Abstract The linear pattern of production-consumption-disposal of cities around the world will continue to increase the emission of pollutants and stocks of waste, as well as to impact on the irreversible deterioration of non-renewable stocks of raw materials. A transition towards a circular pattern proposed by the concept of ‘Circular Cities’ is gaining momentum. As part of this urban transition, the emergent use of Nature-based Solutions (NBS) intends to shift public opinion and utilize technology to mitigate the urban environmental impact. In this paper, an analysis of the current research and practical investments for implementing NBS under the umbrella of Circular Cities is conducted. A combined appraisal of the latest literature and a survey of ongoing and completed National-European research and development projects provides an overview of the current enabling tools, methodologies, and initiatives for public engagement. It also identifies and describes the links between facilitators and barriers with respect to existing policies and regulations, public awareness and engagement, and scientific and technological instruments. The paper concludes introducing the most promising methods, physical and digital technologies that may lead the way to Sustainable Circular Cities. The results of this research provide useful insight for citizens, scientists, practitioners, investors, policy makers, and strategists to channel efforts on switching from a linear to a circular thinking for the future of cities.

Since the discovery of his work in 1997, Fritz Jahr (1895-1953) has slowly become recognized as the author of the term and concept of bioethics. Jahr's ideas on bioethics were partly different from those shaped by Van Rensselaer Potter in the 1970s and, therefore, might be helpful for the further reform and broadening of modern bioethics. In this article, the authors elucidate ideas from lesser-known works by Jahr, especially those considering animal protection and teaching.

Na primjeru koksare u Bakru zatvorene koncem 20. stoljeća, autori problematiziraju odnos industrije i grada sagledan iz perspektive lokalnoga stanovništva u suvremenosti. Rad kombinira polazišta urbanih studija, postindustrijske antropologije i studija javnozdravstvenih problema, a cilj mu je analizirati društvenu dinamiku i prijepore izazvane industrijalizacijom, kao i deindustrijalizacijom bakarskog područja. Autori se bave transformacijama koje politike i prakse (de)industrijalizacije izazivaju u ljudskoj svakodnevici u drugoj polovici 20. stoljeća. Fokus je na naracijama građana Bakra o utjecaju koksare na onečišćenje okoliša i kvalitetu života, ponajviše u zdravstvenom pogledu. Autori revaloriziraju pojam postindustrijskoga grada, propitujući što znači živjeti u gradu obremenjenom industrijskom prošlošću danas.
