Superstorm Sandy inundated Lower Manhattan, causing billions in property and infrastructure damage. To protect against future flooding, storm surges, and sea level rise, landscape architects are developing an innovative mix of green and grey solutions along the southern coast of Manhattan.
These are not nature-based solutions but forms of armor. And designers are showing how this armature can be woven into the public realm, creating new kinds of infrastructure. Smart design is resulting in retractable gates and walls, landscaped berms, and raised platforms. No concrete walls separating communities from each other or the waterfront here.
It's that time of year again: students and their families are busy preparing for the start of school, while some of us are gearing up to step in front of the classroom. While preparing to teach an intro course on climate, I'm reminded of why we use the term climate change and not global warming.
Yes, the Earth is warming from a thickening layer of greenhouse gases in the atmosphere caused by us. But climate changes range from sea level rise to increasing storms, floods, fires, and drought, which are all negatively impacting biodiversity as well. So, not just warming. Recent storms that battered the eastern U.S. coast and Bermuda remind us of this difference. While some communities face extreme heat, others brace for storms and rising waters, and many face multiple impacts.

“This is going to be amazing! I feel so excited,” says Zhu Pei about his now under-construction Majiayao Ruins Museum and Observatory in Lintao, Gansu province. The Beijing-based architect designed his building like a deeply embedded cavernous space evoking a giant fragment of ancient pottery, resembling an archaeological site from the Neolithic Age discovered here a century ago. The building is so unusual that it cannot be described in common architectural terms. For example, a vast cast-in-place concrete hyperbolic shell lies prone on the ground, blocking the cold wind from the northwest in winter. The architect used the sand and gravel from the local Tao River to produce a special rough concrete with horizontal scratches on the surface, symbolizing the traces of thousands of years of erosion. All of Zhu’s buildings are quite remarkable. Yet, despite their novelties, they are rooted in culture, nature, and climate. They are designed based on his architectural philosophy, Architecture of Nature, articulated in five fundamental points: incomplete integrity, sponge architecture, cave and nest, sitting posture, and structure and form.
In November of 2022, the coastal city of Sharm El Sheikh, Egypt, hosted the 27th convention of the United Nations Conference of the Parties, known as COP27. Since signing the Paris Agreement in 2015, the nearly annual conference has gained momentum as a global leader in sharing knowledge and developing frameworks to mitigate climate change worldwide. While the more recent COP28, held in Dubai in 2023, focused on conversations of energy production, this previous conference focused on urban contexts, as they deal with the urgent need for incorporating loss, damage, and climate reparations into climate action plans. As two years have now passed since COP27, it is important to revisit these discussions and hold governing bodies accountable for the promises made and the benchmarks set for climate change mitigation. One of the most ambitious plans from COP27 highlights an urgent debate in our urban environments: how will we define loss, damage, and climate reparations in the twenty-first century?
Developers often make it sound as though their latest LEED platinum office building will single-handedly reverse climate change. The unfortunate reality is that they could spend a lifetime designing and building all of their work to meet the highest environmental standards, but it wouldn’t fix the problem. The planet will grow hotter, the seas will rise, and storms will intensify. A century of burning fossil fuels has baked global warming into the atmosphere for our lifetime.
“Embodied carbon accounts for 75 to 95 percent of the greenhouse gas emissions from landscape architecture projects,” said Chris Hardy, ASLA, PLA, senior associate at Sasaki, during the third in a series of webinars organized by the ASLA Biodiversity and Climate Action Committee. But by selecting locally made low-carbon materials, landscape architects can significantly reduce the climate impacts of their work.
Embodied carbon emissions are generated from the extraction, manufacturing, transportation, and construction of landscape materials. The other share of project emissions come from operating and maintaining a landscape.

A Trombe wall is a passive solar building feature that enhances thermal efficiency. Positioned on the sun-facing side of a structure, it consists of a wall made from materials like brick, stone, or concrete, and a glass panel or polycarbonate sheet placed a few centimeters in front of it. Solar radiation penetrates the glass during daylight hours and heats the masonry wall. This wall then slowly releases the stored heat into the building during the cooler nighttime hours, maintaining a more consistent indoor temperature without the need for active heating systems.

