Heartbroken by the untimely passing of Kongjian Yu in the beautiful Brazilian Pantanal. Grateful to have worked together on initiatives like the Ecological Urbanism Collaboration (a joint initiative between Harvard GSD and Peking University, 2016-19) and the Ecological Urbanism Field Research Seminar. Kongjian's generosity, vision, and passion inspired everyone he met. As @brunoagsm Bruno Marques, IFLA President, said at the IFLA Africa Conference: "May his memory be a blessing."
