1. New Defence Rulebook: Government Notifies Inter-Services Organisations Rules, 2025

Context: In a significant move to modernise India’s defence structure, the Ministry of Defence has officially notified the Inter-Services Organisations (Command, Control & Discipline) Rules, 2025. These rules have been brought into force under the Inter-Services Organisations (ISO) Act, 2023, and will become operational from May 27, 2025.

Why This Matters: Strengthening Joint Military Command

India has long pursued the goal of greater jointness and integration among its armed forces. These new rules are a crucial step in that direction, aiming to streamline the command and disciplinary framework in Joint Services Commands (JSCs) and Inter-Service Organisations (ISOs).

Purpose and Objectives of the New Rules:

• Unified Command Structure: Ensures seamless command and control within joint establishments comprising personnel from the Army, Navy, and Air Force.
• Expedited Disciplinary Procedures: Enables faster resolution of cases by avoiding procedural overlaps between different services.
• Operational Synergy: Facilitates interoperability and administrative efficiency, crucial for joint military operations and national security preparedness.

ISO Act, 2023: Foundation for Integrated Defence Governance

The Inter-Services Organisations Act, 2023 serves as the legislative backbone for the new rules.

• Creation of ISOs: Empowers the Central Government to establish joint structures like theatre commands or integrated service units.
• Central Oversight: The superintendence of all ISOs remains with the government, allowing for national security-centric directives.
• Commanding Officer (CO) Framework: Designates a CO to lead units, ships, or establishments under the ISO umbrella.

Key Features of the ISO Rules, 2025:

• Full Authority to ISO Commanders: The Commander-in-Chief (CiC) of a JSC, the Officer-in-Command (OiC) of Inter-Service Establishments, and the Commanding Officer (CO) of ISO units will now exercise complete disciplinary and administrative control over all attached personnel, regardless of their parent service.
• Preservation of Individual Service Identity: While commanders gain power, the Army Act, Navy Act, and Air Force Act will continue to apply to personnel, ensuring that their core service traditions and legal frameworks remain intact.
• Central Government’s Role in Disputes: In cases not covered by the ISO Rules or Act, final authority rests with the Central Government, ensuring a unified resolution mechanism.
• Continuity in Command: Provisions exist for replacement or interim leadership if the CiC, OiC, or CO is unavailable, preventing any vacuum in command.

Challenges to Implementation:

Despite its progressive framework, the ISO structure may encounter several hurdles:

• Cultural Integration Issues: Each service has a unique identity, operational doctrine, and command culture. Harmonising these differences may lead to internal friction.
• Overlapping Jurisdictions: Dual authority between ISO commanders and parent service chains could result in confusion or command conflicts, especially in sensitive matters like court-martials or administrative actions.
• Legal Complexity: Harmonising provisions across multiple service acts will require careful legal interpretation to avoid contradictions and ensure uniform justice.

Significance for India’s Defence Future:

This development aligns with India’s long-term plan to implement Integrated Theatre Commands, a reform envisioned by the Chief of Defence Staff (CDS) to enhance tri-service synergy. Countries like the United States, Russia, and China already operate under joint command structures for strategic and operational advantage.

Conclusion: A Step Closer to a Unified War-Fighting Machine

The notification of the Inter-Services Organisations (Command, Control & Discipline) Rules, 2025 signals a new era in India’s defence administration. While implementation will require patience and coordination, the long-term benefits in terms of efficiency, accountability, and combat readiness are undeniable.

2. Global Temperature Likely to Breach 1.5°C in Next Five Years: WMO

Context: The World Meteorological Organization (WMO) has released its latest climate outlook titled ‘Global Annual to Decadal Climate Update (2025–2029)’, offering a sobering forecast for global temperatures. The findings point towards an increasing likelihood of breaching the critical 1.5°C warming limit, as set by the Paris Agreement.

Key Findings: Temperature Projections for 2025–2029

• 2024: Already marked as the hottest year ever recorded, it was the first year to temporarily exceed the 1.5°C mark above pre-industrial levels (1850–1900 baseline).
• 2025–2029 Outlook:
  • There is a 70% probability that the average global temperature for this period will surpass 1.5°C above the pre-industrial baseline.
  • There is an 80% chance that at least one year will exceed the record set in 2024.
  • An 86% likelihood that at least one year in this five-year period will breach the 1.5°C threshold.
  • The projected temperature range lies between 1.2°C and 1.9°C above the 1850–1900 average.
  • A 1% probability exists for exceeding 2°C in any one of the next five years—an early sign of potentially irreversible climate damage.

