GLOF Threat in Himachal Pradesh

According to the studies carried out by the Centre, number of such lakes in Satluj basin has increased from 38 in 1993-94 to 390 in 2015.

SHIMLA- Scientists have already warned Himachal Pradesh about quakes and, indeed, abnormal seismic activity in the Himalayan belt was observed during past couple of years. Now, the State Centre on Climate Change of the State Council for Science Technology & Environment has warned Himachal Pradesh regarding devastating floods as melting of glaciers is causing formation of more lakes. Outburst of these lakes could unleash massive amount of water leading to floods.

The government has been advised to regularly monitor changes in these lakes, especially the smaller one in the higher Himalayan region of the State. Attention of government in this case is critical for averting any future eventuality in Himachal and loss of precious human lives, said the Centre.

To understand the situation, which is in this case is rapid growth in formation of small lakes due to retrieval of glaciers, let’s go through some review.

The state of Himachal Pradesh invariably experiences flash floods, the cause of which is unknown. In the year 2000, the Satluj valley experienced the heaviest floods causing economic loss of more than 800 crores. The cause of this flood event was not known to the experts that whether the floods were caused by cloud bursting or due to Glacial Lake Outburst Floods (GLOF) phenomena as it started from the Tibetan Himalayan Region.

The formation of landslide dammed lakes in high altitude zones such as Parachoo in the upper catchment of Spiti basin in Tibet caused tremendous threat to the life and property located in the downstream areas since its inception in the year 2004.

The recent tragedy of 2013 in the Uttrakhand Himalaya has also been correlated with the bursting of a lake having a total area of about 08 hectare in front of the snout of the Chorabari glaciers that caused widespread damage in the downstream areas besides the heavy rainfall in the area.

Causes and Threats of GLOF

As per various studies carried out in the past, Himalayan glaciers are in a state of general retreat since 1850. In the Himalayas, during the retreating phase a large number of lakes are being formed either at the snout of the glacier as a result of damming of the morainic material known as moraine dammed lakes or supra glacial lakes formed in the glacier surface area.

Most of these lakes are formed by the accumulation of vast amounts of water from the melting of snow and by blockade of end moraines located in the down valleys close to the glaciers. In addition, the lakes can also be formed due to landslides causing artificial blocks in the waterways. The sudden break of a moraine/block may generate the discharge of large volumes of water and debris from these glacial lakes and water bodies causing flash floods namely GLOF.

The sudden bursts of lakes can happen due to erosion, a buildup of water pressure, an avalanche of rock or heavy snow, an earthquake, or if a large enough portion of a glacier breaks off and massively displaces the waters in a glacial lake at its base. There are number of such events that have happened in Nepal Himalayas but no such event has been reported so far from Indian Himalayas.

According to the State Centre on Climate Change of the State Council for Science Technology & Environment, which has been carrying different studies in the Himachal Himalaya since 1993, number lakes has increased manifold in last two decades.

Lake Formation Increasing River Basins

Satluj Basin

GLO Floods In Himachal Pradesh

According to the studies carried out by the Centre, number of such lakes in Satluj basin has increased from 38 in 1993-94 to 390 in 2015.

Out of these 390 lakes, 42 lakes have area more than 10 hectare, 45 between 5-10 hectare, and remaining 303 lakes have an area less than 5 hectare.

Chenab Basin

Likewise the Chenab basin which mainly originates from the Himachal Himalaya, total number of lakes has increased from 116 in 2013 to 192 in 2015, which is almost four times than the number of lakes identified during 2001.
Out of these 192 lakes, 04 lakes have area more than 10 hectare, 6 lakes between 5-10 hectare and 182 are the small ones having area less than 5 hectare.

Beas Basin

In the Beas basin, number of lakes has gone up from 67 lakes during 2013 to 89 lakes in 2015, revels satellite data. Further analysis of these 89 lakes reveals that 80 lakes are smaller one having area less than 5 hectare, 07 lakes with aerial range between 5-10 hectare and 02 lakes which are having area more than 10 hectare.

Ravi Basin

Moranic Lakes in Himacahl PRadesh
The Ravi basin had total 22 lakes in 2013, which has now increased to 34 in 2015. When seen based on aerial distribution ,it is found that 03 lakes are having area more than 10 hectare, only 01 lake is having area between 5-10 hectare and 30 lakes are such which have area less than 5 hectare.

Need of time

Number of lakes in Himalayan River Basins

Based on the above analysis carried out by the Centre for the year 2015, it is evident that there is a considerable increase in the number of moraine dammed lakes (GLOFs) in each basin which reflects that formation of such lakes in the Higher Himalayan region is indicating an increasing trend. The higher number of smaller lakes i.e. lakes with area less than 5 hectare indicates that the effect of the climatic variations is more pronounced on the glaciers of the Himalayan region resulting in the formation of small lakes in front of the glacier snouts due to the damming of the morainic material.

