Cities that absorb rainwater and allow it to follow its natural course. It should be simple, yet we chose to channel our waterways, preventing nature from doing its part: absorbing and purifying. For Chinese architect Kongjian Yu, this is the key to solving one of the greatest challenges facing contemporary major urban centers: flooding. 

There is no doubt that preserving historical, artistic, and architectural heritage is a fundamental goal for building a just city. It is the right of all citizens, both present and future generations, to know and enjoy our collective memory and culture. However, for this to actually happen, both a discerning eye and a comprehensive vision of the city are essential.

Over the past week, thousands of active fires in the Brazilian Amazon captured global attention in the press and on social media, where the hashtag #PrayForAmazonia was mentioned more than 150,000 times in a single day. But what can satellite data tell us about what is actually happening in Brazil's forests?

Felipe Camus, a photographer who has documented ELEMENTAL's project, shares his reflections on Ochoquebradas.

Five Brazilians die in traffic accidents every hour. While highly critical statistics like this can spark positive reactions, they are not always enough to change reality on their own. However, knowing that in the city of São Paulo intersections concentrate more accidents per kilometer, and that these rose by 5% from 2017 to 2018, provides decision-makers with the concrete data needed to implement measures to reduce these numbers. Acting on the most dangerous intersections will save lives.

In the popular imagination, *cortiços* (tenement houses) represented the worst of urban housing in Brazilian cities. Deeply rooted in the national culture and immortalized in Aluísio Azevedo’s classic novel, *cortiços* were depicted as unsanitary, dilapidated dwellings where disease proliferated, the margins of society lived, and landlords exploited tenants with extortionate rents.

A quality public transit system does not depend on buses alone: its overall quality is also directly linked to adjacent elements—such as bus stops. In all cities participating in the QualiÔnibus Benchmarking Group, bus stops were identified by the public as one of the most problematic components. But what can cities do to improve them?

Anyone who has ever been to the beaches of Rio de Janeiro has certainly seen vendors selling grilled *queijo coalho* (curd cheese) or grilled shrimp, sweet mate tea, and Globo biscuits—classic snacks of the Rio shoreline. In São Paulo, open-air markets serve sugarcane juice and fried *pastel*, a local adaptation of a dish originally brought by Chinese immigrants and popularized by Japanese immigrants. In Minas Gerais, there is *pão de queijo* (cheese bread) and pastel, also filled with cheese. In Salvador, it is impossible not to mention *acarajé* (with or without hot sauce), which has been declared an intangible cultural heritage asset by IPHAN. The capital of Bahia even has its own Street Food Guide, reflecting the immense culinary diversity found in the city.

The book Sustainable Tropical Cities, published by the Institute of Tropical Architecture (San José, Costa Rica) in 2006, gathers the conclusions its authors compiled over years of observation and study. Bruno Stagno and Jimena Ugarte, both architects and immigrants enamored with the tropics, aimed to demonstrate the specific characteristics that cities located in the tropical belt possess—or should possess—while introducing an unprecedented topic.

The Museo Casa de la Memoria is located in Medellín's Boston neighborhood and was developed to commemorate the bicentennial of Colombia's independence. Led by Juan David Botero as the design team coordinator, the project was conceived from the outset as a highly recognizable building for both the community and visitors, drawing its sculptural form from traditional gabled houses. "It is a museum for the victims of violence, and as such, we had to ensure it was a space for everything; a home, the house where memory comes to life," Botero says.

The 3,800-square-meter cultural facility unfolds along the creek like a tunnel, housing exhibition rooms, workshops, archives, offices, and an auditorium. Its envelope functions as a folded skin, incorporating an air cavity that absorbs cool air, draws it in through the facade, and expels it as hot air at the top. This chimney effect helps control the typical 30ºC summer temperatures of the area, ensuring a stable and comfortable indoor climate. Below, we take a closer look at its sculptural thermal and acoustic envelope.

ArchDaily is working with CityMakers to publish a series of articles, conversations, and interviews with the key figures in urban co-production behind the Barcelona CityMakers Lab 2019, an event taking place from October 14 to 20, 2019.

On this occasion, we feature Jokin Santiago Elorriaga, director of Leku Studio, who will lead a masterclass at the Barcelona CityMakers Lab 2019. Jokin is the founding architect of Leku Studio and was responsible for the design and transformation of the Sant Antoni Superblock.

As part of a series of articles developed by Nikos A. Salingaros, David Brain, Andrés M. Duany, Michael W. Mehaffy, and Ernesto Philibert-Petit on the study of social housing in Latin America, this installment reviews examples of design strategies for its construction. Read all previous publications and the new article below.

Berlin is a global leader in urban mobility, according to the Mobility Futures study by data and consulting firm Kantar, which evaluated major world cities. The German capital topped the mobility ranking due to several factors, most notably more cost-effective travel and easy access to a broad public transit infrastructure network and shared mobility services.

Venice is undoubtedly one of the most sought-after destinations in Europe for travelers from around the world. The city boasts attractions in many areas, from gastronomy to art, and naturally, architecture—an art form deeply woven into the city's fabric, most prominently showcased at the Architecture Biennales, held since 1980. Beyond the Biennale, the island has much to offer those interested in exploring places that epitomize the relationship between past and present, the preservation of historical memory, and new technologies serving buildings in constant relation with the water.

It is well known that our cities are increasingly saturated by automobile use; mobility has therefore become a key element in any discussion on urban living, particularly in large Brazilian cities. This premise prompts us to examine and better understand which aspects of urban commuting we can prioritize for intervention, moving toward approaches where car use is less necessary. An important step in this dialogue is understanding just how time-efficient cars actually are. Mapping Lab conducted a visual analysis of 27 Brazilian capital cities using data from the here.com platform.

The casa chorizo is a residential typology historically used in Argentina, primarily in the city of Buenos Aires. It consists of a succession of similarly sized rooms connected along a longitudinal axis that open onto a gallery or courtyard, from which they receive light and ventilation. Typically built on plots between party walls, their service areas are grouped at the back. Today, numerous projects address the rehabilitation of this type of housing. These can be understood as research initiatives exploring how a city's characteristic construction matrix can be reviewed and updated to adapt to contemporary ways of living.

The new workplace paradigm, driven by digital transformation, is introducing significant changes to employee profiles and the roles people perform within their work environments. At Actiu, these shifts represent an opportunity to turn workspaces into strategic levers of change, allowing organizations to align their transformation goals with the well-being and satisfaction of their workforce.
