Infrastructure is widely known by the population in general, defined simply as a set of fundamental services for the socio-economic development of a region, such as sanitation, transportation, energy, and telecommunication. The commonly presented examples always refer to man-made physical structures. However, a new concept of infrastructure has emerged in recent decades, driven primarily by the urgent need for reconciliation between humans and nature for the survival of species.
World Wetlands Day is celebrated every February 2nd to raise awareness of wetlands. This day also marks the anniversary of the Wetlands Convention, adopted as an international treaty in 1971. Its enactment is because nearly 90% of the world's wetlands have been degraded since 1700, decimated three times faster than the forests. However, they are essential ecosystems that contribute to biodiversity, climate mitigation and adaptation, freshwater availability, world economies, and much more.
Carbon footprint, circularity and environmental sustainability are terms that are increasingly present in many professional fields, but what do they mean? How do they relate to architecture and the built environment? We spoke with civil, environmental and sanitary engineer Lucas Rosse Caldas about these and other emerging architectural issues.
Lucas is a professor at the Graduate Program in Architecture at the Federal University of Rio de Janeiro and the Civil Engineering Program at the same institution. He participated in chapter 9 of the sixth report of the Intergovernmental Panel on Climate Change (IPCC) on buildings. He wrote several scientific and technical articles about architecture and sustainable construction.

Green corridors, or biodiversity corridors, are large portions of land that receive coordinated actions to protect biological diversity. According to Brazil’s National System of Nature Conservation Units, they strengthen and connect protected areas, encouraging low-impact use by implementing a more comprehensive, decentralized and participatory conservation alternative.
It is a great privilege to amplify the voice of architects and other built environment professionals. It is also an enormous challenge as it requires a lot of investigation and time from our content team. However, the effort is gratifying. It puts us in contact with some of the most prominent talents in our field who have been discussing subjects such as cities, metaverse, community, environment, democracy, sustainability, building technology and interiors, to mention just a few.
There was a time when buildings wanted to be mountains, roofs wanted to be forests, and pillars wanted to be trees. As the world began to go into a state of alert with the melting of glaciers and the consequent rise of Earth’s temperature, architecture – from a general perspective – was concerned with imitating the shapes of nature. Something close to human-made “ecosystems”, seen by many as allegoric and decorative, in service of marketable images of “sustainable development”.
As part of the effort to make the construction sector more sustainable in the face of the climate crisis, the bioeconomy has stood out. While the road to net-zero architecture is still very complex, the emerging shift in culture and general thinking is evident, and innovation seems to be driving this transformation.
Extreme natural events are becoming increasingly frequent all over the world. Numerous studies indicate that floods, storms, and sea-level rise could affect more than 800 million people worldwide, ultimately costing cities $1 trillion per year by the middle of the century. This suggests that urban survival depends on addressing urban vulnerability as a matter of urgency to protect the city and the population.
Over the past 60 years, architects and engineers have surrendered to industrial construction solutions, with buildings designed to be built faster and faster and at very low cost.
Over the past 60 years, architects and engineers have surrendered to industrial construction solutions, with buildings designed to be built faster and faster and at very low cost. As a more standardized and cheaper international approach to building emerged throughout the 20th century, many professionals abandoned the vernacular traditions of their ancestral cultures, which were developed over thousands of years, to fight the climatic extremes of different regions.
Agriculture and the food industry seem to have little in common with architecture, but it is precisely the overlap of these three areas that interests Ghanaian-Filipino scientist and architect Mae-ling Lokko, founder of Willow Technologies based in Accra, Ghana. Working with recycling agricultural waste and biopolymer materials, Lokko searches for ways to transform the so-called agrowaste into building materials.
Nature is often used as an inspirational source for architecture. Whether from its shapes, the extraction and use of its materials, or even the incorporation of physical and chemical processes in the technologies used, it is always relevant to look for relations between the built environment and the natural environment. Of the many ecosystems present on planet Earth, the oceans represent most of the surface and hold stories, mystiques, symbols and shapes that can be referenced in architecture.
“And the Lord God planted a garden in Eden, in the east, where He placed the man He had formed. Out of the ground the Lord God gave growth to every tree that is pleasing to the eye and good for food.”
This is how the Garden of Eden is portrayed in the first book of the bible, Genesis, which describes the origin of the universe and the heavenly place where Adam and Eve were placed. Such a paradise, despite being little characterized in the original words, has been inhabiting the imagination of the faithful and other enthusiasts of the matter for centuries. The scenes of this idyllic place, reinforced by the paintings and sculptures created over time, present a landscape considered ideal, an Edenic nature, expressed many times by the vibrant and contourless color – just like a painting by Monet –, probably emphasizing the representation of the spiritual world, where the image is seen through the contrast of colors, shadows and lights.

Discussing carbon neutrality in architecture should not only be based on local materials and new technologies, since there are many aspects that impact the construction production chain. From design to construction, without losing sight of the context and economic system of our society, the construction industry is responsible for a considerable part of the energy consumed worldwide. In order to interfere in this reality, it is necessary to expand the fronts of action, questioning the place of construction in our society.
At a time when biophilia is highly valued in architecture, natural pools become another element capable of increasing the connection with nature, enabling the creation of a recreational and contemplative space at the same time. Also known as ecological or biological pools, they reproduce an ecosystem composed of plants, rocks and even some species of fish.
Global Finance's ranking of the world's best cities to live in, during 2022 has just been released. Centered on 8 different parameters that calculate and compare the quality of life of people living in urban areas such as economy, culture, population, environment, etc., this year’s edition also took into consideration Covid-19 deaths per thousand for each country, to reflect the new reality we live in. With data from the Global City Power index, Johns Hopkins University, Statista, and Macrotrends, the list seeks to have a complete vision, putting together traditional metrics with new factors.
Claiming the first position is London, U.K, a city that although didn’t get high rankings in its Covid-19 metrics, still topped the list, mainly due to its scores in culture, accessibility, and population growth. Tokyo was selected for the second position, showing weakness in one parameter, population, as its numbers have been declining for the past 10 years. Shanghai followed next, in the third position, because of relatively low Covid-19 death figures and strong population growth. Singapore and Melbourne came in 4th and 5th positions.
Nowadays everything is “painted” green. It's green packaging, green technologies, green materials, green cars and, of course, green architecture. A “green wave”, stimulated by the environmental and energy crisis we are facing, with emphasis on climate change and all the consequences linked to global warming. This calamitous situation is confirmed by the second part of the report entitled Climate Change 2022: Impacts, Adaptation and Vulnerability prepared by the Intergovernmental Panel on Climate Change (IPCC) and presented in recent weeks. It reveals that, although adaptation efforts are being observed in all sectors, the progress implemented so far is very low, as the actions taken are not enough.

According to the architect and researcher Patrícia Akinaga, ecological urbanism emerged at the end of the 20th century as a strategy to create a paradigm shift with regard to the design of cities. With this, urban projects should be designed from the potential and limitations of existing natural resources. Unlike other previous movements, in ecological urbanism architecture is not the structuring element of the city — the landscape itself is. In other words, green areas should not only exist to beautify spaces, but as true engineering artifacts with the potential to dampen, retain and treat rainwater, for example. With ecological urbanism, urban design becomes defined by the natural elements intrinsic to its fabric.
Auckland in New Zealand has topped the ranking in the 2021 EIU's annual world's most liveable city survey. Classifying 140 cities across five categories including stability, healthcare, culture and environment, education, and infrastructure, this year’s edition of the review has been highly affected by the global pandemic. Australia, Japan, and New Zealand took leading positions, while European and Canadian cities fell down the ranking.
