An innovative initiative to establish a global ranking of the most peaceful nations is being launched in April by founder Steve Killelea and the statistical team from The Economist Group. Steve was driven to creating the World Peace Index (WPI) after he posed the simple questions of which countries were the most peaceful and which were not. As an international businessman, who successfully launched two major software firms from Sydney, Australia, he pondered this question among many experts, all of whom could not provide an objective and satisfactory response. Killelea is funding the initial creation of the WPI, while amassing a host of institutions and individuals, including the Dalai Lama, the Sydney Peace Foundation, the Institute for Multi-Track Diplomacy, Columbia University, and the Alliance for Peacebuilding. The sustainability of the initiate is critical to acceptance of the Index as a rallying point for internal and international dialogs. Killelea believes that the Digital Earth community is crucial to disseminate the WPI, but more importantly to create an upwelling of local information for updating and fine-tuning the WPI. Local relevance is mandatory for usefulness. Mr. Killelea will be keynoting this revolutionary World Peace Index at the ISDE5.
