“…Furthermore, the incorporation of artefacts as well as residues from human activities (e.g. traffic, industry) may cause contamination (Béchet et al, 2009;Craul, 1992;El Khalil et al, 2013;Joimel et al, 2016) in the coarse fraction and fine earth (El Khalil et al, 2008). As a consequence, the physical and chemical fertility of urban soils is often low, even if some of them are designed to provide a suitable medium for plant growth and biomass production (e.g.…”

et al.. Towards an operational methodology to optimize ecosystem services provided by urban soils. Landscape and Urban Planning, Elsevier, 2018, 176, pp.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 planning of the services they provide. Indeed, urban soils are mostly seen as a land surface (land area, two-dimensional system) and if they are characterized, it is almost exclusively for their potential contamination and their geotechnical properties. So, policy makers and planning operators rarely consider soils as a living resource, capable to fulfill essential functions. From the conclusions of previous studies, a selection of ecosystem services provided by soil and adapted to the specificity of urban context is proposed. This paper also aims at proposing the concept of the DESTISOL decision support system for urban planning projects upstream of the planning decisions, illustrated by an application example. It is based on an integrative approach linking soil quality indicators (e.g. physico-chemical and biological characteristics, fertility, pollution), soil functions and soil ecosystem services. The method leads to the semi-quantitative assessment of the level of ecosystem services that are either provided by urban soils or required to fit with the urban design.

“…The quality of a soil is defined as its ability to fulfill functions and provide ecosystem services (Morel et al, 2014). Anthropisation, which designates an effect resulting from "human activity" (El Khalil et al, 2013), is often described as the main driver of ecosystem modifications (Vitousek et al, 1997), especially for biotopes like soil. The fertility level and contamination of soils are generally considered to be two aspects of soil quality.…”

Soil quality is related to soil characteristics such as fertility and contamination. The aim of this study is to assess the effect of land use on these soil characteristics and to confirm the following anthropisation gradient: (i) forest, (ii) grassland, (iii) cultivated, (iv) orchard and vineyard, (v) urban vegetable garden, and (vi) SUITMA (urban, industrial, traffic, mining and military areas). A database comprising the characteristics of 2451 soils has been constituted. In order to compare the topsoils from six contrasting land uses, a principal components analysis (PCA) was performed on nine geochemical variables (C, N, pH, POlsen, total Cd, Cu, Ni, Pb, Zn). The first axis of the PCA is interpreted as a global increase of topsoil metallic elements along the anthropisation gradient. Axis 2 reflects the variability of fertility levels. Human activity increases the pressure on soils along the proposed gradient according to six different distribution patterns. This better knowledge of topsoil quality and its dependence on current land use should therefore help to manage and preserve the soil mantle.

“…In 1900, only 13 % of the world's population lived in the cities (Saier 2007), but by 2011, the percentage had increased to 52 % (United Nations 2013). Huge changes in the soil cover and soil processes can be observed in different cities around the world (Effland and Pouyat 1997;El Khalil et al 2013). The urban ecosystem is characterised by new types of humanmade systems resulted from degradation, destruction and/or substitution of natural systems (Stroganova et al 1998).…”
