The Pune-based Maritime Research Centre (MRC) has achieved a milestone by submitting an interim report on a proposed national capacity- and capability-building policy to bring about effective Underwater Domain Awareness (UDA). This is a ‘whole-of-nation’ approach to bring all the stakeholders in UDA together, feels the founder-director of MRC, Dr (Cdr) Arnab Das, who presented it to NITI Aayog CEO Amitabh Kant in Delhi last week. Kant is understood to have appreciated MRA’s continued efforts in taking the UDA framework forward. The project had started with a presentation to the NITI Aayog Vice Chairman Dr Rajiv Kumar and four Advisors. Cdr Das also had the opportunity to meet Milinda Moragoda, High Commissioner of Sri Lanka to India, and brief him on the UDA framework and its importance for Indo-Sri Lanka relationships. The increasing maritime activities in the Indian Ocean Region lead to higher noise levels, affecting marine species that use sound for multiple biologically critical functions like foraging, navigation, communication and finding mates. The sensing of the undersea domain for threats, resources and activities, making sense of the data generated for security strategies, conservation plans and resource utilisation plans are vital; and the MRC is keen to play a major role in this critical national and regional initiative.