Regional Climate Outlook: What to Expect Globally and Locally

• South Asia: Continued trend of wetter-than-usual monsoon seasons is likely (barring occasional dry years like 2023). The India Meteorological Department (IMD) has forecast above-normal monsoon rainfall in 2025.
• Arctic Region:
  • Projected to warm by approximately 2.4°C during winters (Nov–Mar), which is 3.5 times faster than the global average.
  • Significant decline in sea ice expected in regions like the Barents Sea, Bering Sea, and Sea of Okhotsk.
• Other Regional Projections (2025–2029):
  • Wetter regions: Sahel, Northern Europe, Alaska, and Northern Siberia.
  • Drier regions: Amazon basin—raising alarms about deforestation and ecological balance.

Paris Agreement: Understanding the 1.5°C Limit

• Adopted at COP21 in 2015, the Paris Agreement is a legally binding global treaty aimed at curbing climate change.

• It seeks to limit warming to below 2°C, while striving to cap it at 1.5°C.
• The 1.5°C target is a global ambition, not a legal threshold, and refers to long-term temperature averages over decades, not single-year anomalies.
• Countries commit to Nationally Determined Contributions (NDCs), which must be updated every five years to reflect growing ambition.
  • Alarmingly, 180 of the 195 signatories have yet to submit updated NDCs for the 2031–2035 period, due before COP30.

About the World Meteorological Organization (WMO):

• WMO is a specialized agency of the United Nations, established in 1950, with 193 member countries and territories.
• It is the global authority on weather, climate, operational hydrology, and geophysical sciences.
• Headquartered in Geneva, Switzerland, its highest decision-making body is the World Meteorological Congress.

Why This Matters: The World Is Running Out of Time

This forecast serves as a red alert for humanity. Breaching the 1.5°C limit could trigger irreversible climate tipping points—including melting polar ice, rising sea levels, and disruptions to global food and water supplies.

6. Urban Flooding in India: A Rising Crisis Amidst Rapid Urbanization and Climate Change

Context: Bengaluru recently witnessed intense pre-monsoon showers resulting in severe waterlogging, overflowing lakes, and substantial damage to life and property. With an early monsoon onset this year, the threat of urban flooding is expected to worsen across Indian cities, especially those already struggling with poor drainage and rapid urban expansion.

Understanding Urban Flooding:

Urban flooding refers to the inundation of land or property in densely populated urban areas, primarily caused by heavy rainfall, inadequate drainage systems, river overflows, and encroachment on natural water bodies. Unlike rural flooding, urban floods have higher economic, infrastructural, and human costs due to population density and infrastructure complexity.

Notable Examples:

• Bengaluru (2024): Overflowing lakes and submerged IT hubs.
• Delhi (2023): Yamuna river breached embankments after record rain.
• Mumbai (2020): Monsoon floods halted transport and damaged property.
• Chennai (2015): Cyclonic rains led to massive inundation and power cuts.

Key Causes of Urban Flooding in India:

Natural Factors:

• Heavy Monsoon Rainfall: The Indian subcontinent experiences intense monsoon bursts, especially during June–September. Cities like Mumbai, located along the Western Ghats, are prone to flash floods due to high rainfall in short durations.
  • E.g., Chennai (2015) experienced historic rainfall due to a cyclonic system over the Bay of Bengal.
• Geographical and Topographical Challenges: Many Indian cities are built on floodplains, coastal belts, or low-lying zones, making them naturally vulnerable.
  • Mumbai is on the Konkan coast, and Kolkata lies in the Ganga-Brahmaputra delta.
  • Even cities at higher elevations like Bengaluru (900 m above sea level) lack natural drainage outlets like major rivers.
• Climate Change and Extreme Weather Events: Global warming has led to unpredictable and intense weather patterns, causing frequent cloudbursts and flash floods.
  • Delhi (2023) faced major flooding due to record-breaking rainfall within a short span.

