India's groundwater recovery may be misleading, as new assessment methods inflate annual recharge figures and discontinue on-ground verification
AFTER A decade of declining levels, India saw the stage of groundwater development, the ratio of annual groundwater extraction to the annual availability, reach 62 per cent in 2013. By 2017, this figure had worsened to 63.33 per cent. However, the most recent government assessment in 2023 shows improvement: the country's stage of groundwater development reached 59.26 per cent, with 73 per cent of assessment units now "safe" (a stage of groundwater development at 70 per cent or below). This is a marked improvement from 2017, when only 63 per cent of units fell within the safe category.
Experts warn that this apparent improvement might be a numbers game rather than a true reflection of on-ground recovery. They argue that a shift in groundwater assessment methodology introduced in 2017 has inflated the appearance of recovery. This revised methodology expanded the area considered in groundwater assessments and estimated more significant groundwater availability. Crucially, it also removed the requirement for on-ground verification of water levels, raising questions about the accuracy of the reported data.

BUILT TO BINGE
Over the past few decades, food companies have exploited basic human instincts to peddle ultra-processed products. Engineered to hijack the brain's reward system, these foods are silently fuelling a new addiction epidemic, and driving rising rates of obesity and chronic diseases. Urgent policy action is needed to reclaim control over our food environment.

Another farmer quits
THIS DUSSEHRA, Pitabasha did not go for the customary sighting of the Indian Roller, or tiha, as it is called in Odia. The bird is believed to grant wishes, and every year thousands of people flock to farms, fields and forests hoping to glimpse it and make a wish. But the 30-year-old farmer from Matupali village in Odisha stayed back. From that day, he also stopped calling himself a farmer.

REDUCED TO INSIGNIFICANCE
On October 12, the Right to Information (RTI) Act completed 20 years. Activists who monitor the Act, and former information commissioners, say that amendments by successive governments have rendered the law toothless. As per Central Information Commission's latest annual report (2023-24), the number of RTI applications rejected in the year was over 67,615—the highest ever. BHAGIRATH curates a conversation on what went wrong with the law that was sought to bring transparency and accountability in governance.

'Depopulation would mean fewer people contributing to advancement of knowledge'
Trends show that in a few decades, global population will begin to shrink. Once depopulation starts, no one knows how to stop it in a sustained way, write DEAN SPEARS and MICHAEL GERUSO, associate professors of economics, University of Texas at Austin, US, in their recent book, After the Spike. The authors, who are also economic demographers, argue that population decline will be detrimental to global progress and that a smaller population would not necessarily be better for the environment. In an interview with ADITYA MISRA, they say that the time to talk about depopulation is now because the search for a solution could take decades. Excerpts:
