The Berlin International Literature Festival is calling for a day of reading Darwish’s poetry, world-wide, on October 5th. The site doesn’t have details about planned activities, but I like to imagine people reading his poems out loud around the globe.
there will be a reading in Cairo:

and another one in Alex organized by Bibliotheca Alexandrina.