The lakes with area more than 10 hectare and those with area between 5-10 hectare are more vulnerable sites for causing damage in case of bursting of any one of them.

Therefore, a proper monitoring and change analysis of all such lakes in higher Himalayan region of the State is critical for averting any future eventuality in Himachal Pradesh, so that the precious human lives are saved.

Another aspect of this report is about climate change caused by rising carbon emissions. Himachal need to pay attention to check air pollution. Currently, the Chief Minister Virbhadra Singh and his minister hardly believe in theory of global warming or glacier melting. Annoyed over NGT’s ban on fossil fuel vehicles into Rohtang Pass region, the CM had claimed that there are actually no glaciers around Rohtang. Vehicular emissions are excess and widespread with literally no check on it.

After 15 Years of Passing of Forest Rights Act, Implementation in Himachal Still in Doldrums, Jeopardizing Ecological Conservation

Forest rights fight in himachal pradesh

Shimla-‘Planting a tree to celebrate World Environment Day has been reduced to a symbolic tradition. But is this enough for the conservation of our ecology? The efficacy and use of plantation drives are being questioned all across the world today. These drives, especially when conducted by the government tend to be a wastage of resources due to poor survival rates, said environmental and community groups in Himachal Pradesh in a joint statement released recently on World Environment Day.

Further, trees are just one part of our ecosystem which comprises soil, grasslands, scrubs, wetlands, wildlife and even human beings, the statement said.  

In India, especially in the Himalayas communities have co-existed with nature since times immemorial – dependent on it for day-to-day life and livelihoods, the groups said. Because of this connection between forests and local livelihoods and culture-communities across the landscape fought to protect the ecosystems they inhabit from destruction – be it the Chipko movement in Uttarakhand 50 years ago or the recent struggles in the tribal district of Kinnaur to highlight the ill-effects of dams and hydropower projects – indigenous and forest-dependent people have protected forest resources, they said.

“It is unfortunate then that these historical custodians of forests were labelled ‘encroachers’ and ‘thieves’ as their livelihoods were displaced from forests sometimes to build dams, highways and cities and at other times in the name of conservation were restricted from using the forests citing forest laws,” the statement said.

The groups said this has happened in Himachal too, where communities like pastoralists and farmers are slowly getting alienated from the forests. This jeopardizes their capacity to protect the forests too – whether from natural calamities like fires or indiscriminate felling. 

Forest revival and afforestation programs, it is understood the world over, are only successful when local communities are made in charge and are given full access to use the forest and make decisions about its management.

“We have examples of community forest management like Gramya Jungles of Orissa and Van Panchayats of Uttarakhand. This became part of the Forest Policy in 1988 which is why programs like Joint Forest Management were planned for participatory governance of forests. However, in these too the forest department retained their control and communities were used as labour to plant trees,” the groups highlighted.

Based on these experiences and the repeated evictions of forest-dependent people from their rightful use it became apparent that there was a need for a law that recognised the community’s right to both use and protect/ govern the forest, they said.

It was after years of struggle that the Forest Rights Act 2006 was passed by the parliament of India. The Act recognises individual and community rights over any kind of forest lands for those dependent on these for their bonafide livelihood needs before 13th December 2005. The act also recognises development rights and community management rights. Himachal, where 2/3rd of the landscape is legally classified as ‘forest’ – there is a tremendous need and potential to implement this law to secure the land and livelihood rights of people on forest lands be they for fuelwood, fodder, pastures as well as farming and shelter. 

The statement said today it has been 15 years since the passing of FRA but in Himachal, its implementation is in the doldrums.

“While 20 lakh forest rights claims have been accepted all across the country in Himachal only 164 claims have been recognised whereas 2700 are pending with the administration at various levels. The key reasons for the poor implementation include – lack of political will, misinformation about the act amongst the line officials, distrust of the people leading to non-filing of claims and inadequate awareness amongst common people,” the statement said.

It further said that, ironically, the state government has shown great enthusiasm in using this act to grant forest land for village development activities, the rest of the rights namely individual and community forest use and management rights are languishing due to state negligence and actively blocking the granting of these rights. 

The groups further highlighted that in the last 5 years, community voices from Kangra, Chamba, Kinnaur, Lahaul-Spiti, Sirmaur and Mandi have been raising the demand for the implementation of this law in the state.  It was after this that the state government was forced to announce that it would implement the Forest Rights Act in a mission mode in the state in 2018. The tribal department also worked on training and making educational material on the act. However, these are yet to be properly distributed at the village level.

The joint statement further added that in March 2020 post the pandemic led lockdown the FRA implementation process received a setback. Even as gram sabha meetings and FRC processes came to a grinding halt the economy too got hit. During this time, it became evident more than ever that it is the land and forest-based livelihoods that are available to rural communities to fall back on for survival. 

