The Editorial Board would like to thank the Springer staff for their support. We are thankful to all of the reviewers for their efforts in providing valuable feedback. And of course, we are thankful to the authors who have submitted their research over the years. Heading into the seventh year, we will continue to seek creative ways to grow the reputation and readership of the journal. The journal has exhibited encouraging trends in metrics, including the Google Scholar metrics. The h5-index for the previous 5 years (2013-2017) rose to 18, up from 16 last year. The h5-median score is 29. In terms of journals with the word "decision" in the title, Environment Systems and Decisions was ranked 16th. The most cited paper has 84 citations as of the writing of this editorial, with the second and third most cited having 69 and 45 citations. These metrics indicate that the research published here is having an impact. The first article in this issue continues the year-long theme of resilience. In this paper, Woods (2018) describes the concept of graceful extensibility, or the ability of systems to adapt to changing environments. This concept is the opposite of brittleness, where systems are prone to failure when pushed beyond their operating limits. This paper, along with the others in the previous issues, collectively addresses the important and growing field of resilience research relevant to many engineering, social science, and environmental applications. The interdisciplinary nature of resilience analysis is perfect for Environment Systems and References Ali Y, Aslam Z, Dar HS, Mumtaz U (2018) A multi-criteria decision analysis of solid waste treatment options in Pakistan: Lahore
