The 2009 fatal landslide map



This post presents the data from the Durham University Fatal Landslide database for 2009. This is a map of fatal landslides only with each red dot representing a single landslide recorded on the database.

Comment by Praful Rao

From the above map it is apparent that we live in one of the most hazardous areas in the world as regards landslides, yet nothing much has changed
... so I am pretty much sure that next year we will have yet another map (of 2010 obviously) with those red dots all around us. What a pity!

Excerpt from Himalayan Times (Kathmandu, Nepal))

Please refer to the last blog ("Digging one's own grave"), rather coincidentally the "Himalayan Times" from Kathmandu (see here) also featured this story (connected with the same issue) on 04Jan2010.

Boulder,sand export barred
Last Updated : 2010-01-04

KATHMANDU: The parliamentary Natural Resources and Means Committee today directed the government to immediately stop exporting boulders, crushed stones and sand to India, citing serious environmental threat to the Chure range due to over exploitation of the natural resources.
The decision was taken at a meeting chaired by committee chairperson Shanta Chaudhary. The committee has directed the Ministries of Home, Local Development, Industries and Forests to implement the committee decision.
Minister for Forest and Soil Conservation Deepak Bohara, who was present during the meeting, lauded the committee’s decision.
Lawmakers said over exploitation and export of the country’s natural resources had resulted in heavy landslides, flash floods, environmental degradation and massive deforestation in the fragile Chure range.
They even warned that the fertile Tarai region would turn into desert if human encroachment in the range was not immediately stopped. The trucks loaded with boulders are also the major cause of damaging country’s highways that can withstand load only up 12 tonnes, the lawmakers said. Those trucks, however, carry more than 20 tonnes.
The revenue earned from the export of these items is far less compared to the environmental degradation in the Chure range and damage to the national highways, they observed.
With the committee’s decision suspending the export of the boulders, crushed stones and sand to India, hundreds of crusher industries located in the Tarai from east to west would suffer and the investment made in this business would be at risk.
Nepali Congress chief whip, who is a committee member, said the country could not afford the damage caused by environmental degradation in the Chure hills for a few million rupees.
Abhisekh Pratap Sah, a lawmaker of the Madhesi Janaadhikar Forum, objected the committee’s decision and wrote a note of dissent.
Other lawmakers — Navodita Chaudhary, Prithvi Subba Gurung, Rana Dhwoj Limbu, Ram Kumar Sharma — alleged that the government had yielded to the commission agents and did not care about preserving the environment of the Chure range, which plays an important role in maintaining ecosystem in the Tarai.
Rupandehi, Morang, Bara, Makwanpur, Kapilvastu and Nawalparasi are some of the districts from where the largest amount of boulders, crushed stones and sand are exported to India, where they are used for the construction of highways, railways and buildings in Uttar Pradesh and Bihar.
The committee has also formed a sub-committee to come up with a policy regarding the use of the natural resources. The committee had called environment, local development, industry and forest ministers. But Bohara was the only minister to be present during the meeting.

Digging one's own grave


The sun, the moon and the stars would have disappeared long ago... had they happened to be within the reach of predatory human hands.                                                           - Havelock Ellis (1859- 1939)   
Some adverse impacts of uncontrolled river quarrying :-
a) Land degradation
b) Increase in erosion
c) Damage to infrastructure such as bridges, highways
d) Damage to Irrigation schemes
e) Damage to natural ecosystems
f) Irreversible adverse impact on riverine biodiversity
g) Ground water level (water table) lowering

- source "Issues and challenges in river management due to excessive sand mining in Sri Lanka" (http://riversymposium.com/paper08/Badra Kamaladasa.pdf)

As with so many such issues, more questions are raised than there are answers, the main questions being :-
a) Is there a saner way to continue the developmental work without ravaging the environment?
b) Where do you find alternative employment for the thousands who who eke out a living by working in the quarries?

An expert's ( Prof Nitin Som) view about landslides



" Landslides occur as natural phenomena in hilly terrains and also due to disturbances caused by construction activities, e.g., housing and transportation. Natural slopes which have established a balance with the geological and geotechnical features of the area get disturbed by human actions like mining, deforestation and road construction which perforce are required to fulfill the development needs of the area.
Landslides fail to attract as widespread attention as earthquake or cyclone because landslides usually occur in “remote” areas on the hills, often far away from the urban growth centres. Yet instances are plenty where landslides have killed thousands of people and the resulting economic loss to the region has been no less than that from a major earthquake or cyclone."

Automatic rainfall gauge installation at Kalimpong


Automatic rainfall gauges (ARGs) and Automatic Weather Stations (AWS) will certainly help us bolster our preparedness against landslides during periods of heavy rain during the monsoons in the future. STH had written to India Meteorological Department, Kolkata regarding installation of these in Kalimpong, their reply is placed below.
Darjeeling/Gangtok already have AWIS and their read out is available here

A quote from Carl Sagan



"Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.
It is up to us."
- Carl Sagan (1934-1996)

An Eye in the Sky :TRMM




The Tropical Rain Measuring Mission is  a joint space mission between NASA and the Japan Aerospace Exploration Agency (JAXA) designed to monitor and study tropical rainfall.
The website (http://trmm.gsfc.nasa.gov) is one of the MUST SEE stop overs of STH and is used along with that of India Meteorological Department (http://imd.gov.in) to send out SMS alerts on heavy rainfall warnings.
The photo above shows Cyclone "WARD" as it brews off the coast of Tamil Nadu today - IMD has already issued a severe weather warning for the area.
