GS Mains Questions and Model Answers

Q1: Analyze the geographical features of the Lakshadweep Islands and their role in India’s maritime security.

Answer: The Lakshadweep Islands are a group of 36 coral islands located in the Arabian Sea. These islands form an archipelago off the southwestern coast of India, covering an area of about 30,000 square miles. Geographically, the islands are unique due to their coral atolls and vibrant marine life. Strategically, the Lakshadweep Islands play a crucial role in India’s maritime security. The islands serve as a key base for the Indian Navy to monitor and secure the vast shipping routes in the Arabian Sea. They also help protect India’s Exclusive Economic Zone (EEZ) and support naval operations in the Indian Ocean region. The strategic importance of the Lakshadweep Islands has led to their development as a major part of India’s security infrastructure in the Indian Ocean.

Q2: Discuss the environmental concerns associated with the island groups of the Arabian Sea, particularly the Maldives and Lakshadweep Islands.

Answer: The island groups of the Arabian Sea, particularly the Maldives and Lakshadweep Islands, face significant environmental concerns. These islands are highly vulnerable to the effects of climate change, particularly rising sea levels, which threaten to submerge low-lying areas. The Maldives, with its coral reefs, is also at risk due to coral bleaching caused by warming sea temperatures. The increasing frequency of tropical storms is another threat to the islands’ ecosystems. Furthermore, pollution, particularly plastic waste, and overfishing continue to strain the marine biodiversity of these islands. Efforts to preserve these islands' ecosystems include stricter environmental regulations, the promotion of sustainable tourism, and global initiatives to combat climate change.

Q3: Evaluate the strategic significance of the Andaman and Nicobar Islands for India’s security and global maritime interests.

Answer: The Andaman and Nicobar Islands hold immense strategic significance for India due to their location at the crossroads of important maritime routes in the Indian Ocean. Positioned between the Bay of Bengal and the Andaman Sea, the islands are a vital link for India’s maritime defense. They provide a critical base for the Indian Navy to monitor and control the region, ensuring India’s influence over key shipping lanes that pass through the Strait of Malacca. The proximity of these islands to Southeast Asia, China, and the eastern parts of the Indian Ocean adds to their strategic importance in terms of security and international diplomacy. The Indian government has invested in improving the infrastructure of these islands to enhance naval operations and strengthen India's defense capabilities in the Indo-Pacific region.
