This course is designed for postgraduate students who want to learn about urban sustainability, an emerging and still developing field that draws on different disciplines, such as industrial ecology, urban political ecology, urban ecology, and planning and how public policy and public management approach it. It will explore how to make cities more sustainable in terms of environmental, social, and economic aspects and equip students with the theoretical and methodological tools to draft and analyze strategies and their viability. The course will also introduce and evaluate various approaches to foster more sustainable and resilient forms of urbanization and urban life, such as localization, industrial symbiosis, and ecological restoration and review processes of reducing the dependence on external resources and increasing the local production and consumption of goods and services. These approaches will be examined in different contexts and scales, from local to global, and from individual to collective.
