Mali’s Army Retakes Kidal: The Tuareg Question, Jihadist Insurgency and Russia’s Role in the Sahel

ImportantGS-II · IR — Africa, Effect of Policies of Other Countries · GS-I Places in NewsPrelims + MainsNews reports (Oct 2026)

Mali’s armed forces, supported by Russia’s Africa Corps, have reportedly re-entered Kidal after the Tuareg separatist Azawad Liberation Front (FLA) announced a “strategic withdrawal” following heavy air strikes. The town had fallen to separatists and the al-Qaeda-linked JNIM in April 2026.

◈ Basics First — Mali, the Sahel and the Tuareg

• Mali — a landlocked West African country, former French colony (independent 1960); capital Bamako; the Niger River runs through its centre.
• The Sahel — the semi-arid belt south of the Sahara, stretching from Senegal to Sudan; marked by drought, weak state presence and armed groups.
• Kidal — a desert town in the far north-east, near the Algerian border and the Adrar des Ifoghas massif; the political centre of the Tuareg demand for an independent “Azawad”.
• The Tuareg — a Berber-speaking, traditionally nomadic people spread across Mali, Niger, Algeria and Libya; they rebelled in 1963, 1990, 2006 and 2012.

Figure 1 — Mali and the Location of Kidal

Kidal lies about 1,500 km north-east of Bamako — closer to Algeria than to the capital. Base geography: Natural Earth 1:10m, public domain.

Static Background — A Conflict Timeline

• 2012 — a Tuareg rebellion declares “Azawad” independent; jihadist groups seize the north; a military coup in Bamako.
• 2013 — French Operation Serval (later Barkhane, to 2022) and the UN mission MINUSMA (2013–2023) deploy.
• 2015 — Algiers Peace Agreement with northern armed groups; Mali’s junta terminated it in January 2024.
• 2020 and 2021 — two coups bring a military government; ties with France rupture and Russian Wagner forces arrive, later replaced by the state-controlled Africa Corps (2025).
• November 2023 — the army first retook Kidal; separatists regained it in April 2026, before its recapture now.
• Alliance of Sahel States (AES) — Mali, Burkina Faso and Niger (2023), which left ECOWAS in January 2025.

Significance and India Angle

• Symbolic capital — control of Kidal is a test of the junta’s claim to territorial integrity; separatists retain mobility in the desert.
• Jihadist threat — JNIM (al-Qaeda) and the Islamic State Sahel Province exploit the conflict; the Sahel has become a leading region for terrorism deaths.
• Great-power shift — the exit of France and the UN, and the rise of Russia, reshape the region; reported civilian casualties from air strikes raise human-rights concerns.
• India — interests in the safety of Indian workers (three Indian nationals were kidnapped in western Mali in July 2025), counter-terrorism cooperation, development partnership through lines of credit and ITEC, and access to West African resources.

✎ Mains Practice Question

The Sahel has emerged as a hub of separatism, jihadist insurgency and great-power rivalry. Examine the factors behind instability in the region, with reference to Mali, and discuss its implications for India’s Africa policy. 15 marks · 250 words

ARIES-Led Global Study Tracks a Decade of Flickering in OJ 287, a Rare Binary Supermassive Black Hole System

ImportantGS-III · S&T — Space, Achievements of Indians in S&TPrelims + MainsPIB · Department of Science & Technology

A campaign coordinated by the Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital — 106 scientists from 18 countries and 48 institutions, using about two dozen telescopes — has produced the densest optical record of the blazar OJ 287 in 150 years, covering 2015–2025.

◈ Basics First — Black Holes, Quasars and Blazars

• Supermassive black holes (SMBHs) — of millions to billions of solar masses, sitting at the centres of most large galaxies.
• Active Galactic Nucleus (AGN) — a galactic centre where matter falling into the SMBH forms a hot accretion disc and can launch relativistic jets of plasma.
• Blazar — an AGN whose jet points almost directly at Earth; it shows strong, rapidly varying emission from radio waves to gamma rays.
• Binary SMBH — formed when galaxies merge; two black holes orbit each other and eventually coalesce, releasing gravitational waves.

Figure 2 — The Binary Black Hole Model of OJ 287

In the established model, the smaller black hole crosses the bigger one’s accretion disc twice per 12-year orbit, producing double-peaked flares. The illustration’s 18.35-billion-solar-mass primary comes from earlier orbital modelling; the new spectral estimate (≥3.89 billion) is far lower — a live scientific debate. Image as released with the PIB note; reproduced with credit for educational use.

