UPSC DAILY CURRENT AFFAIRS (17TH AUGUST, 2024) India need to create close to 8 million new jobs Syllabus: GS 3/Economy In News In the recently released Economic Survey, the Chief Economic Advisor estimated that India needed to create close to 8 million new jobs each year for the coming decade. Status India has been one of the brightest spots when it comes to GDP growth rates. India is doing extremely well in terms of its growth numbers. At 7% growth for this fiscal year makes India the fastest growing major economy in the world, and that contributes about 17% to global growth Main Challenges Inflation: Inflation is stabilizing but still needs careful management to avoid adverse economic effects. Geopolitical Tensions: Conflicts, particularly in the Middle East, could affect commodity prices, such as oil. Political Uncertainty: Numerous elections globally this year may bring policy uncertainty affecting growth. Medium-Term Growth: Projected global growth rates are weak compared to historical averages, necessitating structural reforms. The dollar’s dominance is due to the strength of U.S. institutions, open capital markets, and network effects. Impact of Artificial Intelligence (AI) on Employment About 25% of Indian workers are exposed to AI, with mixed effects on different sectors. AI can help address skill shortages, improve public finance, and enhance educational methods. But certain sectors, like call centres, may see reduced demand for human labour due to AI. Related steps Flexible inflation targeting has generally been successful globally by anchoring inflation expectations and improving credibility. India’s Experience : Since adopting inflation targeting in 2015, India has seen more stable inflation, although challenges remain.\ India is experiencing robust GDP growth, contributing significantly to global growth. Suggestions and Way Forward Encouraging corporate investment and flexible labour markets can aid broad-based growth and job creation. Improving ease of doing business and reducing trade restrictions are vital. Focus on education, skilling, and raising productivity in agriculture is essential for long-term growth. Improving macroeconomic and financial stability, and currency convertibility, benefits countries regardless of whether their currency becomes dominant. With continued reforms, India could sustain and possibly enhance its growth, but job creation is crucial. India needs to create 60 to 148 million new jobs by 2030, requiring broad-based growth across sectors.

Regenerative Agriculture: APCNF is more than just a farming technique; it’s a regenerative approach. It addresses the core challenges faced by farmers, including high-cost chemical farming, soil degradation, biodiversity loss, and water scarcity. Core Success Factors The core success factors that enable scale, replication, and sustenance are as follows: Positive Impact Livelihoods: APCNF positively impacts farmers’ livelihoods by reducing input costs and enhancing yields. Climate Resilience: It’s climate-resilient, which is crucial in an era of changing weather patterns. Food Security: Citizens benefit from improved food and nutrition security. Environment: APCNF contributes to environmental restoration and mitigates climate change. Small Satellite Launch Vehicle (SSLV) Syllabus: GS3/Science and Technology Context The Indian Space Research Organisation (ISRO) successfully launched the third developmental flight of the Small Satellite Launch Vehicle (SSLV) from the Satish Dhawan Space Centre. About The SSLV-D3 placed the Earth observation satellite EOS-08 precisely into orbit. It also marks the completion of ISRO/Department of Space’s SSLV Development Project. NewSpace India Limited (NSIL), ISRO’s commercial arm, and India’s private space industry can now produce SSLVs for commercial missions. What is an SSLV? It is a three-stage Launch Vehicle configured with three Solid Propulsion Stages. It also has a liquid propulsion-based Velocity Trimming Module (VTM) as a terminal stage, which can help adjust the velocity as it prepares to place the satellite. Significance: Essentially, the aim behind SSLVs is to produce low-cost launch vehicles with short turnaround times and minimal infrastructural requirements. The SSLV can launch satellites weighing up to 500kg and accommodate multiple satellites. Before SSLVs, smaller payloads had to be sent into Space using other launch vehicles carrying multiple, bigger satellites. They depended upon the launch schedules of those satellites. Launch Vehicles Launchers or Launch Vehicles are used to carry spacecraft to space. India has three active operational launch vehicles: Polar Satellite Launch Vehicle (PSLV), Geosynchronous Satellite Launch Vehicle (GSLV), Geosynchronous Satellite Launch Vehicle Mk-III (LVM3). PSLV: PSLV has been a versatile launch vehicle deployed for launching all the three types of payloads viz. Earth Observation, Geo-stationary and Navigation. It has got highest success rate and considered as work horse of ISRO. GSLV with indigenous Cryogenic Upper Stage has enabled the launching up to 2 tonne class of communication satellites. The LVM3 is the next generation launch vehicle capable of launching 4 tonne class of communication satellites and 10 tonne class of payloads to LEOs. The vehicle was