Archives (PRELIMS & MAINS Focus) Andaman and Nicobar Islands Syllabus Prelims & Mains – Geography, Security challenges Context: Various geopolitical events leading to the realisation of the critical importance of ocean power, the rapid enhancement in the capabilities of the Chinese PLA Navy, and the transformation of India’s Look East policy into a robust Act East policy have brought new thrust to developing Indian island territories in general and the Andaman and Nicobar groups in particular. Background:- The Andaman and Nicobar (A&N Islands) islands are located 700 nautical miles (1,300 km) southeast of the Indian mainland. Key takeaways Andaman and Nicobar islands share four of India’s international maritime zone delimitations with Myanmar, Thailand, Indonesia, and Bangladesh. They also give India substantial ocean space under the United Nations Conference on the Laws of the Sea (UNCLOS) in terms of exclusive economic zone and continental shelf. The Malacca Strait, the main waterway that connects the Indian Ocean to the Pacific, is less than a day’s steaming from Port Blair. The severe disruption and re-routing of shipping, occasioned by the Houthi attacks in the Red Sea, have served as yet another harsh and expensive reminder that “maritime choke points” constitute critical vulnerabilities for world trade and commerce. In this context, the Malacca Strait — more than 90,000 merchant ships carrying about 30 per cent of the world’s traded goods pass through it every year — presents a challenge as well as a latent opportunity for India. The Andaman and Nicobar Islands are of great strategic importance since they straddle one of the busiest sea lanes in the world and give India the reach to monitor the flow of traffic from the South China Sea (Pacific Ocean) to the Andaman Sea (Indian Ocean) via the Strait of Malacca that’s key to trade and oil shipments in the Indo-Pacific. Of significance for Indian strategists is the location of the Great Nicobar Island, which sits astride the western entrance/exit of the Malacca Strait and can comprehensively dominate all shipping — merchant as well as naval — in transit. The A&N Islands should be the first line of offence against any attempt from the East to undermine India’s maritime security. While some effort was made to leverage this locational advantage with the Andaman and Nicobar Command (ANC) being constituted as a tri-services command in 2001, subsequent efforts have been grossly inadequate. Reasons for the Slow Pace of Infrastructural Development in the A&N Islands: Distance from the mainland and difficulties in developing infrastructure. Complex procedures for obtaining environmental clearances. Significant coordination challenges among ministries, departments, and agencies. Key areas to be focused on for the development of the A&N Islands: Development of separate airfields with long runways for monitoring and patrolling of sea areas by aircraft and surface platforms. Work on the Galathea Bay (Great Nicobar Island) transhipment port must be expedited. Maritime services such as repair and logistics must be developed for international and Indian shipping. Road networks, high-speed inter-island ferry services, and a seaplane terminal. Forest and environmental clearances must be accorded with minimum red tape. Planned habitation of uninhabited islands should be considered by providing incentives. Eco-friendly entrepreneurial efforts could be encouraged.

But sometimes changes in the patterns of winds and ocean currents cause seawater to suddenly cool, instead. Background: When a “killer coldwave” manifested along South Africa’s southeast coast in March 2021, it killed hundreds of animals across at least 81 species. More worrying still was the fact these deaths included vulnerable manta rays and even specimens of notoriously robust migratory bull sharks. About Cold waves Sometimes changes in the patterns of winds and ocean currents cause seawater to suddenly cool. Surface temperatures can plummet rapidly — by 10ºC or more over a day or two. When these conditions persist for several days or weeks, the area experiences a “coldwave”. Certain wind and current conditions can cause the sea surface to cool, rather than warm. This happens when winds and currents force coastal waters to move offshore, which are then replaced from below by cold water from the deep ocean. This process is known as In some places, such as California on the US west coast, upwelling happens regularly along hundreds of kilometres of coastline. But localised upwelling can occur seasonally on a smaller scale, too, often at the edges of bays on the east coasts of continents due to interactions of wind, current and coastline. Previous research had shown climate change induced changes in global wind and current patterns. Studies reveal an increasing trend in the number of annual upwelling events over the past 40 years. We also found an increase in the intensity of such upwelling events and the extent to which temperatures dropped on the first day of each event – in other words, how severe and sudden these cold snaps were. During the extreme upwelling event along the southeast coast of South Africa in March 2021, at least 260 animals from 81 species died. These included tropical fish, sharks and rays. Overall, our oceans are warming. The ranges of tropical and subtropical species are extending towards the poles. But along some major current systems, sudden short-term cooling can make life difficult for these climate migrants, or even kill them. This really shows the complexity of climate change, as tropical species would expand into higher-latitude areas as overall warming continues, which then places them at risk of exposure to sudden extreme cold events.
