Environmental, urban planning and policy issues figure prominently in the world today. In particular, the growing complexity in city planning and development, as well as the sustainability of natural and urban ecosystems has been put into question by environmental degradation, loss of biodiversity, demographic change, consumption patterns, and depletion of or lack of access to resources. The Bachelor of Engineering with a Second Major in Society and Urban Systems programme, jointly offered by the College of Engineering (CoE) and College of Humanities, Arts and Social Sciences (CoHASS), offers students an insightful interdisciplinary study on contemporary urban systems. Students will acquire understanding and develop appreciation for the rationale and processes behind the emergence, growth and evolution of the urban built environment from its natural environment.
