Urban soils exhibit a wide diversity of properties that have no equivalent in other environments but are overwhelmingly perceived as degraded by decision makers. As a result, their potential is not considered in urban planning even though they can deliver a range of ecosystem services. This paper describes a decision support tool for assessing soil...

Although recent projects and landscape architecture designs attempt to address a variety of environmental issues relating to food autonomy, cooling, and water management, it is clear that they still give little consideration to the multifunctionality of urban soils regarding biomass, the water cycle, carbon storage, and biodiversity, and their role...

La biodiversité des sols urbains et péri-urbains, bien qu’elle participe activement au fonctionnement des sols en ville et qu’elle subisse de nombreuses pressions anthropiques, reste encore peu, voire pas, prise en compte dans les plans d’aménagements urbains. Une des raisons de ce manque de considération est le peu de connaissance de cette biodive...

Le sol est une ressource non renouvelable et limitée qui assure des bienfaits essentiels à la viabilité des sociétés humaines (e.g production de denrées alimentaires, régulation du changement climatique, habitat pour la biodiversité). Mais le sol est un milieu fragile, menacé en de nombreux endroits, principalement du fait des activités humaines (e...

Dans un contexte mondial d'urbanisation croissante et d'intensification des pressions sur les ressources naturelles, la prise en compte des sols dans l'aménagement urbain devient un enjeu incontournable pour rendre les villes plus durables. Cet article se propose de préciser la définition du terme de sol urbain en décrivant la variabilité de ce qu'...

Cette étude a identifié des indicateurs et outils de diagnostic opérationnels permettant d'évaluer le fonctionnement des sols. Diverses options, parfois déjà expérimentées par des acteurs, pourraient permettre de promouvoir leur utilisation, notamment dans le cadre des baux ruraux (à clauses environnementales), des démarches RSE des filières agro-a...

In a context of biodiversity erosion (IPBES, 2019), a number of questions are currently being asked about soil biodiversity in urban areas. While the urban ecosystem integrates humans and all the disturbances they can induce, it is important to carry out a work of soil organisms’ quantification and knowledge transfer to citizens in order to increas...

Purpose Given their increasing importance, soils should be considered as valuable resources by those involved in urban planning. Indeed, soils are expected to be multifunctional in order both to ensure sustainable development of human societies and to resist major environmental issues. Through the study of planning documents, this article describes...

Le développement des aires urbaines induit une amplification des enjeux environnementaux (e.g. qualité de l’air, îlot de chaleur urbain, inondation). Pour apporter une réponse à ces défis, la fabrique urbaine intègre progressivement les fonctions assurées par les écosystèmes urbains. Cependant, cette considération semble négliger les services écosy...

The purpose of this article is to understand how collective gardens are taken into account in French urban planning. To do this, it proposes a review of the law relating to collective gardens. In this regard, it notes its lack of efficiency. Focused on allotment gardens, the law is incapable of translating realities in constant evolution. Based on...

Urban soils need to be taken into account by city managers to tackle the major urban environmental issues. As other soils in forest or agricultural environments, urban soils provide a wide range of ecosystem services. However, their contribution remains poorly assessed up to now, and as a result there is a strong lack of consideration by urban plan...

Soils, as ecosystems provide services that are also called ecosystem services. In the context of natural resources preservation, urban soils are expected to be multifunctional and to provide high level of ecosystem services (e.g. vegetation support, building support, flood control). Therefore, there is a need for urban planners to take into account...

Urban soils are a resource poorly taken into account for the conception and construction of sustainable cities (Morel et al., 2014). This can be explained by the fact that the intense human influences and the fast succession of land-uses lead to a great variety of soils on a limited surface area (compared to natural environments) and to a lack of s...

Dans les zones urbaines, les sols représentent une ressource méconnue et un enjeu essentiel car ils font l’objet de changements très rapides d’affectation et d’utilisation (e.g. activités urbaines et industrielles, espaces verts, jardinage, maraîchage et agriculture). Le redéploiement urbain sur des sites de friches urbaines et industrielles est un...
