Riparian ecosystems provide key ecosystem services, yet their degradation is accelerating under growing human pressures. This study performs a systematic and bibliometric assessment to identify global trends in riparian restoration, specifying three objectives: (i) analyze the temporal evolution of scientific production, (ii) evaluate geographical patterns and North–South asymmetries, and (iii) identify dominant restoration approaches and research gaps. A total of 322 documents (1984–2025) were analyzed using productivity indicators, Lotka-based authorship patterns, co-authorship networks, keyword co-occurrence, and a logistic growth model fitted to annual publication counts, combined with descriptive statistics. Annual scientific output showed a steady 4% growth, while 78.2% of studies were led by institutions in the Global North, mainly in North America (39.1%), Europe (17.8%), and Asia (18.5%), highlighting geographical biases and limited representation of tropical regions. Restoration efforts were centered on natural regeneration and tree planting, with less emphasis on cultural ecosystem services and community participation. Despite scientific advances, challenges persist in adopting adaptive and socio-ecologically grounded approaches, especially in underrepresented regions. Strengthening science–policy links, promoting interdisciplinary collaborations, and expanding community involvement are essential to enhance riparian resilience and sustainability. We call for co-creation processes that integrate traditional knowledge and position local communities as partners in restoration efforts.
