Initial trials of the new bio-concrete technology have been conducted in the Great Barrier Reef and the Maldives, demonstrating significant improvements in coral recruitment and growth.

While coral reefs are incredibly biodiverse and provide crucial ecosystem services, their direct contribution to atmospheric oxygen production is minimal compared to phytoplankton and terrestrial plants.

The bio-concrete is engineered to be a living substrate, mimicking natural calcium carbonate and containing microbial communities that actively encourage coral larval settlement and growth, thus accelerating the reef-building process.

While other factors contribute, ocean warming leading to coral bleaching is the most significant and widespread threat to coral reefs globally, driven by climate change.

Cooperation in military exercises like 'Ajeya Warrior' helps both nations to better address global security challenges and contribute to regional and international stability.

The primary goal of such joint exercises is to improve the ability of the participating armies to work together effectively (interoperability) and build mutual understanding.

The drills simulated scenarios involving asymmetric threats such as ambushes, IED detection and disposal, and room intervention tactics.

The 2026 edition of 'Ajeya Warrior' specifically focused on joint planning and execution of counter-insurgency and counter-terrorism operations.

'Ajeya Warrior' is a bilateral joint military exercise conducted between the Indian Army and the British Army.

Increased range and endurance enable the drone to cover larger operational areas and provide continuous surveillance, which is vital for monitoring and intelligence gathering.