developed with completely indigenized technologies including the C25 cryo stage. The launch vehicle has a track record of all successful launches even from the first development flight. The Human rated LVM3 is identified as the launch vehicle for Gaganyaan mission, which is named as HRLV. Threat to Aravali Range Syllabus: GS3/Environment Context The Aravali range is facing a severe threat from illegal mining, deforestation, and human encroachments, which have led to environmental degradation as well as depletion of groundwater reserves in the region. About The destruction of the hills has also led to loss of vegetation and soil cover, upsetting the area’s biodiversity, according to a scientific study on the land use dynamics of the Aravali range post-1975, published in the journal, Earth Science Informatics. Aravali Range With a length of 692 km and a width variation of 10 km to 120 km, Aravali forms an ecotone zone between Thar desert and the Gangetic plain, in a semi-arid environment. The range comprises over 500 hillocks, and the altitude of its highest peak, Guru Shikhar in Mount Abu. Rajasthan occupies 80% of the world’s oldest hill range, while other States — Haryana, Delhi, and Gujarat — have 20% share in the terrain. The mountain range is characterised by rugged hills, rocky outcrops, and sparse vegetation, and it plays a crucial role in the region’s ecology and hydrology. The Aravallis serve as a natural barrier against desertification, and helps regulate the climate, supports diverse ecosystems, and acts as a watershed for several rivers, including the Sabarmati, Luni, and Banas. Concerns Decrease in Forest Area: The Aravali range had recorded a change in the forest area significantly. From 1999 to 2019, the forest area decreased up to 0.9% of the total area, which is 75,572.8 sq. km. Increase in Mining Area: The mining area increased continuously from 1.8% in 1975 to 2.2% in 2019. Jaipur, Sikar, Alwar, Ajmer, Bhilwara, Chittorgarh, and Rajsamand districts have intensive mining activities. High rates of carbon flux Regions in upper and lower Aravali range had high positive rates of carbon flux as they received high rainfall and had protected areas. Carbon flux refers to the amount exchanged between carbon stocks over a specified time, as it records the movement of carbon between land, oceans, atmosphere, and living beings. The southern part was greener than the middle and upper parts because of the presence of more protected regions and less populated areas with minimum chances of anthropogenic disturbances. Way Ahead The Aravali range’s significance for conserving biodiversity, human livelihoods, desertification protection, and ecosystem services is critical. A comprehensive light detection and ranging (LiDAR)-based drone survey for the Aravali region is necessary. The LiDAR survey targets an object or a surface with laser and measures the time for the reflected light to return to the receiver. The survey is widely used in remote sensing to examine the surface of the earth and its objects with 3D dimensions. It will facilitate the identification and mitigation of illegal mining activities and enable authorities to take prompt enforcement actions to curb environmental degradation. Establishment of an independent Aravali Development Authority, comprising experts from diverse fields, would help devise and implement strategies for the sustainable preservation of the hill ecosystem. Besides, a ban on all forms of mining within the Aravali region would safeguard the remaining hills from further depletion and exploitation and preserve their ecological balance and biodiversity. FACTS IN NEWS Nord Stream Gas Pipeline Syllabus:GS2/Effect of Policies and Politics of Countries on India’s Interests Context Almost two years after bombing of the Nord Stream pipelines under the Baltic Sea, it remains unclear who sabotaged the pipes. About the Nord Stream Pipeline Nord Stream is a twin pipeline system, a subsea export gas pipeline that runs under the Baltic Sea carrying gas from Russia to Europe, built and operated by Nord Stream AG. Source: Bovanenkovo oil and gas condensate deposit in Western Siberia, and runs from Vyborg, Russia to Lubmin near Greifswald, Germany. It crosses the Exclusive Economic Zones (EEZs) of Russia, Finland, Sweden, Denmark and Germany, as well as the territorial waters of Russia, Denmark, and Germany. Nord Stream 1, completed in 2011 (From Vyborg in Leningrad to Lubmin near Greifswald, Germany). Nord Stream 2, completed in September 2021 (From Ust-Luga in Leningrad to Lubmin). Importance For Europe Europe’s dependence on Russia: For Natural gas (around 40% of its gas comes from Russia, ↓ domestic gas production). No easy replacements: No infrastructure to import LNG from exporters like Qatar and the U.S. European Green Deal: To phase out of Nuclear & Coal-based energy, increased dependence on Russian Gas. Industrialist’s Investment: Pressurise the govt. to go ahead with Nord Stream. Economic impact: Gas used for factories, offices and power generation. Importance For Russia Part of Major Budget Chunk: 40% of its budget comes from sales of gas and oil. Bypass transit countries: Cuts operating costs by doing away with transit fees & delivering important European customers. Increases Europe’s dependence on Russia.

