The increasing presence of digitalization in all areas of study and work is equally evident in urban planning and management (UPM). Globally, the complex reality of today s cities, marked by continuous urban population growth and the ongoing consequences of climate change, demands extensive urban requalification. This requalification involves managing a vast amount of information, addressing socially sensitive issues, and carrying out forceful, surgical, contextualized, and immediately effective physical interventions. This work explores the potential role of Digital Twins (DTs) in this digital transformation of cities. Through bibliographic research and consultations with specialized entities, the context of the PGU was characterized, a conceptual leveling of the DTs was carried out, and the technologies involved in its development and application were presented. By studying notable case examples, the application of DTs as a tool to address the identified challenges was evaluated. Some aspects aligned with current UPM emerged from this discussion: intuitive access to rich, accurate, and up-to-date information; technological integration; transparent and participatory management; realistic simulation of projects and climate emergency scenarios. The conclusions of this work suggest the development of the Integrated Information Environment (IIE), a collaborative and multi-layered platform that allows access and management by multiple actors through data integration in a physical and ontological organization. This tool concentrates information and processes, promotes accessibility, minimizes social and environmental impacts, and generates temporal and resource efficiency. In the early part of the last century, only 10 per cent of the world s population lived in cities. However, by around 1950, when two-thirds of the global population still resided in rural communities, an increase in urbanization was observed. This process has intensified over the past two decades, and by 2007, we reached a significant milestone: for the first time, the urban population surpassed the rural population (UNITED NATIONS, 2019). With the urban population continuously growing at a faster rate than the rural population, today approximately 56 per cent of the global population – 4.4 billion people – resides in cities. By the end of the sustainable development agenda in 2030, the proportion of the population living in cities is expected to reach 60 per cent. With projections indicating a continued increase in this percentage in the medium term, by 2050, after just one century of intense and progressive urbanization, the situation will be reversed, with two thirds of the world s population living in urban areas. This will result in an additional 1.2 million square kilometers of urban area worldwide (THE WORLD BANK, 2020; UNITED NATIONS, 2019).
