Syllabus Mapping: GS-III – Indian Economy | Energy Security | Mineral Resources | Coal Sector Reforms | Critical Minerals |
- The 4th Conference of Mining Ministers, organised by the Ministry of Mines on 5–6 November 2026 in Goa, focused on reforms in the coal and mining sectors, with participation from State Mining Ministers and senior Central and State Government officials.
- Union Minister G. Kishan Reddy emphasised accelerating coal gasification, strengthening domestic critical mineral capabilities, adopting AI-driven mining technologies and improving Centre-State coordination to enhance energy security and support Viksit Bharat 2047.
- Coal gasification converts coal into synthesis gas (syngas), primarily comprising carbon monoxide and hydrogen, which can be used to produce chemicals, synthetic fuels, hydrogen and other industrial products. It enables value addition beyond conventional coal combustion and supports industrial diversification.
- Coal gasification can help utilise domestic coal resources, reduce dependence on imported gas and certain chemical intermediates, generate employment and expand downstream industrial applications. However, its adoption requires high capital investment, suitable technology, water availability and effective management of emissions and environmental impacts.
- The Minister highlighted the need to strengthen the entire critical mineral value chain, covering exploration, mining, processing, refining and recycling, to reduce import dependence and improve strategic and economic resilience.
- Critical minerals such as lithium, cobalt, nickel and rare earth elements are important for electric vehicle batteries, renewable energy technologies, electronics, defence and advanced manufacturing. Their supply-chain concentration creates vulnerabilities arising from geopolitical disruptions and export restrictions.
- States were urged to expedite the operationalisation of auctioned mines, accelerate fresh mineral block auctions, expand exploration and facilitate investment in mining infrastructure.
- Secretary, Ministry of Coal, highlighted that domestic coal production had exceeded one billion tonnes for the second consecutive year, reflecting the growing contribution of domestic production to India’s energy security.
- Important coal-sector initiatives include Commercial Coal Mining, the revised SHAKTI framework and Coal SETU. While the revised SHAKTI framework rationalises coal linkages for the power sector, Coal SETU creates a separate window under the Non-Regulated Sector linkage policy to facilitate coal allocation for industrial use, export and other permitted purposes.
- First Mile Connectivity (FMC) aims to improve coal transportation from mines through mechanised loading and handling infrastructure, reducing dependence on conventional road transportation and improving logistics efficiency.
- The conference also emphasised integrating mine rehabilitation and alternative livelihood opportunities into mining operations from the beginning, alongside environmental protection and the welfare of mining-affected communities.
- Post-mining rehabilitation involves restoring mined-out areas through measures such as land reclamation, afforestation, water-body development and productive reuse of abandoned mining land. It supports environmental restoration and sustainable regional development.

Syllabus Mapping: GS-II – International Institutions | Multilateral Cooperation | GS-III – International Trade | Mineral Resources |
- As Chair of the Kimberley Process (KP) for 2026, India convened a stakeholder consultation in Luanda, Angola, on 3 November 2026, ahead of the KP Plenary scheduled in New Delhi from 30 November to 4 December 2026.
- India’s Chairship is guided by the theme Confidence, Compliance and Credibility, focusing on responsible sourcing of rough diamonds, institutional governance, certification, participant compliance and consumer confidence.
- The Kimberley Process Certification Scheme (KPCS) was established pursuant to UN General Assembly Resolution 55/56 (2000) to prevent conflict diamonds from entering the legitimate rough diamond trade.
- Conflict diamonds, also known as blood diamonds, refer to rough diamonds used by rebel movements or their allies to finance armed conflicts aimed at undermining legitimate governments. The Kimberley Process seeks to restrict their entry into international trade through certification requirements.
- The KPCS operates through a tripartite framework involving Governments, the diamond industry and civil society, recognising that effective control of the diamond supply chain requires cooperation among public authorities and non-governmental stakeholders.
- The Kimberley Process has 60 Participants representing 86 countries, with the European Union and its Member States participating as a single entity. Its Chairship rotates annually among participating countries.
- India holds Observer status in the African Diamond Producers’ Association (ADPA), providing an institutional platform for engagement with African diamond-producing countries on rough diamond supply chains, technical cooperation, value addition, market access and sustainable practices.
- Established on 4 November 2006 in Luanda, Angola, ADPA promotes cooperation among African diamond-producing nations. It comprises 15 effective member countries and eight observers, including India and Russia, and its members collectively account for over 60% of global diamond production.
- The 13th Extraordinary Meeting of the ADPA Council of Ministers approved a Memorandum of Understanding between the Gem & Jewellery Export Promotion Council (GJEPC), India, and ADPA to strengthen cooperation in capacity building, diamond sorting, valuation, manufacturing skills, technical knowledge exchange, trade and investment.
