World Urban Planning Day: An Invitation to Reflect on the Challenges Facing Cities in the XXI Century


Democratic cities must respond to contemporary demands focused on equitable conditions, the climate and the environment, fostering interaction and welcoming diversity. On World Urban Planning Day, celebrated today, Friday, November 8, the 27th International Congress of Architects – UIA2020RIO issues an invitation to reflect on the paths leading to the construction of these cities.

“In Brazil alone, the number of urban homes is forecast to rise by 50% over the next 25 years. The city of the XXI century must address the challenge of recognising the many different urban morphologies produced by the Brazilian people – clandestine subdivisions, outlying urban areas and favela slums – and find ways of bringing them into line with modern requirements, endowing them with the necessary public utilities and infrastructure. To do so, discussions of urban planning are crucial,” urges architect Sérgio Magalhães, who chairs the Executive Committee of the World Congress of Architects.

He feels that architects and urban planners have a strong commitment to the construction of this modern-day urban space.

Established by the United Nations in order to foster integration between urban planning practitioners and the societies that they serve, Urban Planning Day has been celebrated for 65 years in more than thirty countries.


With the theme “All the worlds. Just one world. Architecture 21” and an estimated public of 20 thousand professionals of the area, the 27th World Congress of Architects will turn Rio into the epicentre of the debate about the future of the cities. Promoted by the International Union of Architects (UIA) and organized by the Institute of Architects of Brazil (IAB), the event invites specialists and enthusiasts of fairer and more dynamic and sustainable cities to discuss solutions between the 19th and the 23rd of July of 2020. There are also preparatory and parallel events - such as exhibitions, seminars and workshops - happening around the country.

Registration for UIA2020RIO is now open.


Rio de Janeiro is the first World Capital of Architecture, a title that was achieved by Rio City Hall and the Institute of Architects of Brazil (IAB), and given by the United Nations Educational, Scientific and Cultural Organization (UNESCO) and the International Union of Architects (UIA). Throughout 2020, the city will host a series of events, including the 27th World Congress of Architects, the World Forum of Cities, exhibitions and public competitions. Besides showing to the world Rio’s architectonic treasures, the title is also an opportunity to reflect upon the future, to plan what is wanted for the cities from all over the planet.
