Tonga has entered into a renewed sponsorship agreement with Tonga Offshore Mining Ltd (TOML), a subsidiary of the Canadian entity, The Metals Company (TMC), to explore the mineral-rich Clarion Clipperton Zone (CCZ) between Hawai’i and Mexico. This move has ignited debate amidst heavy criticism from NGOs and local communities regarding the potential legal and environmental ramifications for Tonga, a central sponsor state for TMC.
The updated agreement builds on a five-year relationship and grants TOML the ability to conduct research activities in the CCZ, specifically without engaging in mining in Tonga’s direct waters. Dr. ‘Uhilameilangi Fasi, Tonga’s Minister of Lands and Survey, clarified that the agreement covers environmental considerations in the CCZ distinct from those of Tongan waters.
Despite the lack of direct risk to Tonga’s waters, marine scientist Tu’amelie Fusimalohi voices concerns over possible financial and legal liabilities if environmental damage occurs. Drawing parallels to the failed Solwara 1 project in Papua New Guinea, Fusimalohi stresses the need for robust performance bonds, explicit monitoring mechanisms, and fair revenue-sharing provisions to protect Tonga’s interests.
While the ecological risks to Tonga may be minimal due to geographical distance, shared oceanic resources such as migratory tuna could be impacted by activities in the CCZ. TMC’s expertise lies in extracting polymetallic nodules, abundant in the CCZ, that are essential for renewable energy technologies.
Under the United Nations Convention on the Law of the Sea (UNCLOS), states like Tonga have the right to hold exploration contracts in areas like the CCZ which lie outside national jurisdictions. However, the agreement’s opacity and lack of public consultation have raised concerns.
The situation highlights the broader debates facing Pacific nations as they navigate the delicate balance between exploiting economic opportunities from mining and the imperative to protect fragile marine ecosystems. The push for sustainable management of ocean resources continues to gather momentum, advocating a cooperative regional strategy that ensures environmental caution.
This scenario underscores the larger environmental and economic challenges Pacific nations face in managing oceanic resources that are vital for both biodiversity and their economic potential. It emphasizes the importance of inclusive dialogue focused on sustainable growth alongside marine ecosystem preservation. A balanced approach can lead Tonga and its neighbors towards a future where prosperity and environmental health coexist, safeguarding natural treasures for future generations.
