Representatives from 12 nations, including France and Indonesia, participated in simulating coordinated responses to non-traditional threats like maritime terrorism, piracy, and illegal trafficking.

Explanation: Scotland became the first UK nation to legally approve the use of alkaline hydrolysis, commonly known as water cremation, resomation, or aquamation. Effective from March 2026, this legislation modernizes funeral options by offering an end-of-life practice that has a significantly lower carbon footprint compared to traditional gas-fired flame cremation.

Explanation: The water cremation (aquamation) process utilizes a strong solution of water and an alkali, typically potassium hydroxide. The system operates under pressure and is heated to approximately 150-180°C. This combination safely and rapidly accelerates the body’s natural decomposition, ultimately reducing the remains to bone fragments and a sterile liquid.