Key Findings

• About OJ 287 — roughly 4 billion light years away; its 12-year double-peaked brightness cycle was identified in 1988 by Finnish astronomers using optical records going back to 1880.
• Data — the most extensive multiband optical time series of the object, supported by observations across the electromagnetic spectrum.
• Black hole mass — spectra from the Steward Observatory (USA), using the width of the [O III] emission line, put the central black hole at at least 3.89 billion solar masses.
• Science gained — tracking the relative positions of the two black holes, changes in brightness, spectrum and polarisation, and searching for emission from the smaller black hole.

▤ Institutions & Terms to Know

• ARIES, Nainital — autonomous institute of the DST; operates the 3.6-m Devasthal Optical Telescope, India’s largest optical telescope, and the International Liquid Mirror Telescope at Devasthal.
• Multi-messenger astronomy — studying one source through light, gravitational waves, neutrinos and cosmic rays.
• Gravitational waves — first directly detected by LIGO in 2015; LIGO-India (Hingoli, Maharashtra) was approved in 2023. Binary SMBHs are prime sources of the low-frequency waves sought by pulsar timing arrays, including India’s InPTA.

Why Nuclear Power Is Central to the Race for Permanent Moon Bases

ImportantGS-III · S&T — Space Technology · GS-II International TreatiesPrelims + MainsThe Hindu · Analysis

NASA plans to install a nuclear fission reactor near the Moon’s south pole by 2030, while Russia is developing a reactor for the China-led International Lunar Research Station (ILRS). Power for a semi-permanent base has become the first test of the US–China lunar race.

◈ Basics First — Why Not Solar?

• Lunar night — a location on the Moon gets about 14 Earth days of darkness at a time, and temperatures plunge far below freezing.
• South pole — attractive because permanently shadowed craters may hold water ice, but they receive no sunlight at all.
• Fission reactor — splits uranium nuclei to produce steady heat and electricity regardless of sunlight; NASA tested a small prototype (KRUSTY, 2018) under its Kilopower project.
• RTG (Radioisotope Thermoelectric Generator) — converts heat from the natural decay of plutonium-238; reliable but produces only hundreds of watts, suited to probes and rovers rather than bases.

The Legal Framework

• Outer Space Treaty (1967) — bans nuclear weapons in orbit and on celestial bodies and any national appropriation of the Moon, but does not prohibit nuclear power.
• UN Principles Relevant to the Use of Nuclear Power Sources in Outer Space (1992) — non-binding safety guidelines.
• Moon Agreement (1979) — declares the Moon the common heritage of mankind; few space powers have ratified it (India signed but has not ratified).
• Artemis Accords (2020) — US-led principles; provide for temporary “safety zones” to avoid harmful interference. India signed in June 2023. Critics fear such zones could become de facto territorial claims.

Significance and the India Angle

• Two blocs — the Artemis programme and the ILRS (China–Russia, 2021) are competing for the same resource-rich polar region; whoever establishes power infrastructure first gains a practical edge.
• Safety concerns — launch accidents, radiation shielding and disposal of spent fuel need international norms.
• India — Chandrayaan-3 landed near the south pole (August 2023); India aims to set up the Bharatiya Antariksh Station by 2035 and land an Indian on the Moon by 2040, making long-duration power technology strategically relevant.

Why Stubble Fires Keep Coming Back: Water Law, Procurement Incentives and the Measurement Problem

Core TopicGS-III · Environment — Pollution; Agriculture — Cropping Patterns, MSPPrelims + MainsThe Hindu · Full Context

Every October–November, burning of paddy straw in Punjab and Haryana worsens air quality across North India. The analysis argues that the practice persists because of a combination of groundwater law, assured procurement, free power and a narrow window between crops — and that official claims of a sharp decline rest on flawed measurement.

◈ Basics First — What Is Stubble Burning?

• Stubble — the lower stalks left in the field after harvest. Combine harvesters, in use since the late 1970s, leave about a foot of stubble.
• Scale — Punjab and Haryana together produce around 29 million tonnes of paddy straw a year.
• Harm — releases PM2.5, carbon monoxide, VOCs and carcinogens that form smog; burns away soil nitrogen, sulphur, phosphorus, potash, organic matter and moisture, raising fertiliser use for the next crop.
• Why it peaks in winter — calm winds and temperature inversion in the Indo-Gangetic plain trap pollutants near the ground.

