Context: Delhi may witness its first artificial rain through cloud seeding trials in October–November 2025 to tackle pollution and smog.

• The method involves adding silver iodide to clouds to induce rain, aimed at reducing smog during winter.
• Aircraft will remain on standby, and operations will follow Visual Flight Rules (VFR) with necessary ATC and DGCA approvals.
• Trials depend on favourable weather conditions and will be executed with inter-agency coordination.
• Seen as part of Delhi’s 24×7 year-round clean air strategy, the move intends to provide relief from pollution peaks in winter.

Learning Corner:

Cloud Seeding

Definition:
Cloud seeding is a weather modification technique that aims to enhance rainfall or snowfall by dispersing substances into clouds to encourage precipitation.

Process & Method:

• Uses silver iodide, potassium iodide, or dry ice particles, sometimes even salts.
• These act as condensation nuclei, around which moisture condenses to form raindrops or snowflakes.
• Dispersal is done using aircraft, rockets, or ground-based generators.

Types:

1. Static cloud seeding – particles provide nuclei for moisture condensation.
2. Dynamic cloud seeding – enhances vertical air currents, boosting cloud growth.
3. Hygroscopic seeding – uses salts to encourage droplet coalescence in warm clouds.

Applications:

• Increase rainfall in drought-prone regions.
• Mitigate air pollution and smog (e.g., Delhi trials).
• Reduce hailstorm damage.
• Enhance snowfall in ski resorts.

Introduction (Context) 

In September 2025, Ladakh witnessed unprecedented violence as protests for statehood and Sixth Schedule inclusion turned confrontational, leaving four dead and 30 injured. 

• While the Union Territory status granted in 2019 was initially celebrated, repeated agitations since then reflect deep concerns over loss of autonomy, ecological vulnerability, and political marginalization.

Background

• 2019 Reorganisation: Article 370’s repeal and the J&K Reorganisation Act bifurcated the state into UT of J&K (with legislature) and UT of Ladakh (without one).
• Initial optimism vs reality: Ladakhis welcomed separation from J&K but soon realized the weakening of Autonomous Hill Development Councils (LAHDCs), dependence on bureaucracy, and shrinking job opportunities.
• Post-2019 grievances: Lack of a legislature meant local voices were absent in law-making. Growing fears emerged of unchecked mining, industrial encroachment, and cultural dilution.

Trend of Escalating Protests

• March 2024: Sonam Wangchuk’s 21-day hunger strike after failed talks with the Centre.
• Pashmina March 2024: Planned march to highlight grazing land loss and Chinese incursions, stopped under Section 144.
• Delhi Chalo Padyatra 2024: Leh Apex Body (LAB) and Kargil Democratic Alliance (KDA) sought statehood, Sixth Schedule inclusion, local PSC, and separate Lok Sabha seats.
• September 2025: Protests turned violent — a BJP office set ablaze, security forces used tear gas, and clashes left casualties. Wangchuk ended his 15-day fast urging youth to maintain peaceful resistance.

Key Demands 

• Statehood: Full legislative powers for Ladakh to ensure self-governance instead of bureaucratic central control.
• Sixth Schedule inclusion: With over 90% of population tribal, constitutional safeguards are sought for land, resources, and cultural identity.
• Political representation: Demand for two Lok Sabha seats (Leh & Kargil) and Rajya Sabha representation.
• Employment & PSC: A local Public Service Commission and recruitment quotas for Ladakhis to tackle rising joblessness.

Analytical Insights

• Federalism tension: Centralized UT governance without legislature erodes cooperative federalism and participatory democracy.
• Tribal rights: Sixth Schedule inclusion would institutionalize protection of land, resources, and identity, unlike ad-hoc regulations.
• Strategic sensitivity: Security-driven governance must be balanced with local trust, especially in a borderland exposed to Chinese aggression.
• Democratic deficit: With only one Lok Sabha seat and no legislature, Ladakhis feel structurally excluded from India’s democratic framework.
• Electoral promises vs delivery: Protesters highlight that Sixth Schedule inclusion was part of 2019 electoral assurances, yet remains unfulfilled.

