Marine protected areas (MPAs) are effective tools for preserving marine organisms and ecosystems against the background of climate change and intense human activities. Community participation is a helpful management approach for MPAs and has received substantial attention from researchers worldwide. To identify the research status of the field of community participation in MPAs, we reviewed 391 papers from the Web of Science with bibliometric methods and VOSviewer. The results showed that the number of publications continued to grow from 1994 to 2022, with the USA producing the most publications followed by Australia. Environmental science was the major thematic area. Studies have concentrated on community-based marine resource management, the participation mode of communities, and participatory planning and monitoring. In addition, we summarized the experience and lessons of community participation to illustrate the role of community involvement in constructing and managing MPAs. Finally, the outlook for future research was presented based on the analysis above. We recommend promoting cross-disciplinary cooperation and combining quantitative and qualitative methods to support this research. Meanwhile, it is critical to further study the specific path of community participation and fully utilize local knowledge to supplement scientific data. The current study provided an overview of publication characteristics, research trends, and primary research methods in studies of community participation in MPAs. The results will help to find ways to mitigate conflicts between MPAs and communities. We hope that our study promotes their coordinated and sustainable development and contributes to marine biodiversity conservation and human well-being.

Climate change poses substantial threats to natural ecosystems and human livelihoods, particularly in coastal regions, by intensifying coastal erosion. This process leads to land loss, infrastructure damage, and habitat destruction while amplifying challenges such as sea-level rise, flooding, desertification, and salinization. In Vietnam’s Red River Delta (RRD), the dynamic interplay between erosion and accretion presents a highly complex challenge, necessitating effective risk assessment and management to safeguard communities and resources. Using the principles of natural disaster risk assessment and comprehensive analysis, this study develops a coastal erosion risk assessment framework incorporating hazard, exposure, and vulnerability dimensions. The framework integrates 17 indicators, including human activities, socioeconomic factors, shoreline type, and vegetation cover, with indicator weights determined through expert evaluation and the analytic hierarchy process. The application of this framework reveals that coastal erosion risk in the RRD is relatively high, with greater risk concentrated in the central and northern segments of the coastline compared to the flanking areas. This framework offers valuable insights for coastal erosion prevention, mitigation strategies, and the optimization of coastal spatial planning. The application of coastal erosion risk assessment methods provides a relatively complete foundation for developing comprehensive prevention and adaptation solutions in the future. Through the system of parameters and corresponding weights, it provides an overview of potential responses to future impacts while identifying current high-risk zones specifically and accurately, thereby assessing the importance of each parameter on that impact. Based on specific analysis of assessment results, a reasonable resource use and management policy can be developed to minimize related natural disasters. Therefore, two main groups of solutions proposed under the “Protection—Adaptation” strategy are proposed to prevent natural disasters, minimize risks and sustainably develop the coastal area of the RRD.
