over the past 50 years, the Himalayas have become less cold with substantiated decline in number of extreme cold days and cold nights due to global warming and climate change: Department of Water Resources, River Development and Ganga Rejuvenation

New Delhi: Majority of Himalayan glaciers analysed are melting or retreating at varying rates in different regions, the government has said. It has noted that melting glaciers due to any impact of climate change will not only severely affect the flow in Himalayan river system but will also give rise to natural disasters. The government’s response was given to a parliamentary standing committee looking at Glacier Management in the Country – Monitoring of Glaciers/Lakes, including Glacial Lake Outbursts, leading to Flash-floods in the Himalayan Region.

The parliamentary standing committee report was tabled in Lok Sabha on Wednesday (March 29).

Explaining the problem of incessant melting and retreating of Himalayan glaciers and the estimated volume loss of glaciers between the year(s), the Department of Water Resources, River Development and Ganga Rejuvenation said the Geological Survey of India has conducted studies on their melting by assessment of mass balance studies on nine glaciers and also carried out monitoring the recession or advancement of 76 glaciers.

Majority of Himalayan glaciers are observed melting/ retreating at varying rates in different regions, it said.

The department pointed out that melting glaciers due to any impact of climate change will not only severely affect the flow in Himalayan river system but will also give rise to disasters like Glacier Lake Outburst Flood (GLOF), glacier avalanche, landslide etc.

Asked about the other adverse consequences of melting glaciers, especially on the ecology of the Himalayas, the department said melting of glaciers may lead to shift of tree line in the Himalaya and may also cause change in phonological behaviour of plants.

It may impact the livelihoods of mountain people and downstream populations. Such changes may lead to negative impact on biodiversity conservation and ecosystem services of the Himalaya, it said. The parliamentary standing committee flagged the lack of data sharing on hydrological information with the neighbouring countries.

The Committee noted that there is no specific agreement or treaty with neighbouring countries for sharing of glacier-related data for large-scale modelling and runoff evolution.

The Committee said it is of the view that in order to devise a comprehensive and coordinated strategy that could effectively address both the risk of glacier-related outburst floods and water management challenges, regional cooperation is the need of the hour.

Since the threat posed by the melting/retreating Himalayan glaciers transcends the national boundaries of the Himalayan nations, the Committee is of the considered view that in order to formulate an effective and comprehensive response to the threat posed by melting of glaciers and for mitigating potential hazard situations, regional cooperation for seamless sharing of hydrological information / data on glacier movement / behaviour is very much warranted, it said.

The Committee, therefore recommended to the Department of Water Resources, River Development and Ganga Rejuvenation to take up the matter with the Ministry of External Affairs to have some kind of bilateral or multilateral agreement with neighbouring Himalayan countries for sharing of information and data on the changing state of glaciers and the threats posed by them.

Asked about the veracity of the fact that over the past 50 years, the Himalayas have become less cold with substantiated decline in number of extreme cold days and cold nights due to global warming and climate change, the department said as per information given by the Environment ministry the climate change studies exclusively over the Himalayas reported a consistent warming in the present climate.

Trend analysis of cold days and cold nights of 16 stations across J&K and Himachal Pradesh has revealed that for most of the stations, percentage number of warm days is increasing and number of cold days is decreasing.

Also, similar pattern of increase /decrease in percentage number of warm /cold nights is seen. The reduction of cold days is noted to be approximately two to six per cent within a 30-year period.

NDTV – Dettol have been working towards a clean and healthy India since 2014 via the Banega Swachh India initiative, which is helmed by Campaign Ambassador Amitabh Bachchan. The campaign aims to highlight the inter-dependency of humans and the environment, and of humans on one another with the focus on One Health, One Planet, One Future – Leaving No One Behind. It stresses on the need to take care of, and consider, everyone’s health in India – especially vulnerable communities – the LGBTQ populationindigenous people, India’s different tribes, ethnic and linguistic minorities, people with disabilities, migrants, geographically remote populations, gender and sexual minorities. In wake of the current COVID-19 pandemic, the need for WASH (WaterSanitation and Hygiene) is reaffirmed as handwashing is one of the ways to prevent Coronavirus infection and other diseases. The campaign will continue to raise awareness on the same along with focussing on the importance of nutrition and healthcare for women and children, fight malnutrition, mental wellbeing, self care, science and health, adolescent health & gender awareness. Along with the health of people, the campaign has realised the need to also take care of the health of the eco-system. Our environment is fragile due to human activity, which is not only over-exploiting available resources, but also generating immense pollution as a result of using and extracting those resources. The imbalance has also led to immense biodiversity loss that has caused one of the biggest threats to human survival – climate change. It has now been described as a “code red for humanity.” The campaign will continue to cover issues like air pollutionwaste managementplastic banmanual scavenging and sanitation workers and menstrual hygiene. Banega Swasth India will also be taking forward the dream of Swasth Bharat, the campaign feels that only a Swachh or clean India where toilets are used and open defecation free (ODF) status achieved as part of the Swachh Bharat Abhiyan launched by Prime Minister Narendra Modi in 2014, can eradicate diseases like diahorrea and the country can become a Swasth or healthy India.