Way Forward

• Structured negotiations: Centre must engage LAB and KDA with time-bound commitments.
• Balanced development: Promote jobs and infrastructure while safeguarding fragile ecology.
• Political empowerment: Explore statehood or hybrid models — strengthening LAHDCs until final status.
• Representation: Consider enhanced parliamentary representation and local PSC.
• Trust-building: Address perception of neglect; ensure Ladakhis are partners, not passive recipients, in governance.

Conclusion

The Ladakh protests are not just a local agitation but a test of India’s democratic federalism in a strategically vital region. Meeting demands for statehood and Sixth Schedule protections is essential not only to preserve Ladakh’s unique cultural-ecological identity but also to strengthen national security through inclusive governance.

Mains Practice Question

1. Examine the reasons behind the recurring protests in Ladakh and discuss how the demands for statehood and Sixth Schedule status reflect larger issues of federalism and tribal rights in India. (250 words, 15 marks)

Introduction

Northern States are seeing heavy flooding even in September, with all of Punjab’s 23 districts being hit by floods. Delhi and Gurugram have been inundated by intense rains, and Uttarakhand and Himachal Pradesh are experiencing frequent cloudbursts. In the east, Kolkata is facing torrential rains. 

Key trends

• Heavy rains now occur earlier and later than traditional monsoon months. 
• In May, Mumbai recorded 135.4 mm of rainfall in just 24 hours, followed by 161.9 mm the next day. Delhi recorded 81 mm fall within a few hours on the same day, overwhelming the drainage systems.
• According to the Council on Energy, Environment and Water 64% of Indian tehsils have witnessed a rise in heavy rainfall days (by 1–15 days), especially in Maharashtra, Tamil Nadu, Gujarat, and Karnataka.
• CEEW’s analysis of daily rainfall from 1970 to 2021 in the coastal city of Thane shows that one-hour rainfall now reaches 50 mm once every two years, and about 80 mm per hour once every 50 years. 
• Floods cause the highest loss of life and property among natural disasters, with a single flood causing damages of around ₹8,700 crore.

Gaps in urban flood management

• Calendar-Driven Planning: Urban flood management still relies on fixed monsoon schedules, with drain cleaning and desilting planned for June, even though rain now arrives earlier, later, and with higher intensity. This gap leaves cities unprepared for unseasonal downpours.
• Intense, Short-Duration Rain: Rainfall is increasingly compressed into a few hours, overwhelming drainage systems built for slower, steady rain and causing rapid flooding.
• Outdated Preparedness: Pre-monsoon cleaning and emergency drills follow old timelines instead of real-time rainfall data, while hourly trends are rarely factored into infrastructure design.
• Slow Climate Adaptation: Cities have been slow to update rainfall-intensity data and drainage standards, keeping storm water systems under-designed for today’s extreme weather.

Steps Needed

• Integrate sub-daily rainfall analysis into monsoon planning to account for short, high-intensity rain events and guide both drainage design and real-time operations.
• Use real-time rainfall data to inform citizens and strengthen infrastructure, as seen in Mumbai where drains were widened to handle up to 120 mm rain per hour.
• Acknowledge that seasonal rainfall is increasingly compressed into intense bursts, and design systems to withstand hourly extremes rather than relying only on seasonal averages.
• Align storm water drain cleaning with solid waste management, ensuring schedules are coordinated so that garbage does not reclog freshly cleared drains.
• Activate joint sanitation drives and inspections based on IMD alerts, taking cues from Vijayawada’s monsoon response teams that integrate multiple departments.
• Regularly update Intensity–Duration–Frequency (IDF) curves every 5–10 years so drainage systems reflect evolving rainfall patterns and volumes.
• Design drainage networks using micro-catchment hydrology and topography, and ensure storm water systems are kept separate from sewerage to avoid overload and improve efficiency.

Conclusion
Urban floods are not caused by rain alone but by outdated planning. Cities must shift from seasonal calendars to rainfall-pattern readiness, ensuring infrastructure and operations are agile enough to handle the rain that is already falling.

Mains Practice Question

Q Urban floods in India highlight not just climate variability but systemic gaps in planning, governance, and infrastructure management. Discuss with examples.  (250 words, 15 marks)
