“…The planting material of improved varieties of these grasses was collected from CSIR‐Central Institute of Medicinal and Aromatic Plants (http://www.cimap.res.in), Lucknow, Uttar Pradesh, India. The steam distillation or hydro distillation method is used to isolate these compounds in the form of essential oil from leaves, stems and other plant parts (Clevenger, 1928; Ibrahim, Kainulainen, Aflatuni, Tiilikkala, & Holopainen, 2001; Verma et al, 2017). The biomass of these grasses left over after oil extraction can also be used for energy generation and agricultural use as organic fertilizers.…”

“…Restoration of degraded lands that provide economic support to poor farmers and biomass production for bioenergy generation are of great concern (https://sustainabledevelopment.un.org; Singh, Awasthi, Singh, & Tewari, 2020). In this regard, biomass production on marginal and polluted lands using diverse perennial grasses is receiving special attention from scientists and policy makers across the world (Awasthi, Singh, & Singh, 2017; Gelfand et al, 2013; Singh, 2019; Tilman, Hill, & Lehman, 2006; Tilman, Reich, & Knops, 2006; Verma, Trivedi, Gupta, & Verma, 2017; Yang, Tilman, Furey, & Lehman, 2019). A few long term studies have focused on tall perennial grasses and have reported that diverse cropping systems with low inputs are more productive than monocultures with high inputs (Awasthi, Singh, Soni, Singh, & Kalra, 2014; Cardinale et al, 2007; Carruthers et al, 2019; DeHaan, Weisberg, Tilman, & Fornara, 2010; Tilman, Hill, & Lehman, 2006).…”

This study investigates the effects of perennial grass species richness levels and consortium of three bacteria on properties of a slightly alkaline soil and on biomass production of grasses. Four species of perennial aromatic grasses namely: vetiver (Vetiveria zizanioides), lemongrass (Cymbopogon citratus), palmarosa (Cymbopogon martinii), and citronella (Cymbopogon winterianus) were planted in all possible combinations at one, two, three, and four species richness levels in a randomized block design with three replications and two treatments, these were PGPR+ (with plant growth promoting rhizobacteria) and without (PGPR−). Species and richness level specific changes in soil physicochemical properties: electrical conductivity (EC); bulk density (BD); total soil organic carbon (TOC); available nitrogen (Nav), microbial colony forming unit (CFU); microbial biomass carbon (MBC), and enzymatic alkaline phosphatase (ALKP) and dehydrogenase activity (DHA) were observed. The highest reduction in soil pH and EC and increase in soil TOC, CFU, Nav, MBC, and enzymes activities were found at two species richness levels of vetiver and lemongrass in both PGPR+ and PGPR− plots followed by monoculture of vetiver. The highest annual total dry biomass 22.8 and 27.5 Mg ha−1 was produced by monoculture of vetiver in PGPR− and PGPR+ plots, respectively, with similar values at two species richness levels of vetiver and lemongrass in PGPR− and PGPR+ plots. The highest plant carbon was found in vetiver monoculture and two species richness levels of vetiver and lemongrass. The soil carbon sequestration potential was highest at two species mixtures of vetiver–lemongrass and lemongrass–palmarosa as well.

“…Such an approach represents an opportunity for the public to obtain economic benefits. Plant species that can provide financial returns (e.g., energy crops, cash crops, potential biochar sources, and medicinal plants) are currently being evaluated in phytomanagement studies (Pandey et al 2016;Thijs et al 2017;Venkatachalam et al 2017;Verma et al 2017). However, the relatively low economic benefits are still an obstacle for public involvement in the rehabilitation of contaminated areas.…”

“…The selection of this plant species was based on its use for producing an essential oil that is frequently used in soaps, detergents, and cosmetics. Studies have shown that the essential oils produced from plants in metal-contaminated soils are generally free of heavy metals (Zheljazkov et al 2006;Gupta et al 2013;Verma et al 2017). Agricultural wastes (or their derived products), such as oyster shell waste, citrus peel waste, and biochar, are used as soil amendments to reduce the water-soluble fraction of Cr, which has a strong relationship with soil phytotoxicity.…”

