This article which I wrote in 2023 on innovative idea by Sonam Wangchuk which could have been transformational for remote area our our hilly state Uttarakhand. But look way India treats its innovative mind and force the talent to leave the country causing the brain drain.

Pre-event (13 Jun 2024) and post-event (7 Aug 2025) satellite images of Dharali, Uttarkashi, India reveal how a sudden cloudburst unleashed mudflows that blanketed the Bhagirathi and Kheer Gad channels in thick grey sediment, erasing roads, orchards and buildings. #Disaster #Flood #ISRO #Cloudburst

Cloudburst-induced flash flood and debris flow devastated village in Uttarkashi, India today. A glacial sedimentary deposit at 6,700 m, 7 km upstream, triggered by intense rainfall, caused rapid debris flow through a steep nala, reaching Dharali in under a minute. www.linkedin.com/posts/pravee...

On August 5, 2025, a catastrophic cloudburst-induced flash flood and debris flow struck Dharali village, Uttarkashi, Uttarakhand, approximately 10 km from Harshil, causing significant loss and damage....

Concerning trend shown in the Earth Overshoot Day chart (1971-2025). The date moves earlier each year, with 2025 at 1.8 Earths indicating unsustainable resource use. Over-consumerism is a key driver. Super rich should reduce their carbon footprint.

I’m having trouble separating natural forests from plantations in my LULC maps using GEE—they often get merged into same class.I want to separate them using unsupervised classification only. What additional data, indices or processing steps would you recommend to distinguish them more reliably?

While analyzing FAO WaPOR Biomass data, I noticed a striking pattern along a river: one bank shows high vegetation growth, the other much lower. Remote sensing (RS) data reveals these stark differences in Total Biomass Productivity (TBP), possibly due to irrigation, soil type, or groundwater. #IWMI

Most rivers, especially in remote or rural areas, have no streamflow gauges. That makes it hard to predict floods, manage water or plan infrastructure. Researchers use LSTM to estimate upstream flow based on observed downstream flow. @ciroh.bsky.social
