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.

Formation of Cloudbursts
Cloudbursts are intense, localized rainfall events that typically occur in hilly regions. They are characterized by a rapid, heavy downpour of over 100 mm of rain in an hour, as defined by the Indian Meteorological Department (IMD). These events primarily occur in areas like the Himalayan states, where specific topographic and meteorological conditions prevail.
The process of cloudburst formation begins when moisture-laden air ascends a hilly terrain. This upward movement, known as “orographic lift,” causes the air to cool and form a vertical column of cumulus clouds. The rising air keeps raindrops suspended within the clouds, allowing new droplets to form and existing ones to grow larger. Lightning further delays rainfall within the clouds. Eventually, when these clouds can no longer hold the accumulated moisture, they burst, leading to intense and localized rainfall in a small geographical area of about 20 to 30 square kilometers.
Impact of Cloudbursts
Measures to Mitigate the Impact
To reduce the effects of cloudbursts, several measures can be adopted:
By combining these strategies, the devastating effects of cloudbursts can be minimized, ensuring better preparedness and response in vulnerable areas.

India’s Vulnerability to Natural Disasters: A Detailed Discussion
India’s diverse geo-climatic conditions make it one of the most disaster-prone countries in the world. According to the National Institute of Disaster Management (NIDM), 27 out of India’s 36 states and union territories are susceptible to natural disasters. The country’s vulnerability is heightened by various factors, including its geographical location, climatic conditions, and socio-economic factors.
Earthquakes
India is situated on the Alpine-Himalayan Belt, where the Indian Plate meets the Eurasian Plate, making it highly prone to earthquakes. Fourteen states in India, including regions like the Andaman and Nicobar Islands, Gujarat, and parts of the North-East, are at high seismic risk. For example, the 2001 Gujarat earthquake caused significant destruction, resulting in numerous casualties and extensive damage to infrastructure. According to NIDM, 58.6% of the country’s land is at risk from earthquakes of moderate to very high intensity.
Floods
Flooding is another major disaster, affecting approximately 12% of India’s land area (40 million hectares). This is largely due to heavy monsoon rainfall, which contributes to floods every year, particularly between June and September. States like Kerala, Assam, and Bihar frequently experience severe floods. The 2018 Kerala floods, for example, caused widespread devastation, with the loss of lives and infrastructure.
Cyclones and Tsunamis
India’s long coastline of 7,516 km is vulnerable to cyclones and tsunamis, especially along its eastern coast. Around 71% of the coastline, including states like Odisha, West Bengal, and Andhra Pradesh, is prone to these natural disasters. The eastern coast experiences nearly 10% of the world’s tropical cyclones. The 2004 Indian Ocean tsunami and the 1999 Odisha cyclone are notable examples of the devastation caused by such events.
Droughts and Heatwaves
Around 68% of India is prone to drought, with chronic drought conditions affecting areas like Rajasthan, Gujarat, and parts of Maharashtra. In addition, heatwaves are increasingly common, especially in northern and central India, with states like Punjab, Uttar Pradesh, and Rajasthan experiencing extreme temperatures during summer months.
Landslides
Landslides are frequent in regions like the Western Ghats, the Himalayas, and the Andaman Islands due to high rainfall and seismic activity. For instance, the 2013 Uttarakhand floods and landslides caused widespread destruction and loss of life.
Conclusion
India’s unique geo-climatic conditions expose it to a wide range of natural disasters, from earthquakes and cyclones to floods, droughts, and heatwaves. The government has recognized this vulnerability by establishing the National Disaster Management Authority (NDMA) to address these challenges and prepare for disaster resilience.
