abstract = {Green infrastructure has a role to play in climate change adaptation strategies in cities. Alternative urban spaces should be designed considering new requirements in terms of urban microclimate and thermal comfort. Pervious pavements such as green parking lots can contribute to this goal through solar evaporative cooling. However, the cooling benefits of such systems remain under debate during dry and warm periods. The aim of this study was to compare experimentally the thermal behavior of different parking lot types (PLTs) with vegetated urban soil. Four parking lots were instrumented, with temperature probes buried at different depths. Underground temperatures were measured during summer 2019, and the hottest days of the period were analyzed. Results show that the less mineral used in the surface coating, the less it warms up. The temperature difference at the upper layer can reach 10 °C between mineral and non-mineral PLTs. PLTs can be grouped into three types: (i) high surface temperature during daytime and nighttime, important heat transfer toward the sublayers, and low time shift (asphalt system); (ii) high (resp. low) surface temperature during daytime (resp. nighttime), weak heat transfer toward the sublayers, and important time shift (paved stone system); and (iii) low surface temperature during daytime and nighttime, weak heat transfer toward the sublayers, and important time shift (vegetation and substrate system, wood chips system, vegetated urban soil). The results of this study underline that pervious pavements demonstrate thermal benefits under warm and dry summer conditions compared to conventional parking lot solutions. The results also indicate that the hygrothermal properties of urban materials are crucial for urban heat island mitigation.},

In the current work, the energy crop miscanthus (Miscanthus × giganteus) was grown in ex situ conditions on agricultural soils presenting a Cd, Pb and Zn contamination gradient. After 93 days of culture, shoot and root growth parameters were measured. Soils and plants were sampled as well to study the TE accumulation in miscanthus and the effects of this plant on TE mobility in soils. Results demonstrated that miscanthus growth depended more on the soils silt content rather than TE-contamination level. Moreover, soil organic carbon at T93 increased in the soils after miscanthus cultivation by 25.5–45.3%, whereas CaCl2-extractible TEs decreased due to complex rhizosphere processes driving plant mineral uptake, and organic carbon inputs into the rhizosphere. In the contaminated soils, miscanthus accumulated Cd, Pb and Zn mainly in roots (BCF in roots: Cd " Zn > Pb), while strongly reducing the transfer of these elements from soil to all organs and from roots to rhizomes, stems and leaves (average TFs: 0.01–0.06, 0.11–1.15 and 0.09–0.79 corresponding to Cd, Pb and Zn respectively). Therefore, miscanthus could be considered a TE-excluder, hence a potential candidate crop for coupling phytostabilization and biomass production on the studied Metaleurop TE-contaminated soils.},

abstract = {Miscanthus x giganteus is suggested as a good candidate for phytostabilization of metal-polluted soils. Its late harvest in winter generates large amounts of leaf litter on the soil surface. However, little is known about the mobility and the bioavailability of metals following leaf decomposition and the consequences on the succeeding culture. Ex situ artificial aging for 1, 3, and 6 months was conducted with miscanthus leaf fragments incorporated into three agricultural soils displaying a gradient concentration in Cd (0.6, 3.1 and 7.9 mg kg−1), Pb (32.0, 194.6 and 468.6 mg kg−1), and Zn (48.4, 276.3 and 490.2 mg kg−1) to simulate the leaf litter input over 20 years of miscanthus culture. We investigated the impacts on physicochemical and biological soil parameters, CaCl2-extractable metal, and their subsequent ryegrass shoot concentrations, and hence on ryegrass health. The results showed that the amended soils possessed higher pH along with greater available phosphorous and soil organic carbon values. The respiratory activity and microbial biomass carbon in the amended soils increased mainly after 1 month of aging, and decreased afterwards. Despite the higher Pb- and Zn–CaCl2 extractability in the amended soils, the phytoavailability slightly increased only in the most contaminated soils. Moreover, leaf incorporation did not affect the ryegrass biomass, photosynthetic pigment contents, nor the antioxidative enzyme activities. Conclusively, leaf incorporation induced slight variations in soil physicochemical and biological parameters, as well as metal extractability, but not to an extent that might cause a considerable threat to the subsequent culture. Nevertheless, these results are preliminary data that require confirmation by long-term in-situ experimentations as they reflect the modelization of long-term impact of leaf decomposition on soil-plant system.},

	health risks and to improve the soil quality, a study using calcium 

	phosphates (monocalcium phosphate, dicalcium phosphate and a mixture

	(microbial and fungi communities) and physiological parameters (chlorophyll 

	a and b, antocyanins, carotenoids) as well as the phytoavailability

	use of contaminated biomass from ryegrass as a source of new valorisation 

	ways instead of using it as contaminated compost by gardeners. Although 

	slight variations in pH and significant increases of assimilable 

	phosphorus after adding calcium phosphates were registered, the physiology 

	of plants and the biological parameters were statistically unchanged. 