3. DRDO – Successful Flight-Test of Quasi-Ballistic Missile ‘Pralay’
Syllabus Mapping: GS-III – Science and Technology | Defence Technology | Indigenisation of Defence Production | Internal Security
- The Defence Research and Development Organisation (DRDO) successfully conducted the flight-test of the indigenously developed Pralay quasi-ballistic missile on 5 November 2026 from Dr APJ Abdul Kalam Island, off the coast of Odisha.
- All test objectives were achieved, as confirmed by data captured through range instruments deployed by the Integrated Test Range (ITR), Chandipur. The test was conducted as part of user evaluation trials in the presence of DRDO, Defence Forces and industry representatives.
- Pralay has been indigenously developed by Research Centre Imarat (RCI), Hyderabad, along with other DRDO laboratories. Bharat Dynamics Limited (BDL), one of its Development-cum-Production Partners, has manufactured the missile system.
- Following the successful flight-test, the system’s induction into the Armed Forces has become imminent, according to the Ministry of Defence.
- A quasi-ballistic missile follows a ballistic trajectory but possesses the ability to manoeuvre during flight, making its trajectory less predictable than that of a conventional ballistic missile.
- Unlike conventional ballistic missiles that largely follow a predictable trajectory after powered flight, manoeuvrability in quasi-ballistic systems can complicate interception and improve their ability to respond to changing operational requirements.
4. Exercise Malabar 2026 – India’s Maritime Cooperation in the Indo-Pacific
Syllabus Mapping: GS-II – India’s Foreign Relations | India–Japan Relations | QUAD | GS-III – Maritime Security |- INS Sahyadri, an indigenous Guided Missile Stealth Frigate of the Indian Navy’s Eastern Fleet, arrived at Yokosuka Naval Base, Japan, on 4 November 2026 to participate in the multilateral naval exercise MALABAR 2026.
- The exercise brings together the navies of India, Japan, the United States and Australia, providing a platform to strengthen maritime interoperability, operational coordination and professional cooperation.
- The exercise comprises a harbour phase, involving professional interactions and coordinated planning, followed by a sea phase involving INS Sahyadri and participating naval units of the three partner countries.
- Exercise Malabar provides an opportunity for participating navies to enhance mutual trust, exchange operational expertise and improve coordination in addressing maritime security challenges.
- The participation of the four countries reflects their growing maritime cooperation and shared interest in maintaining a free, open, inclusive and stable Indo-Pacific.
- The four participating countries are also members of the Quadrilateral Security Dialogue (Quad), an informal strategic grouping focused on cooperation in areas including maritime security, critical technologies, infrastructure and regional stability.
- India’s participation aligns with its MAHASAGAR (Mutual and Holistic Advancement for Security and Growth Across Regions) vision, which emphasises maritime cooperation, security and development across regions.
5. UBC 63 – Discovery of a Double Star Cluster System
Syllabus Mapping: GS-III – Science and Technology | Space Technology | Astronomy | Astrophysics
- A team led by Indian astronomers has discovered that UBC 63, previously identified as a single Galactic open cluster located approximately 4,892 light-years from Earth, actually comprises two distinct stellar clusters, designated UBC 63A and UBC 63B, which underwent a close but unbound gravitational flyby.
- The discovery provides an opportunity to study the aftermath of a close encounter between two stellar systems and understand the role of gravitational interactions in the dynamical evolution of star clusters within the Milky Way.
- The research involved scientists from Gauhati University, Indian Institute of Astrophysics (IIA) and other national and international institutions, using observations from the European Space Agency’s Gaia mission.
- Star clusters are groups of stars formed within the same large reservoirs of gas and dust. They evolve under the influence of their own gravitational interactions and the wider gravitational environment of the Milky Way.
- Analysis of stellar brightness and colours revealed two distinct sequences in the Colour-Magnitude Diagram (CMD), an astronomical tool used to study the evolutionary stages and properties of stars in a cluster.
- Further analysis of stellar motions, machine learning techniques and high-performance-computing-based dynamical simulations confirmed the presence of two separate stellar populations.
- UBC 63A is approximately 21 million years old, whereas UBC 63B is approximately 562 million years old. Their substantial age difference indicates that they did not originate as a single star cluster.
- Dynamical simulations revealed that the two clusters were separated by approximately 60 parsecs (196 light-years) when the younger cluster formed. They approached each other around 6 million years ago, reaching a minimum separation of approximately 7 parsecs (23 light-years).
- The clusters are currently about 26 parsecs (85 light-years) apart and are not gravitationally bound. They are moving away from each other following their close encounter.
- Gaia Mission: Launched by the European Space Agency (ESA), Gaia is an astrometric space observatory that measures the positions, distances and motions of stars with high precision to create a detailed three-dimensional map of the Milky Way.
- Open Star Clusters: These are relatively loosely bound groups of stars that generally originate from the same molecular cloud. Their structures and evolution are influenced by internal gravitational interactions and external forces within the galaxy.
