The blue economy is a concept that recognizes the economic potential of oceans and other water resources. In India, the blue economy faces several challenges, including overfishing, habitat degradation, pollution, rising sea levels, and climate change. To audit the blue economy in India, new techniques must be adopted, including:

• Remote sensing technologies for monitoring water quality, fish stocks, and ocean habitats
• Use of drones for surveying and monitoring ocean resources
• Integration of marine spatial planning to ensure sustainable development of the coastal zone
• Developing a comprehensive database on marine resources and ecosystem services

Auditing the blue economy in India requires a shift towards sustainable development that balances economic growth with conservation of marine resources. Addressing these challenges through effective strategies and new technologies can lead to a thriving blue economy that contributes to India's economic and social development.