“Whereas the Government should be focused on strengthening land and nature-based livelihoods for the local communities. However, the focus of the state remains on pushing destructive commercial ventures in ecologically fragile areas and valuable farmlands of the state,” the groups said.  

The coronavirus has taught the world what the climate crisis had already indicated – that we will continue to be victims of such crisis as long as the ecological destruction continues unabated, the statement said.

“This calls for a change in the model of ‘development’ which prioritises the basic needs and services rather than run blindly after economic growth which is meant to profit companies and contractors”, the groups said.

The statement also said that it is the communities who will now have to believe in their own capacity to manage lives and resources and also call the government to account if our natural resources have to be protected for future generations.

Himachal: Report Forest Fires on Toll-Free Numbers 1077 and 1070

Published

on

helpline for Forest Fires in himachal pradesh

Shimla-Forest fire is a recurrent annual phenomenon in Himachal Pradesh and causes losses worth several crores every year. Dry spell and summers make forests, especially chir pine forests, highly vulnerable to forest fires. These forest fires not only damage the forest wealth but also hit wildlife and biodiversity in general. The forest department attributes most fires to human factors.

Like every year, the forest department has claimed that it is all geared up and ready to combat forest fires this year too. Principal Chief Conservator of Forests Dr. Savita on Monday held a virtual review meeting with Forest Circles on preparedness for forest fires in the state.

She said that the Forest department was well prepared to fight the forest fires and a rapid forest fire fighting force and rapid response teams had been set up at forest division and range levels.

“Approximately 40,000 man-days of fire watchers would be engaged by the department in addition to existing frontline staff for preventing and combating forest fires,” she said. The state disaster control room with toll-free number 1077 at the state level and 1070 at the district level were operational for reporting of the forest fire by the local community, she informed.

Dr. Savita said messages regarding forest fire had been shared with the members of the rapid forest fire fighting force, in which approximately 50,000 volunteers had already been registered. Awareness to the community was also conducted through Nukkar Nataks, songs, speeches and other activities at different locations in the state. Besides, a massive state-level awareness program was also conducted at 45 places from 10 to 17 March 2021

She said that the department had created forest fire lines and did control burning and also constructed water storage structures in the forest areas to combat forest fires. Additional multi-utility vehicles and water loaded tankers in 80 fire-sensitive ranges had been engaged for three months. She that matter regarding Standard Operating Systems (SOPs) for requisition of helicopter services for dousing the forest fires had been sent to the Government for approval.

Annual Bird Count in Himachal Pradesh 2021

Shimla-The habitat of migratory and resident water-birds in Himachal Pradesh has gradually improved, said Forest Minister Rakesh Pathania.

The annual water-bird count at Pong Dam Lake Wildlife Sanctuary was conducted in the first of February, 2021 and the exercise was conducted under restrained conditions due to the prevailing Avian Influenza outbreak in Pong Dam Lake as well as the COVID-19 Pandemic, he said.

The exercise was conducted by Wildlife wing of Himachal Pradesh by deploying 57 staff members in 26 sections of the sanctuary for counting the water-dependent birds.

Total 108,578 birds of 96 species were counted during this year. Out of the total number, 101,431 of 51 species are water-dependent migratory birds and 6,433 of 29 species are water-dependent resident birds. As many as 714 birds of 16 other species were also recorded. The total population of the flagship species, Bar-Headed Geese, is 40,570.

The other species which have higher population count during this year are Eurasian Coot (24,163), Northern Pintail (12,702), Common Teal (8,444), Little Cormorant (3,649), Great Cormorant (3,410), Grey Lag Goose (2,297), Northern Shoveler (2,275) and Common Pochard (2,138). The species which find noticeable mention are Red Necked Grebe, Great Bittern, Lesser White-Fronted Goose, Red Crested Pochard, Ferruginous Pochard, Pied Avocet, Northern Lapwing, Peregrine Falcon etc. During the counting exercise, one Bar-headed Goose and one Grey Lag Goose with collars were also spotted.

This year the Annual bird count exercise assumes significance, considering the Avian Influenza outbreak in the Wildlife Sanctuary. Further, the Minister expressed satisfaction over the timely and effective containment measures taken by Wildlife Wing to control and contain Avian Influenza outbreak in the Wildlife Sanctuary.

PCCF (Wildlife) Archana Sharma and CCF Wildlife (North) Dharamshala Upasana Patial also participated and supervised the Annual Water Bird Count.

The total population of birds, as well as number of species, counted this year are marginally less as compared to last year, probably due to the impact of Avian Influenza outbreak which was first reported on 28th December 2020.

Although the total population of water birds declined during the peak of the Avian Influenza outbreak, there is a gradual increase in the total population of birds, the Minister informed.
