In a period of budget austerity, prioritization becomes especially important for defense policymakers. In order to determine such priorities, it is first necessary to consider the nature of conflict and missions the U.S. military may face in the future. By assessing the key components, or drivers, of the future security environment (FSE), an unknowable future becomes a bit clearer. This report provides such an assessment. Drawing on qualitative data such as national security and foreign policy literature, Defense Department strategy and operational documents, and interviews with leading academics and practitioners, this study identifies the drivers of the FSE in order to guide analysis and decision making.

"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.

Taking an applications-oriented view, this unique volume delivers a forward-looking roadmap to military communications. This hands-on reference offers military and security technology practitioners insights into the key issues related to long-term development within the battlefield communications area. The book presents the technological alternatives for communication in the battlefield in unexpected situations and environments. This authoritative resource discusses unstructured formations of actors using a holistic approach that considers key capability requirements. Professionals and officers learn how to prepare for the unexpected and start building agile, adaptive and cognitive systems that are needed in future operating environments. From scenario-based capability planning...to situational and context awareness...to unmanned ground and aerial platforms, this easy-to-understand book covers the critical topics that practitioners need to master to achieve top performance in the battlefield.

An original contribution to our understanding of a phenomenon that is reshaping the world, this title thoroughly discusses the transformation of the energy security policy arena brought on by two dramatic developments – the increased potential availability of energy in many parts of the world on the supply side, and on the demand side increasing concerns over the harmful effects on the environment brought on by the use of fossil fuels. An in depth discussion specifically focuses on what energy security means to different countries, and examines which of those countries appear to be managing their energy/climate transitions successfully and which are having a more difficult time adapting to the new environment. Part 1 introduces the topic, covering the main themes and provides an overview of the chapters Part 2 provides a framework for policy evaluation, considering the evolving factors affecting energy security and the energy/climate policy trilemma Parts 3 to 6 discuss energy transitions in the carbon producing countries (Saudi Arabia, Canada, Iran, Russia, Mexico), in intermediate carbon/producing/consuming countries (China, United States, UK, Brazil, Argentina, South Africa), in carbon consuming countries (Germany, Japan, South Korea, Israel, India, Spain) and finally in carbon reduction countries (France, Denmark, Switzerland) Part 7 looks at attempts at regional/international cooperation Part 8 considers the prospects for the future, examining technological breakthroughs. This title builds on the theme of unfolding energy transformations driven by, but increasingly constrained by climate/environmental considerations. It is ideal for researchers and students in the areas of environmental politics and policy, climate change, and energy and climate security, as well as for academics and professionals.
