Assam & Disaster Management — Monsoon Flood Crisis

Assam remained under a severe monsoon flood emergency on 23 July 2026. According to the Assam State Disaster Management Authority (ASDMA), as reported by The Hindu and other reliable outlets, 41 people had lost their lives in the current wave of floods since June, with a sharp spike of casualties concentrated in eastern Assam. About 100 people remained missing in the worst-hit belt, Chief Minister Himanta Biswa Sarma said after touring Sivasagar, Charaideo and Jorhat on 22 July to review rescue and relief.

ASDMA-linked situation reports cited for 23 July put roughly 6.53 lakh people as flood-affected across 11 districts, with Sivasagar the worst-hit (about 3.92 lakh), followed by Charaideo (about 1.10 lakh) and Jorhat (about 97,000). ASDMA warned that water levels of the Desang and Dikhow in Sivasagar and the Dhansiri in Golaghat were rising. Revenue and Disaster Management Minister Keshab Mahanta cautioned residents against “flood curiosity” near overflowing channels. For APSC and ADRE: ASDMA as nodal disaster body, the Sivasagar–Charaideo–Jorhat epicentre, Desang–Dikhow–Dhansiri rivers, and long-term Brahmaputra flood–erosion management.

International Affairs & Health — BRICS Health Declaration

On 23 July 2026, the 16th BRICS Health Ministers’ Meeting concluded successfully in Chandigarh under India’s BRICS Chairship 2026. Union Health Minister Jagat Prakash Nadda addressed the meeting; member countries unanimously adopted the 16th BRICS Health Ministerial Declaration. India’s Chairship theme remains “Building for Resilience, Innovation, Cooperation and Sustainability.”

Energy & Nuclear — Nuclear Energy Mission

In a 23 July 2026 Rajya Sabha reply, the Department of Atomic Energy restated progress under the Nuclear Energy Mission (NEM) announced in the Union Budget 2025–26. The Mission targets 100 GWe of nuclear power capacity by 2047 (Viksit Bharat and net-zero 2070 pathway) and development/operationalisation of at least five indigenous Small Modular Reactors (SMRs) by 2033. Present nuclear capacity stands at 8.78 GW, expected to reach about 22 GW by 2031–32 on projects under implementation; NPCIL is envisaged to add about 32 GW beyond 2032 (indigenous PHWRs and LWRs) to about 54 GW, with the balance 46 GW from other PSEs, States, private sector and joint ventures.

BARC is designing three SMR concepts: Bharat Small Modular Reactor (BSMR-200) of 220 MWe (indigenous PWR); SMR-55 of 55 MWe (PWR); and a High Temperature Gas Cooled Reactor (HTGCR) up to 5 MWth for thermochemical hydrogen production (copper–chlorine cycle). The Atomic Energy Commission has approved Tarapur, Maharashtra, as the site for BSMR-200 and SMR-55; HTGCR siting consent is for BARC, Vizag. Parliament enacted the SHANTI Act, 2025, to open nuclear energy to private participation and give the Atomic Energy Regulatory Board (AERB) statutory status for independent regulation. Prelims focus: 100 GW / 2047, five SMRs by 2033, capacity ladder 8.78→22→54→100 GW, SMR types/sites, and SHANTI Act–AERB statutory framing.

Earth Sciences — Mission Mausam

On 23 July 2026, the Ministry of Earth Sciences briefed Parliament on Mission Mausam, launched by the Prime Minister on 14 January 2025 to make India a “Weather-ready and Climate-smart” nation. The Mission strengthens Earth-system observations, modelling and forecasting for seamless weather and climate services, including next-generation radars, wind profilers, satellites, high-performance computing, AI/ML methods and a state-of-the-art Decision Support System (DSS).

IMD currently receives data from 50 Doppler Weather Radars (DWRs); expansion plans include 29 C-Band, 45 X-Band and 12 S-Band DWRs, plus 19 Wind Profiler Systems, 25 Microwave Radiometers and 60 new GPS Radiosonde stations. Global models (GFS of IMD and Mithuna of NCMRWF, Noida) run at 12 km resolution; the Bharat Forecasting System (BharatFS) operates at 6 km for block- and panchayat-level services, supported by enhanced computing (Arunika and Arka). IMD reports about 40% improvement in forecast accuracy for severe weather versus the previous decade. Citizen tools include Mausamgram (Har Har Mausam, Har Ghar Mausam) for hyperlocal forecasts (hourly to 36 hours; three-hourly to five days; six-hourly to ten days by PIN/location/panchayat), the Panchayat Mausam Seva Portal with the Ministry of Panchayati Raj, and apps MAUSAM, MEGHDOOT (agro-met), DAMINI (lightning; IITM) and UMANG. CAP alerts feed SACHET (NDMA) and major platforms. Agro tools KALP and Mausam SANKALP support location- and crop-specific advisories. Exam hooks: launch date, Weather-ready/Climate-smart goal, BharatFS 6 km, Mausamgram, and the 40% accuracy improvement.

