Access to reliable and affordable energy, water, and services is an important determinant of the prosperity of cities along with effective mission sustainment at military installations. The idea for this book was conceived at the NATO Advanced Research Workshop (ARW) in June 2012 in Hella, Iceland. The workshop was attended by 50 scientists, engineers, and policymakers representing 15 different nations and multiple fields of expertise, reflecting the global and interdisciplinary nature of climate change and sustainability research. The focus of the workshop was on ways in which military installations and small cities can integrate energy, water, and infrastructure sustainability strategies into city and installation management plans that account for climate change uncertainties. The organization of the book reflects major topic sessions and discussions during the workshop.
