“…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).…”

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.

“…In her study of the jatropha hype in Indonesia, Vel [11] warns against unintended effects of biofuel policies and discourses when they translate into a business opportunity for short-term private benefits instead of for the social and environmental goals for which the policies were originally intended. While the 'original intention' behind India's biofuel policy remains an issue of debate [88,102] there seems to be a continuing trend of discursively linking government policy with development. As Michael and Baumann [23] emphasize in their study of India within the global land grabbing discourse, and as also shown above, the Indian government has applied a strategy of exclusion of aspects and actors in the debate that oppose their own views and has strategically linked 'land acquisition' with 'development', depicting anyone who opposes the government's land acquisitions as also opposing 'development'.…”

Land Grabbing and Jatropha in India: An Analysis of ‘Hyped’ Discourse on the Subject

In the early 2000s, powerful narratives (re-)emerged around the food–fuel–land nexus, which, combined with the financial, food, and fuel crises of 2007-08, sparked new concerns about the finiteness of our resources and triggered, as well as partially justified, the then following land rush. Around the same time, a hyped debate also developed around biofuels as a potential fix to some of the global scarcity problems in which jatropha held a particularly prominent position as a new miracle crop. This study examines the concurrence of jatropha and the land grabbing hype in India, the leading promotor of the plant globally, and asks what effect the global land grab discourse had on actual jatropha investments in the country. To do so, an extensive literature review, discourse analysis, and qualitative survey were conducted, with a specific focus on jatropha investors. The study found that both hyped discourses have impacted investor decisions, but the impact varied depending on the types of company. This study adds a yet underrepresented investor perspective to the global land grabbing discourse and highlights a need to also consider the role of small and medium enterprises in land grabbing processes.

Student performance of virtual introductory physics class (calculus-based mechanics) is analyzed. A fully web-enhanced class was done synchronously. The analysis is done in two categories, averaging all mid-exams (or chapter exams) and cumulative final exams. It shows that students perform well with shorter timed mid-semester assessments (or chapter exams) than the longer timed assessments. Results were then compared with two survey questions to investigate the effect of the background knowledge of physics and calculus on their performance. It shows two interesting results, a) students with basic conceptual background knowledge of physics perform well, b) calculus knowledge does not correlate well with student performance. These findings can be used to rethink and redesign the assessments for calculus-based introductory physics classes. Also, the findings can be used to develop a supplemental support program to enhance student performance.
