DRP NB 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?

July 2023 Bhutan Hydro Project Disaster: 23 Dead and missing

At least seven people were killed and 16 others missing in Bhutan after flash floods and landslides triggered by heavy rains washed away a section of a hydroelectric plant on July 20 2023[i]. They were washed away by the sudden burst at the residential area next to the worksite at Ungar village, according to a press release from the Prime Minister’s Office. Prime Minister Dr Lotay Tshering, who is in Lhuentse, said the devastating flashflood presented one of the biggest loss of lives and properties in recent memory, and shook the core of the nation.

DRP NB 170723: Man-Made Reasons That Make Flood A Disaster

Over the past 10 days, several Himalayan and North Indian states including national capital Delhi have been battling severe flood disaster which has already taken a heavy toll of human lives apart from displacing people in large numbers and causing massive scale and still unfolding destruction to public-private infrastructure which is still unfolding.

While at macro level the impact of climate change induced excessive and abnormal rainfall patterns is seen as a major culprit but the micro level analysis reveals the deep connection of human activities behind the devastation on ground.

For example, in Himachal and Uttarakhand it is increasingly becoming clear that the large-scale construction and widening of improperly designed and poorly executed highways projects have started proving a double whammy for the fragile hills and river systems.

DRP NB 030723: Peak Hour Tariffs to be implemented from April 2024

(Feature Image: Vyasi HEP power station at Hathyari, Dehradun. SANDRP, June 2023)

This announcement by the government is indeed much belated but welcome step that India plans to increase peak hour power tariff compared to non-peak hour power tariff, beginning with commercial and industrial consumers from April 2024 a year later for others excluding agriculture consumers. The notification mentions it as daytime tariff (during solar hours) and night time power use, but this essentially also helps peak management.

This will not only put a premium on peak hour power consumption and hence generation, but also hopefully ensure that assessment of impacts of the peak hour power generation including at hydropower projects is done and done in a credible way, along with compensating those affected. It will also hopefully ensure that existing hydro capacity is used optimally for peak hour power generation before going for new hydro projects in the name of increasing peak our power generation.

One also hopes that it will lead to better peak hour power management and also considering all the options for such power generation rather than pushing hydro projects blindly in the name of peak hour power generation.

Himachal Pradesh 25 June 2023: Cloud Bursts Damage 2 Hydro Projects

With the onset of south west monsoon 2023, Himachal Pradesh has witnessed multiple incidents of ‘cloud bursts’ leading to destruction in Solan, Shimla, Hamirpur and Kullu between June 24-25. The extreme rainfall and resultant flash flood spells have caused widespread destruction to farms, cowsheds, local roads, bridges, vehicles and other public infrastructural in these districts.

DRP NB 260623: National Framework for Sediment Management

A National Framework for Sediment Management is certainly a long standing requirement and any move in that direction would have been welcome. Not only because the sediment accumulation destroys storage capacity of India’s Dams, created at such massive costs. But also because sediment is an integral part of river flow and also very important for the rivers to stop or reduce erosion at deltas. There are other issues related to sediment including creation and disposal of toxic sediment and impact of sediment free water flowing downstream from the hydropower projects.

But we need much more serious and sincere efforts in this direction than what has been suggested in following government press release. The movement on such an important subject is so snail paced, half hearted, non-comprehensive, unscientific and non-sincere that it is not clear how this is going to help.
