Model Answer
India experiences heavy and unpredictable torrential rains, especially in the hilly regions, making landslide prevention difficult. The timing and intensity of rainfall are hard to predict, which complicates mitigation efforts. For instance, recent landslides in Kullu, Himachal Pradesh, highlighted the challenges posed by this unpredictability.
The young, evolving mountains of the Himalayan region, where many landslides occur, have fragile ecosystems. These regions are prone to landslides due to sedimentary deposits rather than solid rock, making mitigation efforts challenging.
Many major habitations and critical infrastructure are located near landslide-prone areas, which increases vulnerability. In Himachal Pradesh alone, there are 17,120 landslide-prone sites, with 675 near critical infrastructure.
Existing Landslide Susceptibility Management maps provide broad and generalized mitigation measures like “afforestation” without specifying which species of trees or plants to use or detailed biotechnical methods for slope stabilization.
There is a lack of comprehensive, state-wise or district-wise landslide hazard zonation maps, making effective planning and strategizing for disaster management difficult.
Role of the National Landslide Risk Management Strategy
The strategy aims to create detailed LHZ maps using advanced technology like Unmanned Aerial Vehicles (UAVs), terrestrial laser scanners, and high-resolution Earth Observation data. These maps will help in identifying and addressing high-risk zones.
The strategy emphasizes the development of monitoring systems, including rainfall thresholds, numerical weather prediction models, automatic rain gauges, and wireless sensor networks to provide early warnings.
It includes designing awareness programs, reviewing past efforts, and identifying gaps to ensure communities and stakeholders are better prepared for landslide risks.
The strategy outlines the need for capacity building and training programs for stakeholders on landslide disaster risk reduction (DRR) using the latest technology.
The strategy recommends updating building regulations, reviewing the BIS codes on landslide management, and revising town and country planning legislation to improve resilience in mountain zones.
By addressing these challenges and implementing the National Landslide Risk Management Strategy, India can improve landslide disaster preparedness and mitigation significantly.

Model Answer
Land-use change refers to human-induced modifications to the landscape, often for economic or developmental purposes. In India, rapid and often unsustainable land-use changes have heightened the frequency and intensity of natural disasters.
1. Urbanization and Concretization
Urbanization in India has led to the conversion of wetlands, forests, and hillslopes into impervious concrete surfaces. This disrupts natural drainage systems, increasing surface runoff, and exacerbating flooding. For instance, recent urban floods in cities like Mumbai, Delhi, and Kerala have been partly attributed to the encroachment of wetlands and deforestation, which had previously acted as natural flood buffers. Additionally, such land-use changes reduce groundwater recharge, making regions more vulnerable to droughts during dry spells.
2. Deforestation
The widespread deforestation to accommodate agricultural expansion and urban development contributes to the disruption of ecosystems that naturally regulate water flow. This has led to an increased risk of floods, soil erosion, and the occurrence of extreme weather events such as heatwaves and cyclones. Loss of forests also diminishes the resilience of local environments to climate change, thus intensifying the impacts of natural disasters.
3. Large-Scale Infrastructure Projects
Infrastructure projects, including large hydroelectric dams, roads, and railways, have resulted in habitat destruction and land degradation. For example, hydropower projects disrupt river ecosystems, potentially causing flash floods, Glacial Lake Outburst Floods (GLOFs), and landslides. Construction in mountainous areas, particularly for tourism, has led to significant landslides and road damage, as seen in Uttarakhand and Himachal Pradesh.
4. Coastal and Floodplain Construction
Illegal construction along floodplains and coastal areas increases exposure to flooding, coastal erosion, and storm surges. For example, unauthorized constructions in Punjab’s Ghaggar and Sutlej floodplains have led to devastating floods. Similarly, land reclamation in coastal areas makes communities more vulnerable to sea-level rise and tsunamis.
5. Agricultural Practices
Mono-cropping practices reduce crop diversity, making agriculture more susceptible to pests and diseases. This reduces food security and exacerbates vulnerability to droughts, contributing to economic and environmental disasters.
Conclusion
Sustainable land-use planning, including zoning regulations, reforestation, and comprehensive environmental impact assessments, is essential to mitigate the impact of these land-use changes and the natural disasters they fuel.

India’s Preparedness for Cyclone-Related Disasters
With a coastline of 7,516.6 kilometers, India faces nearly 10% of the world’s tropical cyclones, with five to six forming annually, and two to three being severe. Over the years, India has significantly enhanced its cyclone disaster management capabilities through various initiatives.
Improved Forecasting and Early Warning Systems
India has developed advanced cyclone forecasting through the India Meteorological Department (IMD), which accurately predicted cyclones like Phailin (2013), Fani (2019), and Amphan (2020). The IMD has implemented a color-coded cyclone warning system to improve public awareness and preparedness. Furthermore, collaboration with ISRO has strengthened weather monitoring using remote sensing satellites such as NAVIC and RESOURCESAT-2, which provide critical data on coastal conditions (Source: Indian Meteorological Department and ISRO).
Effective Evacuation and Relief Operations
India’s swift evacuation strategies during Cyclones Phailin and Fani saved thousands of lives. For instance, over a million people were safely evacuated during Cyclone Fani in 2019, an effort praised by the United Nations Office for Disaster Risk Reduction. The National Disaster Response Force (NDRF) has also been instrumental, providing timely rescue and relief work and maintaining a National Disaster Response Reserve with funds for emergency supplies (Source: United Nations Office for Disaster Risk Reduction).
Institutional Framework and Policy Initiatives
The National Disaster Management Authority (NDMA), established in 2005, has created comprehensive guidelines for cyclone management, while the National Cyclone Risk Mitigation Project (2011) focuses on enhancing tracking and early warnings in vulnerable states. Additionally, the National Disaster Management Plan, launched in 2016, aligns with the Sendai Framework, targeting disaster-resilient infrastructure and zoning (Source: National Disaster Management Authority).
Areas for Improvement
Despite these advancements, challenges remain. The current strategy emphasizes evacuation but overlooks other crucial aspects of disaster response, such as the pace of financial assistance distribution and the adequacy of post-disaster relief supplies. Increased focus on reconstruction funds, disaster risk audits in vulnerable regions, and better coordination between central and state governments would further strengthen India’s cyclone disaster management (Source: NDMA).
In summary, while India has made notable progress in reducing cyclone-related casualties, refining post-disaster recovery and resource distribution processes remains essential for comprehensive disaster management.
