A pneumonia outbreak was primarily reported in the fall of 2019 in Wuhan, Hubei province, China, with the identity SARS-CoV-2, a novel coronavirus. It quickly grew from a local epidemic to a global pandemic and was declared a public health emergency by the WHO. A total of three prominent waves were identified across the globe, with a slight temporal variability as per the geographical locations, and has impacted several sectors which connect the world. By March 2022, the coronavirus had infected 444.12 million people and claimed 6.01 million human lives worldwide, and these numbers have not yet stabilized. Our paper enlightens readers on the seven strains of human coronaviruses, with special emphasis on the three severe deadliest outbreaks (SARS-2002, MERS-2012, and COVID-19). This work attempts a comprehensive understanding of the coronavirus and its impact on the possible sectors that link the world through the economic chain, climate conditions, SDGs, recycling of the event, and mitigations. There are many points that are raised by the authors in the possible sectors, which are emerging or are as yet unnoticed and thus have not been taken into consideration. This comprehension will leave sets of new challenges and opportunities for the researchers in various streams, especially in earth sciences. Science-integrated research may help to prevent upcoming disasters as a by-product of (existing) epidemics in the form of coronavirus. [ABSTRACT FROM AUTHOR]

Raipur of Chhattisgarh state, central India, is facing water problems due to rapid urbanization and altered hydrological processes despite adequate rainfall. Deteriorated surface water, diminished recharge and elevated pumping have reduced water availability in the region. Therefore, proper measures like managed aquifer recharge (MAR) need to be successfully implemented to conserve rain water for long-term sustainability. Hydrogeological data, combined with geophysical investigations lead to the construction of a conceptual model of the Chandi limestone aquifer for this purpose. The results indicate that the compact and massive limestone has negligible primary porosity, but solution weathering (karstification) has developed secondary pores at variable depths that favour recharge, groundwater storage and movement. The study helped to locate potential recharge sites that have significance in optimizing MAR structures such as check dams and injection wells. The hydrogeological model has a great significance in managing these complex and heterogeneous aquifers for better future water supply in the region. [ABSTRACT FROM AUTHOR]
