I appreciate Dr. Agha's teaching as I was unaware of this Nubian history.  The Nile River and surrounding flood plains are contested and were an easy target for colonizers.  I appreciate Agha's insight into how names are created, who comes up with them, and what they reflect.  There is a movement to revert back to indigenous names in my region and to let go of names given by those who claimed land as their own.  I admire the Nubian's claim on their ancestral land, underwater and seemingly lost.  By holding on to that belief, they show a strength and resiliency.  The whole section on architecture of homes offered to the displaced Nubian's is also interesting.  Examples of this have occurred throughout history.  I think of the resettlement homes in Hong Kong where I lived until age 8, high rise buildings with hundreds of families crammed in; the sections of land our government pushed indigenous groups on to, now called "reservations": and the Three Gorges and villages on the Yangtze River in China that were flooded when new dams were constructed in the name of progress.  I also found her comment connecting the title of "marginalized" with the idea that the marginalized don't deserve spacial justice.  They are the first to lose their spaces in the name of progress.  

As far as how I might bring this into the classroom, I can see connections to the on-going construction of the now double border wall at the US/Mexico border and how that is a concern of spacial justice.  To avoid getting too political, I might consider working with data provided by Sky Island Alliance, a nonprofit that collects data on sky islands, elevated land in S. Arizona and N. Mexico that becomes a unique ecosystem housing animal life that migrates from one sky island to another.  They have wildlife camera trap videos for community scientists (previously "citizen scientists") to view and study data on how human made structures impacts their existence.  This might be a way to introduce the concept before pulling out other examples of impact  when humans change geography.
