There are important changes in regional and global demographics ahead of us. A profound rise in the number of citizens in the Indian Ocean Region in the next fifty years will have significant impacts on the state, on the nature and operation of markets and the neo-liberal framework they operate in, and raise new challenges for regional security. This book considers the insufficient dialogue between ever increasing and closer connections between geo-economics and geo-securities in the Indian Ocean Region, and highlights some of the challenges. This book takes a broader understanding of security than what is usually meant in more traditional security frameworks in politics and international relations. Economic and politics are integrally, and obviously, related. This book considers regional themes such as discourses around strategic competition; models of regional cooperative security; Indian Ocean Region domestic economies/ contexts and the military industrial complex; and regional models of identity and cultural belonging. Regions and regionalisms are increasingly being used to challenge power, and the existence of any uniform model of macro-politics and macro-economics (whether it be neo-liberalism or otherwise). Most importantly, these discussions of region enable us to celebrate the similarities that we share as neighbours (in a real geographical sense) and to comprehend and respect these differences in these rich regional communities of markets, cultures, and securities. This book was previously published as a special issue of the Journal of the Indian Ocean Region.
