SaveTheHills survey of landslides near Dikchu (East Sikkim) on 27Mar2023


 

LANDSLIDE 2

Following media reports on a major landslide occurrence at Sokpay, near DIKCHU on 26Mar2023, we made a quick visit to the region the next day. Our report:

Rainfall data for the month of MARCH of Mangan (District HQ of North Sikkim)
2021 - 249.9mm
2022 - 166.5mm
2023 - 272mm (upto 28Mar2023)
Dikchu is situated approx 2.5km (approx 21km by road) south of Mangan.

Location and Co-ordinates of the base (toe) of landslide
The landslide at Sokpay (Rakdong-Tintek block) is huge with the crown located at least 1500' above the toe. We could only survey the base (toe) of the landslide which is located very close to DIKCHU town because the landslide has cut off access to the higher reaches where several affected homesteads are located.
Co-ordinates and elevation: N27° 23.822' E88° 31.142'
Elevation: 2543ft (775m)

Brief history and date and time of occurrence
As per locals, the landslide at Sokpay took place between 3-4am on 26Mar2023.
However, they trace back the instability to 2016 when there was a landslide in the area and thereafter, smaller landslides taking place at regular (even yearly) intervals; with 'surveys' being conducted and talks of relocation also taking place but nothing being implemented.

Probable cause
This seems to be a mystery since there has been very little rainfall in this region since Oct2022. In Mar2023, Mangan and Gangtok region did receive 'excess' rainfall (see below)
But this amount and intensity of rainfall, in our experience does not trigger such a large landslide. Local people are quick to point out that it is NHPC's Stage V Dam on the Teesta river located at Dikchu as a cause and also the large power towers (pylons) at the top (crown) of the landslide as the probable trigger.
However, there is no study done to prove this.
Government officials are equally fast in saying the entire investigation is being done by the Department of Mines and Geology, Govt of Sikkim and that their report on the cause and remedial measures to be taken is awaited. They also point out that this area is landslide prone with many sinking zones - which even a cursory look at the region will prove as correct.
We also found no other evidence of large scale and recent human interference such as road/tunnel construction which could have triggered the landslide. Nor was there any erosion by a jhora or river in the close vicinity which could have caused erosion and triggered the  landslide which started from the hilltop.

Casualties and damage
There were no human lives lost even though the farmers lost cattle and pigs in the slide. 4 homes were totally damaged and 20 families have been shifted to temporary relief shelters by the government. Unlike the landslide in Pathing, both the media and government authorities seem to have mobilized immediately. The Government has implemented relief measures and also taken the help of the Power Companies to provide temporary rehabilitation to the affected families.
Road communications from DIKCHU to GANGTOK has snapped and the main road from DIKCHU to MANGAN may also be affected in case the landslide is reactivated during the oncoming monsoons.

 

 
 

LANDSLIDE 1

We discovered this landslide at Tumin Shelay, in the same area almost by accident. This huge landslide is more than a year old and seems to have been triggered by rain in an agricultural area. The farmers have lost almost 3 acres of paddy field there and around 3-5 families have been compelled to relocate. A local person guided us to the landslide which has affected the lives of the farming community in more ways than one - tourism which was coming up around a beautiful waterfall in the vicinity has died a premature death.
Like many landslides which occur in remote areas, this one never hit the headlines - in fact, I had never even heard about it, until we reached the place searching for the recent DIKCHU slide.

Location and Co-ordinates of landslide
Located at Tumin Shelay village.
Co- ordinates near the crown: N27° 19.492' E88° 30.134'
Elevation: 4082ft (1244m)


We will be uploading a short documentary, on our visit to these landslide sites. The documentary will include interviews, images and drone footages of the landslides.

Tanyang, a village on the edge (11Sep2022)

Tanyang, a tiny village (in Samalbung GP, Kalimpong 1) composed almost entirely of people from the Lepcha community is approximately 2hrs drive from Kalimpong. It is a village of farmers and as such, land being their most precious asset, the loss of 10-12 acres of land due to the landslides creates a huge dent on the earnings and livelihoods of the people.
I was rather surprised to hear of a recent landslide in the village because of the mild summer monsoons this year and a deficiency in rains in July and August 2022.
We were in the landslide affect areas adjoining the main village yesterday where we did a drone survey of the landslide.
A Google - Earth image of the landslide dated 1/1/2021 is placed below:

The local people, who are often the best judges, offered various reasons for the cause of the landslide:
  • It was initially triggered during the major landslide disaster of Oct 1968, which is totally believable since many of the old landslides started with this event.
  • Some of the villagers said it was the Sep2011 Sikkim earthquake which had created the cracks and the fissures.
  • Everyone seemed quite sure that the heavy rainfall on 26Aug2022 had caused the recent landslides which necessitated the evacuation of 10 families from the immediate vicinity of the landslide.
  • Some said water was oozing out from inside the slide which probably caused the slide.
  • One could safely rule out human activity as a probable cause. There is no urban built up areas here, population is low, no major road construction or other developmental activity. No jhora nearby which could have caused the erosion and the river at the base of the mountain is quite far and could not have caused toe erosion.

