Parklands dominated by tree species such as Faidherbia albida provide multiple ecosystem services in fragile regions of sub-Saharan Africa, but the persistent decline of F. albida raises concerns about the stability of agricultural systems and food security. The aim of the study is to analyze the research trend on the causes of Faidherbia albida decline, to identify the main research themes, major issues and conceptual evolutions related to F. albida decline, and to explore the gaps in knowledge of F. albida decline. The bibliometric analysis shows a general upward trend in research on the subject since 2008, with a strong contribution from South Africa. Growth factors, biotic factors, experiments and specific studies on F. albida are the main clusters linked to F. albida decline factors in scientific publications. These different clusters dealing with the factors of F. albida decline, in particular seedling mortality and excessive pruning, are less explored. The results highlight the importance of in-depth research to identify the underlying causes and develop appropriate management strategies to ensure the long-term survival of these crucial species in our ecosystems.
