I am a tenured geology professor at Vassar , an elite liberal-arts school . I research, teach and write about the complex and intimate connections between land and water resources and social justice. For the study trip I led to Israel and the Palestinian territories, I created a syllabus designed to explore difficult issues and engage diverse perspectives that was vetted by Vassar’s faculty and administration. I have successfully led numerous similar trips to locations such as the Appalachian Mountains and the Mojave Desert. My modest goals for such trips are to impart knowledge and share experiences with my students that can be realized only by traveling to the regions we are examining. In studying arid regions without seeing the situation with their own eyes, it is difficult for students from places where water is relatively abundant to think about solutions to the problems that occur when local residents must share a meager supply.
