The Convention on the Law of the Sea (UNCLOS), which was developed under the supervision of the United Nations and ratified in 1982 by 117 States, is the international instrument most frequently linked to the law of the sea. UNCLOS came into force in 1994. UNCLOS is a framework Convention that addresses a wide range of ocean-related issues. The treaty, which is divided into seventeen parts and nine appendices, outlines states’ rights and responsibilities with regard to: (1) the territorial sea and contiguous zone; (2) straits used for international navigation; (3) archipelagic states; (4) the exclusive economic zone; (5) the continental shelf; (6) the high seas; (7) the regime of islands; (8) enclosed or semi- enclosed seas; (9) the right of access of landlocked states to and from the sea and freedom of transit.
UNCLOS establishes guidelines for all uses of the oceans’ resources and establishes a comprehensive regime of law and order throughout the world’s oceans and seas. It encapsulates long-standing guidelines for using the oceans in one document while also introducing new legal frameworks and addressing fresh issues. The Convention also lays forth the groundwork for future advancements in particular spheres of maritime law. The United Nations Convention on the Law of the Sea (UNCLOS) establishes guidelines for using the ocean and its resources, but it is silent on how governments should specifically, save for broad provisions, protect and sustainably utilise biodiversity found in the high seas. States are able to identify their jurisdictional waters and maritime zones by establishing a coastal baseline;200 nautical miles from the baseline are included in their Exclusive Economic Zone (EEZ). The resources present in the zone may only be utilised or conserved by States.
The term “Areas Outside National Jurisdiction” refers to the portions of the ocean outside the Exclusive Economic Zone The water column, also known as the High Seas, and the seabed, sometimes known as the Area, are further divisions of these regions according to the Law of the Sea. Thus, currently there is no comprehensive set of rules to ensure their conservation and sustainable use. Notably, UNCLOS provides that ‘all States have the duty to take, or to cooperate with other States in taking, such measures for their respective nationals as may be necessary for the conservation of the living resources of the high seas’. UNCLOS uses the term ‘high seas’ to mean ‘all parts of the sea that are not included in the exclusive economic zone, in the territorial sea or in the internal waters of a State, or in the archipelagic waters of an archipelagic State’. It also states that ‘the high seas are open to all States, whether coastal or land-locked.
Freedom of the high seas is exercised under the conditions laid down by this Convention and by other rules of international law. It comprises, inter alia, both for coastal and land-locked States: (a) freedom of navigation; (b) freedom of overflight; (c) freedom to lay submarine cables and pipelines, subject to Part VI; (d) freedom to construct artificial islands and other installations permitted under international law, subject to Part VI; (e) freedom of fishing, subject to the conditions laid down in section 2; and (f) freedom of scientific research, subject to Parts VI and XIII. These freedoms are to be exercised by all States with due regard for the interests of other States in their exercise of the freedom of the high seas, and also with due regard for the rights under this Convention with respect to activities in the Area.
UNCLOS also states that ‘States shall cooperate with each other in the conservation and management of living resources in the areas of the high seas. States whose nationals exploit identical living resources, or different living resources in the same area, are obligated to enter into negotiations with a view to taking the measures necessary for the conservation of the living resources concerned. They are to, as appropriate, cooperate to establish sub-regional or regional fisheries organizations to this end.
Regarding conservation of the living resources of the high seas, UNCLOS provides that ‘in determining the allowable catch and establishing other conservation measures for the living resources in the high seas, States shall: (a) take measures which are designed, on the best scientific evidence available to the States concerned, to maintain or restore populations of harvested species at levels which can produce the maximum sustainable yield, as qualified by relevant environmental and economic factors, including the special requirements of developing States, and taking into account fishing patterns, the interdependence of stocks and any generally recommended international minimum standards, whether sub-regional, regional or global; and (b) take into consideration the effects on species associated with or dependent upon harvested species with a view to maintaining or restoring populations of such associated or dependent species above levels at which their reproduction may become seriously threatened.
As far as the principles governing the area are concerned, UNCLOS provides that ‘necessary measures shall be taken in accordance with this Convention with respect to activities in the Area to ensure effective protection for the marine environment from harmful effects which may arise from such activities. To this end the International Seabed Authority shall adopt appropriate rules, regulations and procedures for inter alia: (a) the prevention, reduction and control of pollution and other hazards to the marine environment, including the coastline, and of interference with the ecological balance of the marine environment, particular attention being paid to the need for protection from harmful effects of such activities as drilling, dredging, excavation, disposal of waste, construction and operation or maintenance of installations, pipelines and other devices related to such activities; and (b) the protection and conservation of the natural resources of the Area and the prevention of damage to the flora and fauna of the marine environment.
UNCLOS outlines States’ general obligation to protect and preserve the marine environment. In order to move away from these generalized duties under UNCLOS and which mainly focuses on the jurisdictions of States, the High Seas Treaty is meant to come into force to define specific environmental duties relating to the high seas. The background to this new development is that UNCLOS is best understood as a framework providing a basic foundation for the international law of the oceans intended to be extended and elaborated upon through more specific international agreements and the evolving customs of States.
