Big dams encourage inefficient use of water in India: Modi aide Navalawala

Taking a stance similar to one of Centre's staunchest opponents, Medha Patkar-led Narmada Bachao Andolan, the Narendra Modi government's water resources adviser BN Navalawala has taken strong exception to excessive dependence on big dams for solving India's water problems. Instead, he has called for adopting a mix of "efficient methods" in the use of water and laws to ensure that this becomes a reality.

Delivering lecture at the UN World Water Day Celebration seminar organized by the United Nations Development Programme (UNDP) in Delhi last week, Navalawala said, "Much water is lost as it is conveyed from reservoirs to fields, distributed among farmers, and applied to fields. Irrigation efficiency is estimated to average less than 40 percent."
Navalawala said, "Drawbacks of low productivity of land and water use are required to be leveraged upon in the future strategies of achieving food security", adding, "Making irrigation more efficient" could be achieved by "moving toward more sustainable water use", especially by "reducing irrigation needs just by a tenth".
While agreeing that "a wide variety of measures exist to boost agriculture’s water productivity", including "new and improved irrigation technologies, better management practices by farmers and water officials, and changes in the institutions that govern the distribution and use of irrigation water", Navalawala said, this is not enough.

"The vast water saving potential of these measures will not be realized until the economic policies, laws, and regulations that shape decisions about water use begin to foster efficiency rather than discourage it", he underlined. This could be done, he added, by strictly promoting "rainwater harvesting and micro-watershed development throughout the country."
Strongly favouring the need to "establish a constructive working relationship between civil society" at a time when the Modi government is sharply moving away from it, he suggested, NGOs working on water related issues alone can help "formulate a series of area-specific answers for the needs of arid, drought-prone or water-scarce areas."
Stressing on "on local solutions" and avoiding "‘development’ of the water-intensive kind", Navalawala said, there is a need to "arrest and reverse as quickly as possible the present disastrous overexploitation of groundwater as well as the loss of good water to pollution and contamination".
Currently chief advisor, Ministry of Water Resources, Government of India, as also water resources adviser of the Government of Gujarat for the last one decade, Navalawala had been India's water resources secretary under Prime Minister AB Vajpayee in early 2000s.

He said, "Linkages between water, economic growth and human development are proving no less than increasing threats to water security in various parts of the world", he said, adding, the result has been that India ranks one of the worst in Sustainable Water Use Index (SWUI).

When Pakistanis whispered: ‘end military rule’ — A Moscow memoir

During the recent anti-terror operation inside Pakistan by the Government of India, called Operation Sindoor — a name some feminists consider patently patriarchal, even though it’s officially described as a tribute to the wives of the 26 husbands killed in the terrorist strike — I was reminded of my Moscow stint, which lasted for seven long years, from 1986 to 1993.

Ahmedabad's civic chaos: Drainage woes, waterlogging, and the illusion of Olympic dreams

In response to my blog on overflowing gutter lines at several spots in Ahmedabad's Vejalpur, a heavily populated area, a close acquaintance informed me that it's not just the middle-class housing societies that are affected by the nuisance. Preeti Das, who lives in a posh locality in what is fashionably called the SoBo area, tells me, "Things are worse in our society, Applewood."

Tracking a lost link: Soviet-era legacy of Gujarati translator Atul Sawani

The other day, I received a message from a well-known activist, Raju Dipti, who runs an NGO called Jeevan Teerth in Koba village, near Gujarat’s capital, Gandhinagar. He was seeking the contact information of Atul Sawani, a translator of Russian books—mainly political and economic—into Gujarati for Progress Publishers during the Soviet era. He wanted to collect and hand over scanned soft copies, or if possible, hard copies, of Soviet books translated into Gujarati to Arvind Gupta, who currently lives in Pune and is undertaking the herculean task of collecting and making public soft copies of Soviet books that are no longer available in the market, both in English and Indian languages.

RP Gupta a scapegoat to help Govt of India manage fallout of Adani case in US court?

RP Gupta, a retired 1987-batch IAS officer from the Gujarat cadre, has found himself at the center of a growing controversy. During my tenure as the Times of India correspondent in Gandhinagar (1997–2012), I often interacted with him. He struck me as a straightforward officer, though I never quite understood why he was never appointed to what are supposed to be top-tier departments like industries, energy and petrochemicals, finance, or revenue.

Environmental report raises alarm: Sabarmati one of four rivers with nonylphenol contamination

A new report by Toxics Link , an Indian environmental research and advocacy organisation based in New Delhi, in collaboration with the Environmental Defense Fund , a global non-profit headquartered in New York, has raised the alarm that Sabarmati is one of five rivers across India found to contain unacceptable levels of nonylphenol (NP), a chemical linked to "exposure to carcinogenic outcomes, including prostate cancer in men and breast cancer in women."

PharmEasy: The only online medical store which revises prices upwards after confirming the order

For senior citizens — especially those without a family support system — ordering medicines online can be a great relief. Shruti and I have been doing this for the last couple of years, and with considerable success. We upload a prescription, receive a verification call from a doctor, and within two or three days, the medicines are delivered to our doorstep.

A conman, a demolition man: How 'prominent' scribes are defending Pritish Nandy

How to defend Pritish Nandy? That’s the big question some of his so-called fans seem to ponder, especially amidst sharp criticism of his alleged insensitivity during his journalistic career. One such incident involved the theft and publication of the birth certificate of Masaba Gupta, daughter of actor Neena Gupta, in the Illustrated Weekly of India, which Nandy was editing at the time. He reportedly did this to uncover the identity of Masaba’s father.

Revisiting Gijubhai: Pioneer of child-centric education and the caste debate

It was Krishna Kumar, the well-known educationist, who I believe first introduced me to the name — Gijubhai Badheka (1885–1939). Hailing from Bhavnagar, known as the cultural capital of the Saurashtra region of Gujarat, Gijubhai, Kumar told me during my student days, made significant contributions to the field of pedagogy — something that hasn't received much attention from India's education mandarins. At that time, Kumar was my tutorial teacher at Kirorimal College, Delhi University.

A sector under siege? War and real estate: Navigating uncertainty in India's expanding market

I was a little surprised when I received an email alert from a top real estate consultant, Anarock Group , titled "Exploring War’s Effects on Indian Real Estate—When Conflict Meets Concrete," authored by its regional director and head of research, Dr. Prashant Thakur. I had thought that the business would wholeheartedly support what is considered a strong response to the dastardly terrorist attack in Pahalgam, Operation Sindoor.
