India legally defined the concept of EEZ in the "Territorial Waters, Continental Shelf, Exclusive Economic Zone and Other Maritime Zones Act, 1976". In June 1997, India also ratified UNCLOS. India also enacted the "Maritime Zones of India (Regulation of fishing by foreign vessels) Act, 1981" prohibiting fishing by foreign vessel within Indian EEZ without a license. Additionally, India has also enacted laws regulation the fishing and fisheries by Indian fishing vessels operating in the EEZ.[5]
An EEZ provides a nation greater access to oil, natural gas, minerals, commercial fishing and other marine resources, freedom of navigation, international trade, national security, and strategic leverage over other nations.[4][5] With 7,500 km coastline and an EEZ of over 2.3 million km2, India has exclusive control over the resources in its EEZ including navigation of seafaring trade and transport vessels in this area.[5] As per 2014 study, India exploits only 3.2 million tonnes per year marine fishery resources out of potential 3.92 million tonne in its coastal areas.[5]
Piracy, poaching or illegal fishing by foreign vessels, freedom of navigation, transgression of foreign vessels into Indian EEZ, and conflicting claims are major issues in EEZ. Piracy in the Strait of Malacca is a major concern for all the nations. Studies have shown decline in fishing stocks and destruction of several marine ecological areas in Indian EEZ due to organized illegal poaching and fishing resulting in depletion of many endangered and threatened species. Freedom of the navigation has become a cause of concern due to piracy. National security is also threatened by actions of China around Indian EEZ. Conflicting claims over EEZ by nations leads to disputes, such as India-Pakistan Sir Creek dispute. In the past, UNCLOS has granted several contradicting claims while increasing the EEZ based on the evidence related to the length of continental shelf. These UNCLOS contradictions have resulted into overlapping EEZ claims by several nations competing for the resources in the expanded EEZ.[5]
