Lake Powell:

Lake Powell, one of the largest reservoirs in the United States, has fallen to its lowest level since it began filling, deepening concerns over the future of the Colorado River and the millions of people who rely on it.

• It is a huge man-made lake located on the Colorado River and stretches across parts of Utah and Arizona in the United States.
• The lake was created by building the Glen Canyon Dam, which flooded Glen Canyon.
• It’s the second-largest reservoir in the United States by volume (second only to Lake Mead).
• It is an oligotrophic reservoir, which means that nutrient concentrations and algal production are generally low. This often results in very clear-water conditions.
• The lake is also a major recreation area, known for magnificent sandstone canyons and rock formations.

INS Imphal: Students Visit

More than 200 students from Indian schools in Muscat recently visited the indigenously built warship INS Imphal while it was berthed at Sultan Qaboos Port in the Omani capital.

Rotating Detonation Engine:

India-based defence start-up D-Propulse announced that it had successfully demonstrated a rotating detonation engine at a Defence Research & Development Organisation facility in Hyderabad.

• Rotating Detonation Engine (RDE) is a type of propulsion system that differs from conventional gas turbines and ramjets in the way it uses fuel.
• Usually, engines use deflagration, which is a subsonic, steady way of burning fuel through a flame.
• On the contrary, an RDE uses detonation, wherein the fuel burns faster as rapid supersonic explosions rotate through the chamber of the engine.
• This rapid detonation produces more thrust for the same amount of fuel.
• This volume savings can be used to increase fuel and/or payload volume, providing potential range, speed, and affordability benefits compared to rockets, ramjets, and gas-turbines.
• These mechanically simple RDEs have no moving parts, making them less complex than gas turbine engines and therefore potentially lower cost and simpler to manufacture.

Supreme Court on Electoral Black Money:

The Supreme Court observed that removing the influence of black money from elections is a responsibility of the Election Commission of India (ECI).

• The Court held that the use of ill-gotten money can distort the free choice of voters and undermine democracy, rule of law and the electoral process. It also issued directions for time-bound investigation, reporting of seizures and speedy trials in election-related black money cases.
• The Supreme Court has placed greater responsibility on the ECI to curb black money in elections, directing time-bound investigations, seizure reporting, quarterly monitoring and speedy trials to protect free and fair elections.
• Electoral black money undermines voter autonomy, equality, transparency and democratic accountability. Stronger political-funding transparency, expenditure regulation, financial intelligence, state funding and judicial fast-tracking are needed to address the problem.

Key Directives Issued by the Supreme Court:

• Seized cash or assets must be reported within 24 hours to the District Magistrate, Additional District Magistrate or competent court, along with reasons showing a prima facie link with the suspected electoral offence.
• Investigating Officers should complete election-related FIR investigations within one year. Any delay must be justified and reported to the ECI.
• Investigating Officers must submit quarterly status reports on such cases to the ECI.
• Static Surveillance Teams detecting cash above Rs 10 lakh must forward the information to Income Tax authorities
• High Courts must ensure expeditious disposal of election-related black money cases, including through designated courts where required.
• Withdrawal of criminal cases against candidates relating to an election cycle requires approval of the concerned High Court
• The ECI and State Governments have been directed to submit compliance reports by 18th November 2026.

• The training will include field exercises, combat discussions, lectures, demonstrations and a culminating validation exercise.
• The contingents will also exchange operational experience and showcase contemporary equipment and technologies employed during joint operations.
• It will further reinforce the longstanding bilateral relations between the two nations.

Greenium and Sovereign Green Bonds:

India’s sovereign green bond market is gaining traction as strong investor demand has pushed green bonds to trade at a persistent greenium over comparable conventional government securities.

