The present rate of sedimentation in the Rewalsar Lake, 3.92 cm/year, was still much higher than that of the other north-western Himalayan lakes which is less than 1 cm/year
MANDI– Rewalsar Lake in Mandi district of Himachal Pradesh, India, has come into lime-light for mass death of thousands of fish in just two days. News reports even suggested that 90 percent of fish in Rewalsar are now dead. Before fish started dying, the color of the water suddenly turned muddy on April 18, 2017. For next two days, fishes continued to die. From usual green, the color changed to muddy. Leela Vashishth, a resident of Rewalsar, lodged a complaint with Balh police station on April 19 on suspicion that some unidentified person could have contaminated the lake water with chemical or other sort of poison to kill the fish. A case of mischief by killing animals has been registered. It’s indeed a wise thing to consider this possibility as well. However, mass death of fish isn’t a surprise, and the lake doesn’t require someone to poison it to kill aquatic life. It’s already dying.
The lake has eventually reached on the verge of dying due to pollution, sewage discharge, rainwater flooding, sedimentation, siltation, excess growth of weeds, and mess created by visitors. Slumber of the administration is again apparent.
Located at 1360 meters above sea level, Rewalsar, also known as Tso Pema to Buddhists, is one of the most unique places in Himachal that possesses a diverse and rich history. The lake is of great spiritual and religious importance to three religious communities, Sikh, Budhisht, and Hindus. There are monasteries, a gurudwara, temples of Lord Shiva and Lord Krishna, and saint Lomas. This pristine lake is formed in the hollow of the mountains and the history dates back to the times of Budhisht Guru Rinphoche. There is a wonderful story associated with the formation of the lake. It used to be an amazing place. But now, the pollution and siltation is killing it.
The degrading condition of the lake was aptly brought to the attention of the district administration and authorities responsible for conservation and protection of the lake since last seven to eight years. It was not the first time that fishes have died in the lake.
Thousands of fish had died in the Rewalsar lake in July 2014 too. The authorities had cited flooding of rainwater into lake as the reason for death of fish. Excess dispersal of feed to fish by pilgrims and tourist was another major reason, which continued despite demand of ban on this practice.
After this incident, the Pradhan of the Nagar Panchayat, Bansi Lal Thakur, had told a Hindi Daily that the Chief Minister had laid foundation stone for establishment of sewerage system on May 11, 2012. The CM had allotted budged to the Irrigation & Public Health Department, and had asked to complete the work as soon as possible. Sadly, the small township settled on the boundary of the square-shaped lake still lack sewerage system. He had also said that DPR was prepared to remove silt, but the department hadn’t move a muscle in reality.
A report had appeared in 2015 in which it was revealed that the lake is overcrowded as there is no control on population growth of fish. The area of the lake is ideally suitable for presence of not more than 15, 000 fish. However, the number of the fishes were in lakhs. The administration tried to shift thousands of fish in other water-bodies and rivers but didn’t succeed in solving the problem. The report had also pointed out that the township lacks proper drainage system and all domestic wastewater and rainwater ends up in the sacred lake. The catchment slope of the lake is such that all rainwater flows right into it.
In May 2016, again thousands of fish were choked to death due to rise in water toxicity level. The administration stood helpless and did nothing more than burying the the dead fish. Administration didn’t bothered about this grieve crisis the lake had been facing.
Rewalsar Development Action Group, an NGO, raised the demand to take measures to prevent pollution of the lake. The NGO had also submitted a special report on conservation of the lake to the government. Save Rewalsar Lake campaign was also launched.
In April 2016, the National Green Tribunal has ordered ban on use of plastic around the lake, which was hardly followed. The NGT had pointed out complete failure of government to protect the lake. The tribunal had constituted a four-member high-level committee comprising of Secretary, HP Pollution Control Board the Secretary, Environment, and Secretary, Irrigation and Public Health. The committee was supposed to submit a comprehensive report over possible solutions for the restoration of original condition of the lake. God knows what happened to that report and the committee.
In June 2016, the issue of alarming degradation of the lake was again raised by the locals and the NGO. The community was still pleading for sewerage system and measures to prevent flood-water and domestic waste-water from draining into the lake. When an engineer of the Pollution Control Board, RK Nadda, was asked about the matter, he had simply refused to comment. District administration had told media that it’s seeking funds from the government. Again, there were only problems but no solution.
In March 2017, the Rewalsar Development Action Group approached the Chief Secretary, VC Pharka and the Deputy Speaker, Jagat Singh Negi requesting intervention to save the lake. President and Secretary of the Group briefed them about the plight of the lake and need to remove rising siltation. They again pleaded for the sewerage system.
A research study by the Wadia Institute of Himalayan Geology (WIHG), Dehradun and Physical Research Laboratory, Ahmedabad tittles “Rapid sedimentation history of Rewalsar Lake, Lesser Himalaya, India during the last fifty years…”
The study carried out using Pb and Cs dating on the top 2 meter (below lake floor) core of the lake. They found an average sedimentation rate of 3.35 cm/year during the last 50 years which is found to be the highest in comparison to the other lakes in the north-western Himalayan region.
