Guest Article by Prof Mysooru R. Yadupathi Putty
Introduction This write-up is with regard to the news-paper reports on the “The Geological Survey of India (GSI) Report on the landslides in Kodagu”. This is based on the information furnished by the news-papers and by the scanned copies of the original report of the GSI. The report attributes the landslides to excessive rainfall and extensive slope modifications due to anthropogenic activities, and puts blame on the people who have been using the land to their benefit. This brief article is written in order to bring it to the notice of the authorities concerned, and the people in general, that some of the observations of the GSI are highly ill-conceived, mutually contradictory and technically unsound. They unnecessarily go to rake up untoward feelings and create an impression that the people of Kodagu (Karnataka’s ‘Male-naadu’, in general) responsible for pulling the wrath of the Nature on to themselves. The author of this critique is a Hydrologist, who has been working in the region on Runoff processes, Land-use and Soils for nearly three decades. The following is a review of the available material of the report, point by point. Continue reading “Landslides in Kodagu & Western Ghats: A critique of GSI report”
On March 14, 2019 the Spencer dam on Niobrara river, located south of Spencer in Nebraska state in USA breached, killing four people in the downstream. The Investigation Report about the disaster has been made public now on April 24, 2020. The remains of Spencer Dam — a skeleton of concrete and steel amid a sea of sand — became one of the iconic images of the March 2019 “bomb cyclone” flood that caused billions of dollars in damage across Nebraska.
Less than four months later, on July 2, 2019, Tiware dam breached[i] in Chiplun taluka of Ratnagiri district of Maharashtra, killing 23 people. The then Maharashtra Chief Minister Devendra Fadnavis on July 6, 2019 announced a Special Investigation Team (SIT) to probe into the disaster, the SIT was to submit a report in two months, but the report was submitted in January 2020, but the report is not in public domain. When SANDRP talked with the chairman of the committee, he disclosed that the report has been submitted to the department in early Feb 2020 and it can only be made public by the department once they accept the report. He revealed that the SIT had found that there were issues with material of construction (masonry in place of Concrete) and design of the conduit of the dam. He agreed that the report should be made public promptly, but expressed his helplessness in face of the norms in India. SANDRP also called Secretary, Department of Water Conservation, Govt of Maharashtra, but got no response.
There is a lot to learn for us in India in comparing the two dam breach incidents and how both are treated.

The Climate Risk Index Briefing Paper “GLOBAL CLIMATE RISK INDEX 2020: Who Suffers Most from Extreme Weather Events? Weather-Related Loss Events in 2018 and 1999 to 2018” released by the Environmental Think tank German Watch[i] on Dec 4, 2019[ii] made a media splash in India[iii] since the report ranked India as fifth country (it was 14th in 2018 report) most at risk in the context of climate change.
Indeed, it is worth taking note that maximum number of deaths (2081) and Economic losses (USD 37808 million[iv], equivalent to four times country’s annual health sector budget) due to climate change happened in 2018 in India. Both these numbers were highest among the top ten Climate Risk countries of the world in 2018. This is one of the many reports which are coming out on the occasion of 25th Conference of Parties happening in Madrid (Spain) in early December 2019.

The Oct 2019 rainfall all over India was 109.7 mm, 44% above normal expected rainfall of 76 mm, following 53% above normal in Sept 2019. The rainfall this month has been unusual and has had some major impacts. One of the reasons has been that the SW monsoon withdrawal continued well into Oct 2019, when it almost always gets over by the end of Sept. There were also several cyclonic circulations and depressions mostly from Arabian sea.