Phytoremediation of metal-contaminated soil can be an eco-friendly technology. However, relatively long cultivation times impedes its popularization on a commercial scale. This study evaluated the effectiveness of lavender plants (Lavandula dentata L.) to remediate a highly chromium (Cr)-contaminated site through a pot experiment. The lavender growing soil was mixed both with and without biochar (2.5% w/w) + oyster shell waste (2.5% w/w) and biochar (2.5% w/w) + citrus peel waste (2.5% w/w). The results indicated that Cr(VI) accounted for 19.0% to 4.7% of the total soil Cr, while Cr(III) accounted for 81.0% to 95.3%, from the beginning to the end of the cultivation. The water-soluble Cr concentration decreased from 44.6 mg/kg to 7.5 mg/kg. The biomass of the lavender growing in the contaminated soil decreased by factors in the range between 4-fold and 6-found.The addition of soil amendments significantly reduced the (potential) bioavailable Cr (p < 0.05) in the range of 2 to 3 fold, consequently improving the growth of lavender in the highly toxic soil. In addition, the soil amendments significantly reduced the Cr bioaccumulation and the translocation from the roots to the shoots. These results showed that the cultivation of lavender with suitable amendments can effectively be used for phytomanagement techniques in highly contaminated soil.

“…The nanoremediation for sustainable crop production in polluted lands should be managed in a proper way before the expansion in such polluted lands for the agricultural production (Patil et al 2016;El-Ramady et al 2017). This currently resulted from the difficulty in measuring the sustainability of crop production in such polluted lands as well as lack in evaluating techniques for the performance of phytoremediation in frame of bioeconomy (Shalaby et al 2016;Mishra et al 2017;Shivlata and Satyanarayana 2017;Verma et al 2017).…”

MANY global problems threaten our life on the Planet including climate changes, environmental pollution, food and soil security, energy crisis, etc. This environmental pollution has not only mainly serious risks and stress involving the human health and safety of the entire ecosystem but also the quantity and quality of crops productivity worldwide. Due to the great gap between the global food production and the global consumption, there is a crucial need to cultivate these contaminated lands sooner or later. Therefore, the removing of pollutants from soils and waters should be performed in frame of sustainable remediation and sustainable energy production accordingly. Depending on many factors (source and kind of pollutants, land use and the economics of water and soil resources, etc) many strategies should be addressed for the sustainable and integrated management of polluted lands. Nanoremediation is a promising strategy in controlling pollution and management. Three major applications of nanoremediation could be characterized including detection of pollution using nanosensors, prevention of pollution, purification and remediation of contamination. Further studies also concerning the impact of changing climate on the nanoremediation process in the agroecosystems should be considered. Thus, this review will focus on the evaluation of environmental nanoremediation and its strategy in polluted lands under climate changes. Using of nanotechnology in pollution control as well as the environmental pollution and its sustainable management also will be highlighted.Keywords: Environmental nanoremediation, Climate change, Pollution, Crop production, Environmental stress. IntroductionClimate changes are a great challenge facing the human kind as well as other living things. The production of crops and other agricultural features are extremely susceptible to changes in climate. So, these global changes will be caused major shifts in crop distribution due to climate changes in the future. Moreover, it has been estimated that climate changes are likely to reduce yields and/or damage crops in the 21 Removing of pollutants from soils and waters could be linked with both the sustainable remediation as well as sustainable energy production (Kovacs and Szemmelveisz 2017; Zheng and Shi 2017). Many strategies for the sustainable and integrated management of polluted lands should be addressed depending on several factors e.g., type of pollutants and their level, the purpose of land use after remediation, soil characterization and its topography, climate , cropping patterns and the availability of resources and their economics (El-Ramady et al. 2017;Saha et al. 2017a). Furthermore, a great debate concerning using of lands for crop food production (under growing global population) or energy crop production was and still for ages (Paschalidou et al. 2016). Therefore, a global and holistic strategy in facing the main three threats including hunger, lack of energy and pollution of environment as well as climate changes should be esta...
