“…Soil biodiversity and biological activity studies can be relevant to assess soil and whole ecosystem functioning because organisms influence key ecosystem processes such as primary production (Van Der Heijden et al, 2008), decomposition and nutrient cycling (Hafeez et al, 2012), soil aeration (Frouz et al, 2007), water storage (Lavelle et al, 2006), and also organic pollutant degradation (Peng et al, 2008) or protection against metal toxicity (Leyval and Joner, 2001;Amir et al, 2014). For instance, soil biota contributes to the degradation and removal of soil contaminants through natural attenuation after ecosystem disturbances in brownfields (Mulligan and Yong, 2004).…”

The intensification and subsequent closing down of industrial activities during the last century has left behind large surfaces of derelict lands. Derelict soils have low fertility, can be contaminated, and many of them remain unused. However, with the increasing demand of soil surfaces, they might be considered as a resource, for example for non-food biomass production. The study of their physico-chemical properties and of their biodiversity and biological activity may provide indications for their potential re-use. The objective of our study was to investigate the quality of six derelict soils, considering abiotic, biotic, and functional parameters. We studied (i) the soil bacteria, fungi, meso- and macro-fauna and plant communities of six different derelict soils (two from coking plants, one from a settling pond, two constructed ones made from different substrates and remediated soil, and an inert waste storage one), and (ii) their decomposition function based on the decomposer trophic network, enzyme activities, mineralization activity, and organic pollutant degradation. Biodiversity levels in these soils were high, but all biotic parameters, except the mycorrhizal colonization level, discriminated them. Multivariate analysis showed that biotic parameters co-varied more with fertility proxies than with soil contamination parameters. Similarly, functional parameters significantly co-varied with abiotic parameters. Among functional parameters, macro-decomposer proportion, enzyme activity, average mineralization capacity, and microbial polycyclic aromatic hydrocarbon degraders were useful to discriminate the soils. We assessed their quality by combining abiotic, biotic, and functional parameters: the compost-amended constructed soil displayed the highest quality, while the settling pond soil and the contaminated constructed soil displayed the lowest. Although differences among the soils were highlighted, this study shows that derelict soils may provide a biodiversity ecosystem service and are functional for decomposition.

“…Yet, a very limited number of studies concerning the response/role of soil organisms and their biodiversity in constructed Technosols have been performed and these were predominantly conducted at the laboratory scale (Pey et al 2013;Jangorzo et al 2014;Pey et al 2014). Hafeez et al (2012) were able to successfully monitor the in situ evolution of soil microbial communities and their variabilities in such ecosystems. The authors concluded that the abundance and diversity of the microbial communities were comparable with similar agricultural soils.…”

Early colonization of constructed Technosols by macro-invertebrates

Purpose Anthropogenic activities lead to soil degradation and loss of biodiversity, but also contribute to the creation of novel ecosystems. Pedological engineering aims at constructing Technosols with wastes and by-products to reclaim derelict sites and to restore physico-chemical functions. Materials and methods The biological (dynamics of soil and epigeic macroinvertebrate assemblages) and physical (chemical and physical fertility) properties have been studied in two constructed Technosols under grassland during 4 years after their implementation. Results and discussion The soils exhibited a moderate chemical fertility (high organic matter and calcium carbonate contents, low nitrogen content) and a good physical fertility that only slightly evolved over the monitored period. Macro-invertebrates have colonized these soils. This colonization was characterized by an increasing number of individuals and species over time. The diversity and abundance values fell within those quoted in the literature for similar natural soils. Epigeic invertebrates presented a succession, indirectly linked to changes in soil parameters. No succession was recorded for soil invertebrates. However, the proportion of soil detritivores, an important functional group for soil evolution, grew consistently. Questions about soil invertebrates' functional complementarity/redundancy emerge in such artificially created ecosystem. Conclusions The constructed Technosol, on which a meadow was sown and well-established after 4 years, can host numerous soil invertebrates. In addition, an increase in diversity was monitored throughout the duration of the study.

“…Economic advantages include increased tourism, reduced energy use for indoor temperature regulation, lower wastewater treatment costs, and increased property values and tax revenue (Mell et al, 2016). Due to its ability to supply a wide range of ecosystem benefits (Flores et al, 1998;Kazemi et al, 2011;Keeley et al, 2013;Lee and Maheswaran, 2011;Opdam et al, 2006;Sandström, 2002), green infrastructure has attracted significant attention in both developed (Brunner and Cozens, 2013;European Environment Agency, 2017;Davis et al, 2009;Hall, 2010; Kabisch and Haase, 2013;Lewis, 2005;Pauleit et al, 2005) and developing (Akmar et al, 2011;Byomkesh et al, 2012;Jim, 2005;Qureshi et al, 2010;Rafiee et al, 2009) countries and is now an important component of city planning around the world (Tan et al, 2013;Zhao et al, 2013;Zhou and Wang, 2011). Interest in the use of green infrastructure is likely to increase along with the ongoing expansion of cities.…”

Abstract. With the rise in urban population comes a demand for solutions to offset environmental problems caused by urbanization. Green infrastructure (GI) refers to engineered features that provide multiecological functions in urban spaces. Soils are a fundamental component of GI, playing key roles in supporting plant growth, infiltration, and biological activities that contribute to the maintenance of air and water quality. However, urban soils are often physically, chemically, or biologically unsuitable for use in GI features. Constructed Technosols (CTs), consisting of mixtures of organic and mineral waste, are man-made soils designed to meet specific requirements and have great potential for use in GI. This review covers (1) current methods to create CTs adapted for various GI designs and (2) published examples in which CTs have been used in GI. We address the main steps for building CTs, the materials and which formulae should be used to design functional CTs, and the technical constraints of using CTs for applications in parks and square lawns, tree-lined streets, green buffer for storm water management, urban farming, and reclaimed derelict land. The analysis suggests that the composition and structure of CTs should and can be adapted to available wastes and by-products and to future land use and environmental conditions. CTs have a high potential to provide multiple soil functions in diverse situations and to contribute to greening efforts in cities (and beyond) across the world.
