According to the data released by the Central Water Commission (CWC), water levels in India’s major reservoirs and river basins have fallen to 21 percent of its average for the last 10 years. The data has also revealed that except the Indus, the Narmada, and the west-bound rivers of the south, the water level in all the river basins is less than the average of the last 10 years. The worst affected are the Kutch, the Tapi and the Sabarmati in Gujarat; the Godavari, the Krishna and the Cauvery in southern India, and the Mahanadi from Chhattisgarh to Odisha in eastern India. The precarious state of the reservoirs have pushed thousands of villages across western, central and southern India towards a possible water crisis.

As per the study conducted by IIT Kharagpur, economic growth is reducing faecal pollution in the groundwater in North India, Faecal pollution plays a key role in spreading waterborne diseases in the densely populated Indo-Ganges-Brahmaputra river basin. The study made first-time observations on the significant reduction of faecal coliform pathogen concentration in the spatially variable groundwater from 2002 to 2017. The study determined the economic development trends and correlations using night-time light data instead of gross domestic product (GDP) or other economic growth data.
Researchers, led by Avinash Ade at Savitribai Phule Pune University have found an answer to one of the biggest environmental problems—plastic pollution. The researchers have identified certain fungi with high polythene degradation potential from mangrove rhizosphere soil collected from 12 different locations in five coastal states—Kerala, Karnataka, Maharashtra, Goa and Gujarat. Among the 109 fungal isolates that the researchers obtained, Aspergillus terreus strain MANGF1/WL and Aspergillus sydowii strain PNPF15/TS have been found to be the most efficient polythene degraders.
