This volume contains the proceedings of a symposium that took place during the 2011 annual meeting of the American Association for Applied Linguistics (AAAL) in Chicago, Illinois. The purpose of the symposium was to present the Sustainable Use Model for Language Development (SUM) and, in particular, to demonstrate the application of the Expanded Graded Intergenerational Disruption Scale (EGIDS) as a means of describing language ecologies in different parts of the world.

The book consists of 3 introductory chapters which give an overview of the Sustainable Use Model. Chapter 1 (Lewis), gives a general overview. Chapter 2 (Simons) gives a more detailed description of the EGIDS and the FAMED conditions and includes an EGIDS evaluation tool as an appendix. Chapter 3 (Karan, forthcoming) provides an explanation of the Perceived Benefit Model which serves as the basis for the SUM's description of Motivation, one of the FAMED conditions. These foundational chapters are followed by four cases studies in which the language ecologies of Brazil (Anonby, Chp. 4), Bangladesh (Kim, Chp. 5), Democratic Republic of Congo (Bagamba and Boone, Chp. 6) and Malaysia (Lewis, Moody and Rose, Chp. 7) are described by using the EGIDS to develop a profile of language vitality in each country. A final chapter, (Quakenbush, Chp. 8) summarizes the lessons learned from these case studies.
