Mapping and monitoring of mangrove species based on remote sensing technology play a crucial role in biodiversity conservation and management. This paper employs CiteSpace to visualize the literature and presents a comprehensive review of the researches conducted in this domain, focusing primarily on bibliometric characteristics, diverse sensors, and classification algorithms. Since the publication of the first remote sensing-based study on mangrove species classification in 2004, the number of publications in this field has exhibited a general upward trend up to 2023. China, the United States, and India lead in publishing research on mangrove species mapping, with researchers in the United States being particularly active in international collaborations. Mapping of mangrove species is predominantly concentrated on single time points and across 53 small regions, with the majority of research sites located in India and China. Existing studies have utilized various remote sensing image for mangrove species classification, including airborne hyperspectral, spaceborne visible, infrared, multispectral, hyperspectral, synthetic aperture radar (SAR), and drone-borne visible, infrared, multispectral, hyperspectral, light detection and ranging (LiDAR) data. Classification algorithm development has evolved four stages, from pixel-based methods to object-oriented approaches, progressing to approaches incorporating machine learning algorithms, and currently advancing towards ensemble learning and deep learning. Research in this field still faces several challenges in data fusion, classification algorithm enhancement, increased number of classification species, and large-scale long-term mapping. The studys findings would provide valuable guidance to researchers and practitioners in advancing and enhancing the management and conservation of mangroves

The objective of this research was to analyze the scientific production of sustainability reports, given their importance in environmental, social and governance (ESG) factors at the organizational level. Using a bibliometric analysis from 2007 to 2023 in the Scopus database, 3,812 papers were identified. The 10 most cited papers, the 10 most cited authors, the leading countries in the field, and institutional affiliations were reviewed. The main results indicate that the United States was the country with the highest contribution, followed by China and Australia. A relevant finding is the institutional affiliation of the authors, highlighting Wageningen University & Research in the Netherlands, which produced 34 papers. In conclusion, this analysis underscores the importance of integrating effective ESG practices to address global challenges, promoting long-term sustainable development.

The persistence, bioaccumulation, and toxicity of perfluorinated and polyfluoroalkyl substances (PFASs), along with their concentrations in the environment and humans, have attracted global attention. However, so far, there have been seldom reports providing a systematical review in the entire field of PFASs research. Therefore, this study summarizes 14,112 relevant publications (2005–2022) and conducts bibliometric analysis using Vosviewer and CiteSpace. The findings offer insights into global PFASs research trends, assisting scientists in establishing their research directions. Unlike traditional literature reviews, this article presents a new method for data collection and analysis that achieves quantitative visualization of the information from the past 18 years in the field of PFASs. Results show a significant increase in global PFASs publications, with China leading in publication output and the US in international collaborations. Author Kurunthachalam Kanna has the highest publication records. Document co-citation clustering and key line analysis identifies four major research areas and landmarks, while betweenness centrality analysis reveals developmental processes. Citation burst analysis finds that PFASs toxicity and monitoring have been hot areas, suggesting the need for greater attention towards the types and levels of PFASs in various environmental media and the removal processes of PFASs responsible for pollution, which may emerge as future research hotspots.
