In pandemic lockdown of 2020, a centenary occurred: the 100th birthday of one of Landscape Architecture and Scotland’s pioneers of the nature based solution - before that term was used - Ian McHarg. Using online video conferencing, the Glasgow Urban Lab at the Mackintosh School of Architecture, the Weitzman School of Design at the University of Pennsylvania, the Landscape Institute, and the Academy of Urbanism, came together to hold a celebratory symposium, looking at the influence of McHarg, with eyes to the future. This publication captures the essence of the event, which took place on the 11th and 12th November 2020.