The study concludes,
“During 1995 to 1963 AD, the Rewalsar Lake experienced a rapid sedimentation rate of 3.92 cm/year while it reduced to 2.78 cm/year after 1995 AD. At the Rewalsar Lake, the natural parameters, such as lithology, catchment area and slope, rainfall, etc. do not appear to be the limiting factors controlling the rate of sedimentation.”
The study further added,
“Rather, human interference, in terms of civil constructions and growth of township in the lake catchment area appears to be the most plausible factor controlling the sedimentation rate during the past fifty years.”
The study also said that,
“The present rate of sedimentation in the Rewalsar Lake, 3.92 cm/year, was still much higher than that of the other north-western Himalayan lakes which is less than 1 cm/year.”
“An early action plan is required to be followed up by the concerned authority to arrest the extremely higher sedimentation rate Rewalsar Lake and to protect the water body from faster degradation,” further suggested the study.
As we know, on April 17, locals were shocked to see sudden change in the color of the lake water. It turned muddy and suggested possible contamination. In next two days, thousands of fish were seen struggling to breath as soluble oxygen levels dropped to critical 0.8%. Aquatic life requires minimum level of 4-15 mg/L to support aquatic life (Fish). Thousands of fish died in next couple of days. The administration had to collect the dead fish and dispose of them to prevent health hazard.
Nearly, 5000 fish were rescued by shifting to other water bodies, claimed the administration. For media, the reason for mass death of the fish was low-level of oxygen. However, no one commented about the reason behind depletion of oxygen levels. Now, a ban has been imposed on feeding the fish and shopkeepers are directed not to sell fish-feed. Public is prohibited to visit the lake due to health hazards.
The government has again formed a committee to examine the issue of possible adverse effects on the natural aquifer and assess the chances of possible contamination of water. Committee is supposed to submit a report regarding the whole situation in detail, pinpoint reasons for fish mortality and suggest remedial measures.
The committee will be headed by Divisional Forest Officer, Mandi and Environment Engineer, HPSPCB, Bilaspur, Assistant Director, Fisheries, Mandi will be is members while Shri Kamraja Kaisth, Principal Scientific Officer-I, State Council for Science, Technology and Environment as its Member Secretary.
Additional Chief Secretary Environment, Science and Technology Shri Tarun Kapoor said the committee will assess and will submit its report to the Government within seven days.
Watch: An interesting case of leopard sighting in Shimla’s Dhanda locality
Shimla: People of Dhanda, a sort of suburb near the Totu in Shimla city, on Saturday found a leopard roaming around in their neighborhood in broad daylight. Leopard sightings in Himachal Pradesh are not unusual and Shimla is no exception. After all Himachal has 65 percent forest cover, as per official statistics.
However, this leopard was behaving like a stray dog that is used to living among humans. The big cat was not responding to the noises made by the people to scare off the animal.
The animal was not aggressive or afraid.
The leopard casually walked onto an under-construction floor of a residential building.
Luckily, the people did not harm the cat at all. In other parts of India, animals like leopard pay with their lives for straying into a human habitat. The people beat them to death with sticks and stone pelting.
But here, in Shimla, people informed the forest department about it, which was the right thing to do. Meanwhile, they just tried to scare it off so that it returns to the jungle. The people were discussing why the animal was behaving in an unusual way.
The people deserve appreciation for it because in most cases these animals revert as a defense to any sort of assaults by humans.
A resident posted some pictures and two videos of the incident. One of the video showed the animal roaming inside the residential locality. The other one showed the forest officials carrying the leopard on a stretcher and the crowd including kids following them.
They speculated it might have escaped from a zoo, which is why it was accustomed to human presence.
They spotted some wound on leopard’s body and assumed that perhaps the cat was injured.
The wildlife wing of the forest department arrived at the scene (this time with tranquilizer guns) and spotted the leopard in nearby bushes.
The animal was carried to the Rescue and Rehabilitation Centre situated in Tutikandi. It was identified as a seven-months-old female. It is not clear how it happened to stray into the locality.
The matter also pertains to the critical issue of man and animal conflict due to depletion of natural habitat. HW will try to get hold of the vet on Monday for a follow up.
Pollution killed 25 lakh people in India in one year – highest in the world: Report
Applying similar legislation and regulation from high-income countries to low- and middle-income countries could help to improve and protect health as countries develop.
While the leaders of the ruling political party are trying to politicize the firecracker ban imposed in Delhi by the Supreme Court, India has achieved another milestone – highest number of deaths due to various kinds of pollutions.
The Lancet Commission on Pollution and Health released its report on October 19. As per the report, air pollution is the biggest killer of all.
The report said out of total 6.5 million (65 lakhs) deaths reported worldwide, 28% occurred only in India. Air pollution mainly resulted in diseases such as heart disease, stroke, lung cancer, and COPD.
