In March, the UC Berkeley Environmental Planning studio travelled to Barreiro, which is located in the Lisbon Metropolitan Area, lying in the South Bank of the Tagus Estuary Lisbon, Portugal. The students participated in a one-week workshop over spring break, working with post-graduate students from Lisbon and Ghent to study how to enhance the ecological benefits provided by the proximity to the estuary, how to cope with changes introduced by shifting economic conditions and sea-level rise, and how to improve connectivity along, and to, the city’s estuarine shorelines, bearing in mind the environmental and social issues at play.