     
     
    10 families, including women and children had been evacuated and were housed in temporary structures and also in the ICDS building

When interviewed the women folk especially were apprehensive of the future and wanted to be relocated close by somewhere and quickly since the future of the family and children were at stake. 

 Media report of the landslide is placed below:
The link to the drone footage and interviews will be put up as soon as it is ready.

Mungpel: A village living on the edge (03Jan2021)

 As a part of our landslide surveys, I visited Mungpel, a small village in Pabringtar GP of Kalimpong (Block -1) on 03Jan2021. The village consists of 30 odd houses who are almost entirely of members of Limbu ethnic group. The sombre fact is that of these homes, approximately 10-15 overlook and are in the proximity of huge landslide.

We had carried out a landslide survey in this area in April 2011 and a map of the area from that survey is placed below:
Landslide history
As per locals, the landslide was insignificant until 2018 after which it has grown to its present size. This whole area receives very heavy rainfall and is thrashed by intense thunderstorms during the pre-monsoons but it is a pity there are no rainfall data from this place to relate the landslide activity.
However, the locals clearly said most of the damage was done during the monsoons of 2020 especially around end of Jun2020.
Coordinates of Mungpel Landslide:
N 26.95696° E088.54993°

At the base of the this hill there is a fairly big Durung khola (river) and a wonderful flat piece of land where the villagers do their agriculture and farming. As per the villagers the landslide was not due to toe erosion by the river and was caused by the inherent geology and heavy rain.
Yet another major landslide in the lower Sherwani area, nudges the Mungpel landslide and we have yet to survey that area.





As I have mentioned 3 families have already relocated to upper regions but some 10 other families also may suffer a similar fate - these monstrous landslides are seem impossible to control without serious study and funding.

Highlighting the forgotten plight of the people of Rabek and Ladam, Kalimpong District: Peter McGowran, King's College London (UK)


Over the past few months, I’ve spent a lot of time going through the various notes, photos and interviews that constitute my fieldwork data. This led me back to the field visit my research assistant Lochan and I took on 21/11/19 to the very remote landslide-affected villages of Rabek and Ladam, near Rishap in Kalimpong’s Algarah Block. Since the day we visited, I’ve felt a need to highlight the seemingly forgotten plight of the people of Rabek and Ladam. It is for others to decide what should be done to help the people there.
Rabek and Ladam:
Rabek and Ladam are small, remote villages just beyond the village of Rishap. A rough GPS location is 27°07'32.8"N, 88°39'35.8"E.

Figure 1 – The location of the landslide in Ladam/Rabekin Kalimpong District.
Our visit:
Lochan and I visited Ladam and Rabek on 21/11/19. We found about it through the Kalimpong District Disaster Management Plan and contacted our interviewees by speaking to people when we arrived, as they gave us phone numbers. The area is around a two-hour drive from Kalimpong Town, followed by about a two-hour walk down the hillslope to reach the villages of Ladam and Rabek. It would have taken perhaps another hour to reach the lowest houses in the village, but we didn’t have the time or energy to do that!In the village itself we interviewed one of the leaders of the affected community. From there, we climbed back up to the top of the hill and then visited the camp where most of the displaced currently live. We spoke to few of them there in a sort of open discussion, led primarily by one member.It isn’t the easiest landslide to photograph because it is an entire hillslope. In the below picture, one of the lowest houses in the village can be seen, to give some sense of the scale of the affected area.

















 



