Kailash Mansarovar Yatra
Prelims (GS I) – Current events of National Importance
Mains (GS I) – Indian History and Culture
Why in News?
The resumption of the yatra was formally discussed for the first time at the Special Representatives meeting in Beijing, which has been suspended since 2020.
- Location - Lake Mansarovar, known locally as Mapam Yumtso, is a high-altitude freshwater lake near Mount Kailash in the Ngari Prefecture of the Tibet Autonomous Region (TAR).
- Both the lake and the adjacent high mountain are believed to be the home of Lord Shiva, are sacred in Hinduism, Buddhism, Jainism, and the Tibetan Bon religion.
- Yatra – Ministry of External Affairs organized the pilgrimage for Indians between the months of June and September each year.
- Pilgrims usually trek to Lake Manasarovar, and then circumambulate the nearby Mount Kailash.
- Eligibility - The journey usually took between 23 and 25 days, and was open to anyone holding Indian passports, displaying medical and physical fitness.
- Age - Between 18 - 70.
- The total cost of the yatra would be upwards of Rs 2 lakh.
- The two routes - There are two primary routes to reach Lake Mansarovar from India.
- Lipulekh Pass Route - Lipulekh pass lies at an altitude of 5,115 metres, on the border between Uttarakhand and TAR, near the trijunction with Nepal.
- It is an ancient passageway between the Indian subcontinent and the Tibetan Plateau, frequented by traders and pilgrims alike.
- While the Lipulekh pass route is the most direct way to get to Mansarovar from India, the lake is roughly 50 km from the border, the terrain makes the journey very challenging.
- Currently, this route entails roughly 200 km of hard trekking. Before 2020, it had been operational since 1981.
- Nathu La Pass Route - Nathu La pass lies at an altitude of 4,310 metres on the border between Sikkim and TAR.
- It is one of two mountain passes in the region, the other being Jelep La that have connected Sikkim and Tibet since ancient times.
- The route to Mansarovar from Nathu La is much longer in terms of distance lose to 1,500 km.
- But it is fully motorable, meaning pilgrims can make it all the way to the lake without any trekking. (They would only need to trekk 35-40 km for the circumambulation of Mount Kailash).
- This route became operational in 2015.
- On the Indian side, logistics were arranged by the Kumaon Mandal Vikas Nigam on the Lipulekh route, and the Sikkim Tourism Development Corporation on the Nathu La route.
- TAR authorities provided accommodation and logistics on the other side of the border.
- One could provide the preference of route during the registration process on the MEA portal.

Flue Gas Desulphurisation
A study commissioned by the Principal Scientific Adviser suggests the Union Environment Ministry should reverse its 2015 policy mandating FGD installation in all coal–fired plants.
- Flue Gas Desulphurisation (FGD) – FGD is a process used in fossil–fuel power plants to remove sulfur compounds, particularly sulfur dioxide (SO2), from exhaust emissions using absorbents.
- Wet Process Dominance –The wet process, often using lime or limestone slurry in a scrubber tower, is the primary FGD method for large power plants, achieving up to 95% SO2 removal.
- Why FGD is Necessary –Burning fossil fuels releases sulfur into the atmosphere as sulfur dioxide (SO2), a major air pollutant.
- Environmental Impacts of SO2 – SO2 contributes to acid rain, harming forests, water bodies, soils, and aquatic life, and also causes corrosion and weathering.
- Importance of SO2 Removal – Removing sulfur dioxide is crucial for creating a safe and clean environment by limiting toxic emissions
