Exploring the wide-ranging ecosystem services of riparian vegetation on a global scale

Abstract

Riparian vegetation, as an integral part of river systems, provides various socio-ecological functions by strengthening the link between aquatic and terrestrial ecosystems. They provide comprehensive ecosystem services in physical, chemical, biological and social terms, establishing a critical link between humans and the environment. This study highlights the growing importance of riverine riparian vegetation and ecosystem services through a bibliometric analysis of scientific publications between 2000 and 2023. In the 494 publications analyzed in the study, 72% regulating (water quality, erosion prevention, climate regulation) and 43% supporting (habitat provision) ecosystem services were predominantly evaluated, while provisioning and cultural services were not sufficiently addressed. In addition, although various methods such as statistical analysis, GIS and model-based approaches were used in the reviewed studies, the lack of standardized assessment methods was identified. In conclusion, this study highlights the gaps in informed decision-making and planning in riparian areas. It emphasizes that protecting, managing and restoring riparian vegetation is critical for the sustainability of water resources, biodiversity, human well-being and overall ecosystem health.
