Water is an essential resource for human life. Ensuring basic sanitation and clean drinking water is one of humanity's greatest challenges. In both urban and rural areas, access to water is critical for the health and well-being of communities and for the success of a wide range of human activities. 

This is why the water crisis is such an alarming threat. Rising global temperatures and natural disasters associated with climate change contribute to this scenario. Studies suggest that by 2025, approximately 1.8 billion people will face water scarcity.

Today, March 22, marks World Water Day. According to data from the UN, the organization responsible for establishing this commemorative date, by the year 2050, between 3.5 billion and 4.4 billion people will have limited access to this resource, the use of which increased sixfold over the last century and currently grows at a rate of approximately 1% per year.

In light of such concerning figures, the concept of sustainability and the importance of solutions aimed at water conservation and reuse become even more critical.

Twelve thousand years ago, our ancestors noticed that wherever a seed or fruit fell, a plant grew. Realizing they could intentionally plant seeds and harvest them later, they stopped migrating in search of food and settled permanently where they could cultivate. In doing so, they began establishing the world's first cities and inventing what we now call agriculture.

In today's global landscape, bridging architectural studies and public health is highly critical. The year 2020 brought the world to a standstill, underscoring the urgent need to focus on the most vulnerable areas. How can we guarantee high-quality public services equally to an entire population when the urban environment of one segment is so deeply compromised? Finding answers to this question is essential to planning a sustainable future for humanity. 

To this end, this article reflects on spatial socioeconomic inequality, positioning architecture as a tool for transforming these spaces. It presents data on the housing and urban conditions of substandard settlements (referred to by the Brazilian Institute of Geography and Statistics - IBGE as "subnormal agglomerations") and analyzes the neglected diseases affecting these communities.

The 27th World Congress of Architects launched its online program this week, preceding the in-person events scheduled to take place between July 18 and 22. Social inclusion, the periphery, and architectural interventions in favelas were the topics of debates featuring Fabienne Hoelzel, Maria Alice Rezende de Carvalho, Alfredo Brillembourg, Jorge Mário Jáuregui, Alejandro Echeverri, and Adriana Levisky.

Imagining and experiencing alternative ways to understand the relationship between the human body, space, and the ideas that connect it to the world was one of the central themes that Hundertwasser brought to light. The Austrian artist and architect, born in 1928, dedicated much of his work to environmental issues, expressing his perspective through the theory of the five skins: the epidermis, clothing, the home, social identity, and the world. Due to its universality, this concept retains a contemporary relevance.

Pier Luigi Nervi is a curious case in architectural history. He designed large reinforced concrete buildings—and was even responsible for technical developments related to this material—defined by their bold, expressive, and heroic structural concepts. His design method was similar to Le Corbusier's during his so-called "Brutalist phase," which "(...) approached the architectural program starting from general principles, subsequently adapting them to the real situation. The project was defined by the structural concept [partido], which was organized from the general to the particular" (Acayaba, 1985). This is evident in the Italian's buildings, which are largely pavilion-like structures in which a massive structural roof spans the specificities of the program.

The construction of streets throughout the twentieth century was largely based on the premise that more infrastructure eases traffic. Evidence shows, however, that instead of reducing congestion, building more roads actually increases traffic. Reducing drive times makes driving more convenient; consequently, coupled with the status-symbol appeal of private vehicles, people tend to make more trips by car. A recent study by researchers at the University of Barcelona analyzed data from 545 European cities between 1985 and 2005, confirming that two decades of efforts to expand road capacity led to an increase—rather than a decrease—in vehicle traffic, failing to alleviate congestion.

The book “The High Cost of Free Parking,” by retired University of California professor Donald Shoup, demonstrates that parking can impose a significant social cost. Shoup argues that the car-centric city model is irrational, allocating increasingly more resources and space to a machine that goes unused 95% of the time.

Last week, we announced the 15 finalists for the 2021 Obra do Ano, an award celebrating the best of Lusophone architecture by inviting our readers to select their favorite projects built in Portuguese-speaking countries. The day has come to find out the winners of ODA 2021.

In the face of contemporary changes, architects and urban planners must revisit their roles. In contrast to planning approaches that produce increasingly massified and generic cities, establishing practices of resistance to reclaim the city for pedestrians is paramount. To be effective, these practices must foster connections between the people who experience the city daily and the urban space itself, moving away from technical definitions that treat public participation as fragmented. Instead of fueling collective paranoia that builds insurmountable walls in search of excessive security, the city should align with technology to promote openness, open-source models, collaboration, and collective creation. Beyond its practical connective function, the street must enhance lived experiences, becoming a space for chance encounters, reflection, and, above all, appropriation.

