Governments, industry executives and international organizations have expressed support for strengthening the world's vital undersea network of telecommunications cables at the International Submarine Cable Resilience Summit in Abuja, Nigeria.
The concluding Summit Declaration , developed by the International Advisory Body on Submarine Cable Resilience, includes a commitment to international efforts to reinforce submarine telecommunications cable resilience, centred on actions ranging from increased cooperation to technical advancements.
More than 99 per cent of international data traffic is carried by a network of about 500 submarine telecommunications cables spanning over 1.7 million kilometres worldwide. With an average of 150 to 200 faults reported globally each year, disruptions to communications affect economies, access to information and public services, as well as the daily lives of billions of people.
"Submarine telecommunications cables are a fundamental backbone of our interconnected world. Entire economies feel the impact of disruptions to service," said ITU Secretary-General Doreen Bogdan-Martin. "This summit is galvanizing global efforts to ensure the resilience of this vital telecommunications infrastructure."
The two-day event was organized by Nigeria's Ministry of Communications, Innovation, and Digital Economy, in partnership with the International Telecommunication Union (ITU) and the International Cable Protection Committee (ICPC).
The Summit Declaration promotes global cooperation on key areas including:
- Strengthening cable protection through risk mitigation;
- Promoting diverse routes and landings to enhance resilience and continuity;
- Facilitating timely deployment and repair.
The declaration also includes a recognition that advancing sustainable approaches, fostering technological innovation, and facilitating capacity building are essential for addressing global challenges and driving inclusive development, with a strong emphasis on preparing for both present and future connectivity needs.
"With submarine cables forming the lifelines of the digital age, strengthening their resilience is a shared priority," said H.E. Minister Bosun Tijani, Minister of Communications, Innovation and Digital Economy of the Federal Republic of Nigeria and Co-Chair of the Advisory Body. "This summit and its declaration underscore our commitment to safeguarding the infrastructure that our digital economy is built upon. As a key landing point for submarine cables in Africa, Nigeria is well-placed to contribute to and help shape global efforts to enhance resilience."
"This is a key moment for submarine cable resilience as this declaration clears the way for greater international cooperation," said Prof. Sandra Maximiano, Chair of ANACOM and Co-Chair of the Advisory Body. "Given the importance of submarine cables in connecting Portugal, particularly our Autonomous Regions of Madeira and the Azores, and our strategic position for landing transcontinental cables, this declaration represents a major development for us. I believe it is an important achievement for the entire submarine cable ecosystem."
The summit featured the first in-person meeting of the International Advisory Body on Submarine Cable Resilience formed by ITU in partnership with the ICPC in late 2024 . The Advisory Body aims to help strengthen the operational resilience of submarine cables, supporting reliable connectivity for all.
"This summit brought together the global submarine cable industry and governments to focus on the continued protection and resilience of this critical infrastructure," said ICPC Chairman Graham Evans. "This cooperation provides a key opportunity to work together on the practical steps to promote best practices to enhance the resilience of submarine cables across the world."
Advisory Body decisions at the summit include the formation of working groups focused on risk identification, monitoring and mitigation, as well as connectivity and geographic diversity of landing points and routes, and timely deployment and repair of cables.
