David Yetman

​David Yetman is a research social scientist and has been at the University of Arizona Southwest Center since 1992. He received his doctorate in philosophy from the U of A in 1972.

Yetman’s research has been directed toward the indigenous people of Sonora and their history. He has written extensively on the native uses of desert plants and in 2002 co-authored Mayo Ethnobotany: Land, History, and Traditional Knowledge in Northwest Mexico. In his 2007 volume, The Great Cacti: Ethnobotany and Biogeography of Columnar Cacti, Yetman documents columnar cacti throughout the Americas. He recently co-authored a forthcoming book about the iconic Sonoran Desert cactus, the saguaro, expected to be published this year by University of Arizona Press.  

In addition to his writing, Yetman served for nine years as host for the PBS documentary television series The Desert Speaks and currently produces and hosts the PBS series In the Americas with David Yetman. Yetman received Emmy Awards in 2007 and 2014 for his documentary television work.

The title of his talk says it all:

Why I love deserts and why you should as well—especially the Sonoran Desert

Talking About Value: How to Own the ROI Conversation

Librarians and information professionals understand the value we provide to our organizations. Unfortunately, we are often competing against the perception that it’s all available for free on the web. Mary Ellen Bates will offer fresh perspectives on how to see ourselves and our libraries as strategic resources, how to look at our services from our clients’ perspective, and how to communicate our value in ways that get heard. This lively session will end with Mary Ellen brainstorming compelling messages based on participants’ success stories.