The Root Causes

• Punjab Preservation of Sub-Soil Water Act, 2009 — to save groundwater, it barred paddy nursery sowing before 10 May and transplanting before 10 June. This pushed harvest to late October, leaving only a 10–15 day window before wheat sowing.
• The groundwater crisis — a 2009 NASA GRACE satellite study found that Punjab, Haryana and Rajasthan lost about 109 cubic km of groundwater in 2002–2008.
• Long-duration varieties — high-yield PUSA-44 (150–160 days) further squeezed the window.
• Incentive structure — assured MSP procurement and free or near-free farm power lock farmers into the water-intensive rice–wheat cycle.

Figure 3 — Procurement as a Share of Production, Average 2012–2024

0%50%100%37%87%74%30%70%63%PaddyWheatIndiaPunjabHaryanaNational averages include Punjab and Haryana; excluding them, the gap would be wider

Assured procurement of more than four-fifths of Punjab’s paddy makes switching to other crops economically unattractive. Data as cited in the article.

Solutions and Their Limits

• In-situ — crop residue management (CRM) machines (Happy Seeder, Super Seeder, rotavators), short-duration varieties such as PR-126, direct seeding of rice (DSR), and IARI’s PUSA bio-decomposer. But seeders need a costly 60-HP tractor; hiring costs around ₹10,000.
• Ex-situ — using straw for compressed biogas, bio-ethanol, biomass power and co-firing; collection costs ₹1,500–2,500 per acre.
• Haryana’s incentive model — ₹1,000/acre for CRM use, ₹4,000/acre for DSR, ₹7,000/acre for crop diversification, plus panchayat incentives; Punjab has relied mainly on in-situ machinery.
• Enforcement — CPCB flying squads were deployed in 2025; a Parliamentary committee recommended that penalising farmers be the last resort, with a minimum price for selling straw.

▤ The Measurement Problem

• Official claim — Punjab and Haryana together recorded a 90% reduction in fire incidents in 2025 compared with 2022.
• Method — the CREAMS protocol (IARI) counts active fires from NASA’s polar-orbiting MODIS and VIIRS sensors, which pass over India only around 10:30 am–1:30 pm.
• Evidence of evasion — an ISRO-led study using geostationary satellites found farmers shifting burning to evening hours; a multi-satellite estimate of burnt area showed a decline of only about 30%.
• Implication — combine polar and geostationary data and measure burnt area, not just fire counts.

◈ Institutions & Law to Know

• Commission for Air Quality Management in NCR and Adjoining Areas Act, 2021 — created the CAQM (replacing the EPCA); farmers are kept out of its penal provisions but liable to environmental compensation for stubble burning.
• Graded Response Action Plan (GRAP) — staged anti-pollution measures in Delhi-NCR linked to AQI levels.
• Crop Residue Management scheme (2018) — central subsidy for CRM machinery in Punjab, Haryana, UP and Delhi.
• Judicial signals — the NGT (2018) held that farmers who burn stubble could be excluded from MSP benefits, a view the Supreme Court upheld in 2023.

Way Forward

• Short term — affordable access to CRM machines through custom hiring centres, assured straw purchase for CBG plants, promotion of short-duration varieties.
• Medium to long term — diversification away from paddy through price and procurement support for pulses, maize and oilseeds, and rational power pricing.
• Honest measurement — penal targets can create perverse incentives for farmers and officials to show rather than achieve reductions.

✎ Mains Practice Question

“Stubble burning is less a farmer’s choice than the outcome of policy incentives.” Critically examine this statement and suggest a mix of technological, economic and institutional measures to end the practice. 15 marks · 250 words

Living Planet Report 2026: Monitored Wildlife Populations Down 73% Since 1970, but Recovery Is Possible

Core TopicGS-III · Environment — Biodiversity Conservation, Reports & IndicesPrelims + MainsWWF · The Indian Express

WWF’s biennial Living Planet Report 2026 finds that the average size of monitored vertebrate populations fell by 73% between 1970 and 2022. Freshwater species fared worst, and the food system is named the single largest driver of biodiversity loss — yet about half of the tracked populations are stable or increasing.

