A recent study published in Nature Geoscience highlights the relationship between monsoon patterns and marine productivity in the Bay of Bengal over the last 22,000 years. The research, conducted by an international team of scientists from India, China, Europe, and the United States, found that fluctuations in the Indian Summer Monsoon (ISM) significantly impact plankton growth, which is crucial for marine food webs and the overall health of aquatic ecosystems.

Key Points:

• The study emphasizes that both strong and weak monsoon conditions disrupt ocean mixing in the Bay of Bengal, leading to a significant decline in marine productivity by up to 50%.

• The Bay of Bengal, while constituting less than 1% of the world's ocean area, contributes nearly 8% of global fishery production, highlighting its importance to coastal communities that rely on fishing for their livelihoods.

• The research involved analyzing fossilized foraminifera shells to reconstruct historical marine conditions, revealing that extreme historical monsoon patterns corresponded with periods of reduced marine productivity, notably during the Heinrich Stadial 1 and early Holocene epochs.

• Disruptions caused by excessive freshwater from strong monsoons lead to decreased nutrient mixing, while weak monsoons exacerbate nutrient starvation due to reduced wind-driven mixing.

• The findings raise alarms about contemporary climate change, as current climate models predict similar patterns of monsoon variability, which could further threaten marine resources and food security for the millions dependent on the fisheries in the Bay of Bengal.

• Researchers are particularly concerned about future scenarios involving warmer surface temperatures and increased freshwater runoff, conditions that have historically accompanied declines in marine productivity.

This study illustrates the far-reaching impacts of monsoon variability on ecological systems and coastal communities, underlining the need to understand climate-driven changes to safeguard marine resources.

The Central Board of Direct Taxes (CBDT) has officially recognized the National Mission for Clean Ganga (NMCG) as an authority under section 10, clause 46A of the Income Tax Act, which allows NMCG to receive exemptions from taxes on its income. This notification was issued on April 22, 2025, and applies to income derived from activities related to NMCG's implementation of the Namami Gange scheme, a significant initiative by the Indian government aimed at cleaning the Ganga River.