Madrid will demolish the M-30 highway overpass, located between the Puente de Vallecas and Retiro neighborhoods. This was the unanimous decision of the councilors of the Plenary of the Ayuntamiento de Madrid—the city's elected municipal council—who met on March 30. According to the author of the proposal, councilor and member of the Más Madrid party Francisco Pérez Ramos, the decision is crucial because the overpass has turned “into a wall.”

From using linguistic theory as an analytical methodology in architecture to understanding buildings as mediums of communication, the intersections between language and architecture are closer than they might first appear. 

Understanding the building as a medium of communication can occur in various ways—such as integrating paintings, engravings, sculptures, and ornamentation into the architecture—but also through the literal incorporation of letters and symbols as architectural elements.

Designing spaces below ground level is always a major challenge, particularly regarding lighting and ventilation. However, creative solutions make it possible to create welcoming, airy subterranean spaces, such as the use of perforated panels to bring light into Casa K or even the strategic implementation of a glass-bottomed reflecting pool on the ground floor, allowing natural light to reach the basement of Jardim do Sol House.

Designed to allow light to pass through spaces while ensuring greater privacy for users, the use of reeded glass expands the possibilities of applying glass in architectural projects.

The grooves that characterize reeded glass are produced through the drawing process of flat glass, fragmenting the image passing through the surface into vertical or horizontal bands, depending on its orientation.

While working on Raid on Bungeling Bay—a game about bombing cities—legendary game designer Will Wright discovered he had more fun designing the cities than destroying them. He then wondered if players would enjoy having that same opportunity.

Four years later, the result was SimCity, a game that broke away from traditional gaming conventions by swapping levels for open-ended gameplay and clear objectives for a sandbox—a blank slate for creativity. Players were given an empty plot of land, a pile of cash, and a few basic planning tools, and then left to do as they pleased.

In primitive huts thousands of years ago, humans used animal skins and tree branches to build their shelters—the very same materials used to protect their bodies from the elements. From clothing to housing, these textile elements have accompanied human history, evolving alongside technology and securing a place in architectural production that goes far beyond membrane structures made of polyester/PVC and canvas. Today, they can be seen in other applications such as facade panels, interior partitions, openwork canopies, and more.

Art Nouveau, or new art, was an artistic movement that emerged in Belgium in the late 19th century and rapidly spread across several European countries and the United States. It was "new" art because it rejected academic canons and marked a break with the past. Spurred by the developments and societal changes brought about by the Second Industrial Revolution, the movement's artists sought to create a visual language that aligned with the advancements of their time, transcending antiquity, academicism, and aesthetic conservatism. Consequently, their works combined classical elements with contemporary details, merging different styles to form an original whole.

Throughout the 20th century, road construction was primarily based on the premise that more infrastructure eases traffic. However, evidence shows that instead of reducing congestion, building more roads actually increases traffic. When driving times are reduced, convenience increases. Consequently, alongside the appeal of private vehicles as status symbols of wealth and social standing, people tend to make more trips by car. A recent study by researchers at the University of Barcelona analyzed data from 545 European cities between 1985 and 2005. It confirmed that efforts to expand road capacity over those two decades led to an increase rather than a reduction in vehicle traffic, and failed to ease congestion.

The global transition to a green economy could create 18 million jobs, with the potential to generate quality employment and livelihoods worldwide. But what about the people and communities whose livelihoods currently depend on fossil fuels and high-carbon sectors?

An estimated 6 million jobs in coal-fired power generation, oil extraction, and other sectors could disappear by 2030. Many of these new green job opportunities will require different skills than those needed for previous roles, or will be located in new areas.

While they can serve various functions in many projects, stairs are, first and foremost, elements of vertical circulation used to connect two or more levels. Due to the relatively intermittent nature of their use, many designs for small spaces leverage this characteristic to explore solutions that go beyond traditional configurations and standard riser dimensions.

The relationship between architecture and structure has been widely discussed and is repeatedly revisited by architects with every new project. Much like plumbing and electrical systems, the structural system is one of the essential disciplines that make up a building. Yet, it is one of the most impactful on the architectural outcome, directly shaping the spatial experience and the chosen materiality. Mastering structural design and understanding how to best integrate it into the architectural project grants architects greater autonomy and expands the possibilities of design solutions. 

Selecting a structural system and deciding how to incorporate it into the architectural design is a pivotal decision in any project. On one hand, architects can choose to absorb structural elements, camouflaging them within the building envelope to make them imperceptible. On the other, the structural system can be brought to the forefront, turning into a defining feature of the design—whether through its structural logic, its materiality, or by being elevated to a nearly sculptural element.
