“…In northeastern England, Lord (2015) studied brownfield sites to grow willow, miscanthus, reed canarygrass, and switchgrass amended with green-waste compost and found that reed canarygrass yielded from 4 to 7 Mg ha −1 , which was greater than willow or miscanthus yields, suggesting that, in some brownfields, cool-season grasses may yield more than WSGs.

Marginal lands are candidates for growing dedicated energy crops such as perennial warm-season grasses (WSGs) and short-rotation woody crops (SrWCs), but actual field data on ecosystem services have not been widely discussed. This review (i) discusses potential marginal lands studied for energy crop production, (ii) considers the impacts of energy crops on ecosystem services, and (iii) underlines research needs. Some marginal or degraded lands studied for energy crops include highly erodible, flood-prone, compacted, saline, acid, contaminated, or sandy soils, reclaimed minesoils, urban marginal sites, and abandoned or degraded croplands. Field data are few but indicate that ecosystem services vary with the type of marginal land, management (i.e., fertilizer or amendment rates), and perennial species. M arginal lands are candidates for growing dedicated bioenergy crops, such as perennial WSGs and SRWCs, to reduce competition for land between energy and food production. Marginal lands can be defined as soils that have physical and chemical problems or are uncultivated or adversely affected by climatic conditions. The potential of marginal lands for growing WSGs and SRWCs as biofuel has received increased attention in recent years. Several questions remain, however, about which and how to grow dedicated energy crops on marginal lands, how dedicated energy crops will perform on different types of marginal lands, and whether these sites can produce abundant biomass while maintaining or improving ecosystem services.Many have used models to address the above questions and estimate the global and regional potential of marginal lands for cellulosic biomass production. These modeling studies have suggested that marginal lands offer a large potential for producing dedicated bioenergy crops while sequestering soil C, reducing net greenhouse gas emissions, and improving water quality (Davis et al., 2010;Gelfand et Humberto Blanco-Canqui* Core Ideas• Dedicated bioenergy crops can enhance ecosystem services in marginal lands.• Ecosystem services vary with the type of marginal land.• More field data are needed about the performance of energy crops on marginal lands.

“…This species has no particular requirements regarding soil type and many authors (Athar et al, 2009;Banuelos et al, 2013) believe that this plant species is moderately tolerant to salt stress and can be grown on soils with higher salt contents. Therefore, it is often referred to as the crop of marginal lands (Smith et al, 2013). However, the tolerance of oilseed rape to salinity depends on many factors, primarily on cultivars and stages of development.…”

This work was aimed to investigate the effect of salt (NaCl) stress on three oilseed rape (Brassica napus L.) cultivars: 'Banacanka', 'Jasna' and 'Kata'. The following parameters were determined: antioxidant enzymes superoxide dismutase (SOD) and guaiacol peroxidase (GPX), reduced glutathione (GSH) quantity, lipid peroxidation (LP) intensity, radical-scavenging capacity (DPPH-RSC), hydroxyl radical scavenging (• OH radicals) and ferric reducing antioxidant power (FRAP). Seed viability was determined using the standard laboratory test for germination as well as the seed accelerated aging test measuring the germination, shoot and root length. The plants were subjected to three salt treatments: 0, 100, 150 and 200 mmol dm -3 NaCl for 7 days. All three cultivars responded with an increase of lipid peroxidation in seedlings and with a decrease of GPX activity. 'Banacanka' was found to be the most vulnerable cultivar, with an increase of 237% of LP intensity in comparison to the control at the highest NaCl concentration. The induction of the SOD activity was observed for all three cultivars by different NaCl concentrations. The antioxidant capacity measured by FRAP, DPPH-RSC and• OH radicals was also induced, especially FRAP at the highest concentration in the cultivar 'Jasna' (by 282%). Germination, shoot and root length decreased for all investigated cultivars. Our results showed that cultivar 'Jasna' is the most adapted to salt stress because of the highest SOD activity and accumulation of antioxidants. Furthermore, this research suggests that some of the antioxidant parameters can be useful biochemical markers for the selection of oilseed rape tolerant cultivars under the conditions of salinity.

It is well known that most of these plants can accumulate pollutants by any of the phytoremediation process (Fig.…”

Environmental decontamination is an integral part of sustainable development. In recent years there has been growing interest in using plants for decontamination. On the other hand, water, soil and air are increasingly contaminated. Large amounts of toxic waste have been dispersed in thousands of contaminated sites spread all over the globe. These pollutants belong to two main classes: inorganic and organic. The challenge is to develop innovative and costeffective solutions to decontaminate polluted environment. Phytoremediation is emerging as an invaluable tool for environmental cleanup. Various strategies are being applied to reduce the accumulation of toxic metals in plants. Cultivation of edible crops in contaminated soils is a subject of human health concern if the contaminant concentration in the edible parts of crops plant exceed the permissible level. In such cases non-food crop production viz. value chain and value additions appears profitable. In this review: (1) the contamination due to industrial effluents in peri urban region of greater Hyderabad, and (2) the strategies to use contaminated soil and water for raising phytoremediation crops, and generation of value products. Crops and products include medicinal and aromatic plants, ornamental plants, biofuels, tree crops, fiber crops, dyes, and plants for carbon sequestration.
