Cyclone Ditwah has brought torrential downpours, leading to widespread flooding and significant crop damage in the southern coastal and delta districts of Tamil Nadu. Residential areas and salt pans were inundated, and north-coastal areas, including Chennai, are on high alert for strong winds and heavy rainfall. Meanwhile, the cyclone's impact has been far more severe in Sri Lanka, where the death toll has tragically risen to 159, with 203 people still missing.
Sri Lankan President Anura Kumara Dissanayake has declared a state of emergency to accelerate rescue and relief operations. This event underscores the increasing frequency and intensity of extreme weather events, highlighting the critical need for robust disaster management and climate change adaptation strategies in the region.

More Information
Background
Tropical cyclones are intense low-pressure systems forming over warm tropical oceans, characterized by strong winds and heavy rainfall. The Bay of Bengal is one of the most active regions for cyclone formation globally, particularly during the pre-monsoon (April-June) and post-monsoon (October-December) seasons.
India and Sri Lanka, with their extensive coastlines, are highly vulnerable to these events. Historically, major cyclones have caused immense loss of life and property in the region, leading to the development of sophisticated early warning systems and disaster management frameworks.

Practice Questions (MCQs)
1. Consider the following statements regarding tropical cyclones in the Indian Ocean region: 1. Cyclone Ditwah, which recently impacted South India and Sri Lanka, originated in the Bay of Bengal. 2. The frequency of tropical cyclones forming in the Arabian Sea is generally higher than in the Bay of Bengal. 3. Post-monsoon cyclones in the Bay of Bengal typically form during October-November and often move towards the east coast of India. Which of the statements given above is/are correct?
- A.1 only
- B.1 and 3 only
- C.2 and 3 only
- D.1, 2 and 3
Show Answer
Answer: B
Statement 1 is correct as per the news and general cyclone patterns. Statement 2 is incorrect; the Bay of Bengal experiences a significantly higher number of cyclones compared to the Arabian Sea due to various factors like higher sea surface temperatures, freshwater influx, and geographical configuration. Statement 3 is correct; the post-monsoon season (October-December) is a peak period for cyclone activity in the Bay of Bengal, and these cyclones frequently make landfall on India's east coast.
2. In the context of the recent declaration of a state of emergency in Sri Lanka due to Cyclone Ditwah, consider the following statements regarding disaster management in India: 1. The National Disaster Management Authority (NDMA) is chaired by the Prime Minister of India. 2. A 'state of emergency' can be declared by the President of India under Article 352 of the Constitution in cases of natural calamity. 3. The National Disaster Response Force (NDRF) is a specialized force under the Ministry of Home Affairs for disaster response. Which of the statements given above is/are correct?
- A.1 and 2 only
- B.1 and 3 only
- C.2 and 3 only
- D.1, 2 and 3
Show Answer
Answer: B
Statement 1 is correct; the Prime Minister is the ex-officio Chairperson of the NDMA. Statement 2 is incorrect; Article 352 of the Indian Constitution pertains to National Emergency declared on grounds of war, external aggression, or armed rebellion, not directly for natural calamities. While natural calamities can lead to severe disruptions, India's disaster response is primarily governed by the Disaster Management Act, 2005, which provides for specific mechanisms like declaring a 'disaster' but not a 'state of emergency' under Article 352. Sri Lanka's declaration is under its specific laws. Statement 3 is correct; the NDRF is indeed a specialized force under the Ministry of Home Affairs, constituted under the DM Act, 2005, for specific disaster response duties.
3. With reference to climate change strategies, consider the following statements: 1. Building cyclone-resistant infrastructure and advanced early warning systems are examples of climate change mitigation strategies. 2. Reducing greenhouse gas emissions through renewable energy adoption is a key component of climate change adaptation. 3. The Sendai Framework for Disaster Risk Reduction primarily focuses on reducing existing disaster risk and preventing new risks. Which of the statements given above is/are correct?
- A.1 only
- B.3 only
- C.1 and 2 only
- D.2 and 3 only
Show Answer
Answer: B
Statement 1 is incorrect. Building cyclone-resistant infrastructure and early warning systems are examples of climate change *adaptation* strategies, aimed at reducing vulnerability and coping with the impacts of climate change. Mitigation strategies aim to reduce the causes of climate change. Statement 2 is incorrect. Reducing greenhouse gas emissions through renewable energy adoption is a key component of climate change *mitigation*, as it addresses the root cause of global warming. Adaptation focuses on adjusting to the actual or expected future climate. Statement 3 is correct. The Sendai Framework for Disaster Risk Reduction (2015-2030) is a global agreement that emphasizes reducing existing disaster risk, preventing new risks, and strengthening resilience.
