Archives (PRELIMS & MAINS Focus) Netaji Subhash Chandra Bose Island Syllabus Prelims – Geography Context: The unchecked population growth of spotted deer (Chital) is creating problems in Netaji Subhash Chandra Boss Island. Background:- Introduced to the Andaman and Nicobar Islands for game hunting in the early 1900s by the British, the herbivore multiplied unchecked for years in the absence of large predators.It has become an “invasive” problem for the Union Territory’s authorities. About Netaji Subhash Chandra Bose Island Earlier Ross Island, now officially known as Netaji Subhash Chandra Bose Island, is an island of the Andaman Islands. The Island is situated three kilometres East of Central Port Blair. It belongs to the South Andaman administrative district, Andaman and Nicobar Islands. The Andaman and Nicobar Islands are strategically located in the Indian Ocean between the Indian mainland, Myanmar, and Indonesia, and are close to important maritime routes. The islands were first controlled by the Dutch, then by the British, and were taken over by the advancing Japanese military during World War II. The Azad Hind government was able to obtain de jure control of the islands from the Japanese by the end of 1943, and Subhash Chandra Bose arrived in Port Blair on December 29. Keeping in mind the historical significance of the Andaman & Nicobar Islands and to honour the memory of Netaji Subhas Chandra Bose, Ross Islands was renamed as Netaji Subhash Chandra Bose Dweep by Prime Minister during his visit to the Island in 2018. Neil Island and Havelock Island were also renamed Shaheed Dweep and Swaraj Dweep. All the three islands are major tourist spots.

Background: Big Indian commercial vehicle manufacturers such as Tata Motors, Volvo Eicher, and Ashok Leyland are doubling down on efforts to develop hydrogen-powered trucks and buses by ramping up research and development, and building manufacturing capacities. About Green Hydrogen : Hydrogen is colourless, and green hydrogen is ‘green’ only by virtue of the way it is produced, and the source of the energy used to manufacture it. Green hydrogen refers to hydrogen that is produced from the electrolysis of water — splitting it into hydrogen and oxygen — using an electrolyser powered by renewable energy.This is considered to be a virtually emission-free pathway for hydrogen production — it is ‘end-to-end’ green because it is powered by green energy, uses water as feedstock, and emits no carbon on consumption. Currently, most hydrogen produced for industrial consumption and applications is ‘grey’ hydrogen, which is produced from natural gas through energy-intensive processes, and has high carbon emissions.Except for a difference in the production pathway and emissions, green hydrogen is essentially the same as grey — or hydrogen categorised by any other colour. Challenges to the large-scale use of green hydrogen in the transportation sector: The foremost among challenges is the prohibitive cost of production, followed by challenges of storage and transportation at scale. Green hydrogen-powered vehicles are not yet seen as a suitable alternative to four-wheel battery electric vehicles (BEVs) due to challenges arising from fuel costs and building supporting infrastructure. Hydrogen is extremely flammable, which means that special care would be needed in handling the fuel at retail stations compared to diesel, petrol, or even CNG. Robust and fool-proof handling and safety standards need to be developed before pushing large-scale adoption. Currently, most cylinders manufactured in India are designed to carry compressed natural gas (CNG). But hydrogen is stored at a much higher pressure, and CNG cylinders cannot carry hydrogen. For cylinders to carry a high mass of hydrogen, the carbon fibre needs to be stronger, which makes high-pressure hydrogen cylinders expensive. This is a key barrier to the adoption of hydrogen as a transport fuel. For the same reason, the existing natural gas pipeline infrastructure is also not seen as viable.

Background: These revisions reflect a deeper understanding of the Harappan civilization and its historical context, shedding light on their origins and societal structures. About RAKHIGARHI Rakhigarhi is an archaeological site located in Hisar, Haryana, and is recognized as one of the largest Harappan (Indus Valley Civilization) sites in the Indian subcontinent. Rakhigarhi is situated in the plains of the Saraswati River, about 27 km from the seasonal Ghaggar river. The site showcases continuity from the Harappan age to the present times. It is recognized for its extensive Harappan heritage, offering insights into ancient urban life and culture. Excavations were carried out at Rakhigarhi to study its evolution from 6000 BC (Pre-Harappan phase) to 2500 BC. In order to study the genetic history of the Harappans, DNA was extracted from the skeletal remains excavated at Rakhigarhi. Previous Year Question Q1. Which of the following characterizes/characterize the people of Indus Civilization? They possessed great palaces and temples. They worshipped both male and female deities. They employed horse-drawn chariots in warfare. Select the correct statement/statements using the codes given below: 1 and 2 only 2 only 1, 2 and 3 None of the statements given above is correct Source: Hindu DEMOGRAPHIC DIVIDEND Syllabus Prelims – Economy Context: The World Bank warned that South Asian nations run the risk of “squandering its demographic dividend” because job creation is not keeping up with the growth in the working-age population. Background: According to data in the report, between 2000 and 2023, When the working-age population grew by an average of 19 million per year, the region added 10 million employments annually on average. About DEMOGRAPHIC DIVIDEND: The United Nations Population Fund defines demographic dividend as “the economic growth potential that can result from shifts in a population’s age structure,
