Himalayan glaciers are a crucial source of water for major river systems in Asia. Their accelerated melt threatens long-term water security for millions who depend on these rivers for drinking water, irrigation, and hydropower.

CREM directly contributes to India's efforts in climate change adaptation by strengthening coastal ecosystems against extreme weather events and supports biodiversity conservation by protecting critical marine habitats.

CREM focuses on ecosystem restoration, which includes activities like mangrove plantation, coral reef conservation, and protection of other critical coastal habitats to build natural resilience.

The Coastal Resilience & Ecosystem Restoration Mission (CREM) aims to strengthen coastal defense mechanisms and restore degraded marine and coastal ecosystems, such as mangroves and coral reefs, to enhance resilience against climate change impacts.

The combination of extreme speed and maneuverability makes hypersonic missiles extremely difficult for current air defense systems to intercept.

Hypersonic missiles travel at speeds greater than Mach 5 (five times the speed of sound).

The Defence Research and Development Organisation (DRDO) is responsible for developing India's strategic missile systems.

Varuna exercises are typically conducted in the Indian Ocean Region to ensure maritime security.

The exercise aims to strengthen bilateral cooperation and enhance interoperability between the two navies.
