I was invited by LASALLE College of the Arts, Singapore in April 2022 to give a public lecture online on the topic: “Our eco-cities: The role of arts and creatives“. In this public presentation we focused on the key trends and challenges in the environmental management in the 21^st century, related to arts and creative industries at a city level. I provided arguments why culture is a smart investment for cities and what are the strategies and tools of creative organisations to deal with environmental challenges. The presentation emphasized on the essence and diversity of creative clusters and their role in culture-led regeneration strategies of cities. We shared plenty of examples from different corners of the world to provide a flavour of the richness in arts practices for sustainability at city-level.