◈ Basics First — Reading the Living Planet Index Correctly

• Living Planet Index (LPI) — tracks the average rate of change in the relative abundance of monitored vertebrate populations (amphibians, birds, fish, mammals, reptiles).
• What 73% does not mean — it is not the loss of 73% of individual animals, nor of 73% of populations or species; it is the average decline in population size.
• Data base (2026) — 35,803 populations of 5,790 species.
• History — developed by WWF in 1998; managed with the Zoological Society of London (ZSL) since 2006; used as an indicator under the CBD and the Kunming–Montreal Global Biodiversity Framework.
• WWF — founded in 1961; headquartered at Gland, Switzerland (also home to the IUCN).

Figure 4 — Average Decline in Monitored Wildlife Populations, 1970–2022

Global average−73%BY ECOSYSTEMFreshwater−85%Terrestrial−69%Marine−59%BY REGIONLatin America & Caribbean−95%Africa−80%Asia & the Pacific−49%

Freshwater ecosystems — hit by dams, pollution, over-abstraction and invasive species — show the steepest decline. Data: WWF Living Planet Report 2026.

Drivers and Signs of Recovery

• Main drivers — habitat loss and degradation, overexploitation, climate change, invasive species, pollution and disease.
• Food system — the leading cause of habitat destruction and overharvesting, and a major source of greenhouse gas emissions.
• Recoveries — green turtles, bluefin tuna, southern African elephants and tigers: global wild tiger numbers rose from about 3,200 (2010) to around 5,700 (2025).
• India’s share — India holds about three-quarters of the world’s wild tigers; the 2022 estimate was 3,682, reflecting Project Tiger (1973) and the NTCA.
• Positive tipping points — rapid growth of solar, wind and EVs shows systems can change fast; similar shifts are needed in food and finance.

◈ Static Background — The Convention on Biological Diversity

• CBD — opened for signature at the Rio Earth Summit (1992), alongside the UNFCCC; in force from 1993; India became a Party in 1994. Three objectives: conservation, sustainable use, and fair and equitable sharing of benefits.
• Cartagena Protocol on Biosafety — adopted 2000, in force 2003; regulates transboundary movement of living modified organisms.
• Nagoya Protocol on Access and Benefit-Sharing — adopted 2010, in force 2014.
• India’s law — the Biological Diversity Act, 2002 (amended 2023) and the National Biodiversity Authority; the CBD COP meets every two years.
• Kunming–Montreal GBF (2022) — 23 targets for 2030, including protecting 30% of land and sea (“30×30”).

SAREX-2026: Coast Guard Rehearses a Mass Maritime Rescue off Paradip, with Observers from 30 Countries

ImportantGS-III · Security — Maritime Security; Disaster Management · GS-II Regional GroupingsPrelims + MainsPIB · Ministry of Defence

The Indian Coast Guard (ICG) conducted the 12th National Maritime Search & Rescue Exercise (SAREX-2026) off Paradip, Odisha on 7–8 October 2026, simulating a mass rescue operation, and hosted the 24th National Maritime SAR (NMSAR) Board meeting at Bhubaneswar. 32 observers from 30 countries attended.

◈ Basics First — What Is Search and Rescue (SAR)?

• Search and rescue — locating people in distress and delivering them to a place of safety; at sea it covers ship sinkings, fires, man-overboard cases and aircraft ditchings.
• Search and Rescue Region (SRR) — the ocean area for which a country accepts SAR responsibility. India’s maritime SRR covers about 4.6 million sq km of the Indian Ocean.
• Mass Rescue Operation (MRO) — an incident where the number of people in distress exceeds the immediately available rescue capacity, demanding coordination of many agencies.
• Aeronautical–maritime link — air crashes at sea are handled jointly; procedures are harmonised in the IAMSAR Manual, issued jointly by the IMO and ICAO.

▤ Exercise at a Glance

• Scenario: a passenger aircraft with 228 people ditching at sea and colliding with a container vessel — concurrent aeronautical and maritime distress.
• Assets: 15 ICG ships, two Dornier aircraft, three Advanced Light Helicopters and a Chetak, IAF C-130J and Mi-17, two Navy ships, plus civil and State assets.
• International: 32 observers from 30 countries.
• NMSAR Board agenda: SAR preparedness, distress-alert management, faster mobilisation through technology integration and inter-agency coordination.

