“…In this context, different types of unpaved roads (such as sunken lanes, paths, and cutting-filling of roads) have received considerable attention. Sunken lanes typically lie at least 0.5 meters below the adjacent land surface, enabling them sink sedimentladen runoff from adjacent areas, leading to sediment deposition downstream of nearby drainage ditches, streams, and reservoirs (Jing et al, 2022;Ngezahayo, 2020;Ramos-Scharron et al, 2024;Sati et al, 2022;Zglobicki et al, 2021). However, other types of unpaved roads may have less confluence capacity than sunken lanes but should not be neglected.…”

“…Scharron et al (2024) demonstrated that unpaved roads in the dry tropical zone of Puerto Rico led to 25 times increase in hillside soil erosion rates. Secondly, forests, while naturally undisturbed by human activities, face substantial disruption due to roads used for logging and forest management, making them T A B L E 2 Top five outputs by journals in road erosion research.…”

Global soil degradation due to road erosion is an escalating concern. This study employed bibliometric analysis using the Science Citation Index‐Expanded dataset to gain insights into research trends in road erosion. It covered the years 2000–2021, revealing a steady increase in annual research publications, particularly after 2018. The United States and Catena was the leading contributor and the most popular journal, respectively. The primary research areas identified by keywords and statistical analysis are the forests and arid regions in the temperate climate zone (including temperate continental climate and temperate monsoon climate) and the tropical climate zone (including tropical rainforest climate and tropical monsoon climate). Since 2012, a noticeable shift from traditional methods to emerging technologies like isotope tracing (e.g., 137Cs, 210Pb) and machine learning (e.g., random forest) was observed, indicating evolving in methodologies with changes in research scales. The study emphasized the inevitability of road erosion, highlighting the crucial role of effective road management and restoration. It proposed integrating best management practices and ecosystem restoration strategies into watershed management, combined with advanced technological approaches, to foster sustainable watershed development.
