Current Affairs Quiz - April, 2024

Notes:
The Eco-Niwas Samhita (ENS) introduced the Residential Envelope Transmittance Value (RETV), a metric measuring heat transfer in buildings. It’s a Residential Energy Conservation Building code by the Bureau of Energy Efficiency (BEE), setting standards for energy-efficient residential buildings. ENS 2018 (Part 1) focuses on envelope designs, while ENS Part 2 (ENS 2021) addresses code compliance and electromechanical systems. Lower RETV values lead to cooler indoor environments and decreased energy usage, aiming for an RETV of 15W/m² or less for optimal efficiency and comfort.

Notes:
Adani Ports and Special Economic Zone (APSEZ) has acquired a controlling 95% stake in Gopalpur Port, Odisha, solidifying its position in the ports and logistics sector. Valued at Rs 3,350 crore, the deal includes an equity value of Rs 1,349 crore and an enterprise value of Rs 3,080 crore. Previous majority stakeholders, Shapoorji Pallonji Group (SP Group) and Orissa Stevedores Ltd (OSL), held 56% and 44% stakes respectively. Gopalpur Port boasts a capacity of 20 MTPA and strategic location in Ganjam district.

Notes:
Adani Total Energies Biomass Limited (ATBL), a subsidiary of Adani Total Gas Limited (ATGL), has commissioned the first phase of Barsana BioGas plant in Mathura, Uttar Pradesh. The project, developed in three phases, will have a total capacity of 600 tonnes per day, producing 42 tonnes per day of Compressed Biogas (CBG) and 217 tonnes per day of organic fertilizer. It’s set to be India’s largest agri-waste-based bio-CNG plant, costing over ₹200 crore, utilizing advanced anaerobic digestion technology for sustainability and reducing greenhouse gas emissions.

Notes:
The International Energy Agency (IEA) recently released its 2023 Clean Energy Transitions Programme report. Established in 2017, the program aims to accelerate global progress towards a net-zero energy system, aligning with the Paris Agreement and UN Sustainable Development Goals. IEA, founded in 1974 amidst an oil crisis, operates within the OECD framework, collaborating with governments and industries worldwide. With 31 member countries and stringent criteria for candidacy, it focuses on shaping a secure, sustainable energy future.

Notes:
The forest department is eradicating Senna spectabilis, a highly invasive tree, from Mudumalai Tiger Reserve (MTR). Originally introduced as ornamental trees by private estates, the Madras High Court ordered their removal due to ecological impact on local reserves. Belonging to the legume family, native to South and Central America, it’s also known as golden wonder tree for its bright yellow flowers. Despite medicinal uses, including treating ringworm and food-borne pathogens, its removal is necessary for preserving local ecology.

Notes:
India’s Government e-Market (GeM) portal ranks as the world’s third-largest e-commerce platform for public procurement. GeM’s CEO PK Singh reported a gross merchandise value (GMV) exceeding Rs 4 lakh crore, doubling from the previous fiscal year. Launched in 2016, GeM facilitates transactions between government institutions and vendors, driving digital inclusion. The platform recorded Rs 2.01 lakh crore in orders for the last fiscal year, showcasing its significant growth trajectory.

Notes:
Researchers have found evidence of ozone on Jupiter’s moon Callisto, revealing insights into chemical processes on icy celestial bodies. The study focuses on the chemical evolution of “SO2 astrochemical ice,” composed of sulfur dioxide under ultraviolet irradiation. Analysis of UV absorption spectra of irradiated ice samples unveiled a distinct ozone formation signature. Callisto’s stable surface suggests it may harbor subsurface oceans or potential habitats, making it a potential candidate for extraterrestrial life.

Notes:
Natural gas is often termed a ‘bridge fuel’ aiding countries in transitioning from coal and oil to renewable energy. As society shifts towards cleaner energy, bridge fuels like natural gas aim to minimize environmental impact. Debates center on the duration and source of this transition. While natural gas emits less greenhouse gases, its role as a bridge fuel also hinges on factors like enhancing energy independence and reducing pollution costs.

Notes:
Recently, a destructive tornado hit Mainaguri, Jalpaiguri district, West Bengal, leaving five dead and over a hundred injured within its 10-minute rampage. Tornadoes, though rare, afflict India’s eastern regions like West Bengal, Odisha, and Jharkhand, especially pre-monsoon. A 2016 study by India Meteorological Department noted increased tornado activity in Bengal, with fatalities. Rising occurrences in India are attributed to factors like warming Bay of Bengal and unusual wind patterns.

Notes:
The World Bank’s ‘South Asia Regional Update: Jobs for Resilience report’ highlights that the region, including India, isn’t leveraging its demographic dividend due to insufficient job creation. While projecting a robust 6.0-6.1% growth for 2024-25, South Asia’s output surpasses other emerging markets, largely driven by India. However, private investment remains weak, posing downside risks to growth. The report emphasizes the need for addressing underlying vulnerabilities to sustain growth in the region.
