This study attempts to analyse the relation of ecological footprint (EF) and air pollutants—CO2, N2O, SO2 and CH4—with economic growth, urbanisation, foreign direct investment and energy consumption through environmental Kuznets curve (EKC) framework by employing fixed/random effect model. It involves a panel of 55 selected countries from several income groups—high, middle and low—covering the period 1990–2018. A theoretical approach has been developed to analyse the pollution intensity of population, based on decomposition analysis coherent with application of the notion of Kaya identity. The results confirmed the existence of inverted U-shaped relationship for EF and SO2 in all types of countries. The pollutants—CO2, N2O and CH4—exhibit inverse U-shaped EKC in middle- and low-income countries. Only for high-income countries, N2O model detects the existence of U-shaped curve. The study suggests that reconsideration of some economic and environmental policies is necessary to mitigate environmental degradation issues. JEL Codes: Q54, O4, O21, Q43, Q56

Despite debates on its hiring, contract labour is a growing form of employment in India. Establishments usually maintain a workforce composition of both regular workers and contract labour for optimizing their available resources and ensuring financial prudence. However, in the process, they often get embroiled in compliance issues related to regularization and 'equal pay for equal work' in the context of contract labour. In this article, we have explored the different judicial interpretations of the Contract Labour (Regulation and Abolition) Act, 1970, on contract labour. For this, we have referred to the landmark judgements passed by the Supreme Court of India on the deployment and regularization of contract labour, and also their entitlement to equal pay for equal work. A scrutiny of these judgements directs us to advise establishments to avoid engaging contract labour in their core and perennial activities. Considering the statutory provisions and the possible legal complications, we have recommended some measures to establishments to mitigate the underlying risks in deploying contract labour alongside regular workforce in similar kinds of jobs or activities. We propose that the legislative framework grants flexibility to industries to generate employment to contract labour, without compromising on the rights of these workers.

The PGPR Serratia plymuthica 4Rx13 produces volatile metabolites that function like antibiotics and inhibit the growth of the phytopathogenic fungi (in-vitro). In presence of bacterial volatiles anti-oxidant enzymes were activated indicating the presence of reactive oxygen species (ROS) in fungal cells. Non-enzymatic lipid peroxidation suggested the disruption of fungal membrane integrity. The fungus Sclerotinia sclerotiorum produced one typical volatile called labda-8 (20),12,14-triene. The ammonia emitted by S. plymuthica 4Rx13 could inhibit fungal growth and evoke oxidative stress in fungi.
