{GS2 – Governance} Rural India’s Energy Crisis **

• Context (DTE): Despite expanded energy access, affordability, reliability, and local factors continue to limit actual energy security in rural India.

Key Dimensions of Rural Energy Insecurity

• Affordability Constraints: Over 10 crore LPG connections distributed, but over 50% households did not refill even once due to high refill costs.
• Rising Energy Burden: Rural Monthly Per Capita Expenditure on energy rose to ₹536 (13.8%) in 2022–23, up from ₹174 (12%) in 2011–12.
• Unreliable Electricity: Frequent power cuts and poor-quality supply reduce effective utilisation despite near-universal (~99%) electrification.
• Dependence on Biomass: ~46.7% rural households depend on firewood/crop residue; extremely high in states like Chhattisgarh (84.2%) and MP (72.5%).
• Health Risks: 56.1% rural households use solid fuels, and 94.8% rely on chulhas, leading to indoor air pollution.
• Low Income: Low and unstable incomes force households to prioritise cheaper energy options over cleaner alternatives.
• Infrastructure Gaps: Inadequate last-mile delivery, weak energy infrastructure, and regional disparities hinder consistent and reliable energy access.

Energy Security Initiatives in India

• PM-KUSUM: Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan provides solar pumps for farmers; reduces diesel dependency; offers additional income to farmers.
• Saubhagya Scheme: PM Sahaj Bijli Har Ghar Yojana aims for universal household electrification, focusing on ensuring last-mile connectivity to un-electrified rural households.
• DDUGJY: Deen Dayal Upadhyaya Gram Jyoti Yojana promotes rural feeder separation (agriculture vs domestic); enhances rural distribution infrastructure.
• GOBARdhan: Converts cattle dung & organic waste into biogas.
• PMUY: Pradhan Mantri Ujjwala Yojana LPG connections for BPL households; replaces biomass and firewood; reduces indoor air pollution and drudgery for women.

Way Forward for Strengthening Rural Energy Security

• Reliable Electricity Supply: Strengthen rural grid infrastructure, maintenance, and decentralised renewable systems (solar mini-grids).
• Clean Cooking Alternatives: Expand access to electric cooking, biogas, and improved cookstoves to reduce biomass dependence.
• Infrastructure: Improve distribution networks, refill availability, and rural energy services to ensure consistent access.
• Localised Solutions: Design policies based on local resource availability, income levels, and community needs rather than one-size-fits-all approaches.

{GS2 – Vulnerable Sections} High Maternal Mortality in India **

• Context (IE): A study published in The Lancet highlights challenges for India in achieving the SDG target of reducing Maternal Mortality Ratio.

• India contributes around 10% of global maternal deaths, though it has made one of the largest reductions globally.

Maternal Mortality Ratio in India

• India’s MMR declined from 508 (1990) to around 116 (2023), reflecting major improvements in maternal healthcare.
• As per the Sample Registration System (SRS), MMR reduced from 122 (2015–17) to 88 (2021–23).
• Data Gap: Differences in estimates exist, with UN estimates (~80) lower than SRS (~88).
• SDG Target: India aims to achieve MMR below 70 by 2030 under the SDGs.
• Interstate Disparities: States like Kerala & Tamil Nadu have low MMR, while Assam and Uttar Pradesh report higher levels, indicating regional inequality.
• Slowing Progress: Although MMR has declined, the rate of reduction has slowed, posing challenges for meeting SDG targets.

Causes of High Maternal Deaths

• Haemorrhage: Severe bleeding is the leading cause of maternal deaths due to delayed emergency care.
• Sepsis (Infections): Poor hygiene & delayed treatment during or after delivery can cause maternal death.
• Unsafe Abortions: Lack of access to safe abortion services results in complications and deaths from unsafe procedures.
• Anaemia and Malnutrition: Iron deficiency and poor nutrition weaken maternal health, increasing the risk of complications during pregnancy and childbirth.
• Hypertensive Disorders: Conditions like pre-eclampsia and eclampsia lead to complications such as seizures and organ failure.
• Delays in Healthcare Access: The “three delays”—delay in decision, reaching the facility, and receiving care significantly contribute to maternal deaths.

Way Forward to Improve Maternal Health

• Primary Healthcare: Improve access to quality antenatal, institutional delivery, and postnatal care, especially in rural and high-burden states.
• Focus on High-Burden States: Implement targeted interventions in Assam, Uttar Pradesh, and similar states through better infrastructure and monitoring.
• Prevent Major Causes: Ensure timely treatment of haemorrhage, hypertension, and infections through trained staff and emergency care.
• Improve Nutrition: Promote maternal nutrition, family planning, and awareness to reduce early pregnancies and improve maternal health.

{GS3 – IE} RBI Bans Non-Deliverable Derivative

• Context (IE): The RBI has banned banks from engaging in Non-Deliverable Derivative (NDD) contracts to curb rupee volatility.

• Objective: The ban aims to reduce speculative trading and stabilise the rupee, which was under pressure due to rising oil prices and global uncertainties.
• The ban is likely to reduce short-term volatility and strengthen the currency market. Following the ban, the rupee appreciated from below ₹95 to ~₹93/USD.
• The move aligns India’s forex practices with international accounting and regulatory standards.

Non-Deliverable Derivative

• A Non-Deliverable Derivative (NDD) is a financial contract where parties agree on an exchange rate, but no actual currency is exchanged.
• Cash Settlement: The contract is settled in cash (usually USD) based on the difference between the agreed and actual exchange rates.
• Offshore Market: NDDs are traded in offshore financial centres like Singapore & London outside India.
• Purpose: Used by investors for hedging currency risk or speculating on rupee movements.
• Impact on Rupee: NDD markets can influence exchange rate expectations and cause volatility, sometimes diverging from the domestic Market.

{Prelims – S&T} Genetic Basis of Seedlessness in Grapes *

• Context (PIB): Scientists from Agharkar Research Institute and Savitribai Phule Pune University have decoded genetic mechanisms behind seedlessness in grapes.

• Seedless grapes are preferred globally due to better taste, texture, & suitability for fresh consumption.
• Pollen Sterility: Seedlessness in grapes is mainly caused by pollen sterility due to genetic mutations.
• Reproductive Failure: Impaired pollen function prevents successful fertilisation, stopping seed formation.
• Resulting Mechanism: These genetic defects induce Parthenocarpy, resulting in seedless grapes.
• Significance: Findings will enable the development of molecular markers for faster breeding of improved seedless grape varieties.

{Prelims – S&T} New Ocean Floor Map Released Using SWOT Satellite Data

• Context (IE): NASA and the French space agency (CNES) have released a global ocean floor map using Surface Water and Ocean Topography (SWOT) satellite data.

• The satellite uses radar interferometry to measure ocean surface height with centimetre-level accuracy.
• Mechanism: Large underwater features like seamounts and abyssal hills exert stronger gravitational pull than their surroundings, creating subtle bulges on the ocean surface above.
• Output: NASA converts these surface height measurements into a map of the vertical gravity gradient.
• Ship-based sonar remains the most precise method for high-resolution ocean floor mapping.
