Editorial 1: Securing valleys and slopes
Context:
The recent devastating floods in Dehradun have once again highlighted the fragility of mountainous states in India. The 2025 monsoon unleashed destruction across Jammu & Kashmir, Himachal Pradesh, Punjab, and Uttarakhand, reminding us of the Himalayas’ vulnerability to extreme weather, unstable geology, and fragile ecosystems. These floods underline the urgency of strengthening disaster preparedness, integrating modern technology, and ensuring coordinated responses.
Challenges of the Himalayan Landscape:
- The Himalayan region is prone to frequent floods, cloudbursts, landslides, and glacial lake outbursts. The terrain, marked by steep valleys and fragile slopes, makes both rescue and relief operations difficult.
- Rapid urbanization, unplanned construction, and road-cutting projects have further destabilized slopes, while climate change intensifies rainfall variability and extreme events.
- Every year, local communities and disaster management forces face repeated cycles of tragedy. Unlike the plains, where water flows out easily, the mountains trap floods in valleys, sweeping away homes, roads, and fields.
- This geographical reality demands a specialized and proactive approach to disaster management.
Present Disaster response regime:
- The present disaster response regime has responded to these disasters with speed, coordination, and innovation.
- Soldiers, engineers, paramilitary forces, disaster response officials, and local government officials have coordinated to save lives.
- In J&K, during floods in Chenab and Tawi rivers, Army laid Bailey bridges within an hour, Air Force deployed its helicopters and the NDRF surged in with the specialist teams.
- During Punjab floods, NDMA coordinated with Central Water Commission, IMD, and BBMB to regulate water releases from Bhakra and Pong dams and prevent catastrophic breaches.
- Drone imageries are used extensively to assess the damage and guide relief efforts.
- In Uttarakhand, Army built a 400-foot aerial cableway; Airforce used its Chinook to lift heavy equipments. SDRF and ITBP, supported by drones and satellite communication links, ensured quick evacuation.
- While the official response was agile, it was still largely reactive rather than preventive.
- The intensity of rainfall was underestimated, and technology was not adequately deployed in advance.
- This point to systemic weaknesses in India’s disaster management approach in the Himalayas.
Use of technology in Disaster Management:
- To manage disasters in the Himalayas effectively, India must move beyond conventional relief measures. A technology scale-up is essential for effective disaster management.
- Geospatial Monitoring: The Geological Survey of India (GSI) must expand slope stability and landslide mapping.
- The National Remote Sensing Centre (NRSC) should use satellites to monitor glacial lakes, river flows, and snowmelt in real time.
- Artificial Intelligence (AI) and Big Data: Predictive models based on rainfall patterns, soil data, and satellite imagery should warn communities days before disasters strike.
- Gorakhpur Model of urban flood control should be used as case study for developing flood control models suitable to the local condition.
- AI-enabled platforms can integrate data from sensors, drones, and satellites for dynamic risk assessment.
- Drones and high-resolution satellites should be used to continuously monitor vulnerable valleys.
- Automated sirens, alarms, and early-warning apps can be used to alert villages of rising water levels.
- Digital mapping of roads, slopes, and catchment areas can identify choke points.
- Flood-resistant housing and slope-protecting embankments must replace haphazard construction.
- Disaster education needs to be integrated into schools and colleges in mountain states.
- Panchayats must hold regular mock drills, ensuring that every village knows evacuation routes and shelter points.
Institutional and Policy Measures:
- Despite the early warning SMS sent to many phone users, many people remain unaware of the disaster response. Machail and Gangotri corridors have seen increased footfall of pilgrims even during red alert.
- Construction in riverbeds, slope destabilization by unchecked developments continues abated in the Himalayas.
- Agencies like the NDMA (National Disaster Management Authority) must strengthen collaboration with local governments.
- NDMA’s Aapda Mitra programme must be extended to cover schools, Panchayats, and resident welfare Associations.
- State governments should organize regular training and awareness events jointly with the NDMA.
- Temporary shelters, equipped with modern sanitation and healthcare, should be pre-identified and stocked before the monsoon.
- Legal frameworks also need updating. Clear accountability mechanisms must ensure that construction projects in sensitive Himalayan zones are strictly monitored.
- Currently, violations of environmental laws and lax regulation contribute to recurring disasters.
- The Ministry of Earth Sciences, Ministry of Home Affairs, and Defense Forces must work together under a common national framework for Himalayan disaster resilience. At present, fragmented approaches weaken overall preparedness.
Building a Future-Ready System:
- The vision must be preventive, not just reactive.
- The Himalayan region cannot afford to live in a cycle of “disaster → rescue → rehabilitation → repeat.” Instead, it must be reimagined through technology, foresight, and community resilience.
- Roads and river embankments must be built with slope stabilization to prevent landslides, mudslides and land leaching.
- The illegal sand mining makes the dams fragile; it must be curbed using suitable legislations, proper patrolling, and community participation.
- The density of Doppler radars must be expanded across valleys, and early warning systems must be made more localized. This also requires developing trained workforce in Disaster management.
- Sustainable building practices, adherence to seismic codes, and strict enforcement of “no-build zones” along riverbanks must be increased.
- All future development projects must be made “Disaster Resilience” in the ecologically-fragile Himalaya.
Way Forward:
The climate change has made Himalayan disasters both frequent and severe. While the government’s disaster response machinery has become quicker, the overall approach remains insufficiently proactive. Only a large-scale infusion of technology, backed by legal enforcement and grassroots awareness, can secure the fragile slopes and valleys of the Himalayas. India must treat the Himalayas as an ecological treasure and a high-risk zone simultaneously. Protecting lives, livelihoods, and ecosystems here will require political will, cutting-edge technology, and continuous vigilance.
