A Sinking Village & a Stream that Floods in the Sun: Climate Change, Jahlma Nallah and Lindur in Chenab Basin

At the village of Jasrath in Lahaul and Spiti, the River Chandrabhaga’s current is swift and strong like a rambunctious toddler. The river is new here, birthed just 16 kms upstream at the confluence of the Rivers Chandra and Bhaga. Chandrabhaga will be named as Chenab only after a journey of about 400 kms downstream. Chenab is one of the largest tributaries of the River Indus whose expansive basin feeds over 250 million people in the heart of Asia.  

Lahaul and Spiti district in Himachal Pradesh is a cold desert with very little rain, but the narrow ribbons of land along the Chandrabhaga are emerald with willows, apple orchards and cultivated farms. This is precious land.

DRP NEPAL 2023: Vibrant debate about Hydro Projects

This provides an overview of Dams, Rivers & People related issues in Napel in just concluded 2023. While export of hydropower to India is central this year following Nepal PM’s June 2023 visit to India. Pancheshwar, the most ambitious of the projects have seen no real progress in spite of repeated statements. An agreement signed with India to export upto 10000 MW of hydropower in ten years has raised lot of hopes in both countries. The electricity trade has indeed expanded significantly in 2023. There is also renewed hope for Nepal succeeding in export of hydropower to Bangladesh via India, but this still needs some concrete success.

However, most interesting is the vibrant debate in Nepal media about adverse economics, impact on environment, biodiversity and disasters, in addition to displacement risk for thousands of people. Some called it costly madness. It also notes that climate change does not even figure in decision making process. The overview begins with that debate.

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?
