Book excerpt: This book deals with the various interdisciplinary issues of the Indian Ocean, individually and collectively, such as its history, geography, nautical elements, economics, trade routes (old and new), blue economy, deep-sea mining, fisheries management, tourism, scourge of piracy, pollution, Law of the Sea (UNCLOS 1982), and the different perspectives of its littoral countries on geopolitics, international law, international relations and maritime partnerships. It is the most important ocean in the world – 33% of the global population lives in the area and 50-60% of the world’s maritime trade transits through it. In addition, around 60% of global oil, and 26% of global gas reserves, along with pristine beaches are located here. To comprehend the interdisciplinary issues, the editor embarked on a voyage to discover, persuade and collaborate with exceptionally brilliant, influential experts from prominent littoral countries – India, Indonesia, Iran, South Africa, Malaysia and Singapore – with relevant experience to expound the above subject areas. In addition, geopolitical conflicts/hostilities and trade wars are on the rise; war seems inevitable but not imminent. Any conflict is likely to originate in other oceans and seas but will end up impacting the Indian Ocean’s littoral countries. Accordingly, these countries must comprehend the interdisciplinary issues and the special role of the Indian Ocean to prevent all-encompassing wars/hostilities from widening at a global level and thereafter must flesh out plans to shield themselves. They must also understand the area’s role in working towards global peace by comprehending the above interdisciplinary issues. The role of the Indian Ocean in global peace can only be achieved through maritime partnerships between its littoral countries, and their avoidance of impulses to invite outside power(s) to balance each other’s power. However, maritime partnerships are easier said than done. At the very least, the maritime partnership between two major Indian Ocean littoral powers – India and Indonesia – is critical to shield the region from geopolitical firestorms. Hopefully, this maritime partnership’s tactic of embracing a carrot-and-stick approach will eventually persuade global powers from outside the Indian Ocean region to improve their conduct to achieve global peace.