Static Background — India’s Maritime SAR Architecture

• Indian Coast Guard — set up on an interim basis in February 1977 and given statutory form by the Coast Guard Act, 1978; an armed force of the Union under the Ministry of Defence.
• Coordinating authority — the ICG coordinates maritime SAR in the Indian SRR through Maritime Rescue Coordination Centres (MRCCs) at Mumbai, Chennai and Port Blair.
• NMSAR Board — the apex national body for maritime SAR policy, chaired by the Director General, ICG, bringing together ministries, the armed forces, ports and shipping agencies.
• Distress alerting — the satellite-based COSPAS-SARSAT system (India’s mission control centre is at ISTRAC, Bengaluru) and ISRO-developed distress alert transmitters for fishing boats.
• Legal obligations — SOLAS Convention (1974) and the International Convention on Maritime Search and Rescue (1979) under the IMO; aeronautical SAR under Annex 12 of the Chicago Convention (ICAO).

Significance

• Preparedness — rising sea and air traffic, and the cyclone-prone east coast, make large-scale rescue capability essential.
• Maritime diplomacy — foreign observers support India’s role as a first responder in the Indian Ocean, in line with SAGAR (2015) and MAHASAGAR (2025).
• Interoperability — joint drills among the ICG, Navy, IAF, ports, airlines and State agencies test command, communication and handover procedures.
• Challenges — the vast SRR, safety of small fishing craft, and integration of alerts from multiple systems into a single picture.

✎ Mains Practice Question

India is responsible for search and rescue across a vast area of the Indian Ocean. Discuss the institutional framework for maritime SAR in India and examine how it supports India’s aspiration to be a first responder in the region. 10 marks · 150 words

Nobel Prize in Literature 2026: Canadian Poet-Classicist Anne Carson Honoured for Remaking Literary Forms

ImportantGS-I · Art & Culture — Literature; Awards & Personalities in NewsPrelims + MainsThe Indian Express

Anne Carson (76, Canada) — poet, classicist, essayist and translator — received the 2026 Nobel Prize in Literature “for her bold and inventive oeuvre that, in playful dialogue with the classical tradition, has created new forms for contemporary literature”.

◈ Basics First — The Nobel Prizes

• Origin — established by the will (1895) of Swedish chemist Alfred Nobel, inventor of dynamite; first awarded in 1901 in Physics, Chemistry, Medicine, Literature and Peace.
• Economics — the Sveriges Riksbank Prize in Economic Sciences, added in 1968, is not one of the original five.
• Awarding bodies — Literature: the Swedish Academy (est. 1786); Physics and Chemistry: Royal Swedish Academy of Sciences; Medicine: Nobel Assembly at the Karolinska Institutet; Peace: the Norwegian Nobel Committee in Oslo.
• Recent Literature laureates — Han Kang (South Korea, 2024) and László Krasznahorkai (Hungary, 2025).

Figure 5 — The Laureate and Her Notable Works

Image courtesy The Indian Express, October 2026; reproduced with credit for educational use.

The Laureate and Her Work

• Background — born in Toronto (1950); studied Classics at the University of Toronto; her doctoral thesis (1981) was on the ancient Greek poet Sappho.
• Eros the Bittersweet (1986) — her first book, on desire as created by distance and longing, read through classical texts.
• Autobiography of Red (1998) — a novel in verse recasting the Greek myth of Geryon, the red-winged monster killed by Herakles, as a modern coming-of-age story.
• The Beauty of the Husband (2001) — made her the first woman to win the T.S. Eliot Prize.
• Nox (2010) — an accordion-fold book of grief combining photographs, letters and translation; later works include Float (2016) and Wrong Norma (2024).
• Translations — Sappho (If Not, Winter), Euripides and other Greek classics.

Why She Stands Out

• Genre-blending — a poem becomes an essay, an essay a translation, a translation an autobiography; she rejects fixed literary categories.
• Classics as contemporary — uses ancient Greek myth and fragments to explore modern themes of desire, loss and grief.
• Restraint — writes about intense emotion with deliberate detachment rather than confessional warmth.

▤ India Connect — Prelims Pegs

• Rabindranath Tagore (1913) — the first non-European Literature laureate, for Gitanjali.
• Alice Munro (2013) — the previous Canadian Literature laureate.
• International Booker Prize 2025 — Banu Mushtaq’s Heart Lamp, translated by Deepa Bhasthi, the first Kannada work to win.
