“…Existing Indian inventories for different pollutants or climate-forcing agents are decided on the Intended Nationally Determined Contributions (INDCs) for policy-making purposes. GHG emission inventories are part of INDCs under the national communications of the United Nations Framework Convention on Climate Change (UNFCCC) (Garg et al 2001(Garg et al , 2003. It has been reported that only about 12% of India's net GHG emissions comply with Tier III specified by the Intergovernmental Panel on Climate Change (IPCC 1997).…”

Indian Summer Monsoon Rainfall (ISMR) is one of the most well-documented areas of hydrometeorology; however, the processes associated with ISMR are not well understood. This attributes to the complexities associated with ISMR at multiple spatio-temporal scales. This further results in inconsistencies across the literature to assess the impacts of global warming on the monsoon, though this has huge relevance as a huge population of South Asia is dependent on the same. Here, we review and assess the existing literature on the Indian monsoon, its variability, and its trajectory in a warming scenario. We further synthesize the literature on its impacts on the hydrology of major river basins in South Asia. We also identify a few research questions, addressing which will add value to the understanding of the Indian monsoon and the associated water cycle. We have highlighted that there is a significant lack of understanding of how different large-scale and regional factors affect ISMR at different timescales. These impacts, in turn, get translated into hydrology and water sector in India. There is a need to know where we stand to combat the impacts of climate change on ISMR, which can be translated to adaptation by policy-making processes and water management practices in India.

“…Nanosorption is a promising and emerging technique, which involves the use of nanomaterials to sequestrate contaminants from different media [105]. As a superset in which nanosorption is subsumed, adsorption is widely seen as the favorable, economical, simple but effective remediation process for the elimination of contaminants derived from watery media [42,43,106,107,108]. It involves the transfer of the contaminant from a phase to another phase usually a solid [109].…”

Nanoremediation approaches have been applied to remove oil from surface and ground water as oil spills have been found to have long-term negative consequences for the ecosystem. Nanoremediation via the nanosorption mechanism of different environmental matrices in the world at large is at its formative stages despite the alarming and extensive prevalence of petroleum related environmental pollution. Over 9 million barrels of oil have been leaked in the last five decades, making that ecosystem one of the most deteriorated by oil exploration and extraction activities. The goal of this research is to assess the current status, trends, and future prospects of the nanosorption of surface and ground water in oil spill regions. High surface area of nanomaterials, wide spectrum of treatable contaminants, non-generation of intermediate or secondary products, as well as speed and extent of contaminant destruction give nanoremediation a superior comparative edge over other treatment technologies. Notably, the remediation efficiency of a cleanup is highly dependent on the type of material and treatment routes employed. It is imperative to employ a concerted and practical approach to the development of nanotechnology to combat the bedeviling oil pollution challenges faced in oil producing counties.

“…It is widely known that the power plants in India use distinct combustion technologies under varying operating conditions and the characteristics of coal in India are unique with lower sulphur content and higher toxic elements such as "Mercury" and "Lead". Mittal et al (2012) (Garg et al, 2002). The release of SO 2 is dependent on the sulphur content of the coal, whereas the concentration of oxygen and the flame temperature control the formation of NO.…”

Fine particulate matter (PM 2.5 ) predominantly comprises sulphates and nitrates, which results from sulphur dioxide (SO 2 ) and nitrogen oxide (NO x ) gases that are emanated from excessive industrial activities and transport systems. PM 2.5 is known to affect respiratory health in humans. Coal-fired thermal power plants are a major source of SO 2 and NO x gases. Evaluation of the dispersion characteristics of these precursor gases from the power plants would help understand the vulnerability. Meteorological conditions that prevail over the region would influence the dispersion characteristics. In this study, dispersion of SO 2 and NO from two major coal-fired thermal power plants in Andhra Pradesh, India have been studied using an integrated modeling approach of the Advanced Research Weather Research & Forecasting (ARW) model and Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model. Meteorological conditions are obtained at 3-km resolution using the ARW model and dispersions of SO 2 and NO is computed using the HYSPLIT model for the four seasons of winter, summer, monsoon and post-monsoon. Forward trajectories produced by the HYSPLIT model show diurnal variations and dispersion patterns show seasonal variations indicating the influence of meteorological conditions. Dispersion characteristics show high dispersion in winter due to calm and stable atmospheric conditions to insignificant in summer season due to stronger winds and higher atmospheric instability. The study establishes the usefulness of integrated meteorological and dispersion models for the evaluation of pollutant dispersion.
