I attended a discussion on the future of Lagos; held on Friday June 18, 2010 at the School of Oriental and African Studies (SOAS), and organised by Bukka, a UK-based educational trust, and wrote a piece for my paper, NEXT. It was published in the Monday, June 28, 2010 edition.
The discussion was moderated by Kaye Whiteman, former editor of West Africa magazine and author of a forthcoming book on Lagos; and had as panelists Kunle Adeyemi, architect with the Holland-based international architecture practice OMA (the firm designing the proposed Lagos 4th Mainland bridge); Simon Gusah, a Planning Consultant who divides his time between Abuja and London; and Urban Detectives, a Holland-based partnership that recently organised a series of “City Space Investigations (CSI)” workshops in Lagos.
