Training, tech, Treaty commitments: CTBTO LAC workshop strengthens regional capacity

The Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) hosted a workshop for States Signatories from Latin America and the Caribbean (LAC) on 3-4 April, reaffirming the region’s collective commitment to a ban on nuclear testing.

The two-day event brought together more than 70 participants from 24 countries, alongside representatives from key regional and international organizations. These included the Agency for the Prohibition of Nuclear Weapons in Latin America and the Caribbean (OPANAL), the Association of Caribbean States (ACS), the Caribbean Community (CARICOM), and the Organization of American States (OAS).

The workshop was the second of its kind to focus on a specific region, aiming to deepen understanding of the Comprehensive Nuclear-Test-Ban Treaty (CTBT), highlight training and capacity building opportunities, and support countries in maximising the civil and scientific applications of the Treaty.

Speaking at the opening ceremony, CTBTO Executive Secretary Robert Floyd thanked Jamaica for hosting the event, stating: “I’m not only grateful for this opportunity, but also hopeful to see so many champions of our work and mission in one room. There is such a power of voice when you stand as one.”

Jamaica’s Minister of Foreign Affairs and Foreign Trade, Kamina Johnson Smith, emphasised the country’s long-standing support: “Jamaica remains resolute in our commitment to the Treaty and the work of the Organization, and this is reaffirmed by our decision to host this regional workshop.”

She continued: “I encourage you to seize the opportunity not only to expand expertise, but also to cultivate strong networks and lasting partnerships.”

Kristen Ferguson, an analyst at Jamaica’s Ministry of National Security and member of the CTBTO Youth Group (CYG), also took part - representing the growing voice of young professionals working towards a safer, more secure global future.

Sessions during the workshop offered a technical overview of the CTBT’s verification regime and introduced some of the participants to the CTBTO’s National Data Centres-for-All (NDCs4All) initiative. Attendees explored how data from seismic, hydroacoustic, infrasound, and radionuclide technologies can be used to support disaster preparedness, climate research and other scientific priorities.

One session focused on helping States in the region establish or strengthen their NDCs. These facilities are key to ensuring that CTBTO data can be received, analysed, and applied effectively at the national level.

During the event, the CTBTO partnered with regional media to enhance visibility and engagement. Journalists from Argentina, Barbados, Brazil, Grenada, Guyana, and Trinidad and Tobago were invited to attend, helping to ensure broader and more balanced coverage across the region. Their reporting translated diplomatic and scientific information into accessible stories for wider public audiences.

The workshop in Jamaica followed a similar event held in The Gambia in 2024, which focused on African States. The next regional workshop will be held in 2026, and will focus on the Asia-Pacific.
