UNCLOS, Exclusive Economic Zones & Blue Economy
The United Nations Convention on the Law of the Sea (UNCLOS), adopted in 1982, establishes the international legal order governing ocean territories, navigation, and resource exploitation. It defines clear maritime zones measured from territorial baselines: Internal Waters, Territorial Sea (up to 12 nautical miles), Contiguous Zone (up to 24 nautical miles), Exclusive Economic Zone (EEZ, up to 200 nautical miles), and the High Seas beyond national jurisdiction. Within its EEZ, a coastal state exercises sovereign rights over living and non-living natural resources. India's Blue Economy policy emphasizes sustainable coastal shipping, marine tourism, offshore energy, mariculture, and deep-sea mineral exploration while adhering to International Seabed Authority mandates for the international seabed Area.
