उगम: Story of Godavari and Vaitarna’s Origin

Most Indian languages have a saying which goes something like: “Do not go looking for a river’s origin or a Rishi’s lineage”. I thought this was because these stories become eclectic and frankly scandalizing as we trace them. But while looking at several origins of River Godavari on the Brahmagiri Mountain, I realized that the meaning can be much simpler (or much complicated): It is difficult to decide on a single origin for a river.

Why India needs Dam Decommissioning policy and program

India’s Dams and decommissioning As per the Parliamentary Committee for Ministry of Jal Shakti, in its 20th report dated March 2023[i], the committee had asked the Department of Water Resources, River Development & Ganga Rejuvenation under the Ministry of Jal Shakti about the mechanism put in place in India to assess the viable lifespan and performance of dams and projects, which has a direct bearing upon the consideration for dam decommissioning. The Department had replied: “There is no mechanism to assess the viable lifespan and performance of dams… However, no information/recommendation from the dam owners has been submitted for de-commissioning of any of their dams.”

DRP 240723: Urgently need parameters that will truly reflect rainfall pattern

(Feature Image: – IMD’s District Wise Cumulative Rainfall Map for 01 June to 23 July 2023)

India received 389.2 mm rainfall till 0830 hrs on July 23, 2023 in SW monsoon. This being 5% above the normal rainfall till this date of 370.9 mm, India Meteorological Department and with it, the whole nation calls it Normal Monsoon. But anyone who is familiar with the rainfall pattern across India will not call it Normal.

We must urgently develop new parameters for describing the monsoon that also take into account spatial (across states, districts, Tehsils, blocks) and temporal variability. These parameters should take into account the departure from normal for each unit of space for each day and combine such departures to arrive at a figure that will better describe the monsoon for each unit of space. It can also take into consideration the high intensity rainfall events as also the longer dryer patches. This will help us understand not only the nature of monsoon rainfall, but also alert the farmers and everyone else but also help us understand how this pattern is changing over the years. This should not be so difficult for IMD to initiate and accomplish quickly. When aggregated at river basin level, this will also help us understand the actual rainfall pattern in each river basin but also how it is changing. Is this too much to ask?

Poster child for Interlinking follies: Damanganga-Vaitarna-Godavari project

Pictures above have been taken five days apart. One would think River Interlinking entails transferring water from the bountiful right to thirsty left. In case of Damanganga-Vaitarna-Godavari Link, it means the opposite: transferring water from dry Mokhada to the verdant Devnadi in Sinnar. Like many ILR projects, it highlights the farce that is “surplus” and “deficit” basins. More rainfall does not secure water access, nor does moderate rainfall negate it.