Railways & Logistics — Gati Shakti Cargo Terminals

On 23 July 2026, the Ministry of Railways informed the Lok Sabha that 142 Gati Shakti Cargo Terminals (GCTs) have been commissioned under the Gati Shakti Multi-Modal Cargo Terminal policy, which encourages private investment in rail-linked cargo terminals near demand centres. The 142 terminals offer about 224 MTPA freight-handling capacity and have mobilised roughly ₹10,000 crore of private investment; freight handled at GCTs in 2025–26 was 146 MT. In-Principle Approvals (IPAs) cover 310 additional locations.

GCTs handle cement, steel, foodgrains, fertilisers, coal, fly ash, minerals, containers, automobiles and agricultural produce, supporting modal shift from road to rail and lower first- and last-mile costs. Warehousing, silos and cold storage can be developed at terminal sites. State snapshots include Odisha (12) commissioned GCTs, Rajasthan (10), Andhra Pradesh and Bihar (5 each) and Karnataka (4). Railway and economy papers test the policy name, operational count, capacity, private investment and IPA pipeline.

Environment — National Clean Air Programme

In a 23 July 2026 Rajya Sabha reply, the Ministry of Environment, Forest and Climate Change restated outcomes under the National Clean Air Programme (NCAP), launched in 2019 for 130 cities in mission mode with city-, State- and national-level clean-air action plans. Performance-based incentive grants of ₹16,423.56 crore were released to targeted cities from FY 2019–20 to 2025–26. Delhi–NCR air quality coordination continues under the Commission for Air Quality Management (CAQM) created by the CAQM Act, 2021.

Compared with 2017–18, in 2025–26 108 of 130 cities recorded reductions in annual PM10, including 72 cities with more than 20% reduction and 26 with more than 40%. Fourteen cities met National Ambient Air Quality Standards for PM10 (≤ 60 µg/m³), up from six in 2017–18. For PM2.5, 65 of 130 cities met the NAAQS standard of ≤ 40 µg/m³ in 2025–26. Illustrative 2025–26 PM2.5 levels (µg/m³): Pune 41, Hyderabad 34, Surat 32, Delhi 102, Mumbai 33. NAAQS covers 12 pollutants including PM10 and PM2.5; the Air Quality Index (AQI) was launched in 2015. Environment prelims favour launch year, city count, grant figure, CAQM statute year, and the 65-city PM2.5 compliance headline.

Energy Security — E20 Ethanol Blending

On 23 July 2026, the Ministry of Petroleum & Natural Gas reaffirmed the scientific basis and national benefits of E20 (20% ethanol-blended petrol) under the Ethanol Blended Petrol (EBP) Programme. EBP began with a pilot in 2001, E5 in 2006, and progressive higher blends after capacity and regulatory readiness; validation involved NITI Aayog, OMCs, ARAI, SIAM, IIP and manufacturers. Laboratory and field studies support safety and material compatibility for prescribed use, including many legacy vehicles; any mileage impact in some E10-designed vehicles is generally limited to about 3–5%, while E20 offers higher octane and cleaner combustion.

National benefits attributed to the programme: foreign-exchange savings of over ₹1.97 lakh crore, substitution of nearly 316 lakh metric tonnes of crude oil, reduction of about 952 lakh metric tonnes of CO₂ emissions, and transfer of over ₹1.66 lakh crore to farmers. About 8 crore vehicle visits to retail outlets occur daily (roughly 80% petrol). Banking, economy and environment papers routinely test E20 meaning, forex/crude/CO₂/farmer benefit figures, and the consultative rollout architecture.

Science & Technology — Aditya-L1 Achievements

In a 23 July 2026 Rajya Sabha reply, the Department of Space summarised major scientific results from Aditya-L1, India’s dedicated solar physics observatory at the Sun–Earth L1 point for continuous solar viewing. Achievements include the first-ever spectroscopic signatures of the onset phase of a Coronal Mass Ejection (CME); combined insights on intense geomagnetic storms of May and October 2024; the first comprehensive analysis of photospheric iron fluorescence across 47 X-class flares at the peak of Solar Cycle 25 (2024); and high-resolution near-ultraviolet (NUV) observations of powerful flares and a rare solar plasma ejection. Aditya-L1 is classified as a solar physics mission, not a dedicated space-weather satellite, but its data strengthen Sun–Earth connection science and India’s path toward space-weather prediction capability.

The same reply reaffirmed landmark Chandrayaan-3 south-polar science: ChaSTE thermal probe profiles to 10 cm (two-layer “cake-like” regolith; thermal blanket effect in the top few centimetres); APXS on Pragyan supporting the Lunar Magma Ocean hypothesis with magnesium-rich, primitive mantle material; RAMBHA-LP plasma measurements; and ILSA seismometer records at Shiv Shakti point. Experience from Aditya-L1 and Chandrayaan-3 feeds planning for the Venus Orbiter Mission, Chandrayaan-4 and Chandrayaan-5/LuPEX. S&T prelims: L1 placement, CME onset spectroscopy, Solar Cycle 25 / X-class flare work, and the solar-physics versus space-weather distinction.
