Greenhouses are elegant and ingenious structures that incorporate simplicity in design while creating light-filled spaces that shape indoor climates. With walls and roofs composed mainly of transparent or translucent materials, these structures harness solar energy to create a controlled environment. As advances in materials and environmental management progress, they can seamlessly be integrated into architectural designs, offering innovative solutions that blend functionality with aesthetics. Beyond their original role in plant cultivation, they have evolved into projects that emphasize sustainability, education, and conservation. At their core, they offer experiences of exploration and discovery, showcasing the intricate relationship between sunlight, plants, and indoor environments.
The UN Food and Agriculture Organization (UNFAO) accounts for over one-tenth of the global population, approximately 800 million people, practicing urban agriculture worldwide. In the United States, millions of citizens lack access to supermarkets. Urban farmers play a crucial role in addressing food security issues in American cities.
Historically, the distance between rural and urban areas has never been greater, making traditionally rural food sources widely inaccessible. Cities initially would develop around centralized markets that brought produce from farmlands to urban centers. Today, urban agriculture is revitalizing this connection between city dwellers and agricultural products.
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 increasingly denser urban environments, there is a new-found interest in underused spaces as opportunities for further development. Representing up to 25% of cities' land area, rooftops are among the most exciting spatial resources. From sustainable infrastructure and urban farming to social spaces and cultural venues, the article looks into the potential of creating a multi-layered city through the activation of urban rooftops.
Cities are complex ecologies of intersecting natural systems and urban infrastructure. Environmental degradation has brought attention to the asymbiotic relationship between man-made and natural systems. A new economy is emerging where interdependence and environmental stewardship are valued. Designing for a circular economy requires consideration of human habitats not as towns or cities, but as bioregions.
When you come to think of it, most of the food on your plate has a history behind it - a long journey that we are unable to describe. In her book Food Routes: Growing Bananas in Iceland and Other Tales from the Logistics of Eating (2019), Robyn Shotwell Metcalfe refers to the paradox of fish being caught in New England, exported to Japan, and then shipped back as sushi, revealing a large and complex network that nobody can see when they buy takeout Japanese food at the local grocery store.
As populations continue to migrate from rural to urban areas, space is at a premium. Many settlements are becoming ever-more congested – with adequate, affordable housing in short supply and transport systems struggling to serve their respective residents. But as much the conversation about urbanization is about people, it is sometimes also about the animals that come with those people – urban livestock that play a key role at providing sustenance on an individual level, in addition to becoming an avenue for communal trade.
URB to develop the world's largest agritourism destination in Dubai, providing food security and to foster sustainability of the local communities, heritage, and cultural landscapes. In line with the city's ambition of making its rural areas restorative land facilities, "Agri Hub" targets to create 10,000 new jobs across various sectors, including a new agricultural research institute and a public farm for educational and retail purposes.
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.
Do you know what urban farms are? Have you ever thought about growing your own food at home in your garden or in specialized freezers? Transporting food for consumption in cities is one of the major environmental (and financial) pollution problems in the world today.
Since the emergence of the design profession, boosted in the Industrial Revolution with the increasing production of objects and the desire of a middle class eager to consume; designers, interior decorators and architects are known as professionals who create spaces and products to beautify the world.

On March 31st, the Health and Nutrition Day is celebrated in Brazil, factors that are gaining more and more notoriety in the society in which we live. After more than two years living through the ups and downs of the Covid-19 pandemic and facing the evident need for a healthier, more active and community reality, it is important to reflect on how architecture and urbanism can become tools for accessing healthier daily lives.
Food production is directly reliant on bees, and their disappearance could lead to catastrophic effects on humanity. There are alarming reports all over the internet about how these little insects are dying. According to the Food and Agriculture Organization of the United Nations (FAO), 75% of the world's food crops rely on bees. For example, it is only possible to have a juicy and well-developed strawberry if dozens of bees go by the flower at the right time and pollinate it. Without them, it would look more like a raisin.
Since before the first industrial revolution, sociologists, historians, and urban planners have been addressing the relationship between the city and the countryside, but this debate has become more pressing nowadays with the spread of megacities, typically with a population of more than 10 million people. With more and more people living in urban areas, it is imperative to think of solutions for food production within cities, thereby making cities more independent from rural areas, which have historically been responsible for the supply of food to the entire planet.
The idea that cities will become self-sufficient in food production in the near future is both unrealistic and naive. Nevertheless, small initiatives such as urban gardens, either at home or public gardens run by the community, might be a good starting point for a much bigger change in the future. Or perhaps they simply represent a desire to return to one's roots and achieve a slightly slower lifestyle.
ODA has just launched its latest project, an urban vision for the future of the streets of New York. The project titled Beyond the street- Reimagining the flower district proposes to transform a city block from the outside in, altering the pedestrian experience and introducing new zoning changes that would give landowners air rights or tax credits in exchange for handing over their inner courtyards to be transformed into public/private spaces.
ArchDaily had the chance to talk with Eran Chen, founding principal and executive director of ODA, about the firm’s very special proposal that seeks to improve our urban environment. Check the interview and watch ODA’s explanatory movie.
As urban dwellers become more aware of the environmental impacts of food production and transportation, as well as the origin and security of what they consume, urban agriculture is bound to grow and attract public and political eyes. Bringing food production closer, in addition to being sustainable, is pedagogical. However, generally with small size and other restrictions, the concerns of growing food in cities differ somewhat from traditional farming.
Urban gardens can occupy a multitude of places and have varied scales - window sills and balconies, slabs and vacant lots, courtyards of schools, public parks and even unlikely places, such as subway tunnels. They can also be communitarian or private. Whatever the case, it is important to consider some variables:
Framlab, an innovation studio based in Bergen and New York City has created Glasir, a community-based system for urban farming. The proposed modular structure relies on aeroponic growth systems to provide local products.
The Netherlands is the world’s second-biggest exporter of agricultural products. This is remarkable when one considers that the only country which tops the Netherlands, the United States, is 237 times bigger in land area. Nevertheless, the Netherlands exported almost $100 billion in agricultural goods in 2017 alone, as well as $10 billion in agriculture-related products. The secret to the Netherlands’ success lies in the use of architectural innovation to reimagine what an agricultural landscape can look like.