Almost all (92%) pollution-related deaths occur in low- and middle-income countries.
The findings of the say that in 2015, pollution killed about 2.5 million (25 lakhs) people. China reported the second highest number of deaths at 1.8 million (18 lakhs) during the same year.
It implies that air pollution kills doubt the number of people killed by AIDS, tuberculosis and malaria combined.
The next largest risk factor was water pollution the caused gastrointestinal diseases and parasitic infections.Workplace pollution including exposure to toxins and pneumoconiosis in coal workers, bladder cancer in dye workers, and asbestosis, lung cancer, mesothelioma, and other cancers in workers exposed to asbestos.
Finally, lead pollution resulted from high blood pressure, renal failure, and cardiovascular disease caused by lead in adults.
As per the report, human activities, including industrialisation, urbanisation, and globalisation, are all drivers of pollution.
Types of pollution associated with industrial development, such as ambient air pollution (including ozone), chemical, occupational pollution and soil pollution, have increased from 4.3 million (9.2%) in 1990 to 5.5 million (10.2%) in 2015 as countries reach higher levels of development.
The greatest impacts occured in countries that are currently undergoing rapid development and industrialisation – with pollution responsible for up to one in four deaths in the most severely affected countries (such as in India, Pakistan, China, Bangladesh, Madagascar and Kenya).
As countries develop and industrialise, the type of pollution and the related health problems they face change.
For example, water pollution and household air pollution are more common in early stages of industrial development, causing higher rates of pneumonia and diarrhoeal diseases in low- and middle-income countries.
Economic costs of pollution
The costs of pollution-related death and disease are also highly concentrated in developing regions imposing vast costs on national budgets – equivalent to around 1.3% GDP in low-income countries, compared to around 0.5% GDP in high-income countries, and 0.13% GDP globally. Healthcare spending on pollution-related diseases also disproportionately affects lower income countries – accounting for an estimated 7% of health spending in middle-income countries each year, and 1.7% annual spend in high-income countries.
Welfare losses due to deaths and disease from pollution equate to US$4.6 trillion each year (equivalent to 6.2% of global economic output). Proportionately, low-income countries pay 8.3% of their gross national income to pollution-related death and disease, while high-income countries pay 4.5%.
The environmental injustice often violates these people’s human rights.
Pollution, poverty, poor health, and social injustice are deeply intertwined. Pollution and related diseases most often affect the world’s poor and powerless, and victims are often the vulnerable and the voiceless. As a result, pollution threatens fundamental human rights, such as the right to life, health, wellbeing, safe work, as well as protections of children and the most vulnerable
Says Commission author Karti Sandilya, Pure Earth, USA.
In order to tackle pollution, we must prioritise it as an issue that affects us all, integrating it into health planning, and increasing funding to allow more research into pollution, such as monitoring pollution and its effects, and developing ways to control pollution,
says Commission co-lead, Richard Fuller, Pure Earth, USA.
Pollution can be eliminated, and pollution prevention can be highly cost-effective – helping to improve health and extend lifespan, while boosting the economy. This has been seen in high-income and some middle-income countries where legislation has helped to curb the most flagrant forms of pollution, and has led to cleaner air and water, lower blood lead concentrations, removal of hazardous waste sites, and less polluted and more liveable cities, the report further said.
The report suggest that pollution is not the inevitable consequence of economic development, and applying similar legislation and regulation from high-income countries to low- and middle-income countries could help to improve and protect health as countries develop.

HP Polls 2017: EC directs parties to use eco-friendly & biodegradable material for publicity
Shimla: With the announcement of the polling and counting date for the General Elections to the Legislative Assembly of Himachal Pradesh would come an environmental menace – waste of publicity material left by party workers during campaigning period. Use of flex boards would be an suitable example.
Considering the fact that the public, administration, and the politicians are least concerned about environmental or visual pollution, it was necessary that the Election Commission interfere here.
In its notification issued regarding the schedule for the elections, the Election Commission of India has included separate direction to all the political parties, contesting candidates and their authorized agents etc. to desist from utilizing environmentally hazardous materials like plastics, polythene etc for the preparation and usage election-related publicity materials.
The EC has directed them to use eco-friendly and bio-degradable substances for preparing election campaign or publicity material.
The EC has directed the DEOs and ROs to emphasize the importance of environment protection and preservation during the meetings with the political parties and contesting candidates. They were also asked to ensure that the the political parties adhere to the instructions of the Commission with regard to the usage of non-eco-friendly materials.
The Commission has directed all the CEOs to instruct all the political parties in their respective states regarding the usage of eco-friendly and biodegradable materials.
The concern of the Commission about the long-term deleterious impact of materials like plastics, polythene etc on the life-giving and life-sustaining environment is worth appreciable provided it is actually followed.
The political parties and their leaders bear the moral and ethical duty of passing instruction to their party-workers to adhere to the EC directions and help keep Himachal clean.
