Once viewed as peripheral security threats, issues of health, environment, crime, migration, poverty, among others are increasingly central to international peace and security. These problems pose unprecedented challenges for the international community in an increasingly globalized world. While conventional approaches to global security, centering on interstate conflict and civil war, continue to threaten regions that are institutionally and economically weak and susceptible to disruption, a broader approach to global security is increasingly relevant. As presented in the brief summaries here, a wide range of hazards not only pose dangers to societies around the globe, but also creates challenges that undermine effective governance. The combination of threats and instability that arise from crises present novel challenges for organizations, governments, leaders, and every person around the world. On this page, you can learn about various global security problems, including how they threaten society, and the organizations working to mitigate their impacts. These are a handful of the challenges facing today's world, which will require innovative, sustainable, and inclusive solutions.
