• Mazagaon Dock Limited (MDL) in Mumbai

• ip has been constructed using innovative block construction methodology, wherein the ship’s hull has been assembled at distinct geographical locations before being integrated at the Mazagon Dock Limited(MDL).

• st of INS Surat depicts the renowned Hazira lighthouse. It was built in 1836, at the southern entrance of the Gulf of Khambhat. It was among India’s earliest lighthouses.

• crest also features an Asiatic lion (state animal of Gujarat) representing the majesty and strength of ships.

Ex- Bengaluru, Hyderabad and Chennai floods have occured due to encroachment of natural wetlands and construction of storm water drains in its place.

• unding and public investment– Large investments are needed in building artificial water conservation infrastructures.

• egular maintenance– Regular maintenance of these artificial structures is expensive and cumbersome as compared to natural conservation infrastructures like wetlands and forest.

• way forward in excess rain water management must be on the integration of green and grey infrastructures. But our focus must be on improving the green infrastructures first, as far as possible.
