One of the books on the shelf is labeled UNESCO. At the time of her injury, Aunt Darcy was working as a consultant to UNESCO on the topic of Transboundary Aquifers. Findings from her consulting work are to be included in the book for WaterRocks Publishing.
To learn more about the importance of this work, you contact her friend and colleague hydrogeologist Alice Aureli to glean more information that might be useful since you know nothing about the topic. Over the phone, Alice Aureli of UNESCO describes what a transboundary aquifer is, the history of mapping transboundary aquifers, and the draft agreement on transboundary aquifers.
The UNESCO book you pulled off the shelf also contains two major illustrations: a map and a table of TransBoundary Aquifers around the world.
