Climate change is likely to influence maritime security in the Indian Ocean Region (IOR). The growing unpredictability in climate and weather patterns is having a disproportionate impact over the region. Not only is the IOR predicted to bear the brunt of future climatic changes, it is also likely to face strong constraints in meeting the coming threats. The effect of climate change on human security in the IOR is only likely to be matched by the impact of extreme weather conditions on naval operations and the security of maritime assets.

The Maritime Silk Road (MSR) idea is part of this wider attempt by China to construct multiple lines of communication to its economic heartland in eastern China since the early 2000s. The underlying aim of such a geostrategy is to also develop inner Chinese provinces and shape China’s regional periphery by exercising economic, political and cultural Influence.

Maritime security in the Indian Ocean Region (IOR) is a central issue for regional and extra-regional actors. Traditional and non-traditional security challenges largely converge at sea as they impact economic, environmental, energy, human, food and national security. As the major regional power and an emerging Asian great power, India’s willingness and capacity to provide strategic leadership is critical to engendering a cooperative spirit of shared destiny. India’s growing naval capabilities indicate a strong commitment to maritime security.

Maritime strategic planning cannot be done in isolation of marine eco-concerns. Marine species are known to perceive the environment around them through acoustic signals, and depend on sound for numerous functions like foraging, communication and navigation. Noise as a pollutant has found scant reference in the United Nations Environmental Programme (UNEP) document of 1982—the United Nations Convention on the Laws of the Seas (UNCLOS). The International Maritime Organization (IMO) is yet to include noise as a pollutant in its 1978 MARPOL Convention.

The return of piracy to the Indian Ocean in modern times has culminated in the resurgence of the private violence industry in the maritime domain. For the first time in modern history, the private military security industry will work alongside traditional navies on the field. The dynamics between the two major security actors in the anti-piracy operations make for an interesting study. This article argues that there exists much potential for fruitful engagement between the two actors: PMSCs and navies.