August 2019 Floods in Sangli and Kolhapur districts of Maharashtra have been historic. River levels washed away all past records many times over. New High Flood Levels (HFL) were reached multiple times at multiple places both in Sangli and Kolhapur. These districts, which form the fertile Black Cotton Soil belt of Maharashtra, are the floodplains of mighty rivers of the Krishna Basin: Krishna, Koyna, Warna, Panchaganga, Tarli, Urmodi, Dudhganga, Hiranyakeshi etc.
On the 8th August, Krishna breached its HFL: Highest Flood Level at two places in Maharashtra (Kurundwad and Arjunwad). On the same day, Warna and Panchaganga too crossed their HFLs at two places: Samdoli and Terwad (Kolhapur). Continue reading “Homes in Deluge: Aftermath of Maharashtra Floods 2019”
The latest update from IMD[i] on Very Severe Cyclonic Storm VAYU (issued at 0700 hrs on June 13, 2019) does not provide any specific risk of floods in any region, nor does it mention any possibility of persistent rainfall leading to risk of floods.
Another IMD update at 1200 hours on June 13, 2019[ii] says large parts of coastal Saurashtra may experience winds of 160 kmph starting June 13 afternoon, but there is no mention of risk of floods. It does give heavy rainfall warning: “Widespread rainfall with heavy to very heavy falls at few places and extremely heavy falls at isolated places in the coastal districts of Saurashtra” till 0830 hrs on June 15, 2019, in RED colour, the highest risk colour code used by IMD. Further this warning adds: “Flooding of escape routes. Minor disruption of railways, overhead power lines and signalling systems.” Among action suggested it lists: “Inundation of low lying areas along the above mentioned coastal districts due to heavy rainfall and storm surge… Evacuation from low lying areas of the above mentioned Districts, coastal Hutment dwellers, urban slum dwellers and people staying in unsafe house to safer places.” The Ministry of Earth Sciences also sends out these releases through PIB Press Notes as IMD functions under MoES.

Hiroshima Hiroshima’s moral grip on our consciousness extends, beyond the Hiroshima Peace Dome, straight to the heart of India’s most urgent problem. The problem of balancing urbanization, growth, floods, and droughts in the face of climate change.
In the summer of 2018 devastating floods and landslides (blamed upon climate change) ravaged western Japan. With an unusually high death toll, for a nation that is used to counting the collateral damage more in terms of economic loss, than in terms of human lives, this one left a tragic number of people dead. Floods washed away large parts of Hiroshima, Kyoto, Okayama and Ehime. I joined Prof. Moe Nakazora, an anthropologist with the University of Hiroshima on a study tour of two of the worst affected villages in the eastern part of Hiroshima. These were the villages of Hachihonmatsu and Kouchi. Both the villages are located in Higashihiroshima which had more than 2000 landslides.[i] Continue reading “Western Japan floods 2018: Hiroshima and the Summer of the Deluge”

Almost all the big dams in Cauvery Basin are full on the earlier ever monsoon date this year. This includes Krishnaraj Sagar, Mettur, Kabini, Harangi, Hemavathi and Bhavanisagar. They are almost full and have started releasing large flows to the downstream areas. This is when we are past just about six weeks of South West Monsoon, the North East monsoon would come after that. It means that the basin is facing major risk of floods in next 2-5 months. And yet Central Water Commission, India’s flood forecasting agency, seems to be in deep slumber. It has not even bothered to update the flood readings on its designated sites from the 2017 figures. Continue reading “Cauvery is facing very serious flood risk, but CWC is in slumber”
One of the key source of information about India’s water availability that the government provides and media and everyone else quotes is Central Water Commission’s weekly (updated every Thursday) “Reservoir Storage Bulletin”[i]. The Reservoir Storage Bulletin (RSB) currently tells about water storage position of 91 storage dams across India with total live storage capacity of 161.993 BCM (Billion Cubic Meters), spread over 18 states and 12 river basins. CWC uploads it with a disclaimer: “The Data contained in this Bulletin is as received from the State Government/Project Authorities.” Continue reading “CWC’s Weekly Reservoir Bulletin: Closer look warns of impending disaster”

Immediate Press Statement from Himdhara 02/12/15
In the last two weeks a half a dozen lives have been lost in the Kinnaur region alone in three separate incidents that have one thing in common – accidents at hydropower project sites. The first event took place in Burang village on the 18th of November 2015 where a penstock pipe burst of the 100 MW Sorang Hydro-electric project led to the death of three people. On 29th November, two labourers died in blasting operations in the 450 MW Shongthong Karchham project, some others were seriously injured. And on the same day in the Bhabha Valley, a young teacher lost her life in a landslide that occurred in the area.
