Why in the News?
- Punjab witnessed its worst floods since 1988 in August 2023, caused by overflowing waters from the Sutlej, Beas, and Ravi rivers.
- Around the same time, intense rainfall triggered floods and landslides in Uttarakhand, Jammu & Kashmir, and Pakistan, leading to significant casualties and destruction.
- The Supreme Court expressed deep concern over reckless development in Himalayan states, linking it with increasing climate-related disasters.
Key Highlights
- Recurring Himalayan Disasters
- The Indian Himalayan region has witnessed several catastrophic floods and landslides in the last decade — the Kedarnath disaster in 2013, the Chamoli disaster in 2021, and the recent 2023 floods in Uttarkashi and Punjab. These disasters resulted in thousands of deaths, large-scale displacement, and destruction of infrastructure.
- While often described as “acts of God” or unprecedented cloudbursts, experts point out that many of these disasters were worsened by human activities such as deforestation, haphazard construction, and unscientific road-widening projects.
- The cumulative pattern shows that the Himalayas are becoming increasingly fragile due to the combined impact of natural geological instability and anthropogenic interventions.
- Role of Climate Change and Development
- Climate Change refers to long-term shifts in temperature, precipitation patterns, wind, and other aspects of the Earth’s climate system, primarily caused by natural processes and more recently accelerated by human activities such as greenhouse gas emissions, deforestation, and industrialisation.
- Climate change has intensified rainfall variability, leading to extreme weather events such as cloudbursts and flash floods. Rising temperatures have accelerated glacial melting, contributing to the formation of unstable glacial lakes.
- Development activities like road construction, tunneling for highways, and large-scale hydropower projects are disturbing the natural slope stability of the Himalayas. The removal of vegetation and blasting of rocks further weakens the landscape.
- Experts emphasise that disasters in the region cannot be seen only as “natural phenomena” but as outcomes of the interaction between climate change and unsustainable development practices.
- Judicial Interventions and Warnings
- The Supreme Court has repeatedly expressed concern about the unchecked development in ecologically fragile Himalayan states. In July 2023, it warned that Himachal Pradesh could “vanish from the map” if reckless construction continues.
- Visual evidence, such as tree logs floating in floodwaters, highlighted the scale of deforestation. The Court observed that development should not come at the cost of forests, environment, and human lives.
- The judiciary has stressed that governments must ensure a balance between revenue generation and ecological sustainability, underlining the urgent need for environmental accountability in policymaking.
- Infrastructure and Hydropower Pressure
- Himachal Pradesh alone has over 1,144 hydropower projects at various stages: 180 operational, 53 under construction, and 721 awaiting clearance. Uttarakhand has 40 operational plants and 87 more planned.
- The sheer scale of these projects means constant blasting, tunneling, and diversion of rivers, which destabilises fragile mountain ecosystems and heightens landslide and flood risks.
- Road-widening projects for highways and tourism expansion add further stress. The construction of tunnels, as seen along the Chandigarh-Manali stretch, has even been described as creating “death traps” during heavy rains.
- Together, these activities create a development paradox: while aiming to improve connectivity and power generation, they simultaneously amplify disaster vulnerability.
- Rising Glacial Threats
- The Indian Himalayan region is experiencing temperature rise at a rate faster than the global average. This has led to reduced snowfall, faster snowmelt, and the creation of new glacial lakes.
- By 2018, research identified over 25,000 glacial lakes in five major Himalayan river basins, many of which are unstable. Any breach of the natural barriers holding these lakes can cause Glacial Lake Outburst Floods (GLOFs), releasing massive amounts of water downstream within hours.
- Such events pose grave risks to downstream villages, infrastructure, and livelihoods. Given the increasing tourism and settlement patterns in vulnerable areas, the human cost of these disasters could rise further in the future.
- Experts warn that without urgent monitoring, early warning systems, and sustainable planning, GLOFs could become frequent and devastating.
Implications
- Environmental Degradation
- Large-scale deforestation weakens soil stability.
- Cutting deodar trees increases erosion and flood risks downstream.
- Socio-Economic Consequences
- Villages face destruction of homes, schools, and hospitals.
- Loss of livelihoods due to damaged agriculture, tourism decline, and displacement.
- Governance and Planning Challenges
- Development models borrowed from urban areas are unsuited for fragile Himalayan ecosystems.
- Weak disaster impact assessments and absence of carrying-capacity studies worsen the problem.
- Tourism and Local Pressures
- Rising tourism drives demand for hotels and homestays, leading to unregulated construction.
- Locals face pressure on land, forests, and water resources.
- Strategic and Future Risks
- GLOFs and floods may disrupt national infrastructure, power generation, and connectivity.
- Long-term demographic and migration pressures may increase if disasters worsen.
Challenges and Way Forward
Challenges | Way Forward |
Rampant infrastructure projects ignoring ecological limits | Conduct carrying capacity studies before approving new projects |
Weak Environmental Impact Assessments (EIAs) | Ensure independent, transparent, and democratic public consultations |
Rising glacial risks and climate variability | Strengthen early warning systems and scientific monitoring |
Deforestation and soil erosion | Promote nature-based solutions, afforestation, and soil conservation |
Unsafe construction of schools, hospitals, and hotels | Enforce land-use zoning laws and prevent building on vulnerable sites |
Community exclusion in planning | Empower local self-governance, build climate literacy, and involve locals in disaster management |
Conclusion
The Himalayan floods of 2023 are not isolated natural events but outcomes of climate change compounded by unregulated development. The region’s fragile ecology demands a paradigm shift in planning that respects carrying capacity, prioritises disaster preparedness, and integrates community participation. Sustainable development, rooted in nature-based solutions, is the only way to secure both lives and livelihoods in the Himalayas.
EnsureIAS Mains Question Q. The Indian Himalayan region is facing increasing frequency and intensity of floods, landslides, and glacial lake outburst floods. Critically examine the role of climate change and unregulated development in aggravating these disasters. Suggest sustainable measures to balance development and ecological security. (250 words) |
EnsureIAS Prelims Question Q. Consider the following statements regarding Glacial Lake Outburst Floods (GLOFs): 1. GLOFs occur when a natural dam containing a glacial lake fails, releasing sudden floods downstream. 2. The Indian Himalayan region is witnessing faster temperature rise than the global average, increasing the risk of GLOFs. 3. All glacial lakes are stable and pose no risk of sudden outburst. Which of the above statements is/are correct? Answer: a) 1 and 2 only Explanation: Statement 1 is Correct: A GLOF happens when the moraine (natural dam of debris, ice, or rock) holding a glacial lake suddenly collapses, releasing a massive flood. Statement 2 is Correct: The Himalayas are warming faster than the global average, which increases glacier melting and formation of unstable lakes. Statement 3 is Incorrect: Not all glacial lakes are stable; some are highly dangerous due to weak moraine dams and shifting terrain. |
