology, and with the significant reduction of the number of subdimensions D and the shape index S, the differential tidal reduction rate would be reduced by more than 88%, which also poses a significant threat to coastal and downstream estuarine bay disaster prevention. Finally, based on the above analysis, effective control indexes and scientific reclamation measures are proposed to provide theoretical basis for the efficient utilization and protection of mudflats in China.