Anthropogenic (Human-Induced) Factors:

• Unplanned Urbanization and Land Encroachment: Rapid urban growth has led to the concretization of natural landscapes, obstructing natural water flow.
  • Bengaluru, which once had over 1,000 lakes, has lost nearly 80% to construction and encroachment.
• Outdated and Inadequate Drainage Systems: Many urban centres still rely on colonial-era drainage infrastructure, which is ill-equipped to handle modern rainfall intensities.
  • Mumbai’s drainage, designed for just 25 mm/hour, is easily overwhelmed.
• Solid Waste Mismanagement: Unregulated dumping of plastic and waste clogs drains and nullahs.
  • In the 2023 Himachal Pradesh floods, blocked waterways worsened damage.
• Deforestation and Soil Erosion: In hill regions, deforestation, shifting cultivation (Jhum), and poor land-use practices cause increased runoff and siltation.
  • Guwahati (Assam) frequently floods due to such upstream land degradation.

Major Impacts of Urban Flooding:

• Severe Economic Losses: Damages to infrastructure, transportation, housing, and businesses run into thousands of crores.
  • Chennai (2015) suffered losses exceeding ₹15,000 crore.
• Public Health Emergencies: Stagnant floodwater fosters mosquito breeding, causing malaria, dengue, and waterborne diseases like cholera, typhoid, and hepatitis.
  • Kerala (2020) saw a spike in leptospirosis cases post-flooding.
• Displacement and Inequality: Floods disproportionately affect the urban poor, especially slum dwellers and those in low-lying, informal settlements.
  • Mumbai (2022) floods rendered thousands homeless and jobless.
• Environmental and Ecological Damage: Floodwaters carry sewage, industrial waste, and plastics, polluting lakes, rivers, and groundwater.
  • Bengaluru’s lakes, like Bellandur, have seen foam and toxic froth after floods.
• Overstressed Infrastructure: Frequent floods expose systemic flaws in urban planning, from underground drainage to surface water retention systems.

How Can India Build Resilience Against Urban Flooding?

1. Integrated Watershed and River Basin Management:

Adopt comprehensive flood control by managing entire catchment areas, from hills to plains.

• The Netherlands’ “Room for the River” project provides a successful model—allocating space for rivers to expand safely.

2. Implement Sustainable Urban Drainage Systems (SUDS):

Use nature-based drainage alternatives such as:

• Permeable pavements
• Rain gardens and bioswales
• Detention and retention ponds :These systems reduce surface runoff and enhance groundwater recharge.

3. Embrace the Sponge City Model:

A “Sponge City” uses green infrastructure to absorb, store, and reuse rainwater, helping mitigate flood peaks.

• Shanghai has implemented green roofs, porous pavements, and urban wetlands.
• Mumbai is currently integrating this model into its stormwater strategy.

4. Revive and Restore Urban Water Bodies:

• Lakes, tanks, and wetlands act as natural flood buffers.
• Bengaluru’s Jakkur Lake restoration is a prime example of how eco-restoration helps flood control.

5. Community Involvement and Early Warning Systems:

• Engage local communities in disaster risk reduction, education, and preparedness drills.
• Use real-time monitoring tools like Singapore’s SWAN (Smart Water Assessment Network), which sends alerts via SMS based on live water level data.

6. Policy and Urban Planning Reforms:

• Strengthen zoning regulations, protect green belts, and enforce building codes to avoid construction in flood-prone zones.
• Include climate-resilient infrastructure in urban master plans.

Extra Insight: India’s Urban Flooding Challenge by the Numbers

• 45 million people in India are directly exposed to urban flood risk annually (UNDRR, 2023).
• 50,000 crore is India’s average annual loss due to flood-related disasters (World Bank Report).
• Over 75% of India’s cities lack basic stormwater management plans.

Conclusion: A Call for Sustainable Urban Transformation

Urban flooding is not just a natural disaster—it’s a man-made crisis rooted in poor planning, ecological neglect, and climate vulnerability. India must move toward climate-responsive urban development that prioritizes resilient infrastructure, restored ecosystems, and community-led adaptation.

The way forward lies in:

• Learning from global best practices
• Investing in green infrastructure
• Coordinating across agencies
• And most importantly, putting nature at the heart of urban planning