The world has changed, and accepting this fact is no longer a matter of choice but survival. Our rainfall patterns, periods of drought, average temperatures, sea levels—everything is in constant flux. The denialist stance of many countries, including Brazil, has led to catastrophic situations like the one we are facing now.
The floods that devastated the southern region of the country in recent days cannot be considered isolated incidents. Due to global warming, climate events like this will become increasingly frequent. In other words, unfortunately, we cannot prevent them from happening, but we can—and must—make our cities more resilient to these situations.
Carlo Ratti, the curator of the 19th International Architecture Exhibition - La Biennale di Venezia, along with The President of La Biennale di Venezia, Pietrangelo Buttafuocco, have just revealed highly anticipated details for the upcoming edition. Titled "Intelligens," the exhibition will be running from May 24th to November 23rd, 2025 in Giardini, the Arsenale, and various landmark locations throughout Venice.
Social infrastructure encompasses the resources and services that allow the creation of communal bonds and social connections. Within the built environment, it manifests through public spaces like parks, libraries, and community centers alongside threshold spaces such as public transportation stops.
These public social spaces play a crucial role in strengthening communities and, in turn, their ability to respond to catastrophic climate-related events. They can provide physical shelter to the populations most vulnerable to these events and foster resilient networks of people who can more quickly recover. Given the escalating frequency of extreme weather events in the United States due to climate change and its social infrastructure inadequacies, examining public spaces as a critical tool for climate resilience becomes vital.
Every year, Earth Day, celebrated on April 22, presents us with an opportunity to contemplate the conditions of our planet and our impact upon it. Generating around 37% of global carbon emissions, the construction industry has an important, often detrimental, role to play, thus placing an increasingly urgent responsibility on architects and builders to devise strategies for reducing this number. Still, the built environment represents the habitat for most of humanity, and so it has the potential to protect and shelter people from the risks posed by the changing climate. Read on to discover a collection of articles delving into the strategies available at urban and architectural scales for mitigating the effects of climate change and minimizing the industry’s impact upon it.
When delving into the envelope of construction and examining how the interior relates to the exterior, the concept of greenhouses emerges as an opportunity to cultivate life indoors, whether dependent on external factors or not. Defined as spaces enclosed by glass or other transparent plastic materials, greenhouses facilitate the growth of vegetables and ornamental plants even during periods of adverse external weather conditions. However, what does designing for plants involve?Climate, species, structural design, and the type of covering are just a few of the considerations to take into account.

Zaha Hadid Architects have unveiled a large-scale project for the redevelopment of the Al Khuwair waterfront in downtown Muscat, the capital of Oman. The $1.3bn project covers an area of 3.3 million square meters. It aims to revitalize the area through sustainability-led design principles to accommodate the expected population growth, which is expected to almost double by 2040. The plans are developed in collaboration with Buro Happold to incorporate and transform the existing buildings on site, introduce coastal and climate resilience measures, and create an efficient transit-oriented infrastructure.

“Landscape architects have started conversations about embodied carbon. There is a realization that we can no longer ignore the grey parts,” said Stephanie Carlisle, Senior Researcher, Carbon Leadership Forum and the University of Washington, during the first in a series of webinars organized by the ASLA Biodiversity and Climate Action Committee.
The grey parts are concrete, steel, and other manufactured products in projects. And the conversations happening are laying the foundation for a shift away from using these materials. The landscape architect climate leaders driving these conversations are offering practical ways to decarbonize projects and specify low-carbon materials.
As the temperature drops in the Northern Hemisphere, cold outdoor spaces are overcome with frost, ice, and snow, and we find ourselves rushing from one heated indoor environment to the next, less willing or less able to stop and appreciate the natural world around us.
Apart from dragging a spruce or fir tree inside and dressing it up in yuletide costume, we tend to leave the real natural world to its own seasonal devices until it reemerges in Spring. However, by inviting the positive effects of plant life into our homes, we can improve both our mental health and the air we breathe by filling them with peace and joy all year round, not just at Christmas.
On November 30, 2023, the UN COP28 climate summit begins in Dubai, the United Arab Emirates. The name stands for the Conference of the Parties under the UNFCCC, and symbolizes the annual meeting of world governments for the purpose of establishing strategies to limit the extent of climate change and its adverse effects. Last year’s summit concluded with several important measures, including the promise of a global fund aimed at providing financial aid to developing countries affected by climate disasters.
The main purpose of COP is to reinforce the commitments of the Paris Agreement, signed in 2015, which strives to keep the global temperature rise under 1.5C degrees. As the construction industry accounts for 39% of global emissions, architecture plays an important role in helping to lower our carbon footprint, making COP28 a crucial event for architects.
In a bid to explore new materials and methods for more sustainable construction, Henning Larsen opens the “Changing our Footprint” exhibition at the Danish Architecture Center in Copenhagen. The initiative, open from November 17, 2023, until March 3, 2024, aims to showcase ideas for more climate-friendly architecture and to start conversations on architecture and construction’s role in mitigating the effects of climate change. This represents the second iteration of the exhibition, as the first version opened at the Aedes Architecture Forum in Berlin earlier this year.
Some of the most picturesque projects are those built in the mountains; the rustic cabin wrapped with a floor-to-ceiling glass panel that overlooks the snow-covered trees. Visually, the architecture exudes an enchanting feeling, but is it truly a habitable space? When houses are built on an elevation of 3,000 meters, installing a fire element alone is not efficient or sustainable. Spaces on such altitudes or particular geographic locations require to be treated thoroughly, beginning with the architecture itself. Whether it's through hydronic in-floor heating systems or wall-mounted chimneys, this interior focus explores how even the most extreme winter conditions did not get in the way of ensuring optimum thermal comfort.
