Nature-based solutions: a holistic approach of phytoremediation for wetland conservation and management
摘要
Wetlands contribute a significant role in supporting local ecology by providing flood mitigation, maintaining the hydrological cycle, groundwater recharge, recreational value, regulating weather patterns, and promoting ecological restoration. However, rapid urbanization and climate change have led to significant degradation of these ecosystems. This study evaluates wetland management through a nature-based solutions approach, focusing specifically on phytoremediation. The review covers the fundamentals of phytoremediation—including its literature base, processes, mechanisms, the role of plants, and influencing factors—while integrating a bibliometric analysis of 702 publications. Our analysis reveals significant growth in the field, with an average annual increase of 0.89% and a compound annual growth rate of approximately 14.65%, peaking in 2023. Key contributing countries include China and the United States, and leading authors are Afzal, M. and Abdullah. Co-citation analysis identified three distinct research clusters, with maximum citations for Kadlec (31) and Vymazal (26), reflecting diverse research foci in phytoremediation and wetland management. The study outlines several phytoremediation frameworks for wetland remediation and recommends combining diverse methods to address complex challenges. Despite the expanding body of research, many aspects of design and operation remain underexplored. Nature-based solutions provide sustainable, ecologically friendly strategies for environmental conservation and effective wetland management.
