? 2022 Elsevier B.V.Characterizing the physico-chemical properties of urban soils on a large scale remains a significant challenge. The heterogeneity and difficulty of access to these soils lead to very localized studies that are difficult to transfer to a whole urban area. This heterogeneity is mainly explained by the human factor in the formation and evolution of soils, which is a major contributor to the pedogenesis in cities. Throughout their evolution, urban soils undergo contrasting human activities that modify their properties and thus determine the historical trajectories of land use. Characterizing this human pedogenesis factor seems to be an essential condition for a better understanding of the functioning of urban soils and for qualifying them on a large scale. The aim of this work is to describe this human factor by an analysis of the historical trajectories and an evaluation of their impacts on soil properties. We focus on soils in the conurbation of Paris over the last 70 years. The different historical trajectories were identified thanks to a database provided by a local land use inventory. Results show that 80% of the total surface area is affected by 21 historical trajectories. More than 60% of this area is characterized by single use trajectories showing that most of the area has not changed land use over the last 70 years. The urbanisation of agricultural land, leading to residential areas is a representative trajectory of land use described in the paper that transforms original soils into Technosols.