	The germination of the ryegrass seeds was favoured with calcium phosphates 

	regardless the contamination level of the studied soils. No clear

	the physicochemical parameters of soils, their contamination level 

	and the composition of fungal communities. Indeed, for one of the 

	soils studied, calcium could limit the transport of nutrients, causing 

	an increase in fungi to promote again the transfer of nutrients. 

	Surprisingly, the phytoavailability of Pb increased in the most contaminated 

	soil after adding dicalcium phosphate and the mixture of phosphates

	amended using phosphates in sustainable quantities in order to reduce 

	the environmental availability of potentially toxic inorganic elements 

	(PTEs) and to favour the availability of alkali, alkali earth and 

	micronutrients. The environmental availability of PTEs was evaluated 

	using a potential plant for revegetation of contaminated soils (ryegrass) 

	and a mixture of low molecular weight organic acids. Despite the 

	highest contamination level of B, the concentration of metals was 

	highest in the ryegrass shoots grown on A for the two harvests. These 

	results correlated well with those obtained using low molecular weight 

	organic acids for Cd, Zn and Cu, whereas this mixture failed to represent 

	the transfer of nutrients due to the presence of biological and physiological 

	mechanisms. The statistical differences between the biomass of ryegrass 

	obtained at the first and the second harvests were attributed to 

	the decrease of available potassium, implicated in the growth and 

	development of plants. Phosphates increased the ratios Zn/Cd, Zn/Pb 

	and Zn/Cu up to 176 ± 48, 38 ± 6 and 80 ± 12, respectively, and made 

	possible the reduction of the concentration of Cd and Pb in the shoots 

	of ryegrass by 22% and 25%, respectively. The concentration of Zn 

	in the shoots of ryegrass from the first and the second harvests 

	grown on soil A were in the range 1050–2000 mg kg−1, making this

	biomass production, source of raw materials or protection of humans 

	and environment (Blum, 2005). However, the soil functionality becomes 

	increasingly compromised due to contaminations caused by human activities. 

	In 2006 and in 39 countries, the European Environmental Agency inventoried 

	approximately 3 million of sites where pollutant activities occurred 

	with more than 1 .8 million potentially contaminated sites (CGDD 

	2013). In 2012, the most frequently identified contaminants were 

	metals (35 %), hydrocarbons (24 %) and polycyclic aromatic hydrocarbons 

	(11 %). Until recently, the most common remediation technique was 

	the excavation of contaminated soil and its disposal as landfill. 

	However, this kind of method is considered inappropriate because 

	it generates considerable disturbances, is expensive and economically 

	unfeasible on a large scale . Thus, other remediation techniques 

	(ex and in situ) have been developed to overcome these disadvantages 

	. Among them, a technique consists in adding inorganic or organic

	(Waterlot et al., 2017; Lahori et al., 2017; Oustrière et al., 2017). 

	The goal of the present work consists in evaluating the ability of

The different experimental strategies were plots planted with a tree mix or with a single tree species coupled or not with the use of fly-ashes as an amendment to limit metals mobility in soil. The breakdown of poplar litter on the four plots was monitored during 10 months. In parallel, colonization of litter bags by functional groups of mesofauna (Collembola and Acari) was followed. Two mesh sized litter-bags were used to allow distinguishing microbial and mesofaunal actions	on the litter breakdown. We observed the breakdown of litter in four 

studied plots. Litter breakdown occurred faster in 3 mm litter bags than 250 µm ones during summer demonstrating the importance of mesofauna. Mixed plantation allowed faster litter breakdown than mono-specific plantation. A higher abundance of mesofauna and/or better abiotic conditions (moisture, shading…) could explain this result. Regarding litter breakdown and mesofauna, no significant difference was observed between the amended plots and those subjected to soil phytomanagement.	However, communities of the studied area are disturbed since a low abundance of detritivores was observed. This could explain also the slower litter breakdown than expected in our study. To conclude, 

among the phytomanagement methods tested, mixed plantations could provide a benefit for the restoration of degraded soils. By contrast, the use of fly-ashes does not seem to have any effect on the functionality	of ecosystem neither on the litter breakdown process nor on the abundance of mesofauna.},

	used and the application of some levers was analyzed. Some problems 

	without solutions were identified, such as the control of bio-aggressors 

	in canned peas, weeding in onion and modulation of thresholds regarding 

	populations of auxiliaries. Results showed a lower performance of 

	IFT50 conditions (reduced by 50% in the use of phytosanitary products 

	at the cropping system scale) that varies depending on the considered 

	crop and year. However, the performances obtained are encouraging 

	and can be further improved by the end of the project},