Cyanide Sensor Syllabus :GS 3/Science and Tech In News A team led by Dr. Ravi Kumar Kanaparthi at Central University of Kerala has developed a highly sensitive and selective cyanide sensor. About the sensor Cyanide is a potent toxin found in plants, fruits, and microorganisms, with strict WHO guidelines limiting its concentration in potable water to below 0.19 mg/L due to its lethal effects. The new sensor aims to enhance safety by detecting toxic cyanide at low concentrations in drinking water and food products. The new sensor material changes color from yellow to colorless upon detecting cyanide, providing a clear visual indication of its presence. The sensor specifically detects cyanide without interference from other ions, ensuring accuracy. Importance : The sensor’s relevance is underscored by a recent cyanide poisoning incident in Idukki district, where 13 cows died from cyanide toxicity after consuming tapioca hulls. The sensor is expected to play a crucial role in preventing cyanide-related deaths and ensuring public safety globally. Californium Element Syllabus: GS3/ Science and Technology Context The police in Bihar’s Gopalganj seized 50 grams of the highly radioactive metal Californium. About Californium is a silvery-white synthetic radioactive metal with the atomic number 98 on the periodic table. It was first synthesized in 1950 at Berkeley, California, from where it derives its name, by bombarding curium with alpha particles. Californium is a very strong neutron emitter and is used in portable metal detectors for identifying gold and silver ores, to help identify water and oil layers in oil wells, and detect metal fatigue and stress in airplanes. Extremophile Syllabus: GS3/ Science and Technology Context Recently scientists found bacterial communities, known as Extremophiles, living in microwave ovens that survive repeated rounds of radiation. About Extremophile Microbes that live in extreme natural conditions are called extremophiles. Microbes adapt to extreme environments by incorporating unique biological and biochemical processes. Survival Mechanism Researchers believe that life began on the earth in an extreme environmental niche, in the form of an extremophile, before spreading and adapting to more temperate ecosystems. Extremophile microbes have multiple sets of proteins, each customized for life in a specific environmental niche. They activate each set depending on the conditions around them and what they need to survive. Green Tug Transition Program (GTTP) Syllabus: GS3/Infrastructure Context The Union Minister of Port Shipping and Waterways, launched the Standard operating procedure (SOP) for Green Tug Transition Program (GTTP) in New Delhi. Green Tug Transition Program (GTTP) The GTTP is designed to phase out conventional fuel-based harbor tugs operating in Indian Major Ports and replace them with green tugs powered by cleaner and more sustainable alternative fuels. Under Phase 1 of the GTTP four Major Ports—Jawaharlal Nehru Port Authority, Deendayal Port Authority, Paradip Port Authority, and V.O. Chidambaranar Port Authority—will procure or charter at least two green tugs each. The goal of the GTTP is to convert at least 50% of all tugs into Green Tugs by 2030 and to have Green Tugs operating at all major ports. Malabar Tree Toad (MCTT) Syllabus: GS3/ Environment Context According to a study, Climate change may decrease the distribution range of the Malabar Tree Toad by up to 68.7 percent of the current estimated distribution in India’s protected areas (PAs). About MTT is a species of toad endemic to Western Ghats of India. It is the only species in the monotypic genus Pedostibes, also known as Asian tree toads. It was first discovered in 1876 and the species was not sighted for more than 100 years. It was later rediscovered in 1980 at Silent Valley National Park in Kerala. Characteristics: It is a slender frog with a moderate-sized head. The snout is pointed and the lores are vertical. Females are larger than males. IUCN Status: Endangered Silent Valley National Park– It is located in the Nilgiri hills, Kerala.– The Bhavani River, a tributary of the Kaveri River, and Kunthipuzha River, a tributary of Bharathapuzha river, originate in the vicinity of Silent Valley. – The park is home to the birds like, Crimson-backed sunbird, Yellow-browed bulbul, Black bulbul, Indian white-eye, and Indian swiftlet. Prokaryotes Syllabus: GS3/Environment Context Scientists found prokaryotes are remarkably resilient to climate change – and as a result, could increasingly dominate marine environments. About Prokaryotes: The world’s oceans are home to microscopic organisms invisible to the human eye. The tiny creatures, known as “prokaryotes”, comprise 30% of life in the world’s oceans. Prokaryotes include both bacteria and “archaea”, another type of single-celled organism. These organisms are thought to be the oldest cell-based lifeforms on Earth. They thrive across the entire planet – on land and in water, from the tropics to the poles. Concerns: This could reduce the availability of fish humans rely on for food, and hamper the ocean’s ability to absorb carbon emissions. Marine prokaryotes grow extremely fast – a process that emits a lot of carbon. In fact, prokaryotes to an ocean depth of 200 metres produce about 20 billion tonnes of carbon a year: double that of humans. Prokaryotic and Eukaryotic Cells The cell is the basic unit of life and forms the building blocks of all living organisms. It was discovered by Robert Hooke In 1665. Some cells have membrane-bound organelles and some do not. Depending upon the internal structure of the cell, two types of cells are found in an organism namely Eukaryotic and Prokaryotic. Prokaryotic cells are simpler and smaller in size, while eukaryotic cells are more complex and larger. Impact of Artificial Lights on Plants Syllabus: GS3/Environment Context Artificial lights that run all night, such as streetlights, can make leaves grow so tough that insects cannot eat them, which could threaten urban food chains, according to a new study. About The researchers wanted to examine how artificial lights impact the relationship between plants and insects. The researchers found no sign of insects munching on leaves in areas which were lit the brightest at night due to toughening of leaves. They also noted that artificial lights altered the levels of nutrients and chemical defence compounds in the leaves that were analysed. Concerns: Lower levels of herbivory imply lower abundances of herbivorous insects, which could in turn result in lower abundances of predatory insects, insect-eating birds, and so on. The decline of insects is a global pattern observed over recent decades.
