     Présentation (FED) : Cet article présente certaines des conclusions d’un exercice d’évaluation scientifique collective de l’artificialisation des sols, qui a impliqué 55 experts scientifiques et qui est basé sur plus de 2500 références académiques et techniques internationales. Le but est d'étudier ce qui entre dans la définition de "terre artificialisée" et d’analyser les processus de changement d'utilisation des terres et des fonctions du sol en raison de l'urbanisation, phénomène social inévitable. Après avoir clarifié ces processus fondamentaux les auteurs examinent les instruments de politiques publiques qui, en France, visent à limiter les effets négatifs des changements d’occupation des sols, tout en permettant un développement ultérieur des activités humaines. Ils montrent que certains de ces outils sont souvent mal adaptés, ne prenant pas suffisamment en compte la diversité des utilisations du sol.

    Abstract (authors) : Jointly commissioned by the ministries responsible for the environment (MTES) and agriculture (MAA) and the public agency for the environment and energy (ADEME), the IFSTTAR (French Institute of Science and Technology for Transport, Planning and Networks) and the INRA (National Institute of Agronomic Research) have carried out a collective scientific report (ESCo) on land take that addresses its measurement, causes and consequences, as well as policies to limit its expansion or negative effects. This article presents some of the conclusions from this exercise, which involved 55 scientific experts and is based on knowledge from more than 2500 international academic and technical references. The aim here is to investigate this complex process, as well as the uses that come under the definition of ‘artificialised land’, by attempting to distinguish the processes by which land use and soil functions change as a result of urbanisation, an unavoidable social phenomenon. Only after clarifying these basic processes can we examine the public policy instruments and regulations that, in France, aim to limit land take and its negative effects whilst allowing for further development of human activities. We show that some of these tools could be effective but are often ill-adapted, in particular with regard to the variety of issues resulting from land take, which depend on the type of land cover (urban, peri-urban, rural) and on the specific uses of these areas.
