In most cases, these spaces are revitalised by transforming them in knowledge based development areas. The aim of this paper is to understand how these transformation projects are developed. After reviewing the theoretical framework of the triple helix model and knowledge based urban development, using a multiple case approach, we analyse four Brazilian cities that are in the process of urban revitalization: Porto Digital in the city of Recife; Porto Maravilha in Rio de Janeiro; 4° Distrito in Porto Alegre; and Centro Sapiens in Florianópolis. The 22@Barcelona project, a world reference of brownfield transformations, is used as a control case. The findings shed light on how universities, government and industry, with the society and environment contribute to the urban, economic, social and governance transformation. 2040-4468 http://hdl.handle.net/20.500.14342/4842 https://doi.org/10.1504/IJKBD.2019.098230 Brazilian cities 22@Barcelona Urban revitalisation Urban transformation Urban renewal Knowledge-based economy Innovation districts Creativity districts Triple Helix Kknowledge-based urban development Brazil Ecosystems of innovation Ciutats brasileres Dinamització urbana Transformació urbana Renovació urbana Economia basada en el coneixement Districte d'Innovació Barris de creativitat Triple Hèlix Desenvolupament Urbà Basat en el Coneixement Brasil Ecosistemes d'innovació Application of the triple helix model in the revitalisation of cities: the case of Brazil