• The average greenium in the first half of FY27 reached its highest level since India began issuing sovereign green bonds in FY2022-23. The trend indicates that the market may be able to absorb a larger supply of green bonds in the second half of FY27.
• Greenium’ (green premium) refers to the lower yield (interest rate) that investors are willing to accept on a green bond that finance environmentally sustainable projects compared to conventional government securities.
• Since bond prices and yields move inversely, a lower yield means investors are willing to pay a higher price for green bonds, reflecting their preference for environmentally sustainable investments.
• Stable Greenium lowers the overall cost of borrowing for the government, allowing it to finance large-scale renewable energy, electric mobility, and adaptation projects needed to meet India’s Net Zero by 2070 targets economically.
• A consistent greenium spread demonstrates a maturing domestic green finance ecosystem and sustained investor confidence in the credibility of India’s green taxonomies and Environmental, Social and Governance (ESG) project evaluation.
• Sovereign Green Bond are government debt instruments introduced in the Union Budget 2022-23 to finance projects that support India’s transition towards a low-carbon economy.
• The funds raised are earmarked exclusively for eligible green projects, promoting transparency and accountability in their utilisation.
• The SGrB Framework is aligned with the International Capital Market Association (ICMA) Green Bond Principles (2021), strengthening the credibility and transparency of India’s sovereign green bonds.
• SGrBs are issued through a uniform price auction, are eligible for repo transactions, and can be traded in the secondary market.
• SGrBs are also eligible for Statutory Liquidity Ratio (SLR) purposes, allowing financial institutions to count them towards their mandatory SLR holdings.
• The Finance Ministry released India’s first Sovereign Green Bond (SGrB) Framework in 2022, specifying the projects eligible for funding.
• To strengthen credibility, the framework was validated by Norway-based CICERO, which rated it ‘Medium Green’ with ‘Good Governance’, indicating alignment with the International Capital Market Association (ICMA) standards.

Odisha Coastal Erosion:

Union Minister for Ports, Shipping and Waterways informed the Rajya Sabha that 28.3% of Odisha’s 564-km coastline is undergoing erosion, based on a long-term assessment (1990–2022) by the National Centre for Coastal Research (NCCR).

• Coastal erosion is the progressive wearing away and landward displacement of beach or dune sediments caused by hydrodynamic forces such as waves, tidal currents, storm surges, and littoral drift.
• In Odisha, the interaction between severe tropical cyclones in the Bay of Bengal and human-made coastal structures alters natural sediment transport, resulting in rapid shoreline retreat, coastal flooding, and the loss of inhabited land.

Data & Statistics on Coastal Erosion in Odisha:

• Overall Coastline Dynamics: According to the NCCR mapping of Odisha’s 564.14 km coastline, 28.3% is eroding, 54.1% is accreting (growing), and 17.6% remains stable.
• Worst Affected Districts: Jagatsinghpur is the most vulnerable, with 47.6% of its 55.8-km coastline eroding, followed closely by Ganjam (45.7%) and Kendrapara (45.0%).
• Other Impacted Stretches: Moderate to low erosion is recorded across Balasore (23.8%), Puri (10.2%), and Bhadrak (4.6%).
• Submergence of Inhabited Land: Rising sea levels and coastal land loss have already submerged 16 entire villages in Kendrapara district alone, displacing hundreds of families.

The Foreign Currency Non-Resident (Bank) — FCNR(B) Deposits:

The Reserve Bank of India (RBI) advanced the deadline for fresh Foreign Currency Non-Resident (Bank) [FCNR(B)] deposits to qualify for its special USD–INR forex swap window to August 31, 2026.An FCNR(B) deposit is a term/fixed deposit account maintained in approved foreign currencies by Non-Resident Indians (NRIs) and Overseas Citizens of India (OCIs) with authorized banks in India.Unlike rupee-denominated NRI accounts (such as NRE or NRO accounts), the funds are held entirely in foreign currency, eliminating foreign exchange conversion risk for the depositor.The FCNR scheme was originally introduced in 1975 (where the exchange risk was borne by the RBI/Government).To eliminate central fiscal liabilities, the revised FCNR(B) Scheme was launched in May 1993, under which commercial banks themselves maintain and manage foreign currency exchange exposure and liabilities. Governed under the Foreign Exchange Management Act (FEMA), 1999 and RBI Master Directions on Non-Resident Deposits.Aim is to attract stable, long-term foreign currency capital into the Indian banking system, reinforce India’s external Balance of Payments (BoP), bolster gross foreign exchange reserves, and provide non-resident Indians with a secure, tax-free, and exchange-risk-free investment avenue in India.