Figure 2 – Part of the hillslope in Ladam/Rabek. The entire hillslope pictured is affected.
2015
From the 29th of June to around the 1st of July, there was extremely heavy rainfall in and around Kalimpong district. This triggered a number of landslides across the district and region, many of which were fatal – see here for Save The Hill’s coverage of the many other landslides that took place over those few days in 2015. Whilst there were no casualties in Rabek and Ladam, the landslides have caused immense suffering for the people living there. At the time, this was picked up by some local media outlets and we were toldthat many local politicians visited the area. There are three other sources of information I have found on this situation, though there may be more in Nepali news sources:
1.      Video news report by local news outlet KTV
2.      Facebook post from a local Facebook group (with photos)
3.      Facebook post from a local NGO
What happened?
Whilst the exact chronology of events in 2015 is not clear, what we do know is that the entire hillslope was sliding down at some point during this event, and that there were a number of small mud-flows, debris falls and other landslide-related phenomena occurring all over the area on the night of the 29th of June, 2015. Photographs of the aftermath can be seen here.
Whilst I have no geological or hard data to draw upon, it seems this entire hillslope has been unstable for decades, one interviewee said this is perhaps a legacy of the 1968 rainfall event in the Darjeeling and Kalimpong Himalaya. A few years ago in 2011, the Sikkim Earthquake seemingly unsettled the entire hillslope which Rabek and Ladam sit on, and a number of cracks and crevices appeared. Our interviewee said there had been a survey done by ‘some official with some machine’ shortly afterwards. It appears this survey didn’t materialise into any actions, but they did find the cracks and crevices underground. The interviewee also reported that the people here were quite used to small landslips happening in and around the area. As a result, they had an early-warning system of sorts within the grassroots community group known as ‘the samaj’, which most communities have in The Hills. The samajserves different purposes in each community it represents, including support during times of crisis, providing ‘rules’ of sort for the conduct of the community, or as a basis for community organisation as and when required. In Rabek and Ladam, if there is prolonged rainfall, samajmembers go around the village and tell people to leave their homes and take shelter in safer areas until the rain subsides. Our interviewee suggested that without this system, lives probably would have been lost in 2015.
Immediate impacts
Despite the fact there were no casualties, we were told around 44 households were displaced initially. Some of these houses were completely destroyed, some partially damaged and other households chose to stay elsewhere in the immediate aftermath for fear of further landslides. One of the main impacts has been the fact that the landslide has destroyed lots of agricultural land, changed water courses and sources, and rendered the hillslope largely unsafe for habitation. Our interviewee told us that survey by the Krishi Kalyan Samiti (KKS), a farmer’s welfare cooperative that works all over The Hills, confirmed that this area was unsafe for habitation.Photographs of the relief camp and some can be seen in the Facebook post linked above. There is also more information on the immediate aftermath in the news report linked above.
The response
After the landslide, many of the people of Rabek and Ladamfaced homelessness. According to our interviewee, 20 households received an amount of 1 lakh rupees each from both the District Administration and the GTA. They also received immediate relief supplies and rations after a number of days. I would assume these relief materials also included the relief camp shelters. After weeks of living in temporary shelters, local politicians such as Bimal Gurung and Harka Bahadur Chettri—who in 2015 wielded some considerable power locally through the Gorkhaland Territorial Administration (GTA)—were able to negotiate with the Forest Department to allow the affected residents to set-up camp in some nearby forest land which they had previously used as a cattle-grazing area. As far as we can surmise, both the use of the area for cattle grazing and the agreement for (re)settlementwere done on the basis of verbal agreements, with the lattersupposed tolead to a more permanent settlement at some unspecified point in time in the future.This leads me on to the major problem that remains:5 years later, 19 of the families are still living there.
What’s happening now?
Politics moves quickly in The Hills. The politicians who secured the verbal agreement for the resettlement of the people of Rabek and Ladam no longer have any real power, and the verbal agreement has pushed the people of Rabek and Ladam into a marginal existence, somewhere between their old land which is unsafe and no longer productive, and a political and administrative black hole that seems incapable of resolving this problem.I have listed some of the key issues below:
·        The land which these people own and used to live on is unsafe.They can no longer reside there. The panchayat cannot build on this land because it is deemed unsafe for habitation following the survey by KKS. Besides, the amount provided for reconstruction is probably insufficient for the cost of building homes in The Hills, especially in remote locations such as these.
·        The land they own is now totally unproductive. These people used to be successful land-owning farmers who lived off their land. They have now lost these livelihoods. To get by, most of those who are able work as daily-wage labourers, primarily in the numerous homestays which have appeared there recently. Some reported that this amounts to around a 90% loss of annual income. This means they are unlikely to be able to relocate by their own means.
·        The panchayat system is unable to help them because they are on forest land. Those affected told us they hadn’t been offered any other alternative land.
·        They are not able to legally build the infrastructure which would allow them to ‘permanently’/comfortably settle here. In India, Forest Reserved Land is not available for human habitation – or any other human activity of note. Only in the last year or so—after four years—have they managed to negotiate facilities such as toilet buildings, electricity, and an internet connection. There are many young children living here. The only way you can get permission to settle on forest land is by acquiring a ‘No Objections Certificate’ (NOC) from the Forest Department, but this must be approved at a state or national level. There are stories locally of these NOCs taking decades to get approval.One of the interviewees said: ‘we are sandwiched’.
It was not the fault of anyone that their homes became unsafe and that the productivity of their land is gone. This was a natural hazard. However, the situation that they now find themselves in is not natural but the result of numerous social, political and economic factors that have created conditions of vulnerability. The outcome of this combination: of the hazard and the vulnerable conditions, has been a long, drawn out disasterthrough which these people have suffered. This event has knock-on effects and may make these people more vulnerable to other hazards such as COVID-19, and the impacts this has already had on rural food security in The Hills.
What can be done to reduce the vulnerability of the residents affected by the landslides in Ladam and Rabek?
