The levelized cost of electricity (LCOE) and environmental advantages of coal-CSP hybrid systems are presented by simulating the hybrid system in two modes at three locations in India with contrasting DNI profiles. The cost of additional energy generated due to SAFWH in booster mode is up to 51.4% less as compared to a stand-alone CSP. In the fuel saver mode, up to 40 thousand tons of coal can be annually saved with SAFWH, thus reducing CO2 emissions by 1.7% as compared to a stand-alone coal-fired plant.

Coal mines must incorporate social and ecological sensitivities from the planning stage up to mine closure to meet India’s Sustainable Development Goals. The Normalized Vegetation Difference Index (NDVI) is useful to assess the environmental impacts of mining operations on the air quality and vegetation around coal mines and monitor the progress of post-closure activities.

The performance of the State-owned electricity distribution companies (DISCOMs) that distribute 96% of the electricity in India is critical for the country’s energy security. However, the current studies are not suitable for assessing the performance of India’s DISCOMs in an integrated manner since their underlying models are fragmented. This study presents the development and application of an integrated FOBC framework which is a balanced scorecard including 32 key performance indicators related to finance, operations, business processes, and customer service.

The 2030 Agenda for Sustainable Development, under Goal 6 (SDG 6), aims to ensure universal access to water and sanitation. SDG-6.1 focuses on achieving safe drinking water for all by 2030. India's Jal Jeevan Mission (JJM) targets providing tap water to rural households by 2024. This article discusses a study on water demand and availability in seven villages in Ballari and Raichur districts, North Karnataka. It reveals heavy reliance on groundwater due to inadequate surface water. Only 14% of households meet JJM standards, with projected worsening scarcity.

The 2030 Agenda for Sustainable Development includes Goal 6 (SDG 6): ‘Ensure availability and sustainable management of water and sanitation for all’. SDG target 6.1 aims to achieve by 2030 ‘universal and equitable access to safe and affordable drinking water for all’. The Government of India has also launched the Jal Jeevan Mission (JJM) to provide potable tap water to every rural household by 2024.

We hereby present the variability of fine particles (PM1 ≤ 1 micron) that has not yet been investigated under the influence of COVID-19-induced lockdown in three major cities of different climatic zones in India. We unfold the baseline level of PM1, a level to which the population is chronically exposed and extremely critical for epidemiologists for fixing health markers. This has been achieved using the saturation point methodology under fair weather conditions. The baseline level of PM1 for Delhi and Mumbai is found to be 13 µg m− 3 and 9 µg m− 3, respectively.

A tribute is paid to Prof Bikash Sinha describing his pioneering research and his contribution to leading Variable Energy Cyclotron Centre and Saha Institute of Nuclear Physics on to a path of glory and initiating international collaborations with several Institutes, including CERN Geneva and BNL, Upton, New York, USA.
