About the book

World population now stands at almost 7 billion and if current trends continue, more than 11 billion people will populate our planet by 2050. Large youth populations, massive migration, and differential growth among ethnic groups suggest that the 21st century will undoubtedly include multiple threats to national security: interstate wars, civil conflict, and millions of deaths from poverty and disease. At the same time, urbanization and maturing age structures will create new opportunities for peace and prosperity.

The Future Faces of War: Population and National Security--the first comprehensive book on demography and security in a decade--analyzes the challenges faced and posed by great powers, such as Russia and China; strategic states, like Pakistan and Iran; and rising powers, including Brazil and India. Through analysis aimed at policymakers and general readers, International Relations scholar Jennifer Dabbs Sciubba identifies the trends that offer opportunities for building partnerships and strengthening security, and those that challenge global and civil peace.

Understanding population growth and other demographic trends is crucial to national security, as population issues play a central role in efforts to ensure national defense, avoid societal collapse, and meet citizens’ basic needs. Focusing on multiple scenarios and the theoretical links between population and security, Sciubba’s insights will remain relevant for years to come.
