Today, more than ever before, a threat to one is a threat to all. Threats to international peace and security go far beyond aggression by States and include poverty, deadly infectious disease, environmental degradation, civil war, weapons of mass destruction, terrorism and transnational organized crime. This report by 16 of the world's most experienced leaders, commissioned by the United Nations Secretary-General, puts forward a bold new vision of collective security that stresses the need for effective, equitable action in preventing and responding to all major threats to international peace and security.

Commissioned by the UN Secretary General, the report of the High-level Panel on Threats, Challenges and Changes explores a range of current and evolving threats to international peace and security, and assesses how well existing policies and international institutions have done in addressing these challenges. The report was written by an independent panel of 16 people comprising former heads of state and foreign ministers, as well as security, military, diplomatic and development officials. It makes a number of recommendations to strengthen the international framework of collective security and to promote a more effective UN for the 21st century, based on the recognition that today's security threats, whether they be terrorism, civil wars or extreme poverty, are all interconnected and require comprehensive strategies to address them. This Command Paper sets out the text of the report with the aim of stimulating a public debate in the UK on the issues raised.

A new approach to safety, based on systems thinking, that is more effective, less costly, and easier to use than current techniques. Engineering has experienced a technological revolution, but the basic engineering techniques applied in safety and reliability engineering, created in a simpler, analog world, have changed very little over the years. In this groundbreaking book, Nancy Leveson proposes a new approach to safety—more suited to today's complex, sociotechnical, software-intensive world—based on modern systems thinking and systems theory. Revisiting and updating ideas pioneered by 1950s aerospace engineers in their System Safety concept, and testing her new model extensively on real-world examples, Leveson has created a new approach to safety that is more effective, less expensive, and easier to use than current techniques. Arguing that traditional models of causality are inadequate, Leveson presents a new, extended model of causation (Systems-Theoretic Accident Model and Processes, or STAMP), then shows how the new model can be used to create techniques for system safety engineering, including accident analysis, hazard analysis, system design, safety in operations, and management of safety-critical systems. She applies the new techniques to real-world events including the friendly-fire loss of a U.S. Blackhawk helicopter in the first Gulf War; the Vioxx recall; the U.S. Navy SUBSAFE program; and the bacterial contamination of a public water supply in a Canadian town. Leveson's approach is relevant even beyond safety engineering, offering techniques for “reengineering” any large sociotechnical system to improve safety and manage risk.

Deliberately challenging the traditional, state-centric analysis of security, this book focuses on subnational and transnational forces—religious and ethnic conflict, climate change, pandemic diseases, poverty, terrorism, criminal networks, and cyber attacks—that threaten human beings and their communities across state borders. Examining threats related to human security in the modern era of globalization, Reveron and Mahoney-Norris argue that human security is national security today, even for great powers. This fully updated second edition of Human and National Security: Understanding Transnational Challenges builds on the foundation of the first (published as Human Security in a Borderless World) while also incorporating new discussions of the rise of identity politics in an increasingly connected world, an expanded account of the actors, institutions, and approaches to security today, and the ways diverse global actors protect and promote human security. An essential text for security studies and international relations students, Human and National Security not only presents human security challenges and their policy implications, it also highlights how governments, societies, and international forces can, and do, take advantage of possibilities in the contemporary era to develop a more stable and secure world for all.

"The ongoing COVID-19 pandemic marks the most significant, singular global disruption since World War II, with health, economic, political, and security implications that will ripple for years to come." -Global Trends 2040 (2021) Global Trends 2040-A More Contested World (2021), released by the US National Intelligence Council, is the latest report in its series of reports starting in 1997 about megatrends and the world's future. This report, strongly influenced by the COVID-19 pandemic, paints a bleak picture of the future and describes a contested, fragmented and turbulent world. It specifically discusses the four main trends that will shape tomorrow's world: - Demographics-by 2040, 1.4 billion people will be added mostly in Africa and South Asia. - Economics-increased government debt and concentrated economic power will escalate problems for the poor and middleclass. - Climate-a hotter world will increase water, food, and health insecurity. - Technology-the emergence of new technologies could both solve and cause problems for human life. Students of trends, policymakers, entrepreneurs, academics, journalists and anyone eager for a glimpse into the next decades, will find this report, with colored graphs, essential reading.

The 2011 WDR on Conflict, Security and Development underlines the devastating impact of persistent conflict on a country or region's development prospects - noting that the 1.5 billion people living in conflict-affected areas are twice as likely to be in poverty. Its goal is to contribute concrete, practical suggestions on conflict and fragility.
