General Studies-3; Topic: Disaster and disaster management.
Introduction
- The 2025 south-west monsoon has once again exposed the vulnerability of Northeast India to rain-related disasters.
- In its early phase, the monsoon has caused widespread devastation across states such as Assam, Arunachal Pradesh, Sikkim, Meghalaya, Mizoram, Tripura, and Manipur.
- Torrential rains, swollen rivers, landslides, collapsing infrastructure, and displaced communities highlight the growing humanitarian and ecological crisis.
Geographical and Environmental Vulnerabilities of the Northeast
- Topography and Drainage
-
- The Northeast is a mountainous and hilly region interspersed with narrow valleys and major rivers like the Brahmaputra and Barak.
- Hills with steep gradients accelerate runoff, which overwhelms low-lying floodplains quickly.
- The Brahmaputra, with over 50 tributaries, is prone to erosion and frequent course shifts, making embankments often ineffective.
- Heavy Rainfall and Monsoon Dependence
-
- The region receives 2000–4000 mm of rainfall annually (IMD).
- Cherrapunji and Mawsynram in Meghalaya are among the world’s wettest places.
- Intense rainfall in a short span increases flash flood and landslide risk, especially in deforested or unplanned urban areas.
Impact of Climate Change on Rainfall and Disasters
- Erratic Rainfall Patterns
-
- According to the State of India’s Climate Report (MoES, 2023), monsoon rainfall variability has increased in the Northeast.
- Shorter spells of extremely heavy rain are becoming common, overwhelming drainage systems.
- Melting Glaciers and Glacial Lake Outburst Floods (GLOFs)
-
- In Sikkim, the melting of Himalayan glaciers due to global warming has increased the risk of GLOFs.
- In October 2023, Sikkim witnessed a flash flood in the Teesta River following a glacial lake burst, killing over 100 people.
- Shifting Flood Zones
-
- Traditionally flood-safe areas are now experiencing inundation.
- For instance, parts of Manipur and upper Arunachal are now reporting annual flood damage for the first time.
Institutional and Infrastructural Gaps
- Failure of Embankments
-
- Embankments often breach due to poor maintenance or pressure from increased river discharge.
- According to CAG reports (2018, Assam), nearly 40% of embankments in Assam were overdue for repair.
- Absence of Integrated River Basin Management
-
- Northeast India lacks a unified Brahmaputra River Basin Authority with flood forecasting, zoning, and disaster mitigation powers.
- Urban Flooding Due to Unplanned Growth
-
- Cities like Guwahati are prone to urban floods due to construction over wetlands and hill slopes.
- Weak Early Warning Systems
-
- Though ISRO and IMD provide satellite-based flood alerts, local-level response mechanisms remain underdeveloped.
Socio-Economic Impact
- Human Displacement
-
- Over 3 lakh people displaced across the Northeast this season.
- Temporary shelters lack basic amenities and security for women and children.
- Infrastructure Loss
-
- Roads, bridges, and schools in Sikkim, Manipur, and Assam damaged.
- Economic loss projected to run into hundreds of crores.
- Agricultural Disruption
-
- Paddy fields in Assam and Tripura submerged.
- Livestock loss and silting of fields reduce productivity, affecting farmer incomes.
Long-Term and Sustainable Solutions
- Integrated Flood Management Plan
-
- A Brahmaputra Flood Management Authority is essential with inter-state coordination.
- River linking, dredging, and controlled diversions during flood peaks must be considered.
- Nature-Based Solutions
-
- Restore wetlands (like Deepor Beel in Assam) that naturally absorb floodwater.
- Afforestation on hill slopes to reduce erosion and landslides.
- Climate Adaptation and Resilient Infrastructure
-
- Use climate-resilient materials and designs for roads, embankments, and buildings in high-risk zones.
- IMD’s district-level forecasting must be integrated with Gram Panchayat-level action plans.
- Community-Based Disaster Risk Reduction (CBDRR)
-
- Local NGOs and SHGs should be trained in emergency response, first aid, and community shelter management.
- Japan’s model of disaster drills and resilient schooling systems can be adapted.
Role of Government and Institutions
Agency | Responsibilities |
NDMA (National Disaster Management Authority) | Formulating disaster-resilient policies |
IMD | Accurate monsoon and flood forecasting |
NDRF | On-ground rescue and rehabilitation |
State Disaster Response Forces | First responders in remote hilly regions |
Ministry of Jal Shakti | River basin planning and embankment maintenance |
International Best Practices to Emulate
- Netherlands: Focus on “living with water” — creating floodplains and adaptive architecture.
- Bangladesh: Community-level flood shelters and participatory flood risk maps.
- Japan: Real-time landslide sensors and public alert systems with education drills.
Way Forward
- Declare Flooding as a National Disaster Category for high-impact zones in Northeast.
- Allocate dedicated climate adaptation funds for the region under National Adaptation Fund for Climate Change (NAFCC).
- Enhance coordination between state governments and central agencies.
- Invest in satellite-based real-time monitoring and AI-powered flood risk modeling.
- Revise town planning laws to integrate climate risk zoning and limit hill-cutting, concretization, and wetland reclamation.
Conclusion
- The ongoing devastation in Northeast India from the early phases of the 2025 monsoon reflects a systemic failure of planning, adaptation, and governance.
- The region needs not just relief measures but a paradigm shift towards sustainable and climate-resilient planning.
- Empowering communities, investing in long-term ecological infrastructure, and adopting global best practices are the keys to safeguarding the region’s people and economy in the face of an increasingly volatile climate.
