  abstract = {{D}escription of the subject. {F}aidherbia albida is recognized as a promising agroforestry species. {I}n agroforestry systems, tree water use ({TWU}) dynamics is a key component of its impacts on associated crop yield and the water balance. {L}ittle is known about {F}. albida water uptake while an estimation of the ecosystem water balance is crucial in the context of climate change.{O}bjectives. {T}he aim of this study is to assess {F}. albida water use along a year and the implication of tree size, season and phenology. {M}ethod. {F}ive mature trees were selected in an agroforestry parkland in the groundnut basin near {N}iakhar village in {S}enegal to monitor sap flow. {T}ree water use ({TWU}) or ({Q}) was calculated and climate conditions, soil water content and leaf phenological phases were also continuously recorded. {R}esults. {R}esults revealed a significant {TWU} variability between rainy and dry seasons and between leaf phenological stages. {T}he maximal water use values were observed in the first part of the dry season between {D}ecember and {J}anuary, when the trees are in full leaf, with large between-tree variability, from 118 to 261 l.tree-1.d-1. {T}he {TWU} slowly decreased during the dry season and reached minimal values during the leafless phase which takes place during the rainy season.{C}onclusions. {T}he average annual water use was estimated at about 40,000 l.tree-1.year-1, i.e. 27 mm.tree-1.year-1, which represents 5.3% of 2019 annual rainfall (513 mm). {T}he significant relationship of {TWU} with leaf phenological phases ({R}2 = 0.81) supports the possibility that a simple model can estimate the tree water use.},
